S Saccadic Reaction Time A saccade is a fast movement of an eye (or head or other part of an animal body or device) toward the onset of a visual (or auditory, or tactile) stimulus. Saccadic reaction time is defined as the time between the onset of the target and the onset of the saccade as defined by setting some velocity criteria. Satisficing The notion that a decision maker stops their search and selects a solution that satisfies some criteria, rather than continuing to search for an optimal solution.

Scaffolding provides a temporary structure or support to assist a learner in a task and can be gradually reduced and eventually removed altogether once the learner can carry out the performance on his or her own (Pea 2004). In order to determine the adjustable level of support that meets the learner’s needs at a particular time, the scaffolding process involves an ongoing diagnosis of a learner’s proficiency in the task (Pea 2004). N. Seel (ed.), Encyclopedia of the Sciences of Learning, DOI 10.1007/978-1-4419-1428-6, # Springer Science+Business Media, LLC 2012 2914 S Scaffolding Theoretical Background The concept of scaffolding grew out of Vygotsky’s learning construct, ▶ the zone of proximal development (ZPD). This construct established the notion that coaches or peers who are more capable could help learners move beyond their actual developmental level to one that meets their learning potential (Vygotsky 1935/1978). The actual term scaffolding was later defined by Wood et al. (1976). In this article, Wood et al. (1976) explained that “scaffolding consists essentially of the adult ‘controlling’ those elements of the task that are initially beyond the learner’s capacity, thus permitting him to concentrate upon and complete only those elements that are within his range of competence” (p. 90). This assistance by the adult would enable the learner to develop competence at a much faster rate than if unassisted. Although the original concept of scaffolding involved mentoring by a more experienced person (e.g., Palincsar 1986; Wood et al. 1976), more recently, educators have become interested in scaffolding provided through computer-based tools. Computer-based scaffolding focuses on learners working with software tools that distribute the cognitive task between the learner and the computer system (Salomon 1993). As the learner uses the tool, they begin to “internalize” the guidance it provides; this guidance eventually leaves a “cognitive residue” on the learner, allowing them to complete an increasing amount of the work themselves without the need of the supports offered by the computer (Salomon 1993, pp. 130–131). Once the guidance has been internalized, the learner is better able to selfregulate his or her own cognitions. This leads to improved ability to get more out of the tool and eventually improved competence even when the tool is no longer used. Although scaffolding is described in many ways throughout the literature, there are several common features associated with scaffolded instruction: 1. Recruiting and maintaining learner’s attention toward a goal: Central to scaffolded instruction is recruiting and enlisting interest (Wood et al. 1976). This can be accomplished by developing a common goal or shared understanding of what is to be accomplished (Puntambekar and Kolodner 2005). Once the common goal is established, it is important to keep the learner focused by sustaining 2. 3. 4. 5. interest and maintaining direction toward the objective (Palincsar 1986; Pea 2004; Wood et al. 1976). Another way to focus a learner’s attention is by highlighting critical features of the activity (Pea 2004). Simplifying the task: Another important aspect of scaffolding is to simplify the task by reducing the degrees of freedom or the size of the activity to make it more manageable for an inexperienced person (Palincsar 1986; Pea 2004; Wood et al. 1976). Sometimes, simplifying the task can involve off-loading some of the task onto someone or something else (Pea 2004; Salomon 1993). Modeling and demonstrating: Much of the literature on scaffolding also highlights the need to model the task or demonstrate the solution to the learner (Palincsar 1986; Pea 2004; Wood et al. 1976). This involves demonstrating the target performance along with providing explanation of the steps (Wood et al. 1976). Ongoing diagnosis and assessment: In order to determine the appropriate level of support that the learner needs, it is critical to continually diagnosis and assess the learner’s current level of proficiency (Pea 2004; Puntambekar and Kolodner 2005). One method to accomplish this is to note the discrepancy between the learner’s performance and the expected outcomes related to the critical features of the task (Wood et al. 1976). Fading support and eventual transfer: The final feature of scaffolding is to reduce the support over time and eventually remove it so that the learner is performing the task independently (Pea 2004; Puntambekar and Kolodner 2005). This can be achieved by the learner internalizing the process of using the scaffold in such a way that eventually he or she no longer requires its use (Salomon 1993). Important Scientific Research and Open Questions As technology-based scaffolding becomes more prevalent, it raises many important issues and unanswered questions. One of the major areas of debate in the literature is around the concept of ▶ fading or adapting the support over time. Many researchers describe all types of computer-based tools as scaffolds regardless of whether or not they include fading. However, Pea (2004) has argued that a scaffold without fading is Scaffolding really more of a ▶ distributed intelligence or ▶ distributed cognition, in which the task is shared between the learner and the tool, and the tool enables the work to be accomplished more efficiently and effectively. This type of tool is not designed to be removed, but instead learners are taught how to perform better through the use of it. For example, when students are taught to use a word processor for writing, they are not expected to stop using this tool, but are expected to learn how to write better through the use of it. On a similar note, Salomon (1993) discussed that there are two cases of distributed cognition: one where the task is off-loaded onto a tool or person, and the other which provides qualitative scaffolding in which the task is guided by a tool or person. He explained, “The tools, teamwork, or teacher behaviors that are more akin to the off-loading type are less likely to cultivate desired cognitions than those tools and other partnerships that are of the qualitative scaffolding kind. The former, it might be pointed out, are more likely to lead to deskilling than to the cultivation of skill mastery” (p. 133). Although scholars have argued a clear need for scaffolding with fading in order to promote transfer of learning, there is surprisingly little empirical research on the use of technology-based scaffolds which fade. This is often due to technical limitations of adding a mechanism to adaptively fade the tool. Moreover, another issue is that in order to know when to fade, the tool needs to be able to provide diagnostic assessment of the learner’s performance, which for complex tasks may not be technologically feasible (Pea 2004). Given these limitations, researchers have explored a few different ways to fade support. The most optimal alternative is to design the tool in such a way to provide different levels of support. For example, some scaffolding provides different levels of prompts for students based on assessments at specific milestones (Puntambekar and Kolodner 2005). Another option is to provide multiple scaffolding tools to provide different kinds of help for the same task and then remove some of the tools to fade the support (Puntambekar and Kolodner 2005). Finally, a third option is to allow learners to choose whether or not they need a particular scaffold. However, Pea (2004) raised an important point regarding this option: “how is it that they [the learners] are expected to know how to decide among nonadaptive choices for S scaffolding? They need scaffolds for the scaffolds” (p. 433). One solution to this problem may be to have the teacher provide this type of scaffolding to enable learners to make these types of choices. This leads to another area of discussion in the literature on technology-based scaffolds around the role of the teacher. In addition to providing sophisticated diagnosis and making decisions regarding what scaffolding tools should be available, other types of teacher roles include monitoring participation, offering explanations, clarifying misconceptions, modeling, helping students to reflect, and coordinating the whole environment (Puntambekar and Kolodner 2005). Although teacher scaffolding is clearly needed in connection with technology-based scaffolds, more research is required to “comparatively examine whether both software and teacher scaffolding functions could be achieved by software alone, by teacher alone, and what this says about whether it is important that the teacher’s support is human and socially interactive or simply that it needs to be interactive and adaptive in nature” (Pea 2004, p. 437). This need can be further expanded as ▶ Web 2.0 technologies afford the ability to have social interactions remotely. Thus, future research might also wish to examine whether in-person scaffolding versus online scaffolding provided by a person are equally effective. The final area of debate in the literature on scaffolding to be discussed in this chapter is how to deal with the use of scaffolding in classroom environments to meet the needs of a wide range of students all working within their own ZPDs. Puntambekar and Kolodner (2005) have found that one tool alone may not provide enough assistance to support the wide range of learner needs. These researchers suggested the use of ▶ distributed scaffolding or scaffolding that is distributed over many trials and numerous forms of support, such as tools, artifacts, resources, and people within the classroom (Puntambekar and Kolodner 2005). Multiple scaffolding tools may allow each learner in the classroom to take advantage of scaffolding at a time and, in such a manner, that best supports his or her individual learning needs. These researchers recommended for future research that each tool be analyzed separately to determine how each support is used by students at different developmental levels. Pea (2004) concurred that more research is needed on the use of scaffolding for students at differing levels. 2915 S 2916 S Scaffolding Discovery Learning Spaces Cross-References Definition ▶ Adaptive Game-Based Learning ▶ Cognitive Apprenticeship Learning ▶ Collaboration Scripts ▶ Computer-Based Learning Tools ▶ Distributed Learning ▶ Reciprocal Learning ▶ Scaffolding for Learning ▶ Scaffolding for Learning by the Use of Visual Representations ▶ Vygotsky’s Philosophy of Learning ▶ Zone of Proximal Development The scaffolding of discovery learning spaces originates from the benefits of strategic minimal guidance in order to enhance self-directed learners’ opt-in metacognition, decision-making, self-regulation, self-assessments, selfdirected learning, and skills acquisition.

Scaffolding Discovery Learning Spaces SHALIN HAI-JEW Information Technology Assistance Center (iTAC), Kansas State University, Manhattan, KS, USA Synonyms Automatic learning; Independent learning; Learnerdriven learning; Self-directed learning; Self-regulated learning Theoretical Background Learning for individuals and organizations is seen as salutary, health-producing, and necessary for growth, innovations, and strategic changes. Discovery learning uses cases occur in both formal and informal contexts. In work and higher education, discovery learning leads to value-added knowledge and skill-building outside the confines of formal training programs and courses; discovery learning enhances both the non-formal and informal methods of knowledge acquisition. In personal lives, learners may delve into hobbies and personal areas of interest as amateurs (people who just want to dabble), novices (people who want to sometime attain expertise), and lifelong learners. Traditionally, three models have been linked to self-directed learning: “linear, interactive, and instructional” (Merriam and Caffarella 1999, p. 293). Dedicated discovery learning affects a minority of active learners who have low learning dependencies or need for supervision. Such discovery learners tend to be purposive and focused, self-disciplined, open-minded, and both strategic and tactical in the pursuit of knowledge and skills. The ability to engage in discovery learning may come with practice and maturity in adult learners. Discovery learners take initiative to set learning goals; scan the subject-domain environment; identify resources; create a strategy to acquire relevant information, experiences, and skills; assess their progress and revise strategies; and engage in short-term and long-term learning activities in a self-disciplined way. Long-term endeavors require grit and persistence, particularly for more complex achievements; they also require progressively greater challenges to maintain learner interest and creative flow. The new learning Scaffolding Discovery Learning Spaces may augment formal learning (for workplaces and institutions of higher education); it may be part of lifelong learning, self-enrichment learning, hobbies, entertainment, and other idiosyncratic interests. Discovery learning follows a general trajectory, which is nonlinear and recursive (Fig. 1). The first cause or inspiration for discovery learning may stem from any number of contexts. Discovery learners often frame their inquiry as a real or artificial problemsolving, informational needs, or curiosity-fulfilling endeavor. The work may begin with casual browsing and early probes into the topic. They set learning goals; they determine the standards for information relevance; It may begin with a simple question they set the schedule and pace of the learning. They may choose to partner and collaborate with others in this endeavor. They pursue learning experiences and information in a variety of environments (online, mixed-reality, and real spaces) and are rewarded with signs of progress and development. They may follow a structured process or an unstructured approach. They make decisions in this process of what resources and experiments and social interactions to pursue. Discovery learners vet the foraged data and judge them for veracity; they evaluate 2917 concepts for generalization and transference; they identify the far limits of analogies; they appraise processes for applicability to different situations. They apply the new information to their particular situations; they work on fresh insights. They coordinate their own discovery learning with a set of tools and resources that they are comfortable with, and they may develop and build new learning abilities. Some go farther and generate new knowledge and innovations. A rare few may evolve the learning into something of value for the larger society, knowledge structures, or markets. They engage their own metacognition to understand how they are learning, in order to self-regulate. Discovery learning may be applied in any of the various stages of skill development as conceptualized by H. Dreyfus (1982): novice, advanced beginner, competence, proficiency, and expertise. The aim of scaffolding is to build up discovery learners and their learning efficacy. How learners see themselves affects their level of initiative and risktaking in learning, so their sense of confidence and ability should be supported. They should have the proper information necessary to make the appropriate decisions for their own learning. They should have First Cause, Inspiration Value-Added Contributions to Society Generating New Knowledge and Innovations S Framing the Inquiry, Problem, or Project Early Probes, Casual Browsing A General Trajectory of Discovery Learning Application of New Learning to Context Levels of Expertise Evaluation of the Experiences, Information, and Learning Pursuing Learning Experiences (Subject Matter) Expertise Proficiency Competency Advanced Beginner Novice (Dreyfus, 1982) Partnering, Collaboration S Setting Learning Goals Determining Standards for Information Relevance Scheduling and Pacing the Learning Scaffolding Discovery Learning Spaces. Fig. 1 A general trajectory of discovery learning 2918 S Scaffolding Discovery Learning Spaces a clear sense of the progress they have made and the learning gaps that still exist – as well as the available learning resources. Higher education has long crossed the Rubicon of information technology (IT) integration and acceptance, and these added functionalities must be designed into scaffolding in face-to-face learning, online learning, mixed-reality, and real spaces. Pure discovery learning exists free-form and unstructured. Guided discovery learning involves minimal or weak support. Scaffolding refers to the support tools used to enhance learning for the outliers in a learning community – the novices and the experts. IT affordances enable guided discovery learning based on the realization that discoveries are not usually fully chance ones but benefit from purposive help, whether the scaffolding is structural, tool-based, artificial-intelligence-agent based, or human facilitated. For example, automated explanatory feedback is stronger for scaffolding learning than merely corrective feedback (Moreno 2004). While prior discovery learning has focused on bounded learning of developed fields of study, newer discovery learning now also involves generative learning, the surfacing of novel knowledge. This new focus means the promotion of open learning through serendipity, recombinant insights, chance encounters, stochastic (undeterministic) simulation modeling, free association, and accidental sagacity – based on a history of field-changing, paradigm-shifting changes based on unexpected learning. “Chaos” and ambiguity have been identified as necessary conditions in formulating insights, innovations, and entrepreneurial activities. Innovators must fully understand the current intellectual order but also challenge that order with new conceptualizations (Csikszentmihalyi 1996). A range of factors may affect the quality of the discovery learning, including human perceptual limitations, biases, selectivity, irrationality in response to cues (Kruschke 2003), and cognitive dissonance. To head off the risks of negative learning, discovery learners may benefit from support at various stages. The inferences learners make may amplify concepts and understandings, but they may also lead to dangerous misconceptions. If a full understanding of a particular field’s logic of discovery is not understood well, foundational gaps may be missing from learner mental models. The self-guiding of amateurs and novices provides plenty of risk for false discovery and wasted energies, time, and resources. Researchers have observed that even with contextual help and manuals, learners may end up in situations of unrecoverable errors. Scaffolding Discovery Learning Spaces The different types of scaffolds for discovery learning may be conceptualized as three main types: (1) structures/environments, (2) dedicated tools, and (3) virtual learning communities. Figure 2, General Types of Scaffolds for Discovery Learning, shows some of the elements that fit into these categories. Structures/Environments and Ecologies A scaffolded structure, environment, or ecology creates a space for discovery learning. These may involve discovery learners at various stages of their pursuit but often offer tools to help users frame their questions. These are built to create a sense of learning context often aligning with the particular domain. Supportive scaffolds involve advanced organizers which preface contents with schemas or outlines. Various learning elements may be unified into a cohesive space which structures time and the pacing of learning; sequential learning experiences, and sensory inputs. These spaces may bring together those with similar interests for live interactivity (such as through human-embodied avatars) and intercommunications (audio, video, textual, and other sensory-rich combinations). Immersive spaces offer a range of synthetic worlds, gaming spaces, and artificial life ecosystems for learner engagement and self-learning. Underlying these spaces are semi-hidden models of physics, natural worlds, and artificial lives – which in combination create complexity. These spaces are enhanced by the presence of other people in human-embodied avatars. Some role plays and simulations may be derived from hypothetical events with “meager” information – near-histories, scenarios (March et al. 1991, p. 4), which expand insights and the human imagination. Knowledge-based environments may structure the information with concept maps, ontologies, taxonomies, or node structures. These are ways that information are described, categorized, set in interrelationships, and represented visually. Information may be represented in the context of whole-part relationships and according to different levels of abstraction or granularity. Accurate semantics and metadata are critical for knowledge Scaffolding Discovery Learning Spaces Personalized feedback Advance organizers/outlines/concept mapping Knowledge structures/ontologies/taxonomies/node structures Search tools (with customization and serendipity) Executive discovery learning functions Self reflection and documentation tools Conceptualization tools Task sequencing/processes/procedures Pedagogical agentry and intelligent robots Institutional memory and reputation Rewards and reinforcements Smart and customized search tools Repeatability and review Priming and debriefing Simulations Modeling Designed cues Immersive and experiential learning 2919 Contextualized help Feedback loops Curriculum and study guides Framing the issues Defining the context/situation Introducing the domain Decision support tools S Decision support tools Structures/ environments Dedicated tools Intercommunications tools Virtual learning communities Icebreakers Trust building tools Dyadic partnering Group collaboration Reputation management (both individual and team) Pay and exchanges Multisensory intercommunications (asynchronous) Multisensory intercommunications (synchronous) Conceptualization tools Visualization tools Knowledge archival and selective dissemination/sharing Intellectual property protections Private/semi-public/public spaces Connections to larger societal resources for dissemination/ rewards Scaffolding Discovery Learning Spaces. Fig. 2 General types of scaffolds for discovery learning management. A knowledge domain involves learning about related terminology, theories and principles, history, biographies of contributors to the field, values and ethics, professional roles, professional practices, standards for new learning, applied decision-making and problem-solving, technologies, and other factors. Information may be understood as stand-alone or as part of a larger context or domain. Information may be raw and unstructured or processed and integrated with a larger construct. In knowledge environments, search is a central part of discovery through various text effective and accurate audio, visual, and computer-enhanced customization tools. People engage in different types of browsing: “opportunistic browsing” is intentional but without a particular goal in mind; “involuntary browsing” involves unintentional eye gazing, without even any latent goals; “search browsing” is intentional and goal directed (De Brujin and Spence 2008, pp. 5:3–5:4). Stimulated browsing may raise the breadth of what is searched and promote serendipitous discoveries. Scaffolded ecologies support novices by offering built-in extrinsic rewards (such as greater standing and resources in educational games) as encouragement for efforts; these rewards should be nuanced so as not to minimize intrinsic motivations. They may offer optin practices and interactive learning, along with rich explanatory feedback. The programmed learning may build off of swarm intelligence by offering unique learning sequences based on the learner’s profile and similar profiles of prior successful learners’ sequential experiences; powerful datamining and machine intelligence tools enable the capture of human experience to scaffold discovery learning for others. Performance-based branched learning may also be delivered in customized ways. Such systems strive to maintain learner interest. If the learning is too easy, learners may become bored; if the learning is too S 2920 S Scaffolding Discovery Learning Spaces difficult, learners may feel frustrated and anxious. Cognitive overload occurs when a learner has reached absorptive capacity. In real spaces, latitudes and longitudes may be geotagged and involve the delivery of digitized information and explorative augmented reality experiences. Digital installations may involve tangible smart devices and wearable computing to interact with a computerized system (White et al. 2007, p. 1); some even use natural human gestures as communications with a computer system, which uses cameras and image recognition for machine comprehension and feedback. Discovery learning environments may include task sequencing to support the learning process. These learning sequence strategies may be developmental, time-based, problem-solving/project-based, socially coordinated, or mixed methods (Hai-Jew 2008). These may maintain institutional memories of people’s contributions and unique individual and group reputations for past behaviors, achievements, and contributions, as in wikis and virtual learning environments. There may be tools to surface latent learning through reflection and thinking prompts. Learners may be able to repeat and review their online experiences. They may be able to access decision-support tools – whether these are delivered in the virtual environments or on hand-held devices in ubiquitous learning situations. Those who take part in immersive simulations, digital laboratories, and experiential models may also experience pre-immersion priming for specific prerequisite learning and then a debriefing afterward to reinforce the important learning. Lastly, such spaces need to be longitudinal and persistent for value, which means that they must exist in a perpetual state for learning value. These learning spaces may become part of learners’ lifelong learning endeavors, if the spaces may evolve with the learners’ needs. Dedicated Tools Dedicated tools may be loosely coupled and standalone, such as Web services delivered through cloud computing. Tools may also be tightly coupled with discovery learning systems. Socio-technical spaces and learning/course management systems often use contextualized help to enable users to access processes and mental models of various aspects of their tools. Games and automated learning sequences involve rich feedback loops. Automated online learning often uses curriculum and study guides to enhance the accessibility of the learning. Automated curriculums also offer feedback based on learner actions, and more sophisticated systems offer personalized feedback based on learner performance and profiling and stated preferences. Human help may be accessed through help desks that are usually available 24/7/365. Such tools may enhance the executive function of discovery learning – which involves scheduling and follow-through through calendaring and reminders, decision-making through workflows, and inspiration through new contents, live events, hedonic enjoyment, and digital game “hard fun.” Tools that respond to learners’ respective strengths and needs enhance their self-enthusiasm, which supports autonomous learning. Optimally, scaffolding should address learners “self-systems” in terms of how they approach the learning: the stable internal structures for that domain, mental models, sociocultural beliefs about the field, affective schemata, habitual behavioral patterns, and defensive routines. Self-reflection, conceptualization, and documentation tools enable learners to doodle, draw, sketch, write, think-aloud, journal, note-take, and create digital objects to express their ideas and thinking, in order to enhance deep learning. Some “modding” enables coding by learners to change their game and simulation experiences. They may express their own mental models of a particular knowledge domain and compare that against the conceptual models of experts. Discovery learners may locate and store relevant research as well as “encountered information” which may have future relevance (Marshall and Jones 2006). They may meet others with similar interests and collaborate around digital libraries and repositories and other knowledge structures. They may interact with pedagogical agents who work as guides or tutors through a knowledge space. Their work may be enhanced by machine-identified resources, some of which are tailored to the searcher’s preferences and behaviors (such as their degree of openness to following serendipitous links). They may use various assessments to get a sense of their level of learning, and they may access other types of decision-support tools to help them make critical choices at certain junctures. They may use various software programs to evaluate qualitative, quantitative, and mixed methods research – of the primary and raw Scaffolding Discovery Learning Spaces kind. Various tools may also provide back-end hidden information through datamining for a meta-perspective. The activity logs, the build-up of shared knowledge, and people’s behaviors in online and mixed-reality spaces may be captured in the “digital enclosures” (as suggested by M. Andrejevic in iSpy: Surveillance and Power in the Interactive Era) through various types of digital tracking and powerful computers with facial and voice recognition tools, and the use of protected personal information (PPI). Rich intercommunications tools and social networking sites enable global interconnectivity with others who may be helpful informants or collaborators. Virtual Learning Communities Virtual learning communities collaborate around shared topics and endeavors of interest. Members often share “symmetry of ignorance,” with co-learners all having a piece of knowledge but not the complete picture. In others, amateurs, novices, and subject matter experts all commingle, with fresh insights and shared guidance among them. Learning for novices often needs to be convergent (to particular “correct” answers); learning for subject matter experts often needs to be divergent (to lead to creative innovations). These human connections enhance boundaryspanning beyond the organizational limits of businesses, institutions of higher education, government agencies, and nonprofit organizations. These also mitigate cultural blindnesses (limits of observation and analysis based on social conventions) by offering a global range of wide scale participants with different viewpoints. Individual experiences are necessarily limited, so the exchange of relevant information broadens the participants’ insights. Such communities may encourage crowd-sourcing or referring to the larger public for knowledge. Scaffolding in virtual learning communities includes a range of tools. Expertise finder systems locate individuals with particular skill sets or knowledge. Back-end technologies may identify ad hoc virtual groups with shared interests and cyber affinities. Knowledge may be built more effectively in social groups, according to constructivist theory. With the popularity of social networking spaces, people may use these to express achievement, affiliation, and power. Rich intercommunication tools enhance human sociability through digital icebreakers and trust-building S 2921 tools (such as profiles and institutional memories of users’ past behaviors and contributions and popularity rankings). Telepresence (individual) and social presence (group) communicate live embodiment and actions in the digital space. The creation of both public and private spaces enables dyadic and group collaborations. Individuals and teams may influence their reputations through management tools. Payment and exchange devices may be deployed for freelance business arrangements. Multisensory intercommunications – both asynchronous and synchronous – enable individual and shared design and visualization. Mobile devices may deploy applications that show the users’ respective micro-blogs and real-time locations – to connect them to others with shared interests or from the same social networks. The archival of knowledge and group-created knowledge includes intellectual property protections and data integrity – for learner protections. The sanctity of private spaces must be protected for easeful work, and semiprivate spaces enhance select sharing among group members. Public spaces are needed to showcase the virtual community’s work and to help members connect with larger societal levers for work dissemination, credit, and rewards. The Usability Design of Scaffolds Present-day learners maintain high expectations that even complex socio-technical spaces and tools have intuitive user interfaces. These interfaces must bridge the so-called “gulf of execution” which exists between user understandings of what needs to be done to achieve a particular aim vs. what actually needs to be done. Some tools may be encapsulated and invisible to users (such as nuanced constraints to aid the learning or opaque underlying modeling for simulations and immersive experiential learning), and others need to be visible for opt-in usage. There is a fine balance between explicit and highly how intrusive recommender services should be to users and whether services should be solicited or unsolicited. Usable scaffolds will have to fit learners at their particular stage of needs. They have to be unobtrusive but accessible and functional when required. Scaffolds should “fall away” as they are not needed. They have to be customizable and adaptable to meet the unique needs of particular learners. They must add value by aligning with human perception, cognition, memory, analysis, and creativity. S 2922 S Scaffolding for Learning Important Scientific Research and Open Questions Scaffolding discovery learning spaces is a fairly new phenomenon, originating with the advent of information technology (IT) popularization in higher education in the 1990s and then the building of the semantic Web and social networking technologies that have enabled varied types of self-learning.

Scaffolding is a sustained interactive process that involves the fading of assistance/gradual task modifications by an expert. It is informed by nature of the context, task requirements, and the learners’ interest, strengths, and needs. Scaffolding should be distinguished from one-time forms of feedback and from programmed scripts used to prompt learners. Theoretical Background Wood et al. (1976) first used the term “scaffolding” to describe a tutor’s support of a tutee working with a puzzle: an exchange between a more knowledgeable other and a less knowledgeable other to support learning. Wood et al. (1976) described scaffolding instructional as interactive and developmental; a support intended to promote learner autonomy, involving the gradual reduction of expert guidance over time. Meyer (1993) extended the use of the scaffolding metaphor to encompass classroom structure and practice. She identified “three theoretical tenants” of scaffolding that suggest that the process of scaffolding requires the teacher (or person doing the scaffolding) to appreciate learner knowledge and its development as a constructivist process that is influenced by context and evolves through interaction. Kao and Lehman (1996) further extended the scaffolding construct to include facilitative tools and skills that enable learners to perform beyond their present capacities. Central to each of the above discussions of scaffolding is the reciprocal and evolutionary/iterative nature of expert-learner interaction(s). Further, these scaffolding interactions change in relation to the learning context and task as well as to the learner’s interests, strengths, and needs. The term scaffolding, however, is frequently, and inappropriately, applied to any form of verbal interaction that is undertaken with learning as a goal. Scaffolding should be distinguished from feedback that is a one-time, discrete directive or a hardwired script intended to enhance performance. Scaffolding constitutes an ongoing process of providing feedback with the goal of supporting learning. S Discussions about the provision of scaffolding typically reference Vygotsky’s (1978) Zone of Proximal Development (ZPD). A learner’s ZPD is the theoretical zone within which he or she can be supported to engage particular content; where one end point of the ZPD is the point at which the learner is currently able to complete the task independently and the other end point of the ZPD is his or her capacities when provided with support. The process of providing scaffolding then can be described as the expert’s adjustment of his or her interactions within the learner’s ZPD such that the learner becomes increasingly able to work independently. Stone (1998) describes the provision of scaffolding as having four key features: the task and nature of the supports that enable the learner to become involved in the task; the learner’s present capacity to engage the task; the range of supports offered; and the assumption that the provision of scaffolding will be temporary. When effective, scaffolding enables independent activity (Granott 2005); it stretches the learner to think, develop principled knowledge, and ask questions (Tabak 2004). Several distinctions for considering types of scaffolding have been suggested. Granott (2005) described the process of effective scaffolding as including both vertical variability (where the expert continuously adjusts his or her support in order to promote independent activity) and horizontal variability (where the expert shifts strategies if his or her initial efforts to scaffold are ignored or misunderstood). Brush and Saye (2002) distinguished between soft and hard formats of scaffolding. Soft scaffolds describe supports evolving from purposeful interactions wherein the provider of scaffolding diagnoses students’ needs and provides individualized and timely support. Hard scaffolds describe scaffolding that is built into curricular design (e.g., the requirement to respond in writing to feedback). Soft scaffolds are dynamic, situation-specific aides provided by a teacher or peer that can be implemented in both real-time and online (e.g., experts providing scaffolding feedback to learners remotely). Hard scaffolds, in contrast, are static supports that can be anticipated and planned in advance based upon the expected needs of learners working with a task. They can be embedded within classroom instructional practices or in multimedia and hypermedia software to provide support to learners at differing points of entry. 2923 S 2924 S Scaffolding for Learning Hannafin et al. (1999) categorized types of scaffolds as including: (1) contextual, providing hints or prompts; (2) metacognitive, providing specific support for the particular task; (3) procedural, providing support for resources that could aid task completion; and (4) strategic, providing different techniques or models. Hadwin and Winne (2001) further distinguished between tacit, or implicit, scaffolds and explicit scaffolds in order to suggest how scaffolding can support the development of self-regulation. Tacit scaffolds refer to embedded tools that serve to draw students’ attention to their learning behaviors without explicitly instructing them on task completion through four phases: task understanding, goal setting, metacognitive monitoring, and metacognitive evaluation and adaption. In contrast, explicit scaffolds provide direct instruction to students about how to improve their learning and strategies for working with the tools provided and afford students opportunities to request additional support. Just as interactions in the classroom may involve one or more types of scaffolding that are sequenced and made tacit or explicit according to learner needs and contextual factors, multimedia and hypermedia environments are designed to include multiple scaffolds that can be made more or less explicit. The scope and effectiveness of scaffolding differs if the learner is engaged in a one-on-one tutoring context, in a classroom that rarely allows for individualized interactions, or working with software that gradually guides him or her through a task (Davis and Miyake 2004). While it might appear that the multimedia and hypermedia environments are best equipped to provide the individualized support and iterative adjustment that scaffolding requires, many learners are not ready to work independently with these tools and require at least initial support to do so (Azevedo et al. 2005). Further, multimedia and hypermedia are typically limited in the interactions and iterations of support that they can provide learners. In these contexts, the process of scaffolding involves the gradual modification of a task, or restructuring of a problem, in order to increase accessibility. The emphasis is on task modification, or task parameters, rather than the learner’s solution procedure – meaning that the process of scaffolding is not likely to require the learner to modify his or her strategies in the process of acquiring the skill or concept, nor does it necessitate the kind of reflection and consolidation of information that would facilitate in transfer (Quintana et al. 2004). Important Scientific Research and Open Questions What is the most effective way to provide scaffolding that will result in reflection and transfer? For the practitioner and the researcher, the answer to this question also involves answering questions such as: ● What are the goals for scaffolding? For the learner? For the experienced other? ● What are the parameters of the task being scaffolded? ● How do task parameters support engagement – for whom and when? ● How do each of the identified distinctions in types of scaffolding impact learning? In Bruner’s (1990) description of scaffolding, the “teacher” or “parent” assumes a role in supporting the learner not only through task completion, but also through the process of valuing, engaging, and setting goals for working with the task. Although much of the research on scaffolding has focused on supporting selfregulation, provision of scaffolding involves not only supporting the skills necessary to engage the content of the task but also the support of student interest and engagement (Azevedo et al. 2005; Hadwin and Winne 2001). Discussions of scaffolding have stressed that the learner needs to be the focus of the interaction. It appears that learner characteristics that may determine students’ scaffolding needs and preferences merit further examination. There is evidence that learners’ abilities to work with different types of feedback is dependent on their phase of interest. Feedback offered to learners in an earlier phase of interest would be understood differently by learners in later phases of interest because of differences in knowledge and feelings about and value for the task (Lipstein and Renninger 2007; Sansone 1986). Differences in phases of interest impact students’ conceptualization of the task, questions, learners’ wants and needs for feedback, and self-regulatory skills (Renninger 2010). Scaffolding for Learning Phase of interest may also determine the scaffolding learners may need. In earlier phases of interest development, when the goals, knowledge, and value for the task are less developed, the learner needs scaffolding to provide what Azevedo et al. (2005) term regulatory support to engage. Once the learner is engaged, and in a later phase of interest development, he or she can be expected to self-regulate: asking questions, seeking and reflecting on answers. In later phases of interest, effective scaffolding will change to support the learner to reflect on and think about the content of the task and engage in meta-cognitive assessment and adaption (as opposed to simply encouraging engagement) (Renninger 2010). The following questions need to be considered as next steps for research and practice: ● How is the learner in earlier and later phases of interest positioned to respond to scaffolding? What are the contributions of the learner’s sociocultural context, age- and experience-related stages of development, their epistemic beliefs about a given domain? ● What does the person providing scaffolding and/or the software designer need to know or find out about the learner in order to provide effective scaffolding? How can this information be acquired? ● How can scaffolding provide support to both selfregulate and engage and also to work with task content? Does this type of scaffolding vary depending on whether it is occurring in person or online?

Scaffolding Learning by the Use of Visual Representations ILONCA HARDY1, SUSANNE KOERBER2 1 Department of Education, Goethe-University Frankfurt, Frankfurt, Germany 2 Department of Psychology, University of Education Freiburg, Freiburg, Germany Synonyms Theoretical Background In this entry, we will focus on instructional uses of visual representations within the fields of mathematics and science learning that are motivated by socioconstructivist views of learning. There is a broad literature on the use of visual representations within multimedia learning, which will not be considered in detail. Distinguishing characteristics of visual representations. Within the broad category of external representations we can distinguish between descriptions (written language/symbols) and depictions, with depictions further subdivided into visual-spatial depictions (manipulatives such as a balance beam) and visual-graphical depictions (i.e., realistic pictures such as photographs, analogical pictures such as use of realistic elements in metaphorical intention, and logical pictures such as graphs and diagrams; Schnotz 1992), see Fig. 1. These forms of external representation differ with respect to their mode of visualization, affecting their effectiveness (representational power). Both realistic pictures and analogical pictures display a given concept in a rather iconic way whereas logical pictures are not characterized by this visual similarity (iconicity) with the depicted situation; rather, they are based on arbitrary, context- independent representations and conventions. This more abstract mode of visualization allows the representation of elements and structures across a variety of domains, thus increasing representational power. Within the last years, visual-graphical representations increasingly gained attention in educational research because they combine the advantages of depictions and descriptions: visualizing concepts in a context-independent way – they offer a wide range of possibilities to display qualitative and quantitative information; exploiting spatial relations for displaying Graphical representation; Model; Scientific inscription; Visual display external representations Definition Visual representations are depictions that use space to represent nonspatial concepts, offering a wide range of possibilities to display qualitative and quantitative information in scientific contexts. Due to their facilitation of information processing, their support of knowledge construction, and their modeling of expert reasoning, they are employed as means of scaffolding in instructional contexts. depictional visual-spatial manipulative descriptional visual-graphical realistic analogical logical Scaffolding Learning by the Use of Visual Representations.

Instructional uses of visual representations. An important goal of science and mathematics education is students’ familiarization with discipline norms of reasoning and argumentation. Models and representations are one of these widely employed tools by experts. In the perspective of modeling science, the construction of conceptual knowledge is regarded as closely tied to modeling practices within meaningful contexts (Lehrer and Schauble 2003). Modeling here refers to students’ identification of variables and their interrelations in a given system, their synthesis as well as their (empirical) validation. Thus, the process of modeling is inherently tied to the use of external representations and artifacts, allowing the construction and negotiation of multiple points of view. Using external representations in complex and authentic settings, students will be familiarized with a scientific cycle where multiple explanatory models are contrasted in a search of alternative explanations. A further instructional goal of representational activities concerns students’ ability to make sense of different forms of conventional and selfdesigned representation. Here, students need to be attuned to different ways of expressing structural relationships – a competence that has also been called metarepresentational (diSessa 2004). To this end, visual representations in instruction should ideally (1) scaffold the process of reasoning, (2) support studentinitiated conceptual understanding, and (3) allow the transfer between multiple forms of representation. Mechanisms of scaffolding. For meaningful learning to take place, students need to actively access relevant prior knowledge and to relate this knowledge to the problem at hand to create a mental model. Elements of scaffolding are meant to support this process of meaning making. The functioning of scaffolding has been described by the mechanisms of focusing and modeling (Pea 2004). While focusing reduces the complexity of a task, for example, by reducing the degrees of freedom during problem solution, modeling situates a problem within a broader disciplinary context. This may be achieved by modeling expert solution processes and reasoning, thereby producing a discrepancy between current student conceptions and discipline norms. Visual representations fulfill these two functions of scaffolds. In the function of focusing, they make salient S 2927 relevant quantities and relationships between constructs while other (irrelevant) variables are not represented. For example, in a Cartesian graph we may represent the density of an object as the proportional relation between mass and volume, while the characteristics of form or surface structure (which are commonly associated with an object’s floating and sinking in naı̈ve conceptions) are not considered. The visualization of quantities therefore provides an attentional focus to students that reduces the salience of objects less central to the construct under consideration. In their function of modeling, visual representations may be regarded as ways of familiarizing students with disciplinary norms of reasoning, thus modeling more advanced conceptualizations. For example, a Cartesian graph may support students’ realization of the multiplicative strategy in proportional reasoning when students are confronted with a discrepancy between their (inadequate) additive conceptualization of ratios and their construction of a slope conveying the same concepts in a multiplicative relation. This way, students may come to be dissatisfied with their existing knowledge, one important precondition for conceptual change. Beyond experiencing a discrepancy, students are also provided with a model of more advanced reasoning with proportional concepts when using a Cartesian graph. Important Scientific Research and Open Questions There are three main strands of research regarding students’ uses of visual representations, focusing on the developmental prerequisites and stages of graph comprehension, the cognitive effects of visual representations in text comprehension, and the instructional uses of visual representations especially in the fields of mathematics and science. Developmental research. The developmental research on visual-graphical competencies is concerned with (1) early competencies with regard to the comprehension of graphical conventions and (2) natural constraints of graph uses due to internal mapping mechanisms. It has been found that already 4-yearolds are able to acquire rules for the interpretation of conventional graphs and are able to use information of bar diagrams to solve simple arithmetic problems. This ability increases with age from more qualitative to quantitative uses of bar graphs. Similar evidence S 2928 S Scaffolding Learning by the Use of Visual Representations of early competencies has been found for the interpretation of covariation data. Generally, children from preschool age to elementary school age develop the capability to differentiate between relevant and irrelevant attributes of an external representation. For example, a child comes to understand that the color used to represent a street in a map does not correspond to the color of the street in reality. Despite positive findings on early competencies, there is also evidence on persisting misconceptions on graphs even in secondary school. In order to be classified as competent representational users, students should have at least acquired a form of “correspondence mastery” where they are capable to (explicitly) refer to the mapping conventions and conventions of interpretation when using an external representation. A controversy concerns the degree to which children access a form of privileged knowledge when interpreting graphs. In the hypothesis of a “structural similarity constraint,” it is postulated that children are endowed with a structurally sensitive mapping mechanism from nonspatial concepts to spatial concepts, where conceptual elements are mapped onto spatial elements, conceptual relations are mapped onto spatial relations, and secondorder conceptual relations onto second-order spatial relations. This constraint would help explain both early competencies of graph comprehension and the occurrence of instructionally resistant misconceptions of graph interpretation in cases where intuitive mapping mechanisms are violated. Cognitive research. In the cognitive research on the use of visual representations, the effects of different modes of presentation (text/text plus picture, animated/static, etc.) are compared with regard to different learning outcomes. In the so-called multimedia principle, it has been established that learners improve in achievement especially when verbal and pictorial information is presented in a coordinated way. This can be explained by the dual coding and processing of information, where the visual system allows a more efficient processing of spatial information and images than the verbal system. Also, the effects of cognitive load on learners, having to deal with information and procedures more or less central to task solution, have been established in this strand of research. It has been found that individual differences play a critical role in learning from visual representations. For example, learners with lower spatial ability (especially female students) may compensate their deficiencies by working with animated displays. Also, the degree of prior knowledge impacts the way in which a learner can profit from a given visual display. Finally, the effects of visual representations and animations differ according to their function in the learning process (representational versus decorational) and the content to be learned. These differential effects have led to a variety of methodical interventions with regard to the prompting of cognitive and metacognitive processing of information in computer-supported learning environments (Höffler and Leutner 2007). Educational research. The educational research on the use of visual representations is concerned with instructional methods facilitating student understanding of conceptual content with conventional and student-constructed external representations, usually based on a socio-constructivist view of learning. For example, it is investigated whether it is better to provide students with conventional representations or to have them construct their own forms of representation. Here, experience-near forms of representation may be distinguished from experience-distant forms, differing in the degree to which rules of construction and interpretation need to be established explicitly in instruction. Since students’ naı̈ve conceptions usually only permit the incomplete representation of a situation, most student-designed representations at first will be missing some of the scientifically relevant quantities and structures. Also, the interpretability of studentsdesigned representations for other students will be constrained by idiosyncratic ways of representation. Therefore, the teacher needs to find forms of adequate support during the process of model construction and the collective negotiation of meaning such as specific cognitive and metacognitive prompting. In the long run, modeling activities can be considered helpful only if a representation’s idiosyncratic character is given up in favor of expressing scientifically correct quantities and relations. This may be achieved in classroom discussions where norms of representing are negotiated – a process which moves a representation from a “model of ” (a given situation) to a “model for” (scientific reasoning), see Gravemeijer et al. (2002). Overall, teachers need to know about their students’ cognitive prerequisites with regard to the processing of visual information, they need to know about the Schedules of Reinforcement specific effects of different forms of visual displays, and they need to settle their specific uses of representation within an instructional theory of modeling. As is often the case, the three strands of research have developed rather independently so that theoretical views are rarely transferred between them. Especially with regard to the development of students’ visual-graphical competencies within complex instructional settings, it will become necessary to tackle issues such as the mechanisms of development and processing with different theoretical lenses in order to allow instructionally adequate interventions at an individual and group level.

Scenario-Based Learning ▶ Action-Based Learning Scene Understanding ▶ Model-Based Scene Interpretation by Multilayered Context Information Schedules of Reinforcement KENNON A. LATTAL Department of Psychology, West Virginia University, Morgantown, WV, USA Synonyms Contingencies of reinforcement; Operant behavior; Operant conditioning; Positive reinforcement; Negative reinforcement Definition Schedules of reinforcement are procedures for arranging reinforcers in time and in relation to responses. Theoretical Background As tools for the study and change of behavior, they are widely used in both basic and applied research in psychology and in application. Procedurally, they are the wellspring of individual-subject research designs in psychology. Conceptually, they are fundamental in understanding the role that the environment plays in controlling behavior. Practically, they are ubiquitous in the everyday life of all living organisms. S 2930 S Schedules of Reinforcement History: Schedules were discovered by B. F. Skinner in his earliest experimental analyses of behavior. In one experiment he “decided to reinforce a response only once a minute and to allow all other responses to go unreinforced” (1956, p. 226). The result was a periodic (or, later, a fixed-interval) schedule. By varying the response requirement in a study of the relation between it and deprivation, he subsequently discovered the fixed-ratio schedule. These two schedules generated different patterns of responding, and in turn led to discoveries of numerous other schedules and combinations of schedules, many of which are summarized by Ferster and Skinner (1957). The taxonomy of reinforcement schedules developed by Ferster and Skinner (1957) is the standard description in most behavioral research. A different taxonomic system, based strictly on temporal variables, was proposed by Schoenfeld and Cole (1972), and received some use in earlier times, but it is rarely used today. Mechner (1959) proposed a flexible system for diagramming and describing reinforcement schedules that was the basis for developing a widely used computer programming system for arranging reinforcement schedules. Reinforcement: Reinforcers are stimuli or other events that, when made dependent on a response, develop or maintain that response as a result of either their presentation (positive reinforcement) or removal (negative reinforcement). The critical procedural feature of reinforcement is the dependency between the response and reinforcer. Reinforcers can be scheduled in the absence of a response-reinforcer dependency, at either fixed or variable times since the previous reinforcer. Under these conditions, responding can develop, but often it is idiosyncratic and unstable. Indeed, delivering response-independent reinforcers has been shown to be an effective means of reducing problem behavior. Arranging schedules of reinforcement: Schedules embed the basic response-reinforcer dependency that is critical in the reinforcement process in a broader temporal and response-requirement context. Reinforcers can be scheduled after a number of responses have occurred or after a single response has occurred and a predetermined period of time (an interreinforcer interval or IRI) has passed. The former describe ratio schedules and the latter, interval schedules. In addition, response requirements and time periods may be fixed or variable, which, combined with the time or response requirements yields a 2  2 matrix defining four basic schedules: fixed- and variable-interval (FI and VI) and fixed- and variable-ratio (FR and VR). Reinforcement also can be scheduled dependent on sequences of responses. Reinforcing two responses that occur within a certain time of one another is sometimes called an interresponse time (IRT) reinforcement schedule. If two responses are reinforced only if they are less than t seconds from one another, it is an IRT < t schedule, and if they are reinforced only if they are at least t seconds apart, it is an IRT > t schedule. These schedules also sometimes are labeled, respectively, differential-reinforcement-of- high (or low)rate (DRH or DRL). The schedules described above have been combined in other ways, suitable for studying specific research and applied problems. Two or more single schedules can be alternated, either in the presence of the same (a mixed schedule) or different (a multiple schedule) discriminative stimuli; made available at the same time (a concurrent schedule); arranged sequentially (one after the other) in the presence of the same (a tandem schedule) or different (a chained schedule) discriminative stimuli; arranged in an interdependent fashion such that the requirements of two or more schedules must be met for the response to be reinforced (a conjunctive schedule); or interconnected such that with both a time and a response requirement, responding changes the time requirement (an interlocking schedule). Other scheduling arrangements are possible, but the ones described in this section are the ones used most often in behavioral research to this time. From their inception until the advent of digital computers, schedules were restricted by technological limitations in their programming, which, in the beginning, was accomplished by electromechanical devices. With the advent of the digital computer, more complex scheduling arrangements became possible. For example, schedules have been arranged to reinforce specific patterns of responses as defined by a computer algorithm, such as linear, or positive or negatively accelerated responding across the interreinforcer interval (Hawkes and Shimp 1975). The analysis of such dynamic interactions between responding and its consequences, as enhanced by digital computer technology, is a logical extension of the more static arrangements that characterize earlier research on reinforcement schedules. Schedules of Reinforcement Important Scientific Research and Open Questions Effects of reinforcement schedules on behavior: Behavior typically conforms to the requirements of the reinforcement schedule, other things being equal. The cumulative response graphs in Fig. 1 illustrate the different rates and patterns of responding that are obtained from FI, FR, VI, VR, and Sidman avoidance schedules. The pattern of responding across individual FIs is described as positively accelerated; however, this pattern can change to a more bi-valued “break-andrun” pattern in the steady state. That is, after reinforcement there is a pause followed by a relatively high, steady response rate. The latter pattern also is common of FR schedules, in contrast to VI and VR schedules, which generate more evenly distributed responding in time (albeit at very different rates, with the VR controlling considerably higher rates). Schedules also may induce other forms of behavior, such as excessive drinking or aggression. Responding on mixed and tandem schedules is an amalgam of the responding maintained by the separate schedules, but multiple and chained schedules, because of the presence of the discriminative stimuli, maintain the characteristic performance appropriate to each of the component schedules. In concurrent schedules, the allocation of responding to the different choice alternatives depends on the schedules in effect (see entries 2931 Free-operant avoidance Responses The schedules described thus far in principle could be used with both positive and negative reinforcers; however, the predominance of research involving such schedules been with the former. The most frequently used schedules of negative reinforcement involve the postponement or deletion of scheduled aversive stimuli, such as brief electric shocks. The first such schedule was named Sidman avoidance in recognition of its creator (also called free-operant avoidance). In the presence of an environment without exteroceptive stimuli ever changing, each response postpones for a fixed, specified time an otherwise inevitable electric shock. Continued responding postpones shock indefinitely. Variations on Sidman avoidance schedules program shocks to be delivered at fixed or variable times from one another, and a single response within each intershock interval cancels the shock. As in Sidman avoidance, the exteroceptive stimuli are constant throughout each experimental session. S FI FR VI VR Time Schedules of Reinforcement. Fig. 1 Cumulative response graphs showing accumulated responses on the y-axis as a function of time on the x-axis under different schedules of reinforcement. The graphs are not on the same scale, so the number of responses and time depicted in each is indicated in parentheses in the following descriptions. Top: Free-operant or Sidman avoidance (1,000 responses/60 min). Bottom: FI (500 responses/18 min); FR (780 responses/10 min); VI (1,950 responses/20 min); and VR (1,050 responses/8.35 min). The vertical deflections on the top graph indicate shock deliveries and on the bottom graphs food presentations on ▶ Choice, ▶ Matching). When the choice is between VI schedules, reinforcement rate is a primary determinant of the time and responses allocated to either alternative. Research on schedules involving escape from aversive stimuli is insufficient to allow conclusions to be drawn about the functional similarities of positive and negative reinforcement schedules. Schedules arranging for aversive stimuli to be avoided or postponed control behavior efficiently, to the point that only a small proportion of the total number of possible negative reinforcers (aversive events) that could occur, actually S 2932 S Schedules of Reinforcement do occur. An example of the rather evenly spaced steady-state responding on a Sidman avoidance procedure also is shown in Fig. 1 (top graph). Responding on reinforcement schedules is affected by two types of variables: those imposed by the algorithm by which the schedule is programmed (labeled direct variables) and those that emerge from the interaction of the programmed schedule and behavior (labeled indirect variables). Direct variables include the nature of the response required (e.g., the force of the response); parameters of reinforcement such as its rate, magnitude, and immediacy after the response; and the degree of restriction of access to the reinforcer (e.g., whether the same reinforcer is available from other sources and for less cost). Indirect variables are variables such as the time between reinforcers under FR or VR schedules, the obtained delay (as compared to the programmed delay) between reinforcer delivery and the response that produces it when delays are unsignaled, and the actual interresponse time that is followed by reinforcement (unless it is an IRT schedule as noted above). Significance of schedules: Reinforcement schedules are foundational tools in behavioral research. In the laboratory, they serve as baselines for the study of a variety of behavioral processes. For example, two concurrently available chained schedules have been useful in the analysis of both conditioned reinforcement and foraging and other schedules underlie the analysis of economic concepts, choice, and decision making. Methodologically, research on schedules of reinforcement was largely responsible for the presence of single-subject research designs in psychology. Skinner’s early research was conducted largely in the experimental physiology laboratory of W. J. Crozier at Harvard University. Experimental physiology research typically involved repeated measurements using only a few subjects. Skinner’s schedules similarly involved the study of repetitive cycles of responding followed by reinforcement, replicated across sessions with a few subjects. This replication of schedule effects across sessions evolved into the use of schedules as baselines for studying other behavioral phenomena. As Skinner’s research on schedules of reinforcement began to permeate experimental psychology, many also adopted the single-subject research methods that were so integral to his research. Schedules of reinforcement are the basis of several single-case research designs commonly used in applied behavior analysis to assess the effects of interventions on enhancing constructive behavior (and thus reducing problem behavior). The alternating treatment and simultaneous treatment designs (Kazdin 1982), for example, derives from the multiple schedule; the changing-criterion design derives from schedules involving adjusting contingencies as a function of the organism’s behavior, and the “simultaneous availability of all conditions” treatment design (Kazdin) derives from the concurrent schedule. Schedules have significance beyond their utilitarian, methodological value. Morse and Kelleher (1977, p. 197) observed that “schedule control is the single most important property of operant behavior.” They are the fundamental determinants of behavior in two respects. First, other behavioral processes, such as punishment, conditioned reinforcement and punishment, and stimulus control, all involve the maintenance of behavior, which defines schedules of reinforcement. Second, the form and function of behavior derives from the organism’s history, which is to say from the ways in which reinforcement has been arranged – scheduled – in the past as well as in the present. Whenever behavior occurs, a schedule of reinforcement was and is present. Whether the subject matter is a single well-defined response or multielement behavioral repertoires of adult humans, schedules of reinforcement are responsible for shaping and maintaining the behavior. It is for these reasons that schedules of reinforcement are said to be ubiquitous.

SEEL Department of Education, University of Freiburg, Freiburg, Germany Synonyms Frame; Plan; Scheme; Script Definition The word schema comes from the Greek word “swήma” (skhēma), which means shape, or more generally, plan. The plural is “swήmata” (skhēmata). The term “schema” (plural: schemata [UK], or sometimes schemas [USA]) is used in the sciences of learning and cognition to designate a psychological construct that accounts for the molar forms of human knowledge. A schema represents the generic and abstract knowledge a person has acquired in the course of numerous individual experiences with objects, people, situations, and events. Schemas organize knowledge about specific stimulus domains and guide both the processing of new information and the retrieval of stored information. They can be viewed as structured expectations about people, situations, and events. Theoretical Background Some authors have argued (e.g., Neisser 1976) that all human knowledge – everything from knowledge about the form of the letter A to abstract knowledge about astrophysics or political ideologies – is organized by schemas. They facilitate the ▶ assimilation of new S information into knowledge structures. As soon as a schema can be activated, it runs automatically and regulates information processing in a “top-down” manner. This allows information to be processed very quickly, a function which is vital for humans as it enables them to adapt to their environment more quickly. However schema activation and schema construction are two different problems. While it is possible to activate existing schemata with a given topic, it does not necessarily follow that a learner can use this activated knowledge to develop new knowledge and skills. This can be achieved through the construction of mental models (i.e., a central means of ▶ accommodation). The concept of schemas has been a central theoretical concept of cognitive and developmental psychology for decades. From a historical perspective, the concept of schemas can be traced back to Plato, who elaborated the Greek doctrine of ideal types – such as the perfect circle that exists in the mind but which no one has ever seen. The German philosopher Immanuel Kant (1724–1804) further developed this notion and introduced the word schema to characterize innate structures which organize our world. Kant comprehends a “schema” (of a concept) in general as a “procedure of imagination which provides a concept with an image” (Kant, Critique of Pure Reason, 1781/1929 B, p. 179 f.). For example, he describes the “dog” schema as a mental pattern which “can delineate the figure of a four-footed animal in a general manner without limitation to any single determinate figure as experience or any possible image that I can represent in concreto.” Such perceptual schemas defined by means of particular codes of practice are necessary whenever concepts are applied to infinite processes and therefore cannot be determined through the designation of a finite sequence of exemplifying illustrations. This is called “schematism” and is described by Kant as “an art concealed in the depths of the human soul, whose real modes of activity nature is hardly likely ever to allow us to discover” (Kant 1781/ 1929, pp. A141–B181). Another German philosopher who used the term “schema” is Johann Gottlieb Fichte (1762–1814). Occasionally, he defines schema as the shape or form of an object. This corresponds to Kant’s schematism of empirical concepts. Sometimes Fichte also uses the term “schema” in the sense of a “compendium of a knowledge domain, proofing, order” when he speaks about a “schema of investigation.” 2933 S 2934 S Schema(s) Since Kant and Fichte, “schema” has become a technical term of philosophy and the philosophy of science that appears mostly in composite words, such as “▶ axiom schema,” “▶ definition schema,” or “action schema.” These different uses of “schema” are united by the idea that the option of an action or a procedure is contrasted with the corresponding realizations. Particular actions occur as realizations of an action schema. Wright defines action schemas in terms of generic acts and their realizations as individual acts. Another distinction is made between type (= action schema) and token (= realization). One and the same action event can refresh/activate different action schemas. Under the influence of Kant, German psychologists, such as Otto Selz (1913) and Karl Bühler (1918), applied the schema concept to the fields of productive thinking and cognitive development. In the UK, Bartlett (1932) used the term in his experiments on social psychology. “The War of the Ghosts” used in Bartlett’s experiments can be found in many textbooks on cognitive psychology. For the second half of the twentieth century, Jean Piaget (1897–1980) can probably be considered the most influential epistemologist and developmental psychologist. In his seminal work, the concept “schema” plays an important role. One of the central concerns of Piaget’s work was the development of schemas and their functions for ▶ equilibration. He suggested that children learn by using existing schemas that are accommodated or assimilated. Piaget also used the term “affective” or “emotional” schemas – not in contrast to cognitive schemas but rather as totalities of primarily affective responses and feelings that can be transferred to analogous situations (Eckblad 1981). The key theoretical development of schema theory was made in several fields, including linguistics, anthropology, psychology, and artificial intelligence. The heyday of schema theory was probably in the 1970s and 1980s as an outcome of the paradigm shift in psychology (the so-called cognitive revolution) in the 1960s that resulted in cognitive constructivism. Its central assertion is that the content which is available in memory at a given point in time is the product of a constructive process in which consciousness itself is first built up as awareness. Cognitive constructivism also posits that thinking is a process of operating with symbols which makes people capable of representing their subjective experiences, ideas, thoughts, and feelings. Research interest in this field thus concentrates on the question of how knowledge is represented. Since cognitive psychology deals with the relationship between learning and retaining, it is guided by the assumption that memory includes all of the knowledge a person has and represents past experiences in cognitive structures. These structures are referred to as “schemas” and are understood as the building blocks of a constructive concept of consciousness. Consequently, schema theorists (e.g., Mandler 1984) argue that schemas represent the generic and abstract knowledge a person has acquired through numerous individual experiences with objects, people, situations, and actions. The major assumptions of schema theory can be summarized as follows (Rumelhart et al. 1986): 1. Human knowledge about the world is represented in memory as the sum of structured units called schemas. 2. Most schemas are acquired through learning; however, some primitive schemas are assumed to be innate. 3. There are schemas of objects (e.g., a CHAIR schema), of persons (e.g., a TEACHER schema), of a state of affairs (e.g., a PEACE schema), of abstract concepts (e.g., a COMMUNISM schema), of relationships between objects (e.g., a RELATION: CHAIR-TABLE schema), etc. Schemas of actions and events are often labeled as scripts, a metaphorical use of the corresponding cinematic term. Furthermore, a distinction has been made between situational schemas (= “frames”), action schemas (= “plans”), and “grammars,” which represent the regular structure of narratives and stories (Mandler 1984). 4. Schemas are not direct, image-like copies of phenomena in the external world but the result of cognitive processing of information. The mind neither copies the world, passively accepting it as a readymade given, nor does it ignore the world. 5. Schemas have different levels of complexity and abstraction. One can have an abstract schema CHAIR as well as a concrete schema of one specific chair, for example, in a particular dining room. Schema(s) 6. Schemas have variables which can take on various values. The elements that make up a schema can be called slots. Any important element or schema within a schema may be thought of as a slot that can accept any of the range of values that are compatible with its associated schemata. For example, a very general schema for BUY may have four fairly abstract slots: a seller, a buyer, an object, and money. On different occasions these slots in the BUY schema will be filled differently. In one case the buyer will be a woman, in another a man, the object bought can be either a Hamburger or a book, etc., that is, the concrete slot fillers vary in different environments and situations but fit into the same schema BUY. 7. A schema can integrate new data into its organizational structure. It can put new information into the existing human database. 8. Schemas can embed with each other (e.g., CHAIR as a subschema of FURNITURE). This characteristic has to do with the abstract intensification of attributes and the hierarchical organization of schemas of various generalization and abstraction resulting from this process. Schemas serve several cognitive functions, which can be characterized as integrating information, regulating attention, and making inferences. However, since Piaget the major cognitive function of schemata is seen in assimilation. Schemata provide learners with the cognitive framework for “matching” information from stimuli with content from knowledge memory, thus allowing them to select the information that is consistent with the schema. Anderson (1984, p. 5) captures the essence of these functions of schemas when he remarks: “Without a schema to which an event can be assimilated, learning is slow and uncertain.” Types of cognitive schemas are as follows: ● Social schemas are about general social knowledge. ● Person schemas are about the attributes (skills, com- petencies, values) of a particular individual. Person schemas often correspond with the personality which is attributed to a person. Idealized person schemas are called prototypes. This word, however, is also used for any generalized schema. ● Self-schemas are about the self. They are generalizations about the self abstracted from the present S 2935 situation and past experiences. Self-efficacy, for instance, is a type of self-schema that applies to a particular task. People also hold idealized or projected selves, or possible selves. ● Role schemas are about proper behaviors in given situations. Role schemas contain sets of role expectations on how an individual will occupy a certain role to behavior. They are used for various purposes, such as evaluation of others, role playing, identification of roles, and prediction of behaviors. ● Event schemas (or scripts) are about what happens in specific situations. Event schemas correspond with processes, practices, or ways in which people typically approach tasks and problems. They are the programs of action. Important Scientific Research and Open Questions The concept of a schema is sometimes so general that it raises and leaves many important questions. As a consequence, there are psychologists (e.g., Brown 1979) who reject the concept of schemas as unsuitable for theoretical purposes. Indeed, a major criticism of schema theories is that they are basically assimilation models (Brown 1979) which fail to answer questions on how existing conceptions are modified in the face of inconsistent input and how such theories deal with novelty. In cognitive psychology, schemas are defined as large-scale slot-filler structures that play critical roles in the interpretation of input data, the guiding of action, and the storage of knowledge in memory. Connectionist and PDP models, however, do not work with concepts such as schemas but rather conceptualize memory – consistent with recent brain research – by means of “▶ constraint networks” resulting from the sum of excitatory and inhibitory influences on a unit. Input comes into the cognitive system and activates a set of units which tend to act together as a response to certain patterns of the input. At a first glance, it does not seem possible to reconcile the concept of schemas with connectionist models of auto-associative memory, which posit that knowledge memory consists of a closely connected network of neuronal nodes, each of which includes a certain amount of activity. Knowledge is spread over the nodes and the connections between them and stored knowledge does not correspond directly to a schema. Obviously, connectionistic models refer to a completely different level of information processing S 2936 S Schema Development than the psychological conception of schemas: Connectionistic models study the microstructure of cognition whereas psychological constructs such as schemas refer to the comprehensive data structures which play a critical role in interpreting new information, regulating actions, and constructing knowledge and organizing it in memory. According to Rumelhart et al. (1986), however, this does not necessarily rule out the possibility that the concept of schemas corresponds to connectionist model approaches. These authors argue that schemata may be understood as characteristics of complex networks which are composed of many small neuronal cycles. These tightly interconnected units may correspond to what has been called a schema in cognitive psychology. “What is stored is a set of connection strengths which, when activated, have implicitly in them the ability to generate states that correspond to instantiated schemata” (Rumelhart et al. 1986, p. 21).

SEEL Department of Education, University of Freiburg, Freiburg, Germany Synonyms Acquisition of schemas; Construction of schemas; Formation of schemas Definition Schemas are acquired and constructed through experiences with specific instances. Physiologically speaking, they start as simple networks and develop into more complex structures. From the perspective of psychology, the development of schemas starts with the construction of simple behavioral action schemas, which are learned through organizational socialization and concrete experiences, and proceeds to cognitive schemas by means of the functional incorporation of the regular structure of actions into the memory. Cognitive schemas, such as scripts or frames, can be acquired either directly through a long-term process of learning and confirmation through repetition or indirectly through adaptation to stories, myths, films, movies, conversations, and role models. Theoretical Background The biological development of the brain initially causes the functions for perception and motor activities and their coordination to be developed in the cortex. Thus, the ideas which small children develop with regard to the world are dependent on their sensory and motor skills. In order to “grasp” the world in a very literal sense, small children develop sensory-motor or enactive or action schemas by repeating actions. Schema Development Actually, isolating a common deep structure from the manifold and various actions in the world is the essence of the “condensation” of more abstract schemas. Therefore, enactive or action schemas are the building blocks of sensory-motor intelligence and cognitive development. In Piaget’s epistemology, cognitive schemas are acquired and formed through a process of internalization conceived of as a functional incorporation of the regular structure of actions into the memory (Piaget 1954). Schemas are higher-level cognitive units that are acquired through slow learning. However, some primitive schemata are assumed to be innate. The gradual and lasting development of schemas is associated with processes of ▶ abstraction and ▶ generalization. Consequently, schemas have different levels of complexity and abstraction. Mature schemas are more extensive, more organized, more abstract, and contain more characteristics than less mature schemas. An important aspect of the organization of schemas is that simpler schemas can be “embedded” within more complex schemas. The development of schemas is a long process which requires many different kinds of learning experiences and is dependent on favorable conditions for psychological development. However, once a schema has been built up, it immediately and often unexpectedly begins to exert decisive influence on the acquisition of knowledge as well as on the spontaneous retrieval of attributes in defined memory traces. Information processing difficulties may occur when schemas S 2937 cannot be activated or matched with input information. In this case, schemas must be newly learned, revised, and/or replaced. Rumelhart and Norman (1978) suggest a classification of learning in terms of accretion, tuning, and restructuring of schemas. ● Accretion: It refers to the expansion of databases through the accumulation of new knowledge and the enlargement of cognitive structure. ● Tuning: A learner may use new information to “tune” an existing schema so it is more accurate, complete, or useful. ● Restructuring: A learner may use new information to reorganize or restructure a schema. If this is not possible or helpful, the learner has to construct a new schema or a mental model. These three modes of cognitive learning can be integrated into a cognitive architecture grounded on Piaget’s epistemology of equilibration and the interplay between assimilation and accommodation (see Fig. 1). Piaget (1954) argued that infants acquire knowledge of the world by repeatedly executing action schemas. This activity was assumed to be innately rewarding. Piaget introduced assimilation of new experience into extant schemas and accommodation of schemas to experiences that do not quite “fit” as the principal learning methods for infants. Schemas are defined as coherent slot-filler structures of the human mind that provide an individual with cognitive structures which allow a prompt interpretation of new information. If a schema does not fit S Accommodation Assimilation Accretion Schema modification Task problem Schema activation Tuning Reorganization Failure Success Success Mental model Failure Solution Revision Success Solution Schema Development. Fig. 1 Schema modification as the result of accommodation (Seel et al. 2009, p. 18) 2938 S Schema Development immediately with the requirements of a new task it can be adjusted to meet the new requirements by means of accretion, tuning, or reorganization. However, if accretion or tuning is not successful or if no schema is available, accommodation must take place in order to reorganize and structure an individual’s knowledge concerning the construction of a mental model. In general, accretion, tuning, and restructuring represent three modes of cognitive learning that have different implications for the status of a schema. However, new information can also have other effects on current knowledge, including two that are important for schema development: A learner may use new information to create and maintain ▶ cognitive dissonance. When new information does not fit with what is known, that information can be considered as an anomaly – something apparently real but presently incomprehensible. In this case, people activate their schemas to define what is “known” and then actively seek known anomalies in order to test and update the known. A learner may also use new information to clarify or increase his or her degree of certainty in a schema and thus confirm it. Important Scientific Research and Open Questions In cognitive and educational psychology, one can find the idea that schemas are stored in memory and can be activated whenever input information fits with their defaults. In the case of PDP models, however, schemas are conceived of as properties of entire neural networks rather than as single units or small circuits. Accordingly, schemas are not “things” and there is no representational object in the mind which is a schema (cf. Rumelhart et al. 1986). What is stored is a set of connection strengths which generate states that correspond to instantiated schemas. Schemas emerge at the moment they are needed from the interaction between large numbers of much simpler elements all working in concert with one another. In general, schemas are assumed to be “working models” composed of thematically related belief systems which are assembled during the entire course of life experiences. Beck defined a schema as “a structure for screening, coding, and evaluating the stimuli that impinge upon an organism . . . On the basis of the matrix of schemas, the individual is able to orient himself in relation to time and space and to categorize and interpret experiences in a meaningful way” (Beck 1967, p. 419). Developmental psychologists regularly emphasize the central role of early experiences in the formation of schemas, but cognitive-oriented psychotherapy argues that schemas may be modified at any time during life. However, the development of schemas is in general a lengthy process which requires many different kinds of learning experiences and is dependent on favorable conditions for cognitive development. However, at the moment we do not know how many repetitions of experiences with specific instances are necessary and sufficient for the development of a new schema. Another interesting question in current research on human cognition aims at determining the conditions under which a schema is revised, supplemented, replaced, or abandoned. Clearly, such changes are at the core of learning. When important schemas closely related to one’s sense of self (“core schemas”) are superseded or shattered, extreme confusion, suffering, and meaninglessness can result. This means that they evoke affects and emotions and constitute the fundamental basis of emotional schemas. Finally, since psychological work on schemas has come about quite separately from neurological or neuropsychological research, it becomes necessary to seek out parallels between the former and the latter in order to postulate a neuropsychological substrate for the schemas. On the one hand, cognitive psychology has focused on generating plausible models and then checking for experimental and, more rarely, neuropsychological viability. On the other hand, neuropsychological analysis of psychological constructs such as schemas has been limited due to insufficient methods and techniques of assessment as well as the tendency of neuropsychological research to focus upon “lower-order,” observable, or measurable brain processes. However, there have been some neuropsychological findings which have to some extent gone beyond the limits encountered by Piaget thanks to the development of new diagnostic and exploratory technology and methodology. These newer sorts of studies show “up-close” neuropsychological mechanisms which may well be implicated in the formation and maintenance of cognitive schemas. However, current understanding of the neurological substrate for intentionality, motivation, and consciousness suggests that such high-level Schema Therapy cognitive processes are not seated in any single area of the brain but rather seem to arise from complex feedback loops based on neural pathways linking numerous neuropsychological functions. Eigen and Schuster (1979) proposed a cyclic reaction scheme, termed ▶ hypercycle, in which each replicator would aid in the replication of the next one in a regulatory cycle closing in on itself. Hypercycles can be conceived of as dynamic patterns of energy which may play a role in the formation of schemas based on patterned tendencies built into the brain.

Schema Focused Cognitive Therapy ▶ Schema Therapy Schema; Schema focused cognitive therapy; Schema Focused Therapy (SFT); Schematherapy Definition Schema Therapy (ST) is an integrative psychotherapy approach that grew out of efforts to more effectively treat patients with personality disorders who had limited response or high relapse rates with other treatments. ST is based on an integration of insights from cognitive and experiential therapies and the theory and research in the areas of object relations, attachment, and developmental psychology into a system of therapy with a coherent conceptual model that translates readily into clinical practice. The major developer of the theory is Jeffrey Young, Ph.D. A key collaborator, Arnoud Arntz, Ph.D., is the leader of research to empirically validate this approach to treatment of personality disorder patients (Arntz and van Genderen 2009). In comparison with standard cognitive therapy, schema therapy probes more deeply into the childhood origins of distorted thinking, relies more on imagery and emotion-focused techniques, and is of somewhat longer term. The two major constructs differentiating it from other types of psychotherapy are schemas and modes of operation. The major stages of the therapy are (1) identification of major schemas and modes, (2) cognitive change work, (3) experiential change work, and S 2940 S Schema Therapy (4) breaking maladaptive behavioral patterns. The overall goal of the therapy is to develop the Healthy Adult mode of a person to meet their underlying needs in adaptive ways. The therapist attitude is one of high involvement and empathy. In ST terms, the therapist stance is described as “limited reparenting.” Applications of ST include the treatment of personality disorders including borderline personality disorder, Cluster C disorders, forensic populations, treatment-resistant depression, and couples therapy. ST can be administered individually or in a group setting (see separate entry for Group ST). Theoretical Background Schema therapy (ST) was developed conceptually in the late 1980s and early 1990s, a time when numerous investigators had training in both psychoanalytically derived models and cognitive behavioral therapies, and recognized the limitations of narrow approaches and were moving toward psychotherapy integration (Edwards and Arntz 2011). ST derives principally from Cognitive Therapy (established by Aaron Beck), attachment theory (particularly the work of John Bowlby), Gestalt therapy, and the idea that corrective emotional experiences are needed within therapy (Ferenczi and Alexander) (summarized in Edwards and Arntz, 2011). Maladaptive ▶ schemas are psychological constructs that include beliefs that we have about ourselves, the world, and other people which result from interactions of unmet core childhood needs, innate temperament, and early environment. They are comprised of memories, bodily sensations, emotions, and cognitions that originate in childhood and are elaborated through a person’s lifetime. These schemas often have an adaptive role in childhood (e.g., in terms of survival in an abusive situation it engenders more hope for a child if they believe they are defective as opposed to the adult). By adulthood, maladaptive schemas are inaccurate, dysfunctional, and limiting, but strongly held and frequently not in the person’s conscious awareness. Young (1990) identified 18 maladaptive schemas in patients with personality disorders that represent the following psychological constructs: I: Disconnection and rejection, II: Impaired autonomy and performance, III: Impaired limits, IV: Other-directedness, V: Over-vigilance and inhibition. A self-report questionnaire was developed to evaluate the strength of schemas endorsed – the Young Schema Questionnaire. An important development in ST was the addition of the concept of “modes of operation” or schema modes (Young et al. 2003). A schema mode is defined as the current emotional, cognitive, and behavioral state that a person is in. Dysfunctional modes occur when multiple maladaptive schemas are triggered. Generally speaking, four categories of modes are defined. Primary Child modes (e.g., vulnerable child, angry child) are said to develop when certain basic emotional needs (such as safety, nurturance, or autonomy) are not adequately met in a patient’s childhood. These “child modes” are defined by intense feelings, such as fear, helplessness, or rage and represent the innate reactions a child would have. Dysfunctional Parent modes such as Punitive Parent or Demanding Parent mode define the second category of modes. Dysfunctional Parent modes reflect the internalization of negative aspects of attachment figures (e.g., parents, teachers, and peers) during childhood and adolescence. When a patient is in a dysfunctional parent mode they experience self-devaluation, self-hatred, and/or they put extremely high pressure upon themselves. Dysfunctional coping modes, a third category of modes, are defined by an overuse of coping strategies such as overcompensation, avoidance, or surrender with a goal of protecting vulnerable modes from further pain. In a fourth category healthy modes, such as healthy adult mode or happy, joyful child mode, are found. The Healthy Adult mode includes functional thoughts and balanced behaviors, and the Happy Joyful Child mode is a resource for playful and enjoyable activities, especially in social networks. Modes are often triggered by events that patients experience as highly emotional. Modes can switch rapidly in patients suffering from severe personality disorders such as BPD, which results in sudden changes in behavior or seemingly disproportionate reactions. In general terms, the goal of schema therapy is to correct the maladaptive schemas via cognitive and experiential techniques and strengthen the healthy modes. A solid Healthy Adult is able to nurture and set limits with child modes, banish dysfunctional parent modes, replace the need for dysfunctional coping modes, has access to the Happy Child, and is able to function adaptively in the world and have a good quality of life. A self-report questionnaire, the Schema Mode Inventory, was developed by Schema Therapy Young and colleagues at the Schema Therapy Institute of New York and later tested and refined psychometrically by Arntz and Lobbestael. This questionnaire is a helpful therapy tool and is used in schema therapy outcome studies to assess decreases in maladaptive modes and increases in or strengthening of healthy modes. The therapist in ST must offer not only a collaborative adult relationship, as in standard cognitive therapy, but also a parenting relationship to the client’s child side. This is seen as necessary to correct dysfunctional schemas and to allow healthy new schemas to form in the context of a healthy reparenting relationship in therapy. According to Young (1990), this would involve finding out what basic emotional needs were not met in childhood and meeting them to a reasonable degree in therapy. The ST term “reparenting” describes the therapists’ caring attitude toward their clients and their acting as a “good parent” would early in therapy, in particular when dealing with the Child modes. In experiential work with the Vulnerable Child the therapist provides validation and nurturing within the bounds of a professional relationship. This position has been the source of some controversy and confusion. The basic position of ST is that patients who experienced depriving and/or abusive early caregivers must experience positive parenting before they can learn to do this for themselves. The goal of ST is autonomy, so this early focus on the therapist doing the reparenting is ultimately replaced by a developed and strengthened Healthy Adult mode of the patient. Reparenting targets the need of the mode the patient is in, so the Angry or Impulsive Child modes are provided with the empathic confrontation or limit-setting needed in those modes. The therapist in ST is also active in helping the patient replace maladaptive Coping modes like detachment with more adaptive coping and in assisting the patient in banishing the dysfunctional parent modes. This empathic, active involvement, and modeling by the therapist is termed “limited reparenting.” The cognitive techniques of ST are often familiar to those trained in cognitive therapy, and include monitoring thoughts, identifying distortions, examining evidence for and against a negative core belief, and reframing the belief. However, unlike many cognitive therapies, the therapist also assists the patient in linking distorted thoughts to the underlying maladaptive schema from the beginning of therapy. This enables a “bottom-up” approach in contrast to a “top-down” S 2941 approach focusing more on surface thoughts. A major innovation of ST in relation to CBT is the central place given to experiential techniques. These addressed a problem Young had identified – that clients in spite of working with rational analysis, changing negative thoughts and even experimenting with new behaviors, still failed to achieve change at the emotional level. Experiential techniques used in ST include imagery work, chair work, and mode dialogues in which the patient improves conscious access to various modes. Important Scientific Research and Open Questions Applications Schema therapy was originally developed to treat patients with personality disorders (PD) (particularly borderline and narcissistic PD) and treatment-resistant depression in an individual therapy setting. The effectiveness of ST for treating borderline personality disorder (BPD) was tested in a randomized controlled trial in the Netherlands led by Arnoud Arntz (Giesen-Bloo et al. 2006). In this trial, 2 years of individual ST was compared to the same amount of individual psychodynamic psychotherapy for patients with BPD. Patients in the ST arm showed improvement in all major domains of BPD symptoms, had higher retention rates, and were more likely to no longer meet the criteria for BPD by the end of the study. ST was also demonstrated to be significantly more cost effective than the comparator arm and therapists and patients reported higher satisfaction rates for ST compared to the psychodynamic comparator. An implementation trial conducted in general health care, also in the Netherlands, demonstrated similar effectiveness of individual ST for BPD. ST has also been tested with positive outcome in mixed personality disorders, cluster C personality disorders, and in forensic settings with patients with antisocial personality disorder. ST has been adapted for groups by Farrell and Shaw and tested in an RCT with BPD patients (Farrell et al. 2009). There is evidence to suggest that curative factors of groups may accelerate treatment effects and group delivery of treatment has the potential to make ST even more accessible and cost effective. A large international multisite RCT to further test the group model is underway led by Arntz and Farrell (see separate entry on Group ST). In various studies, many patients with S 2942 S Schema Therapy Group BPD feel that a schema therapy experience was “the first time I felt understood” and readily identify with the mode model that describes their own inner experience of rapid shifts in moods and behaviors. In additional clinical applications, ST has become popular with couples therapy, as patients find the concept of marital friction being worsened by cross-activation of various schemas and modes to be very helpful. Conclusion Schema therapy has become increasingly popular, reflected in its implementation in many clinical settings and the number of studies focusing on this particular type of therapy. Patients who have not responded to other therapy approaches often engage well to the warmth and empathy of the limited reparenting therapeutic stance, and relate to the user-friendly concepts and strategies utilized by ST. Future directions include additional empirical validation for the group STmodel; development of treatment and preventative work for children and adolescents at risk for personality disorders; trials testing the effectiveness of ST for eating disorders, substance disorders, and other conditions considered “difficult to treat.” Cross-References ▶ Cognitive-Behavioral Family Therapy ▶ Group Schema Therapy ▶ Maladaptive Schema(s) References Arntz, A., & van Genderen, H.

An SBA organizes these schemas in such a way so that action selection, motor coordination, and cognition in the general sense interact effectively. SBAs were mainly inspired by theories of ▶ sensorimotor adaptation and ▶ cognitive development and learning. Particularly ▶ Jean Piaget’s research on and theories of cognitive development in infants and children inspired the design of SBAs. ▶ Machine learning develops algorithms to learn, structure, and continuously adapt SBAs. Various forms of representations are used to develop SBAs, including symbolic representations, rule-based representations, as well as neural network representations. Theoretical Background Schema-based architectures have two main features. First, the computation is distributed among independent components (the schemas), in contrast to one centralized process. Second, SBAs encode a complete perception-action loop, in the sense that they include both perceptual and motor elements (plus, possibly, Schema-Based Architectures of Machine Learning internal representations). Thus, SBAs realize the control of a whole system. Due to these coordinated interactions of schemas, the success of an SBA not only depends on the quality of individual schemas but also on the quality of their coordination and their collective performance. Individual schemas in an SBA are specialized components that are responsible for a particular type of operation – such as the recognition of a specific feature (e.g., red) or of a specific class of objects (e.g., apples), the control of a particular action (e.g., grasping), or even the realization of sequences of perceptions or actions (e.g., a concatenation of reaching, grasping, and lifting an object). The coordination of schema interactions ensures that the schemas successfully cooperate in order to achieve complex behaviors beyond the abilities of individual schemas and, at the same time, that they effectively compete for the chance to be active. An SBA regulates the schema activities and thus determines which schemas take control of sensory processing and effector control. This feature of SBAs is usually referred to as cooperative competition (Arbib 2003). SBAs may be further classified into reactive SBAs, which consist of a collection of stimulus-action schemas, and anticipatory SBAs, which consist of a collection of action-effect and condition-action-effect schemas. The former class of schemas has been widely used in the realization of behavior-based architectures, in which reactivity is an essential feature that distinguishes them from traditional, symbolic, deliberative, and logic-based AI architectures. In these architectures, reactivity ensures quick responses to rapidly changing environments but it also reveals interesting emergent behaviors, which partially exceed the capabilities of traditional AI and robotic architectures. However, reactive architectures were found to be difficult to apply to more complex problems, which require additional capabilities such as, most notably, the ability to represent and reason about the future. Moreover, an increasing number of psychological experiments exhibit ▶ latent learning and generally ▶ anticipatory learning in animals – neither of which are possible with reactive architectures or reactive ▶ reinforcement learning principles. Thus, anticipatory SBAs take expected future states – be they action effects or other changes in the environment – into account for the determination of current schema activations. S 2943 Finally, SBAs may be classified into flat and hierarchical SBAs. In flat SBAs, sensory information is transferred into motor commands in a flat architecture without further abstractions. While the transfer process may still be reactive or anticipatory, there are no abstractions in the involved schemas in that higherlevel schemas may initiate or coordinate the activation of lower-level schemas. In hierarchical SBAs, such hierarchical schema interactions additionally enable the coordination of complex sequences of movements as well as the representation of more abstract concepts of perceptions and actions, such as something edible in contrast to a particular apple. Hierarchical architectures theoretically enable SBAs to realize more complex and flexible behavior patterns because current priorities and goals can be assigned to more abstract schemas, which in turn activate more concrete schemas dependent on the current availability in the environment. For example, a “hungry” SBA may activate the search for something edible, which may result in an apple being found. Next, that SBA may need to coordinate a consumption schema, which will first activate an appropriate grasping action, coordinated movements to the mouth and movements of the mouth, etc. Regardless of which type of SBA is used, the biggest challenge is to design or learn appropriate schema interactions. Each schema usually has an own-activity level, which is influenced by the interacting schemas as well as by the current sensory and motor activities. How these interactions are realized strongly depends on the particular SBA being used, the machine learning mechanisms involved, and the available representations, sensory perceptions, and motor activities. Important Scientific Research and Open Questions Various SBAs have been developed in machine learning. One of the pioneering systems in this field is Drescher’s (1991) schema architecture: a schemabased agent that operates in a simplified environment, with schemas having the form of action-effect rules. One interesting aspect of this architecture is that the agent is able to interactively enlarge its ontology by learning new synthetic items. If the system recognizes that there was a common cause of a set of related interactions, it postulates that an object caused this effect. For instance, if the agent recognizes that pushing left resulted in a stop, looking left resulted in seeing red, S 2944 S Schema-Based Architectures of Machine Learning etc., it postulates that a (red) object was in the left. Importantly, learning new synthetic items can be taken as a basis for the incremental construction of increasingly complex ontologies and behaviors, since the agent can then postulate new objects from a combination of old objects, and learn the effects of its actions upon them. Anticipatory learning classifier systems (ALCS) (Butz 2002) also develop sets of condition-action-effect rules. They are learned by means of combinations of statistical, evolutionary, and rule-based mechanisms and are based on the principle of anticipatory learning. Moreover, ALCSs include generalization capabilities in the learning mechanism so that overspecialized rules can be generalized to be applicable in a broader context. Generally, in ALCSs as well as in Drescher’s schema architecture a rule is activated given its condition is sufficiently satisfied. Once activated, it competes with other currently active rules. The SBA chooses the rule with the most promising effect based on the anticipated effects. Such effects may be chained to base action selection on priorities that lie even further in the future. The most promising action is executed and the process starts anew. Pezzulo and Calvi (2007) have proposed a schemabased architecture that uses the self-organizing principles of local activation (that is, schemas that transfer activation to each other) and global inhibition (that is, limited activation resources) for realizing cooperation and selection of schemas. Self-organizing neural networks are a good candidate to also shape hierarchical SBAs, but research in this direction is still in its infancy. It is particularly difficult to assess when a hierarchy should be established, since this decision may not only depend on the structure of the available perceptions, but also on the possible interactions with the environment as well as on the priorities of the system. Hierarchical reinforcement learning approaches may currently provide the best framework and most studies into the formation of such hierarchical SBAs – albeit mainly only in reactive architectures. Also neural network-base SBAs have been developed for the coordination of schemas. Particularly the forward-inverse framework of Wolpert and Kawato (1998) builds an interesting approach to schema activity coordination: each schema contains a neural forward model of action-dependent system changes. If the forward model of a schema fits well with the currently encountered changes, then it is also a good candidate to be activated for control. If additional current system priorities also favor the activation of this schema, its associated inverse controller may be activated. The extension of SBAs’ capability beyond the sensorimotor domain is certainly another crucial aspect of schema learning. One important example is to learn about other entities in the environment, since this knowledge constitutes one essential element of advanced conceptual abilities in humans and it can be associated with priorities and behaviorally relevant aspects, such as food, water, or mates. The detection and distinction of entities in the environment must thus be guided by machine learning methods that take into account internal rewards or priorities, external perceptual structures, as well as sensorimotor contingencies. Learning such concepts leads to a schema-based representation of affordances since schemas will associate entities directly with those interactions that are meaningful and possible. Another aspect of schema learning, beyond the sensorimotor domain, is the acquisition of linguistic and communicative abilities through schemas. Roy (2005) has proposed how sensorimotor and linguistic processes may be coordinated based on an SBA. First, representations of objects may be built based on encountered sensorimotor interactions with them and schemas may be associated to manipulate them. Later on, these schemas may be associated with linguistic representations of the same objects and interactions. Such an SBA thus integrates schemas that can recognize, manipulate, and linguistically refer to objects. How such an SBA may be learned with machine learning techniques remains one of the big challenges in the further development of SBAs in machine learning. In general, how hierarchical, anticipatory SBAs may be represented – most likely with probabilistic, Bayesian-based representations that associate schemas in various ways conditioned on current internal system priorities, current context, and current perceptions and motor activities – and how such representations may be learned rigorously (most likely with ▶ Bayesian learning, ▶ connectionist theories of learning, or ▶ association learning techniques) are highly challenging research questions, which still lead to much debate Schema-Based Instruction and controversy. In addition to the theoretical and methodological difficulties, one of the main challenges may lie in the definition of a sufficiently general problem setting that closely resembles natural problems. Once such SBAs are designed and improved by machine learning techniques, SBAs may yield even more power for the design and development of cognitive systems and robots. The resulting systems will not only be able to exploit and recombine their schemas to achieve their goals in (partially) novel environments and situations, but also to autonomously enlarge their basic schema repertoire by learning novel schemas at different hierarchical levels where necessary. These two processes are particularly relevant for schema learning, and correspond to the two main aspects of adaptation in ▶ Jean Piaget’s theory: Assimilation and Accommodation.

MARSHALL Department of Psychology, San Diego State University, San Diego, CA, USA Synonyms Problem solving; Visual representation Definition ▶ Schema-based instruction is a method of teaching problem solving that emphasizes both the semantic structure of the problem and its mathematical structure. It utilizes recognition of key words (as does a simple key-word strategy) but goes further than simple recognition to stress understanding of the situation represented in the problem. Theoretical Background Most schema-based instruction has targeted arithmetic word problems or algebra word problems. Research has shown that students have difficulty solving these problems for many reasons. A large number of errors can be traced to improper understanding of the problem itself, rather than inability to do the correct arithmetic. In the 1980s and 1990s, many psychological and mathematical educational researchers became interested in the basic cognitive issues required in problem solving (see ▶ schema-based problem solving) and began to investigate the importance of visual representation of a schema. Little research has been done on schema-based instruction and most of it to date focuses on problem S 2946 S Schema-Based Learning solving. At the heart of such instruction are graphical representations of the situations that may occur in problems (Chandler and Sweller 1991; Marshall 1995). These visual representations attempt to capture the basic relationships that exist in the problem and help students to construct mental models of the problem. For example, simple diagrams have been used successfully in a series of studies comparing traditional instruction with schema-based instruction for word problems at the third grade and ratios and proportions at the seventh grade (Jitendra et al. 2009; Griffin and Jitendra 2008). Students given schema-based instruction generally performed better than students with traditional instruction. Important Scientific Research and Open Questions Students in many fields (e.g., science, mathematics, and engineering) are encouraged to make visual representations of problems they encounter, but they often have no existing cognitive structures that help them do so. Schema-based instruction is designed to remedy this lack. Thus far, most formal schema-based instruction has been directed at elementary school mathematics. Further research is required to determine how well this method of instruction fares in more advanced arenas.

SEEL Department of Educational Science, University of Freiburg, Freiburg, Germany Synonyms Schema-Centered Learning; Schema-Oriented Learning Definition Schema-based learning is a central theoretical approach in cognitive and educational psychology as well as in artificial intelligence. Schemas allow learners to reason about unfamiliar learning situations and interpret these situations in terms of their generalized knowledge. In cognitive and educational psychology, schema-based learning is grounded in capturing and using expertgenerated schemas as frameworks for teaching and learning. Schemas can be learned to promote the acquisition of new scientific knowledge and skills. At the core of this approach is a generalization and abstraction method designed to extract and condense as much information as possible from a single example of successful task completion or problem solving. In the field of artificial intelligence, schema-based learning is conceived as a generalized framework for the design of integrated adaptive autonomous agents aiming at the incorporation of general principles of adaptive organization and coherence maximization. Schema-based learning allows the development of increasingly complex patterns of interaction between the agent and its environment by confining statistical estimation to a narrow criterion.

Schemas in problem solving. New York: Cambridge University Press. Schema-based learning builds on the schema theory. The theoretical assumption of schema-based learning is that newly gained knowledge is assimilated into preexisting knowledge and organized to form schemas. However, it is not enough to simply have a collection of passive schemas: one must also know how to use them. Anderson cites two types of situations involving schemas, namely: activation of preexisting schemas and construction of new schemas. However, Bransford (1984) points out that while it is possible to activate existing schemas with a given topic, this does not Schema-Based Learning necessarily mean that a learner can use this activated knowledge to develop new knowledge and skills. Accordingly, Bransford stresses the importance of helping learners to “activate various preexisting ‘packets’ of knowledge” and to “reassemble and construct this knowledge into an integrated new schema” (Bransford 1984, p. 264). Bransford and colleagues (1981) also argue that the new learning situation should help learners to fully understand the “significance of new facts” as it helps them to reorganize the previously unrelated facts in a more meaningful way. Schema-based learning emphasizes three issues: ● It is advantageous (efficient) to cope with new experiences on the basis of positive results from previous similar experiences. ● Schema-based learning allows incremental development of complex cognitive structures through aggregation from a restricted stock of schemas (i.e., stable units of composition) to more complex interactive structures. ● Schema-based learning provides the learner with instantiation, accretion, tuning, and reconstruction of knowledge. As a consequence, new schemas can be formed. At the heart of this approach is a generalization and abstraction method which is designed to extract and condense as much information as possible from single examples of successful task completion or problem solving. Essential constraints from integral parts of explanations of success must be incorporated into the results of generalization. There are two types of essential constraints: ● Internal-schema constraints connect component schemas together to form a complex schema. Technically, these are the assertions which support goal achievement by identifying parameters of instances of schematic forms with instances of ▶ prototypes. ● Intra-schema constraints ensure that each component of a complex schema is complete. Technically, these are the immediate supporters of the “self ” constraints which support the achievement of the goal. Optional constraints are “forced” or implied by essential constraints. They need not be included but should be. They do not alter generality but improve S efficiency. Technically, any assertion which has some justification depending purely on essential constraints is a member of this class. Extraneous constraints include most instantiation bindings and all implications based at least in part on extraneous constraints. Schema-based learning allows the development of increasingly complex patterns of interaction between the person (or an agent) and its environment by starting with a limited stock of simple schemas that allow efficient learning by confining statistical estimations of future events within the realm of a relatively narrow space. The literature on schema-based learning theories describes three types of learning: accretion, tuning, and cognitive restructuring (Rumelhart and Norman 1978). Research conducted in the area of cognitive restructuring is generally categorized under the heading of ▶ conceptual change. A traditional method used to facilitate conceptual change is to provide the learner with examples that contradict their “naı̈ve theories,” which is referred to as the anomalous data approach. Schema construction is a central element in schemabased learning. Learning is triggered when predictions made by anticipatory schemas do not match the observed results and the system does not reach the goal expectations. The dynamics of the system first try to reduce the error by tuning or accreting the current stock of schemas, and when this fails, a new schema must be constructed to remedy the error. In the long term, the reliability of the predictions will increase, making the system increasingly better at predicting the results of actions for a given context. In many cases, the agent will construct both a new schema and its corresponding predictive schema. Actually, most predictive/anticipatory schemas have to be learned by the agent through continuous interactions with the environment. In the field of informatics and artificial intelligence, schema-based learning is a data-driven, constructivist approach used to discover probabilistic action models within environments that serve as a generalized framework for designing integrated adaptive autonomous agents and predicting their actions by incorporating general principles of adaptive organization and coherence maximization (Corbacho 1998). A schema is defined as an experience-based recurrent pattern of interaction with the environment, and coherence is a measure of the congruence between the result of an interaction with the environment and the expectations the agent has for that interaction. 2947 S 2948 S Schema-Based Learning Schema learning comprises two basic phases: discovery, in which context-free action/result schemas are found, and refinement, in which context is added to increase reliability. Important Scientific Research and Open Questions In cognitive and educational psychology, schema-based learning is grounded on the concept of equilibration in Piaget’s epistemology. According to Piaget, equilibration involves both assimilation and accommodation. During each stage of development, people conduct themselves with certain logical internal mental structures that allow them to make adequate sense of the world. When the newly learned information packet does not match with the learner’s existing internal mental structures (existing schema), equilibration helps the learner to make sense of the world around him by assimilating new information into pre-existing mental schemes and accommodating it when necessary through logical thinking. This internal mental process enables the learner to construct more sophisticated schemas, which in turn leads to cognitive development. Pascual-Leone retained Piaget’s view of the human cognitive process as a highly dynamic and self-reflective system which passes through stages of stability and disequilibrium in the course of cognitive development. Pascual-Leone and Goodman (1979) distinguish several operators which are involved in the construction of new knowledge based on the assumption that the construction of new knowledge can be understood as a process of mental representation of environmental patterns. This process is strongly influenced by existing assimilative schemas. Accordingly, field forces compete with operators to determine which of the many schemas will be activated to regulate the processing of new information. During the course of processing, the activated schemas are enriched or restructured by internal operators. Pascual-Leone and Goodman distinguish between L-operators, which represent former learning experiences, A-operators, which represent emotional and affective side-effects, and Boperators, which represent stable personality traits. Finally, they add an M-operator, a moderator for using information processing capacity gained during development. Ausubel’s theory of meaningful learning (1968) is also meant to help students activate their pre-existing knowledge so that it can be assimilated, tuned, and restructured into new schemas. Hence, Ausubel introduced the theory of “advance organizers” to support the learner’s pre-existing knowledge. Advance organizers can help learners to activate schemas more effectively and allow them to use their pre-existing knowledge in a more effective manner. However, Bransford (1984) argues that advance organizers should be written differently depending on whether they are to be used for schema activation or schema construction. He states that an advance organizer can be effective if the learner has already acquired the necessary schemas for the given problem. However, it will not be of much help for schema construction. Bruner’s (1966) cognitive structure (i.e., schema, mental models) is consistent with schema-based learning in that it describes learning as an active process in which learners construct new ideas or concepts based on their existing knowledge. The learner does not passively respond to stimuli but actively selects and transforms information, constructs hypotheses, and makes decisions based on his or her cognitive structure. Bruner asserts that the cognitive structure supports the learner, actively generates meaning for real-world experiences, and allows the individual to process information in a meaningful way. He emphasizes that the learning situation should help learners to actively reorganize the new information, allowing them to build on existing knowledge in a meaningful way and use the newly gained meaningful knowledge effectively in the future. Wittrock’s concept of generative learning asserts that the learner actively constructs the whole process of learning. Wittrock (1991) states with regard to the generative model that “learners must construct between stored knowledge, memories of experience, and new information for comprehension to occur.” Accordingly, an important aspect of generative teaching is knowing learners’ preconceptions, how to modify these preconceptions, and how to induce them to generate a new model of the phenomenon by revising or transforming their models (Wittrock 1991). Cognitive load theory assumes that learning consists primarily of the acquisition of schemas. Sweller (1988) understands schemas as the cognitive structures that compose an individual’s knowledge. Learning requires a change in the schematic structures of long- Schema-Based Problem Solving term memory and is demonstrated by performance that progresses from slow and difficult (novice-like) to smooth, fast, and effortless automation (expertlike). The change in performance occurs as the learner’s schemas are increasingly associated (activated) with the learning material. Consequently, it requires instructional techniques that take the optimal level of cognitive load into account and do not interfere with schema acquisition (Sweller 1988). In the 1980s, many knowledge-based AI systems used schemas (so-called knowledge packets) as the fundamental basis for computational models of understanding, planning, and problem solving. In this field of application, schemas usually serve as structured beliefs which involve causal-predictive cycles of action and perception. Such models have been used to interpret basic speech acts and linguistic expressions in an agent’s physical environment in terms of grounded schemas (Roy 2005). Another application of schema-based learning is generalization by means of knowledge chunking (DeJong and Mooney 1986). The idea of generalizing with schemas was closely related to the development of explanation-based systems, which are supposed to be capable of learning new schemas which can be used to generalize examples (O’Rorke 1984). This form of generalization is possible because schemas themselves are generalized knowledge chunks. However, up to now, only very few of these artificial systems are capable of generating their own schemas.

MARSHALL Department of Psychology, San Diego State University, San Diego, CA, USA S Synonyms Frame; Plan; Scaffold; Script Definition Schema-based problem solving requires use of specific schemas or templates to recognize, understand, and solve problems. Broadly, such schemas have four characteristics: they are organized so that an individual can quickly identify new instances that are similar to those on which the schema was founded; they are general templates but also have links to specific individual experiences that match the current template; they guide an individual’s efforts to draw inferences, make 2950 S Schema-Based Problem Solving estimates, and create plans to solve problems; and they connect with essential skills or procedures the individual already has. Theoretical Background Problem-solving schemas have most often appeared in arithmetic or algebraic contexts. Hinsley et al. (1977) were among the first researchers to look seriously at the way schemas are used by problem solvers. They focused on the question of whether individuals actually use schema knowledge to solve problems. If so, they reasoned that the following claims must be true: individuals can recognize problem types based on their schema knowledge, individuals can identify problem types without first developing equations to represent the problems, and individuals can use their problem identifications to formulate plans for solving the problems (p. 92). These claims have guided much of the research about how schemas are used in problem solving. Important Scientific Research and Open Questions Research has focused on the underlying relationships within problem-solving schemas and on the types of knowledge that comprise a schema. A problem-solving schema should capture essential information about the situation represented by the problem and provide a scaffold for learning how to recognize it. Thus, a first research question has to do with the nature of problem situations. Riley et al. (1983) focused on the structure of arithmetic story problems such as those found in elementary school classrooms. They discovered that three relationships – Change, Combine, and Compare – capture most of the problems that require addition and subtraction. The importance of their research is that they shifted the focus away from the equations or algorithms needed to solve a problem to the underlying situation represented by the problem. Marshall (1995) later expanded the original three situations to a set of five to cover story problems that appear in pre-algebra classrooms. The research on story problems made it clear that situational information is a key constituent of a problem-solving schema. However, problem solving is more than problem recognition, and a schema is more than a situation description. Active solving is required, and a schema should capture both the situational features and the solution strategies of problem solving. Building on Hinsley et al.’s earlier approach, Marshall (1995) hypothesized that four types of knowledge were essential for schema-based problem solving: identification, elaboration, planning, and execution. To solve problems using a schema, an individual must first recognize the features of the problem that are relevant to the schema (i.e., identification knowledge). Next, the solver needs to figure out how these features relate to past experiences of problem solving (i.e., elaboration knowledge). These two types of information are critical but by themselves insufficient to characterize the schema. The solver must also draw upon two additional types of schema knowledge. Specifically, the solver must formulate plans about how to reach a solution (i.e., planning knowledge) and then must call upon the skills required to carry out the plans (i.e., execution knowledge). A well-formed schema will have these four types of knowledge linked in memory so that retrieval of one component automatically activates the others. Understanding the types of knowledge involved in schema-based problem solving has diagnostic value. Often, the nature of a problem-solving error indicates that the root of the difficulty lies in a faulty schema. An individual can fail to solve a problem for many reasons. The failure may be traced to the attempt to use an incorrect schema. Or, there may be evidence that the appropriate schema was activated but some knowledge component was faulty. In either case, schema-based instruction may remedy the failure.

SEEL Department of Education, University of Freiburg, Freiburg, Germany Synonyms Case-based reasoning; Mental logic Definition Schema-based reasoning is a generalized form of case-based reasoning widely used in cognitive science and artificial intelligence. In both fields of application, the basic assumption is that generalized knowledge is stored in schemas that contain the records of single cases of past successful problem solving. These explicitly represented schemas can be combined with a flexible reasoning mechanism, resulting in an adaptive and context-sensitive approach to real-world problem solving. Schema-based reasoning expands on the idea of case-based reasoning by referring to generalized cases (schemas) rather than specific cases. It thus relies on the effective use of generic contextual knowledge in order to be transferred to a current problem (Turner 1994). Theoretical Background In the 1980s, psychologists and cognitive scientists used previous studies on syllogistic reasoning to develop various theoretical approaches to deductive reasoning. These approaches may be divided roughly into two main classes, the first being syntactic approaches, which assume that people apply syntactic rules which constitute a mental logic when practicing deductive reasoning: “In evaluating a deductive argument, people construct a mental proof or derivation, doing informally what logic students are taught to do formally” (Rips 1984, p. 123). In contrast, semantic or pragmatic approaches are based on the use of so-called judgment schemas. Semantic approaches include different theories, such as the theory of pragmatic reasoning schemas (Cheng and Holyoak 1985), the two-factor theory by Evans (1982), the theory of mental logic by Braine (1990), and the theory of mental models by JohnsonLaird (1983). Cheng and Holyoak (1985) use the concept of pragmatic reasoning schemas, which may be applied to S specific types of situations (e.g., promise, obligation, permission) to explain the influence the content of the premises has on the conclusion. Cheng and Holyoak argue that people possess classes of linguistically based permission schemas that have a fixed internal structure which is determined by pragmatic considerations. The effectiveness of permission schemas (“If you want to do P, then you must do Q”) could be measured in selection tasks, where the success rate has been much superior to what is usually observed in logical tasks. Cheng and Holyoak define permission schemas by a set of production rules that give the same answers to problems of conditional inference as those of formal logic. In sum, pragmatic reasoning schemas provide a convincing explanation of why we generally find it easy to deduce from the pair of propositions – “The father promised the boy five dollars if he would mow the lawn” and “The boy did not receive the five dollars” – that the boy did not mow the lawn. However, this approach is not capable of explaining why it is more difficult to solve problems which have the following logical form: “A rule specifies that a 7 is on the card if an A is on it, and there is no 7 on the card. Is there an A on the card?” The two-factor theory by Evans (1982) is designed to make it understandable why individuals often have a tendency to choose inconsistent answers. When examined more closely, this theory proves to be a conflict model “in which logical and non-logical influences compete for control of the subjects’ responses” (Evans 1982, p. 125). The logical component establishes the extent to which a person’s answers are directed toward the logical structure of the problem. The logical processes a person adopts are conceived of as interpretational processes which may run away and lead to logically incorrect answers. Evans classifies all influences on answers which come about as a result of factors which are logically irrelevant as nonlogical components. Among other things, he emphasizes people’s tendency to accept or choose conclusions which are consistent with their previous knowledge and preconceptions rather than conclusions which may be logically correct but are not consistent with their previous knowledge (belief bias). The theory of mental logic is closely related to Rips’ (1984) system of natural reasoning and includes three main elements: (1) a set of judgment schemas, 2951 S 2952 S Schema-Based Reasoning (2) a program of reasoning which selects the schemas to be used in a line of argumentation, and (3) a set of independently motivated pragmatic principles which influence the interpretation of external attributes and invite one to make nonlogical inferences. A judgment or inferential schema defines a special type of inference by making explicit reference to the conclusion which can be inferred from premises with a certain form. The second component of the theory, the program of reasoning, creates a model of how people select a schema to apply at a certain point in the chain of argumentation. It includes a direct, standard procedure of reasoning and a set of strategies which may be applied if the direct procedure fails. The direct procedure is a simple program. It uses a schema which can be applied to a set of premises (with conditions which prevent continuous loops) and adds the inferences to the set (i.e., it either reuses or evaluates the conclusion). Proponents of this theory claim that this program is available to all humans and that it is used routinely in the processing of texts and language as well as in solving logical problems. The strategic component of the program of reasoning only comes into use if the direct procedure fails, which, however, is often the case in deductive reasoning. According to the theory of mental logic, propositional logic problems can be solved on the basis of the direct reasoning routine. However, deductive inferences may require skills which are beyond the scope of this form of mental logic and are thus relatively difficult. The theoretical approach of mental models has been considered as a promising procedure of reasoning for such cases (cf. Johnson-Laird 1983), but this approach does not belong to the area of schemabased reasoning. Important Scientific Research and Open Questions The various approaches of schema-based reasoning have been contrasted with the theory of mental models (Johnson-Laird 1983) and its application to deductive reasoning for several decades, resulting in an interesting debate. Proponents of schema-based approaches, such as Braine and colleagues, conclude from their studies that the theory of mental logic is superior to the theory of mental models, whereas proponents of the theory of mental models come to the conclusion that their theory is superior to the approach of mental logic. This is not the place to justify the two approaches and the results of studies on them (for an overview, see Braine and O’Brien 1998). However, it is clear that these theories have contrasting strengths and weaknesses. Remaining within the realm of the theory of mental logic, the idea of inferential schemas provides a direct method for making inferences related to real-world problems. A person can perform deductive reasoning either by applying the rules of a system of mental logic or by going through the various means of interpreting the premises of a proposition. Of prime significance in this process is how the premises are represented in the mind. It is on the basis of this mental representation that one can determine how difficult various deductive problems are. Researchers are not yet in agreement as to how much of problem solving is performed through logical-rational processes and to what extent it is influenced by pragmatic aspects which seem irrelevant from the perspective of formal logic and could even lead to systematic, nonlogical distortions. All in all, it must be stated that deductive reasoning has not yet been studied sufficiently from a psychological point of view, seen by the fact that it is still unclear which cognitive processes are involved in deductive thinking. Another area of research on the implementation of schema-based reasoning is the field of artificial intelligence (AI). Actually, the integration of various reasoning modalities into intelligent systems and autonomous agent architectures is one of the most interesting and challenging aspects of current AI. The exploitation of the synergy between different reasoning methods is a major feature of multi-modal reasoning systems, which integrate and combine different reasoning modalities and different knowledge representation formalisms. Case-based reasoning, and in consequence schema-based reasoning, is often considered a fundamental modality in several multi-modal reasoning systems. The basic idea of schema-based reasoning in the area of AI is simple and corresponds to a large extent to the approaches of cognitive science as described above: The relevant knowledge of an agent must be represented explicitly as declarative knowledge structures called schemas, and these schemas can then be activated and used to guide the agent’s problem solving. These contextual schemas represent not only the task-relevant knowledge but also commitments to perform future actions. They therefore allow the agent Schema-Dependent Neocortical Connectivity During Information Processing to go beyond purely reactive decision making and proceed to adaptive and context-sensitive solutions to problems. Contextual schemas represent patterns appearing in the world as well as ones that have been experienced in former problem solving. This means that schema-based reasoning is sensitive to changes in the agent’s environment but enables the agent to automatically adapt to situations. At the moment, the relevant contextual schemas are still given to the agent by other people with experience and expertise. However, in the future it should be possible for the agents themselves to create and modify these schemas based on their own experience and evolving expertise. This is a promising field of current AI research (see, e.g., Portinale et al. 2004).

Schemas have been widely studied in cognitive psychology (Johnson-Laird 1983), but theories as to how this memory enhancement arises are still hard to relate directly to underlying neural processes. Recently, however, neuroscientific studies on schemas, both in rodents and humans, started to shed some light on schema-related mnemonic mechanisms in the brain. S 2954 S Schema-Dependent Neocortical Connectivity During Information Processing Theoretical Background The brain is an interactive and plastic organ. It does not just passively await incoming – bottom-up – information passing through the different senses to be processed to initiate an adequate response. Contrarily, the brain is continuously anticipating and predicting – top-down – how its environment and internal states are possibly going to evolve, so adequate responses are readily available when necessary (Friston 2005). Consequently, the brain is able to function in an optimal manner, spending as little energy as possible on processing the unimportant parts of the continuous stream of incoming information, but readily picking out important features. To continuously influence this information processing, the brain uses internal topdown signals to actively evaluate novel information and mediate how it is best processed and assimilated into its existing schemas. A schema consists of all sorts of representations about the world, interconnected in an intricate network constituted to form a realistic idea of what the world is like. Using these schemas, the brain can predict future events in the world, leading to differential processing of schema-related or unrelated information. When information is consistent with a schema, it will be passed through a fast, efficient processing mode. On the other hand, information that is inconsistent will yield a prediction error (Friston 2005) and will consequently be more elaborately processed in order to fit best preexisting schemas or to build new schemas. Moreover, inconsistent information that is encountered repeatedly might in the end lead to schema adjustment, influencing information processing in the long run. In this view, the strength of the prediction error as a reaction to novel information thus influences how the brain will process this information. By manipulating a prior schema, and testing information processing during the different stages that a new mnemonic trace undergoes, we can gain insights into not only how a schema mediates information processing, but also which different mnemonic mechanisms are affected. Remembering information over time is a complex process consisting of several interrelated subprocesses. Learned information will first reside in short-term working memory, which helps to encode the information into long-term memory. To best merge the new information with the prior information stored in the brain, the information is assimilated and consolidated into the schema over a longer period of time (up to years). Stored information can then be retrieved and might even be reconsolidated after its retrieval. All these mnemonic processes have individual characteristics, but they also show many similarities. For example, encoding of information is found to recruit many of the same brain regions as later retrieval of the same information does. All these mnemonic processes and associated brain activity may be equally or differentially affected by schemas. Research into schemas in the brain can thus help improving our ability to tease these different mnemonic processes apart. During systems consolidation of a memory trace, the hippocampus is found to initially bind different parts of a memory trace, stored throughout the neocortex in a distributed manner. With time, a memory becomes less hippocampally dependent because it is better consolidated into neocortical modules. The hippocampus thus becomes less necessary to retrieve this specific memory over time. Concomitantly, the medial prefrontal cortex (mPFC) increasingly shows more of the characteristics that were initially dedicated to the hippocampus, activating and binding different parts of a memory trace. Consequently, it has been proposed that hippocampal and mPFC influence related to a certain memory trace is balanced, and that this balance shifts from the hippocampus toward the mPFC with time (Takashima et al. 2006). This switch in balance, as a feature of systems consolidation, can presumably be used to probe the effect of a schema on the consolidation process. Important Scientific Research and Open Questions Up to now, only few studies have examined influences of a schema on mnemonic processing in the brain. In rodents, it has been discovered that when a prior associative schema was present in the brain, novel memory traces related to this schema became hippocampally independent faster (Tse et al. 2007). This was tested by overtraining the rodents on a spatial event arena, in which they could find differently flavored food at different locations. Subsequently, the rodents learned novel information that was either related or unrelated to the spatial properties of the event arena. After 48 h, their hippocampus was removed. When testing on memory afterwards, the information that was related to the event area turned out to be remembered, while unrelated Schema-Dependent Neocortical Connectivity During Information Processing information was forgotten. The novel information that was related to the spatial schema was thus faster consolidated and lost its hippocampal dependence already within 48 h, while unrelated information at that point in time was still hippocampally dependent. In humans, the schema-effect on memory has been investigated using functional Magnetic Resonance Imaging (fMRI) both during encoding, post-encoding rest and retrieval of memories that were either related or unrelated to an existing schema. During encoding, and persisting during post-encoding rest, participants with a coherent schema about the storyline of a movie showed a decreased interaction between the hippocampus and the mPFC while watching the last part of this movie and during a rest period thereafter, compared to participants that did not have a coherent schema (van Kesteren et al. 2010a). The participants with the schema thus needed less interaction between these regions compared to the participants without a schema to integrate adequately the novel information, presumably because it was better related to their schema. During retrieval, mPFC activity and connectivity with somatosensory cortex, related to the tactile part of a memory trace, was found to be enhanced for visuo–tactile information congruent with common knowledge versus information incongruent with common knowledge (van Kesteren et al. 2010b). In this experiment, congruency with common knowledge resulted in more mPFC involvement during successful retrieval of the memory trace. These findings credibly fit into the model discussed above, where the balance between the hippocampus and the mPFC shifts with systems consolidation, facilitated by a prior schema. Additionally, these data can account for the view that the influence of a schema on processes related to the assimilation of new information can quite reliably be investigated by looking at this hippocampal-mPFC shift. The question which specific mnemonic processes are affected by prior schema, however, is still partly unanswered. The interaction between the hippocampus and the mPFC has previously merely been attributed to consolidation processes. However, recent insights have revealed that the mPFC is already active during encoding of new information, contradicting this hypothesis. Therefore, we propose that this process, in which the hippocampal function is gradually transferred to the mPFC, is already active during encoding of novel information and is thus already S facilitated by a prior schema in very early stages of information processing. Whether other processes specific to encoding are also facilitated by prior schema, and whether these are crucial for facilitated processing later on, remains to be investigated. The same holds for retrieval and reconsolidation processes. As explained above, these issues can be investigated by looking at connectivity between the hippocampus, the mPFC and other neocortical regions representing parts of the (consolidated) memory trace. Additionally, more research on how a schema influences long-term memory can be beneficial for educational strategies such as developing curricula and detecting why students have trouble comprehending certain issues. Understanding more about how the brain forms schemas and how it processes information either related or unrelated to these schemas will help understanding which learning methods work and why and how they work. By investigating more specific problems that are related to real-life classroom situations, cognitive neuroscience might thus help educational sciences to gain more insight into how students can acquire new knowledge most optimally in classroom settings, from books, and through multisensory and multimedia learning. Therefore, educational sciences and cognitive neuroscience must work closer together in order to best detect and investigate these current issues. In summary, research into the effect of a prior schema on mnemonic processes in the brain is thus far showing promising results. By investigating the hippocampal-mPFC balance, but also by looking at connectivity traces from these brain areas to areas representing specific features of memory traces, it appears that a prior schema facilitates information processing throughout different mnemonic stages, such as encoding, consolidation, and subsequent retrieval. Nevertheless, there are questions that remain open. Next to the possible differentiating effects of mnemonic processes such as encoding, consolidation, and retrieval, schema formation periods can be a unique window when investigating schema formation and its effect on future learning. Furthermore, the question why a prior schema facilitates information processing needs further elaboration by formulating theories and building computational models that mimic this process and are able to predict consequences to be tested in further empirical research, both in animals and in humans. Finally, these fundamental insights into learning and memory 2955 S 2956 S Schema-Like Representations of Categories processes in the brain can be used for better build-up of educational programs and an enhancement of educational strategies (van Kesteren et al. 2010b).

Schemas and Decision Making SANDRA P. MARSHALL1, NORBERT M. SEEL2 1 Department of Psychology, San Diego State University, San Diego, CA, USA 2 Department of Educational Science, University of Freiburg, Freiburg, Germany Synonyms Naturalistic decision making; Schema-based decision making Definition Decision-making schemas coincide widely with problem solving. Both have the same general characteristics and both serve as mental templates against which a decision maker or problem solver maps a specific situation. Both also draw heavily on prior experiences, using them to shape the current interpretation of the decision or problem. However, schema-based decision making is distinct from schema-based problem solving. The key issue in problem solving is recognizing the underlying nature of the problem so that a known solution strategy may be applied if one exists, whereas, in decision making, the problem is usually known, but the solution strategy is not. The key issue here is how to select one strategy from many available alternative strategies. From a schema perspective, both decision making and problem solving utilize the same types of long-term knowledge and cognitive processes, but the relative importance of the basic schema knowledge components varies. Theoretical Background Schema-Like Representations of Categories ▶ Schematic Influences on Category Learning and Recognition Memory Research about schemas and decision making has been predominantly focused on military settings. It has been closely related to the study of situation awareness and its importance in tactical decision making (Endsley 2000). Situation awareness refers to how well an individual perceives and comprehends the elements in Schemas and Decision Making a given environment which is constantly changing so that a decision maker must constantly adapt and adjust the view of the situation to accommodate these changes (Endsley 1995). Actually, military operators and decision makers require situation awareness to understand the goals and decision tasks for a specific set of circumstances (Craig 2001; Klein et al. 1986). Individuals with good situation awareness are believed to make better and more efficient decisions. Thus, situation awareness is analogous to problem recognition in schema terms and is an essential part of a decision-making schema. It spans two schema knowledge components: identification knowledge and elaboration knowledge (see the entry on schema-based problem solving). Schema research grew out of the need to better understand situation awareness, mental models, and critical thinking in relation to individuals working in stressful situations. In particular, research about schemas in decision making has focused on the identification and elaboration components of schema knowledge in tactical settings, attempting to further understand how these two types of knowledge intersect. Based on this research, the Recognition Primed Decision (RPD) model has been developed in the field of natural decision making (Klein 1989). The starting point of this model is an action of the decision maker that is based on both the perception of a known or prototypical situation and a serial strategy of the evaluation of behavioral options. That is, a person conceives a situation in terms of familiarity with past experiences. The rating of familiarity in relation to a set of known cases provided the person with the identification of achievable goals, relevant details, expectations, and plausible actions of decision making. Based on an activated schema the decision maker can refer to experiences in order to generate a possible option of action. The rating of this option occurs by means of a mental simulation (thought experiment) with the aim to check if there are some risks for realizing the option. The RPD model of schemabased decision making can be summarized as depicted in Fig. 1. The RPD model contains aspects of problem solving and judgment formation in accordance with processes of natural decision making. Moreover, in its emphasis on mental simulations of behavioral options, it also corresponds with the theory of mental models (Kuipers 1994). Additionally, the RPD model includes S 2957 the concept of situation awareness as it plays an important role in the fields of military or pilot training since the 1980s. Important Scientific Research and Open Questions Research on schemas and decision making is relatively sparse because this is a relatively new field of interest. It is an area of some importance in applied areas such as military decision making because these decisions are made in real-world settings and have significant consequences. Two ongoing areas of research are the differences between different types of settings (such as operational versus tactical) and the relative importance of the four knowledge components (i.e., identification, elaboration, planning, and execution). Schema-based decision making is closely related with the field of naturalistic decision making which investigates how people make decisions under risk in everyday situations. Decision making under risk is in general characterized by dynamically changing conditions, the challenge to respond immediately to these changes, ill-defined tasks, time pressure, and farreaching personal consequences in case of mistakes. Since the 1980s, researchers from different fields have developed theoretical models to explain how experienced and inexperienced decision makers make decisions under risk. Some of these models are related to the expected utility theory (EUT) which aims at weighting evidence and choosing an optimal action. Kahneman and Tversky (1979) have developed the prospect theory as a variant of EUT by arguing that a decision maker weights achievable results with higher scores than results which are only probable. Furthermore, decision makers show a tendency of preferring strongly weighted low probabilities as well as they are more sensitive with regard to uncertainty than to risk. Although the relevance of the prospect theory for decision making in general is widely accepted in the literature, its applicability for decision making under risk has been questioned because it does not take into account important factors involved in natural decision in complex situations. Klein and Calderwood (1991) argue that analytical methods of decision making under risk eventually fail because they need too much time and lack the flexibility to respond to rapidly changing conditions of situations. In accordance with the idea of schema-based decision making, it can be S 2958 S Schemas and Decision Making Experience the Situation in a Changing Context Reassess Situation No Is the situation familiar? Seek More Information Yes (Recognition of match to prototype) Activation of information from memory Yes Are expectancies violated? Plausible Goals Relevant Cues Expectancies Actions 1...n No Mental Simulation of Action (n) Yes, but Modify Will it work? No Yes Implement Schemas and Decision Making. Fig. 1 The complex RPD strategy (Adopted from Klein and Calderwood 1991) argued that the activation of a specific schema brings about enormous time advantages in mastering challenging situations if they are similar and belong to the same category (Falzer 2004; Marshall 1995). However, in the case of novel phenomena and problems, the available schemas are eventually inappropriate and must be replaced by mental models. Indeed, the theoretical approach of mental models emphasizes cognitive processes of generating plausibility and of probabilistic reasoning (Gigerenzer et al. 1991) that are involved in decision making under risk. Therefore, natural decision making on the basis of mental models can be considered as a theoretically sound alternative to schema-based decision making.

Schemas in the Brain ▶ Schema-Dependent Neocortical Connectivity During Information Processing Schematherapy ▶ Schema Therapy S 2959 Definition The title, schematic influences on category learning and recognition memory, means that our mental representations of categories, such as dogs and friends, are schema-like. A ▶ schema is a knowledge structure that provides a set of expectations based on past experience. For example, a person may have a schema for libraries. When this schema is activated, it makes properties like books and desks available. ▶ Category learning is the process of forming representations of categories. ▶ Classification learning is one type of category learning, in which the learner acquires information about categories through classifying examples. For example, a child may classify an animal as a bird using its properties, such as small and flying. The child may learn that the animal is indeed a bird, strengthening the hypothesis about which properties predict the bird category. Alternatively, the child may learn that the animal is a mammal, leading to a modification of the hypothesis. One way to study how learners represent categories is by measuring their recognition memory for information about the categories and their members. Interestingly, recognition results in category learning studies parallel those in schema studies, suggesting that people develop schema-like representations of categories. Theoretical Background Schematic Bases of Category Learning ▶ Schematic Influences on Category Learning and Recognition Memory Schematic Influences on Category Learning and Recognition Memory YASUAKI SAKAMOTO Howe School of Technology Management, Stevens Institute of Technology, Hoboken, NJ, USA Synonyms Schema-like representations of categories; Schematic bases of category learning People use categories to generalize from past experience to the current situation that they may not have encountered previously. For example, once people categorize a never-before-seen animal as a dog, they can infer that the animal may bark and bite. This ability to use categories is critical because it allows people to process information efficiently and prepare their actions in time. Categories guide the encoding of new information and retrieval of stored information that is relevant to the present task. Schemas serve similar functions. For example, a library schema, when activated, provides people with a certain set of expectations such as being quiet and borrowing books. Like categories, schemas guide the encoding and retrieval of information, and inform people how to act. The two literatures address a related set of issues. In particular, both literatures are concerned with how people process information in relation to existing knowledge structures, such as categories and schemas. Category learning researchers are also interested in how S 2960 S Schematic Influences on Category Learning and Recognition Memory people acquire and represent categories. Consequently, measures of recognition memory for studied information figure prominently in both category learning research and schema research. Sakamoto and Love (2004) drew parallels between these two literatures and imported ideas from work in schemas to the category learning literature. Memory for schema-consistent and schema-inconsistent information is well studied in schema research. For example, whereas seeing desks in a library is schema-consistent, seeing beds is schema-inconsistent. A meta-analysis by Rojahn and Pettigrew (1992) revealed that when measures of recognition memory were corrected for false alarm rate, there was a recognition advantage for schema-inconsistent information over schemaconsistent information. For a library schema, a common false alarm might be reporting to have seen a desk when in fact a desk did not appear in any studied scene. In category learning research, Palmeri and Nosofsky (1995) found a recognition advantage for inconsistent information over consistent information. In their studies, subjects learned to classify 16 geometric stimuli, one by one, into one of two mutually exclusive categories through numerous trials with corrective feedback. Most stimuli could be classified by a simple rule: For example, the rule might be “the large items are in category A, and the small items are in category B.” These rule-following stimuli are analogous to schema-consistent information. However, two stimuli were inconsistent with the rule: There was a large item belonging to category B, and a small item belonging to category A. These rule-violating items are analogous to schema-inconsistent information. Following learning, subjects completed a recognition memory test consisting of studied items and foil items. The main finding was that the subjects recognized the two rule-violating items better than the rule-following items; they selectively attended to the rule during learning, and the two rule-violating items stood out. Like in the schema research, there is a recognition advantage for items that deviate from a salient regularity in the category learning research. The schema literature further suggests that the strength of the regularity, measured by the proportion of items that conform to the regularity, modulates the advantage for deviant items. For example, Rojahn and Pettigrew (1992) found in their meta-analysis that the memory advantage for the schema-inconsistent items became greater as the proportion of the schemainconsistent items became smaller. Similarly, Sakamoto and Love (2004) found in a category learning experiment that the memory advantage for the rule-violating item was greater when the violated rule was stronger. In Sakamoto and Love, as in Palmeri and Nosofsky (1995), most members of categories A and B followed an imperfect rule. The strength of the rule was manipulated by varying the frequency of rule-following items: Whereas category A contained eight rule-following items, category B contained four. Each category contained a ruleviolating item. To master the classification task, subjects needed to differentiate category B’s rule-violating item from the eight rule-following items in category A, and category A’s rule-violating item from the four rulefollowing items in category B. After learning, these rule-violating items were remembered better than the rule-following items, replicating Palmeri and Nosofsky. Furthermore, as in the schema research, memory for the category B’s rule-violating item, which violated the more frequent rule of category A, was enhanced relative to that for the category A’s rule-violating item. The parallel results from the schema and category learning research indicate that the learners develop schema-like representations of categories, and challenge many existing models of category learning. For example, exemplar models (e.g., Kruschke 1992), which have enjoyed a long history of explaining key psychological phenomena in the category learning research, cannot account for the enhanced recognition of rule-violating items without modifications. Exemplar models store every studied item in memory as a separate trace. An item is classified into category A or B depending on the item’s relative similarity to all stored exemplars belonging to categories A and B. The likelihood of recognizing an item as a studied item is proportional to the sum of the item’s similarity to all stored exemplars. The exemplar models predict no recognition advantage for rule-violating items because these items share the same similarity relations with stored exemplars as rule-following items do. The exemplar models’ recognition memory is not sensitive to the deviant nature of rule-violating items. Rule-based (hypothesis-testing) models of category learning cannot account for the entire pattern of the results either. A rule-plus-exception model Schematic Influences on Category Learning and Recognition Memory (Nosofsky et al. 1994) constructs rules and stores exceptions to the rules. Rules represent the rulefollowing items. Information about inconsistent items is explicitly stored as exceptions. Classification decisions are based on first matching the item to stored exceptions. If there is no match, then the model applies the rule. The likelihood of recognizing a test item is determined by summing the output from the rule and the output from the exceptions. The separate storage of inconsistent information allows the ruleplus-exception model to predict a memory advantage for rule-violating items. However, this model underpredicts the recognition memory for studied rulefollowing items because rules encode very little information about these items. Furthermore, rulebased models cannot account for the greater recognition advantage for rule-inconsistent items violating a stronger rule without also incorrectly predicting the enhanced recognition of rule-following items that conform to the stronger rule. The failures of the rule-based models and exemplar models suggest that humans store more than just rules to represent rule-following items, and they do not store every individual item as a separate memory trace. Instead, they build schema-like representations, in which rule-following items are encoded as a set of expectations, and rule-violating items are stored separately. One candidate is cluster-based representations. The clustering model (Love et al. 2004) can predict the memory advantage of rule-violating items. It represents categories by one or more clusters. The first stimulus item encountered becomes the initial cluster. The clustering model tries to group the next item into this cluster. If this attempt leads to a classification error, the model recruits a new cluster for the error-producing item. The model tries to assign subsequent items into the clusters that are most similar to the items. In this way, the clustering model joins similar items together and encodes rule-violating items separately when they elicit classification errors. An item is classified according to the category label associated with the cluster it is assigned to. Recognition response is determined by summing the output of all clusters. In the clustering model, whereas the rule-following items will tend to cluster with one another, each ruleviolating item will be isolated in its own cluster. Because of this differential storage, rule-violating items will be more distinctive in memory and result S 2961 in a recognition advantage. Furthermore, unlike the rule-plus-exception model, the clustering model can correctly predict some recognition memory for studied rule-following items because rule-consistent clusters encode more information than just the rule. The clustering model can also predict enhanced memory for the item that violates the stronger (i.e., more frequent) regularity by recruiting more clusters to represent the stronger regularity. The rule-inconsistent cluster representing the item that violates the stronger regularity is likely similar to a number of rule-consistent clusters. To differentiate itself, more specific information needs to be encoded for the rule-inconsistent cluster, which gives a recognition advantage for the rule-inconsistent item. Important Scientific Research and Open Questions Schema research examines pre-established knowledge structures, and thus it is difficult to monitor the development of schemas or study how they are acquired. In contrast, in category learning research, subjects acquire novel categories during an experimental session, and researchers can develop models of how representations of categories are formed. These models make precise predictions and may prove to be valuable tools for research in schemas. At the same time, applying category learning models to schema research will require extending these models to incorporate factors such as prior knowledge and one trial learning that are important in everyday learning but are often ignored in category learning research. To build such models, a stronger link between schema research and category learning research is needed. More work should examine memory for consistent and inconsistent information in category learning research. There are many ways people learn about categories other than classification learning. For example, in inference learning, the learner acquires category knowledge by inferring properties of category members. A child inferring characteristics of birds, and a medical student inferring symptoms of patients with a certain disease are two examples of inference. Based on the corrective feedback, they learn the category-property associations. Inference learning is essentially the opposite of classification learning. Whereas the inference learner predicts the properties associated with the given category, the classification learner S 2962 S Schematization predicts the category label for an item with the given properties. It is unclear how people would process consistent and inconsistent information in inference learning, and whether existing models of category learning could capture aspects of inference learning behavior. This line of work will give researchers the opportunities to extend and refine current theories of category learning.

Schematization ▶ Exemplar Learning and Schematization in Language Development School Atmosphere ▶ School Climate and Learning School Choice ▶ Homeschooling and Teaching School Climate and Learning ERIN MORAN1, JOHN S. CARLSON1, BETTY TABLEMAN2 1 College of Education Erickson Hall, Michigan State University, East Lansing, MI, USA 2 School of Social Work Baker Hall, Michigan State University, East Lansing, MI, USA Synonyms Academic outcomes; School atmosphere; School culture; School environment Definition School climate refers to characteristics of the school building or classroom setting. School climate is often closely associated with school culture (i.e., the values, attitudes, and expectations that are characteristic of a particular school district). Factors associated with a school’s climate can have an impact on student learning. A positive school climate fosters learning and student success through a caring, safe, and supportive environment. A negative school climate can inhibit School Climate and Learning student achievement. The nature of a particular school’s climate may be evident through a close examination of physical, social, affective, and academic conditions. Theoretical Background Bronfenbrenner’s Bioecological Perspective evaluates the interaction between person and environmental factors by providing a model depicting the various systems which influence an individual’s development and learning. Such system levels include the individual’s immediate environments including family, social groups, and school, the interaction of these environments, external environments such as the parent’s workplace, and larger cultural contexts, all combining to affect development. The school is an important factor within this bioecological system, because a child spends a large portion of his/her day within this context and is greatly influenced by the culture of this institution and the social interactions created within it. Abraham Maslow proposed a Hierarchy of Needs to understanding the essential needs of individuals in order to achieve higher self-actualization and learning. This theory is represented as a pyramid, with the most basic needs at the bottom, representing the importance of fulfilling these basic needs in order to achieve higher actualization. While physiological needs (e.g., breathing, food, water, and sleep) are the most basic, more complex needs that must be met include safety and social needs. If an individual does not feel safe, have a sense of belonging within a school setting, and have a healthy sense of themself, then learning and growth cannot occur because these essential needs are not being met. When left unsatisfied, the need for safety and belongingness will preempt focus and motivation over school achievement. Thus, in order for students to be able to learn at their greatest potential, schools must be able to create a school climate which fosters a feeling of safety and belonging through cultivating positive relationships and support. B.F. Skinner, in his behaviorist model of learning, examined the critical role that environmental rewards and punishments play in influencing behavior and learning through his operant conditioning model, in which behavior is reinforced with rewards or punishments in order to affect the future likelihood of the behavior. With this work, Skinner showed that the S likelihood that a behavior would be repeated increased when a reward was provided for this behavior and that the likelihood would decrease if a punishment followed the behavior. This model creates an important building block in understanding how the individual’s environment affects individual behavior and learning. Similar to learning theory, social learning theory emphasizes the importance of the interaction between social environmental influences and the individual’s internal processes in learning and behavior. Social learning theory proposes that individuals learn through reinforcement, punishment, and observational learning. Reinforcement and punishment can easily be enforced through student–student interactions or through teacher–student interactions within the school setting. Observational learning suggests that much of what an individual learns is through the observation and imitation of others with whom they are in close contact or whom they view as role models. Within school settings, most learning of expectations and appropriate behavior occurs through watching peers or role models, such as teachers or older students. A social and emotional learning (SEL) education framework promotes teaching a core set of social and emotional skills to help children build resilience and handle challenging situations. The SEL program teaches students the knowledge, skills, and attitudes they need to create positive relationships, make appropriate decisions, and care for others (Collaborative for Academic, Social, and Emotional Learning 2009). SEL focuses on five categories of skills: self-awareness, selfmanagement, social awareness, relationship skills, and responsible decision-making skills. This type of framework works to include students, create an atmosphere of warmth and respect, as well as build positive relationships and skills for student–student and teacher– student interactions. The inclusion of such a program and its goals within schools have allowed students to develop better skills in social interaction and therefore improve the social atmosphere of the school climate. Each of these theories and research supports the importance of identifying and creating positive school climates in affecting learning. In order to understand the learning process, one must look not only at the individual but also at the environmental influences on learning. A positive, caring, safe, and suppportive school climate provides a nurturing place for students to learn and can increase their chances for success. 2963 S 2964 S School Climate and Learning Important Scientific Research and Open Questions There is currently an increased focus on school performance and schools are being held responsible for improving academic performance. However, it is important for schools to not only make changes to curriculum and classroom instruction, but to take note of the school climate and school culture, which can have important effects on learning (Tableman 2004). School climate refers to the characteristics and organization of the school building and classroom, whereas the term school culture refers to the districtwide values and attitudes that provide a set of standard expectations. While a positive school climate can be created within a building or classroom, the school culture of the district can play an important role in positively or negatively influencing the school climate. Often positive changes to the school climate cannot be achieved without similar and supportive changes to the school culture of the district. Tableman (2004) presents the symbols, values, and assumptions/beliefs that constitute a school culture that supports learning and one that impedes learning. A school culture supporting learning will arrange the building in a way that best serves the needs of children, values the opinions and participation of administrators, parents, teachers, and students, and is a place where all students are able to learn and where parents play an active role in education and want their children to succeed. On the other hand, a school culture that impedes learning will not emphasize child accomplishments, the decision process will not include parents, teachers, and students, and the school will make the assumptions that parents do not care about their child’s education and that some students are incapable of learning. While school climate has been discussed in efforts to reform school systems or improve academic performance, it can also serve as a resolution to such issues as bullying, student conflicts, and character building. Tableman (2004) identified four aspects of a school climate that can have positive or negative effects on the school and learning: a physical environment that is welcoming and conducive to learning, a social environment that promotes communication and interaction, an affective environment that promotes a sense of belonging and self-esteem, and an academic environment that promotes learning and self-fulfillment. For example, a physical environment that supports learning might include a limited number of students, open and welcoming classrooms, and a building in which students feel safe and comfortable, whereas a physical environment that hinders learning might include a large number of students, classrooms that are not visible and welcoming, and a building in which students may worry about being bullied in the classrooms or hallways. Much research has been conducted that highlights the value of promoting a positive school climate, including higher grades and achievement, better socioeconomic health, higher attendance, fewer suspensions, lower dropout rates, higher self-esteem, less anxiety and substance abuse, and higher standardized test scores (Scales and Leffert 1999). Research has also been conducted specifically looking at the size of the school as an important indicator of school climate. The number of students in a school can affect the physical and social environment of the school, and it has been found in research that smaller schools allow for better student–teacher interactions and more involvement from students (Cotton 1996). Smaller schools, generally defined as falling within the range of 300–400 students in elementary settings and 400–800 students in secondary settings, allow for more involvement in extracurricular activities, better attitudes about school from students and teachers, fewer behavior problems, and a higher sense of belongingness among students. The concept of school climate has gained importance within research on school effectiveness and learning over the past two decades. A safe school environment that fosters relationships where students feel respected, engaged with their work, and competent is essential to the learning process (National School Climate Center 2009). However, a gap exists between the research on the importance of creating positive school climates and the implementation of this knowledge into school practice. In order to effectively improve or change a school climate, the school climate must first be identified. There are several measures available at the elementary school, middle school, and high school level to determine school climate outcomes. Some elementary school measures with high reliability, validity, and scoring methods include the School as Caring Community Profile – II, the Sense of School as Community Scale, and the Liking for School Scale. At the middle school level, some measures receiving high ratings in these areas include the School Climate and Learning Kettering Scale of School Climate and the School Climate Questionnaire. At the high school level, a highly rated measure includes the School Culture Scale (Adapted from the Character Education Partnership, as cited in Tableman 2004). School Climate can also be assessed by measuring the physical, social, affective, and academic environmental factors as identified by Tableman (2004), which can be modified into a survey checklist. Once the school climate and areas of weakness have been identified, then change is possible. Change to the school climate will take time and will involve many players within the school system. While positive changes to a school climate may temporarily change the attitudes and behaviors of students and teachers, these changes will not be effective or lasting without the support and change to the district-wide school culture (Tableman 2004). School culture and climate change begins with the district superintendent who will make decisions about the district’s mission, goals, and staff, whereas on a school level, the principal is responsible for promoting change, setting expectations, and getting teachers involved in the decision-making process. In promoting change, a school system can promote a safe and orderly environment (i.e., keep buildings in good physical condition, implement consequences for inappropriate behaviors, create anti-bullying and conflict resolution workshops, or create time-out areas for students to use throughout the day), facilitate conditions that promote relationships and interaction (i.e., build smaller schools, use smaller teacher–student ratios, and promote small group activities), and promote a positive affective environment (i.e., have students attend summer school rather than retention, create a cooperative environment rather than a competitive one, and ensure that students have a positive relationship with at least one adult figure in the school) (Tableman 2004). An interaction of some or all of these suggestions to change can work to create a more positive school climate and culture. It is important to note that although teachers can establish a positive school climate within their classroom (or principals within their building), unless they are supported by the district through a supportive school culture, they often burn out and leave. In 2007, the Office of Superintendent of Public Instruction in the state of Washington constructed an education manual highlighting nine research-based characteristics of S 2965 high-performing schools (Shannon and Bylsma 2007). These nine characteristics incorporate actions at the federal, state, district, building, and classroom levels. Among the nine characteristics are the following elements of a positive school climate and school culture: a clear and shared focus, high standards and expectations for all students, effective school leadership, high levels of collaboration and communication, a supportive learning environment that is safe, healthy, engaging, and intellectually stimulating, and high levels of family and community involvement. Although significant research has been done in the field of school climate and culture, and their effects on learning, there still are many areas that need to be further addressed. While school culture and school climate have been discussed, there still remains the issue of what the impact of school culture at a district level is on school climate within individual schools, which is the responsibility of principals and teachers. This area is important to investigate because it will help to shed light on how changes in the school culture can lead to changes in the school climate in order to improve student learning. Further investigation into effective methods of incorporating learning and training in developing a positive school climate and culture into academic and in-service preparation for teachers, principals, and superintendents would benefit schools in putting theory into practice.

MCINERNEY Educational Psychology Psychological Studies Department, Block D1, 2Fl, Room 15, The Hong Kong Institute of Education, Tai Po, Hong Kong Synonyms Achievement motivation; Engaged learning Definition Motivation (derived from the Latin motives, a moving cause) may be defined as an internal state that instigates, directs, and maintains behavior. School motivation may be defined by four qualities: CHOICE, motivated students choose to do some activities rather than others. ENERGY, motivated students invest high energy, characterized by involvement, enthusiasm, and interest in activities. STANDARDS, motivated students seek high personal standards in activities. CONTINUING MOTIVATION, motivated students return to activities voluntarily, time and again, because they enjoy and feel rewarded through them. Theoretical Background Historically, the dominant paradigm of school motivation until the early 1980s was reinforcement theory. B. F. Skinner (1954) has had a powerful impact on the world of education. Skinner’s work is now commonly considered an extension of Thorndike’s ▶ law of effect. In general, Skinner believed that all animals, including humans, learn things by having certain aspects of their behavior reinforced while other aspects are not. ▶ Positive reinforcement occurs when something, such as a reward, is added to the situation that makes the performance of a particular behavior more likely in the future. ▶ Negative reinforcement occurs when something unpleasant is removed from the situation contingent upon the performance of the behavior. Under this paradigm, reinforcement acts as the motivating force behind continued involvement in an activity. For children, reinforcement may be: material, such as toys or some enjoyable activity; token, such as stamps and gold stars; or social, such as the goodwill and recognition of the teacher or competition. Often this style of reinforcement is called extrinsic reinforcement as it is externally applied, usually by a teacher. Positive reinforcement is considered more effective than negative reinforcement. While reinforcement is pervasive in classrooms as a motivational tool, the current predominant theoretical paradigm of school motivation is cognitive. Cognitive theories emphasize mental processes and perception as important elements of motivation and the personal construction of the meaning of experiences which impacts on an individual’s level of motivation. Implied in such views of motivation are a concern with personal beliefs and values, perceptions School Motivation of self, including perceptions about self-worth, abilities and competencies, and goals and expectations for success or failure. This shift from elementary and basic theories of motivation based on behavioral models to cognitive models has had a strong impact on the way in which we look at classrooms and schools and how educators may most effectively engage students in learning. Among cognitive theories are ▶ attribution theory, ▶ expectancy-value theory, goal theory, ▶ selfdetermination theory, personal investment theory, self-worth theory, and self-related constructs such as ▶ self-concept, self-regulation, and ▶ self-efficacy theories. Each of these theories implicitly or explicitly addresses choice, energy, standards, and continuing motivation. Expectancy-value theory. This theory proposes that in order to be motivated, students need to have a strong expectation that they will be successful in a learning activity. If they believe success is beyond their capacity, they will be less motivated. However, even if students possess a strong expectation of success but do not value an activity/outcome, they will not be motivated (Wigfield and Eccles 2000). Hence, the essence of the motivational state that drives engagement is believed to be a judicious blend of expectation of success and valuing success. Expectancy and value are considered to be influenced by task-specific beliefs such as ability beliefs (i.e., the individuals’ perceptions of their current competence for a given activity), perceived difficulty of the task, and the individual’s goals for schooling, sense of self, and affective memories for similar tasks. These social cognitive variables are influenced by an individual’s perceptions of their previous experiences and a variety of wider socialization influences. The theory holds that students’ expectancy and task values directly predict their achievement outcomes, including performance, persistence, and choices of which activities to do. Empirical support for these proposed linkages has been found in longitudinal studies of children ranging in age from 6 to 18 years. Even when level of previous performance is controlled, students’ competence beliefs strongly predict their performance in different domains, including math, reading, and sports. It appears, however, that while valuing a task may be important in the initial choice of activity, expectancy of success is more important to motivation and performance than valuing after that. S 2967 Attribution Theory When students have successes or failures, they automatically search for reasons. The motivational importance of such perceived causal control over one’s successes and failures has been a focus of Bernard Weiner’s attribution theory (Weiner 2004). The theory rests on three basic assumptions. First, it assumes that people attempt to determine the causes of their own behavior and that of others. Second, it assumes that the reasons people give to explain their behavior govern their future behavior in predictable ways from one situation to the next. And third, it assumes that the specific causes attributed to a particular behavior will influence subsequent emotional and cognitive behavior in predictable ways. Hence, the essence of the motivational state that drives continuing engagement or disengagement in an activity is believed to be an individual’s explanation and interpretation of the causes of their successes and failures. In other words, individuals ask questions such as, “Why did I fail the exam?” or “Why did I achieve so well?” It is, however, more likely that these types of questions are asked after failure, rather than after success experiences. Weiner originally postulated four causes that are perceived as most responsible for success and failure in achievement-related contexts: Ability, Effort, Task Difficulty, and Luck. Ability refers to a person’s perceived performance capacity on a particular task. Effort refers to the energy expended on the task. Task difficulty refers to the perceived difficulty of the task, i.e., tasks that most people can perform are considered easy, while tasks that few can master are considered difficult. Last, luck refers to the variables that lie outside personal control that may affect the performance on the task (other than the first three mentioned), e.g., such as being unwell. Dimensions of internality and externality, and controllability are believed to influence the motivational impact of attributions. Ability and effort are considered internal dimensions, task difficulty and luck are considered external dimensions. Ability, task difficulty, and luck are considered uncontrollable, effort is considered controllable. According to the theory attributions to the internal controllable dimension, effort is more efficacious than attributions to either internal or external uncontrollable dimensions (ability, luck, task difficulty). S 2968 S School Motivation Achievement Goal Theory ▶ Achievement goal theory posits that there is an integrated pattern of beliefs (goal orientations) that lead students to approach, engage, and respond to achievement tasks and situations in specific ways (Schunk et al. 2008). Goals represent the purposes that students have in different achievement situations and are presumed to guide students’ behavior, cognition, and affect as they become involved in academic work (Ames 1992). Hence, the essence of the motivational state that drives engagement in an activity is believed to be an individual’s self-thoughts about the purpose(s) of achieving (or being successful) in the activity. Two academic goals have been the focus of much theorizing: mastery goals (sometimes called learning goals or task goals) and performance goals (sometimes called ego goals or relative ability goals). Central to a ▶ mastery goal is the belief that effort leads to success: the focus of attention is the intrinsic value of learning. With a mastery goal, individuals are oriented toward developing new skills, trying to understand their work, improving their level of competence, or achieving a sense of mastery. In other words, students feel successful if they believe they have personally improved or have come to understand something. Their performance relative to others is irrelevant; of greater importance to them is completing the task. The latest development of achievement goal theory has bifurcated mastery goal orientation into two forms, mastery-approach and mastery-avoidance (Elliot and McGregor 2001). While a mastery-approach goal orientation is essentially identical to the mastery goal orientation explained above, a mastery-avoidance goal focuses on avoiding showing misunderstanding, or avoiding not learning or not mastering the task. Central to a performance goal is a focus on one’s ability and sense of self-worth. Ability is shown by doing better than others, by surpassing norms, or by achieving success with little effort. Public recognition for doing better than others is an important element of a performance-goal orientation. Performance goals and achievement are “referenced” against the performance of others or against external standards such as marks and grades. Consequently, “self-worth” is determined by one’s perception of ability to perform relative to others. Hence, when students try hard without being completely successful (in terms of the established norms), their sense of self-worth may be threatened. Performance goals have also been bifurcated into performance-approach and performance-avoidance goals. Students who hold a ▶ performance-approach goal orientation want to do better than their classmates so that they will be recognized as competent by their peers, teachers, and parents. Students who hold a ▶ performance-avoidance goal orientation do their academic work primarily because they fear appearing incompetent (Elliot and McGregor 2001). Adaptive and maladaptive achievement goals. Research suggests that mastery-approach is an adaptive motivator. Students adopting a mastery-approach goal orientation tend to use high levels of deep cognitive strategies, such as elaboration, as well as metacognitive and self-regulatory strategies. A similar pattern of findings has been found across cultures. The few studies that have examined a mastery-avoidance goal orientation have demonstrated that this orientation is mostly unrelated to cognitive strategies but negatively related to intrinsic motivation, perceived competence and classroom grades, and positively related to negative emotions such as test anxiety and worry, help-seeking threat, and to less adaptive approaches to learning. Research has also demonstrated the adaptive effects of a performance-approach goal orientation on valued educational outcomes such as deep cognitive strategies, positive affects, positive peer relationships, and classroom grades. It should also be noted, however, that a performance-approach goal orientation has also been associated with negative outcomes such as anxiety, disruptive behavior, and low retention of knowledge. In contrast, students who adopt a performanceavoidance goal orientation are more likely to use surface cognitive strategies such as rote memorization and rehearsal. Furthermore, a performance-avoidance goal orientation also appears to diminish intrinsic motivation for learning and is related to low levels of task engagement and persistence, avoidance of help seeking, anxiety, procrastination, and low grades. A third type of goal orientation, work avoidance, has received less attention by researchers but appears to be quite important in influencing students’ attitudes toward their school work (Dowson and McInerney 2001). ▶ Work-avoidance (or work-avoidant) goals represent a type of goal orientation, where students deliberately avoid engaging in academic tasks and/or attempt to minimize the effort required to complete School Motivation academic tasks. This orientation, although distinct from both performance and mastery orientation, may nevertheless combine with these orientations to affect students’ cognitive engagement and academic achievement. Effective Goal Setting The above section describes specific types of goals referred to as achievement goals, i.e., the psychological purposes a student has for engaging in a task. However, the term “goal” is also used in an alternative manner to refer to the nature (quantity or quality) of an outcome (performance) that individuals are trying to accomplish (Locke and Latham 2002). From this perspective, the essence of the motivational state that drives continuing engagement in an activity is believed to be the specificity, appropriateness, and achievability of desired goals. Effective goal setting is considered essential to effective motivation and involves establishing quantitative and qualitative standards or objectives to serve as the aim of one’s actions. Setting appropriately challenging levels of goals, divided according to different phases of attainment, is considered crucial to motivating students to engage in self-regulated learning (Schunk 1990). Goals help give structure to student learning, and a set of benchmarks by which students and teachers can evaluate progress. Knowledge that progress is being made toward desired goals is considered motivational, enhances students’ self-efficacy, and leads students to select new, challenging goals. There are three important aspects of goal setting. First, goal setting is believed to be more effective when goals are proximal (short-term) rather than distal (long-term). This is because students are less likely to become discouraged or unmotivated during long-term tasks when they set short-term goals (Locke and Latham 2002). Although the distal goal is important for students to keep in mind, progress toward a longterm goal is sometimes difficult for students to gauge. Short-term goals can raise self-efficacy simply by making a task appear more manageable, and they can also enhance perceptions of competence by giving continual feedback that conveys a sense of mastery. Second, it is believed that goals that incorporate specific performance standards are more likely to enhance motivation and ▶ self-regulation than broad goals such as “you must do your best” or “you should try hard.” Specific goals raise performance because they specify the S 2969 amount of effort required for success and boost selfefficacy by providing a clear standard against which to determine progress. Third, it is believed that goals should be moderately difficult or challenging. Unlike the first two points above, goal difficulty does not follow a linear relationships to performance. Overly easy goals do not motivate, neither do goals perceived to be impossible to achieve. Self-Efficacy Students’ self-efficacy refers to their perceptions or beliefs of capability to learn and perform particular academic tasks at particular levels at a particular point in time. Efficacy beliefs influence how people feel, think, motivate themselves, behave, and overall achievement (Bandura 1997). For example, if students enter an achievement situation with high self-efficacy perceptions, they believe that they can accomplish what the achievement situation requires them to do; as a consequence, they are likely to approach tasks with confidence and engage in them willingly, actively, and persistently. On the contrary, students who are low on self-efficacy beliefs are unsure what they can achieve or even convinced that they cannot do the task; as a result, they doubt their own capabilities for success and, hence, are more likely to try to avoid the situation, or if this is not possible, to give up easily when they encounter frustration and failure. From this perspective, the essence of the motivational state that drives engagement in an activity is believed to be the level of self-efficacy the student has for the task at hand. Research has operationally defined and assessed self-efficacy with reference to the capabilities needed to succeed in particular achievement situations. In this regard, the term has a more specific meaning than such terms as academic confidence or academic self-concept. In general, this research has documented the positive role of self-efficacy beliefs on students’ effort, persistence, and choice of activities, academic performance, interest, management of academic stressors, and growth of cognitive competencies. Self-Regulation Drawn from self-efficacy theorizing, self-regulation is considered to be a process that involves self-generated thoughts, feelings, and actions for attaining academic goals (Zimmerman 2006). The prototypical selfregulated learner views learning as a systematic and S 2970 S School Motivation controllable process and accepts responsibility for achievement outcomes. Prototypical self-regulated learners approach tasks with confidence, diligence and resourcefulness, and proactively seek out information when needed, attempting to take the necessary steps to master it. They are metacognitively, motivationally, and behaviorally active participants in their own learning. From this perspective, the essence of the motivational state that drives engagement in an activity is believed to be the effective utilization of a range of metacognitive and self-regulatory learning strategies the student has for the task at hand. Research has demonstrated that self-regulated learners value the importance of effort and intrinsic interest in the task, appear to be high on selfattribution (i.e., they accept responsibility for successes and failures), and also report high self-efficacy (i.e., a belief in themselves as learners). Students’ selfefficacy beliefs can enhance their motivation, which in turn leads the students to continue learning in a self-directed manner (Zimmerman 2006). Research has also indicated that students who are academic high achievers practice a greater range of self-regulatory strategies, and more often, than low achievers. They may also make greater use of the full range of strategies such as self-evaluating, goal setting, and planning, keeping records, and monitoring and reviewing. Self-Determination Self-determination theory (SDT) posits three universal, fundamental, and broad ranging psychological needs which are considered to motivate goal-oriented pursuits. These needs are need for autonomy (i.e., selfdetermination in deciding what to do and how to do it), need for competence (i.e., developing and exercising skills for manipulating and controlling the environment), and need for relatedness (i.e., affiliation with others through prosocial relationships) (Deci and Ryan 2000). From the SDT perspective, the essence of the motivational state that drives engagement in an activity is believed to be the satisfaction of the three basic needs that give people the freedom to engage in self-determined activities. Thus, the theory postulates that students are likely to be intrinsically motivated to be engaged in learning activities when they are placed in a learning environment that supports satisfaction of their autonomy, competence, and relatedness needs. There are four types of behavioral regulation that can be ordered along a continuum between amotivation at one end and intrinsic motivation at the other end: external regulation, introjected regulation, identified regulation, and integrated regulation. External regulation occurs when students’ actions are regulated by external rewards, pressures, or constraints (e.g., a student who does an assignment with an aim to obtain teacher’s praise or to avoid parental confrontation). Introjected regulation occurs when students act because they think they should or would feel guilty if they did not (e.g., a student adopts this regulation when he studies primarily because he knows that he will get a bad grade and disappoint his parents if he does not). Identified regulation occurs when the regulation or value is adopted by the self as personally important and valuable (e.g., a student who willingly does extra work in a particular academic task because he believes it is important for his self-selected future goal of attending college or entering a particular occupation). Lastly, integrated regulation, which is the most selfdetermined form of behavioral regulation and loosely related to intrinsic motivation, occurs as a result from the integration of identified values and regulations into one’s coherent self (e.g., a student with two conflicting identifications of being a good student and a successful athlete who harmoniously integrates the two with each other; when this state is achieved, the student’s behavior is an expression of what is valued by and considered important by the student). The theory posits that students can gradually internalize extrinsic reasons for completing necessary, but uninteresting, tasks and learning activities and, thus, infuse agency into daily learning activities. Self-Concept The notions of self-concept and ▶ self-esteem are often used interchangeably. Researchers, however, argue that self-concept refers to descriptive information about oneself such as height, hair, skin color, ability in academics, sports, and so on, whereas self-esteem is the evaluative component of self-concept, which refers to how one feels about these objective qualities of selfdescription. Thus, in this regard, self-esteem reflects the components of self-concept judged to be important by a particular individual. The term self-concept is used in this discussion to cover both the descriptive and evaluative dimensions. School Motivation Research has consistently indicated that the more positive students’ academic self-concept, the higher their achievement. Individuals who have a positive self-concept are expected to be more motivated to perform particular activities than those who have a poor self-concept, and success in performing certain activities is believed to enhance self-concept. Hence, the relationship between self-concept and behaviors, particularly in terms of success and failure, is presumed to be reciprocal (Marsh and Craven 1997). From a selfconcept perspective, the essence of the motivational state that drives engagement in an activity is believed to be the student’s positive feelings about their capacities and aptitudes. Self-concept is formed through social interaction and social comparison. Feedback from significant others such as parents, siblings, teachers, and peers is influential in the growth of one’s self-concept. Social frames of reference indicate to us what our capacities and qualities are under particular circumstances. For example, on an objective criterion, some students may be quite good at mathematics, yet when they use others who are superior at mathematics as a frame of reference, they may develop a relatively negative mathematics self-concept (Marsh and Craven 1997). This is sometimes referred to as an external frame of reference. Furthermore, according to Marsh, we tend to compare our self-perceived skills in one area (such as mathematics) with our self-perceived skills in another (such as English) and use this internal, relativistic impression as a second basis for arriving at our self-concept in particular areas. This is often referred to as an internal frame of reference. Hence, students who are good at both mathematics and English may, nevertheless, have a more negative self-concept in mathematics if they perceive that they are better at English and vice versa. This explains why even slow learners differentiate their self-concepts across subjects and hold high self-concepts in some areas, even though their objective performance may be poor. This effect, called internal-external frame of reference, seems to be universal among students from a wide range of cultures. There is also a relationship between a student’s selfconcept, average school performance, and the student’s school achievement. This relationship is often referred to as the big-fish-little-pond effect. That is, it is often better for a bright student to be a “big fish” in a “little S 2971 pond” (i.e., doing well among a mixed-ability group) than to be a “little fish” in a “big pond” (i.e., performing at an average level in a high-ability group). In the former case, it is easier for students to establish and maintain positive feelings about their academic accomplishments, which serve to reinforce further academic pursuits. In selective educational environments, where the average ability of students is high, it is more difficult to establish and maintain these positive feelings, and high-ability students may choose less demanding coursework and have lower academic self-concepts, lower achievement scores, lower educational aspirations, and lower occupational aspirations than similar students in nonselective educational environments. Important Scientific Research and Open Questions There are a number of contemporary cognitive theories of motivation that attempt to provide insights into and explanations of the dynamics of school motivation. No one of these theoretical perspectives is sufficient, in and of itself, to explain the complex nature of school motivation. Nevertheless, drawing the various perspectives together may give an enhanced capacity to educators to facilitate the active engagement of students in learning. Further research should be directed at “harmonizing” the various cognitive theories with the purpose of examining whether there are some underlying principles that might characterize the essence of motivation from a cognitive perspective. Although used to guide instructional practices in many non-Western settings, most theories of school motivation are based upon Western theorizing. There is a need to consider whether these theories have validity and applied value in non-Western settings. It is also important to develop “indigenous” theories of school motivation that might be more heuristic in nonWestern educational contexts.

Rather, one should view these terms and their connections as suggesting there are some salient qualities about learning experiences that emerge at the intersection of art and science. Even this, however, runs the risk of an overly prescriptive definition. Scientists, artists, philosophers, historians, and psychologists have written about these terms but there is an emerging unified discourse that draws mainly from the aesthetic theory of (John Dewey 1934). From this one might define these learning experiences as those which transform the perceptions of the learner, yield emotional qualities similar to those experienced when viewing great art, and educate conceptual understanding of important subject matter. These kinds of learning experiences may also be described as transformative learning experiences or aesthetic experiences. Theoretical Background Consideration of connections between art and science is not new but recognition of the unique nature of these connections and their role in facilitating powerful learning experiences is an emerging field. Philosophers have long recognized that science and art share some underlying values such as parsimony, form, symmetry, pattern, and unity. Similarly, scientists have acknowledged the role these values play in judgments about science and in pursuit of scientific inquiry (Fischer 1999). The science education community has begun to see efforts to build theoretical models, pedagogical strategies, and generate empirical evidence to systematically support these linkages in ways that promote powerful learning experiences. The best-articulated lines of research in this field follow (Dewey 1934) and the translation of Deweyan aesthetic theory into psychological and educational principles (Jackson 1998). Emphasis is on aesthetic experience and transaction between experiencer (person) and experienced (world). This transaction is characterized by both doing and undergoing, and acting and changing. It is infused with appropriate emotion, bears anticipatory qualities, and consummates fully as opposed to ending abruptly. Scholars in this area have used these key aesthetic constructs as a roadmap for the articulation of educational theories that yield similar powerful learning experiences. S 2973 Key constructs include expansion of perception, motivated use, and experiential value. Expansion of perception refers to seeing anew through important and powerful scientific and artistic lenses. Powerful learning experiences at the intersection of science and art yield new ways of seeing the world and the learner, and his or her position in the world. Motivated use refers to the desire to utilize or exercise newfound knowledge, skills, or dispositions. Experiential value refers to finding enjoyment in what new learning provides or how it enriches ordinary experience. Similar conceptual elements may be described as transformative, aesthetic experiences, or aesthetic understanding. Pedagogical models for facilitation of learning experiences that link science and art through aesthetic experiences include modeling expansion of perception, increased value, interest, and positive attitude toward science, art, and new learning. Curricular structures that focus on important and powerful subject matter learned through metaphor, promotion of awe and wonderment, use of sublime, story-telling, and powerful imagery is also suggested. A key Deweyan construct here is that of the idea (Dewey 1933). An idea can be viewed as a lens or a plan of action that illuminates and fosters powerful, artful learning. Important Scientific Research and Open Questions Research related to science, art, and learning experiences may be spread across a wide range of literatures including those in educational psychology exploring motivation, engagement, interest, attitude, flow, transfer, efficacy, and identity and may derive from cognitive conceptual frameworks focused on conceptual change or socio-cultural frameworks focused on situative understanding and applications of new knowledge in authentic settings. In teacher education literature only a few key references exist describing pedagogical strategies useful for facilitating powerful learning experiences at the intersection of art and science (Pugh and Girod 2007; Wickman 2006). To date, it is fairly well established that teaching in ways that link art and science can have a positive impact on student conceptual understanding, reduce forgetting, increase motivation and engagement with science, facilitate positive identity affiliations toward science, and promote transfer of learning to out-of-school environments (Girod et al. 2010; Pugh et al. 2010). S 2974 S Scientific Curiosity A wide range of open questions remain including descriptive studies that explore the prevalence of naturally occurring learning experiences at the intersection of art and science both in schools and beyond as well as deep analyses of the psychological nature and educational value of these kinds of learning experiences. Correlational studies remain necessary to explore relationships between a wide range of contextual and learner-level variables and outcomes associated with science, art, and learning. Causal studies are needed to explore high valence pedagogical strategies, curricular models, and to establish empirically validated theoretical linkages between constructs of interest. Measurement studies are needed to further demonstrate the quality, quantity, and predictive validity of learning experiences at the intersection of science and art. Much work remains to be done in this field both from the theoretical perspectives described in this entry and from beyond.

More specifically, a script is a predetermined, stereotyped sequence of actions that define a well-known situation. As do schemas, scripts also contain slots and default values that can be filled. The resulting structure is an interconnected whole, and what is in one slot affects what can be in another. The classic example of a script involves the typical sequence of events that occur when a person dines in a restaurant: finding a seat, reading the menu, ordering drinks from the staff . . .. Scripts were developed in the early AI work by Roger Schank and Robert P. Abelson and their research group. These authors basically assume that procedural knowledge from everyday situations is stored in the human mind in the form of scripts. They are very similar to frames, except that the values that fill the slots of a script must be strictly ordered. Understanding a familiar situation involves activating a stored script of this situation.

Traditionally, ▶ formal learning is defined as learning that happens at a fixed time following predefined curricula or plan. Informal learning, on the other hand, means a mode of learning driven by self-interest outside of school environment, and is emergent in nature. Theoretical Background Seamless learning is marked by the continuity of learning experiences across different scenarios or contexts. The challenge is to enable learners to learn whatever they are curious about and to seamlessly switch between different contexts, such as between formal and informal contexts, between individual and social learning, and by extending the social spaces in which learners interact with each other. Technology plays an important role in mediating the switching between these different spaces. Our students live in a digital world, and the use of technologies such as instant messaging, video sharing, photo sharing, social network tools, podcasting, and blogging are integrated into their lifestyles. Smartphones are used not only for making calls, but S 2976 S Seamless Learning for taking pictures and uploading them to shared spaces, creating mobile blogs, or accessing the web on the move. The use of these technologies facilitates communication, collaboration, sharing, and learning in informal settings with their peers, friends and family, unbounded by time and location. Students spend more time in such “informal” settings than “formal” settings in the school. One of the fundamental challenges for the twenty-first century learners is that there is a need to understand not only what they learn, but how and when they learn. A deep understanding of how learners learn informally can be used to inform the facilitation of formal and informal learning practices. A seamless learning environment bridges private and public learning spaces where learning happens through both individual and collective efforts and across different contexts (such as in-school vs afterschool, formal vs informal, physical world vs. virtual reality or cyberspace). When thinking about learning scenarios in schools and other places of learning, people often conjure up mental images of a classroom with all seats facing the teacher. The presumption is that learning happens at fixed times and fixed places. However, with the diffusion of technology, the notions of place, time, and space for learning have changed. The learning space is no longer defined by the “class” but by “learning” unconstrained by scheduled class hours or specific locations. With mobile technologies at hand, students can learn seamlessly – both in classroom and out of classroom, both in school time and after school time. While learning can be facilitated or scaffolded by teachers or peers, at other times it could be studentinitiated, impromptu, and emergent. Personal, portable, wirelessly networked technologies will become ubiquitous in the lives of learners. With quick and ready access to these technologies, we enter into new phase in the evolution of technology-enhanced learning (TEL), characterized by “seamless learning spaces” and marked by the continuity of learning experiences across different scenarios or contexts, and emerging from the availability of one device or more per student (“one-to-one”) (Chan et al. 2006). These developments, supported by theories of social learning, situated learning, and knowledge construction, will influence the nature, process, and outcomes of learning. One-toone TEL will push the frontier of technology use in formal and informal learning. The ingenious, emergent, or pervasive use of one-to-one devices in some usage contexts may be close to the tipping point in terms of effecting fundamental shifts in the ways students learn in schools and outside of schools. Previous ▶ mobile learning research, however, has typically focused on either formal or informal settings and failed to examine the integrated and synergetic effects of linking these two contexts or environments of learning (Sharples 2006). Mobile technology has the potential to mediate seamless learning, challenge the traditional dichotomous distinction between formal learning and informal learning by creating seamlessly connected learning experiences (Looi et al. 2010). While research on cognition and learning during the past decades has emphasized the importance of linking learning in the classroom and learning in the field, the dominant characteristic of school learning still has a strong focus on individual cognition, pure mental activity without tool use, and overly context-general learning. Moreover, there are tensions between formal learning, which is based on fixed curricula enacted in classroom environments, and informal learning where learners are participating in intentional or unintentional experiences outside school settings. We believe that the two forms of learning should not be seen as dichotomous and conflicting situations (Sharples 2006). Instead, by utilizing the affordances of mobile technology, we can bridge the gap between formal and informal learning, and encourage students to learn in naturalistic settings for developing context-specific competencies. A suitable lens for interpreting seamless learning activities is the distributed cognition (Hollan et al. 2001). In a seamless learning environment, learning takes place through individual learning in private spaces, collaborative learning in public spaces, and interactions with the environment and articfacts across time, context and physical or virtual spaces mediated by technology (Sharples 2006; Chan et al. 2006). Distributed cognition can provide a framework for understanding how learning occurs through the interactions of students, artifacts, and the environment mediated by technology over space and time. Though early studies aim to understand how teams comprising individuals with different skills or assigned roles function together to achieve a specific task, the notion of distributed cognition is applicable to learning as students’ expertise Seamless Learning and interactions are also distributed in the classroom (Pea 1993). Hollan et al. (2001) proposed three principles in which cognitive processes occur: They are distributed: (1) across the members of the social group; (2) over time; and (3) coordination between material or environmental structures in the system. Learners interact with the environment in the community, artifacts, activity, and space through the cognitive tools to form a joint learning system (Kim and Reeves 2007). Our seamless learning framework is based on our identification of components in a seamless learning environment and the theory of distributed cognition, namely, space, time, context, community, and tools. Space: Seamless learning suggests that the learners can move seamlessly between different spaces – physically and virtually. The physical space where students use to conduct inquiry with the mobile device can be used as a resource for learning (Squire and Klopfer 2007). Time: Over time, when learners operate on artifacts, collaborate with peers, teachers and experts or make discovery, they acquire and construct knowledge. Time can play an important role in shaping and evolving inquiry, and developing deeper understanding as they interact in a seamless learning environment. Context: The context of the designed or emergent activities in which the learner is engaged and the environment in which these activities occur impacts their learning, application, and plans. Community: The community in a seamless learning environment comprises learners, teachers, and domain experts. Individual learners in a seamless learning environment can move from individual learning to community learning and from private cognition to public cognition and vice versa. Tools: As students use the mobile device to record data, capture images, upload data to the online portal and reference them, mobile devices and online portal become cognitive tools where they are able to offload tasks, recall information over time, and modify their initial thoughts. Important Scientific Research and Open Questions A large research gap exists in the area of bridging formal and informal settings in order to construct a seamless learning environment. There is also a lack S of longitudinal studies to explore the affordances of such learning environments in promoting twenty-first century knowledge, skills, and positive attitudes toward learning. Regarding the use of methodological issues for seamless learning research, the design experiment methodology is typically used to design and implement seamless learning research. The choice of design experiment is ideal as this method stresses upon systemic thinking on the interdependence of design elements, and the importance of examining emerging issues through progressive refining processes (Collins et al. 2004). More importantly, in order to design sustainable twenty-first century learning environments, as researchers, we need to make a commitment to conduct sustainable research, and this necessitates the use of theoretical and methodological lens that are congruent with the goals of this research. An important consideration in seamless learning research with mobile devices is to understand the enactment of learning activities, which unfold in various situations. Previous research that examined the use of mobile devices in informal settings has shown both promises and challenges (e.g., Sharples 2006; Squire and Klopfer 2007). Mobile technologies with portability, connectivity, and versatility enable learning to be ubiquitous in and out of classrooms, provide potential opportunities for collaborative learning, and enrich learning experiences with the support of technologies. For instance, Price and Rogers (2004) suggest that mobile devices can be used to help students explore digitally augmented physical environments where contextually relevant information and resources are provided. In such digitally enhanced settings, students using mobile devices can explore, capture, and manipulate both physical and virtual (or digital) objects for active understanding. From design and research perspectives, however, studying mobile learning in informal settings is challenging because students are “on the move” across different modes of space (both physical and virtual) and time. Thus, an ethnographic approach (Anderson-Levitt 2006) can be integrated into design research for observing how students are engaged in informal and formal learning settings in their interaction with their handheld devices, peers, teachers, and other people in their learning community. Studies that focus on examining short-lived learning experiences such as user satisfaction surveys and 2977 S 2978 S Seamless Learning strict comparisons of test measures, fail to provide comprehensive perspectives on learners’ meaningful experiences across settings over time. Indeed, mobile learning researchers face methodological challenges in terms of the scales of space and time (Lemke 2000): how to record learning across different physical spaces and different technological media, and how to examine learning in the longer timescale including informal learning outside school contexts. However, because of the novelty of the proposed study, there is no “off-theshelf ” methodology for us to adopt. For data collection, the learning trajectory of students using mobile technologies for learning across subjects and over time needs to be recorded. Possible data sources include but are not limited to observations, field notes, audio and video recordings, interviews, student artifacts, self-documentation by participants, and log files on computers. There are also methodological issues involved in observations such as distorted behaviors and artificial tasks (Gardner 2000), and also ethics and privacy issues for observing students outside school settings. Researchers should aim to minimize potential problems by employing unobtrusive methods such as log files, which provide an authentic, time-efficient means of recording student learning behaviours. In situ sampling of the students’ daily experiences with mobile devices can be captured using the experience sampling method (ESM) (Csikszentmihalyi and Larson 1987). This method may provide us with a better understanding and natural assessment of how students are engaged in informal learning everyday with mobile devices as they are using it. By employing ethnographic methods, in situ selfreport procedures, constant comparisons, and sustained observations as well as analyzing quantifiable measures, we can critically examine how learners use mobile technology across subject areas and how different user experiences and motivation levels affect learning over time. Important assessment issues loom in the space of seamless learning. With students’ use of devices for informal learning, what are the indicators of learning? Or what accounts for learning at the first place. One well-cited definition of learning is “changing through experience . . . acquiring relatively permanent change in understanding, attitude, knowledge, information, ability, and skill through experience” (Wittrock 1977, p. ix). To us, the more important change might be in student value and character change, which can gauge students as lifelong learners and persons-to-be. Therefore, challenges exist in assessing the skills, knowledge, identity, values, and epistemology (Shaffer 2007) as students become adept in using the mobile device as routine practice in the classroom and out of the classroom. One approach for assessment in seamless learning environment is to adopt a preparation for future learning (PFL) framework (Bransford and Schwartz 1999) to emphasize assessment for learning. The purpose of PFL is to promote deep understanding and knowledge transfer in multiple contexts, and mobile devices can act as a mediating tool enabling such learning transfer. Traditional approaches of assessment focus on measuring student abilities to directly apply their previous knowledge to new problems without help or resources. This type of direct application, however, fails to measure the zone of proximal development (Vygotsky 1978), that is, students’ potential abilities to learn in knowledge- and resource-rich environments. In seamless learning research, researchers can explore different sequencing of learning conditions such as (a) formal vs. informal learning, (b) intentional vs. unintentional learning, and (c) abstract context-general vs. and concrete context-specific settings in order to identify enabling conditions that better prepare students for future learning. The motivation for promoting informal learning probably first started from the training work place skills because it involves obvious costs. Another term we have not mentioned is “nonformal” learning, which refers to learning that happens in formal learning settings but is not tested or assessed in traditional ways. So, formal, informal, and ▶ nonformal learning are all learning. As we have argued, learning can happen at any situation and context. However, how to capture learning that is not planned, not fixed and probably without validated instruments to measure, and usually individualized poses great challenges to learning science researchers. We need also to collect multiple data sets over time for triangulation purposes. When considering the linkage between formal and informal learning, we might be able to infer the effectiveness of informal learning through assessing the conceptual equivalents specified in formal curricula. On the other hand, performances in informal settings can be a result of formal learning in terms of preparing the students for future learning. Second Language Acquisition Studying school-based learning and following through with after-school learning will enable the exploration of a theory of mobile learning for seamless learning tied strongly to empirical evidence. For instance, the PFL perspective can be adopted to frame the use of mobile devices in informal settings as enabling students to familiarize with a problem and its context before in-school learning of formal concepts. Our findings will be used for further understanding of the application of the PFL framework, as well as providing evidence of the efficacy of different sequencing of formal and informal learning activities. Research into seamless learning needs a strong focus on pedagogy, professional development of teachers, codesign of lessons with teachers, a design research perspective, and low-cost affordable mobile learning devices. International collaboration and innovation can contribute toward the broader research agenda. By organizing and sharing information across design experiments in diverse settings, a collaboration of researchers can more rapidly and systematically explore the design space (Hawkins 1997). For instance, the same-grade classrooms across different countries can implement mobile learning devices for all subject areas, allowing a broad examination of solutions and challenges. By collaborating across the globe, researchers could take advantage of different student device preferences, exchange curriculum ideas, understand cultural differences, and better address issues of scale.

Second Language Acquisition ▶ Second Language Learning 2979 S 2980 S Second Language Learning Second Language Learning ANGELIKA RIEDER-BÜNEMANN English Department, University of Vienna, Vienna, Austria Synonyms Foreign language learning; L2 acquisition; Second language acquisition Definition Second language learning (SLL) is concerned with the process and study of how people acquire a second language, which is often referred to as L2 or target language, as opposed to L1 (the native language). Generally, the term second language in this context can refer to any language (also a third or fourth language) learned in addition to the native language. However, second language learning would be contrasted with a bilingual learning situation, in which a child acquires two languages simultaneously (e.g., when the parents speak two different languages). We only speak of second language acquisition if another language is acquired after the first language. The terms learning and acquisition are frequently treated as synonyms in the literature. Some researchers, however, distinguish between acquisition and learning, stating that acquisition refers to the gradual subconscious development of language abilities by using the language naturally (similar to the process of children acquiring their first language), whereas learning refers to the conscious process of accumulating knowledge of a language, typically as the product of formal instruction (Krashen 1982). In the same vein, the term second language learning is sometimes associated specifically with the learning of languages through formal instruction, while the term second language acquisition is commonly used as a generic cover term to refer to learning a target language in all situations, including the classroom. Another relevant term in this context is foreign language learning, which some researchers use to differentiate between learning environments. In their view, foreign language learning refers specifically to the learning of a nonnative language in the environment of one’s native language, while the term second language acquisition to them refers to language learning in the country where this language is spoken (which may or may not take place within a classroom setting). Not all researchers, however, agree with this distinction. Theoretical Background The study of second language learning/acquisition is a fairly recent phenomenon, belonging to the second half of the twentieth century. In the various periods of SLL research, there were conflicting views about the nature and development of the learner’s language knowledge, depending on the prevailing linguistic theory of the time (for a detailed discussion, see Ellis 2008). Around the 1950s, the established theory was ▶ behaviorist learning theory, which saw language learning, like any other learning, as a habit formation. Most scholars claimed that knowing a language means knowing a number of items and their potential arrangements, and a second language learner was seen as exhibiting imperfect knowledge of these items and rules, with gaps in L2 knowledge naturally filled by the grammar of the learner’s L1. Consequently, it was predicted that the main cause of errors in the L2 were interferences of the L1 (called negative transfer). With a method called contrastive analysis, the linguists of the time contrasted the L1 and L2 language systems and looked for potential areas of difficulty due to differences between the language systems. As research showed, however, not all learner errors can be attributed to the phenomenon of transfer. Rather, learners appear to be actively involved in constructing their own rules, and behaviorists were criticized for ignoring the creative side of language. Subsequently, researchers’ attitude toward learner errors changed, and contrastive analysis was replaced by error analysis, where errors were not seen as examples of non-learning from the language norm any more but were regarded as examples of learners’ active testing of hypotheses. In the 1960s and 1970s with Noam Chomsky, a new research paradigm emerged, stressing the innate properties of the human mind that shape language learning, which provided a ▶ mentalist theory of language learning. With his innateness hypothesis, Chomsky (1965) claimed that humans possess a faculty for learning languages referred to as Language Acquisition Device (LAD), which is equipped with Universal Grammar (UG), i.e., principles and parameters underlying all grammars of all languages. Drawing directly from these Second Language Learning mentalist views of L1 acquisition, researchers then claimed that the learner does not move from L1 to L2 in an incomplete language system, but that there exists a learner language system called interlanguage (Selinker 1972), which is a dynamic system independent of L1 and L2 with rules of its own. A question which has frequently been considered by second language researchers is whether we still have access to the LAD postulated by Chomsky in L2 acquisition. Basically, four possibilities have been proposed: the “no-access position” argues that L2 learners acquire the L2 grammar without any reference to UG but through other faculties of the human mind, whereas the “complete access position” claims that L2 learners learn in exactly the same ways as L1 learners. In the “partial access position,” then, L2 learners have access to UG through what they know of the L1, starting with L1 parameter settings rather than with the initial neutral state, while in the “dual access position,” L2 learners have continued access to UG, but also have access to a general problem-solving module, with both systems competing in L2 acquisition (see Ellis 2008). Since the 1980s, our understanding of the many facets of second language learning has been greatly enriched by perspectives from related disciplines. Two theories which have become particularly popular recently here are connectionism (viewing SLL from a neuropsychological perspective) and Vygotskyan learning theory (operating within a sociocultural framework; for details and a survey of SLL theories see Mitchell and Myles 2004). ▶ Connectionism, which is cognitively oriented, is not a particularly new approach, but progress in computer technology has increased its popularity since most studies involve hypothesis testing via computer simulation. Like other cognitive theories, it sees second language learning/knowledge as similar to other types of learning/knowledge (in contrast to a linguistic theory, which claims that linguistic knowledge is unique). Here, the brain is conceived as consisting of neural networks, with (language) learning occurring on the basis of associations, by which links between information nodes become strengthened or weakened. Thus, connectionism differs from other theories insofar as it does not believe that language acquisition involves rule learning, but postulates associative processes instead. Vygotskyan ▶ sociocultural theory (a general theory of learning associated with Lev S. Vygotsky S 2981 (1896–1934) applied to SLL by James Lantolf), like connectionism, claims that language learning and general learning are subject to identical mechanisms. In contrast to cognitive approaches, however, it argues that social interaction plays a fundamental role in the development of cognition. While sociocultural theory rests on a variety of theoretical principles, its core construct is that of mediation, i.e., that mental activity in general and learning in particular is a process which is mediated through mental tools (e.g., language) and through social interaction; the theory thus rejects the conventional distinction between social and psychological components of cognition. Shifting the focus from SLL theories to the language learner and learning results, a characteristic phenomenon frequently observed is that an L2 is rarely acquired to a degree that is comparable to native-speaker proficiency in the L1, and that the results achieved vary widely; in most cases the process of learning will stop at some point, and learner language will fossilize at a stage when it still contains certain features which do not correspond to the target language. One goal of SLL research is to identify the external and internal factors determining why language learners acquire language in the way they do and why different proficiency levels are attained by different L2 learners. Several external and internal factors appear to come into play here: ● The social context forms a decisive external factor. Even in first language acquisition, social factors concerned with the relation of child and caretaker will play a role. In second language learning, the social context will have even more importance because it is increasingly complex. On the one hand, it will play a role in influencing the attitude of the language learner toward the second language, while on the other hand, it will also determine the social provision of learning situations and opportunities. ● ▶ Motivation represents an internal factor which may be influenced by the social context, since the initial motivation to learn the L2 will be created by the attitude of the learner toward the language and/or the community. Two main types of motivation commonly distinguished here are integrative motivation (i.e., language learning due to a desire to integrate with the L2 community) and instrumental motivation (i.e., language learning in order to S 2982 S Second Language Learning receive a good grade, no particular interest in communication). In addition to this general motivation to learn, motivation can also arise from success in the learning process, and can thus be both a cause and the result of success. ● Personal characteristics of the language learner will also have an influence on the learning process and outcome. Age will play a role, insofar as adults appear to be less likely to achieve native-like pronunciation in the target language. Another potential influencing factor is the learner’s general ▶ personality, which manifests itself in factors like the degree of anxiety he/she exhibits. The particular learning style and the ▶ learning strategies the learner favors and develops will also be an influence in this context. Finally, apart from age and personality, learners will also vary with regard to their ▶ language aptitude, i.e., their natural disposition for learning an L2. ● The amount and characteristics of the learning opportunities form another external influencing factor which is crucial for the acquisition process. Whatever the language learner brings to the task in terms of aptitude, motivation, etc., the outcome of language learning depends to a large extent on the amount and kind of exposure to the target language. Here we can firstly differentiate learning opportunities in terms of time of exposure to the language, and secondly distinguish between different kinds of learning, i.e., formal instruction vs. natural acquisition. Both of these variables will influence the route and rate of second language learning. Important Scientific Research and Open Questions Since the initial stages, SLL research has developed into an independent and interdisciplinary field, with investigations becoming increasingly diverse and sophisticated. Competing theories of second language learning exhibit substantial differences since researchers approach the question how second languages are learned from a wide range of perspectives and research backgrounds, such as linguistics, psychology, or education. Apart from differences related to the scientific field of origin, theories differ for instance in the type of learning they cover (e.g., naturalistic vs. instructed acquisition), in research approach (e.g., inductive vs. deductive reasoning), or in the theory’s core elements (e.g., the role attributed to influencing factors). Although all theories have in common that they aim at explaining how second language learning works, the field of SLL is still struggling with the multitude of competing explanations (Mitchell and Myles 2004). Another open question in this context concerns the relation between research on second language learning on the one hand and language teaching on the other. To this end, researchers are still debating in what way and to what degree second language learning research actually impacts on second language teaching. While early SLL research was frequently pedagogically motivated, much of the current research is no longer directly concerned with language teaching issues. Nevertheless, we can assume that research results are at least indirectly relevant to language pedagogy, since second language learning is the process that language teaching aims at facilitating. Various parallel methods exist for teaching a foreign language, reaching from the early grammar translation and audio-lingual method to the communicative approach, which are usually conceptualized on the basis of a specific view of what language is, how it is learned, and what conditions facilitate learning. Nevertheless, the problem of a gap between SLL research and language pedagogy due to the former’s interest in technical knowledge, in contrast to the latter’s concern with practical knowledge, is frequently addressed in the literature, and attempts are made to bridge this gap (Ellis 1997).

Also known as dual-task techniques, secondary task measures of cognitive effort assume that there is a limit to the learner’s cognitive capacity, and that when a great deal of cognitive capacity is consumed by the primary task, less capacity is available to devote to the secondary task. The difference in reaction time to the secondary task between a baseline condition, where the learner only responds to the secondary task, and the experimental condition, where the learner performs both the primary and secondary task, is assumed to be reflective of the amount of cognitive effort expended on the primary task. Second-Order Factor Dimensions of personality can be analyzed at different levels of generalization. In ordinary factor analysis observed (measured) variables are grouped into one or more first-order factors corresponding to a first level of generalization. Second-order factors are clusters of correlated first-order factors and correspond to a higher level of generalization. There are also third-, fourth-, and higher-level factors. Selection Task The Wason selection task is one of the most famous tasks in the psychology of reasoning. It is a logic puzzle in which subjects must assess the truth or falsity of a general rule from specific instances. In particular, the subjects face a problem of optimal data selection because they must decide which of four cards (p, not-p, q, or not-q) is likely to provide the most useful data to test a conditional rule, if p then q. The “logical” solution is to select the p and the not-q cards. Oaksford and Chater (1996) argue that this solution presupposes a falsification of a kind described by Popper in which only data which can disconfirm hypotheses are relevant for the selection task. However, due to the fact that they implement rational analysis using a Bayesian approach, Oaksford and Chater consider selection tasks as inductive rather than deductive reasoning tasks.

WEISS Department of Psychology, American University, Washington, DC, USA Synonyms Cue-to-consequence learning; Selective attention; Stimulus–reinforcer interaction S 2984 S Selective Associations Definition Selective associations have been one of the more intensively studied examples of animals’ predispositions to learn “more” about certain contingencies than others. The differential effectiveness of a stimulus in controlling responding when it is paired with different reinforcers is the evidence for one kind of selective association, a “stimulus–reinforcer interaction.” Theoretical Background The study of conditioning and learning is concerned with the associative processes underlying learned modifications of behavior. In classical conditioning, these modifications are produced by contingencies arranged between a stimulus and an outcome. In operant learning, they are produced by contingencies arranged between a response and an outcome. Traditional behavior theory concentrated on the discovery of general laws of learning where stimuli, responses, and reinforcers might be viewed generically, with different instances within any class of events interchangeable. This equipotentiality assumption of general-process learning theory has been brought into question by findings demonstrating what appear to be biological constraints on learning and the associability of various events and has continued to be a source of debate and investigation (Domjan 1983). One of the early examples of a biological constraint on instrumental learning showed that racoons could only be taught to drop tokens into a slot for positive reinforcement (food) with extreme difficulty, if at all. Innate patterns of behavior seem to supercede the contingencies of reinforcement imposed by the trainer. Does this mean that the empirical law of effect should be abandoned? Not necessarily. If more than the experimenter-defined aspects of the situation are considered (token release for food), what was called “misbehavior” can be explained in terms of stimulus–reinforcer contingencies relevant to obtaining and consuming food. The racoon’s behavior is consistent with generally applicable, if more complex, general learning principles, but the “influence . . .of. . .the conditioned motivational state in which the instrumental conditioning was conducted and the motivational state that was conditioned by presentations of the reinforcer [must be considered]” (Domjan 1983, p. 264). From this perspective, “misbehavior” and other apparent biological constraints on learning have strengthened general-process theory by encouraging it to deal functionally with the complete learning situation. Generalizations thus developed are concerned with more detailed features of a learning situation, rather than the simplistic interchangeability of cues, responses, and reinforcers (Domjan 1983). The present entry will relate the phenomenon of “selective associations” to general learning principles. Important Scientific Research and Open Questions In Garcia and Koelling’s (1966) seminal selective association experiment, a compound conditioned stimulus (CS) consisting of a taste and an audiovisual stimulus was paired with a lithium chloride unconditioned stimulus (US) in one group of rats and with an electric shock US in another. In testing, the taste and the audiovisual stimulus were presented separately. The taste stimulus controlled a stronger conditioned response (CR), suppression of drinking, when lithium chloride was the US, while the audiovisual stimulus controlled a stronger conditioned response when electric shock was the US. This first demonstration of a selective association revealed that the choice of the CS used in conditioning experiments was not as arbitrary as believed – and that experimental outcomes might critically depend on the particular combinations of CSs and USs used. More specifically, it showed that when a set of stimuli have been given equal opportunity to control a response, the US may determine which stimulus is most effective. Such instances of selective associations have also been called “stimulus–reinforcer interactions” and “cue-to-consequence learning.” Garcia and Koelling’s (1966) experiment employed the conditioned taste aversion paradigm wherein nausea, caused by lithium chloride, following a novel flavor might be considered intrinsically related. However, selective associations have been demonstrated in more traditional and often encountered learning paradigms in pigeons by Foree and LoLordo (1973) and in rats by Schindler and Weiss (1982). In a discrete-trials operant procedure, Foree and LoLordo trained different groups of food-deprived pigeons to depress a foot treadle in the presence of a 5 s compound stimulus consisting of a 440 Hz tone and a red houselight. For one group these treadle presses avoided electric shock, and for the other group they produced grain. When the pigeons were effectively avoiding shock or earning food in the Selective Associations compound, the tone and light were presented separately as a test of control by the stimulus elements. After appetitive training, the red light exerted strong control over treadle pressing, while few responses were emitted during the tone. By contrast, after training with shock avoidance in the compound, the tone controlled more treadle pressing than the light. This “stimulus– reinforcer interaction”, that was systematically replicated in pigeons by Weiss et al. (1993b), is plotted in the right frame of Fig. 1. Schindler and Weiss (1982) expanded the generality of this selective association phenomenon over species to rats and to free-operant avoidance (FOA) contingencies. In a tone-plus-light (TL) compound, one group of rats bar pressed to produce food on a variable-interval (VI) schedule and another pressed to postpone shock on an FOA schedule. In the absence of tone and light (T L), responding had no scheduled consequences [extinction (EXT)]. When the subjects were responding at least ten times as rapidly in TL as in T L, a test was administered to assess the degree of control exerted by the tone and light elements of the compound training stimulus. Consistent with the findings of Foree and LoLordo, on a stimulus–element test (a) the light gained almost exclusive control of responding when bar pressing was maintained by Schindler & Weiss (1982) 80 60 Tone 40 Light 20 100 Foree & LoLordo (1973) 80 Tone 60 40 Light 20 0 0 Food 2985 food, and (b) the tone gained considerable control under the shock-avoidance schedule (see left frame of Fig. 1). A similar selective association was revealed over these two species even though pigeons are clearly more visual animals than rats. Selective associations appear to be a basic attentional process that generalizes over species and experimental conditions. Unfortunately, in these studies reporting stimulus–reinforer interactions in traditional operant (Foree and LoLordo 1973; Schindler and Weiss 1982) and classical [see Shapiro, Jacobs and LoLordo (1980) cited in Weiss et al. (1993a)] situations, the physical nature of the stimulus responsible for reinforcement (food and shock) was covarying with what might be considered the conditioned hedonic value that would have been conditioned to the TL compound. Therefore, whether these selective associations were determined by the physical nature of the reinforcer or the hedonic state they produced remained to be determined. In both, the Foree and LoLordo and the Weiss and Schindler experiments, when the subjects were working for food during TL they were in a hedonically positive condition that would be preferred over the nonreinforcement associated with the absence of these stimuli. In comparison, TL would have become % Element Responses % Element Responses 100 S Shock Food Shock Group Selective Associations. Fig. 1 Left frame: The percent of total element responses emitted in tone (filled circles) and in light (open circles) by rats that had been trained by Schindler and Weiss (1982) in tone-plus-light to earn food on an intermittent schedule or to avoid shock. Right frame: Same measure for the pigeons of Foree and LoLordo (1973, adapted from their Fig. 3). Responding came primarily under the control of the light when food was the reinforcer and tone when shock avoidance was the reinforcer. Because different classes of reinforcer, appetitive or aversive, maintained responding in both groups of each study, these profiles have been termed “stimulus–reinforcer interactions” S 2986 S Selective Associations a hedonically negative (nonpreferred) condition, compared to shock-free T L, when TL was associated with shock avoidance. This means that in these studies reporting “stimulus–reinforcer interactions” food and shock were confounded with relative hedonic value conditioned to the TL compound stimulus that would be revealed by schedule-component preference. Following this train of reasoning, one could contend that when TL signals a preferred condition, the light will be selectively attended to and when it signals a nonpreferred condition the tone will be attended to – what might be termed a “stimulus–preference interaction” In this analysis, attention is related to a contingency-generated psychological state – rather than food- or shock-related situations in particular that are just one means of creating these states. Weiss et al. (1993a) eliminated this covariation by creating TL compounds of positive and negative hedonic value (i.e., positive stimuli the organism is drawn toward or negative stimuli it is repelled from, respectively) using only appetitive contingencies. Konorki’s appetitive–aversive interaction theory of motivation, that proposed the affective equivalence of excitors and inhibitors of contrasted affective value (appetitive vs. aversive) was their point of departure. According to Konorski, (1) a stimulus signaling the absence of food has many negative properties in common with aversive stimuli such as electric shock, and (2) a stimulus differentially associated with the absence of shock has positive (attractive) properties that parallel those produced by appetitive reinforcement. What one is, therefore, concerned with here is not the physical character (e.g., food or shock) of the event ultimately responsible for the conditioned association, but rather, functionally, with whether the organism is drawn toward (positive) or repelled from (negative) the situation associated with the TL compound. Operationally, the organism will work to produce the former and terminate the latter condition. In the Weiss et al. (1993a) experiment, bar pressing in TL was ultimately maintained by food in two groups of rats but in a manner that broke the covariation described above between the physical nature of the reinforcer and the conditioned affective value of the TL compound. To accomplish this, contingencies were arranged such that, relative to T L, TL became hedonically positive (a conditioned appetitive excitor) for one group and hedonically negative (a conditioned appetitive inhibitor) for the other. This latter group was meant to be hedonically comparable to the groups reported by Foree and LoLordo (1973) and Schindler and Weiss (1982) where shock-avoidance-associated TL was a conditioned aversive excitor. To accomplish this, both Weiss et al. (1993a) groups responded in TL and ceased responding in T L, just as the food and shock groups presented in Fig. 1 did. However, one group (TL+) earned all their food reinforcers on a VI schedule in TL for bar pressing while T L was associated with extinction (EXT), like the food group in the Schindler and Weiss (1982) study. In contrast, their TL group received reinforcers only in T L, where responding ceased because it delayed food delivery. But, they were on a chain schedule wherein bar pressing in TL produced, on a VI schedule, the T L component wherein all food was received. This was an implicit measure that TL was the nonpreferred component because the rats were working therein to produce T L. After the subjects of the TL+and TL groups were brought under stimulus control, with responding in TL indistinguishable over groups (see Fig. 1 in Weiss et al. (1993a)), they received a stimulus–element test. On this test, tone and light were presented separately for the first time to determine which modality controlled primarily responding in TL (auditory or visual). All rats in the TL group emitted more responses in the tone than the light test element, while no rat in the TL+group did this. On average, rats in the TL+ group emitted 65% of their element test responses in the presence of the light while the TL group emitted a significantly lower 40% of their element responses in the light. The distribution of element responses for the TL group, for whom no food was received in TL, resembles that of animals that avoided shock in TL in the Schindler and Weiss (1982) study. This can be appreciated when Fig. 2 is compared to the left frame of Fig. 1. The stimulus–element test in Fig. 2, wherein TL+ and TL were generated solely with food-related contingencies, produced a selective-association interaction profile similar to those reported by Schindler and Weiss (1982) and Foree and LoLordo, where TL+was food related and TL was shock related. This demonstrated that the dynamics underlying selective associations might be better understood in terms of the equivalence of excitors and inhibitors of contrasted affective value – an explanation confirmed by Weiss et al. (1993b) who Selective Associations Weiss, Panlilio, & Schindler (1993a) % Element Responses 70 Tone 60 50 40 Light 30 FoodRelated TL+ FoodRelated TL− Selective Associations.

In training, see text, a food contingency maintained responding in TL in both groups. However, all food was received in TL by the TL+group while no food was received in TL by the TL group. When the underlying food reinforcement contingency created a TL+(preferred), responding was primarily controlled by the light component of the TL compound. In contrast, when a TL (nonpreferred) was created the tone component gained control [Adapted from Fig. 3 of Weiss et al. (1993a)] reported selective associations when responding in both TL+and TL were maintained by shock-related contingencies. The relative hedonic value of TL (as measured by component preference or observing behavior) appear to be a determinant of stimulus control in these situations. This should encourage us to look for biological constraints (influences) on learning at a higher level of processing than heretofore since selective associations appear to be a product of a conditioned psychological hedonic state. If this turns out to be the case, it could mean that the variables involved in fundamental psychological processes such as choice behavior in general, conditioned preference, and appetitive–aversive interactions might also contribute to selective associations. This strongly suggests that selective associations be viewed from the broader perspective of conditioned hedonic states. That selective associations can be S 2987 produced by manipulating contingencies involving solely food or solely shock should increase our appreciation of the power of contingencies themselves in fostering comparisons between schedule components that influence stimulus selectivity. Food and shock appear to have been the most straightforward and direct ways of producing these positive and negative, respectively, hedonic states in early selective association research. That seemed to divert attention from the fundamental hedonic processes responsible for the phenomenon in traditional conditioning and learning situations. As the many cross-references listed below reveal, this integrative connection relates selective associations to fundamental processes in conditioning and learning.

Selective attention is defined as observing specific models rather than any group members. Theoretical Background Efficient ▶ social learning plays a major role in human life as it provides the basis for traditions and culture (Plotkin 2007). Consequently, studying the roots of culture in other animals has been a key research topic for decades (Whiten 2009). Laboratory experiments demonstrated that a variety of vertebrate species might be able to learn socially, and many field studies documented either the spread of innovations are important differences between populations that seem to be based on traditions. However, experiments are needed to test rules for social learning. Theoretical studies on social learning rules suggest that individuals should be selective when deciding both when to learn socially and who to choose as a model (Boyd and Richerson 1985). The hypothesis that individuals should copy group members that are currently successful at a given task has repeatedly received experimental support (Kendal et al. 2009). In contrast to a scenario where individuals constantly monitor each other and compare relative gains, the “social model hypothesis,” also known as BIOL (bonding and identification-based observational learning), predicts that primates living in structured social groups are most likely to learn from social models that have general qualities such as high relatedness (the mother), knowledge, high age, and/or high rank (de Waal 2001). In contrast, actions of young or less familiar members may be largely ignored, even in situations where such individuals have found the best solution. Important Scientific Research and Open Questions The BIOL hypothesis has been tested with a social learning experiment on six wild vervet monkey groups, where models were either a dominant female or a dominant male. In this species, females remain in their group of birth, while males migrate once sexually mature. Thus, social links to females should be stronger and more important than social links to males, genetic relatedness to females should be higher than to males, and females should on average be more knowledgeable about food sources in the territory. Together, these factors lead to the prediction that individuals should be more likely to copy females than males. In the experiment, “artificial fruit” boxes that had doors on opposite, differently colored ends for access to food were presented to the monkeys. One option was blocked during the demonstration phase, creating consistent demonstrations of one possible solution by a monopolizing dominant individual. Following 25 correct demonstrations, all other group members were exposed to the box with both doors functional. We observed a significantly higher participation rate (“stimulus enhancement,” def: Hoppitt and Laland 2008) in groups with female models compared to groups with male models, and only in the former we found a significant preference of subjects to manipulate the same-door manipulation as the model (“local enhancement,” def: Hoppitt and Laland 2008). These findings implied a different copying rate of group members, depending on the identity of the model. Analyses of the context of the demonstrations revealed Selective Learning that the bias is not due to lack of tolerance or aggressiveness of male models. However, when observing gazes toward the models, significant results were found providing evidences for selective attention toward female models. These results demonstrated the favored role of dominant females as a source for “directed” social learning in a species with female philopatry. Females should often be better than immigrants as sources for social learning, at least in the context of foraging. Based on our findings, we hypothesize that in species in which members of one sex form the core of stable groups, the migration of individuals of the other sex leads to proper exchange of genetic adaptations but much less to the exchange of socially acquired adaptive information. Our findings imply that migration does not necessarily lead to an exchange of socially acquired information within populations, potentially causing highly localized traditions. These results suggest the importance of the philopatric sex for the transmission of knowledge. A comparison between species with different migration patterns would be very instructive. The study described above did not address other potential key variables like rank, age, or relatedness. Furthermore, one should test social learning patterns in contexts other than feeding, like social behaviors or communication. Such tests would allow answering the question whether philopatry matters across contexts or whether role models are chosen according to their abilities in each specific domain. Combined analyses would yield a clearer picture concerning the scale of traditions. Typically, researchers have assumed that differences mainly occur between populations, but the results on vervet monkeys imply the prevalence of distinctive traditions within populations.

Selective Learning GERRI HANTEN Cognitive Neuroscience Laboratory, Dept. of Physical Medicine and Rehabilitation, Baylor College of Medicine, Houston, TX, USA Synonyms Selective remembering; Strategic learning; Strategic memory; Value-directed memory Definition Consider this situation: you are on the way to the grocery store, but you have forgotten your list. The complete list of 18 items included butter, carrots, celery, cheese, chocolate, eggs, flour, garlic, juice, lemons, lettuce, milk, peppers, potatoes, salt, soup, walnuts, and yogurt. Some of these are everyday items that need to be restocked soon (low immediate value), and others are items you need to bake a cake for a friend’s birthday this evening (high immediate value). Which ones will you remember, how, and why? The answers to these questions are explored in the study of selective learning. Thus, selective learning is the value-based strategic memory for a subset of items most important to achieving a current goal. Theoretical Background Selective learning, the ability to select items from among other items to learn based on value, requires the appropriate allocation of cognitive resources, allowing for S 2990 S Selective Learning preferential focusing on those items of greater value while taking into consideration the limitations of memory span. Although the degree to which memorial processes can be wilfully controlled has been studied in adults since the early 1970s, these studies generally have investigated the ability of individuals to ignore irrelevant (or no-value) items in favor of relevant items, as in the directed forgetting paradigms developed by Robert Bjork and his colleagues, and other studies of the effects of incentive on memory. Selective learning paradigms address the bias to remember important items in preference to items of lesser importance when all items have value. Typically two measures are taken: total words recalled, for an estimation of memory span, and a selective efficiency score. The selective efficiency score is calculated by the formula (actual score – chance score)/(ideal score – chance score) where actual score = sum of the point values of items recalled; chance score = the score predicted in the absence of selection given the number of items recalled (i.e., if half the words recalled were high value and the other half were low value); ideal score = the maximum score that could be achieved given the number of items recalled. Thus, the index of selective efficiency is based on the maximum score possible for an individual given his/her total words recalled. The range of the index extends from 1 to 1, with a score of 0 indicating chance performance (that is, equal numbers of high and low items). Selective learning is a skill that is highly applicable to everyday memory function in both adults and children. Given the limits of human memory, the ability to respond appropriately to value with regard to what one recalls is highly adaptive. Evidence of an innate ability to select information for learning based upon the inherent importance or relevance to personal objectives is reflected in behavioral observations of conditioned responses in animals and humans, which suggests the ability to select personally relevant information for learning may be instinctively driven. Thus, it may be that humans are naturally inclined toward strategic learning of important information. Some key elements involved in selective learning are: 1. Memory span, typically immediate memory for word lists although studies on selective learning of items within connected text have been done. The relation of selective efficiency to memory span is not straightforward, and several studies have reported dissociations between memory span and selective efficiency in normal and clinical populations. (Castel et al. 2007; Hanten et al. 2007). 2. Inhibitory processing, or the ability to suppress retrieval of less relevant items. Studies examining the ability to select information for learning based upon extrinsically assigned value (i.e., holds little to no personal significance) have emphasized the role of controlled cognitive processes (Hanten et al. 2002). A number of studies show that cognitive control develops throughout childhood and into early adulthood and is closely tied to frontal lobe development. The frontal lobes show a protracted development period that extends from childhood into late adolescence or early adulthood. Hence, if cognitive control is a primary factor, selective learning proficiency may rely on frontal lobe development. 3. Incentive, or response to reward. Although motivation is a very likely contributor to selective efficiency, under some circumstances it fails. For example, when the value (including monetary reward) of the items is designated after presentation of the items, selective efficiency is greatly diminished, if not eliminated altogether (Hanten et al. 2002), thus suggesting some limits of cognitive control on incentive. 4. Metacognition. Because instructions for selective learning tasks typically emphasize that the goal is to earn a high number of points, but do not provide explicit directions for achieving that goal, selfawareness of one’s memorial limitations and the ability to implement an effective strategy is an advantage. If a person can remember all items, low and high value, he or she need not select to remember in order to make a high score. However, a person who is aware that there are more items than can be remembered may devise a strategy to remember only high value items, thus allowing a high degree of selectivity. Important Scientific Research and Open Questions The field of selective learning is understudied. A few studies relating to this topic (under various rubrics of Selective Learning selective learning, strategic learning, selective remembering, and value-directed learning or memory) have been largely limited to clinical or developmental studies, although there are a few studies exploring the mechanisms of selective learning. In non-clinical populations, studies have been performed that address selective learning in children and in adults. Castel and colleagues (e.g., Castel et al. 2007) investigated the differences in selective learning in older and younger adults, found both groups (older and younger adults) were equally good at recalling the range of points assigned to high-value words, but younger adults outperformed older adults when recalling specific values. Both groups exhibited poorer recall of negative value information. This was interpreted to suggest that older adults rely more on gist-based operations, whereas younger adults remember specific numeric value information. In another study, Castel and his colleagues found that older adults recalled fewer words overall than younger adults, but showed greater efficiency in recalling high value words. At the other end of the developmental spectrum, Hanten et al. (2007) explored selective learning using auditory word lists in typically developing children, and found memory span to have a different developmental trajectory than selective efficiency, with the two measures not significantly related to one another. In a different study of selective learning in children for visually presented stimuli, Hanten and her colleagues reported that the mode of presentation was an important factor: there is an advantage for the simultaneous presentation of all words in one list rather than presenting each word singly and sequentially, and an advantage for selecting on the basis of physical characteristics of the stimuli (type of print used for the words) rather than the semantic characteristics of the stimulus set (i.e., natural category membership). Efficiency of some types of selective learning appears to depend on the relative incentive associated with stimulus items, and to increase with age. Studies of the trade-off between the ability to select for specific items and the total number of words recalled indicate that the cost (in terms of the number of words recalled) associated with more efficient selection appears to decrease with age (Miller et al. 1991). Selective learning paradigms have been found useful in examining areas of cognitive impairment and relative preservation in clinical populations. In a number of S studies, Hanten and colleagues have demonstrated that children with traumatic brain injury are impaired in selective learning efficiency for word lists relative to typically developing children in verbal selective learning in both auditory and visual modalities, and for connected text, with total word recall relatively preserved (Hanten et al. 2002, 2004). Castel and colleagues have revealed that children with ADHD, especially Combined Type ADHD, have shown much the same pattern, with no between-group differences between children with ADHD and controls on total word recall, but deficits in selective efficiency in children ADHD (Castel et al. 2011). Castel and colleagues have also studied selective learning in patients with Alzheimer’s Disease, who were found to be impaired in selective efficiency. Other clinical populations with reported deficits in selective learning are children with spina bifida, who demonstrate impaired word recall relative to typically developing children, but relatively preserved selective efficiency. However, children with spina bifida did report the use of an inefficient strategy to remember all the words as compared to the control group, who indicated they tried to remember the high value words. Selective learning is a skill important to everyday function, and especially salient in children. The field of study is in its infancy and would benefit from more studies of the perceptual and conceptual parameters that affect selective efficiency, the nature of strategy employed, development of aspects of selective learning, as well as studies of cognition in clinical populations. Further, to date, there is a paucity (or complete absence) of studies illuminating brain-behavior relationships in selective learning, or in the role of selective learning in social-cognitive domains.

Self Processes and Learning ▶ Identity and Learning Self-Adaptation of Cultural Learning Parameters DARA CURRAN Computer Science Department, Cork Constraint Computation Centre (4C), University College Cork, Cork, Ireland Synonyms Evolutionary computation Definition Self-adaptation of parameters is a technique employed by evolutionary computation researchers to evolve populations to solve a particular problem while, at the same time, adjusting its own parameter set to improve performance and fitness. Self-adaptation is related to coevolution in the sense that the values for chosen parameters are evolved at the same time as the population itself. The adaptation of parameters for cultural learning is focused on evolving good parameter values for the purposes of producing effective cultural learning within a population. Theoretical Background Some research has been performed on the selfadaptation of parameters employed in evolutionary computation. Angeline (1995) divided such adaptation into three groups: population level, individual level, and component level. Population-level adaptation dynamically adjusts a parameter that is subsequently used globally across the population, such as a global crossover value Self-Determination and Learning S (Spears 1995). Individual level-adaptation reduces the impact of a parameter to an individual level, such as adapting crossover points (Rosca 1994). Componentlevel adaptation dynamically changes the way in which individual components of an individual will be altered independent of one another (Back and Schwefel 1993). Researchers have applied self-adaptive parameters at varying levels to evolutionary programming (Fogel et al. 1991) and to genetic algorithms (Back 1992; Hinterding 1995; Smith and Fogarty 1996).

Important Scientific Research and Open Questions ▶ Meta-learning The model proposed by Curran et al. shows that the addition of cultural learning to evolutionary learning has beneficial effects in terms of fitness, as seen in previous work. Furthermore, results obtained from the examination of the self-adaptive parameters illustrate the relative quality of teachers (and, therefore, the impact of cultural learning) at different stages in the experiment. The fact that the values for these parameters changes significantly throughout the experiment shows the usefulness of self-adaptive cultural parameters for both performance and analysis of cultural learning. 2993 Self-Adaptive Systems Self-Awareness ▶ Self-Reflecting Methods of Learning Research Self-Centered Learning ▶ Narcissistic Learning Cross-References ▶ Computational Models of Human Learning ▶ Cultural Learning ▶ Metalearning ▶ Population Learning Self-Control ▶ Self-regulation and Motivation Strategies References Angeline, P.

WILLEMS, DORIS LEWALTER TUM School of Education, Fachgebiet für Gymnasialpädagogik, Technical University of Munich, Munich, Germany Synonyms Autonomy; Self-direction; Self-regulation Definition The concept of self-determination is used in various theories of learning and instruction. Over the past S 2994 S Self-Determination and Learning decades, Self-Determination Theory (SDT) (Ryan and Deci 2008) has evolved as an influential framework, especially in education and learning. According to SDT, students who feel that their learning is self-determined/autonomous experience their studying as a selfchosen, volitional act that reflects their individual goals and values. Experiencing autonomy/self-determination in learning involves a sense of unpressured willingness. It is defined as full and nonconflictive endorsement to engage and proceed in learning. In that sense, autonomy concerns the extent to which students authentically and genuinely concur with the (external) forces underlying specific learning situations. Self-determination/autonomy encompasses ideas such as self-direction, self-governance, self-regulation, coherence with the self, and the experience of freedom and volition. It excludes concepts such as individualism, independence, power, dominance, or selfishness (Assor and Kaplan 2001). Theoretical Background A key concept in theories about processes of teaching and learning is motivation. Students often struggle to mobilize their efforts, to find energy to start and persist at learning tasks, and to direct their endeavors toward the achievement of learning goals. Complementarily, teachers are concerned with fostering their students’ learning processes and seek ways to facilitate their motivation. This challenge is particularly evident as academic learning is often driven by external factors such as grades, evaluations, and imposed learning goals. Schools, as one predominantly outcome-oriented context of formal learning, have always imposed structures and controls. But with the strong emphasis on educational accountability and high-stakes testing, the intensity and consequences of such controls have recently increased (Reeve 2002; Ryan and Deci 2009). SDT represents a framework for analyzing human motivation and personality. At its core lies the investigation of the interplay between extrinsic forces influencing human behavior and intrinsic motives and needs inherent in human nature. SDT formulates a meta-theory for framing studies of motivational development in different contexts, including the fields of teaching and learning. The theory follows an integrative organismic and dialectical approach (Ryan and Deci 2008): SDT emanates from the assumption that humans are active organisms, with evolved tendencies toward learning, mastering challenges, and integrating new experiences into a coherent sense of self. Additionally, SDT postulates that these prevalent natural developmental tendencies do not operate automatically. Instead, they require external supports. Here, SDT focuses on the analysis of contextual factors that either support or thwart the natural tendencies toward active engagement and learning. Regarding institutionalized academic learning processes, the dialectic between students as active organisms and their social context is the basis for SDT’s predictions about the students’ behavior, experience, motivation, and development in learning (Reeve 2002). Based on this framework, SDT comprises four mini-theories, each of which was developed to explain different motivationally based phenomena. For academic learning, the Cognitive Evaluation Theory (CET) and the Organismic Integration Theory (OIT) are vital to understanding the quality and outcomes of learning processes (Ryan and Deci 2008). At the center of CET lies the concept of intrinsic motivation which is understood as the prototype of self-determined regulation. Intrinsically motivated behaviors stem from the inherent satisfaction of the behaviors per se rather than from contingencies that are operationally separable from the activity itself (Ryan and Deci 2008). The aim of CET is to identify situational factors of learning environments that account for the variability in students’ intrinsic motivation. Here, the basic psychological needs for autonomy, competence, and relatedness are important. CET states that the more a learning environment facilitates the students’ basic needs, the more likely intrinsic motivation develops. This postulate is seen as universal across age, gender, culture, context, and background. The need for autonomy refers to being the origin and source of one’s own behavior. It is defined as feeling volitional and congruent with respect to what one does. Experiencing autonomy also means feeling selfgovernance concerning the initiation and direction of behaviors (Assor and Kaplan 2001). Historically, this need goes back to Richard de Charms’ concept of personal causation and is also related to Julian B. Rotter’s concept of an internal locus of control. The need for competence refers to the need to feel effective in the interaction with the social environment and to experience opportunities to exercise, expand, and express one’s capacities. It is derived from Robert White’s concept of effectance motivation. Finally, relatedness refers Self-Determination and Learning to the need to feel connected with others, to care for and to be cared for by others, and to have a sense of belongingness and respect within one’s own community (Ryan and Deci 2008). It is rooted in Abraham Maslow’s need of relatedness and David McClelland’s need for affiliation. Whereas modern theories of motivation (expectancy-value theories, social cognitive theories) treat motivation as unitary concept that typically varies in amount but not in kind, SDT focuses on different types of motivation, all of which differ in quality rather than quantity. Based on a classic dichotomy of intrinsic vs. extrinsic motivation, SDT further distinguishes between different kinds of extrinsic motivation. Instead of arguing that motivation per se is a key factor that influences learning, OIT asserts that the quality of motivation is decisive for the quality and outcomes of learning processes. OIT proposes a taxonomy of four different types of extrinsic motivation that vary in their degree of relative autonomy. The description of properties, determinants, consequences, and correlates of these types of extrinsic motivation are the major elements of OIT (Ryan and Deci 2009). Extrinsic motivation by definition comprises instrumentality: Externally motivated behavior aims toward outcomes which are separable from the behavior itself (Ryan and Deci 2008). Yet there are distinct forms of instrumentality. In OIT, these types of instrumentality are treated as underlying attitudes and goals that give rise to an action and regulate behavior. These types of regulation are eventually covered by the different qualities of extrinsic motivation. Following OIT’s argumentation, such subtypes of extrinsic motivation are arranged along a continuum of relative selfdetermination reflecting a process of internalization. This process is defined as a sequence of assimilating non-intrinsically motivated behaviors and values from the social environment into one’s own value and regulatory system: The more internalized the extrinsic motivation, the more autonomous the person will be and the more a certain regulation becomes part of the individual self. In line with findings from CET, OIT investigates the factors that conduce toward people either, resisting, partially adopting, or deeply internalizing values and goals. Much like intrinsic motivation, internalization is expected to occur spontaneously within certain learning environments: When students feel socially accepted and related to significant others, they are inclined to S 2995 internalize the values of those around them. When the support for the personal need for relatedness is further combined with supports for autonomy and competence, the process of internalization goes beyond mere value-assimilation and finally leads to a process of integration. Here, students more fully transform and incorporate the external regulation into their own regulatory system (Ryan and Deci 2009). The different types of extrinsic motivation are defined as follows (Ryan and Deci 2008): 1. External regulation: This form of extrinsic motivation is the least autonomous one. It entails being motivated to obtain rewards or avoid punishments. Behaviors based on external regulations are continued only as long as external demands are maintained. 2. Introjected regulation: Behaviors based on this type of motivation involve an external regulation that has been internalized but not fully accepted as one’s own. Introjected-based behaviors are performed in order to avoid guilt and shame, or conversely, to gain approval. Students, for example, aim at behaving like teachers, peers, parents, or society, expect them to act. 3. Identified regulation: This motivational quality is even more self-determined. It involves a conscious valuation of a behavioral goal or regulation. Behaviors based on identified regulations reflect the acceptance of the behavior as personally important. 4. Integrated regulation: This form of motivation provides the basis for the most autonomous extrinsic motivation. It represents the highest state in the process of transforming external regulation into true self-regulation. It results when the proceeding identification has been brought into congruence with the personal value system. On the motivational continuum, these types of extrinsic motivation are framed by the state of amotivation (as status of lacking an intention to act) on the one side and intrinsic motivation on the other. Regarding academic learning, this distinction accounts for the fact that most of the tasks worked on in formal learning contexts are not intrinsically motivated, but are – to varying degrees – externally driven. Furthermore, the continuum explains that not all forms of extrinsic motivation represent impoverished motivational states. Some forms even cover active and agentic S 2996 S Self-Determination and Learning states. As educators cannot always rely on intrinsic motivation to foster learning, understanding these different types of extrinsic motivation, their correlates, and the factors that foster each of them, is essential (Ryan and Deci 2009). Important Scientific Research and Open Questions Early work within SDTexamined whether offering people extrinsic rewards for doing intrinsically motivated activities affected their level of intrinsic motivation. Multiple findings primarily gained in laboratory experiments illustrated that tangible rewards diminish intrinsic motivation whereas positive, performance-relevant feedback maintains or enhances intrinsic motivation. To explain these mechanisms, SDT draws upon the functional character of the basic needs: When using rewards to prompt activities, people lose their sense of autonomy and therefore intrinsic motivation decreases. In contrast, when people experience an absence of external pressure, they experience self-determination which increases their intrinsic motivation. Similarly, effectance promoting feedback and optimal challenges help maintaining feelings of competence and thereby enhance intrinsic motivation. Negative feedback, especially when given in a controlling manner, or excessive demands undermine the experience of competence and decrease intrinsic motivation. These interpretations were confirmed by further studies: External events such as punishments, deadlines, imposed goals, pressure toward performance, competition, and evaluations undermine intrinsic motivation in learners because they thwart their needs for autonomy and competence (Ryan and Deci 2008). These findings were later transferred to the analyses of different forms of extrinsic motivation: Field studies conducted in educational settings supported two major conclusions: Autonomously motivated students thrive in educational settings and students benefit when teachers support their autonomy (Reeve 2002). Such educational benefits refer to both cognitive and affective components of learning: Selfdetermined motivation, for example, involves higher academic achievements, greater conceptual understanding and flexibility in thinking, higher amounts of active information processing, higher beliefs of competence, efficacy, and control, higher rates of retention, and higher senses of well-being and more positive emotionality. Autonomous forms of motivation are also empirically associated with greater engagement, less dropping out, more enjoyment, and better coping styles (Ryan and Deci 2009). These findings led to the analysis of autonomy-supportive teacher behaviors. Such behaviors are, for example, fostering understanding and interest, providing meaningful rationales, allowing criticism and encouraging independent thinking, and providing meaningful and true choices (Assor and Kaplan 2001). Based on these results, more recent studies heighten the ambivalent impact of choices on autonomy and self-determined motivation (Patall et al. 2008). Research shows that autonomy support can be manifested in diverse ways. One proposition is to distinguish between organizational, procedural, and cognitive autonomy (Stefanou et al. 2004). How far such different qualities of autonomy support also result in different forms of motivation is a mainly unresolved problem. Although research in SDT has a long and influential tradition in the field of learning and instruction, several questions are still unsolved. These open questions, for example, concern developmental and differential aspects of autonomous motivation: Whereas research has mainly focused on the effects of immediate contextual conditions that either support or thwart the basic needs, studies approaching the idea that basic need support also stems from individuals’ inner resources which potentially support ongoing feelings of autonomy and competence are at their infancies. How far contextual aspects and individual characteristics are intertwined in specific learning situations and how both factors function in relation to each other and in dependence to further constructs is a relevant question to answer. For future research, it is further important to understand how motivation emanating from the experiences in specific learning situations develops into a stabilized motivation that can be maintained across different learning situations.

Self-directed learning is a concept that came out of the humanistic tradition of adult education in the second half of the twentieth century. One of the first researchers on the topic, the Canadian scholar Allen Tough, viewed self-directed learning largely as an expression of human personal agency. Self-Determined Motivation ▶ Understanding Intrinsic and Extrinsic Motivation: Age Differences and Meaningful Correlates " 2997 Man [sic], according to this view, can be active, energetic, free, and aware. He often chooses his goals, direction, and behavior; he is not always pushed and pulled by his environment and by unconscious inner forces. (Tough 1979, p. 45) Theoretical Background SDL as Process Interestingly, Tough’s concept of SDL adhered more or less stringently to a linear process of learning that is similar to other types of programmed learning. For example, he described the self-directed learning project’s “stages” as being, 1. Decide on a learning goal 2. Determine a learning sequence and a learning schedule 3. Secure the physical and financial resources to pursue the learning project 4. Select a suitable place to learn Self-Directed Learning ▶ Independent Learning ▶ Scaffolding Discovery Learning Spaces ▶ Self-organized Learning 5. Select resources and materials 6. Find appropriate resource persons 7. Resolve motivation issues 8. Overcome learning difficulties 9. Minimize self-doubt Self-directed Learning and Learner Autonomy PAUL BOUCHARD Department of Education Educational Studies and Adult Education, Concordia University, Montreal, QC, Canada Synonyms Self-guided learning 10. Set subsequent learning goals at the end of a learning sequence The framework proposed by Tough has been applied to a large number of studies during the 1970s and 1980s that assumed more or less implicitly that self-directed learning is a process that can be accurately described and analyzed over time as a sequential series of events. Today, there are a large number of selfdirected “how-to” methods to be found in the educational world, particularly in the area of workplace learning, that adhere to this philosophy. S 2998 S Self-directed Learning and Learner Autonomy SDL as Personality During that same period, Lucy Gulglielmino was working on a model of individuals’ propensity toward selfdirection in learning. She derived a multidimensional model of assessment that is synthesized in a self-report Likert-scale test, called Self-Directed Learning Readiness Scale (SDLRS). Over the years, the SDLRS has been used to establish correlations between readiness for selfdirection and numerous other variables. For instance, Sabbaghian (1979) established a positive correlation between SDL and self-perception. Torrance and Mourad (1978) found that self-directed learners have a marked propensity for “right-hemisphere” tasks, such as creativity, analogy, and problem solving. Overall, according to Guglielmino’s view, not all persons exhibit the same predisposition for self-direction in learning, just as they differ in other psychological abilities such as creativity, problem-resolution, mathematical reasoning, etc. There was some debate over the validity of the SDLRS, mostly on the grounds that it tends to measure a propensity toward learning in general, rather than for self-directed learning in particular. Field (1989) and Bonham (1991) objected to the vagueness of the concept, self-direction, in Guglielmino’s work. Nevertheless, researchers in adult education are still using the SDLRS today, and the notion of self-direction as a personality trait is still very much alive. Situating their work in the light of Kurt Lewin’s “field theory,” Mocker and Spear introduced the notion of the “organizing circumstance” to shed some doubt on the linear character that theorists would impose on all types of learning, and especially self-directed learning. In particular, they contend that the task of planning a learning sequence is a rather specialized task for which a learner in the natural setting is not likely to be prepared. In the end, they conclude that it is not reasonable to assume that self-directed learning projects can be planned in a similar way as formal learning projects. This realization is being made today by proponents of self-managed learning networks or connected “personal learning environments.” Dimensions of Learner Autonomy Certainly the most complete discussion of selfdirection in learning is to be found in Candy’s classic work published in 1991. In that book, Candy (p. 101) introduces the dual nature of learner autonomy, both as an expression of self-determination (the personal disposition to pursue learning) and of selfmanagement (the ability to exert control over one’s learning process). In order for self-directed learning to occur, both conditions of learner autonomy must be present. Candy defines the pursuit of a SDL project as, " Being able to pursue a learning goal with equal vigour and determination without being adversely affected by external factors including the increase or decrease of rewards for pursuing or attaining the goal (. . .) " Conceiving of goals, policies and plans independently of pressures to do so, or not do so. (Candy 1991, p. 181) SDL as Environment George Spear and Donald Mocker (1984) introduced the notion of SDL as an environmentally determined phenomenon. While Tough and Guglielmino contended that self-directed learners have the will and capacity for carrying out personal learning projects, Spear and Mocker pointed out that this was often not the case at all. Their research revealed that learning was determined by the learners’ surrounding circumstances much more than by their “determination” or their “inner predisposition.” Indeed, respondents to Spear and Mocker’s research stated that they had not planned any specific tasks or sequence in their learning. " Self-directed learners, rather than pre-planning their learning projects, tend to select a course from limited alternatives which occur fortuitously in their environment. (Spear and Mocker 1984, p. 4) And further: " Being aware of alternative choices, both as to learning strategies and to interpretations or value positions being expressed, and making reasoned choices about the route to follow in accordance with personally significant ideas and purposes. (Candy 1991, p. 261) The first quote refers the learners achieving some kind of freedom from the interfering forces of teachers and institutions, while the second alludes to learners’ actual ability to structure and conduct their own learning. These are the first two “dimensions” of learner autonomy. Self-directed Learning and Learner Autonomy The Conative Dimension The first expression of learner autonomy resides in the motivational-intentional forces that drive the learner to apply some determination (or “vigor”) to the act of learning. This area embodies the conative functions of learning, which are at the foundation of learner initiative, motivation, and personal involvement. Most often, adult learners harbor life-goals that are related, but distinct from the actual learning goals (e.g., career advancement, good parenting, or better health), as part of the conative baggage they carry. Other possible drives include the pleasure one derives from the act of learning in itself, and the satisfaction obtained from becoming part of a particular culture of knowledge (Houle 1961). Learner autonomy entails the possibility for individuals to make choices (or exercise control), beginning of course with the choice of whether to learn anything at all in the first place (Candy 1991; Long 1993). This can be construed as the opposite of some forms of “other-directed” learning such as mandatory schooling, or of some instances of workplace learning, where people have no choice about whether to learn, or what to learn. So, the first area where learners may exercise control over their learning lies in their option to initiate and pursue learning, or to choose to do something else instead. Interestingly, this means that two learners sitting side by side in the same classroom can be said to exercise contrastingly different levels of learner autonomy: the first student having chosen to be there, while the other has not. The Algorithmic Dimension The second set of elements that define learner autonomy involve control over the aspects of learning usually taken over by a teacher or by a managed learning environment (MLE). They include defining learning goals, deciding on a learning sequence, choosing a workable sequencing and pacing of learning activities, and selecting learning resources (Hrimech and Bouchard 1998). These elements can be grouped under the heading of the algorithmic dimension of learner autonomy. In traditional learning environments, most of the algorithms are the responsibility of a teacher or a teaching institution. Learning goals, student workload, and methods of evaluation are usually stipulated at the outset and little participation in their formulation is expected from the learner. But some of the S 2999 “teaching tasks” normally reserved for the instructor can also be devolved to the learner, on top of the expected “learning tasks.” In this sense, we can say that autonomy is directly related to the number and magnitude of the “teaching tasks” that are appropriated by the learner (Tough 1965). Important Scientific Research and Open Questions Learner Autonomy in Context The first two dimensions of learning that allow for the possible exercise of learner agency, or autonomy, are the conative (psychological) and the algorithmic (procedural) dimensions. However, these do not account for the considerable weight of contextual forces that inevitably influence the learning process. Let us consider for example the fact that learning can occur within or without a formal learning institution, knowledge can be pursued alone, in small or large groups, using prescribed texts or self-researched online resources, etc. In order to take into consideration the various contexts of learning, we have proposed two other dimensions of learner autonomy (Bouchard 2009). The Semiotic Dimension Just a few years ago the resources for learning were limited to interacting with printed text, or face-toface with other people. Today, the means of communicating information are very diversified and include print, nonprint, multimedia, hypertext, internet web pages, RSS feeds, and social networking. While these may or may not affect the actual goals or outcomes of learning (the algorithms), they will alter significantly the learning process. Furthermore, individual learners vary in their preferences for different environments (British Library and JISC 2008). For instance, hypertext can be selected as a means of aggregating information or shunned as a mish-mash of poorly organized data. Similarly, poring over texts in a library offers a very different experience from lively participation in a blog post. Each medium and its ultimate organizational form carries its own set of pragmatics that will largely determine the quality of the learning experience. These examples among others illustrate the importance for learners of making choices within the semiotic dimension of learner autonomy. S 3000 S Self-directed Learning and Learner Autonomy The Economic Dimension The traditional access to knowledge has been through academically sanctioned programs in schools and colleges. The alternative was self-directed learning – to pursue learning on one’s own or with the help of informal mentors. It can be argued that both processes lead to similar results in terms of learning achievement. The main difference lies in the institution’s delivery of an officially sanctioned, recognized accreditation. While there may be little consequence, pedagogically speaking, of choosing one alternative over the other, the outcome is of some importance economically when a learner enters the job market. In today’s exploding “knowledge economy,” the types of choices that have economic impact are no longer binary (formal vs nonformal) but are multiplied exponentially. The value of learning is no longer the simple calculation of the cost of schooling against the benefits of the degree conferred. The value of learning must be assessed in light of numerous factors. For example, the “perceived” value conferred by academic credentials can be matched or surpassed by the “actual” value of knowledge in the marketplace. The cost of acquiring credentials also varies from one institution to the next, especially in their online offerings. In short, learners in today’s complex environment typically must exercise choices in the economic dimension of learner autonomy. Conclusions Self-directed learning has been defined as a process, a personality construct, and an environmentally determined phenomenon. In the end, any tangible occurrence of self-directed learning undoubtedly involves the interaction of all three aspects, in that it will entail (1) the application of some actions or procedures, (2) by a person who is not psychologically averse to the experience, (3) in an environment, which at the very least does not preclude the emergence of selfdirected learning. Learner autonomy is a multidimensional concept that involves the exercise of learner-control in four areas. The conative dimension represents the inner motives and self-determination of the learner; the algorithmic dimension refers to the actual procedures involved in the learning process; the semiotic dimension includes the symbolic and pragmatic features of the learning environment; finally, the economic dimension allows for the estimation of the value of learning in its particular context. In the course of pursuing their self-directed project, learners will typically exercise some degree of control in each of the dimensions of learner autonomy.

USHER Educational, School, and Counseling Psychology, University of Kentucky, Lexington, KY, USA Synonyms Academic self-efficacy; Motivation to learn; Self-regulatory self-efficacy; Study skills self-efficacy Definition Self-efficacy for self-regulated learning refers to the beliefs individuals hold in their capabilities to think and behave in ways that are systematically oriented toward or associated with their learning goals. Students with a robust sense of efficacy in their self-regulatory capabilities believe they can manage their time effectively, organize their work, minimize distractions, set goals for themselves, monitor their comprehension, ask for help when necessary, and maintain an effective work environment. Theoretical Background In 1986, psychologist Albert Bandura advanced a theory of human functioning that emphasized the role of cognitive, vicarious, self-regulatory, and selfreflective processes in human adaptation and change. This view highlights the primary role of humans as agentic forces in their own development and stands in contrast to previous psychological theories, which viewed people as reactive organisms primarily shaped by their environments or driven by hidden inner impulses. Social cognitive theorists explain human S functioning as the result of the interaction between personal (i.e., cognitive, affective, and biological), behavioral, and social/environmental factors. These three factors influence one another in a process of triadic reciprocality. For this reason, humans, through their own cognition and behaviors, are thought to play a primary role in determining the course their lives will take. Social cognitive researchers have noted the importance of human agency in the learning process. To be successful, learners must monitor their own behavior, manage changing environmental conditions, and regulate their own cognition so as to select, initiate, and engage appropriate strategies throughout the learning process. Self-regulated learning involves metacognitive awareness that leads to goal-directed activities such as attending to instruction, selecting relevant information, connecting new learning to prior knowledge, motivating one’s self, and establishing productive work routines and environments (Schunk and Zimmerman 2003). Zimmerman (2000) described a three-phase, cyclical model of self-regulation by which individuals engage in (a) a forethought phase that sets the stage for action, (b) a performance phase in which learning tasks take place, and (c) a self-reflection phase during which learners reflect on their strategy use and prior performance. The decision to engage in self-regulatory learning strategies depends in part on one’s beliefs in one’s capability to employ the strategies required to achieve desired learning outcomes, or one’s self-efficacy for self-regulated learning. Learners must not only know what strategies are needed to achieve desired learning outcomes, they must also possess a belief that they are capable of employing such strategies. For example, a writer might know that outlining, drafting, incubation, and revision are all important steps to producing a good manuscript, but unless she feels confident that she is capable of accomplishing these steps, she is unlikely to initiate them. During the performance phase, students who believe they are capable of accomplishing given learning tasks make better use of cognitive strategies and persist longer than do those who harbor self-doubts. After they have performed, students interpret the results of their actions, the social cues they receive from others, and their own physiological and emotional states to revise their efficacy judgments, which 3001 S 3002 S Self-Efficacy for Self-Regulated Learning are then used to initiate a new self-regulatory cycle. Throughout this cyclical process, learners set goals, plan their strategies, observe and learn from models, assess their self-efficacy, evaluate their goal progress, and alter their task strategies as needed. Developing and maintaining a sense of self-efficacy helps to motivate students and to promote their self-regulated learning (Zimmerman and Cleary 2009). By assessing learners’ self-efficacy for self-regulated learning, teachers will know with greater certainty whether learners will in fact regulate their learning appropriately. Important Scientific Research and Open Questions A key determinant of whether learners employ selfregulatory strategies rests in the beliefs they hold about their capabilities to do so (see Zimmerman and Cleary 2006). Self-regulatory efficacy beliefs influence a number of outcomes. First, students who possess a robust belief in their self-regulatory capabilities engage successful self-regulatory skills and strategies across academic domains. Second, students’ self-efficacy for self-regulated learning has been shown to be related to key motivation variables, such as academic self-efficacy, self-concept, perceived value of school, and achievement goal orientation (i.e., positive relationship with mastery goals and negative relationship with performance-avoidance goals). Third, self-regulatory selfefficacy is related to students’ academic performance in domains such as writing, science, mathematics problem-solving, and general academics. Self-regulatory efficacy beliefs are also predictive of students’ school achievement such as course grades. Self-efficacy for self-regulated learning is inversely related to some affective variables. For example, students who report higher academic and subject-specific anxiety report less confidence in their self-regulatory capabilities. Students’ self-efficacy for self-regulated learning has been found to vary among different groups of students. Girls typically report higher levels of self-efficacy for self-regulated learning than do boys (Pajares 2002). Some scholars have reported that students’ confidence in their self-regulatory capabilities declines as they progress through school, even though older students use more self-regulatory strategies (Usher and Pajares 2008). In lower school grades, many academic tasks and activities are structured, guided, and closely monitored so as to instruct and instill the self-regulatory habits that will serve youngsters for years ahead. As students approach secondary school, they face more demanding academic work that is no longer chaperoned by external aids. Older students are often expected to regulate their academic work and study habits on their own, and many lose confidence when their self-regulatory skills are insufficient for new task demands. Successful learners are able to self-regulate across the situational demands they face. As Bandura (2006) contended, “The issue is not whether one can do the activities occasionally, but whether one has the efficacy to get oneself to do them regularly in the face of different types of dissuading conditions” (p. 311). Because self-efficacy refers to a task-specific judgment of what one can do, it is likely that self-efficacy for self-regulated learning will prove maximally predictive of academic outcomes when it is measured in a manner that is specific to the academic task at hand. For example, beliefs in one’s capability to minimize distractions while reading complex information may be related to behavioral or motivational outcomes in the domain of reading but not in the domain of mathematics. Researchers must be attentive to the local contexts in which self-efficacy is being assessed. One context in which self-efficacy for self-regulation might play an increasingly important role is in digital learning environments. When learning activities require the use of digital learning devices, one’s beliefs that one can stay on track by reducing distractions and staying focused may become even more consequential. This area offers a promising avenue for future research.

Self-Esteem and Learning DORIS LEWALTER, ARIANE S. WILLEMS TUM School of Education, Fachgebiet Gymnasialpädagogik, Technical University Munich, Munich, Germany Synonyms Self-regard; Self-respect; Self-worth Definition Self-esteem describes a subjective way of experiencing one’s own self. It encompasses cognitive, emotional, and evaluative dimensions and generally describes how much value people assign to themselves. Self-esteem in this sense reflects a person’s overall appraisal of his or her own worthiness, competence, and personality. Theoretically, personal self-esteem applies to different levels of generalization: As individual trait variable, self-esteem is treated as a general or global psychological construct functioning across various life domains. On a more S 3003 specific and content-related level, it is specified as a multidimensional concept including four major areas: the intellectual, social, emotional, and physical aspect of self-esteem. These factors describe different dynamic parts of a person’s self-esteem as a state variable that operates within particular situations. Within each of these factors a distinction between several facets can be made. For example, the intellectual self-esteem of a person, which is activated in learning situations, is usually differentiated with regard to a specific subject matter or content domain. Although self-esteem is related to the concept of self-efficacy it differs from it. Self-efficacy in contrast to self-esteem implies a future time component and is conceptually restricted to subjective competence perceptions. Hence, self-efficacy in general relates to a person’s perception or belief of his or her future ability to reach a goal or produce a certain level of performance in a particular task within a specific situation. Theoretical Background The term self-esteem has a long history and is still used in various ways (Kernis 2006). In earlier theories selfesteem was conceptualized as a basic human need or motivation. For example, Abraham Maslow (1987) included two different forms of self-esteem in his hierarchy of needs, a lower and a higher form of selfesteem. He differentiates between both, the need to be respected by others and the need for self-respect or inner self-esteem. The former describes the need for recognition, attention, acceptance, and appreciation. The latter one involves ideas such as the individual need for strength, competence, self-confidence, and freedom. Maslow assumed that inner self-esteem is the higher form because it is both more personal and stable, as it particularly refers to the valuation of inner competencies. The need to be respected by others on the opposite side represents the lower form of selfesteem as it seems to be more fragile and dependent on the valuation of others. According to Maslow’s proposed hierarchy of needs, the fulfillment of the needs for love and belonging is a necessary precondition for perceiving self-esteem and confidence. The fulfillment of the need for self-esteem in turn is required for an individual’s personal growth and for obtaining self-actualization. Further conceptualizations define self-esteem in terms of a one-dimensional approach of worthiness (e.g., Morris Rosenberg). Other approaches define self-esteem as a direct S 3004 S Self-Esteem and Learning function of a person’s experienced competence and effective behavior in important life domains as well as a kind of personal response to the approval gained by significant others (e.g., Susan Harter). According to this definition self-esteem is based on success and achievement. In most of the current theories and research approaches, self-esteem includes a combination of both aspects; competence and worthiness (Mruk 2006). Selfesteem is defined according to these two interrelated aspects and entails a sense of personal efficacy and personal worth. It is conceptualized as the integrated sum of self-confidence and self-respect and describes the belief that one is competent to live and worthy of living (Mruk 2006). Self-esteem can be conceptualized either as an underlying dispositional tendency influencing a person’s behaviors and experiences across certain life domains – the so-called global or general self-esteem (trait self-esteem) – or as a more transitional psychological condition mainly operating within particular domains (state self-esteem). Both conceptualizations of self-esteem are substantially correlated with one another. Yet, the mutual relation between a global self-esteem and a more domain-specific self-esteem is discussed controversially (Kernis 2006): It is an open question whether domain-specific factors of selfesteem emerge from a differentiation of experiences related to the global self-esteem or whether the global self-esteem emerges by processes of generalization based on experiences affecting domain-specific components of self-esteem. Self-esteem in general refers to a person’s subjective belief about herself or himself. Baumeister et al. (2003) point out that such subjective beliefs do not necessarily correspond to a person’s real characteristics. Thus, high self-esteem may stem from an accurate and warrantable appreciation of a person’s own worthiness or his or her success and competencies in an important domain, but it can also be built on an inflated, unjustified sense of imagined superiority over others. Accordingly, low selfesteem can be either a realistic, well-founded understanding of one’s insufficiency as a person or a biased, even pathological sense of insecurity and inferiority. As a person’s subjective sense of self-esteem does not imply any definitional requirements of accuracy, it is rather perception than reality (Baumeister et al. 2003). Therefore, level and quality of self-esteem are two distinct characteristics although they are correlated. Regarding the quality of self-esteem, various differentiations are made like, for example, fragile vs. secure self-esteem, conscious vs. unconscious self-esteem, or implicit vs. explicit self-esteem (Kernis 2006). Furthermore, self-esteem is not only based on an absolute appraisal but rather on a social comparison. A person’s self-esteem stems from the assumed difference between him or her and the group of reference, for example, a school class. The effects of social comparisons on self-esteem are particularly strong for the intellectual part of a person’s self-esteem, which is activated in specific learning situations. As self-esteem stems from social comparisons which in turn are particularly important in learning situations in order to develop a realistic intellectual self-esteem, empirical research on the development and the impact of self-esteem is important. Important Scientific Research and Open Questions In modern Western cultures, global self-esteem has been regarded as a psychological attribute of major importance. It was assumed that high self-esteem will cause many positive outcomes and benefits, like, for example, academic achievement, interpersonal and vocational success, well-being, health, and happiness (Baumeister et al. 2003). The underlying belief was: the higher person’s selfesteem the better. As a consequence, self-esteem enhancing projects were conducted. Regarding learning and school performance there are plausible reasons for that assumption (Baumeister et al. 2003). Learners with high self-esteem presumably set higher aspirations, may be more willing to persist when confronted with difficult tasks, problems or initial failure, and may be more confident to tackle demanding tasks. Students with high self-esteem should have less feeling of self-doubt and incompetence when facing a challenging task than learners with low self-esteem. Consequently, students with high self-esteem should reach high academic achievements und successes. Yet, various research findings gained over the last two decades illustrate that this simplified conclusion is not adequate (Baumeister et al. 2003). The empirical evidence that self-esteem improves performance in academic settings is weaker than expected. Correlations are both unstable and only modest on average. These modest correlations between self-esteem and school Self-explanation, Feedback and the Development of Analogical Reasoning Skills performance do not indicate that high self-esteem leads to good academic performance. Students with high self-esteem outperform students with low self-esteem only to a small extent. Recent research even partly indicates that high self-esteem as well as inflating students’ self-esteem has no significant positive effect on grades (Baumeister et al. 2003). Additionally, correlations by nature do not carry any information about causality. Recent research approaches aiming at disentangling causal directions via complex path analyses indicated that there is no direct causal path from self-esteem to learning, academic achievement, or performance. Such findings lead to the assumption that self-esteem and academic achievement mutually influence each other and are probably both results of a set of third variables like for example, ability or family background. Scientific results indeed support the hypothesis that high selfesteem is partly the result of school performance. Therefore, self-esteem seems to be an effect rather than a reason of high performance. In addition, interventions designed to raise self-esteem may either fail to influence academic performance or actually undermine it, for example, by encouraging a sense of complacency (Baumeister et al. 2003). Major open questions concern the conceptualization of self-esteem, its measurement, and the explanations of the role of self-esteem for other variables like, for example, learning, academic achievement, and success. In current research theories, there is a noticeable lack of a widely accepted conceptualization of what self-esteem actually is (Kernis 2006). There is no agreement even on basic aspects of self-esteem across the multiple theories available. This lack of correspondence has important implications on research and application. One consequence is a variety of different instruments of measurements reflecting somewhat different constructs of self-esteem. This is the case for trait self-esteem as well as state selfesteem. This leads to an inconsistent body of research results which entails divergent appraisals of the role of self-esteem for variables such as learning processes, persistence, academic achievement, or success.

TOWSE, LINDEN J. BALL, CHARLIE N. LEWIS Department of Psychology, Lancaster University, Lancaster, UK Synonyms Justification; Think-aloud protocols; Verbalization Definition Self-explanation is a general term used for verbalizations that participants provide during experiments. These explanations can be concurrent (e.g., given while learning about a particular phenomenon or during problem solving) or retrospective (e.g., made after learning has taken place or a problem has been solved). They can be elaborations of given information during learning, verbalizations of accessible thought processes, or justifications of why an answer has been given in a problem-solving situation. The main feature that selfexplanations have in common is that they are verbalizations that a participant provides about their own learning or problem solving. Analogical reasoning is reasoning based on understanding one thing in terms of another. To investigate analogical reasoning ability, proportional analogy problems are often employed. These problems are where two related items are presented together and a third item is presented on its own. The participant has to generate or select an additional item that relates to the third item in the same way in which the first two S 3006 S Self-explanation, Feedback and the Development of Analogical Reasoning Skills items are related. This is often depicted as A is to B as C is to? A simple example is: cat is to kitten as dog is to?; the relation between these items is the name of the young offspring for the type of animal. The correct answer, therefore, is puppy. Theoretical Background The Self-explanation Effect Asking participants to provide self-explanations in learning and problem-solving situations enhances performance in both adults and children. There are two main theories that try to account for the benefits of selfexplanation: a processing account and a mental models account. The processing account suggests that providing self-explanations during learning or problem solving helps participants to avoid focusing too much on surface level features of a problem, the overall goal and rules of a problem, but to concentrate on strategies, subgoals, and evaluation of progress (e.g., BerardiColetta et al. 1995). On the other hand, the mental models account suggests that self-explanations help participants to identify gaps in their knowledge or understanding (e.g., Chi 2000). Once participants have identified these gaps, they can then make the effort to gain the information required to complete their understanding. Development of Analogical Reasoning Skills There is evidence to suggest that analogy is used to reason spontaneously from infancy with a significant increase in children’s ability to reason analogically over the first few years at school (Siegler and Svetina 2002). The three main factors that have been posited to explain this development include: (1) the way children are able to represent relations, (2) an increase in domain knowledge, and (3) maturational changes in high-level cognitive ability. The first factor concerns the idea is that children undergo a “relational shift” (e.g., Ratterman and Gentner 1998), whereby their analogical reasoning changes over time from being based initially on the surface features of stimuli (e.g., objects and attributes) to the inclusion of information about the relations between objects, eventually incorporating whole systems of relations including hierarchically nested relational structures. The occurrence of this relational shift may be related to the second factor, that is, the idea that as children gain more general knowledge their ability to identify relations increases (e.g., knowing that a kitten is the offspring of a cat) such that they are able to use analogy to reason more successfully. Children who lack relevant domain knowledge will incorrectly rely on surface features of a problem rather than the necessary relations. It has also been claimed that working memory plays a pivotal role in the acquisition of analogical reasoning skills. This includes maturational changes in its capacity as well as attentional and inhibitory mechanisms associated with executive functioning. These changes facilitate children’s ability to represent multiple dimensions, which, in turn, gives rise to improved performance on tasks involving more complex analogical mappings. Important Scientific Research and Open Questions The Confound of Feedback Feedback is emerging as an important factor in participants’ problem-solving performance. Participants who receive feedback outperform those who do not (e.g., Ball et al. 2010; Cheshire et al. 2005). It is common in studies that elicit self-explanation for some kind of feedback to be provided to participants, whether it is implicit or explicit. For example, when participants are thinking aloud while learning from official texts, they know the information is correct, and when participants are asked to provide a justification for an answer they have provided, they are often corrected or asked to explain why a different answer is correct. Therefore, an important question to ask is: How do we know that self-explanation per se is the factor that is enhancing performance and not the associated feedback? How do Self-explanation and Feedback Affect the Development of Analogical Reasoning? Several ▶ microgenetic studies have examined the development of children’s analogical reasoning skills using complex proportional analogy tasks. Results provide compelling evidence that self-explanation and Self-explanation, Feedback and the Development of Analogical Reasoning Skills feedback enhance the development of children’s analogical reasoning skills (e.g., Ball et al. 2010; Cheshire et al. 2005; Siegler and Svetina 2002). Children shift from focusing on surface level features of items in the problems to using strategies based on relations between items. These findings are in line with the idea of a relational shift in the development of children’s reasoning skills. Self-explanation has been shown to have limited long-term benefits. Enhancements to children’s performance is observed at the time of providing explanations, but the level of performance drops off when participants are no longer required to provide explanations (e.g., Cheshire et al. 2005). This suggests that selfexplanation may enhance the processing aspects of problem solving; verbalizations may help guide participants to focus on the less superficial aspects of the problem (e.g., item similarity) and employ the most successful strategies based on relations between the items. These findings provide support for the processing account of the benefits of self-explanation (e.g., Berardi-Coletta et al. 1995). Feedback seems to have more long-term benefits. When no longer given feedback, participants continue to perform at the same levels as when they were given feedback (e.g., Cheshire et al. 2005). This suggests that it is feedback (rather than self-explanation) that promotes the completion of a participant’s mental model of proportional analogy. Participants might be keen to improve their own performance and analyze why they were wrong. A more complete mental model means that participants’ understanding is long lasting enough for them to perform well even when they are not being given trial-by-trial feedback. However, feedback is most useful when it is combined with explanation. The combined benefits of self-explanation and feedback lead participants to the greatest levels of understanding (Cheshire et al. 2005; Siegler and Svetina 2002). This is unsurprising if self-explanation is helping participants processing abilities and feedback is enhancing their mental representations. These factors are likely to interact to produce high levels of performance and are unlikely simply to be additive. Furthermore, asking participants to explain why an answer is incorrect has been show to be even more useful that explaining why an answer is correct (e.g., Ball et al. 2010). It is possible that explaining erroneous answers requires higher levels of analysis and, in turn, S 3007 leads to deeper understanding of how to make effective relational mappings. Remaining Challenges There are still many unanswered questions in the area of self-explanation, feedback, and the development of analogical reasoning skills. A content analysis of selfexplanations may reveal further insights into how verbalization helps participants to focus on the essential elements of a problem. Furthermore, similar research needs to be carried out on other analogical reasoning tasks to see if the impacts of explanation and feedback are similar in other areas of analogy and not just proportional problems.

S 3008 S Self-explanations Self-explanations Self-explanations involve the learner generating statements (i.e., elaborations) during learning by explaining the content of the learning materials to themselves. As an example, we could tell learners that “positive reinforcement increases the likelihood of the behavior that it follows.” A self-explanation could be: “Positive reinforcement would need to be something attractive that I would want to receive again.” Self-Guided Learning ▶ Self-directed Learning and Learner Autonomy Self-Organization in Learning ▶ Self-organized Learning Self-organized Learning RENAE LOW, PUTAI JIN School of Education, The University of New South Wales, Sydney, NSW, Australia Synonyms Self-directed learning; Self-organization in learning Definition Self-Handicapping ▶ Procrastination and Learning Self-Inquiry ▶ Creative Inquiry Self-Knowledge ▶ Development of Self-consciousness Self-Maintenance ▶ Physiological Homeostasis and Learning Self-Management ▶ Self-regulation and Motivation Strategies The conceptual framework of self-organized learning was originally proposed and developed by E. Sheila Harri-Augstein, Laurie F. Thomas, and their associates of the Centre for the Study of Human Learning at Brunel University (Harri-Augstein and Thomas 1979, 1983). It was initially a reaction to “cookbooks” for study (taking “good notes,” following the “algorithmic” instructions on the laboratory card, etc.) that flooded the education market, which, according to them, might result in students’ dependency upon the content and structure of their enrolled courses. As pointed out by Harri-Augstein and Thomas (1983), many students are unaware of the processes that attribute personal meaning to the displays of public knowledge offered in classrooms, laboratories, libraries, and workplaces. They assert that student should learn how to learn and unfreeze their fixed habits of reading, listening, talking, writing, thinking, feeling, and doing in order to conduct conscious reflection and constructive review. According to Harri-Augstein and Thomas (1991), self-organized learning refers to the conscious and ongoing activity of learners who are able to apply constructive conversations with themselves and others about the learning process and are skillful in observing, searching, analyzing, formulating, reflecting, and reviewing on the basis of such engagement. Because a number of students, if unaided, are unable to generate effective learning conversations with themselves, supporting tools can be used to facilitate a systematic Self-organized Learning review and remolding of the existing learning strategies and skills. Through learning conversations, students can become self-organized learners, who not only possess the dispositions to improve their own learning processes and outcomes, but also render support to the learning of others. It should be pointed out that the concept of selfdirected learning in a sense is related to, but broader than self-organized learning. Most often self-directed learning is considered as a series of complex educational processes in which learners (a) take initiatives to identify their own learning needs, (b) set up their own learning goals, (c) search resources (including instructors/peers and material) for learning, (d) choose and implement their own approaches to and strategies of learning, and (e) evaluate learning outcomes (Knowles 1975). Basically, there are two types of selfdirected learning: autodidaxy and learner control. Whereas autodidaxy is a self-taught, independent practice in which individuals select their own topic, method, and standards for learning, learner control refers to the process that responsibilities of learning are transferred step by step from experts to the individual student, a continual process closely in line with the description of self-organized learning highlighted by Harri-Augstein and Thomas (1979, 1983, 1991). Readers need to be aware that in the literature, a proportion of researchers have used the term “selforganized learning” loosely or even interchangeably with self-directed learning and self-regulated learning. For instance, in a special issue on “Technology Support for Self-Organized Learners” in the journal of Educational Technology & Society (Kalz et al. 2009), a collection of articles using terms like “self-regulation,” “self-regulated online learning,” “self-directed learning,” “self-direct intentional learning,” “selfdevelopment of competences,” “self-regulating strategies,” and “self-organized learning/learners” were included. This phenomenon of cross-boundary usage of related terms in some research reports should be noted for further conceptual clarification. Theoretical Background The practice of self-organized learning has its deep roots in humanistic, cognitive, and behavioral perspectives (see Harri-Augstein and Thomas 1979). The humanistic underpinnings are largely based on the person-centered approach developed by Carl Rogers, S whose theory of therapy, personal growth, and interpersonal relationships emphasizes three critical conditions for meaningful and resourceful learning to occur: congruence, acceptance, and empathic understanding. Congruence or realness can be achieved by letting students construct their environment for learning and create a system for open reactions (mutual feedback) so that both the student and the tutor (who takes the role as a facilitator) can view the whole picture of this proactive learning state. Acceptance of or respect to students can encourage individuals to express their learning targets. Empathic understanding can help ascertain learners’ problems, constraints, and potentials. According to Harri-Augstein and Thomas (1979, 1983), the self-organized learning approach is further supported by George Kelly’s cognitive theory that focuses on personal efforts to obtain meanings of various encounters by the ways in which a person anticipates certain events that are likely to occur. In other words, ordinary people, just like scientists, continuously construct, test, revise, and develop personal theories of self as well as the world (associated activities) surrounding self. Whereas the personal construct theory was originally used to deal with thoughts and feelings, Harri-Augstein and Thomas (1979, 1983) have applied this theory to education and drawn specific attention to the mechanisms of learning by which personal meaning is searched, constructed, and remolded. The framework of self-organized learning also benefits from the conversation theory developed by Gordon Pask. Based on systems research, the theory is focused on conversations between human beings as participants or between relevant perspectives in one’s human brain. Learning can be attained in a program (i.e., a set of instructions and exchanges) via a language, which is either a natural language or a system of symbolic behaviors. In this interactive process, the conversation is a vehicle for proposing, commanding, questioning, expressing, and exchanging. To facilitate learning, the subject matter should be conversed in the form of explicit entailment structures that exhibit what has been learned and indicate what is to be learned. While acknowledging Gordon Pask’s contributions to bridge the gap between thought and action, Harri-Augstein and Thomas (1979) consider that the formality of his approach places learners in an over-constrained position. Thus in their self-organized 3009 S 3010 S Self-organized Learning learning approach, they encourage learners to gradually take control of their own learning and assist them in building up a repertoire of their personal language and tactics to achieve this. In other words, in the process of learning conversations, the teacher and/or peers assist the learner to clarify essential components of effective learning and support the learner in establishing a personal learning contract (i.e., a self-controlled, structured, achievable outline within an intentional study period). Ultimately, learners are able to act on their new internalized reality, try out and demonstrate new or changed behaviors. Important Scientific Research and Open Questions Self-organized learning per se is a type of Lewinian action research in educational settings, in which individuals interact with educational resources available to them, identify criteria with rigor and validity, and build up personal autonomy. In this learning conversation process, learners reflect on their learning experiences, and their tutor mirrors the reflection and heightens learners’ awareness, thus enabling learners to develop their skills for exploration and to move toward greater competency and creativity. The action research projects of learning conversation have been carried out at three levels of discourse: (a) the learning-to-learn conversation, in which learning habits can be identified, evaluated, altered, reviewed, and rebuilt; (b) the tutorial conversation, in which the longer-term strategic issues of learning, such as the planning of goals, deployment of resources, negotiation of benchmarks, and execution of purposes are discussed; and (c) the life conversation, in which the learner attains greater competence in self-organized learning that can be used to improve quality of life and contribute to individual enterprises and society. For instance, the repertory grid techniques and talkback strategies have been adopted to assist learners to explore, examine, and develop their self-organized capacity to learn from print (Harri-Augstein and Thomas 1979, 1983, 1991). The repertory grid was originally designed by George Kelly in psychotherapy and social psychology to provide clients/subjects with an opportunity to generate and assess their own constructs based on a set of elements listed by those participants. In learning conversational action research, this grid-based method is used to help a learner tap hidden feelings, prejudgments, and habituated assumptions that influence learning. Initially, the learner is aided to explore the area of concern (e.g., having difficulties in taking useful notes); a set of representative elements that are central and meaningful to the problem area are listed; a construct is indicated by emerging clusters (each contains several elements); consensus is made through exchanges between the learner and the consultant; the grids, mapping personal constructs in the reorganized form, are fed back to the participant, who sustains this exploratory process to reflect his or her whole system of feelings and thoughts in relation to particular difficult learning encounters; and a reappraisal of the learner’s approach to the area of concern is thus on the agenda. In order to facilitate self-organized learning, HarriAugstein and Thomas (1979, 1983, 1991) have also used talk-back strategies, such as a behavioral record of reading and a flow diagram of a text, in learning conversations. While reading, many individuals are unaware of the actual cognitive/affective processes that underlie their reading behavior. By means of the computerized device reading recorder, the learner is given the opportunity to check the time spent on each passage, changes in pace, hesitations, skipping, skimming, backtracking, pause, note-making, and so forth. Furthermore, the advisor who actively participates in this learning conversation should offer appropriate interpretations and help the learner acquire relevant perceptual skills to recognize personally significant events in the processes of reading. In addition, the flow-diagram technique can be employed to help the learner to display a multilevel, multidimensional structure of meaning that is relevant to personal experience and understanding. By mapping this complex structure of meanings and relationships onto the records of reading episodes, the learner becomes explicitly aware of the processes in which various interrelated meanings are attributed to corresponding parts of the text. In particular, the underlying factors that cause the learner to slow down, pause, review back, and skip forward can be investigated. The learner and the teaching participant work together to interpret the records of reading behavior and the flow diagram by referring to the original text and the learner’s purpose for reading. Such experiential learning raises the level of selfawareness and brings forth an opportunity for the learner to become a purposeful, self-organized reader. Self-Reflecting Methods of Learning Research S In the era when the mission of education is redefined as lifelong learning and the growth of technological innovations is at an exponential speed, selforganized learning networks and techniques offer tremendous potentials for formal and informal education to be transformed to a learner-centered and selfcontrolled enterprise, which is far beyond the courses and curricula managed by expert providers or constrained by technological tools. For instance, in the online and distributed sectors, Sharma and Fiedler (2007) report that the personal Web publishing system, with its inherent features of personal ownership, individual customization, and public conversation, can foster reflective practices with self and others and thus support self-organized learning. A five-phase procedure can be used to encourage students to combine private and public learning conversations through Weblogs: establishment, introspections, reflective monologue, reflective dialogue, and constructing knowledge artifacts. Such a type of social software allows learners to have multiple roles (being authors, audience, commentators, feedback receivers, revisers, etc.) and thus to take multifaceted perspectives in a wider self-organized learning community. The evidence-based knowledge of human cognitive architecture accumulated in recent decades can also be used to enhance self-organized learning. For instance, the learner and the teaching participant can be involved in a joint venture of customized instructional design, in which a learner’s mental load, preferences, prior knowledge, and other characteristics are taken into account (see, for example, ▶ Modality Effect, ▶ Redundancy Effect, and ▶ Stress and Learning), so that the learner becomes a “scientist” on learning and gains increasing insights into the human information processing. In sum, integration of age-proven pedagogical principles with digital technologies has opened the gate for new forms of self-organized learning.

It is a conscious mental process relying on thinking, reasoning, and examining one’s own thoughts, feelings, and, ideas. It is contrasted with extrospection, the observation of things external to one’s self. In the past years, there has been a growing interest in introspective or self-reflecting methods, such as the “thinking-aloud” interview or stimulated recall, in which a subject engaged in a task, speaks his/her thoughts aloud. This allows studying thoughts without influencing the subject to think too long of what he/she is asked, for example, in questionnaires. Further, written forms of self-reflection are learning diary, learning protocol, and portfolio. From the perspective of learning psychology and educational science, these approaches contribute to the paradigm shift from teaching to learning. Empirical studies in the context of education focus mainly on learning diary, respectively learning journal, protocol, and on portfolio. Learning diaries, for example, have a broad and long tradition in different disciplines. Diaries are applied in clinical psychology, developmental psychology, and medicine. They are research objects in biographical research, developmental, and educational research. Pedagogical diaries, for example, are well known for description and reflection of everyday school life and instructional planning. The use of diaries by researchers shows their versatility as a research tool. Diaries are applied in the evaluation and interpretation of the practice of teaching, training, and learning, especially in action research. The advantages to analyze, for example, students’ learning strategies or teachers’ beliefs are discussed in numerous studies. Moreover, diaries are used in studies on personal identity and life transition, and health. In the past few years, diaries are implemented as learning tools on school and university level, as well. A learning diary allows and supports continuous documentation and reflection of the learning process. Because of its characteristic of continuity the diary may be applied as a time-sampling method to capture courses and changes, for example, of learning strategies, attention, motivation, or emotional experiences over time (Schmitz and Wiese 2006). Complementary to a diary or learning protocol, a portfolio combines more perspectives and functions. Characteristics of a portfolio are, besides self-reflection, documentation of processes and learning outcomes, as well as their evaluation and assessment (Paulson et al. 1991). Generally, five portfolio types may be differentiated (Spandel 1997). (1) The working-portfolio is used to document strengths and weaknesses of a learning process. Therefore, it is mainly used for diagnostic purposes, and may serve for a consultation with respect to learning and achievement. (2) Learning progress and improvement are focused in a developmental portfolio. Learners may easier observe and evaluate their own learning processes, and by that, plan and organize further learning steps more adequately. (3) The presentation portfolio is a collection of the best learning documents or products of a learner he/she selected to demonstrate personalabilities in one or multiple subjects/domains. (4) The fourth type is the evaluation or assessment portfolio. This type of a portfolio helps to document the performance of a learner and has a more formal character. It may serve for information of parents, teachers, and principals of other schools. (5) Finally, the application portfolio focuses on the documentation of qualifications and performance as a certificate. The portfolio is also discussed as an alternative instrument for assessment. The portfolio approach focuses on multiple aims. A portfolio may intend to enhance self-regulated learning by enabling and supporting planning, transposing, observing, and evaluating students learning by themselves. Self-regulated learning is an important condition of lifelong learning, and presumes metacognitive knowledge, and metacognitive strategies. By emphasizing student orientation in school and university, the portfolio approach contributes to the shift from teaching to learning. Theoretical Background Both, learning diaries and portfolios, focus on the participation of learner in planning, realizing, and evaluating their own learning process. Furthermore, communication and refection are important conditions for self-dependent and self-regulated learning. It is assumed that they contribute to lifelong learning. Generally, two main directions of learning diary and portfolio in education are discussed. First, the enhancements of (self-regulated) learning, and second, the aspects of assessment are linked with both Self-Reflecting Methods of Learning Research self-reflecting methods. The application of learning diaries and portfolios may be seen as an example for the shift from teaching to learning. From this point of view educational institutions are seen no longer as a place for knowledge transfer but rather as a wellprepared learning environment to support individual learning processes. Main characteristics are problemcentered and competence-oriented learning demands and tasks, high quality of interactions between learners and teachers, possibilities for cooperative learning, and a well-balanced relation between structured-guided phases and open-individualized phases. The described demands of self-regulated learning emphasize the importance of the ability to reflect on one’s own learning process. Two dimensions concerning reflection may be differentiated. The first dimension describes reflection as a process of a person’s thinking of something. Self-reflection as well as reflection in interaction with other persons is important. The second dimension refers to the object of reflection. It may refer to aspects of the person itself or to aspects that are relevant for other persons, as “external reflection,” or for a whole group, as for example thinking of collective goals or socio-emotional climate. Also the learning environment may be an object of reflection. A third dimension is the aim of reflection which may be retrospective or prospective. As a cognitive process reflection does not need any support by media. But the representing of thoughts by symbols (language, written language, and pictures) gives the possibility to pass on one’s own thoughts and to imagine one’s own thoughts at a later date. In the tradition of Socrates, introspection was applied by the German physiologist Wundt in his experimental psychology laboratory in 1879. Wundt assumed by using introspection in his experiments he would gather information about how minds of human beings are working. In education different approaches to motivate learners to document and to reflect on their learning process have a long tradition. By the end of nineteenth and the beginning of twentieth centuries, the “Reformpädagogik” had already highlighted the potential of learning diary, portfolio, or further reflexive instruments. A person reflects upon himself/herself and the learning process and its outcome to become aware of the sense and purpose of learning. This may foster the S ability of self-regulation, of personal responsibility to make learning more effective. What exactly is reflected has to be specified. It may be personal learning goals, motives, topics and subjects, learning methods and strategies, progress, problems or obstructions, or learning results that are reflected upon. Following the three phases of self-regulated learning as a model of complete action includes planning, transposition, and evaluation. As cognitive, metacognitive, motivational, volitional, and emotional factors interact in all phases of the learning process, continuous reflection is needed to understand and regulate the whole process effectively. Further, it is assumed that the personality of the learner is influenced favorably. A learner may reflect in thought or communicate dialectically. A third option is written reflection. Procedures of continuous, written, and self-reflective documentation of one’s own learning process are assumed to have positive effects on information processing and cognition, and acquisition of knowledge. From a constructivist perspective, writing is an active process of knowledge acquisition, and may be understood as thinking and learning tool. In addition, it may be understood as problem-solving process. Empirical studies revealed, for example, that students who did reflect on what they were doing were more effective in solving tasks in a short time, in adaptive learning, elaborating, and in testing hypotheses than students who were not trained in reflection or avoided reflecting for personal reasons. Recent investigations show a positive effect of reflection on learning strategies and achievement, mainly in the learning process, i.e., the actional phase. Negative effects of reflection were described, as well. Not adequately developed abilities for reflection and a lack of support were related to excessive demand of the learner. Too extended or intensive reflection caused lack of spontaneity or even incapability of action. Finally, the quality of reflection documented in learning diaries or portfolio depends on the learner’s personality, epistemology, individual goals and motives, as also on conditions of the learning environment. It will be more demanding to establish reflexive elements in teacher-centered instruction than in an open and student-oriented learning environment. Consequently, learning environment as well as learning and 3013 S 3014 S Self-Reflecting Methods of Learning Research teaching culture has to be considered for an integration of reflexive elements. Furthermore, support, interaction, and communication with classmates, peers, and teachers have been described as relevant for successful implementation of self-reflexive instruments. Support and guidance to fill-in a learning diary or a portfolio are relevant suppositions for the realization and quality of reflection. Central aspects, such as aims of reflection, and reflection objects are helpful for the learner. One possibility is to offer a written instruction with the main objectives. A second possibility is to formulate open guiding questions or “prompts” focusing on the purpose and aim of reflection. In most of the studies, prompts point to phases, steps, or specific aspects of the individual learning process. Interindividual differences have an influence on the effectiveness of prompts. For example, prompts are not helpful for persons skilled at reflection, but they are experienced as helpful by learners who are not accustomed to reflect (Berthold et al. 2007). The use of learning diaries and portfolios in research studies draws the following picture. Studies applying learning diaries focus first of all on the enhancement of self-regulated learning, and analyze and support the development and use of learning strategies. The improvement of achievement by application of learning diaries is discussed in these studies, as well. Meanwhile, learning diaries are used in school, university education, teacher education, and in-service training. In the past years, digital, electronic, and Web-based diaries and portfolios are applied increasingly often because of multiple advantages of filling-in and analyzing the instrument. How intensively self-reflecting methods are discussed, shows the implementation of electronic portfolios in different countries at university level. The aim is to support students’ competence and lifelong-oriented learning. Especially the portfolio is implemented in research on learning to assess competences and performance in numerous areas, but first of all in writing education (Bangert-Drowns et al. 2004). Furthermore, portfolio as an alternative form of assessment in comparison to traditional approaches of assessment is investigated (Tillema 2001). As a tool for self-assessment, the portfolio is meanwhile investigated, as well. Moreover, some studies analyze the portfolio in examination situations. The majority of research on portfolio as an instrument for improvement of learning and achievement takes the students’ and teachers’ perspective likewise into account. Important Scientific Research and Open Questions The utilization of self-reflecting methods in learning research is a comparably new research area. Therefore, systematical analyses are needed to clarify individual, social, and environmental conditions, influences and effects of learning diaries and portfolios on affective, cognitive, and social factors of learning. Different formats have to be tested, such as open, less or highly structured instruments, paper–pencil, and digital or Web-based versions. The existing perception of potentials of learning diary and portfolio needs to be systematically expanded with respect to different groups of learners, domains, and institutions. Furthermore, it is of interest how implementation of these instruments may be transposed in different educational settings and contexts, as well as in in-service trainings. Up to now, less is known about aggravating or facilitating circumstances. Finally, a comparison of different selfreflecting methods, mainly of learning diary and portfolio, is indispensable to understand and capture the potential and limitation of these approaches.

Self-Reflection ▶ Self-Reflecting Methods of Learning Research Self-Regard ▶ Self-Esteem and Learning Self-Regulated Comprehension ▶ Comprehension Monitoring Self-Regulated Learning S goal-setting, planning, organizing, strategy use, selfmonitoring, and feedback seeking, has been triggered (cf. Schunk 2004). Learning, after all, is regarded as a kind of complex human activity to be done by students rather than to be done for students. In the mid1980s, educational psychologists and pedagogical experts used the term self-regulated learning more frequently and worked on projects associated with its conceptual framework. During the recent two decades, research on self-regulated learning has been flourishing in various areas, ranging from classroom activities to homework accomplishment, from conventional instruction to e-learning, and from training in sports to health education (Hadwin et al. 2010; Jin and Low 2009; Pintrich et al. 1993; Zimmerman 2008). Despite the diversity of studies on self-regulated learning, researchers in general accept the following generic definition developed by Barry J. Zimmerman, Dale H. Schunk, Paul R. Pintrich, Philip H. Winne, and others: self-regulated learning refers to the phenomenon that students systematically activate and sustain metacognitive, motivational/affective, and behavioral processes in order to attain their learning goals in a particular context. As such, self-regulated learning usually involves four distinctive phases, namely, planning, monitoring, control, and evaluation; and the associated activities are ongoing and spiral toward the ultimate goals. Although at the earlier stage of research self-regulated learning was mainly examined in the individual learning context, it should be pointed out that this type of learning can be implemented and tested in both individual and collaborative settings. Theoretical Background RENAE LOW, PUTAI JIN School of Education, The University of New South Wales, Sydney, NSW, Australia Synonyms Self-regulating processes; regulatory learning Self-regulation; Self- Definition Concomitant with the trend of education that started in the 1970s shifting from teacher-centered approaches to student-centered approaches, research attention to individual self-regulatory processes in learning, such as 3015 According to Schunk (2004), the theoretical framework of self-regulated learning is mainly derived from behavioral, information processing, and social cognitive perspectives. Behavioral research shows that operant behavior (a) is likely to occur if reinforced with positive consequences, and (b) can be fostered in the presence of discriminative stimuli. In a learning context, desirable behavior (e.g., completing a quality assignment before the due date) can be nurtured by self-instruction (e.g., establishing a rule of using the period from Monday to Friday between 7 and 9 pm for study only rather than playing the online game World of Warcraft), self-monitoring (e.g., keeping a diary and checking the utilization of planned study periods), and S 3016 S Self-Regulated Learning self-reinforcement (e.g., rewarding oneself a weekend ski trip after the completion of a satisfactory assignment). These three subprocesses form the key behavioral components of self-regulated learning. Information processing theories view human cognitive architecture as an operational model in terms of the organization of information handling and storage. The model comprises sensory memory–working memory–long-term memory components. Working memory (named short-term memory previously), which can hold about five to seven chunks of information for a very short period, is the gateway between sensory input and long-term information storage. From the perspective of evolutionary psychology, the limited capacity and duration of working memory may be necessary to allow only essential but not random, dysfunctional information to be sent to long-term store, thus maintaining the cognitive system’s relative stability and incremental progress. The utility of one’s existing long-term memory (which has no known limit) is a major, effective way to relax the limits in working memory for information processing; and learning occurs meaningfully when there is progressive alterations in the learner’s long-term memory. In other words, learning can be facilitated if relevant prior knowledge stored in long-term memory is activated and then effectively integrated with new information in working memory. If learners possess a high level of metacognitive awareness (what is to be learned, when and how it is to be learned, and so forth) and a set of useful strategies (analyzing, planning, organizing, implementing, adjusting, etc.), the information processing can be enhanced by their purposeful selfregulatory activities. For instance, a student with a certain degree of constructive metacognition may acquire the note-taking skill, use it in lecture, and carefully check the task demands before action. Such initiatives contribute to effective self-regulation. From a social cognition perspective, learning is a process where learners transform their mental abilities and epistemological beliefs into the acquisition of specific knowledge or skills. Self-regulated learning is characterized by its proactive features – the learner not only displays personal initiatives, adaptability, and perseverance, but also actively seeks feedback and help from peers, instructors, and social network. Zimmerman (2008) theorizes that there are several steps that can lead to the desired level of self-regulated learning: (a) observation, in which a learner adopts vicarious learning from a skilled model; (b) imitation, in which a learner replicates a modeled skill while receiving social feedback; (c) self-control, in which a learner independently uses a demonstrated skill on a structured task; and (d) self-regulation, in which a learner is capable to adaptively employ skills to deal with changing tasks in various contexts. Self-regulators tend to have higher self-efficacy, demonstrate more intensive goal-setting activities, and report less negative academic procrastination problems than externally regulated students (Jin and Low 2009; Schunk 2004; Zimmerman 2008). Important Scientific Research and Open Questions Research in the area of self-regulated learning is one of the fruitful areas in modern educational psychology and pedagogy. The following sections attempt to summarize the major progresses and future directions in this domain. Constructs and instruments – Because of the multidimensional features of self-regulated learning, its constructs have been expressed as the degree to which learners proactively pursue their goals through metacognitive, motivational, and behavioral engagement. Basically, there are two categories of measures, aptitude-related and event-related. The aptitude measures are employed to gauge a learner’s relatively enduring attributes related to self-enhanced learning behavior, motivation, and metacognition. The scales in these inventories are often designed to calibrate a person’s responses over time, such as “most of time” or that “is typical of me” (Schunk 2004; Zimmerman 2008). The event-related approach represents an alternative assessment of self-regulated learning, which is regarded as a set of multifaceted, sequential responses over a particular period and in an authentic context. To some extent, an event-related approach that adopts multipoint measures can reflect the sequential dependency of learners’ responses and thus are helpful in evaluating the effectiveness of interventions (e.g., metacognitive skills training) and drawing causal inferences. The most frequently used aptitude-related measures include self-reporting inventories, structured interview, and teachers’ judgments (Pintrich et al. 1993; Zimmerman 2008). Commonly used inventories Self-Regulated Learning include the Learning and Study Strategies Inventory (LASSI) assessing skill, will and self-regulation strategies, the Motivated Strategies for Leaning Questionnaire (MSLQ) assessing learning strategies and motivation, and other shorter questionnaires. Those tailored inventories are useful in collecting cross-sectional information about self-regulated learning on a relatively large scale. Structured interview methodology, with its unique feature to elicit students’ prospective answers, can be used to obtain an insightful view on students’ internal states as well as overt responses. For instance, a team led by Zimmerman (2008) has developed the Self-regulated Learning Scales (SRLIS) as a structured interview format to assess students’ motivation (selfevaluation reactions and self-consequences), metacognition (goal-setting and planning, organizing and transforming, seeking information, and rehearsing and memorizing), and behavior (environmental structuring, keeping records and monitoring, reviewing, and seeking assistance from others), In addition, teachers’ ratings and comments are another type of rich sources to examine the consistency of students’ self-regulated learning and to verify information gathered from other approaches. There is a wide range of event-related measures available for self-regulated learning research, such as think-aloud method, error detection in task performance, trace method, and observation in naturalistic settings. In view of the advancement of information technology, Zimmerman (2008) proposes a number of innovative ways to scrutinize self-regulated learning, including trace logs (frequency, duration, and topics) in computer-assisted learning environments, using a think-aloud protocol in hypermedia environments to record students thoughts and associated cognitive activities while performing a task, structured diary to identify learning processes, observation with multimedia means, and micro-analytic measures and cyclical analyses. Effectiveness of self-regulated learning and student training – On the whole, research endorses the merits of self-regulated learning in terms of personal development as well as learners’ acquisition of academic domain knowledge and skills (Schunk 2004; Zimmerman 2008). For instance, in a recent study undertaken in a secondary school, Grigorenko et al. (2009) found that, in addition to the grade prior to entry and standard admission test scores, aspects of self-regulated learning, S such as academic self-efficacy, academic motivation, academic locus of control, and reasoning skills were also powerful predictors of academic success. The researchers further speculate that high levels of selfregulated learning and analytical abilities may even lead to post-schooling life success. Research indicates that more effort is needed to promote self-regulated learning for ill-structured tasks. There are also preliminary findings in relation to gender, disciplinary, and age differences in self-regulated learning. More and more researchers, instructors, and educational administrators are investigating motivational issues and working on educational programs to enhance motivation and self-regulation skills. In general, efforts are exerted in the aspects of motivational analysis, training, and maintenance. In should be noted that it is more economical and effective to have those interventions embedded in daily teaching and learning practices than separate actions. Teachers’ (and parents’) attitude and teacher training – Students’ engagement in self-regulated learning by no means implies any reduction in teaching load. On the contrary, teachers have an increased responsibility to nurture students’ self-regulated learning competence, and they themselves need to understand critical issues in relation to self-regulated learning, in both theory and practice. Effort has been made to develop a selfreport teacher scale to assess teachers’ beliefs about introducing self-regulated learning in school education. Investigation in preservice teachers’ professional growth shows that the trainees under the condition combining e-learning with self-regulated learning exhibited high competence in self-regulated learning (indicated by behavioral, metacognitive, and motivational factors), sound pedagogical knowledge (e.g., designing a learning unit), and strong studentcentered orientations (e.g., self-construction of knowledge). Research also indicates that it is feasible to promote students’ self-regulatory activities at various levels (from kindergarten children to senior students) by the implementation of self-regulated learning programs for teachers. Likewise, children’s self-regulation is also influenced by parental attitude and support. Concrete work on parental education and school–family–community linkage is much needed to create a pro-self-regulation climate. The role of self-regulated learning in digital environments – The popularity of computer-based 3017 S 3018 S Self-Regulated Learning Strategies education provides both opportunities and threats to the implementation of effective self-regulated learning. On the one hand, students can access a large amount of course information almost without boundaries and at such a high speed that former generations never dreamed of. On the other hand, students may be distracted by nonessential information and lost in the cyber space. We need to construct effective e-learning systems based on the evidence accumulated in cognitive, motivational, and behavioral research, and students should take multiple roles (as users, testers, informants, and design partners) in this process. In this regard, Winne and associates have made a successful attempt to produce a versatile software system (gStudy) and create an interactive digital environment for self-regulated learning (e.g., Hadwin et al. 2010). Detailed trace data, such as concept maps, learners’ notes and uploaded material, can be unobtrusively collected. Data collected from interactive environments are conducive to ascertaining the “blind spots” in selfregulated learning studies, such as active strategies being adopted at different stages, social aspects of learning processes revealed from online dialogue, and indicators of changes in students’ interaction throughout e-learning. Research in this direction is promising and challenging. Hadwin, A. F., Oshige, M., Gress, C. L. Z., & Winne, P. H. (2010).

Self-regulated learners initiate and direct their efforts to learn and are, therefore, active participants in their own learning processes. Theoretical Background Self-regulation is a fairly new focus area first appearing in psychological research journals during the 1980’s. One aspect of this construct, self-regulated learning, has been described from various theoretical perspectives, the most prominent being: operant, information processing, developmental, social constructivist, and social cognitive. Operant Theory The operant theory of self-regulation is based on the work of B.F. Skinner. Operant behavior is behavior whose occurrence depends on the resulting environmental consequences. A behavior becomes more likely to occur if it results in either positive or negative reinforcement and less likely to reoccur if it results in punishment. Behaviors can also be influenced by events occurring prior to the behavior. Prior events, or antecedent stimuli, that are predictive of reinforcement can become discriminative stimuli. If an individual correlates the discriminative stimuli to subsequent reinforcement, the discriminative stimuli can cause the individual to behave in a particular way due to the increased likelihood of reinforcement. Self-regulation as viewed by operant theorists is therefore based on two types of controlling stimuli: those that occur before the behavior, antecedent S 3019 stimuli, and those that result because of the behavior, reinforcement, or punishment. In this perspective, the individual determines the behaviors to regulate corresponding to the discriminative stimuli. The reoccurrence of these behaviors is based on whether the performance matches the discriminative stimuli, and subsequent reinforcement received. Those behaviors that are reinforced are more likely to occur again. Information Processing Theory Information processing theorists depict learning as the transfer of information from short-term memory into more permanent storage of long-term memory. To do this effectively, individuals need to utilize organizational learning strategies to connect new information to prior knowledge, making learning more meaningful. From this standpoint, self-regulatory processes consists of the individual comprehensively assessing the learning task to determine the desired outcomes, evaluate their personal capabilities and current knowledge, then determine the appropriate cognitive strategies that will effectively transfer information into long-term memory. In this perspective, the individual maintains continuous awareness, or metacognition, of their progress so that he or she can adjust his or her performance in order to attain the desired learning goal. Developmental Theory Self-regulation in this perspective focuses on the evolution of control that learners execute on their thoughts, behaviors, and affect. An individual’s progression toward becoming self-regulated is presumed to be dependent on the growth of their cognitive skills. Developmental theorists suggest that selfregulatory behaviors are introduced to the individual through external, social sources, such as parents. As the individual’s cognitive development progresses, these skills tend to become internalized and controlled by the individual. By modeling behaviors of parents and teachers, novice learners can begin to acquire and utilize self-regulatory behaviors. After continued guidance, feedback and reinforcement, these skills tend to become more automatic. Instead of being an exact replication, individuals may exhibit behaviors that generally imitate the models behaviors, thereby indicating a transition to self-control. As self-regulatory skills advance, the individual may seek out teachers and S 3020 S Self-regulation and Motivation Strategies mentors to assist them in refining these skills; however, over time, this may occur less frequently. Social Constructivist Theory The social constructivist perspective of self-regulation is founded on the theories of cognitive development regarding change and continuity. A central tenet of this perspective is that learning is considered to be an inherent need. Individuals continuously seek new information and attempt to develop understanding by imposing meaning based on prior knowledge and experiences. This understanding is continuously transforming through input of new information, cognitive reorganization, reflection, experience, and social guidance. Learning may be constrained at times, however, due to the individual’s current level of knowledge and skill. It is at this point, characterized by Vygotsky as the “zone of proximal development,” that the individual requires assistance from a teacher or advanced peer in order to proceed. As the individual continues to reflect and reorganize information, they are intrinsically motivated to acquire new information. This reexamination of self, behavior, and knowledge are consistent with the major components of self-regulated learning. Social Cognitive Theory The social cognitive perspective of self-regulation focuses on the interaction of personal, behavioral, and environmental processes. Because these factors are continuously changing and affecting the learning situation, the individual needs to constantly monitor feedback, be metacognitively aware, and formulate strategic adjustments. This triadic depiction of self-regulation provides for a cyclical, open feedback loop that allows for both reactive and proactive increases in learning and performance. Self-regulatory processes in this perspective consist of forethought, performance, or volitional control, and self-reflection. The forethought phase consists of task analysis goal setting, strategic planning, as well as assessment of self-motivational beliefs such as self-efficacy, and outcome expectations. The performancevolitional control phase involves aspects of self-control and self-observation. The third phase, self-reflection, includes the processes of self-evaluation and selfjudgment. Social cognitive theorists believe that self-regulation is domain specific consequently processes may vary across learning situations. While the overall processes of self-regulation are maintained, individuals need to have flexibility in adapting these processes to specific learning situations. Inherent in this framework is the individual’s confidence, or self-efficacy, in their ability to adapt their behaviors to unique situations. Achievement Goals Achievement goals are the underlying reasons or purposes for an individual’s learning behaviors. Essentially, goals represent the importance that an individual assigns to a learning activity. Achievement goals provide individuals with a means not only to define their successes and failures but also how they may possibly react to the outcomes of their efforts. Highly self-regulated individuals typically establish both process goals as well as outcome goals. Accomplishment of process goals provides the individual feedback on their performance and serves as indicators of progress toward the overall achievement goal. The selection of a particular achievement goal by an individual creates a structure of consequent achievement behaviors. Depending on the goal adopted, individuals utilize varying methodologies to gather situational data to determine the appropriate strategies for success. An individual’s goal orientation establishes a framework of thoughts and behaviors, such as asking relevant questions and seeking information that will enable the individual to attain the goal. Goal orientations also elicit different motivational processes. In general, goals are considered to be the cognitive link between motivation and behavior. Motivation Psychologists posit that motivation is a core construct and a component of most human activity. The psychological processes inherent in motivation consist of individuals being moved into action because of a need or desire that is at least partially unfulfilled or below expectations. This discrepancy initiates action in a particular direction or toward a goal. The intensity of effort is dependent on the goal. While goals serve as the key driver for action, goal difficulty and importance are associated with the psychological environment that exists at the time, which consists of perceptions, knowledge, skills, abilities, and attributions. Self-Regulatory Self-Efficacy There are many motivational theories related to learning, each with its own description of the constructs. Despite the variations in terminology, many similarities exist. In general, motivation influences an individual’s behavior in regard to direction, effort, persistence, and accomplishment of goals. Motivation is not a stable trait but is dynamic in that it is affected by both internal and external forces, varies among and within individuals, and is context dependent. As such, an individual’s motivation may vary as a function of subject matter domains and even by instructors and classroom situations. Regulation of motivational strategies is an important facet of self-regulated learning. Similar to the regulation and selection of cognitive strategies appropriate for accomplishing a learning task, individuals also regulate motivational strategies that influence choice, effort, and persistence. In addition, the particular motivational strategies adopted may also influence the use of specific cognitive strategies. Self-regulated learning is often considered to be the synthesis and utilization of both cognitive and motivational strategies. As described, self-regulation finds its basis in various theoretical frameworks; therefore, many of the processes may be referred to by different terms. The general context remains the same, however. Selfregulation is a systematic process of aligning behavior, cognitive strategies, goal establishment, self-assessment and feedback to attain a desired learning or achievement goal. The processes of self-regulation are interrelated and function in a cyclical manner, whereby feedback from previous experiences has been found to influence current efforts. Important Scientific Research and Open Questions While there has been a great deal of research focusing on self-regulation, there is still confusion as to the key components of the construct and related subprocesses. Work continues to focus on determining these processes as well as the distinct steps or phases involved in self-regulated learning. There has also been much discussion on the development of self-regulatory skills, and the demographic, cultural, and socioeconomic implications that may influence acquisition of these skills. Additionally, self-regulatory processes are linked with content domains; therefore, investigations continue to focus on the nuances of self-regulation in S 3021 various content areas, and the transferability of these skills to unique situations. As studies in this construct progress, it may be beneficial to refine research designs and statistical techniques in order to capture the dynamic interactions of the processes of self-regulated learning.

Thus, self-schemas vary from person to person but within a person they are relatively stable and persistent. Further Reading Cervone, D., & Pervin, L. (2008). Personality theory and research.

Self-Worth ▶ Self-Esteem and Learning Semantic Classification ▶ Concept Formation: Characteristics and Functions Semantic Knowledge Conceptual knowledge, or knowledge about the meaning or understanding of information. Semantic knowledge is not linked to any specific episodic event, but rather is similar to procedural knowledge in that it is typically accessed without conscious awareness. An example of semantic knowledge would be the ability to indicate if an apple is a fruit or a vegetable. Semantic Memory in Profound Amnesia BRENDAN D. MURRAY, ELIZABETH A. KENSINGER Department of Psychology, Boston College, Chestnut Hill, MA, USA Synonyms Category learning; Memory loss Definition Semantic memory refers to memory for general factual knowledge: for example, knowing the definitions of words, the names of world leaders, and so forth. Semantic memory can be contrasted with episodic memory, which refers to memory for specific personal events: a meeting we went to last Tuesday, what we had for breakfast this morning, or a movie we saw last month, for example. Semantic information differs from episodic information in that semantic memory is devoid of context; although we can recall specific who/what/when/where details about our vacation to France (episodic), no such details need come to mind when we retrieve the meaning of a French word or indicate that the Eiffel tower is in France (semantic). The memory for this semantic information does not require us to remember the context in which we learned the information and, in fact, we often cannot remember the details associated with our acquisition of this type of general factual knowledge. Semantic memories can be further divided into personal and public semantic memories. Public semantic memory is knowledge that certain public events occurred: knowing that Barack Obama was elected president of the United States, for example. Personal semantic memory is knowledge that personal events occurred: knowing the city in which you were born, or knowing that you graduated from college, for example. These memories are semantic, rather than episodic, because they are stripped of context: knowing that Barack Obama was elected does not require that you remember how many votes he received, where he gave his acceptance speech, and so forth. Similarly, knowing that you are a college graduate probably does not require that you recollect your graduation day, and knowing the city in which you were born does not indicate that you can Semantic Memory in Profound Amnesia remember the episodic details of your first days of life. However, there is some disagreement over the extent to which personal semantic memories are devoid of episodic details. Some researchers argue that personal semantic memories (e.g., knowing that you graduated from college) necessarily entail some episodic detail or, at least, are the product of some episodic knowledge (e.g., you know you are a college graduate because you attended the ceremony and received the diploma). Other researchers, however, state that it is possible to recall such knowledge about oneself in the absence of any memory for the contextual detail. One way to examine the relation between episodic and semantic information is to look at how the two are affected in conditions such as amnesia. Amnesia refers to a state in which memory for information or experience is damaged or lost. Amnesia can arise from either organic means (such as traumatic head injury or ▶ neurodegenerative disease) or from psychogenic means (such as memory loss from depression). Organic types of amnesia, which this article will focus on, are often the result of damage to parts of the brain called the ▶ medial temporal lobes. A distinction is made between anterograde amnesia and retrograde amnesia. In anterograde amnesia, the ability to acquire new information is impaired, but access to information that was already learned remains intact. In retrograde amnesia, access to information that had been previously learned is impaired or lost, although new learning can still occur. It is believed that the most common form of amnesia is anterograde with some degree of retrograde amnesia; these patients are profoundly impaired at learning new information, and often show some (lesser) degree of impairment for recollecting old information. This article will focus on this latter type of amnesia as most of the extant scientific literature describes this type of amnesia. Medial temporal-lobe amnesia can differentially affect the acquisition and recollection of episodic and semantic information. Typically, these amnesic patients show profound impairment for both learning and retrieval of episodic detail (although the magnitude of the retrieval deficit is debated), and also some impairment for learning new semantic information (such as the names of people who became famous after the onset of amnesia). However, the retrieval of semantic information is usually relatively preserved. S 3023 Theoretical Background Semantic memory can be probed in a number of ways, one of which is to test naming ability. The Boston Naming Test, for example, asks people to name objects depicted by line drawings. These items may range from easy to name (e.g., “bed” or “tree”) to difficult (e.g., “protractor” or “abacus”). Vocabulary tests, which ask people to either define words or to select synonyms for words, are also frequently used. General world knowledge may also be tested. The Comprehension subtest of the Wechsler Adult Intelligence Scale, for example, asks participants what should be done if one finds a sealed, stamped, and addressed envelope lying on the sidewalk. While both acquisition and retrieval of episodic information appear to be profoundly impaired in amnesic patients, acquisition of semantic knowledge is typically more impaired than retrieval. Indeed, amnesic patients often perform normally (or, no worse than they did before their amnesia) on tests of verbal or lexical intelligence: providing definitions, completing sentences, generating synonyms, and generating exemplars in a category (for example, given the category “zoo animals,” being able to name animals typically found in zoos), to name a few. However, patients with amnesia have shown varying degrees of difficulty in learning new semantic information. In 1988, John Gabrieli and colleagues showed that a group of amnesic patients could not learn the meaning of English words that they did not know prior to their amnesia. Bradley Postle and Suzanne Corkin showed that if new vocabulary words were only encountered infrequently, amnesic patients showed no retention of those words. Conversely, William Hirst and colleagues describe a patient, C.S., who was able to learn a new language despite having anterograde amnesia. Other researchers have shown that patients with anterograde can learn computer terminology even with no prior computing experience, and other patients show the ability to recognize famous persons who were not famous before the onset of amnesia. Although researchers may disagree about the degree to which semantic learning is impaired in amnesia, there is agreement that the acquisition of new semantic information is a slower and more laborious process for those with amnesia than for those without it. This behavioral dissociation between impaired semantic learning and relatively spared semantic memory retrieval suggests that the medial temporal lobes are S 3024 S Semantic Memory in Profound Amnesia necessary for normal semantic learning but not necessary for the retrieval of semantic information (as will be discussed in more detail in the following section). Important Scientific Research and Open Questions Much of the important scientific research on amnesia has come from patients with damage to medial temporal lobes. Possibly the most famous such case is that of patient H.M., who in 1953 had his medial temporal lobes removed to try and treat his severe epilepsy, which had not responded to any other type of treatment. As later reported by H.M.’s surgeon, William Beecher Scoville, and neuropsychologist Brenda Milner, H.M. exhibited profound anterograde amnesia, as well as limited retrograde amnesia for events in the few years preceding his surgery. H.M. could no longer commit personal events to memory, and he showed impairment in learning new semantic information. However, H.M.’s retrieval of semantic information was relatively intact. In 2001, Elizabeth Kensinger, Michael Ullman, and Suzanne Corkin showed that on tests of semantic memory – assessing vocabulary, general world knowledge, the ability to identify famous historical figures, etc. – H. M. performed as well as age- and education-matched control subjects. Given the same tests over the course of several decades, H.M.’s performance did not decline, further evidencing that his ability to retrieve semantic knowledge was not disrupted by his surgery. Martial Van der Linden and colleagues also demonstrated preserved semantic memory retrieval in patient A.C, who was able to name persons who were famous before the onset of his amnesia as well as control participants could. Importantly, H.M. and A.C., as well as other amnesic patients, also demonstrate some ability to learn new semantic information. H.M., for example, could learn that Woody Allen was an actor and comedian, even though Woody Allen did not become famous until after H.M.’s surgery. In the mid-1990s, A.C. could identify the current president of the United States and Prime Minister of Belgium (Bill Clinton and Jean-Luc Dehaene), even though those men were not known political figures at the onset of A.C.’s amnesia in 1977. The magnitude of information learned by medial temporal-lobe amnesic patients is usually far from normal, however, and so current research is examining what features of the information may affect whether or not amnesic patients can retain the new knowledge and what processes may support the learning in these patients. In terms of the information that can be learned, one possibility is that amnesic patients have an easier time learning new semantic information when that information is personally relatable and can be anchored to preexisting knowledge. As noted above, some researchers had little success in teaching patients new vocabulary words. However, Brian Skotko and others showed that H.M. was able to learn that a vaccine developed by Jonas Salk (which was not produced until after H.M.’s surgery) could prevent polio because polio was still common when H.M. was young and therefore personally relevant. Similarly, A.C.’s family indicated that he was always very interested in politics, which may have made the names of new political figures easier to retain in memory. To this end, it has been suggested that the presence of ▶ schemas – mental constructs that help to organize information – for certain domains of information may facilitate semantic learning in that domain. Amnesic patients may retain schemas for information that was well known to them prior to the onset of their amnesia and that is personally relevant, and they may be able to anchor new information to those pre-existing schemas. The cognitive and neural processes that support the learning and retrieval of semantic information are still under investigation. At a cognitive level, it may be that amnesic patients cannot learn semantic information through the one-trial learning processes that assist healthy individuals. Amnesic patients may need extensive repetition of information to learn the new knowledge, and it is even possible that they are benefiting more from ▶ implicit learning of the information than from ▶ explicit learning. At a neural level, there is some evidence that the ▶ lateral temporal cortex and ▶ parahippocampal gyrus may play a role. These regions were intact in patients H.M. and A.C. but were damaged in patient E.P., tested by Peter Bayley and Larry Squire. E.P. could not demonstrate any new semantic learning; however, E.P.’s damage was so diffuse as to make it difficult to conclusively ascribe semantic learning to these regions.

Semantic Networks PABLO PIRNAY-DUMMER, DIRK IFENTHALER, NORBERT M. SEEL Department of Education, University of Freiburg, Freiburg, Germany Synonyms Active structural network; Associative networks; Conceptual graphs Definition Semantic networks are a logic-based formalism for knowledge representation. Semantic networks are graphs which are constructed from both a set of vertices (or nodes) and a set of directed and labeled edges. The vertices or nodes represent concepts, and the edges represent semantic relations between the concepts. Knowledge about accepted meanings should be processed in adjacent regions of the semantic network. Therefore, S 3025 semantic networks are often termed “associative networks.” They directly address issues of information retrieval, since the associations between concepts define access paths for traversing a structured knowledge base. Another important feature of this kind of representation schema is the availability of organizational principles, such as generalization, instantiation, and aggregation. A third characteristic feature is the graphical notation that enhances their comprehensibility. Indeed, the chief advantage of graph notations is the ability to show direct connections between vertices. Semantic networks are widely applied in the field of Artificial Intelligence (especially language processing) but they also found acceptance as psychological models of the human semantic memory. However, they must be distinguished from concepts maps which are defined as external network structures aiming at the organization of knowledge for teaching and learning (Novak 1998). Theoretical Background The idea of depicting semantic structures, which include concepts and relations between concepts, has its source in two fields: semantics (especially propositional logic) and linguistics. From a psychological point of view, semantic networks are representation schemas which operate on the hypothesis, that intelligent systems memorize knowledge by means of specific propositions about the conceptual information that is inherent in the issue to be remembered. More specifically, semantic networks are schemas for representing declarative knowledge which is considered as a set of facts that can be represented as a data structure. The facts describe elements of the world (objects, events), relations between the elements as well as states of the elements. At the beginning, there was Quillian’s (1968) work in Semantic Memory. Quillian used a network structure to model human verbal memory. His idea was to get a “humanlike use” by processing a network of associations with a spreading activation search. The nodes of Quillian’s networks represent concepts which were described by their relations with other concepts. Quillian distinguishes several types of relations, such as set operators (subclass, modification), semantic cases (subject, object), and logical operators (and, or, not). Some years later, semantic networks had been S 3026 S Semantic Networks developed also by Anderson and Bower (1973) as a representation schema for modeling human associative memory, and similarly, Norman and Rumelhart (1978) operated with semantic networks in modeling semantic memory. A major characteristic of these early approaches as well of follow-up approaches (e.g., Aebli 1981) was the “linguisticizing” of semantic networks to adjusting their notation to linguistics (Mylopoulos and Levesque 1984). This corresponds with the idea of Richens in 1956 to use semantic networks as an “interlingua” for the computation of natural languages. The emergence of Artificial Intelligence as a prospering field of informatics then saw a rapid increase in the development of and research on semantic networks as “tools” of conceptual modeling in cognitive science, machine learning, and programming languages (see for an overview Brodie et al. 1984). Today, semantic networks come in such a wide variety of forms and are used in so many ways that it is difficult to describe what is common to all of them. Actually, many different representation schemas are called semantic networks but they minimally share a common notation based on graph theory. Features of Semantic Networks In its most basic form, a semantic network represents declarative knowledge in terms of a collection of objects (nodes) and binary associations (directed labeled edges), the former standing for individuals (or concepts of some sort), and the latter standing for binary relations over these. According to this view, a knowledge structure or knowledge base is a collection of objects and relations defined over them, and modifications to the knowledge base occur through the insertion or deletion of objects and the manipulation of relations. Representation of knowledge by means of a semantic network corresponds with a graphical representation where each node denotes an object or concept, and each labeled edge (n1, R, n2) indicates that (n1, n2) 2 R with R being one of the relations used in the knowledge structure. Despite the differences between semantic networks, three types of edges are usually contained in all network representation schemas: (a) Generalization (is-a, ako) connects a concept with a more general one (e.g., bird – is a – animal). The generalization relation between concepts is a partial order and organizes concepts into a hierarchy. (b) Individualization (instance of, member of) connects an individual (token) with its generic type (e.g., Laura – instance of – bird). (c) Aggregation (part-of, has-as-part) connects an object with its attributes (parts, functions) (e.g., wings – part of – bird). Another method of organizing semantic networks is partitioning which involves grouping objects and elements or relations into partitions that are organized hierarchically, so that if partition A is below partition B, everything visible or present in B is also visible in A unless otherwise specified. Partitions are useful in representing time, hypothetical worlds, and belief spaces. Development of Semantic Networks Despite their differences, semantic networks conform to their foundation on predicators (i.e., predicateargument structures) which can be depicted in conceptual graphs. A predicate is a general function which specifies the relations which exist between a certain number of domains (or arguments): P (Domain1, Domain2, Domain3, . . . Domainn). The term predicate refers to the function itself, whereas the term domain (or argument) refers to the modality of concepts which can be applied within predicates. Predicates refer to coherences and concepts to individuals of a domain. The concepts can be considered as constants that take the place of the variables of the predicates. Thus, concepts create depictions of single events or states of the cognized world. Actually, the nodes of semantic networks are abstract parameters which appear at that place where the set of relations coincide to constitute a concept. Usually, the nodes and relations are denoted by expressions of natural language that constitute a form of information and must also be represented in some way. This linguistic information is often enclosed in a vocabulary. If a concept represented by a node has a name in terms of natural language then a relation traverses to exactly the content of the vocabulary that contains the applicable words. This can be illustrated as in Fig. 1. The interpretation of a relation which connects two nodes depends on both the label and the direction of passing through the relation. As a consequence, it is possible to apply various measures from graph theory to track the development of knowledge representations (see for example Ifenthaler et al. 2010).

Fig. 1 Example of a semantic network with vocabulary (Rumelhart and Norman 1978, p. 55) Important Scientific Research and Open Questions Graph-based knowledge representation is undoubtedly the most popular modality of representing semantic knowledge in current cognitive science and informatics (Chein and Mugnier 2009). On the one hand, semantic networks and conceptual graphs aim at modeling semantic memory due to the basic assumption that information can be represented with the help of active structural networks (Norman and Rumelhart 1978). On the other hand and due to their origins in linguistics, semantic networks find a widespread application in the field of natural language processing in Artificial Intelligence. In early semantic networks the nodes stood for linguistic terms. This resulted in a propagation of types of edges and, in consequence, complicated their processing. A solution was found by (a) a limitation of edge types to few but semantically exactly defined relations and depiction of content-related edges through nodes, and (b) by the introduction of so-called semantic primitives. They play an important role within the model of Conceptual Dependency Structure of Schank (1980) which, however, is not a semantic network. Rather, it operates with conceptualizations which attribute actions to cases. Since their emergence in the 1970s, semantic networks experienced manifold variations and elaborations. Although there is no standard procedure for developing semantic networks, most of them agree on the general principles as described, for instance, in detail by Sowa (1984) who furthermore introduced a taxonomy of network representational schemas: (a) Definitional networks are based on is-a relations between the nodes and organize a generalization or subsumption hierarchy with its major characteristics of inheritance of features from types to tokens. (b) Assertional networks are designed to assert propositions. They often serve as models of the conceptual structures underlying the semantics of natural languages. (c) Implicational networks operate with the relation of implication for connecting nodes. They may be used to represent beliefs, causalities, or simple inferences. These three network representation schemas can be found in nearly each field of application in artificial intelligence and psychology. However, network representation schemas in the field of AI usually go beyond these types of semantic networks because intelligent systems, natural or artificial, must be able to draw inferences and to learn. Therefore, the taxonomy of network representational schemas include also the following: (d) Executable networks which contain mechanisms for passing messages, searching for patterns and S 3028 S Semantic Networks associations, and most notably for performing inferences. Often these inferences are based on default reasoning. (e) Learning networks develop or extend their representations by acquiring knowledge from examples. The resulting new declarative knowledge may change the former network by adding and deleting nodes and edges or by modifying numerical values, so-called weights that are associated with the nodes and edges. Finally, there are hybrid networks which combine two or more of the previous techniques, either in a single network or in separate, but closely interacting networks. Learning Networks From the perspective of Artificial Intelligence, learning systems are necessary for adjusting representational schemas to changing environments. More specifically, learning networks adaptively respond to new information by modifying its representations so that the intelligent system, natural or artificial, is capable to adjust more effectively to its environment. Systems that use network representations can modify the networks in three ways: First, by means of rote learning that simply adds new information to an available semantic network without substantial changes to it. Second, in some networks the vertices and edges have weights that can be changed. In implicational networks, weights might represent probabilities which could increase due to repetitions of the same type of network. Third, learning can aim at restructuring a network with the aim to basically change the overall structure of the network. This form of learning is certainly the most complex form of learning networks and also the most difficult because the extent and quality of structural changes are infinite. Since the seminal work of Collins and Quillian (1969) who investigated the interaction between a quite simple structure for semantic networks and complementary processes the research on the development of semantic exploded. Models of associative semantic networks regularly contained some kind of spreadingactivation process and were widely applied to predict performance in experimental memory retrieval tasks as well as to explain priming and interferences in information processing (Anderson 2000). As a result of this research the processes involved in the formation and search of semantic memory are well understood now whereas research on the large-scale structure of semantic memory and its interactions with knowledge acquisition and retrieval is at its beginning. Steyvers and Tenenbaum (2005), for example, explored the largescale structure of three types of semantic networks (word associations, WordNet, and Roget’s Thesaurus) and could show that these semantic networks have a small-world structure which is characterized by sparse connectivity, short average path lengths, and strong local clustering. Furthermore, Steyvers and Tenenbaum described a simple model for semantic growth, in which each new concept is connected to an existing network by differentiating the connectivity pattern of an existing node. This model also provides a mechanism for the effects of learning history and performance in semantic tasks. Another line of current research on semantic networks is concerned with the comparison of ontology with semantic networks for knowledge representation (e.g., Salem and Alfonse 2008).

Semantic Technologies and Learning THANASSIS TIROPANIS1, HUGH C. DAVIS1, STEFANO A. CERRI2 1 Web and Internet Science group, Electronics and Computer Science, University of Southampton, Southampton, UK 2 LIRMM: Laboratory of Informatics, Robotics and Microelectronics, University Montpellier2 & CNRS, Montpellier Cedex 5, France Synonyms Knowledge representation and reasoning and learning; Linked data and learning; Semantic web and learning Definition Semantic technologies provide for the expression of meaning of resources such as content, software, systems, people, and communities in machine processable S 3029 formats with the help of ontologies. Ontologies provide the vocabulary for describing resources and their relationships (Gruber 1993; Musen 1992). Based on the meaning of resources, semantic technologies can draw conclusions and enable better resource discovery and matching. In a learning context, the potential of semantic technologies translates to a number of affordances. The types of resources involved in formal or informal learning environments could include learners, teachers, software, services and content. Given the description (or annotation) of these resources with the help of ontologies, it is possible to support more efficient discovery of learning resources, sequencing of relevant learning material, adaptation of learning experiences to match learner profiles, formation of groups for teaching learning activities, collaborative construction of knowledge, recommendation of learning resources and activities, and assessment. A number of ontologies are developed in the learning domain in order to support these applications with the help of reasoning software. Theoretical Background Semantic technologies for learning draw from work in Knowledge Representation and Reasoning and have been significantly influenced by developments in the Semantic Web community (Berners-Lee et al. 2001). The Semantic Web vision has been considered “inevitable” and its impact on education significant (Ohler 2008). With the help of ontologies, semantic technologies can support knowledge representation and reasoning. There are a number of ontology languages to address the tradeoff between how expressive an ontology language is and the performance of reasoning based on resources annotated with this ontology language. Resource descriptions in more expressive ontology languages could potentially let us perform advanced reasoning and draw more conclusions about resources, at the cost, however, of increased computation and potentially reduced performance. For example, some ontology languages let us use transitive properties when describing how resources relate to each other, which can provide for more powerful reasoning. Consider an ontology for the domain of language education. We could identify concepts such as student and class and relationships that express that S 3030 S Semantic Technologies and Learning a student attends one class only or that a student is a classmate of another student; one could also specify that the relationship “is a classmate of ” its transitive (i.e., if A is a classmate of B and B is a classmate of C then A is a classmate of C). Given this ontology, one can annotate (mark up) specific resources as instances of ontology concepts. For example, one could mark up each of “Alice,” “Bob,” and “Eve” as instances of a student and “French” as an instance of a class; one could also state that “Alice” is a classmate of “Bob,” that “Bob” is a classmate of “Eve,” and that “Eve” attends “French.” Given this annotation and the ontology, it is possible to draw conclusions with the help of software; in this example, software could infer that “Alice” attends “French” and that “Alice” is a classmate of “Eve” even if this information is not explicitly stated in the annotation. The power of knowledge representation and reasoning bears significant promise for learning. In addition, the well-formed description of resources with the use of lightweight or more expressive ontologies bears potential for interoperability and data integration. This has led to research on the use of semantic technologies in a number of areas related to learning. Semantic Technology Affordances The promise of semantic technologies in learning has been identified as an important aspect of Technology Enhanced Learning (TEL) in both formal and informal learning settings. The ability of semantic technologies to match people, content, and communities that are involved in learning processes is central in all these areas. Matching learners to learning resources has led to work on the integration of semantic technologies Learning Management Systems (LMS), Learning Content Management Systems (LCMS), or Virtual Learning Environments (VLE). The role of semantic technologies in these domains is on discovering, sequencing, or adapting learning material based on the learner profile and learning outcomes. Semantic technologies have been considered in the context of collaborative building of knowledge and learning material by means of collaborative ontology building, topic maps and semantic wikis. Collaborative ontology building tools have also been developed to that end. The use of semantic technologies to match learners to other learners or teachers has been considered in group-formation systems in formal learning and informal learning settings. In vocational training, semantic technologies have been proposed to form groups of learners with similar or supplementary competencies. In informal learning, successfully matching learners based on their profiles and their learning objectives using semantic technologies has been pursued. Another significant advantage of semantic technologies is in matching content and people involved in learning processes on a large scale: a larger pool of people and content increases the chances of accurate matching. In this respect, the semantic description of resources available in repositories of reference material has been used for advanced content discovery. Semantic applications to support critical thinking and argumentation by enabling the discovery of material in support or against a certain argument are also being explored. At the same time, aggregating and processing information about people and their activity using semantic technologies has led to work on expert matching tools and query answering. Ontologies for describing relationships among people such as the Friend-of-a-Friend (FOAF) ontology enable additional tools on discovering people and supporting informal learning processes. Semantic technologies can support a number of processes in formal education institutions such as assessment. In the environment of assessment semantic technologies can help in preparing appropriate assessment material that matches certain assessment criteria or in the analysis of text that is submitted as part of assessment; there are examples of use of semantic technologies for both summative and formative assessment. Semantic technologies can also support wellformed description of resources in a formal education environment and address interoperability and data integration requirements inside and across education institutions. In the context of formal education, the data interoperability and integration affordances of semantic technologies can support efficient systems for curriculum design, development of learning material, and collaboration among the people involved in teaching and learning activities. Building Semantic Technologies Different approaches can be followed when it comes to developing semantic technologies in a specific domain. Semantic Technologies and Learning One can consider a top-down approach where the use of an ontology or a set of ontologies are agreed first before the annotation of resources and the deployment of applications. An alternative approach gives priority to exposing data sources using lightweight vocabularies first, in order to enable data interoperability and integration before considering more complex ontologies in the context of specific applications. The latter view is central in the linked data movement (http://linkeddata. org/), which proposes practices for exposing and connecting structured data on the Web (Bizer et al. 2009). The Linked Data movement supports the exposure of data sources in lightweight vocabularies such as RDF (http://www.w3.org/RDF/) in order to allow for the emergence of intelligent applications that will make use of the exposed data. The value of semantic technologies and linked data in terms of well-formed description of resources, data interoperability, and data integration in the UK higher education sector has been highlighted in a number of reports (Tiropanis et al. 2009). The types of semantic technologies that are related to learning and which can benefit from the linked data approach include: ● Collaborative authoring and annotation tools ● Searching and matching tools based on linked data resources (e.g., expert finders) ● Repositories and VLEs that import or export their data in linked data formats to support learning resource discovery In parallel to the Semantic Web vision, there are proposals for a Pragmatic Web (http://www. pragmaticweb.info), in which the description of the meaning of resources is based not just on the semantic constructs and their relations as defined in ontologies, but also on the context in which resources are found and used. This contextual information could provide for more accurate mechanisms for learning resource discovery and use. Important Scientific Research and Open Questions Research on semantic technologies in learning has been developing in several directions. A non-exhaustive list of such directions and open research questions includes: ● Collaborative knowledge representation and main- tenance in learning environments S 3031 ● Supporting personal and group knowledge con● ● ● ● ● ● ● struction with semantic technologies Establishing the underpinning pedagogy of semantic applications or introducing pedagogy in semantic applications Knowledge extraction on resources related to learning Transition from taxonomies and hierarchies to more expressive ontologies for learning Semantic applications for critical thinking and argumentation Exploring the potential of semantic technologies for exploratory learning and problem-based learning Investigating the potential of sharing and combining linked data inside or across educational institutions Semantic technologies to capture and enhance informal learning processes There are systems that can support personal or collaborative knowledge construction, which are often Wiki-based or Topic-map based. In many cases, the constructed knowledge is not available in machine processable formats or formats that are appropriate for integration with other relevant applications. This opens siginificant questions on the feasibility, scalability, and efficiency of semantic technology based approaches to learning resource authoring and to data interoperability and integration for learning systems. In addition, the potential of semantic technologies to support pedagogy in technology-enhanced learning requires further research. Semantic applications seem promising in supporting critical thinking and argumentation given the availability of relevant resources and applications. Applications that combine resources described using lightweight vocabularies on a large scale, across educational institutions and organizations, could potentially support novel processes for formal, informal, exploratory, and problem-based learning.

Semantic technologies in learning and teaching (SemTech) – JISC Report. London, England: Joint Information Systems committee (JISC). http://www.jisc.ac.uk/media/documents/projects/semtech-report.pdf The term “semiotics” can be traced back to the ancient Greek semeiοn (semeion), which means “sign” or “index.” As the theory of signs, semiotics investigates the intentional use of signs to represent something – for instance using a red light to represent (and communicate) danger. Semiotics as a discipline is concerned with the use of all forms of signs: from human gestures to different forms of animal communication and information processes within living cells or molecules. The relevance of semiotics for the study of learning results from the fact that virtually all learning takes place through text and speech and presupposes the use of linguistic signs and symbols. In addition, in many learning situations, picture-like signs are also used for representation and communication purposes. Accordingly, semioses (i.e., sign processes) are considered to be an important ingredient for cognition, learning, and teaching. Theoretical Background " Semantic Web and Learning ▶ Semantic Technologies and Learning Semiotics and Learning NORBERT M. SEEL Department of Education, University of Freiburg, Freiburg, Germany Synonyms Sign systems; Symbolism Definition Cognitive psychology and conceptions of cognitive learning argue that human learning and thinking necessitate computational processes on symbolic notations of mental representations and the use of signs and sign systems. Semiotics is the study of signs as elements of representation and communication, and therefore cognitive learning and semiotics are closely related with each other. “Let me tell you first what I and my friends thought the [cognitive] revolution was about there in the late 1950s . . . It focused upon the symbolic activities that human beings employed in constructing and in making sense not only of the world, but of themselves” (Bruner 1990, p. 2). Accordingly, cognitive and educational psychologists, such as Aebli, Ausubel, Salomon, and many others, have recognized the central importance of sign processes (semioses) for human learning and thinking. It has been argued that learning and thinking depends not only on the availability of domain-specific knowledge and cognitive skills but also on individuals’ semiotic competence in using specific sign systems for representational purposes (Seel and Winn 1997). This argumentation corresponds to the basic assumption in cognitive psychology that thinking is a process of symbol manipulation which enables learners to form and express subjective experiences, ideas, thoughts, and feelings. Accordingly, the question of how knowledge about facts, events, actions, and plans is represented by means of signs and sign systems has been recognized as central to the construction of theories of human cognition. However, the idea that cognition presupposes the capacity to represent knowledge by means of signs and rules for manipulating these signs has a longer history Semiotics and Learning than cognitive psychology. It can be traced back to the ancient Stoics and the Indian Nyaya Sutras (approximately 200 BC) and can also be found in the work of John of Saint Thomas, Locke, Leibniz, Peirce, Morris, and others who were concerned with semiotics and all forms of signs that can serve communicational and representational purposes. The basic understanding of the use of signs has been described by Goodman (1968), who explains that the introduction and use of a sign is always a definition by an individual who intentionally takes something as a specific sign in order to represent something else. More specifically, Goodman argues that (1) anything can be a representation of something else; (2) it is the cognitive system that takes something as a representation of something else; and (3) it follows from (1) and (2) that a representation is always what a cognitive system defines or takes intentionally as a representation. Nothing can be a representation without the intentional activity of representing. Several decades earlier, Külpe (1923) and Cassirer (1929) had developed similar conceptions by pointing out that a world of self-constructed signs is faced with so-called objective reality. As ways of worldmaking (Goodman 1968), semioses presuppose representational means as signs that refer to the objects to be represented. Traditionally, semiotics differentiates between the intentional use of a sign as an index, icon, and/or symbol, and it usually locates the prototype of a sign in verbal language. This basic distinction has been adapted to some extent in the area of cognitive psychology. For instance, Bruner distinguishes between enactive, iconic, and symbolic forms of representation. A good example for enactive representation is dancing, which may serve as a nonverbal language for imagining and learning. Anderson (1983) distinguishes between temporal strings, spatial images, and propositions; and Johnson-Laird (1983) makes a distinction between images, mental models, and propositions. Besides some differences in detail, there is agreement that there are picture-like (“images”) and language-like (propositions) forms of representation. Some decades earlier, Piaget (1959) introduced a particular epistemological view on semiotic functions he considered necessary for cognition since they provide the means of mentally representing objects and structures in the real and imagined world. According to Piaget, thinking presupposes that cognitive operations S follow through on their commitment to perceptions and concrete actions. They are executed mentally on the basis of gesticulatory, pictorial, linguistic, or other (for instance symbolic) signs that function as media of thinking. This requires the functional incorporation of communication codes into the space of mental representations. This internalization, or adaptation of the external for internal use (Salomon 1979), involves abstracting and transposing imitative actions into so-called semiotic functions comprising the totality of denotation functions that are separated from the content of perception and recognition of objects. Semiotic functions include all imaginative and depictive actions of the human mind. They are not components of the thinking process itself but rather aids for representing knowledge about the world. Naturally, the emergence of semiotic functions follows a developmental sequence. At the beginning of this sequence are imitative social behaviors and at the end are linguistic signs. Accordingly, the development of semiotic functions starts with imitation and symbolic play, followed by delayed imitation (i.e., imitation in absence of the model),“drawings, painting, modeling, and the use of internal images, and culminating in verbal language and the use of linguistic signs” (Piaget 1959). The role of verbal language as a thinking tool has been discussed for a long time in philosophy and psychology. Generally, it can be argued that thoughts can be expressed through language and that internal speech supports thinking. However, an individual who uses language and linguistic signs for knowledge representation must be able to store and retrieve these signs just as knowledge. Therefore, it is possible to differentiate between two stages of language use: In the first, language is used to communicate automatically, whereas the second requires that the individual knows explicitly how to operate with language in order to represent and communicate knowledge. Piaget’s ontogenetic view on semiotic functions presupposes the internalization as well as the mental manipulation of signs. Basically, internalization has two aspects, namely: (a) a figurative aspect based upon the continuous transposition of imitation activities into picture-like or language-like signs, and (b) an interpretative aspect which assigns meanings to signs. On the whole, the process of internalization constitutes the fundamental basis for mental representations by bringing about the transition from concrete 3033 S 3034 S Semiotics and Learning experiences to imagination. Representational codes and semiotic functions evolve in accordance with the individuals’ capability to differentiate between a sign and its denotation, between meaning and phenomenon, between linguistic expressions and their content. Evidently, the use of signs and symbols follows the gradual developmental of intellectual capacities. This can be illustrated by ▶ The Harvard Project Zero: Following a period of mundane symbol mastery in infancy, young children rapidly attain initial competence in dealing with a broad range of sign systems in their culture (e.g., language, gestures, pictures, numbers, and music) mediated by everyday life experiences. By school age, the major task is the mastery of notations (for instance, in mathematics) that entail learning features of reduction, systematicity, and legibility. In consequence, there are authors who aim to create multiple semiotic worlds in the classroom (Hicks 1995) by focusing on the use of different signs and symbols for representation and communication purposes. Important Scientific Research and Open Questions In the course of the past four decades, semiotics has established itself as an independent scientific discipline that can be divided into a philosophical theory of communication concerned with the creation of sign processes for the acquisition and mediation of knowledge and an information theory which considers semioses as natural processes and thus as natural objects of empirical investigation. However, from the point of view of philosophical semiotics the principal decision to follow an empirical approach is subordinate to the traditional reflective approach. The role of sign processes in mental representation was a central issue of the so-called imagery debate of the 1980s in cognitive psychology. The controversy had to do with the question as to whether mental representations and computation are only based on the use of abstract symbols or also on picture-like images. The major result of the imagery debate was that there is now general agreement among cognitive psychologists on the point that humans primarily (but not exclusively) use picture-like and language-like signs for representation and communication purposes. This theoretical conception has been elucidated recently in Mayer’s framework of cognitive learning as well as in the cognitive load theory. Parallel to the imagery debate, educational psychologists were concerned with the idea of internalization and transposition of communication codes for representation purposes. These researchers focused especially on the interaction between media, cognition, and learning (Salomon 1979). The central idea of this research (for an overview see: Seel and Winn 1997) was that individuals prefer to represent information mentally in the same modality which was originally used to communicate it to them. In consequence, it should be possible to influence the acquisition and application of different sign systems for representing knowledge in dependence on specific experiences by using signs in communication situations with specific characteristics. This argumentation culminated in Salomon’s (1979) supplantation hypothesis, which assumes that the sign systems and coding elements of communication may affect information processing and related semioses by way of two basic mechanisms. Either the sign systems used in communication activate preexisting mental skills and cultivate skill mastery through exercise, or they overtly supplant mental skills into which the signs and codes of communication (such as pictorial and linguistic signs) are then functionally incorporated through modeling. Accordingly, the signs used by delivery systems and media can, once internalized, be used as tools for thought. Another important line of research on semioses followed the assumption that individuals acquire semiotic competence in the course of school learning. Indeed, from the perspective of semiotics, instruction does not aim only at the acquisition of knowledge and cognitive skills but rather also involves the functional incorporation of signs and symbols for representation and communication purposes. This raises the question as to whether and how we can facilitate semioses through instruction. Indeed, an important goal or side effect of school learning consists in the mediation of particular symbol systems. “Children progress through a regular sequence of stages in their transition from dependence on concrete material to the ability to apprehend the meaning of abstract propositions presented symbolically . . . At this stage of development, therefore, properly arranged reception of symbolic material is highly meaningful” (Ausubel and Robinson 1969, p. 109). This can be illustrated by learning in the classroom in specific disciplines, such as mathematics, physics, chemistry, biology, and so on, where students Semiotics and Learning have to learn certain symbolic systems and models that are often radically different from their everyday experiences. Greeno (1989) provided some examples to demonstrate that, unsurprisingly, individuals in fact do not use the symbol systems taught in schools when they have to solve everyday problems. This corresponds to Bruner’s (1968) assumption that individuals can use alternative sign systems for knowledge representation. The use of a particular sign system for representing and communicating knowledge is primarily a matter of adaptation to a particular case – but not in the classroom where the particular demands of the various disciplines constrain the use of sign systems. In the area of subject matter learning, cognitive processes are traditionally separated from the manipulation of symbolizations or inscriptions, as the example of mathematical learning illustrates (Meira 1995). Recent research in the field of mathematics learning considers mathematizing as a form of modeling that usually involves using specialized languages, symbols, graphs, pictures, concrete materials, and other notational systems to develop mathematical descriptions and explanations that obviously make great demands on learners’ representational capabilities (Lesh and Doerr 2000). Similarly, research in the area of biology and biochemistry learning shows that experts can be defined especially well by the specialized symbol systems they use to represent and communicate domainspecific knowledge (Kindfield 1999). On the whole, research on semioses within the realm of subject matter learning is still in its infancy. This holds also true with regard to the interplay between semiotics, cognitive theory, and learning in virtual environments as investigated initially by Winn et al. (1999).

Examples from everyday life include adaptation to the visual distortions caused by prescription glasses, to the unfamiliar driving characteristics of a rental car, and to the changes of limb length and muscle force during maturation. Adaptation can be understood as a form of motor learning, accomplished by the modification of existing behavior rather than by the acquisition of new behavior. It is achieved by evaluating sensory information about performance errors, and using it to induce changes at two hierarchical levels: a lower level recalibration of sensorimotor pathways, and higher level adjustments of motor strategies. The Latin word “adaptare” means to fit together, and is derived from the Greek word “aptos” = appropriate. Theoretical Background Sensitization ▶ Perceptual Learning In 1867, Helmholtz was the first to report that subjects wearing wedge prisms before their eyes will initially misreach for visual targets, but will overcome their errors with practice. This phenomenon spurred Sensorimotor Adaptation vigorous research by experimental psychologists in the 1950s and 1960s, and became popular again since the 1990s as an easily observable manifestation of neuronal plasticity. It was found that adaptation is not limited to prismatic displacements and other visual distortions; rather, subjects adapted as well to acoustic, tactile, ▶ proprioceptive, and mechanical (i.e., force field) distortions. Furthermore, adaptation was found for different types of motor response, such as pointing, grasping, and tracking movements of the arm, saccadic eye movements, walking, and balancing. In modern research, adaptation is typically evaluated by asking subjects to point at visual targets while visual feedback of their hand is distorted. Readers can easily replicate this paradigm by trying to point at objects on a computer screen with a computer mouse that is rotated 90 clockwise: at first, they will dramatically misdirect the mouse pointer, but their performance will gradually improve within about 20 min. Adaptive improvement under a distortion does not follow a simple exponential function, but rather is characterized by at least three time constants, in the order of seconds, minutes, and weeks. These time constants reflect distinct mechanisms, with different functional properties. Once the improvement is completed, it is possible to observe various aftereffects: generalization of adaptive behavior to new locations in the workspace and to new movement types (e.g., from pointing to tracking), transfer of adaptation to another limb or to a new distortion, persistence of adaptive behavior even if it is no longer adequate since the distortion was removed, retention of the adaptive change such that it emerges again when the same distortion is reintroduced up to 1 year later, and metalearning of the ability to adapt (e.g., easier adaptation to left-right reversal following an adaptation to up-down reversal). Adaptive improvement is achieved both by a recalibration of sensorimotor pathways, and by strategic adjustments such as postural changes, associative learning of stimulus–response pairs, and cognitive reinterpretations of sensory feedback. In contrast, aftereffects are due to recalibration alone, since strategies are effortful, situation-specific, and short-lived, and therefore quickly dissipate when no longer needed. This differential role of strategies is reflected by the differential effect of several factors on adaptive improvement versus aftereffects. Thus, old age and S 3037 poor cognition were found to degrade adaptive improvement but not aftereffects, while a happy mood facilitated improvement but not aftereffects; this indicates that emotions, cognitions, and aging are more closely related to strategies than to recalibration. In contrast, dopamine depletion in Parkinson’s disease degraded improvement and aftereffects, which suggests that the dopaminergic system is involved in recalibration. The most popular distortion in adaptation research is a rotation of visual feedback about the starting point. Adaptation to this rotation is achieved by a gradual rotation of an internal reference frame from its original orientation through intermediate angles up to the required value. In consequence, adaptation to a given angle of rotation facilitates the subsequent adaptation to a larger rotation, and hinders the subsequent adaptation to an opposite rotation. The internal reference frame cannot be rotated by more than 90 ; adaptation to larger distortions is achieved by an abrupt axis inversion (which corresponds to a 180 rotation), followed by a gradual “backward” rotation of the internal reference frame. Important Scientific Research and Open Questions What type of error is used to drive adaptation? Error information about an ongoing movement could be derived from visual and from proprioceptive signals. It has been shown that either modality can drive adaptation, but if both are available, proprioception is suppressed unless it provides relevant information not available in the visual system. Other work documented that adaptive changes are based on the discrepancy between intended and observed movements (i.e., sensory prediction errors), rather than between observed movements and targets (i.e., target errors). Since sensory prediction errors are processed mainly in the cerebellum, it is not surprising that adaptation depends critically on the integrity of that brain structure. However, it remains unclear whether the cerebellum passes the error information on to adaptive mechanisms located elsewhere, or rather is itself the site of adaptive change. Since the adaptation deficits of cerebellar patients are fully explainable by their motor control deficits, the cerebellum seems not seem to possess separate mechanisms devoted only to adaptation and not to motor control. S 3038 S Sensorimotor Adaptation Where in the brain is adaptation located? Most neuroimaging studies attempted to capture adaptationrelated activation as the difference between activations in an adaptation task and in a distortion-free control task, and found that differential activity to be widely scattered throughout the brain. However, the adaptation task differed from the control task not only by the presence of adaptation but also by the presence of movement errors, and the reported activity therefore included error-related processes such as surprise, attention focusing, and corrective eye and arm movements. Studies using more adequate control tasks yielded much less activation, mainly in the inferior parietal cortex, the dorsolateral premotor cortex, and a small area in the superior cerebellum, which is known to be connected with the other two. Is adaptation based on one common, or on multiple, task-specific mechanisms? Adaptation achieved in a given sensorimotor task was found to transfer to a different sensory modalitiy, movement type, end-effector (e.g., arm to arm, and arm to eyes), and distortion (e.g., position-dependent to velocity-dependent, and visual to mechanical). This indicates that different sensorimotor tasks can access a common adaptive mechanism. However, the magnitude of transfer was often moderate or small, which suggests that access to the common mechanism is limited. From this, it has been concluded that adaptation is based neither on one common nor on multiple task-specific, but rather on multiple overlapping mechanisms. This work is relevant for rehabilitation, which builds upon a transfer from therapeutic interventions to real life. Can we adapt to several distortions at the same time? We can adapt to two distortions if each is associated with a different arm, arm posture, target location, gaze direction, or background color. This has been taken as evidence that adaptation is localized in multiple modules, which the sensorimotor systems can access depending on contextual cues. It remains open how many of those modules exist, and thus, to how many distortions we can concurrently adapt. What cognitive functions contribute at which time during adaptation? This question can be answered by a dual-task approach, with subjects adapting while concurrently engaging in a cognition-demanding task: interference between both tasks could be taken as evidence that they compete for a common pool of resources. An alternative approach is to correlate each subject’s adaptive progress with their cognitive performance scores established in a separate session. Both approaches have been rarely used in literature, but preliminary evidence suggests that the cognitive demand changes during adaptation, quantitatively and qualitatively. Do astronauts adapt to weightlessness? The absence of gravity changes the functioning of several sensory modalities, and modifies the behavioral outcome of motor commands; it thus represents a combined sensory and motor distortion, to which astronauts must adapt. Indeed, movements executed in weightlessness are slower, less accurate, and/or cognitively more demanding than on Earth, and these deficits gradually diminish with time. Gross motor tasks such as postural responses normalize within days, while fine motor tasks such as handwriting are not fully compensated even after several months of spaceflight. Early adaptation of fine motor performance draws on cognitive resources related to sensory functions, while late adaptation requires predominantly resources related to movement planning. The pronounced resource-dependence, as well as the scarcity of aftereffects, suggests that much of the adaptation to weightlessness is achieved by strategic adjustments rather than by recalibration.

Sensorimotor Schema Sensorimotor Learning ▶ Anticipatory Learning ▶ Learning to Sing Like a Bird: Computational Developmental Mimicry ▶ Song Learning and Sleep Sensorimotor Schema FRANK GUERIN Department of Computing Science, University of Aberdeen, Aberdeen, Scotland, UK Synonyms Enactive or action schemas; Infant habitual action Definition Within constructivist theories, the sensorimotor schema is held to be the principal unit of knowledge in use during infancy. A sensorimotor schema is a psychological construct which gathers together the perceptions and associated actions involved in the performance of one of the habitual behaviors in the infant’s repertoire. The schema represents knowledge generalized from all the experiences of that behavior. It includes knowledge about the context in which the behavior was performed as well as expectations about the effects. Sensorimotor schemas are central to Jean Piaget’s explanation of infant development. Theoretical Background The development of the psychological construct known as the sensorimotor schema has its origins primarily in the work of Jean Piaget and, in particular, in his books on sensorimotor development (Piaget 1936, 1937). Sensorimotor schemas are a special case of the more general notion of schemas. Like schemas they are knowledge structures which represent the generic knowledge abstracted from a number of experiences in a similar situation. Sensorimotor schemas are simply those schemas which are in use during the sensorimotor period (from birth to roughly the end of the second year). A typical example of a sensorimotor schema is the schema of shaking a rattle. This schema gathers S together the visual and tactile perceptions of the rattle, as well as the motor actions involved in the shaking, and the expectation of visual and auditory perceptions during the execution of the action. Because it is generic, the same schema could be said to operate in the infant’s interactions with a class of objects which are broadly similar to the rattle, and where the infant’s action is broadly similar. If the infant is presented with a new object, and the infant seems to treat it like the rattle, shaking it in a similar way, then Piaget would say this new object had been assimilated to the schema of the rattle. If the rattle-schema is adjusted to account for slight differences in this new object, then Piaget would say the rattle-schema had accommodated to the new object. If the accommodation is significant, then Piaget would say that the schema had been differentiated to produce a new schema appropriate to the new situation. In other situations, it may be that two independent schemas are found to be closely correlated and become combined as a new (higher-level) schema. In this way, Piaget describes the whole of infant development from the perspective of the operation of sensorimotor schemas. In comparison with the schemas in use in adults, sensorimotor schemas tend to be less abstract and more directly tied to the actions, objects, and contexts in the infant’s experiences. Nevertheless, there are major differences in the types of schemas in use at the start of the sensorimotor period and at its end, with a clear progression toward more abstract and higher-level schemas. Piaget defined six sequential stages during sensorimotor development (Piaget 1936), with a qualitative difference between the sensorimotor schemas in use in each stage. The first of these stages is the reflex stage (roughly the first month), where the reflex actions such as sucking and grasping, and papillary and palpebral reactions to light are exercised. Each of these actions is associated with its own global schema which generalizes from experiences, where the action happens, and gradually learns to recognize the situations where the action is triggered, and the expectation of what sensory impressions arise while the action is in progress. Furthermore, different modes of operation become recognized, for example, the difference between sucking the nipple for feeding or sucking the fingers. The second stage (roughly from 1 to 4 months) begins with schemas which arise from the fortuitous discovery of the results of actions on the infant’s own 3039 S 3040 S Sensorimotor Schema body, for example, the schema of sucking the thumb. Piaget identifies these schemas with what J. M. Baldwin has called the circular reactions. In this stage, schemas are also formed which integrate different modalities, for example, auditory, tactile, and visual. By the end of this stage, a schema for reaching for, and grasping, seen objects has been formed. During the third stage (roughly from 4 to 8 months), it is again a case of repeating results fortuitously discovered, but these schemas are now of a higher order because they act on objects in the environment. Piaget calls these the secondary circular reactions. A typical example of a schema discovered at this stage is that of pulling a string to shake a rattle. Note that the infant at this stage is incapable of understanding the connection between the string and rattle, and will not be capable of discriminating, in advance, situations where the string is connected or not connected. This schema is a global ensemble, incorporating parts whose connection is not fully understood. During this stage, there is a rapid growth in the number of schemas in the infant’s repertoire as new schemas are differentiated from previous ones in order to repeat interesting discoveries. Example actions include squeezing, shaking, striking, scraping, rubbing, and pulling. During the fourth stage (roughly from 8 to 12 months), intentional means-end sequences of actions are performed. For example, the infant will intentionally displace an obstacle in order to retrieve a desirable object which is visible behind it. In this type of situation, two distinct sensorimotor schemas can be distinguished; one for the means action, which displaces the obstacle, and one for the end, which is to grab the desired object. The schema of the end is able to subordinate the means schema, and to direct its operation. This implies that the sensorimotor schemas must now incorporate relatively advanced knowledge of the world because the effect of an action on an object is understood, and also on the relationships between objects (e.g., the relationship “in front”). In contrast to the previous stage, at this stage, the schemas can be combined in new situations and are not confined to the situations where the combination was discovered fortuitously. For this reason, Piaget refers to these as mobile schemas. During the fifth stage (roughly from 12 to 18 months), schemas become ▶ experimental; they are not only repeated, but are intentionally varied so that the relationships between initial conditions and effects can be studied. Piaget calls these schemas tertiary circular reactions. This new experimental ability can now be employed to generate new means schemas when the infant’s existing repertoire does not happen to have the appropriate means schema. An example of this is the effort to retrieve an out-of-reach object with a stick; even if the infant does not have schemas for performing the appropriate actions to displace the object, the required schemas can be discovered through experimental groping. The sixth stage (roughly from 18 to 24 months) could be said to not properly belong to the sensorimotor period because there is significant evidence of internal representation of objects, actions, and effects. This gives rise to covert planning, where rather than groping in the world, the infant carries out the necessary experimentation mentally and then exhibits a complete correct sequence of actions. This has been achieved by internalization of the sensorimotor schemas acquired previously. Through all this progression, there is a gradual increase in the abstractness and objectiveness of the sensorimotor schemas; while the earliest schemas capture a very subjective knowledge locked in particular contexts, the later schemas have abstracted away from these contexts and capture knowledge about relationships between objects and actions in the world. In this development, schemas are a tool for learning because their effort to repeat and assimilate events leads them to generalize and gradually embody more abstract information about the world. The term “sensorimotor schema” is not widely used in contemporary psychological research. Piaget’s theory paints a picture of a very close coupling between the development of perceptual competences and action competences, and even representation and reasoning, with each being built up in tandem by the same process. For this reason, the idea of a sensorimotor schema which combined all elements made sense as the unit of knowledge. A classic example is in the case of the means-end action of retrieving a hidden obstacle. Piaget held that it was through experiences with acting on objects in relationships such as “in front” that the perceptual competence and representational competence to understand about hidden objects was constructed. Later research has suggested that perceptual and representational competence may be more Sensory Curiosity independent from action competence (Bremner 1994), and that in most cases perceptual competence precedes action competence but in some cases the reverse may be true (Kellman and Arterberry 1998). Although a consensus has not yet been reached on many details, the general picture emerging is considerably more complex than Piaget’s account, and the sensorimotor schema may be at too coarse a level for its proper description. Important Scientific Research and Open Questions Since Piaget’s early work on infancy new experimental methods have been developed to probe infants’ knowledge of the world, most notably the infant habituation method, and the violation of expectation paradigm. This measures infants’ looking times to determine if the event displayed to them violates their expectations. This method has been used to determine such things as knowledge that objects continue to exist while occluded. This work has uncovered a curious gap between the advanced knowledge which infants seem to demonstrate by looking and the relatively impoverished knowledge that seems to be available to them when they are required to act. There is considerable controversy about many of these results, and especially their interpretation, with some scientists contradicting them outright (Cohen and Cashon 2003). Neuroscientific evidence suggests that there are in fact two parallel processing streams for objects; the ventral or “what” stream, and the dorsal or “action” stream. The fact that there might be multiple partial object representations (Mareschal et al. 2007), independent of a particular behavior, suggests the need for a much more fine grained unit of organization than Piaget’s sensorimotor schema; although there must be cells integrating this sensory and motor information, these cells must be integrating relatively sophisticated fragments, rather than building up the knowledge from scratch as in Piaget’s theory. Within Artificial Intelligence, there have been some efforts to computationally model sensorimotor schemas; this requires a representation to capture schema knowledge. There is a consensus in a number of works that a schema should be a three-part structure with an initial state description, and action, and a predicted resulting state description. There are also S 3041 ongoing efforts to define algorithms which can exhibit cognitive development by building higher-level schemas out of lower-level ones (e.g., Chaput 2004). Many questions about sensorimotor schemas remain to be answered. For example, is the sensorimotor schema really a useful concept to serve as a generic knowledge structure, or is it maybe an approximation for great diversity of different things which only seem to share similar features from a “zoomed out” view but may turn out to be quite different on closer inspection. Similarly, it is not known if sensorimotor schemas really do share a common structure with later more abstract adult schemas (as suggested by Piaget) and if they are reusing the same machinery in the brain, or if on closer inspection they may be quite different.

Sensory Curiosity ▶ Curiosity and Exploration S 3042 S Sensory Learning Sensory Learning ▶ Visual Perceptual Learning Sensory Learning Styles A categorization of learning styles according to the sensory modalities that are applied for learning information. Generally, four modalities are distinguished: Visual, Aural (sound), Read/write, and Kinesthetic (touch). Learners usually have a preference for a certain sensory style of learning. Sensory Memory ZHONG-LIN LU Departments of Psychology, University of Southern California, Los Angeles, CA, USA Synonyms Sensory registers Definition Stimulation of human sense organs is initially represented in sensory memory for a brief period by a literal, labile, and modality-specific neural copy. The term iconic memory stands for the initial representation of visual stimuli, and echoic memory is its counterpart for auditory stimulation (Neisser 1967). Sensory memory is often contrasted with short-term memory and working memory which are assumed to be less modality specific, and all of these are distinct from long-term memory. In functional terms, sensory memory is comparable to a register in a computer. In a human, if you want to know what the last sensory input was, you examine the sensory register. The prevailing view of human memory systems is that there are one or more modality-specific sensory registers in each sensory modality, plus a register or registers for short-term and/or working memory, plus functionally distinct long-term memory systems for episodic, semantic, procedural, and perhaps others form of longterm memory. Theoretical Background Visual sensory memory, i.e., iconic memory, was first demonstrated by George Sperling using the partialreport paradigm (Sperling 1960): After a brief presentation of a 3  3 or 3  4 array of letters, observers often can report all the letters in any cued row if the cue occurs immediately after the visual presentation (“partial-report”), even though they can only report four to five letters when asked to recall all the items in the display (“whole-report”). Because all rows are cued with equal probability, reporting all the items in a randomly cued row implies that observer has access to all the items in the array at the termination of the display. The partial-report superiority effect – performance advantage of partial-report over wholereport – suggests that there exists a fast-decaying iconic memory that can initially hold at least 9–12 items. Numerous studies have established that iconic memory has a large capacity, decays rapidly, and is destroyed by post-stimulus masking (Coltheart 1980; Gegenfurtner and Sperling 1993; Neisser 1967; Sperling 1960). The duration of iconic memory has been estimated to be about 300–500 ms for young adult observers. Auditory sensory memory, also called “echoic memory” (Neisser 1967), is essential for integrating acoustic information presented sequentially over an appreciable period of time (Crowder 1976; Glanzer and Cunitz 1966; Treisman 1964; Wickelgren 1969). Psychophysical experiments suggest that echoic memory resides at a central rather than a peripheral site (Massaro 1975). Electrophysiological investigations of auditory memory functions in animals provide evidence that similar short-term memory functions are served by sensory areas of cerebral cortex (Weinberger et al. 1990). In biological sensory processing, there is a considerable amount of memory – perhaps more aptly called retention – that is inherent in the processing itself. So, in a broad sense, sensory memory exists and may differ for different stimuli in every stage of sensory processing. For example, visual sensory memory exists in the receptors and bipolar cells of the retina as an afterimage. These cells do not constitute a register in the usual meaning of the word, but they can retain a representation of the input image long after it has been removed. The afterimage is a negative of the original stimulus that is perceived upon subsequent stimulation. The original stimulus can itself persist in the retina as “persistence of sensation.” Sensory Memory A complete understanding of a sensory memory system requires specification of (1) its brain location, (2) the time constant for which it retains information, and (3) the format (or encoding) of the information it retains. The magnetoencephalography (MEG) habituation paradigm developed by Lu, Williamson, and Kaufman (Lu et al. 1992a) offers a means to specify the first two components of a sensory memory (location and time constant) and perhaps the third (encoding) as well. In this paradigm, the same stimulus is presented repetitively with different repetition rates. The recovery of the MEG response with increasing inter-stimulus interval (ISI) serves as a measure of the decay of the initial activation. In its first application, Lu et al. (1992a) used auditory stimulation with various repetition rates to characterize the temporal dynamics of neural activation in the primary and secondary auditory cortices of human observers in terms of simple exponential decay functions. They later found that the lifetime of a cortical activation trace in primary auditory cortex predicts the lifetimes of behaviorally determined auditory sensory memory of the loudness of a tone for each individual subject (Lu et al. 1992b). Using the same paradigm with flickering checkerboard stimuli, Uusitalo, Williamson, and Seppa (Uusitalo et al. 1996) were able to detect 10 brain locations with different recovery time constants in the visual system. Each one of these brain locations represents a process with an inherent retention time, a process that could become a component of the overall retention time observed in a psychophysical sensory memory experiment. Important Scientific Research and Open Questions Vision and audition each have several levels of sensory memory, and constructing experiments to selectively measure one or another of these memories has been an elusive goal. There have been many attempts in the literature to distinguish different forms of visual sensory memory (for review, see Coltheart 1980, Long 1980). One well-recognized distinction is between eye-specific visual persistence and non-eye-specific iconic memory. Many have debated interpretations of results from information-based assessments (e.g., the partial-report procedure) and some more direct sensory measures of visual sensory memory. Coltheart (1980) concluded that the partial-report procedure mostly reflects retinal nonspecific iconic memory S 3043 (but see Massaro and Loftus 1996). Beyond visual sensory (iconic) and visual short-term memory, deriving the taxonomy of visual memory systems has not been possible by means of psychophysical tasks alone. The taxonomy of auditory sensory memory systems is probably even more complicated because auditory signals are subjected to much more complicated processing prior to reaching auditory temporal cortex area A1 than are visual signals before reaching occipital cortex area V1. Cowan’s reviews conclude that there are at least two forms of auditory sensory memory: a very shortlived memory such as the memory for tonal loudness described above and a second auditory sensory memory with a duration on the order of seconds (Cowan 1995). Indeed, it is not obvious that the next-higher auditory memory can be characterized by a time constant in seconds. It might be a limited capacity memory based on retroactive interference – new inputs push older material out of memory. In the absence of new auditory input (i.e., silence), periods of silence might themselves be recorded as memory events. This is a much more complex process than simple, exponential passive decay with time, although it may be difficult to distinguish from passive decay when new stimuli arrive at a constant rate.

Offline learning; Procedural memory consolidation; Skill enhancement Definition Following practice, a new skill memory continues to be processed offline during a period of consolidation. Consolidation stabilizes a memory, making it more Sequence Skill Consolidation in Normal Aging resistant to decay from the passage of time, competing information, or physical changes to the nervous system. For some types of skills, such as the ability to produce a sequential pattern of movements, consolidation can be expressed as an improvement in skill that develops between practice sessions, a phenomenon that has been called “offline learning.” Following an offline interval, usually at least several hours in duration, an individual is able to increase the speed, accuracy, or efficiency in which the learned sequence is executed compared to a novel or random pattern of movements. Deficits in consolidation therefore undermine the benefits of practice and training. Recent evidence has suggested that offline learning is impaired in normal aging. With an aging population and technological advances that constantly introduce new skills, understanding the changes in sequence skill consolidation as a result of normal aging has emerged as an important topic of research. Possible mechanisms accounting for impaired consolidation in aging include disruption of sleep, changes in local synaptic plasticity, as well as alterations of interhemispheric interactions and other shifts in neural network dynamics with aging. Theoretical Background Sequence learning refers to knowledge about the underlying predictive structure between temporally ordered or contingent events (for a review, see Keele et al. 2003). Everyday activities such as writing, cooking, typing, and driving can unfold relatively automatically without attention to the individual movements that make up these actions. The neural substrate for sequential knowledge depends on multiple factors, such as the information format (i.e., sensory or motor codes) and reference frames (i.e., egocentric or allocentric coordinates) that define the individual elements of a sequence, as well as the underlying predictive structure in which downstream elements are predicted by preceding elements. For example, patients with medial temporal lobe pathology demonstrate normal sequential learning when there is a first-order predictive structure to the sequence (each element is predicted with a certain probability by the immediately preceding element) but show some deficits with higher-order associations (each element is predicted by combinations of preceding elements). Recent evidence suggests that there are multiple mechanisms involved in offline learning depending S on the underlying nature of the sequential information and the corresponding neural networks representing that information (Robertson and Cohen 2006). For example, electrophysiological events unique to sleep may promote strengthening of neural connections within a memory network for some types of skills. Sleep may be particularly important for offline learning in sequential tasks that depend on the hippocampus (Spencer et al. 2007). Even within the same task, multiple components of a sequential skill may be acquired in parallel and yet undergo consolidation preferentially in distinct physiological states. For example, after learning a motor sequence in response to visual cues in a finger tapping task, known as the serial reaction time task (SRTT), offline learning for the spatial layout of targets (allocentric coordinates) preferentially occurs over a night with sleep, and offline learning for the specific series of muscle contractions (egocentric coordinates) preferentially occurs over the waking day (reviewed in Robertson and Cohen 2006). Sleep undergoes characteristic changes with the aging process. Alterations of sleep may represent one mechanism causing sequence skill consolidation to decline with normal aging. In healthy elderly individuals, there is a decline in nightly total sleep time, an increase in the rate of arousal, reduced amount of slow wave activity (EEG oscillations in the 0.5–4.5 Hz frequency bands and a marker for sleep depth),and reduced sleep spindles. Slow wave sleep in particular has been implicated in the neuronal reactivation or replay of neuronal firing patterns activated during recent wakefulness, a mechanism in which sleep may promote use-dependent synaptic plasticity and memory enhancement. In addition, skill learning increases subsequent slow wave sleep locally in cortical regions involved in the skill memory network. The induced slow wave changes are postulated to contribute to synaptic homeostasis, tuning the connectivity within a skill memory network and improving the signal-tonoise ratio. Sleep spindles have also been implicated in processes of memory consolidation. Therefore, the changes in sleep with aging would generally predict impaired memory consolidation. However, there are multiple offline learning mechanisms depending on the anatomical networks involved, and some offline mechanisms do not require sleep, so it remains possible that offline learning could be preserved, at least for some tasks, during the aging process. 3045 S 3046 S Sequence Skill Consolidation in Normal Aging Long-term potentiation (LTP) and long-term depression (LTD) represent core models of local synaptic plasticity and are widely believed to be key molecular correlates of memory processes. LTP/LTD reflect a cascade of molecular events that unfold over time following an initial stimulation protocol, ultimately leading to more or less effective synaptic communication within elements of a neural circuit. Late phases of LTP/LTD are protein synthesis dependent and act on the scale of hours, similar to the time course of offline learning. While it remains unclear whether LTP/LTD or specific phases of LTP/LTD coincide with behavioral observations of memory consolidation, these models make it clear that some mechanisms of synaptic plasticity are impaired with aging. The decline in synaptic plasticity with age is potentially related to a decline in positive modulators or an increase in negative modulators (Lynch et al. 2006). One negative modulator of LTP is adenosine, a product of neuronal energy metabolism, whose concentrations increase in the cerebral extracellular space with increased wakefulness and decline with sleep. Adenosine concentration increases in aging might be possibly explained, at least in part, by the changes in sleep physiology mentioned above. Interestingly, in early aging, there appears to be a regionally specific decline in the capacity to induce LTP/LTD. Such regional specificity for changes in plasticity would also suggest that offline learning might be impaired for some types of skills and relatively preserved for others during the aging process. In addition to changes in synaptic and local plasticity, aging is associated with changes in activity along distributed bihemispheric brain networks. Functional neuroimaging studies have shown that older adults, even when task difficulty is controlled for, tend to over-recruit brain regions during perceptual, motor, and cognitive tasks. Older individuals also show a loss in functional specialization and hemispheric lateralization. These findings suggests a shift in functional brain network dynamics that some have argued might represent an adaptive compensatory strategy, but more recent evidence suggests that it might be a manifestation of neural inefficiency and noisier brain activity (Grady 2008). Sequence learning and consolidation represent dynamic changes across bihemispheric brain networks, and reduced neural efficiency, increased noise, or other changes in network dynamics with aging might lead to significant behavioral consequences. Important Scientific Research and Open Questions Offline learning has generally been studied in healthy young adults below the age of 35 with only recent attention focused on sequence skill consolidation in normal aging (Spencer et al. 2007; Brown et al. 2009). Both of these studies compared healthy older participants with a mean age of approximately 59 years to a group of healthy young participants with a mean age of approximately 20 years using modified versions of the SRTT. The SRTT can dissociate sequence-specific skill learning from general improvements in visuomotor reaction time by measuring the reaction time cost of switching from blocks of patterned or sequential trials to random trials. Participants may be told there is an underlying pattern (explicit condition), but sequence-specific learning can be demonstrated even when participants are not informed that a pattern exists (implicit condition). Sleep is required for offline learning to occur when there is explicit awareness of the underlying sequence (Spencer et al. 2007; Brown et al. 2009). These studies showed that older adults retain the ability to learn a new sequential skill. However, the results suggest that both sleepdependent and sleep-independent offline sequence learning is impaired in healthy aging. The study of sequence skill consolidation in normal aging is at its infancy. Future behavioral work is necessary to determine the properties of skill consolidation in the elderly across a range of tasks. Structural and functional imaging as well as noninvasive electrophysiological studies can shed more light on the underlying changes in connectivity and dynamics in skill memory networks that occur as we age. More animal data is required to assess the specific molecular and cellular mechanisms that account for reductions in local synaptic plasticity with aging. Such work can help to determine the following: (1) Are there certain types of sequence skills for which offline learning is completely spared or perhaps even enhanced in aging? (2) Can pharmacological agents, for example, adenosine antagonists, rescue offline learning in normal aging? (3) Do specific neuroanatomical changes such as white matter integrity or functional connectivity contribute to alterations in consolidation with aging? (4) Do measures to improve sleep quality, duration, or depth improve sleep-dependent offline learning in the elderly?.

The cognitive and neural processes involved in learning about the proper ordering of events and stimuli are called sequential learning. Sequential learning can be applied toward encoding a specific sequence in its entirety (e.g., A-C-E-F) as well as learning the distributional properties among multiple sequences, in which the learner induces the fragments or underlying regularities common to all exemplars (e.g., noticing that the fragment A-B occurs in the following three sequences: A-B-D-E, C-A-B-A, D-A-B-C). Hierarchical sequential patterns can also be acquired, a type of learning that may be crucial for much of human cognition and behavior, especially language processing. Sequential learning can occur implicitly or explicitly, under supervised or unsupervised conditions, or through any combination thereof. References Brown, R. M., Robertson, E. M., et al. (2009).

CONWAY Department of Psychology, 222 Shannon Hall Saint Louis University, St. Louis, MO, USA Synonyms Sequential processing; Serial learning; Serial order behavior Definition For most higher organisms, the order in which events occur is of paramount importance (e.g., spoken Theoretical Background Although research exploring serial order behavior has a long tradition, beginning with the early work of Ebbinghaus, it was Lashley (1951) seminal paper that elevated the importance of sequential processing in the psychological sciences. Lashley was one of the first to fully recognize and appreciate the ubiquity of sequencing in human behavior, thought, and language. For example, the sentence “please pass me the bottle that is near the glass,” has a vastly different meaning from “please pass me the glass that is near the bottle,” despite the fact that the only difference between the two sentences is the order in which the words bottle and glass occur. To take one of Lashley’s own examples, in English, an adjective generally precedes the noun. “I see the red ball” is grammatical but “I see the ball red” is not. In French, the opposite is true. In addition to language and communication, other domains in which sequential order is important include motor and skill learning, music perception and production, problem solving, and planning. Clearly, however, not all serial order behaviors are learned. Many sequential behaviors in humans and other species appear to be largely pre-wired, such as grooming movements, simple locomotion, and respiration. Thus, sequential learning encompasses the cognitive and neural mechanisms involved in the process of acquisition itself, which may be independent from other issues relevant to serial order behavior more generally, such as how serial patterns are perceived S 3048 S Sequential Learning (but not necessarily learned), represented in the mind and brain (whether they were originally pre-wired or learned sequences), or produced. There are at least three different modes of sequential learning, each corresponding to a different type of sequence pattern (Conway and Christiansen 2001): fixed, statistical or probabilistic, and hierarchical. Fixed sequential learning is perhaps the simplest type, involving learning of any arbitrary serial pattern or list (e.g., A-E-G-K), such as a phone number. In language, the use of fixed sequences can be found at different levels, including idioms and stock phrases (e.g., “once upon a time”) or even words themselves, which can be construed as fixed sequences of phonemes. This type of sequential learning is informed by a vast amount of previous research in areas such as list learning, Hebb repetition effects, short-term memory, and working memory (e.g., Marshuetz 2005). Many situations facing humans and other higher organisms involve more complex patterns that consist of statistical patterns of co-occurring elements within multiple exemplars. For example, if one were to consider the entire corpus of English speech that a listener may perceive over the course of a year, the sound sequences “fun-ny” and “ro-bot” are each likely to occur more frequently than “ny-rob.” This is true because funny and robot are English words, whereas nyrob would generally only be heard across a word boundary (e.g., “I see the funny robot”). Being sufficiently sensitive to the frequently co-occurring sounds in continuous speech, a process known as word segmentation, allows a language learner to induce which speech sounds constitute a word versus which sounds just happen to co-occur because they are the final and initial sounds of two separate words that were spoken consecutively. Word segmentation is an example of the more general phenomenon of statistical or probabilistic sequential learning, which involves inducing the common underlying distributional patterns from among multiple exemplars. In language, learners can use the statistical or probabilistic properties of linguistic input to discover the structure not just of words, but also of other properties such as phonology (sound patterns) and syntax (Saffran 2003). Although language provides a wealth of examples of statistical sequential learning, many nonlanguage domains also have probabilistic structure, in which a given element of a sequence does not perfectly predict the next element, but rather may predict it in a probabilistic fashion. Thus, statistical learning is likely used in many aspects of perceptual and motor processes, such as learning to imitate the complex movements of a dancer, or learning the melodic, rhythmic, and harmonic structures of different styles of music. The previous two forms of sequential learning – fixed and statistical – are both similar in that they involve learning the relationships between adjacent elements, a process sometimes referred to as “chaining.” However, as Lashley (1951) made clear, even though a sequence may appear as a chain of linear elements, there may exist an underlying hierarchical structure. For example, in the repeating sequence “13-2-3-1-2-1-3-2-3-1-2. . .,” each item can be followed by one of two possible items (e.g., “1” is followed by either “3” or “2” with equal probability). Only by taking into account the previous context in which an item occurs can one accurately predict the subsequent item (e.g., knowing that the “1” is preceded by “2” allows one to accurately predict “3”). With these more complex patterns, it is necessary to encode not just the preceding element in a sequence, but the previous two or more elements. Such a strategy of encoding long-distance or nonadjacent relationships among items in a sequence might provide the basis for hierarchical sequential learning, in which primitive units are combined to create more complex units (forming a “chunk”), which in turn can be combined to create even more complex units in a recursive fashion. Learning hierarchical structure has several advantages over merely learning the “flat” linear structure, including it being easier to self-repair in the event of failure and providing easier and more efficient access to subroutines of sequences (Bapi et al. 2005). In human language, hierarchical structure is especially evident in the realm of syntax. In the sentence,“The cat chased the mouse,” there are two phrases, a noun phrase (“the cat”) and a verb phrase (“chased the mouse”), with the latter containing a secondary noun phrase within it (“the mouse”). Once one has learned that a particular phrase is a noun phrase (e.g., “the mouse”) and assuming one has also learned the basic structure of English syntax, the phrase forms a single unit that can then be inserted into other situations that require a noun phrase (“The mouse ate the cheese” or “I see the mouse”). In addition Sequential Learning to language, other domains such as complex motor skills and problem solving can have hierarchical structure. Important Scientific Research and Open Questions A key question is to what extent other animal species, such as nonhuman primates, demonstrate equivalent sequential learning abilities to humans. By exploring the abilities and limitations that other primates have for processing sequential information, we can begin to understand the evolutionary origins of such capabilities in humans as well as the unique aspects of human sequential learning. Unfortunately, few studies have provided direct comparisons between nonhuman primates and humans. The evidence that is available suggests a number of commonalities as well as crucial differences between the species (Conway and Christiansen 2001). In terms of fixed sequential learning, primates appear to be capable of encoding, storing, and recalling arbitrary fixed sequences consisting of motor actions as well as visual stimuli, with proficiency comparable to that of human preschoolers. In terms of statistical sequential learning, one particular species of primate, the cotton-top tamarin, appears to have some of the same basic capabilities, at least on a par with human infants. However, in the case of hierarchical learning, there is growing consensus that nonhuman primates lack human-like proficiency. Most studies have demonstrated that apes and monkeys rarely use hierarchical routines in their spontaneous and learned actions. Whether this suggests a genuine cognitive limitation for learning hierarchical sequential patterns or is due to other methodological or contextual discrepancies is not entirely clear. Even so, the apparent species differences especially in hierarchical learning may be one crucial reason that nonhuman primates are generally incapable of acquiring human-like language. In general, the pattern of performance differences across species suggests that some aspects of human sequential learning (fixed and statistical) derives from evolutionarily old cognitive substrates, whereas hierarchical sequential learning may be a more recent development. A related key issue, then, is to understand the neural bases of sequential learning. In humans, findings from neuroimaging studies indicate that the frontal cortex (e.g., prefrontal cortex, premotor cortex, S supplementary motor areas, etc.), subcortical areas (e.g., basal ganglia), and the cerebellum play essential roles in sequence learning and representation (Bapi et al. 2005). The ways in which these different brain areas interact appear to be complex and may partly depend on the nature of the task demands. For example, in some cases, the prefrontal cortex appears necessary for learning new sequences while the basal ganglia only become active once the sequences become wellpracticed. In other cases, learning appears to occur first in the basal ganglia, which then guides learning in prefrontal cortex. A third possibility is that the basal ganglia contribute to reinforcement learning while the cortex is specialized to handle unsupervised learning situations. One issue that neuroscience studies can help resolve is to what extent the three types of sequential learning (fixed, statistical, and hierarchical) are in fact distinct mechanisms. Consistent with the behavioral findings with nonhuman primates, some evidence does suggest that hierarchical processing in humans relies on an evolutionarily newer brain region, Broca’s area (Friederici et al. 2006). A second issue that neuroimaging studies can help illuminate is whether different domains such as language, music, and skill learning are mediated by a common pool of neural regions or whether domain-specificity exists. The evidence here is mixed; on the one hand, there is evidence suggesting that Broca’s area is used across multiple domains including both music and language and therefore may act as a kind of “supramodal” sequence processor; on the other hand, a handful of studies have shown that sensory-specific brain regions (e.g., occipital cortex) are involved in the acquisition of sequential patterns in a modality-specific manner. Because the majority of sequential learning research has been devoted to a handful of domains (spoken language acquisition, motor skill learning, and music), there is a need to explore connections to other areas of cognition and behavior. Very few studies have also investigated how these three types of sequential learning skills develop in humans. One possibility is that there is a progression of developmental stages, with fixed sequential learning developing first, then statistical learning, and finally hierarchical learning. Another possibility is that the different facets of sequential learning develop more or less in parallel, or in an interactive fashion. In the realm of education, 3049 S 3050 S Sequential Processing there is a need to further explore how sequential learning is used in areas such as mathematics, reading, and writing, and whether individual differences in sequential learning may relate to various aspects of cognitive, linguistic, and educational outcomes.

Sequential Processing ▶ Sequential Learning Serial Learning ▶ Sequential Learning Serial Order Behavior ▶ Sequential Learning Synonyms U-shaped learning curve Definition Serial position curve is a “U”-shaped learning curve that is normally obtained while recalling a list of words due to the greater accuracy of recall of words from the beginning and end of the list than words from the middle of the list. First described by Nipher (1878), the serial position curve can be defined as a “U-shaped relationship between a word’s position in a list and its probability of recall.” This occurs due to a phenomenon known as Serial Position Effect. The serial position effect consists of two phenomena viz. primacy effect and recency effect. Primacy effect refers to the better recall of items from the beginning of list (first three or four items), whereas recency effect refers to the better recall of items from the end of the list (last three or four items) than middle items of the list. Theoretical Background The theoretical construct of serial position curve is that the primacy effect represents recall from a more remote memory or ▶ long-term memory which is better consolidated than the recency effect which represents recall from a more recent memory or working memory (Glanzer and Cunitz 1966). One of the ways to demonstrate serial position curve is by means of using a free recall task using a verbal learning test such as Rey Auditory Verbal Learning Test (RAVLT). In this method, the subject is given a list of various items (words of the same length) that should be remembered. The items to be remembered are presented on a manner of reading the list to the subject. Each item is introduced at a regular interval. The subject is then asked recall the items that he/she remembered in any order. The frequency of recall is plotted against the position an item takes in a list. The thus obtained graph, Fig. 1 Nipher (1878), has become known as the serial position curve of single-trial free recall. Typical is Serial Position Curve Probability of recall 1.00 .50 .00 Primacy effect 1 5 Recency effect 10 15 Serial position of item Serial Position Curve. Fig. 1 Serial position curve that the last and first few items – the recency and primacy effect – SPE’S – are more readily recalled than items in the middle of the list, which gives the graph its typical U shape as represented below. The primacy effect corresponds to the tail of the U on the left. It is called the primacy effect because these items were the ones presented first to the subject in the memory experiment. The recency effect corresponds to the tail of the U on the right. It is called the recency effect because these items were the ones presented most recently to the subject in the memory experiment. Important Scientific Research and Open Questions A common explanation of the primacy and recency effects were introduced by Atkinson and Shiffrin (1968). According to this viewpoint, the primacy effect is a result of the greater amount of attention and rehearsal allocated to the first few items on a list. This advantage in processing given to those items allows them to be transferred into the long-term memory store and thus have a higher probability of being retrieved out of long-term memory. They (Atkinson and Shiffrin 1968) attributed the recency effect to signify output from what they referred to as primary memory in the form of a short-term memory buffer. Thus, the most recent items viewed in a list are still in short-term memory and are recalled there. Evidence that the primacy effect is due to a greater amount of rehearsal to the first few items is clear in a study done by Rundus (1971). In this study, subjects were asked to rehearse out loud, and it was recorded. After reviewing the recordings, Rundus (1971) found that participants devoted more overt rehearsal to the first few items on the list. Research done by Glanzer and Cunitz (1966) S 3051 also showed that primacy is reduced when the items are presented at a faster rate, thus eliminating opportunity for extensive rehearsal by the participants. Research has also been done to demonstrate the use of short-term memory in explaining the recency effect. Because the recency effect is explained by a retrieval of items from short-term memory, it should be eliminated if a person is asked to do another task before they are asked to recall the items on the list. This was demonstrated in experiments by both Postman and Phillips (1965) and Glanzer and Cunitz (1966). Both studies provided evidence in support of the short-term memory account for the recency effect by having their participants perform a “distractor activity” after the last item on the list but before they were signaled to begin recalling the list items. The reason for recency effect is also explained in terms of the retroactive interference during encoding, i.e., the earlier items suffering interference from the later ones in the list (Oberauer 2003). Thus, the items toward the end of the list interfere with the recall of midlist items producing a recency effect. Retroactive interference during a series of outputs (output interference), on the other hand, provides an advantage for items retrieved first because the early items interfere with the later items in the output sequence. This should generate a primacy effect over output position: Items retrieved earlier interfere with items yet to be retrieved, regardless of input or spatial position. Interestingly, the serial position curve can be obtained in a free recall task of word list in all individuals even in the cognitively impaired.

Unknown to the subjects, the sequence of the target locations is repeated after a certain number of (e.g., 20) trials. Although the observers do normally not realize there is a repeated sequence, they become increasingly faster in pressing the keys corresponding to the repeated locations as opposed to random locations. ▶ Erotic/Sexual Learning Shaping ▶ Robot Learning from Feedback ▶ Shaping of New Responses Shaping by the Method of Successive Approximations Serial-Order Learning ▶ Shaping of New Responses ▶ Procedural Learning Shaping of New Responses Serious Emotional Disturbance ▶ Achievement Deficits of Students with Emotional and Behavioral Disabilities Serious Game ▶ Learning with Games BERTRAM O. PLOOG Department of Psychology, Center for Developmental Neuroscience, College of Staten Island, and Graduate School of CUNY, Staten Island, NY, USA Synonyms Shaping by the method of successive approximations; Shaping Shaping of New Responses Definition “Shaping by the method of successive approximations” – “shaping” for short – generally refers to a technique in operant conditioning in which seemingly novel behavior (i.e., behavior that does not obviously exist yet in an animal’s or person’s repertoire) is created by a careful balance of reinforcing (strengthening) responses (an operant) that approximate the terminal target behavior and extinguishing (weakening) responses that are either too dissimilar from the target behavior or are not a sufficiently close approximation of the target behavior relative to some prior performance. Shaping is a practical procedure, which is conducted by a person in order to create a new behavior (e.g., an adult teaching a child with a developmental disability to get dressed independently). Shaping may also occur as a desirable or undesirable by-product of natural, that is, not explicitly planned, consequences (e.g., improving one’s pronunciation of the French word “pain” until one is understood by the baker in Paris and receives the requested bread rather than blank stares). There is also “auto-shaping” (Brown and Jenkins 1968), which results in the creation of seemingly new behavior (such as a pigeon’s pecking at a purple hexagon), but it primarily involves classical conditioning, and it is not clear whether auto-shaping really involves shaping at all or if it is simply the acquisition of a conditioned response (pecking) that was in the animal’s repertoire all along (albeit occurring under novel circumstances, i.e., pecking at the hexagon instead of grain). New behavior can also be generated through imitation, prompting, verbal instruction (especially in humans), and experiential exposure, but these do not involve shaping per se. This section limits its discussion to the Skinnerian/operant notion of shaping. Theoretical Background B. F. Skinner described shaping in his book Science and Human Behavior (Skinner 1953, p. 91): " Operant conditioning shapes behavior as a sculptor shapes a lump of clay. Although at some point the sculptor seems to have produced an entirely novel object, we can always follow the process back to the original undifferentiated lump, and we can make the successive stages by which we return to this condition as small as we wish. At no point does anything emerge S 3053 which is very different from what preceded it. The final product seems to have a special unity or integrity of design, but we cannot find a point at which this suddenly appears. In the same sense, an operant is not something which [sic] appears full grown in the behavior of the organism. It is the result of a continuous shaping process. Shaping (by the method of successive approximations) consists of systematically applying reinforcement and extinction to some behavior (e.g., touching a tooth brush) in order to modify it such that it gradually approaches a target behavior (e.g., brushing teeth). This balance between reinforcement and extinction is known as differential reinforcement. Reinforcement might consist of food or praise that is presented when a desired response, specifically an acceptable approximation of the target behavior, occurred. For example, touching the toothbrush and picking it up may be reinforced by praise. The result is that the reinforced behavior will be more likely to occur in the future under circumstances that are similar to those when a reinforcer was earned previously. Extinction is the omission of reinforcement of behavior that was previously reinforced. For example, at some point during shaping, simply touching the toothbrush is not reinforced anymore – only touching it, picking it up and, perhaps, moving it close to the face is. The result of extinction is that the extinguished behavior (simply touching the toothbrush) is less likely to occur in the future. A by-product of extinction is that behavior becomes more variable. To stay with the toothbrush example: If simply touching the toothbrush is extinguished, the child might scream (“Look, I am touching it! Give me my token!”), touch the toothbrush with increased force, and start waving it around – the latter being a behavior that can be reinforced in order to approximate actual brushing. This increase in variability is a critical point as will become apparent in a moment when further discussing shaping. Generally, with shaping, behaviors that resemble more and more the target behavior are reinforced. In contrast, behaviors that are too dissimilar to the target behavior, or behaviors that do not meet an increasingly stringent criterion of approximating the target behavior, are extinguished. This process is illustrated in Fig. 1, with the example of shaping the target behavior “standing on the right,” when originally this was a very S S Shaping of New Responses Step 1: Position at M is most likely (mode). When shaping, movements to positions to the left of the criterion (solid line) are extinguished (EXT) and movements to the right of the criterion are reinforded (RF). EXT RF M EXT RF Frequency of Target Behavior 3054 Step 2: M shifted to the right as a result of shaping. Thus, the criterion was shifted to the right. EXT and RF apply to the new criterion. M EXT RF Step 3: M shifted further to the right, as did the criterion. EXT and RF continue to apply to the new criterion. M Step N: Steps 1 through N –1 were performed. M and the criterion line continued to shift to the right, and EXT and RF continued to apply to the current criterion. At the last step, criterion may remain at M. Left ... Middle EXT RF M ... Right Position Shaping of New Responses. Fig. 1 A schematic illustration of the mechanisms of shaping. Behavior is variable with regard to its topography (represented as a normal distribution here). The topography of a given behavior tends to occur around a mode. By extinguishing instances of this behavior with a topography that falls short of a criterion and by reinforcing those that exceed the criterion, the mode of the behavior gradually shifts in the direction of the reinforced instances low-probability behavior. A speaker might be standing habitually on the left side of a stage (Step 1, Position M). Quite often, the speaker stands a little bit to the left and to the right of M, and on very rare occasions, she might even be standing quite far from her typical left position (represented by the normal distributions over M). Should the listeners in the audience show attention to the speaker (e.g., smile, nod, make eye contact) whenever she stands just a little bit further to the right than usual and start withdrawing attention (e.g., yawn, crinkle paper, close eyes, have private conversations) whenever she stands again more to the left than at an earlier step, gradually her most likely position (M) will shift toward the right until she stands habitually at the right (Steps 2 through N). Figure 1 also illustrates the workings of a so-called percentile schedule of reinforcement (Galbicka 1994), which works by providing reinforcement whenever a response occurs that falls on or above a percentile that is set as a criterion. Important Scientific Research and Open Questions Several considerations regarding shaping are of interest. In the example above, the change in behavior occurred – at least when only considering a given phase of the shaping procedure – in what is referred to as one response class. For example, there are many ways to brush your teeth (with little or a lot of force or movement; for 1 or 2 min; with your left or right hand, holding the brush with your fist or between thumb, index, and middle fingers; etc.) A response class is defined as “a set of responses that either are similar on at least one response dimension [force, duration, or topography of brushing], or share the effects of reinforcement and punishment [reinforcement increases touching, lifting, and moving the toothbrush], or serve the same function [all responses in the brushing-teeth class produce praise]” (Malott 2008 p. 129, brackets added). It cannot be precisely defined at what point exactly a response is considered to change its membership to a different class or loses continuity with other behaviors (Skinner 1953, p. 91–95). For example, touching a toothbrush may be considered discontinuous from sticking the brush into one’s mouth and sliding it over one’s teeth. However, it is also logically defendable – as described in Skinner’s quote above – to see the change through shaping, from touching the brush to actually brushing one’s teeth, as a series of continuous behaviors, each linked through a small change in response dimension. Adjacent steps certainly belong in the same response class; early and late steps perhaps not. The differentiation between response classes may be of mostly theoretical interest but of little practical interest. When shaping is used as a deliberate training procedure to create new, complex behavior, it matters little if touching the brush belongs to a different response class than brushing teeth. In most real-life situations, shaping is combined with a technique known as behavioral chaining. The chain of brushing Shaping of New Responses teeth can be viewed as a series of links (applying tooth paste to toothbrush, touching brush, lifting brush, inserting brush into mouth, moving brush up and downward, etc.) Link 1 has to be performed before Link 2, and Link 2 has to be performed before Link 3, etc. Each link may be trained separately by shaping. Once all links are established, these links can be combined to form a chain – a process that can be done in a forward or backward manner, resulting in forward or backward chaining, respectively, the latter being the most common and probably most efficient way of training. (The rationale for this statement is beyond the scope of this section and is not critical for understanding how chaining combined with shaping can be used to create new responses.) Here is an example of backward chaining: Once moving the brush up and down in the mouth is established (Link N), one might require that the child first pick up the brush and insert it into his mouth (Link N – 1) before performing Link N, which then leads to praise. When this two-link chain is performed, Link N – 2 may be required (e.g., put tooth paste on the brush), and so on. Shaping the behavior of one link occurs most likely within one response class (e.g., changing the response dimension of force within the response class “lifting tooth brush”). Shaping the behaviors of more than one link occurs most likely across response classes (e.g., shaping the behavior of putting tooth paste on the brush and then shaping the behavior of lifting the brush to the mouth). There are two types of shaping: variable- and fixedoutcome shaping (Malott 2008, p. 150). In fixedoutcome shaping, the amount of the reinforcer stays the same for each successful performance of the critical response (e.g., one token, one sip of soda, or one word of praise with the same level of enthusiasm). In variable-outcome shaping, the amount of the reinforcer is proportional to the level of performance of the critical response (e.g., a “jack-pot” of five tokens, a half a can of soda, or many words of particularly enthusiastic praise) for a particularly well-done job. Variable-outcome shaping mimics most closely an intuitive shaping procedure that a parent might use naturally in child rearing. Very little formal research has been conducted to find out the most efficient ways of shaping. Thus, some authors have referred to shaping as an “art” (Pryor 1999; but see Galbicka 1994, who argues against this). To improve the efficiency of shaping systematically, S Pryor (1999; p. 38–39) has proposed “Ten Laws of Shaping,” including “Raise criterion in sufficiently small increments,” “Work on one behavior at a time,” and “Go ‘back to kindergarten’ (i.e., step back to an easier level) when the progression stalls.” It is clear that some parents, teachers, or animal trainers have a particular knack for teaching new behavior to their students. Those who are most successful probably acquired their own shaping skills without much awareness of naturally occurring contingencies that in turn shaped their very own shaping skills! For example, should a teacher let pass too much time between the occurrence of the student’s critical response and its reinforcer, the process of shaping might stall because the greater the delay to reinforcement, the less effective it becomes. Thus, the teacher’s behavior (shaping skill) of presenting a reinforcer as quickly as possible is naturally shaped itself by reward, that is, greater and faster success in shaping the student’s behavior. (This, in effect, is an example of a naturally occurring variableoutcome shaping procedure.) Delivering a reinforcer with too much delay, on the other hand, will be extinguished because the shaping procedure will not result in success. In other words, naturally occurring differential reinforcement shapes the teacher’s shaping skills. Unplanned differential reinforcement may also shape undesirable behavior. Consider a child in a toy store, demanding a toy with ever increasing force. When the child is merely whining, the parent might try to ignore (extinguish) the whining. But, as extinction results in an increase in variability, the child might now exhibit whining with increased force, which is hard to ignore. So, finally, the parent gives in and actually just reinforced whining with increased force – an example of shaping a response dimension (force) within a response class (whining). Such a situation might result in accidentally shaping serious temper tantrums in every toy store the child visits with his parents from now on. As a final note, so-called “clicker-training” (Pryor 1999) will be mentioned, which is a powerful technique to make shaping more efficient. For example, consider a situation in which a trainer wants to shape “jumpingthrough-a-hoop” in a dolphin as a target behavior. The hoop (and dolphin) may be 30 ft away from the trainer. If the dolphin performs a first approximation of the target behavior (e.g., swimming close to the 3055 S 3056 S Shared Cognition hoop), and the trainer offers a fish as a reward, the dolphin has to swim toward the trainer in order to receive the fish. In effect, the trainer reinforces swimming toward the trainer and not, as would be necessary, approaching the hoop. However, in clicker-training, a clicker (or whistle) has been paired previously with a reinforcer, which established the clicker sound as a socalled conditioned reinforcer (by force of classical conditioning). A conditioned reinforcer is a stimulus that has a similar effect on strengthening a response as any reinforcer, but it does not have to be consumed at the moment of presentation. In the dolphin example, instead of offering a fish to the dolphin, the approximation of swimming close to the hoop is followed immediately by the presentation of the clicker. The clicker alone will strengthen the approximation, and other behaviors that occur afterward (such as swimming toward the trainer) are not reinforced accidentally. It is important that the conditioned reinforcement properties of the clicker be occasionally maintained by following the sound with an established reinforcer (fish in the example above).

Shared Cognition RIM RAZZOUK, TRISTAN JOHNSON Department of Educational Psychology and Learning Systems, College of Education, Learning Systems Institute, Florida State University – Learning Systems Institute, Tallahassee, FL, USA Synonyms Distributed cognition; Group cognition; Shared knowledge; Shared mental model; Shared understanding; Team cognition Definition Shared cognition is the collective cognitive activity from individual group members where the collective activity has an impact on the overall group goals and activities. In a complex setting, higher levels of shared cognition are associated with more similar problem conceptualizations and solution approaches. Shared cognition is closely linked to knowledge such that knowledge possessed by effective teams has been referred to as shared knowledge, shared mental model, team knowledge, and shared understanding (Klimoski and Mohammed 1994). Shared cognition includes the knowledge that team members hold, which enables them to form accurate explanations and expectations for the task and in turn to coordinate their actions and adapt their behavior to demands of the task and other team members (Cannon-Bowers et al. 1993). Shared cognition is potentially different from the sum of individual cognition; rather, it is a result of collective cognitive, behavioral, and attitudinal activities during the group dynamic interactions which influence coordination and lead to better team performance (CannonBowers et al. 1993; Klimoski and Mohammed 1994). Shared cognition consists of two types of knowledge: team knowledge and task knowledge. Team knowledge is the knowledge associated with the general team processes and characteristics (e.g., team members’ preferences, strengths, tendencies, attitudes, preferences) (Cannon-Bowers et al. 1993; Johnson et al. 2007). Task knowledge is specific knowledge that is needed to successfully perform tasks like procedures, sequences, actions, and strategies (Cannon-Bowers et al. 1993; Cooke et al. 2000). Several methods can be used to Shared Cognition measure shared cognition. These methods include different elicitation techniques, such as cognitive interviewing, observations, causal mapping, card sorting, and representation techniques that use aggregate methods such as multidimensional scaling and distance ratio formulas (Cooke et al. 2000; Klimoski and Mohammed 1994). Theoretical Background The first theoretical perspective that underlies shared cognition is social cognition which involves social process that relate to the acquisition, storage, transmission, manipulation, and use of information for the purpose of creating a group-level interactive and collective product. One area of social cognition that represents shared cognition is team cognition. The team cognition is the theoretical framework that describes the factors that play into a team’s ability to think. The underlying assumption is that each team member possesses cognitions such as, thoughts, understandings, interpretations, beliefs, schemas, and mental models regarding some aspect of the team’s work. It is the overlap or similarity of these understandings, beliefs, mental models, etc., that researchers can assess in order to understand what is “shared” by team members. Team cognition is more than the sum of the cognition of each individual within the team as it emerges from the interaction of the individual cognition of each team member and team process. Within the team cognition model, the majority of research has focused on the sharing of mental models. Shared mental models are knowledge structure(s) held by each member of a team that enables them to form accurate explanations and expectations for the team and task, and in turn, to coordinate their actions and adapt their behavior to demands of the task and other team members. This shared knowledge generates from individual cognitive processes represented by the individual mental models that refer to a general class of cognitive construct that has been invoked to explain how knowledge and information are represented in the mind. Important Scientific Research and Open Questions Mathieu, Heffner, Goodwin, Salas, and CannonBowers (2000) examined the effects of shared mental S models on team process and team performance. They studied 56 pairs of undergraduate students performing a flight simulation. They assessed teammates’ mental models using ratings and analyzed mental model convergence by a network-analysis program. They found the process to improve from Time 1 to Time 2, but not any convergence of mental models over time. Mathieu and colleagues (2000) confirmed the distinction between taskwork mental models and teamwork mental models and found that the task mental models had an indirect effect on team performance through team processes. They found that the impact of team mental model convergence on team performance was fully mediated by team process. In 1996, Volpe, Cannon-Bowers, Salas, and Spector examined cross-training as a way of providing team members with interpositional knowledge. They conducted a 2  2 factorial between-subjects design where 80 male college students participated in a flight simulation. They found that cross-training resulted in more effective teamwork, more efficient communication, and better performance than those who had not been trained in their teammates’ responsibilities. Smith-Jentsch, Campbell, Milanovich, and Reynolds (2001) examined teamwork mental models. This refers to the understanding of the components of teamwork that are critical for effective performance as well as the relationships between those components. They proposed that people with greater experience working with teams have more knowledge and a better understanding of what makes effective teamwork. They assessed 176 navy personnel with a cardsorting task to assess their mental models of teamwork. They found a significant correlation between similarity to an expert model of teamwork (accuracy) and navy rank. Additionally, they found that there was greater similarity of mental models within highranking groups and within groups where people had been in the service for a long time. Next, they designed a training program to try to teach people to have mental models of teamwork more similar to the expert model. They assessed 42 civilian government employees that had participated in a computer-based training program. Results revealed that accuracy improved after training, as did similarity to each other’s models. Even though, research has shown that shared cognition among team members is an important factor 3057 S 3058 S Shared Knowledge linked to team performance; there is only a small amount of relevant empirical research relative to team cognition and performance, most of which is indirect. In the team performance area, the concept of shared cognition or shared mental models is often merely invoked post hoc, to help describe and interpret team phenomena. While researchers have admitted the need for direct experimental evidence, few have provided any. Most empirical studies of shared cognition have been conducted in experimental or artificial environments and with teams that were put together specifically for the purpose of the study. Finally, there is a need to study the lack of knowledge with regard to the cognitive, affective, and social mechanisms underlying effective team performance. Smith-Jentsch, K. A., Campbell, G.

A more inclusive term often used is “working memory,” which refers to an activated system that keeps products of perceptual analysis and maintains their traces in active state for on-line processing of various cognitive operations and socioemotional functions. It may be triggered either by external stimulation, by internally driven operations, or by both. Theoretical Background STM has been traditionally thought of as being limited to a short interval and a limited number/complexity of items. Nevertheless STM’s capacity is not thought to be fixed; rather it is thought to be restricted by the momentary available resources of attention that may be allotted to tend each of the items in the context of its presentation. For example, this system is susceptible to lifelong developmental changes. The recall span for digits that are presented serially aurally at a one-item-per-second rate typically increases linearly with age during childhood years; it typically asymptotes to a range of four to nine items during young adulthood, and then gradually diminishes in old age. Depending on strategies used, the complexity of the stimuli and the individual’s resources at the time of task, STM’s capacity may be extended dramatically (Chase and Ericsson 1992) or be markedly reduced (Gathercole et al. 1994). Short-term/working memory allows for on-line processing of temporal information, such as for comprehending a long sentence, as this one, or for solving a mathematical problem; and allows for on-line processing of a visuospatial problem that is presented simultaneously, by enabling a prolongation of the processing phase, to permit a step-by-step analysis of a complex set of stimuli and inhibit wrong yet predominant or salient responses. There seems to be support for multiple short-term/ working memory systems, rather than a unitary system. This evidence is often based upon findings of people who exhibit a greater capacity for verbal STM than for visual STM, or vice versa, and on individual differences in peoples’ predominant S dispositions to process stimuli in verbal/visual STM, when both are relevant. Short-term/working memory occurs due to the neural system’s activity that maintains a set of signals active, for example, by evoking a heightened or dampened activity in a distributed neural network. These may be expressed by changes in firing rates or by changes in graded potentials (Hebb 1949). Short-term memory decays rapidly with time and is sensitive to interferences and blurring. Forgetting of materials held in STM may be accounted by the return of the activity of this network back to its baseline or default levels. Rehearsal strategies may be employed to refresh traces of a memorized set of stimuli to postpone rate of decay and increase its accuracy. Retrieval from STM of recently experienced stimulation or of internally represented experiences is based on drawing short-term activity traces that are generated by the working memory system(s). It has been suggested that during the first years of life, children use no controlled strategy in the recall process (Palmer 2000); this is followed by a period in which a visual strategy prevails, followed by a period of dual visualverbal coding before the adult-like strategy of verbal coding finally emerges. Baddeley and Hitch’s seminal model of working memory offered a structural view of working memory. According to this framework, the operating working memory system is comprised of three integral divisions: a central executive controller of attention resources, and two content-based processors: an articulatory loop and a visuospatial sketch pad (Baddeley and Hitch 1974). More recent scientific developments proposed that the articulatory loop that holds on mostly language-like stimuli is comprised of an “in-house” short-term articulatory control process, which acts as a momentary translator into modalities, and a phonological store which encodes and registers the phonetic data (Nairne 1996). According to this model, the phonological loop seems to be the most likely candidate to be activated in the processing of both auditory and visual verbal stimuli. Nevertheless, visual stimuli, even of verbal nature, may activate a bottom-up visual perceptual system that is related to the inner scribe component of the visuospatial sketch pad. This component is responsible for active rehearsal of information held 3059 S 3060 S Short-Term Memory within a passive visuospatial cache, and is involved with extraction of information for execution of voluntary motor acts. Important Scientific Research and Open Questions STM is highly susceptible to any number of transient conditions that compromise resources, such as fatigue, physical illness, or nutritional deficiencies such as iron deficiency. These effects are often refractory, and STM capacity improves when this condition is amended. At the same time, certain processes may divert normal development of STM capacities in a more chronic manner. An understanding of the mechanisms involved in transient STM deficits may generate novel research directions in populations who exhibit chronic deficits. STM deficits are often diagnosed in people who are intellectually challenged, people with attention deficit disorders, with or without hyperactivity, and often accompany various verbal and nonverbal learning disabilities. STM is susceptible to an array of specific genetic, structural, and nutritional aberrations such as a result of intrauterine growth restriction (Geva et al. 2006), specific genetic syndromes, as Trisomy 21 and Williams syndrome (Purser and Jarrold 2005; Vicari and Carlesimo 2006), neuronal degenerative diseases, and more. Certain focal neurological insults may also result in lowered STM capacities. The mechanisms involved in these clinical conditions are not yet fully understood. An array of conditions that are related to alterations in neural activity, neural integrity, and neural maturation or in the spread of activation may result in STM deficits. In order to better characterize the system(s) that enable STM/working memory processing to improve learning, it may be important to explore the following directions: Firstly, to date the literature on STM/working memory mostly concentrates on studies using verbal stimuli that are presented sequentially and or use of complex visuospatial information that is often presented simultaneously. It may important to find ways to better equate similar encoding opportunities of auditory and visual stimuli. Using a presentation of sequential visual items and use of nonverbal auditory spans may be important to better characterize the interrelationships between the executive controller network, the articulatory loop, and the visuospatial sketch pad. Secondly, the interrelationships between sensory reception systems (i.e., their sensitivity, range of reactivity, and accuracy) and the initial registration mechanisms in STM as well as studies of factors that affect de-blurring and reactivation of previous recollections’ traces may advance our understanding of the mechanisms involved in rehabilitation of affected STM/working memory systems. Finally, in view of recent developmental studies of highrisk populations, it seems that assumption of an immediate and automatic processing at the phonological loop needs to be carefully studied and validated in children or adults who are diagnosed with an atypical neural-developmental process (Geva et al. 2006). Thus, a careful study of the factors that affect STM/working memory functions in various clinical populations who experience learning deficits may be fruitful both for theoretical purposes and for intervention purposes to improve learning.

Sidman Equivalence ▶ Learning of Equivalence Classes Definition Signal detection models are probabilistic representations of the structure of the information and the rules for decision-making that can be applied to a specific decision problem. A completely specified signal detection model requires (a) the definition of the dimension (s) of the evidence or information, (b) selection of the probability distribution(s) for the random variable used to represent the evidence or information, and (c) the rule for selecting the criterion values used to translate the values of that random variable into discrete decisions. Theoretical Background Sight Word Spellings ▶ Mental Graphemic Representations Sign Language ▶ Verbal Behavior and Learning The formal foundations for signal detection models were developed as a part of the effort to develop radar and sonar technologies, with much of this work occurring during and after World War II. The approach is general enough to have allowed for a wide range of applications, including statistical signal processing, telecommunications, statistical decision-making, quality control, and human perception, memory, and cognition, with special applications to training and evaluating diagnostic abilities in medicine. S S Signal Detection Models The application of signal detection models to human performance dates to the mid-1950s, with critical initial work in human psychophysics (W. P. Tanner and Swets 1954). The introduction of signal detection models to psychophysics was in part motivated by a concern that classical approaches to psychophysics did not make a distinction between the total amount of perceptual evidence available in two or more different states of the environment and the manner in which that evidence was used. These two aspects of human performance are referred to as sensitivity and bias within the literatures on signal detection theory (Green and Swets 1966). The basic elements of a signal detection model can be illustrated by considering the general problem faced by any system (e.g., a human observer, a radar system, etc.) that needs to detect the presence of a specific type of signal (a target) that is embedded in a background of irrelevant noise. Thus, the environment in which the system operates can be described as existing in one of two possible states at any point in time: one in which the target signal is present along with the background noise and one in which only the background noise is present. The system generates one of two possible responses to the environment: one indicating that it judges the target to be present and one indicates that it judges the target to be absent. This is represented schematically in Fig. 1a, along with the standard labels for the outcomes associated with each combination of true state of the environment and system response. Assume that the system has some method for encoding the level of evidence available on any encounter with the environment with respect to the presence of the signal, and that the level of evidence encoded is a combined function of signal strength and the level of noise. Let X be the random variable representing the level of evidence and assume that X is distributed as a Gaussian random variable, with f ðxjs þ nÞ denoting the pdf for this random variable when the signal is present in the noise, and f ðxjnÞ denoting the pdf when the signal is absent. Assume that these pdf ’s are ordered with respect to their means, such that msþn > mn , and that the variances for the two pdf ’s are equal, with ssþn ¼ sn . At this point, the model is specified in terms of the dimension of interest (evidence for the presence of the signal) and the applicable probability distribution. In order to use this model to make predictions for behavior or performance, what remains is to specify the rule for generating a detection response. Assume that there is a critical level of evidence, xc , the specific value of which is set by the system, such that when X  xc the system judges the signal to be present, otherwise judging the signal to be absent. This decision rule is applied to both probability distributions, allowing for both types of responses to be generated for both states of the environment. The model for this (example) situation is now complete. The model (shown schematically in Fig. 1b) can be used to make predictions for performance in the following ways. First, predictions regarding probabilities of each of the four outcomes in Fig. 1a can be obtained by integrating the pertinent pdf relative to the value of xc . For example, the probability of a “hit” R1 can be obtained as f ðxjs þ nÞdx. Predicted sensitivxc ity of the system to the presence of the signal can be quantified in terms of the distance separating the pdfs, System Response True State of the Environment 3062 "Signal present" "Signal absent" Signal present hit miss Signal absent false alarm correct rejection xc (criterion) f(x | n) f(x | s + n) X (evidence variable) Signal Detection Models. Fig. 1 (a) Outcomes associated with the pairing of each possible true state of the environment with each possible response. (b) Schematic representation of a fully specified signal detection model for detecting the presence of an arbitrary signal embedded in noise Signal Detection Models S 3063 The application of signal detection models has been quite widespread, including both natural and engineered systems, due in no small part to the generality of the approach. The approach has included incorporation of models for learning and applications to multidimensional (multivariate) issues (Ashby and Townsend 1986), though unidimensional models are far more common, particularly with respect to human performance. Incorporating Learning into Signal Detection Models Signal detection models for learning have often been represented within a dynamic systems framework. In early models (Atkinson 1963) sensory processes were modeled through the changes in activation of a sensory state that corresponded to a particular aspect of the experimental paradigm. Decisional processes were then incorporated as a set of responses assigned to the various sensory states. These models were used to examine the effects of various manipulations on response bias, including types of feedback and presentation schedules (Tanner et al. 1970). The majority of models addressed learning in unidimensional applications, though a more recent extension to multidimensional contexts (Ashby 2000) incorporates random walk theory in order to address within-trial dynamics. Connecting Theory and Data An ongoing issue with respect to the application of signal detection models concern methods for connecting theory and data. The problem is one of identifying a unique model for a given set of experimental data. This issue is of particular concern for multidimensional signal detection models, given the increase in complexity and number of potentially-free parameters relative to the degrees of freedom in the data. To illustrate these issues, consider the extension of the unidimensional model in Fig. 1 to two dimensions. A common and simple way of visualizing this situation y Important Scientific Research and Open Questions y and the predicted bias of the system is captured by the location of the critical value of the evidence variable xc . x x Signal Detection Models. Fig. 2 Illustration of mean shift integrality (left) and an alternative configuration (right). Left panel: both distributions and the decision bound have shifted up by the same amount. Right panel: negative bivariate correlations in all distributions give rise to the same pattern of response data as the shifted configuration on the left is in terms of contours of equal likelihood, with a linear decision criterion for each dimension. Models of this form allow for characterization of issues such as interactions among dimensions (Ashby and Townsend 1986). These interactions can then be identified at the level of the perceptual evidence (parameters of the multivariate distributions) and at the level of the rules for generating responses (parameters of the decision bounds). A simple example in which model identifiability is a problem occurs when both the multivariate distributions and the decision bounds shift. In Fig. 2, the distributions on the right are higher than those on the left, but their positions relative to the decision criterion are the same as those on the left. In terms of response data, such a situation is indistinguishable from the configuration in the right panel of Fig. 2. Such ambiguity prevents conclusions being drawn as to whether dimensional interdependencies exist at the perceptual or decisional level. The statistical issues associated with model estimation and identifiability have been noted frequently (Ashby and Townsend 1986). A variety of methods have been proposed (Thomas 2001), although to date no comprehensive comparisons of relative robustness have been published. However, there are indications that by using multiple statistical methods, inferential errors can be minimized. Such multi-method approaches are consistent in spirit with seminal S 3064 S Signal Detection Theory research using multi-measure approaches to estimate multidimensional signal detection models (e.g., Ashby and Townsend 1986).

Signal Processing ▶ Phonetics and Speech Processing Significant Learning ▶ Person-Centered Learning Similarities in and Differences Between Nonhuman Ape and Human Cognition: The Cultural Intelligence Hypothesis ESTHER HERRMANN Department of Developmental and Comparative Psychology, Max Planck Institute for evolutionary Anthropology, Leipzig, Germany Definition Despite sharing many cognitive abilities with other animals, humans also have a specific set of cognitive skills, such as language, mathematics, and the ability to create complex technologies and social institutions, skills which are not even possessed by their closest primate relatives, the great apes. The cultural intelligence hypothesis argues that this is mainly due to a specialized set of social cognitive abilities for participating and exchanging information in cultural groups. These social cognitive skills emerge early in ontogeny and enable young children growing up within a cultural group to benefit from the preexisting knowledge and skills of others around them. Children learn and are taught to use the already existing symbols and artifacts such as language, tools, and Arabic numerals. This species’ unique sociocultural world then supports further development in many different cognitive domains. Theoretical Background Nonhuman great apes (orangutans, gorillas, chimpanzees, and bonobos; hereafter great apes) are humans’ closest relatives. They all shared a common ancestor around 15 Ma ago, with bonobos, chimpanzees, and humans also sharing a common ancestor around 6 Ma ago and 98% of their genotype. In addition, based on their close evolutionary history, they also share many morphological and physiological characteristics and the majority of human cognitive abilities, such as an understanding of space, the ability to discriminate and quantify objects, to recognize individual conspecifics and third party relationships, and to understand conspecifics as goal directed and intentional beings (Tomasello and Call 1997; Tomasello et al. 2005). However, humans have certain cognitive skills which are not Similarities in and Differences Between Nonhuman Ape and Human Cognition: The Cultural Intelligence Hypothesis found in their closest relatives, such as language, symbolic art, mathematics, and the ability to generate complex technologies such as computers or airplanes and create social institutions such as religions. The questions of how and why specific cognitive skills evolved in primates, and especially the very distinctive cognitive skills of humans, have long been of interest, and various hypotheses have been proposed to answer these questions. One proposal to explain uniquely human cognition is the general intelligence hypothesis: humans’ extralarge brains enable them to perform all kinds of cognitive operations better and faster than other species based on more memory, faster learning, faster perceptual processing, more robust inferences, longer-range planning, and so on. However, other theorists suggest that cognitive abilities evolve in response to relatively specific environmental challenges. Therefore, it has been proposed that primate physical cognition evolved mainly in the context of navigation and foraging for patchily distributed and seasonal food, such as ripe fruits, new leaves, flowers, and extracting food that is not directly perceptible (including the use of tools). Besides this ecological intelligence hypothesis, other researchers have proposed that living in a social group and dealing with conspecifics creates additional cognitive challenges beyond dealing with and the manipulation of inanimate objects. Conspecifics behave spontaneously on their own and are therefore unpredictable. Moreover, the behavior of a conspecific can be influenced, controlled, or exploited in order to gain useful information. Therefore, the “social intelligence hypothesis” proposes that primates’ special cognitive abilities evolved mainly in response to the especially challenging demands of a complex social life characterized by constant competition and cooperation with conspecifics (Byrne and Whiten 1988). In a modified version of the social intelligence hypothesis Whiten and van Schaik (2007) recently proposed interdependence between having multiple traditions and intelligence, focusing mainly on social learning and innovation. The common idea shared by the different social intelligence hypotheses is that the evolution of social cognitive skills in primates has been mainly fuelled by constant competitive and exploitative processes between conspecifics. However, these social intelligence hypotheses cannot fully explain the differences in cognitive abilities between great apes and S humans. In the case of humans, one variant of the social intelligence hypothesis emphasizes the role of cooperation. According to this theory, humans are extraordinarily social, and their distinct cognitive skills evolved mainly in response to their complex sociocultural life which depends highly not only on competing with others but also on complex forms of collaboration (Vygotsky 1978). To successfully live and exchange information within the cultural world human children are born into, it is necessary to possess sophisticated social-cognitive skills such as social learning, communication, understanding the intentions of others, and the motivation to share knowledge with other individuals. These skills enable young children to benefit from the accumulated skills and knowledge of their fellow human beings. They learn and are even explicitly taught to use already existing artifacts and symbols such as language, tools, and Arabic numerals (Vygotsky 1978; Tomasello et al. 2005). However, other great ape species such as chimpanzees and orangutans also have special traditions and culture, in which a variety of behaviors are transmitted across generations. These great apes are able to learn new behaviors by observing others; however, there is little evidence that learning is assisted by teaching. In general, apes also do not rely on participating in such cultural interactions to the same extent as humans. The “cultural intelligence hypothesis” therefore suggests that the distinct cognitive skills of human adults which are not found to the same degree in other primates are a product of specialized social cognitive skills which emerge early in ontogeny and make it possible to participate in the cultural world, correspondingly allowing the distinctively complex development of human physical and social cognition (Herrmann et al. 2007). Important Scientific Research and Open Questions To test and compare two alternative hypotheses about the evolution of human cognitive abilities – the cultural versus the general intelligence hypothesis – Herrmann et al. (2007) presented a comprehensive battery of cognitive tests to large numbers of two of human’s closest primate relatives, chimpanzees, and orangutans, as well as to 2.5-year-old human children. The test battery consisted of 16 different nonverbal tasks assessing all kinds of cognitive skills, involving both physical and social problems relevant to primates in 3065 S S Similarities in and Differences Between Nonhuman Ape and Human Cognition: The Cultural Intelligence Hypothesis their natural environment. While the tests of the physical world consisted of problems concerning space, quantities, tools, and causality, the tests of the social world required subjects to imitate another’s solution to a problem, communicate nonverbally with others, and read the intentions of others from their behavior. If it is the case that humans have greater general intelligence than great apes, children should differ from chimpanzees and orangutans uniformly across all the physical and social cognitive tasks. The findings did not support this hypothesis. Two-and-half-year-old human children and chimpanzees had very similar cognitive skills for dealing with the physical world; however, the same children, who were using language but were still years away from reading, counting, or going to school, had already more sophisticated cognitive skills than either one of the ape species for dealing with the social world (Fig. 1). In addition, Herrmann et al. (2010) examined the structure of individual differences in the cognitive abilities of human children and chimpanzees in this comprehensive range of cognitive tasks. Even if human children were not more intelligent overall than other great apes but only more skillful in solving social cognitive problems, it is still possible that a general intelligence factor could explain the individual differences within a species. One hypothesis is that only humans exhibit a general intelligence factor, which would mean Physical domain a 1.00 that children who are great at solving physical tasks are also great at dealing with social tasks. But this was not the case. Neither the childrens’ nor the chimpanzees’ performances could be explained by a general intelligence factor since individual performance on one task did not predict performance on other tasks across the board. Rather, results showed a similar factor for spatial cognition for both species – but beyond these commonalities, the two species showed different factor structures. While one factor comprising both physical and social cognitive tasks was found for chimpanzees, children had two distinct factors for physical cognition and social cognition. Thus, 2.5-year-old children not only showed more sophisticated cognitive skills in the social domain alone rather than across the board, but there was also no general intelligence factor found for children. Instead, a factor for social cognition was established. Together, these findings suggest that humans share many cognitive skills with their closest living relatives – especially for dealing with the physical world – but in addition, they have evolved some specialized and more integrated social cognitive skills. With these special skills of social cognition, emerging early in ontogeny, young children are well equipped to acquire all kinds of knowledge and skills through communicating, collaborating, and socially learning from others in their cultural group.

Fig. 1 Physical (a) and social (b) cognitive performance of human children, chimpanzees, and orangutans (Taken from Herrmann et al. 2007) Similarity Learning unique sociocultural world then facilitates all their physical and social cognitive skills. Hence, this set of species specific skills suggests that humans compared to other animals have a specific biological adaptation for the complex social life and cultural world that they themselves have created. Such large-scale comparisons provide a first step toward systematically investigating similarities in and differences between humans and other great apes and open the way for mapping out in a systematic way the cognitive skills of other primate species across the evolutionary spectrum. This will then provide the kind of detailed description of primate cognition needed to reconstruct both the biological and cultural evolution of human cognition. Furthermore, much remains unknown about the physical and social cognitive development of great apes and how it compares to human children’s development. This kind of research is necessary to gain a better understanding of developmental differences in cognition across humans and great apes and especially of the way in which ontogenetic differences influence the cognitive differences found between human adults and our closest living relatives. Finally, another important avenue for future research is to investigate the similarities and differences in temperament and emotions that might contribute to the extraordinary social nature of humans and other great apes, including their special social cognitive skills.

Similarity Learning MARCEL WORRING Intelligent Systems Lab Amsterdam, University of Amsterdam, Amsterdam, The Netherlands Synonyms Interactive image retrieval; Metric learning; Relevance feedback learning Definition When describing images, humans often resort to similarity defining the characteristics of the image in relative terms rather than absolute terms. Subtle differences between images can be indicated by a human easily while completely describing a single image is a challenging task. Cognitive evidence also suggests that we interpret objects by relating them to prototypical examples stored in our brain. So similarity is a fundamental property and of great importance in retrieval and categorization tasks alike. Similarity learning is the process of determining a function d(a,b), which finds the optimal relation between two different data items a and b in a quantitative way. In general, defining similarity for structured symbolic or numeric data is rather straightforward, but defining similarity from a human perspective is difficult (Tversky 1977), this is especially true for visual data for which there is a semantic gap between what a system can extract from the sensory data and the interpretation the same data has for a human observer (Smeulders et al. 2000). In this respect, similarity learning is viewed as determining a function d(a,b) best matching the user interpretation of the data items and their relations. S 3068 S Similarity Learning Theoretical Background The starting point in defining similarity is a feature function fa, which takes the sensory data of a and summarizes it by a feature vector describing perceptual properties like color, texture, and local shape. Function d(a,b) can then be expressed in terms of the feature vectors fa and fb, yielding a perceptual distance function. This function in many cases is such that it follows the metric properties dða; aÞ ¼ 0; dða; bÞ ¼ dðb; aÞ and the triangular inequality dða; bÞ þ dðb; cÞ  dða; cÞ. However, there are also many applications where d is nonsymmetric or where the triangular inequality only holds locally. And indeed, given a set of features, many functions are in use to compute the similarity like Histogram intersection, Minkowski distance, Euclidean distance, or Earth Movers Distance (Smeulders et al. 2000). As the user interpretation in general is subjective, learning the similarity requires relevance feedback RF from the user. So similarity learning is an iterative process defined as follows: RFi d i ða; bÞ!d iþ1 ða; bÞ where d 0 ða; bÞis a perceptual distance function. Based on some initial query on the dataset, the system presents a result set to the user conforming to d 0. The user is then asked to give feedback on the result, typically identifying correct and incorrect elements. From there, in an iterative manner, the system updates its internal definition of similarity and presents a next set of results, until the user is satisfied with the results or until the user reaches the conclusion that such a result cannot be achieved. This process is illustrated in Fig. 1. Due to the semantic gap, learning the similarity function is required for two reasons: ● The user interpretation of the images can be sub- jective and hence observer dependent. ● The mapping from perceptual features to interpre- tation in terms of concepts is complex. Because of this distinction, we have at least two forms of similarity learning that play a role. To learn the subjective interpretation of the user requires shortterm learning where typically the user is interacting in a single session with the system. Long-term learning on the other hand is based on several interactive sessions from a larger number of users. As in the latter case subjective interpretations are averaged out, we can start to learn the complex mapping from perceptual distance functions to conceptual similarity. One of the first methods for similarity learning in image retrieval and conceptually the simplest is by Rui et al. (1998) and is based on learning a similarity function as linear combination of distances for individual elements of a feature vector. After that many other methodologies have been defined (Smeulders et al. 2000, Zhou and Huang 2003) based on different similarity functions, different types of feedback, and different ways of updating the similarity function. Apart from updating the similarity function itself it is also possible to update the interpretation of the similarity function in terms of revising the probability associated to certain concept occurrence. Recent methods have taken the importance of prototypical data elements (Pekalska et al. 2006) or images Distance indicates (dis)similarity Before feedback User selection of positive elements (dark), others assumed negative After feedback positives closer together others further away Similarity Learning. Fig. 1 Simplified overview of the concept of interactive similarity learning Simon, Herbert A. (1916–2001) for defining similarity a step further. In these methods, a small set of prototypical images from the collection are selected, for example, by taking the center elements of data-driven clusters. Now a new feature vector is defined based on the distances of an element to each of those prototypes. This new feature space has good performance in terms of classification of the elements. When projected to two dimensions for visualization, this space allows the user to interact directly with the similarity between different images by changing the positions of individual images on the screen (Nguyen et al. 2007).

Although methods for learning similarity have been around for quite some time, there are still many challenged ahead. Some we highlight here: ● Scalability: image collections are growing rapidly in size, but interactive learning of similarity requires interactive response times. ● Implicit Feedback: indicating positive and negative examples are the de facto standard in learning similarity, yet few users are willing to do this at large scale. Implicit feedback mechanisms seem more appropriate. ● Bootstrapping: learning similarity hinges on a good starting point, making wrong choices here might lead to biased interaction processes not leading to the right result. ● Learning Semantics: truly understanding the relation between low-level perceptual distance functions and high-level conceptual relations and obtaining this relation through interaction remains a challenge.

Similarity-Based Problem Solving by Animals ▶ Analogical Reasoning in Animals Simile ▶ Analogy/Analogies: Structure and Process Simon, Herbert A. (1916–2001) NORBERT M. SEEL Faculty of Economics and Behavioral Sciences, Department of Education, University of Freiburg, Freiburg, Germany Life Dates Herbert Alexander Simon was born in Milwaukee, Wisconsin, on June 15, 1916. During his school education he developed a strong interest in science. Later in his life, Simon was influenced by his mother’s younger brother, Harold Merkel, who had published books on economics and psychology. Thus, Simon became S 3070 S Simon, Herbert A. (1916–2001) interested in the social sciences. He received his Ph.D. in political science from the University of Chicago in 1943. Then he served as professor of political science at the Illinois Institute of Technology until 1949, where he began intensive study of institutional economics. Simon then accepted a position as professor of administration and chair of the Department of Industrial Management at Carnegie Institute of Technology, where he remained until his death, teaching subjects as diverse as psychology and computer science. As is already evident from his teaching career, Simon never stopped studying new subjects. For example, he studied mathematical economics from 1950 to 1955, developing and proving the Hawkins-Simon theorem with David Hawkins on the “conditions for the existence of positive solution vectors for input-output matrices” as well as theorems on near-decomposability and aggregation. Interestingly, Simon also applied these theorems to organizations. Not surprisingly, he also became highly interested in problem solving and the emerging field of computer science, and in the mid 1950s, he concluded that these two fields of interest could be linked through simulations of problem solving with computer programs. Altogether, it can be said that Herbert Simon was an ingenious researcher who was accordingly awarded with numerous accolades, among which the 1978 Nobel Memorial Prize in Economics for his pioneering research into decision making within economic organizations deserves special attention. Simon died on February 9, 2001. Theoretical Background During his entire life, Herbert Simon was a true interdisciplinary scientist who was affiliated with several Carnegie Mellon departments, such as the School of Computer Science, the Tepper School of Business, and the departments of Philosophy, Social and Decision Sciences, and Psychology. Accordingly, he contributed to various fields of interest, such as decision making, problem solving, development of expertise, and artificial intelligence. Already as a young scientist, Simon became popular due to his research on industrial organization and decision making. As a contrast to neo-classical theories of rational decision making, Simon coined the term bounded rationality, according to which individuals (as parts of organizations) tend to maximize utility functions under current constraints in pursuit of their self-interests. According to Simon’s theory of subjective expected utility, bounded rationality refers to a rational choice among alternatives that takes into consideration not only the organizational constraints of decision making but also the cognitive limitations of the decision maker. Bounded rationality became a central issue within the realm of behavioral economics, and Simon’s research on decision making became an important paradigm in industrial organization and organizational psychology. Simon was a pioneer in the field of artificial intelligence. Together with Allen Newell, he developed the General Problem Solver (GPS) in 1957, a technique for separating problem solving strategies from particular problems that also includes a theory for simulating human problem solving based on production systems. Related to this seminal work on problem solving was Simon and Feigenbaum’s development of the EPAM (Elementary Perceiver and Memorizer) theory, one of the first theories of learning to be implemented as a computer program. Closely related to the study of human problem solving was Simon’s interest in studying the role of knowledge in the development of expertise, especially in the area of chess (Simon and Chase 1973). He found that characteristics of becoming an expert include a minimum of 10 years of consistent practice and an early phase of learning characterized by excitement and enjoyment without outcome-oriented objectives. Ericsson continued this research on expertise development and focused on the role of deliberate practice, which encourages novice learners to pursue new levels of performance in a field of practice (Ericsson et al. 1993). Simon believed that the study of human problem solving required new kinds of assessment and measurement. Therefore, together with Ericsson he developed the experimental technique of verbal protocol analysis (Ericsson and Simon 1980), which is still the standard today. Contributions to the Field of Learning Herbert Simon was, of course, also interested in how humans learn, and he thus developed the EPAM (Elementary Perceiver and Memorizer) theory with Edward Feigenbaum (Feigenbaum and Simon 1984). Simulation and Learning EPAM operates with discrimination nets to regulate the flow of information processing. It was one of the first computer programs which could simulate verbal learning and was also influential in formalizing the concept of a chunk. Later, the theory was extended to concept learning and the acquisition of expertise. Basically, it assumes that learning consists in the growth of discrimination nets. Additionally, EPAM contains a limited short-term memory and several attention mechanisms. Information processing occurs in EPAM through various steps: First, a stimulus is perceived and its features are identified. Second, the features are arranged within the discrimination net in such a way that an association with particular content from long-term memory can be generated. Third, simultaneously with the arrangement of the features in the discrimination net a process occurs in the net in order to decide whether learning is necessary (e.g., adding additional features). Finally, the computational system acts or the next stimulus is processed. Related computational cognitive models of thinking and learning are CHREST and SOAR, which are described in separate entries of this encyclopedia. In addition to his pioneering work on EPAM and the development of expertise, Simon also contributed to educational issues. For instance, when the discussion on situated learning and education culminated in the 1990s in fundamental criticism of cognitive theories of learning, especially in mathematics education, Simon took issue with the overstatements of the situated learning approach and emphasized the relevance of traditional cognitive research on learning and transfer (Anderson et al. 1996). To sum up Simon’s contributions to several disciplines, it can be stated that he was a real polymath and one of the most influential economic and social scientists of the twentieth century. 3071 References Anderson, J.

Theoretical Background FRANCO LANDRISCINA Allianz, E-Learning, Trieste, Italy Synonyms Conceptual change; Mental models; Mental simulation; Model-based learning; Modeling and simulation; Organizational learning theory; Perceptual simulations; Thought experiments Definition The etymology of the word simulation (Latin: simulō, imitate) shows that it could also mean to pretend and therefore have a negative connotation. Simulation is often seen as a false representation of the real world. In many Sci-Fi films, the protagonist finds him lost in a simulated world, created to hide the real world. This negative connotation can hark back to Plato’s conception of the “mίmZsiς” (mimesis, Greek term for simulation) as the imperfect copy or fictitious replica of reality. On the contrary, according to Aristotle, the mimesis is a means to know nature through representations which can be valid and acceptable. This shifting of the emphasis from imitation to representation corresponds to the shifting of the focus from the superficial aspects of a simulation, for example, interactivity, to the underlying model, as happens currently in model-based instruction. In this wider concept of simulation, mental models assume a central role. In his dialogue “Politics” (Statesman), Plato describes the cognitive role of the models, or “paradeigmata” (“paradeίgmati”). In order to illustrate the nature of the statesman, one of the characters of the dialogue refers to the model of the weaver, where the technique of the politician is compared to that of the weaver who weaves fibers of different nature to create a single fabric. In general terms, Plato describes the usefulness of the model as a process of identification of similitudes and differences. Examining the similitudes and the conceptual differences between the model and the phenomenon being studied, the subject transforms his initial ideas, confused and approximate, into a more precise and rigorous comprehension. This is also what The role of mental models in simulation was first highlighted by organizational learning theorists. According to Senge (1990, p. 8), mental models are “deeply ingrained assumptions, generalizations, or even pictures and images that influence how we understand the world and how we take action.” Senge fostered the idea of computerized simulations, called microworlds, which could allow the managers of an organization to interpret their real roles and understand how these interact among themselves. The realization of microworlds of this type is one of the practical applications of system dynamics, a computer-aided approach to policy analysis and design in organizations. System dynamics provides a series of methods for the elicitation, articulation, and description of the tacit knowledge contained in the mental models of the experts and for the building of computer-based simulations on the basis of such models (Ford and Sterman 1998). This corresponds to the shifting from the concept of model as representation of reality to a concept of the model as a cognitive artifact. The relation between mental model and education has been examined in depth by Seel (2003) who has formulated a learning and teaching theory based on models (Model-Centered Learning and Instruction). Model-centered learning can be described as a progression of mental models, from an initial state, characterized by the student’s preconceptions, to a desired final state, of causal explanation. One of the general functions assigned by Seel (1991) to mental models is mental simulation. In this interpretative framework, computer-based simulation is seen as a teaching methodology, able to facilitate model-centered learning and is particularly effective when the learning objective requires a restructuring of the individual mental models of the students (seen here as cognitive structures in longterm memory). This is the case, for example, of the preconceptions with which the student starts learning scientific concepts, or the mental models which oppose the change of strategies and behaviors in the organizations. Simulation and Learning: The Role of Mental Models Seel distinguishes between: ● Mental model, the internal and subjective model of a system ● Conceptual model, which is objective and shared by a scientific community ● Design and instructional model, used for building the user interface and the learning tasks In order to be used as a simulation model, a conceptual model must be formalized in mathematical terms (such as rules and equations) which can be developed as computer programs. In a simulationbased learning environment, the student interacts with such a model only in a mediated way. Faced with a learning task, he must then build his own mental model of the phenomenon being studied and use it as a basis for prediction, inference, and explanation. The field of Human-Computer Interaction (HCI) offers a series of design principles that can be applied to help the students build a correct mental model of the system. This requires a preliminary analysis to define the characteristics of the intended users and how they will be using the software. In the words of Senge (1991, p. 72): “Simulations with thousands of variables and complex arrays of details can actually distract us from seeing patterns and major interrelationships.” In the case of “black-box simulation models,” the student can explore the behavior of the system, but the underlying conceptual model remains hidden and can only be inferred by what is happening on the screen. This could lead the students to believe their partial conclusions are undisputable assumptions. For example, a simulation game such as SimCity® presents thousands of possible scenarios and applications, but it doesn’t show the rules put in the game by its creators. Facing the events which occur as the consequence of its own actions, the players tend to automatically attribute some rules to the system, which can coincide with those present in the program or be simply the result of their mental models. Instead, “glass-box models” simulations openly show the relationships between the variables and therefore the hypothesis at the basis of the model. This too might not be sufficient. It is tempting to identify the equations of a model with the model itself, but it has to be borne in mind that the same model can be implemented using different equations, and models have different properties than equations. S 3073 The system model can also be shown in a visual way. For example, in a simulation of an ideal gas, the underlying physical “billiard ball model” can be shown through the animation of molecules represented as rigid spheres, clashing with each other and with the walls of the container in a perfectly elastic way. For the purposes of the conceptual change, the construction of a simulation model is an activity potentially more effective than the simple exploration of the behavior of a preexisting model as the students (and the teacher) can represent, share, and test their mental models. In the building of a simulation to solve a problem the student must: 1. Decide how to describe the system to be studied in terms of objects, relationships, and quantities 2. Recognize which principles to apply to solve the problem 3. Infer qualitative rules between the values of the variables These activities are similar to those described by VanLehn and van de Sande in their study of the acquiring of conceptual expertise from modeling in elementary physics. The expertise in this domain is characterized by a qualitative understanding of real world situations. The capacity of solving conceptual problems arises from extensive practice of a certain kind and develops following a sequence from a superficial understanding, to a semantic understanding, and finally to a qualitative understanding. VanLehn and van de Sande (2009, p. 374) suggest that the students should not circumvent the model-construction and model-interpretation processes and focus on increasing their semantic understanding of the models. In many cases, the restructuring of the mental models remains nevertheless an objective which is difficult to achieve and, therefore, the extra-technological factors which characterize the context become decisive, among which are, for example, the attitudes and the expectations of the participants, the organizational and management models, the social relations and the relational systems underlying the use of technologies. Seel stresses the importance of the relationships between internal models and external models, where the former are implicit and individual, while the latter are explicit and can be shared. From this point of view, the task of the teacher is that of aiding the students to externalize S 3074 S Simulation and Learning: The Role of Mental Models and discuss their own mental models and internalize the external ones. In order to do this, he can use the tools of cognitive mediation between the student and the simulation model. Examples of such tools are: ● Verbal language, to give explanations, compare ideas, and make decisions. ● Images and animations, to visually represent the change of a system over time. ● Causal maps, to describe the cause–effect relation- ship among the variables. ● Graphs and diagrams, to study the time-related behavior of the variables. In order to favor reflection and self-regulation in the learning process, educational techniques such as the following can be used: ● Self-explanation (the student has to explain to him out loud what he has understood) ● Forecasting (the student must foresee what will hap- pen in the next step of the simulation) ● Alternation of observation-practice activities carried out in pairs (the students have to work in pairs and, in turn, one of them performs the simulation while the other one observes) In order to evaluate the change in the mental models of the student within simulation-based learning environments, many different approaches have been suggested based on the think-aloud method, cognitive task analysis, concept maps, Bayesian networks, or on the automated analysis of textual data (Shute et al. 2009). Important Scientific Research and Open Questions Some questions about the design and use of simulation-based learning environments are directly related to fundamental issues in the cognitive sciences. Significant cognitive science research supports the hypothesis that simulation is a fundamental form of computation in the human brain, and this capability of simulation could be the basis of many capabilities: from perception to memory, from language to problem-solving (Barsalou 2008). Mental simulation is a type of reasoning based on the manipulation of a mental model “in the mind’s eye.” It can be part of everyday reasoning, such as when we have to decide how to move a sofa from one room to the next, or be used by scientists to carry out “thought experiments” (Trickett and Trafton 2007). According to Nersessian (1999), simulative modeling is a form of model-based reasoning that includes mental models that are dynamical in nature, whereas analogical modeling and visual modeling may employ static representations. Mental simulations ostensibly imply the reactivation of patterns of neuronal activity in the perceptive and motor parts of the brain initially activated by the direct experience of the event and are therefore also called “perceptual simulations.” The representations involved are in this case of a “modal” type as they preserve the information relative to the modalities through which their external referents were experienced. For this reason, a promising research field is that of the role of perceptual factors in the use of simulations and on the relationship between imagistic simulations, as used by experts and scientists in their thought experiments and the type of visualizations used in simulation-based learning environments to represent the simulated processes (Clement 2009). Abstract concepts can be represented by spatial and kinesthetic structures, known in cognitive semantics as “image-schemas.” For example, imageschemas of concepts such as “expansion” and “compression” can play a role in the construction of mental models of physical or biological phenomena supported by the simulation (Craig et al. 2002). Perceptual factors of this nature can be manipulated through stories, diagrams, and animations, or utilizing new interfaces based on force-feedback devices and visuohaptic technologies. Mental simulation is also one of the possible mechanisms at the base of the “Theory of Mind” (ToM), the ordinary ability people have to understand their own minds and those of others. Two contrasting arguments have been suggested to explain this ability. In the “Theory-Theory” perspective, the ToM is seen as a naive theory (Folk psychology) with posits, axioms, and rules of inferences. The “Simulation Theory” (Gordon 2009), on the other hand, posits that man uses his own mental resources to simulate the psychological causes of others’ behavior by means of role taking, that is, by “putting oneself in the other’s place.” The term “simulation” in this case is used to denote automatic mirroring responses such as the subliminal mimicry of facial expressions and bodily movements (“lowlevel” simulation) or the use of one’s own behavior Simulation of Dynamic Systems control system as a manipulable model to predict and anticipate the behavior of others (“high-level” simulation), in analogy with scientific simulation. However, mental simulation shows clear limits, the most important being that it relies on qualitative relations rather than on precise numerical representation. In simulative reasoning, the inferences derive from the use of the knowledge embedded in the constraints of a mental model to produce new states of the model. Where the situations are more distant from sensorial experience, there are fewer guarantees that the simulation process will yield success. This is particularly evident in the case of nonlinear and self-organizing systems, where also very simple equations or rules can determine complex and unforeseeable behaviors. For example, by observing the causal map of a system with feedback circuits, it is not possible to infer the timerelated behavior of the system. Only computer-based simulation manages to show these behaviors, sometimes counterintuitive or unexpected also for those who built the model. The other limit of mental simulation is that it cannot be shared with others. The building of computer-based simulation models can be useful in this case too, through the shifting from implicit metal models to explicit conceptual ones. Simulation models can thus extend our biological capacity to carry out mental simulations and simulative reasoning. Between student and simulation, a form of “cognitive partnering” can then be set up, where the mental and the conceptual models modify each other in real time, a circular interaction thanks to which the computer can become a real tool for thinking.

BLANCHARD Department of Computer Science and Operational Research, University of Montréal, Montréal, QC, Canada Synonyms Learning with games; Similarity learning; Simulation and learning; Spatial learning; Visual perception learning Definition The term “simulation-based learning” refers to the use of simulation(s) for learning purposes. Definitions for the two parts of this term, i.e., “learning” and “simulation,” are provided in the following paragraphs. Learning is a complex topic as illustrated by the variety of entries in the current encyclopedia. A broad definition is adopted in the current entry with learning defined as the process of acquiring or enhancing knowledge and skills, whether they are cognitive, physical, social, etc. Simulations have been used in many if not all scientific disciplines, which has led to a variety of definitions sometimes reflecting influences and considerations of a specific discipline. For instance, some researchers suggest that simulations are necessarily related to computers. However simulations have emerged ways before the eve of computers’ age; to some extent, the old Chinese game of GO can be seen as a war simulation. Other researchers such as Aldrich (2009) conceive that simulations’ primary goal is oriented toward a learning purpose. Even though the current entry aims at discussing simulations for learning purposes, it will be later shown that simulations whose goal is not primary educational can also provide indirect support to learning, as illustrative elements for instance. Indeed, it would not be adequate to refer to a definition that would not consider the learning potential of simulations that aim at establishing theoretical proofs, or at representing natural phenomena to cite but a few. Hartmann’s (1996) definition of simulation is an interesting step toward a generic definition of this concept. He states that “a simulation imitates one process by another process.” A key aspect of this definition lies in the temporal nature of simulations since processes that he refers to are perceived as elements that evolve over time. Yet some controversies remain on the very idea of considering all simulations as genuinely dynamic. Hughes (1999, see also Grüne-Yanoff and Weirich 2010) insists that simulations sometimes mainly focus on the imitation of the structural aspects of a model rather than on its dynamic characteristics, thus making such simulations relatively static elements. Another noticeable feature for stressing the genuine nature of the simulation concept emerges from the previous point: a simulation is a manifestation of a model, the latter referring to a set of intertwined elements (such as rules, properties, or lower-order models for instances) providing a description of a target. Grüne-Yanoff and Weirich (2010), however, state that there is not always a clear-cut distinction between a model and its associated simulation. Accordingly, in this entry, simulating is defined as the action of imitating a model’s dynamics and/or structure with its resulting element, i.e., a simulation possibly including static and/or dynamic features. Several kinds of simulations exist and can contribute to learning activities at different levels, in a direct manner (as the primary educational element) or in an indirect one (as an illustration or as a positive sidefeature of the learning objective). It is also worth noticing that game-based learning is frequently linked with simulations: business games are a very popular way to teach various aspects of economy, business, and management for instance. However it is important to note Simulation-Based Learning that there exist games that are not based on simulations and simulations that are not games. Theoretical Background Simulation-based learning can occur in two ways: (a) through observation, the simulation thus being an illustration of the content to be learned or understood, or (b) through experiential learning induced by direct interactions with the simulation. Specific characteristics of a given simulation can make the former, the latter, or both learning approaches possible. Furthermore simulations have been applied in various context that shape their inner properties and objectives. For instance, simulations have been used: ● In human and social sciences to understand civili- ● ● ● ● ● ● ● ● zations and represent their past, present, and future evolutions, or to study social phenomena In natural sciences to illustrate behaviors of complex systems such as societies of insects or swarms of birds, or to study the impact of a specific phenomenon on an ecosystem In cognitive sciences to analyze intertwined mental processes at stake within the mind of individual human beings In medicine to represent virtual patients that would express symptoms of a specific illness In chemistry and pharmacology to analyze pros and cons of interactions between molecules In physics to test theories and apparatus addressing atomic to cosmological issues In engineering to test structures and mechanics, and ensure their efficiency and safety In business, management, economy, and finance to deal with processes occurring at the micro or macro level through actors of economical systems In videogames as virtual worlds where a game occurs that could possibly be populated by simulated inhabitants Several features have been discussed in the literature to classify simulations, and influence simulation-based learning opportunities. Realization A same model (i.e., a set of rules and constraints) can lead to differently realized simulations. Three main realization classes can be distinguished: (a) simulations S 3077 involving humans, (b) mechanical simulations, and (c) computer simulations. (a) The business simulation game is a well-known example of simulation involving humans. It is a learning practice where (teams of) students act as if they were in charge of a real business. They may have to deal with stocks, to negotiate with suppliers in order to get the best deals to purchase goods, to compete with other teams of students that run companies with similar objectives, and so on. Similarly, virtual patient simulations have been used in medical education for years. Medical students confronted to trained actors playing the role of a patient with a specific disease can learn the proper way to detect and cure the targeted disease. One of the learning interests of humanbased simulations lies in the genuine adaptive skills of trained human beings who are able to develop coherent and realistic decision making in unplanned situations. (b) Mechanical simulations refer to the use of artificial apparatus to reproduce natural (waves for instance) or artificial (machines for instance) phenomena or systems. Some mechanical simulations such as professional flight simulators can simulate physical sensations that students could experience during the real activity. Among other things, mechanical simulations have been extensively used as reproductions of complex, costly, and dangerous systems such as spacecrafts, or airplanes, thus providing situated, secured, and safe learning environments for people who will have to maneuver them. (c) Computers are frequently used to process and display models related to various aspects of life, with equation-based and agent-based simulations being the two main branches of computer simulations. As pointed out by Neumann (2010), in equationbased simulations, a centralized approach is adopted that implies to have a clear a priori theory about the phenomenon to be simulated so that all its characteristics are transcribed into a system of equations. In agent-based simulations, effects, knowledge, and decision-making abilities are described and distributed among several entities known as agents. Hence characteristics of the global phenomenon are not known a priori but S 3078 S Simulation-Based Learning will emerge from interactions between the different entities. Several computer simulations also have both equation-based and agent-based characteristics. Computer simulations nowadays benefit of the steady computing power progression, which allows an always greater amount of information to be considered at the same time and lead to simulated result closer to reality. Each kind of realization has specific interests for learning purpose, such as the ability to adapt to unpredicted situations, to reproduce physical experiences, or to deal with models that require lots of information. More and more hybrid solutions are developed to combine various positive properties. For instance, professional flight simulators use computers to display cockpit views and to transcribe pilot actions into commands to a “six degrees of freedom” motion platform that reproduce physical changes (cockpit inclinations). A human simulator officer is also frequently in charge of the simulation and can trigger events such as material failures that could strengthen the learning experience. Fidelity Simulations can be characterized on a continuum going from low to high fidelity. Fidelity refers to the extent to which the model correctly represents the element it is supposed to illustrate. From a learning point of view, high and low fidelity simulations each have pros and cons. High fidelity simulations more coherently represent the content to be learned, which results in a limited deformation between this content and the simulated counterpart that the learner is dealing with. Still, high fidelity simulations do not always provide the best pedagogical opportunities since many potentially nonrelevant details may have been modeled that may distract learners from learning objectives or just reveal too complex for their current understanding abilities. Hence, a lower fidelity simulation that would focus only on pedagogically relevant aspects of the domain to be learned is sometimes more adequate, especially for beginners that have to deal with lots of novel information. However lower fidelity is not necessary due only to an incomplete model, and fantasy elements may have been added (Hollan et al. 1987). While they might raise the fun level of a simulation serious game, and improve the users’ motivation, fantasy elements can also corrupt the learning message and confuse learners who could hardly distinguish true learning information from a fantasized one. Interactivity Interactivity refers to the possibility for users not only to be passive observers of the simulation, but also to act on it and to influence its evolution. Simulations can be interactive in different ways. The user could for instance have the possibility to modify simulation parameters, and learning would result from observations of changes induced by these modifications. Another possibility is to have the user directly involved in the simulation, as an inner actor that could even have its representation, frequently referred to as “avatar.” Hence the user would directly interact with characteristics of the simulated phenomenon, and could then extrapolate some experiential learning. Constraints sometimes reduce interactivity. For instance, navigating from one location to another in a virtual world is sometimes restricted to a limited set of paths. But in other virtual worlds, freedom of movement is total. Such world simulations are sometimes labeled as “open world.” Depending on the case, constraints can be perceived as guidance or as restrictions. Interactivity can be beneficial to simulation-based learning because it is an efficient way of promoting motivation for an activity. As such, it can influence learners’ perseverance in the activity and their willingness to reuse the simulation-based learning system in the future. Simulations can also propose interactive ways to answer to learners’ needs of guidance and explanations. However interactive techniques can also distract learners from their objectives when they are not used with caution. Immersiveness Virtual environments sometimes provide rendering fidelity and accuracy in simulated behaviors, particularly if they are delivered with features that trigger immersive feelings. This frequently results in a better perception and more adequate reactions. In addition, pedagogical capabilities can be incorporated into autonomous agents (Johnson et al. 1998). CAVEs Simulation-Based Learning (cave automatic virtual environment) are specific immersive virtual reality environments where several projectors are oriented to a curved screen (concave wall) or to a cube (three to six walls). In such a setting the user is thus located in the center of a fully immersive environment with high-resolution projectors displaying images on each screen. Sometimes images are projected onto mirrors to reflect the images onto the projection screens, reducing the space required for the CAVE. Using stereoscopic glasses, images are separated for each user’s eye that can see 3D stereoscopic objects floating in the air. Users can evolve around these objects with a dynamic tracking of their positions which increases the interaction and simulation between user and environment. They learn rapidly how to set up, improve, and test the environment. The major advantage is that various prototypes (car, plane, building) or interfaces can be developed and tested, without spending any money on industrial development of the complete environment. Reactions of both the environment and the user into the environment can be tested in advance. Intelligence Simulation-based learning can also be enhanced by intelligent components such as intelligent agents (Lester et al. 1999) that are able to react to user’s interaction and to propose various constructive alternatives such as counterexamples, corrections to the manipulation, or guidance toward correct gestures and actions. In addition, the system can react intelligently to user’s interactions in order to progressively present new decision situations. This is particularly important for instance in medicine where specific emergency situations can be created, in military strategic cases in which correct decisions must be taken, in aeronautics, fire-fighters training, and other situations which require a decision-making process. Simulation environments can be enhanced by life-like animated agents such as Cosmo (Lester et al. 1999) that provides customized advices to support students’ problem solving. A key problem posed by these life-like agents that inhabit artificial worlds is deictic believability and for that they have to move through their environment, pointing judiciously to objects as they provide problem-solving advice. These types of simulations have a strong contribution to learning. S 3079 Important Scientific Research and Open Questions Simulation-based learning should increase in the future resulting from improvements of technology and software. Important questions remain such as what is the impact of virtual reality environments on human behavior and decisions? Visualization process is more and more important and a particular effort is driven on facilities to produce a simulation. To increase the realism of simulation (believability), affective considerations begin to be introduced and tested with affective agents or avatars. They mimic emotional reactions, an important part of human behavior. Several works are under way on this topic. Other research is focusing on the introduction of learning through a large variety of games (funny games, 3D real time game of strategy and adventure). As it becomes more easy and funny to learn through these subtleties a lot of work try to investigate ways to introduce learning into games or games into learning programs. Other works are focusing on the introduction of intelligence into games. This can take into consideration the learning style or the motivation of the learner, but also several cognitive components such as attention, focus, speed, spatial reasoning, problem solving, stress, or reaction time. This aspect of intelligence means that the game should adapt to each user not only at the beginning of the game but also dynamically along the game.

Simulator Model ▶ Computer Simulation Model Simultaneous Discrimination Learning in Animals THOMAS R. ZENTALL Department of Psychology, University of Kentucky, Lexington, KY, USA Synonyms Contrast; Difference; Distinction Definition In a simultaneous discrimination, two (or more) stimuli are presented simultaneously, and only one is correct ((the S+) and choice of it is reinforced). Choice of the other(s) (the S) is not. In a successive discrimination, two (or more) stimuli are presented successively, and responses to one are reinforced whereas responses to the other are not. Of particular interest is the effect that one stimulus has on the other. Theoretical Background Psychologists have been studying instrumental discrimination learning in animals systematically for almost 100 years. In most cases, two stimuli are presented, and choice of one (often referred to as the S plus or S+) is correct (reinforced), whereas choice of the other (often referred to as the S minus or S) is not. In the case of successive discriminations, each stimulus is presented individually, and the measure of discrimination learning is typically the ratio of responses to the S+ relative to total responses to both the S+ and the S (often referred to as the discrimination ratio), whereas with simultaneous discriminations, both stimuli are presented together, a choice is made between them, and the measure of discrimination learning is generally the proportion or percentage of choices of the S+. There are two forms of stimulus interactions that should be distinguished. The first is based on the properties of the stimuli themselves (the similarity between them). The more similar the stimuli to be discriminated, the more difficult it is to learn the discrimination. The second is based on the properties of the procedure. When stimuli are presented simultaneously, what is learned about one may affect the other because it is present at the same time. Most of the research on discrimination learning that has been published in the past 50 years has used a successive discrimination procedure, perhaps because it is simpler (only one stimulus is presented at a time) and, consequently, it is easier to interpret the meaning of the rate of responding to the stimuli. However, recent research using simultaneous discrimination procedures suggests that the stimulus interactions that occur with this procedure may be quite different from those that occur when discriminations are acquired by successive procedures. In successive discriminations, the effect that one stimulus has on the other is generally described as contrast. That is, if an S+ stimulus is alternated with an S stimulus, the tendency to respond to the S+ stimulus is generally greater than if both of the stimuli are S+ stimuli. This is known as positive contrast. Similarly, if two S+ stimuli are alternated and if one of them improves in value, responding to the other tends to decrease. This is known as negative contrast. In other words, one of the stimuli appears to be valued relative to the other and the better one makes the poorer one appear worse, while the poorer one makes the better one appear even better. Simultaneous Discrimination Learning in Animals According to traditional theories of discrimination learning (e.g., Spence 1937), successive and simultaneous discriminations should involve similar learning. Research has shown, however, that in simultaneous discriminations, the effect that one stimulus has on the other is likely to be more complex. That is, it may increase or decrease the value of the other depending on the experiences the animal has had with each. Important Scientific Research and Open Questions Major strides in understanding stimulus interactions in simultaneous discriminations have been made in the past 20 years. The process began with Fersen, Wynne, Delius, and Staddon’s (1991) suggestion that in a simultaneous discrimination, some of the value associated with the S+ transfers (or generalizes) to the S that is presented with it (an induction-like process) such that the S+ increases the value of S with which it was paired. If the notion of value transfer in a simultaneous discrimination is correct, it would suggest that stimulus interactions in simultaneous discriminations are opposite to the contrast effects typically found in successive discriminations. A direct test of value transfer in simultaneous discriminations was conducted by Zentall and Sherburne (1994). In one discrimination, A100B0, responses to A were reinforced on all trials, whereas responses to B were never reinforced. In the other discrimination, C50D0, responses to C were reinforced on 50% of the trials, whereas responses to D were never reinforced. On test trials, when the pigeons were tested with B and D, they almost always preferred B over D. Thus, A appeared to give more value to B than C could give to D, evidence for value transfer. An important difference between the successive and simultaneous procedures is the experience that the animals have with the S stimuli. With the successive procedure, the S stimulus is presented by itself so the animal has ample opportunity to learn about the consequences responding to it. In the simultaneous procedure, however, the animal quickly learns that the S+ is the better of the two stimuli, and it does not learn as much about value of the S stimulus. Clement and Zentall (2000) asked if that could explain the difference in results between the two procedures. To test this hypothesis, Clement and Zentall trained pigeons with A100B0 and C50D0, but they included presentations of S 3081 each of the two S stimuli, B0 and D0, alone. In this case, on test trials, when they gave the pigeons a choice between B and D, the pigeons showed a strong preference for D, evidence for contrast. Thus, it appears that the effect that the stimuli in a simultaneous discrimination have on each other depends on the kinds of experiences that have been had with the S stimulus. Under typical simultaneous discrimination conditions in which there is little experience with the S stimulus because learning is quite rapid, there appears to be little opportunity to build up inhibition to or avoidance of the S stimulus and value will transfer from the S+ to the S. However, if inhibition is allowed to build up because of extended experience with the consequences of responding to the S stimulus, it should result in contrast, resulting in both an increase in the relative value of the S+ with which it appears and a decrease in the relative value of the S itself. That is, extended experience with the S stimulus in a simultaneous discrimination effectively converts a simultaneous discrimination into a successive discrimination. An interesting parallel can sometimes be seen in human social contexts. If one is introduced to the friend of a friend, one tends to ascribe some of the attributes of one’s friend to the new person (value transfer). Once one gets to know the new person, however, one is more likely to compare the two individuals and focus on their differences (contrast).

Situated Cognition MURAT ATAIZI Department of Communication, School of Communication, Anadolu University, Eskisehir, Turkey Synonyms Anchored instruction; Cognitive approach; Communities of practice; Situated learning Definition Humans are socially curious beings and learn mostly through social interaction with others. This social interaction involves context, culture, activity, discourse, people, and so on. Situated cognition is the study of human learning that takes place when someone is doing something in both the real and virtual world, and therefore learning occurs in a situated activity that has social, cultural, and physical contexts. Theoretical Background Situated cognition is a theoretical approach to human learning that supports the idea that learning takes place when an individual is doing something. Situated cognition has been positioned as an alternative to information processing theory. Situated cognition theory promises to complete the symbolic-computation approach to cognition, as information processing theory neglects conscious reasoning and thought (Wilson and Myers 2000). Researchers are divided into two camps of situated cognition theory: 1. Anthropologists like Jean Lave (1988, 1991) and Lucy Suchman (1993) are interested in the cultural construction of meaning. These anthropologists combine anthropology and critical theory with the socioculturalism of Vygotsky. 2. Allan Collins, John Seeley Brown, Don Norman, and Bill Clancey are interested in cognition at individual and social levels. According to these researchers, situated cognition has strong links to artificial intelligence, neuroscience, linguistics, and psychology due to their focus on understanding the individual mind (pp. 65–66). Another viewpoint on situated cognition comes from Kirshner and Whitson (1997). They analyze situated cognition as a research approach that relates social, behavioral, psychological, and neural perspectives of knowledge and action in their edited collection of chapters on situated cognition. The contributors examine the problems of situated cognition using conceptual resources from a broader range of social theory. They emphasize theories such as situated cognition theory, situativity theory, and other positions that seek to better reflect the fundamentally social nature of learning and cognition and provide new opportunities to reorient and perhaps redesign education. In the field of educational psychology, situated cognition gained researchers’ attention in late twentieth century. In the early 1980s, the Soviet scientist Lev Vygotsky and his colleagues and students became interested in studying human cognitive capabilities, and in this context they focused on scientific thinking. “Learning by doing” became the key concept in the field of learning and education at this time. Brown, Collins, and Duguid were adapters of this concept in the field of education (1989). Jean Lave and Etienne Wenger (1991) came to situated learning and cognition from the anthropological perspective of communities of practice. Clancey (1997) studied the changing design of intelligent machines and examined the implications of situated action from the perspective of artificial intelligence scientists interested in building robots and seeking to relate descriptive models to neural and social views of language. Clancey (1997) posits that situated cognition developed not as a discipline within artificial intelligence or psychology or educational technology but as a way of thinking by the some of the well-known scientists of the twentieth century in psychology, biology, sociology, psychiatry, and philosophy. He states that situated cognition is the study of how human knowledge develops as a means of Situated Cognition coordinating activity within activity itself. The meaning of this explanation is that feedback is very important because it is occurring internally and within the environment over time. Therefore, knowledge has a dynamic aspect in both formation and content. This is a shift from knowledge as stored artifact to knowledge as constructed capability in action (p. 4). According to this assumption, learning occurs through feedback inside and outside the brain, but this is not a simple process because people do not simply make plans and then do things. They continuously adjust and invent. Managing this process means managing learning, not managing application (Clancey 1995, p. 39). Gee (1997) focuses on construction of meaning and on thinking from a sociocultural approach. Here, construction of meaning is related to the specific context and purpose. Learning certain types of patterns and futures in a particular context requires a special culture; Gee calls this type of cultural interaction “discourses.” “Discourses are sociohistorical coordinations of people, objects (props), ways of talking, acting, interacting, thinking, valuing and (sometimes) writing and reading that allow for the display and recognition of socially significant identities like being a (certain sort of) African American, Turkish worker in Germany, lawyer, street-gang member, schoolchild, teacher, feminist and so on” (pp. 255–256). Discourses help people to exchange thoughts and explanations. “If you destroy a Discourse (and they do die), you also destroy its cultural models, situated meanings, and its concomitant identities” (p. 256). Therefore, discourse plays a vital role in human learning and cultural development when looking from a situated cognition perspective. New research on situated cognition theory focus on communities of practice, online communities, and artificial intelligence with instructional design practices since discourse focuses attention on human learning. Important Scientific Research and Open Questions Both cognitivism and behaviorism explain learning and knowledge as resulting from human experience in the objective world. According to these theories, the world is a stable place where human knowledge and values are objective. Learning and knowledge are not created in an individual’s thoughts, but are determined by the nature of reality in the objective world. S 3083 According to Kirshner and Whitson (1997), these objective limitations and stability create dissatisfaction among educators, anthropologists, psychologists, and social theorists. They focus on the opportunity to explore learning and knowledge as processes that occur in a local, subjective, and socially constructed world that is dreadfully limited by both behaviorist and cognitivist approaches (p. vii, viii). Situated cognition theory loses some of its potential to inspire in the arena of education if it is not connected with real-world situations by instructional design activities. The work of the Cognition and Technology Group at Vanderbilt University is a good example of anchored instruction that has close relation to the situated learning approach and situated cognition theory. The goal of anchored instruction is to create technology-rich learning environments with video to help learners to solve authentic, real-world problems. The students first identify a problem situation through a collaborative problem formulation and then solve the problem with their team. Research on situated cognition theory takes place mostly in real-world settings and, therefore, mixed methods and qualitative approaches are used by researchers. The application of this theory into practice has great promise for current and future learning. The next step for situated cognition theorists is to develop new, innovative models to explore knowledge and learning as fundamentally more social and cultural, rather than objective and stable, and to connect these models with practice to create worthwhile learning environments, both virtual and real.

Situated Learning MURAT ATAIZI School of Communication, Department of Communication, Anadolu University, Eskisehir, Turkey Synonyms Cognitive apprenticeship; Communities of practice; Situated cognition Definition Humans are socially curious beings and learn mostly through social interaction with others. Learning does not take place in an individuals’ mind, it is situated in a context in which participation of individuals to the communities of practice plays a vital role on situated learning process. Situated learning occurs generally when an individual is not intended or planned to learn. Participation and doing take main place in situated learning. Situated learning take place when learning is specific to the situation in which it is learned. Theoretical Background Jean Lave and Etienne Wenger are the first presenters of situated learning, and they argue that learning is situated in certain forms of social coparticipation rather than asking what kinds of cognitive processes and conceptual structures are involved during the learning processes. They paraphrase learning as a social engagements in a specific context in which learning takes place (p.14. Lave and Wenger 1991). The important point here is that learning is not an individual mind process, as explained in classical intellectualist theory that the individual acquires mastery over the processes of reasoning and description, by internalizing and manipulating structures (p.15), whereas Lave and Wenger argue that the learning takes place when an individual participates in communities of practice, and learning is distributed among participants of those communities. In their view, learning is an integral part of generative social practice in the lived-in world. Learning can be explored as legitimate peripheral participation. When a person become into communities of practice gradually transformed into practitioner, a newcomer becoming old-timer, a member of a community of practice in which all the task, skills, and knowledge can be learned. Brown et al. (1989) focus on school learning and explaining that the conventional school learning influenced by the culture of school. They are remarking coherent, meaningful, and purposeful activities as authentic activities and expressing that these activities are not seen and found much in conventional schooling systems. According to them, authentic activities simply defined as the ordinary practices of the culture (p.34). Authentic activities are very important for learners because it is the only way to gain access to the standpoint of practitioners. As a part of situated learning model, Brown et al. (1989) added “JPFs” – Just Plain Folks – beside the concepts of students and practitioners. The JPFs shows some similarities during reasoning with the expert rather than the students. The students reason with Laws with the influence of school culture but the JPFs reason with casual stories and the practitioners reason with casual models. In a normal daily life when JPFs desire to learn a particular set of practice, they have two options. The first option is Situated Learning enculturation through apprenticeship. For instance, craft apprentices acquire and develop knowledge by apprenticeship in real-world environments all the time. The apprentices’ behavior and the JPFs’ behavior are very similar in this sense. The second option is to enter into a school as a student. The school setting is pretty much different than the outside world. School activities are much consists of precise, well-defined problems, formal definitions, and symbol manipulations (p.35). The students themselves can acquire and develop knowledge by the help of teachers and coaches in the school settings. They are also remarking the idea of cognitive apprenticeship. Cognitive apprenticeship claims that social interaction and social construction of knowledge improve learning both inside and outside of the school. Cognitive apprenticeship methods try to enculturate students into authentic practices through activity and social interaction that are similar with the craft apprentices’ acquiring and developing knowledge by apprenticeship in real world environments. McLennan (1996) arranged and published a situated learning model based upon the notion that knowledge is contextually situated and is fundamentally influenced by the activity, context, and culture in which it is used (Brown et al. 1989). The key components of the situated learning model are: 1. 2. 3. 4. 5. 6. 7. 8. Stories Reflection Cognitive apprenticeship Collaboration Coaching Multiple practice Articulation of learning skills Technology 1. Stories are playing a very important role for situated learning and for the social construction of knowledge because they help people keep track of their discoveries. Also, stories provide a meaningful structure of remembering for what has been learned before. 2. Reflection is another significantly important component of situated learning. Norman (1993) expresses that there is reflective and experiential cognition of human being. The experiential thinking is faster and immediate, but the reflective thinking is deeper. Situated learning combines both reflective and experiential cognition in the communities of practice. S 3. Cognitive apprenticeship is the other element of situated learning model. Brown et al. (1989) propose the concept of cognitive apprenticeship. “Cognitive apprenticeship methods try to enculturate students into authentic practices through activity and social interaction in a way similar to that evident-in craft apprenticeship (p.37).” 4. Collaboration is another vital element of situated learning model. Brown et al. (1989) proposed the four major features of collaborative learning: (1) collective problem solving, (2) displaying multiple roles, (3) confronting ineffective strategies and misconceptions, and (4) providing collaborative work skills. 5. Coaching plays central role between cognitive apprenticeship and situated learning. Coaching consists of observing and supporting students while they are practicing and learning in collaboration. Coaching also provides scaffolding for learning whenever and wherever necessary. 6. Articulation encloses two aspects. The first aspect is the concept of separating or articulating different component skills in order to learn them more effectively. Second, articulation refers the goal of getting students to articulate their knowledge, reasoning, or problem-solving processes in a domain (McLennan 1996, p. 12). 7. Technology today plays vital and core role to support and create situated-learning environments and also contributes for enhancing reflective thinking of students. The most well-known multimedia program that produced by The Cognition and Technology Group at Vanderbilt is an example of technology supported situated-learning application. The situated-learning model is a good guide for instructional designers to create effective situatedlearning environments. Important Scientific Research and Open Questions Situated-learning environments like Algebra Project, the work of the Cognition and Technology Group at Vanderbilt University, Shoenfeld’s approach to teaching mathematics, the Foxfire Project, and other new situated-learning projects both online and offline suggest that situated learning has great promise for learning needs for today and tomorrow. In this regard, 3085 S 3086 S Situated Prompts in Authentic Learning Environments situated learning and instructional design areas need to develop better mixed learning environments to consider the situated-learning model. A great deal of work is needed to a fine-tune theory and assess how to transform this theory into practice McLennan (1996). Winn (1996) debates that instructional design assumes that what people learn is relatively stable across the situations in which it is used and that people apply what they have learned in logical and planned ways. Since situated-learning remarks that human action is independent on the context in which it occurs, it is impossible to foresee every situation when designing instruction. Therefore, it is impossible to design instruction that can prepare students to act appropriately in all situations (p. 59). Arguments show that situated learning and instructional design have some discrepancies in their point of view to learning, but innovative learning environments can be designed by the help of multiple perspectives of both theories and researchers.

Situated Prompts in Authentic Learning Environments HOLGER HORZ Department of Psychology, Educational Psychology and Head of Interdisciplinary College of University Didactics, Johann Wolfgang Goethe-University, Frankfurt, Germany Synonyms Computer-supported learning; Instructional help; Instructional support; Prompting; Situated learning Definition Prompts Prompts are messages on a computer screen that require users to react in a specific way. Prompts are commonly used in computer-based learning environments to enable learning processes and to dint of provide instructional support. Authentic Computer-Based Learning Environment A computer-based learning environment is called authentic if learners use learning environments to simulate realistic contexts that reflect the way the knowledge will be used in real life. Situated Prompts Situated prompts are embedded in the realistic context of learning environments so that learners do not perceive them as “additional” instructions but rather as an integral part of the authentic learning environments’ scenario. Cognitive Load It is assumed that learning is associated with cognitive load in working memory, which has a limited capacity. It is important for effective learning that cognitive load triggered by learning materials is not higher than the available working memory capacity. Theoretical Background A main point of criticism concerning school and university learning is the separation between knowing and Situated Prompts in Authentic Learning Environments doing something. This separation may lead to “inert” knowledge where learners can express the learned information but cannot use it. Brown et al. (1989) argue that authentic activities of learners are necessary to acquire the active use of a domain’s competencies. This idea led to the theory of situated learning, which proposes that learning should happen in contexts reflecting a useful or meaningful way to apply acquired knowledge and competencies in real life. However, a well-known problem is a lack of regular classrooms’ appropriateness to create authentic learning environments. A possible solution may be computer-based authentic learning environments, which simulate real-life tasks as an incentive for learning. The theoretical assumption is that computer-based authentic learning environments offer opportunities to apply acquired theoretical knowledge to real life tasks and, by doing so, prevent inert knowledge. Although computer-based authentic learning environments are not full-fledged substitutes of experiences, which learners could have made in praxis, it is widely accepted that these environments are a useful alternative to real-life setting. Computer-based learning environments (1) allow integration of different authentic media, (2) make authentic adaptive interactive trainings more likely than other media, and (3) facilitate the simulation of realistic complex relations between different objects in a learning environment. Nearly all kinds of learning environments use instructional support to enhance the learning processes. The rationale behind integrating instructional support is to offer assistance which can be used when needed. Following the approach of computer-based authentic learning environments, not only the learning content should be situated and embedded in the learning context, but additional instructions should be linked to the demands of the specific task in the learning situation as well. In addition to the positive effects of situated learning in general, it is assumed that situating instructional support (e.g., by prompts) will reduce appearance probability of insufficient use of instructional support in computer-based learning environments. Because learners often perceive instructional support as “additional” or “less important” (meaning not required), a well-designed and adequate situated prompt (or other kinds of presenting situated instructional support) will reduce such counterproductive impressions of instructional support. S 3087 However, integrating situated prompts may further raise cognitive demands on learners. It leads to an authenticity increase of a learning environment, which predominantly causes a higher learning environments’ complexity because of integrating additional non-essential information. Therefore, as a product of cognitive activities in the working memory (Sweller, van Merriënboer, and Paas 1998), a higher cognitive load results from learning with authentic learning environments compared to learning environment without any added information to enhance the learning environments’ authenticity. Situated prompts may hamper their positive effects with respect to the learning outcome. This is because of restricted processing capacity of human mind, especially if learning time is limited (van Merriënboer et al. 2006). In that case, learners will not manage all affordances of an authentic learning environments and its situated prompts because the cognitive load is simply too high (cognitive overload). As a result, learning efficiency diminishes because of increasing learning time and learners’ limited endurance. Important Scientific Research and Open Questions The assumption about positive effects of computerbased authentic learning environments and situated prompts in terms of learners’ acquisition of more elaborated and active knowledge is empirically supported (Cognition & Technology Group at Vanderbilt 1993). However, it is even empirically demonstrated that enhancing authenticity of computer-based learning environments or integrating situated prompts to prevent inert knowledge (Horz et al. 2009) imposes high regulatory demands on learners and may hamper their learning outcomes. Different factors are identified, influencing the effectivity of computer-based authentic learning environments and/or instructional support like situated prompts. A review by Clarebout and Elen (2006) showed that the type of support device plays an important role. First, learners mainly use instructional support that delivers additional information, while support devices aimed at supporting metacognitive skills by inviting students to reflect on their activities were seldom used. Second, learners’ prior knowledge influences the use of instructional support. S 3088 S Situated Prompts in Authentic Learning Environments Learners with low domain and/or low computer knowledge may be overwhelmed by task complexity in computer-based authentic learning environments and become uncertain how to deal with them. This often leads to disorientation problems (“lost in hyperspace”; see Dillon and Gabbard 1998) so that the learning achievement may be disrupted, resulting in worse learning outcomes. One possibility to solve these problems is to integrate situated instructions in learning environments by the use of prompts. Because of learners’ limited cognitive resources in the working memory, any evaluation of an authentic learning environment should also take into account the potential interactions between the support type and individual learners’ prerequisites (aptitude–treatment interactions). The proper cognitive resource allocation is critical to learning, if learners are requested to devote mental resources to activities not directly linked to information processing and integration of knowledge. In this way, the learning process may be disturbed (Sweller, van Merriënboer, and Paas 1998). In complex learning environments learners with low prior knowledge show mostly a reduced learning success compared to learners with high prior knowledge. When learners with low prior knowledge encounter problems while working with a computer-based authentic learning environment, they are probably unable to increase their already high cognitive load any further and process additional support information as presented by situated prompts. They are simply “maxed out” by the additional information and the consequent increasing cognitive load. As a consequence, learning regulation may fail, and the learning outcome may decline as a whole (cf. Horz et al. 2009). Based on the reasoning previously outlined, a dilemma for the implementation of situated instructional prompts arises, which will be a starting point for future research in that field. Situated prompts have to be a part of a fully authentic learning environment, and authenticity leads to a higher cognitive load as outlined above. Situated prompts must be tailored to increase learning outcome of the learner. However, if a learning environment is set up to be fully authentic it must necessarily have some features that are not relevant for the learning task, so that learners get additional information about their role in the learning environments far in excess of the minimum facts, which should be learned. This leads to an ambiguous result. Added features, which are integrated to increase the authenticity, need to be processed by the learners and do increase their cognitive load during learning. In contrast, the added features do support learning activities. As a consequence, these learning environments should be designed in a way that learners become aware of their comprehension failures and use additional information when necessary. Therefore, it is beneficial to increase and facilitate the use of additional information by situated prompts. However, it must be considered that situated prompts may increase cognitive load, especially with learners who have low prior knowledge. These learners tend not benefit from situated prompts. In future, it will be a challenging technological and psychological research issue to find the right and perfectly balanced way in which to add information for a higher authenticity in computer-based learning environments and to regulate added cognitive load of any kind of instructional support.

Skill Learning Situational Interest Situational interest refers to the interestingness of a situation or context; that is, it is generated by the characteristics, conditions, or features of the social and nonsocial environment. Situational interests emerge when the characteristics of an activity, toy, material, person, or event attract a child’s attention, arouse curiosity or surprise, and invite engagement. Situations that have elements of novelty, exploration, or surprise often evoke situational interest. Situational interests are considered to be context-specific and relatively temporary or transient but may develop into more longlasting personal interests.

(1904–1990) FREDERICK TOATES Department of Life Sciences, The Open University, Milton Keynes, UK Life Dates Burrhus Frederic Skinner was born on March 20, 1904, in the small Pennsylvania railroad town of Susquehanna, where he grew up. Known to most as “Fred,” his childhood was characterized by a strong curiosity about the natural world. He spent much time in exploration of nature and in devising gadgets of various sorts, which was to serve him well later. After leaving school, Skinner studied at Hamilton College and, on leaving, decided to become a writer (though only later was this aim realized and in the form of psychology texts). Skinner’s reading of Bertrand Russell and John Watson exerted a profound influence on him in terms of philosophical foundations. At 24 years of age, Skinner became a graduate student in the Psychology Department of Harvard University. He studied the behavior of rats and pigeons and devised a number of laboratory gadgets to facilitate this research. Among these was the apparatus that was later to be called the “Skinner box” and the cumulative recorder, a piece of equipment in which a roll of paper was drawn across a pen. When the rat pressed the lever in the Skinner box or a pigeon pecked the key, a click on the pen was triggered such that a record (“cumulative record”) of the animal’s behavior was formed. In 1936, Skinner married Yvonne Blue and he moved to Minnesota to take up a university teaching position at the University of Minnesota. His first book, entitled The Behavior of Organisms, was published in 1938. During the Second World War, Skinner investigated the possibility of training pigeons to guide missiles. At this time, Skinner also devised a heated crib for his daughter. To hostile commentators, there was confusion between the crib and the Skinner box and unfounded rumors circulated that his daughter had committed suicide. At the end of the war, Skinner embarked on writing a Utopian novel, entitled Walden Two. This described a community of people who shun materialism and punitive means of control, leading a life based upon egalitarianism and mutual positive reinforcement. It was something of a Green proclamation, years before the political notion of “Green” was in vogue. In 1945, Skinner moved to take up the Chair of Psychology at the University of Indiana in Bloomington. A society dedicated to studying behavior within the Skinnerian tradition, termed the Society for the Experimental Analysis of Behavior, was formed and held its first meeting in Indiana in 1946. A journal dedicated to the publication of articles within this tradition, the Journal of the Experimental Analysis of Behavior, first appeared in 1958. Skinner moved back to Harvard University in 1948 to take up a teaching position. In 1953, he published the book Science and Human Behavior, followed in 1957 by Schedules of Reinforcement with Charles Ferster. The year of 1953 saw an important (“epiphany”) moment in Skinner’s life when he attended a class in which his daughter was being taught mathematics. He was struck by the pace of the class, which was too fast for some pupils and too slow for others. Generic feedback, which was given to the whole class, was inevitably delayed relative to each individual pupil’s behavior and often inappropriate to the individual. From this observation, he was moved to devise a teaching machine, in which each pupil paced himself or herself. Feedback was thereby appropriate to each individual pupil and was presented immediately after the response by the pupil. Problems were broken down into small parts so that answers were reinforced before going onto the next question. In 1957, he published his book on language entitled Verbal Behavior, which formed the target of a famous and highly critical review written by Noam Chomsky. Skinner was concerned that behavioral psychology be used to solve human problems on a national and global scale. His conviction was that social problems arise in large part from the failure of public authorities to utilize positive reinforcement and instead to use punitive controls. In 1971, he produced a best seller Skinner, Burrhus F. (1904–1990) entitled Beyond Freedom and Dignity. This argued for abandoning the notion of autonomy and accepting a scientific understanding of human behavior and the principles of reinforcement. The book sparked outrage from many offended individuals including the US Vice President Spiro Agnew. Starting in 1976, Skinner published three volumes of autobiography. In 1989, doctors discovered that Skinner had leukemia. Nonetheless, he carried on working right up to the day of his death, giving a presentation to the American Psychological Association 10 days prior to this. He died on August 18, 1990. Contribution(s) to the Field of Learning In human and nonhuman species, Skinner identified many of the important parameters that determine learning, such as partial reinforcement (a schedule in which only certain responses are reinforced). He was an early advocate of the need to treat each learner as an individual. What might be positively reinforcing for one learner might be punishing to another. That is to say, reinforcement was defined, not in terms of any intrinsic physical properties of reinforcers, but by its effect on behavior. Skinner drew attention to the everpresent process of reinforcement that is often overlooked or denied. For example, viewed within this perspective, teachers need to observe carefully the effects of any interventions in the teaching situation. In teaching, Skinnerian approaches identify hidden and subtle sources of reinforcement. For example, what might intuitively be felt to be punishing (i.e., lowering the probability of the instance of behavior being shown), might, in reality, be positively reinforcing (i.e., increasing the probability of the behavior being shown). Criticism given to bad behavior, though thought to be punishing, might, in reality, be positively reinforcing, via attention seeking. Reinforcers are usually seen to be such things as food, water, and praise. However, behavior itself might exert a reinforcing effect. For example, in smoking cigarettes, the action of smoking might form part of the reinforcement, in addition to any reinforcing component arising from the absorption of nicotine. Intrinsic biological changes might also constitute part of reinforcement, as in the adrenalin surge on engaging in risky activities. It is often suggested that social reinforcers are S 3091 crucially important as in forming part of a social group, as in criminal gangs. Skinner was the inspiration behind using tokens as reinforcers, as in mental hospitals. Patients who were hitherto unresponsive could earn tokens for desired behavior. The tokens would later be exchanged for rewards. Skinnerian psychology acknowledges that some behavior is not the consequence of reinforcement, as in following rules. However, an analysis of behavior can often show where a process of reinforcement produces behavior that acts in opposition to rules and sanctions. Addiction to drugs illustrates the power of such reinforcement. Skinner was a committed humanitarian who campaigned tirelessly against the use of aversive controls of behavior. This was on the grounds of their unethical nature and their relative ineffectiveness as controls of behavior. Skinner’s invention of the teaching machine was an early forerunner of what is now embedded in the much more sophisticated versions that utilize personal computers but the principles of self-pacing and guidance through feedback is the same. Theoretical Background In terms of the specifics of the principles of learning, the intellectual framework for Skinner was provided by the work of Pavlov, Watson, and Thorndike. The theoretical model current at the time of the initiation of his investigation was one described by the term “stimulus-response,” in which an instance of behavior, the response, was said to be triggered by an immediately preceding event, defined as the “stimulus.” Skinner felt that the kind of behavior that he studied in the Skinner box could not be accounted for by such a model. Rather, behavior was more closely associated with the consequence of earlier behavior, i.e., the history of reinforcement. Such behavior, which “operated” upon the environment, was termed “operant behavior.” It is a special case of “instrumental behavior,” the broad class being defined in terms of behavior being instrumental in the outcome, e.g., behavior is instrumental in getting to food in a maze. Where the animal freely paces its own activity, the process of changing behavior by means of the consequences that follow from behavior is known as “operant conditioning.” S 3092 S Sleep or Offline Learning Cross-References ▶ Behaviorism and Behaviorist Learning Theories ▶ Conditioning ▶ Insight Learning or Shaping ▶ Operant Behavior ▶ Thorndike, Edward L.

Social Brain ▶ Machiavellian Intelligence Hypothesis Social Cognition ▶ Learning in the Social Context Social Cognitive Learning EUGENE SUBBOTSKY Department of Psychology, University of Lancaster University – Lancaster University, Lancaster, UK Synonyms Imitation; Observational learning; Social learning Definition Social cognitive learning occurs when an individual learns from other members of the group by observing S 3093 and imitating their behavior. In order to imitate another person an individual has to establish a correspondence between this person’s behavior and that of his or her own, and this requires a certain level of cognitive development. Some researchers argue that certain species of animals, like chimpanzees, are capable of imitation, and human infants are able to do this from the earliest hours following birth, for instance, by imitating their mother’s facial expressions. Theoretical Background Social cognitive learning theory is a theory that aspired to make for the drawbacks of the traditional learning theory based on the concept of classical conditioning (Eysenk 1960; Skinner 1971). According to social learning theorists, learning, particularly in the area of social behavior, cannot be satisfactorily explained by the concept of social reinforcement of new forms of behavior, because it does not explain how these new forms of behavior appear in the child’s behavioral repertoire for the first time. These theorists postulate that certain forms of behavior, such as imitation, are selfreinforced, and therefore children can learn directly from observing other people’s behavior. Bandura and Walters (1964) indeed demonstrated that direct observation of models elicit apparently unconditional imitation in children. The theoretical explanation of this “unconditional” imitation can be found in Mowrer’s (1950) theory of “primary identification.” According to this theorist, primary identification emerges in the first 3 years of life, when the child’s caregivers’ behavior becomes associated in the child’s mind with all sorts of positive emotional experience that the child gets from his or her caregivers in the process of routine interactions, such as feeding, caressing, etc. This association brings in the hidden motive of the apparently “unconditional” imitation: through imitating the caregivers’ behavior, the child reexperiences the pleasant emotions that had been previously associated with the caregivers. The mechanism of “primary identification” can explain the motivational underpinning of learning in both cognitive and moral domains, yet it is limited in regard to the explanation of causes of antisocial behavior in cognitively sophisticated individuals. According to Bandura (1991), the most sophisticated moral thinking and reasoning cannot provide a direct link to moral conduct: Along with creating an invariant control system within a person that prompts the person S 3094 S Social Cognitive Learning to cherish moral values, cognitive development also creates mechanisms by which self-sanctions can be disengaged from antisocial conduct. Bandura (1999) provided a detailed description of those mechanisms, such as moral justification of reprehensive conduct, diffusion of responsibility, minimizing detrimental effects and consequences of immoral acts, and dehumanization of victim. Important Scientific Research and Open Questions Bandura et al. (1996), studied 10–15-year-old adolescents’ proneness to moral disengagement (such as to resort to moral justification, euphemistic labeling, advantageous comparison, displacement and diffusion of responsibility, distortion of consequences, and dehumanization of victim) and found high correlations between moral disengagement and delinquent behavior. In his more refined version of social cognitive learning theory, Bandura (1991) postulates the concept of “moral agency” – a mechanism through which “moral reasoning is translated into actions through self-regulatory mechanisms rooted in moral standards and self-sanctions” (Bandura 1999, p. 2). In the course of moral development, the emergence of moral agency can provide gradual substitution of external sanctions and demands by symbolic and internal moral motivation. In the above study (Bandura et al. 1996), children who were prone to moral disengagement exhibited a higher level of interpersonal aggression and delinquent behavior than individuals who maintained a high level of moral agency. Other theorists, however, argue that social cognitive learning theory alone cannot exhaustively account for learning processes such as moral development. According to these theorists, moral development cannot be reduced to cognitive mechanisms, such as observation and imitation, but has to include emotional processes as well. For instance, Baumrind (1967) found that children who displayed most competent and mature social and moral behavior had loving, demanding, and understanding parents. In contrast, restrictive, punitive, and unaffectionate parents mostly had disphoric and socially immature children. Although the connection between child-rearing practices and children’s psychological development is a complex one and depends on children’s individual differences (Kochanska 1991; Kochanska et al. 1989; Lamb 1982), the view prevails that parental warmth, cooperation, and helping in treating their children; understanding children’s needs; and respecting the child’s self-esteem facilitates children’s moral development (Damon, 1988; Dunn et al. 1995; Higgins, 1989; Maccoby, 1980; Maccoby and Martin, 1983; Walker and Talor, 1991). While it is true that children acquire the positive moral image of themselves through the mechanisms of social cognitive learning, this image can only become attractive if it acquires an emotionally positive value for the children. This positive emotional value can only be achieved if children are treated in a trusting and loving way, if they have a fair share of their parents’ time and personal attention to their needs.

Social Cognitive Theory ▶ Social Learning ▶ Social Learning Theory Social Competence ▶ Socialization-Related Learning Social Construction of Learning CURT DUDLEY-MARLING Lynch School of Education, Boston College, Chestnut Hill, MA, USA S 3095 Definition Researchers who emphasize a social construction of learning present learning as a social and cultural process that occurs in the context of human relationships and activity and not just “in the heads” of individual learners. In this “social” formulation of learning, the ▶ sociocultural context is not merely the location of learning. The sociocultural context affects how people learn (through participation in ▶ cultural activities) and what is learned (▶ social practices), and is itself part of what is learned. Crucially, psychological (learning) processes are not independent of the sociocultural context; indeed, they are constituted by the context of which they are a part (Cole 1996; Gee 2008). Theoretical Background In the fields of psychology and education, cognition has tended to be situated in the heads and bodies of autonomous individuals for whom learning is largely a solitary, mental activity. Dominant metaphors for thinking and learning which conceive of the mind as a storage device or an information-processing machine reflect this “in-the-head” conception of human learning. This highly individualistic conception of learning is, however, being challenged by developments in the fields of cultural and clinical psychology (e.g., activity theory, situated learning, narrative therapy), the learning sciences (e.g., sociocultural studies of mind, constructivism), sociology (e.g., social constructivism), anthropology (e.g., ethnography, ethnomethodology), sociolinguistics (e.g., discourse analysis), and related disciplines (e.g., literary criticism, cultural studies, disability studies). Social constructions of learning differ from primarily psychological, in-the-head conceptions of learning in terms of what is learned; where and how it is learned; and, where knowledge (what has been learned) resides or is stored. It is important to acknowledge, however, that there are a range of perspectives on the social construction of learning that vary according to the degree to which they emphasize the social and psychological dimensions of learning. The perspective presented here reflects the social end of the psychological–social continuum. Synonyms What Is Learned Distributed cognition; Situated learning; Social constructivism; Socialization of intelligence Conventionally, learning is understood to be a matter of acquiring knowledge and skills. Children learn to S 3096 S Social Construction of Learning talk, read, and write, for example, by acquiring a set of skills associated with effective reading, writing, and speaking. However, a social construction of learning holds that people do not learn to read, write, or speak “once and for all.” Instead, they learn to read, write, and speak in particular ways, for particular purposes and audiences, in particular social settings (Gee 2008). Specifically, reading, writing, and speaking are sets of social practices that enable participation in particular cultural activities in various cultural communities. Crucially, these social practices involve more than mastering a set of linguistic skills (vocabulary, syntax, etc.). Language practices, for example, always involve ways of behaving, thinking, interacting, valuing, believing, and speaking, in short, becoming particular kinds of people (Gee 2008). The use of language as part of a religious ritual, for instance, includes saying and doing just the right things in just the right way and the right time in the appropriate setting. Moreover, the right sort of clothing, demeanor, and attitude and beliefs will also be necessary for this social practice to “count” as a religious expression. In other words, participating in this social practice involves being a particular kind of (religious) person. Other social practices, entailing different purposes, settings, participants and so on, involve learning to become different sorts of people. In this sense, learning implies becoming a certain kind of person, indeed, becoming different sorts of people (i.e., different identities) in various social and cultural settings. In other words, what is learned are different relationships among and between people in various contexts; therefore, learning always involves the construction of identities (Lave and Wenger 1991). Ultimately, the community will adjudicate learning, that is, whether people demonstrate they have learned by showing that they have learned to be the “right sort of person” in particular social/cultural settings. A social construction of learning indicates that what people learn is largely about participating in various communities. This is also where meaning resides since people always make sense from a particular (cultural) perspective. But this is not just about learning in (a social) context. The sociocultural context is not just where learning takes place or where knowledge is constructed; it is part of what is learned (Cole 1996). So what is learned is always social and, therefore, all knowledge carries social and cultural meanings. Even what appears to be solitary learning has social character since people learn as members of social and cultural groups and what they learn is related to social practices that are enacted in communities. Bakhtin famously argued that language – perhaps the most powerful of cultural tools – is far from a neutral medium since is it is “overpopulated with the intentions of others” (Bakhtin 1981, p. 294). Language, the learning tool extraordinaire, is saturated with social, cultural and historical meanings; therefore, learning mediated by language – as is usually the case for higher-order learning – will always have a social character. Given that the primary tool for learning, language, is imbued with a social and cultural quality, even what appears to be solitary learning has a social character. Where and How Learning Occurs Conventionally, it is understood that learning occurs in the minds and bodies of autonomous individuals. In contrast, a social construction of learning emphasizes the profoundly social/cultural character of learning. In this formulation, learning is a process that takes place in participation frameworks and not in the minds of individuals. It is in the context of engagement with participation frameworks that people learn to engage in cultural activities (social practices) that make them into particular kinds of people (Lave and Wenger 1991). However, people cannot participate or learn to participate in cultural activities or practices on their own. Effective participation in cultural practices requires coordinated activity among members of the cultural community and it is this coordinated activity that is learned. Moreover, coordinated action is how learning occurs and where it occurs. The metaphor of a dance is a useful, if somewhat oversimplified, way to explicate this coordinated action in which various members of the community work (dance) together to perform social practices that enact particular (learning) identities for each of the participants. Consider, for example, the context of formal school learning. The teaching–learning interaction can be likened to an intricate dance to which both students and teachers contribute. This dance is mediated by the curriculum, school policies, the culture of the school and classroom (and schooling more generally), the language of students and teachers, and so on. Take the classic initiation (teacher asks a question) – response (student answers the question) – evaluation (teacher evaluates Social Construction of Learning the correctness of the student’s response) (IRE) paradigm, for example. In the context of the IRE paradigm learning has a very particular meaning but for students to succeed – or fail – requires the coordination of a particular set of moves by the teacher and the student. It also takes someone with the authority to adjudicate the student’s response, in this case the teacher. Importantly, different moves by the teacher (or the student) will alter the shape of the dance, potentially transforming students’ and teachers’ identities. If, instead of responding to an unexpected response by a student with an evaluation (the “E” in I-R-E), the teachers asks, “what do you mean?” she transforms her relationship with her student and, ultimately the meaning of learning. In either case what students and teachers learn is a socializing routine, a particular set of moves or practices that “count” as learning in the classroom. They also learn an identity. In the case of I-R-E, students are positioned as “getters of the answer the teacher has in mind.” In the alternative example, students are positioned as thinkers or explainers. The meaning of coordinated actions – in this case school learning – also relies on just the right people doing just the right moves in a particular time and place. The I-R-E paradigm, for example, would signal a very different meaning performed outside the context of a classroom (in say, a bar) or if the evaluative move was performed by someone who had not been granted the authority to adjudicate the performance of the other party. The teaching–learning “dance” in a classroom has a particular character that sets it apart from other kinds of learning. But the concept of learning as coordinated action among particular people performing just the right action at the right time and place applies to all forms of learning from learning to drive a car, learning to cook, learning to read, write, or speak, or learning to make love, to learning to solve a math problem. These are all social/cultural practices that are learned through the process of coordinated actions in contexts where these practices are being performed. From the perspective of a social construction of learning, learning is very much context specific, guided by others, and mediated by particular cultural tools and artifacts. Returning to the dance metaphor, learning the dance depends on people working together to accomplish a particular set of moves that will be recognized as dancing. These moves cannot be accomplished by a person acting on S 3097 their own or without the aid of music and, perhaps, props (certain dances require specific clothing, spaces, etc.). Again, learning is never a solitary activity accomplished by autonomous individuals. Things (i.e., neurological activity) do go on in peoples’ heads, but those processes are inextricably linked to social, cultural, and historical factors. Learning is in relations among people in coordinated activity in, with, and emerging from the socially and culturally constructed world (Lave and Wenger 1991). This is what is learned, how it is learned, and where learning occurs. Where Learning Resides Social/cultural practices are what people learn, how they learn, and the location of learning. Therefore, learning resides in the practice; it is distributed across cultural practices in the actions of people as they participate in (cultural) activities, in the cultural tools (like language) that have been created as part of the practices, the social setting, and so on. Returning to the metaphor of the dance, the “memory” of the dance simultaneously inhabits the dancers, the music, the venue created for the performance of the dance, even the dancers’ shoes and clothing. In other words, the memory of the dance is in the dance. Learning to participate in the school practice known as InitiationResponse-Evaluation (see above) resides in teachers, students, curriculum, and testing materials, the physical organization of the classroom (teacher standing in front of students seated in rows), and most of all in the language teachers and students draw on to enact this practice. Ultimately, learning does not belong to individual persons, but to the various cultural activities or practices of which they are a part (McDermott 1993). In this way, learning is distributed across people as they participate in culturally relevant activities (Robbins 2005). Important Scientific Research and Open Questions Experimental and quasi-experimental approaches to research based on assumptions about learning as the possession of autonomous individuals are inadequate for investigating questions animated by a social construction of learning. Ethnographic research methods are better suited to capturing the immediate context of learning but still fall short of accounting for the nearly infinite complexity of social, cultural, and historical factors that comprise the sociocultural context of S 3098 S Social Constructivism learning. So there is a need for the development of innovative research methodologies that capture the complexity of human learning in and through social and cultural practices within particular learning contexts. This project might also include the search for new metaphors for understanding learning. A social construction of learning rejects container or computerprocessing metaphors for human learning but language in cultures that valorize the autonomous individual is generally inadequate for describing sociocultural models of learning.

KITTS2 1 Department of Sociology/ICS, University of Groningen, Groningen, The Netherlands 2 Graduate School of Business, Columbia University, New York, NY, USA Synonyms Clustering; Opinion dynamics; Polarization Definition It is a truism that everyday social interaction leads to interpersonal influence. We often see that influence leads interaction partners to grow more similar in opinions, values, and behaviors. This pattern may be Social Influence and the Emergence of Cultural Norms S because interaction partners exchange arguments and persuade each other directly, or may be due to imitation or social learning among peers, or may also be because interaction partners are exposed to common external influences, such as groups that pressure members to conform to shared norms. Cognitive consistency theories provide one account for this increasing similarity among friends, by assuming that people have a motivational drive to be similar to people that they like or respect. In order to resolve the dissonance caused by disagreeing with friends, actors may try to convince friends to adopt similar opinions or may change their own opinions to conform to their friends. Social influence can lead to complex dynamics in groups where several individuals influence each other repeatedly (Mason et al. 2007; Latane et al. 1994). Researchers have developed ▶ formal models to investigate these dynamics in ▶ social networks, and applied them to theoretical problems like the emergence of shared ▶ cultural norms, the persistence of cultural ▶ diversity, the development of organizational culture, conflicts in work teams, and clustering and ▶ polarization of political opinions. has a very simple influence network – a line. That is, actor 1 is only influenced by actor 2. Actor 2 is only influenced by actors 1 and 3. Actor 3 is only influenced by actors 2 and 4 and so on. At the beginning of the process, actors in the interior of the line do not change their opinions because the influences by their two neighbors balance each other out. However, actors 1 and 10 are each influenced in only one direction by a single neighbor – who has a less extreme opinion – so they develop more moderate opinions. This compromise by actors 1 and 10 causes the opinions of actors 2 and 9 to become less extreme, triggering opinion adjustments of actors 3 and 8, and so on. As Fig. 1 illustrates, the opinions of the actors converge toward a common value (a shared norm) in the long run. In fact, as long as the influence network is strongly connected (i.e., there exists a directed path connecting each pair in the influence network), the classical influence model always generates convergence to global uniformity. In other words, the group will converge toward a uniform opinion unless the network is broken into subsets that have no influence on one another (Mason et al. 2007). Theoretical Background Important Scientific Research and Open Questions When two individuals influence each other, they typically become more similar. In social groups, this influence can lead to self-reinforcing dynamics that drive the group toward homogeneity. To illustrate this, Fig. 1 shows a typical linear influence process in a group of ten individuals, labeled 1–10. At the outset of the influence process, each individual holds a numerical opinion corresponding to its label. Furthermore, the group 10 9 8 Opinion 7 6 5 4 3 2 1 Time Social Influence and the Emergence of Cultural Norms. Fig. 1 Classical social influence model The pervasive drive toward uniformity is puzzling because it seems to contradict the high diversity of opinions and behavior that we observe empirically, even in small groups where the network is strongly connected. In these cases, social separation cannot explain the diversity of opinions, if influence operates as described in the classical model. A common extension of the basic influence model is the assumption of homophily, represented by the adage “birds of a feather flock together.” This principle of social network formation – that individuals develop and maintain social ties to others who are sufficiently similar to themselves – is analogous to ▶ Hebbian Learning in neural networks. In tandem with the classical influence model, homophily implies a positive feedback loop: If relatively similar actors interact and influence each other, they become even more similar, which increases interaction and thus greater similarity. However, a second set of actors that is sufficiently dissimilar from the first set (but similar to each other) may converge toward their own norm, while ignoring or forgetting the first set. In this way, distinct clusters 3099 S S Social Influence and the Emergence of Cultural Norms Opinion Opinion 3100 Time Social Influence and the Emergence of Cultural Norms. Fig. 2 Social influence model with homophily of similar actors can emerge and persist over time (Hegselmann and Krause 2002; Axelrod 1997). To illustrate how the interplay of selection and influence triggers cluster formation, Fig. 2 shows a scenario with 100 individuals having random opinions at the outset. Individuals have social ties to (and are influenced by) others that are relatively similar but ignore others that are very different. In contrast to the classical social influence models (see Fig. 1), distinct clusters form in these conditions. Dynamics settle when the clusters are internally homogeneous. Thus, the interplay of homophily and social influence offers an explanation for the emergence and persistence of subgroups with distinct opinions or behaviors. However, this theory fails to explain polarization, the development of increasingly different subgroups. Trying to explain polarization, researchers have gone beyond the homophily assumption and assumed that actors actually differentiate themselves from others who are very different (Macy et al. 2003). Figure 3 illustrates the implications of such negative influence tendencies. In this model, individuals are positively influenced by similar others (“friends”) as before, but form negative ties to very dissimilar others (“enemies”), which convey negative influence. At the outset, opinions are uniformly distributed. Individuals with moderate opinions do not change their opinions much at the beginning of the influence process because they receive balancing forces of influence in both directions. However, individuals who hold relatively extreme opinions are driven to differentiate themselves from enemies at the opposite extreme. As more individuals adopt very Time Social Influence and the Emergence of Cultural Norms. Fig. 3 Social influence model with differentiation extreme opinions, the influence of the extremists on the moderate individuals increases in strength. As a consequence, moderate individuals gradually turn more extreme. Opinion dynamics settle when all individuals hold an opinion on one of the two poles of the scale. Of course, uniformity remains an equilibrium under this model, but this tendency to differentiate from enemies creates a powerful force toward polarization that in most conditions will prevent convergence toward uniformity in heterogeneous groups. Formal models of social influence in networks are highly abstract, as they are based on strong simplifying assumptions about individual behavior. Some researchers are validating these models by bringing them into dialog with empirical data. For example, social psychologists have studied social influence through networks implemented in experimental laboratories, and have also explored the conditions under which pressures to uniformity will be realized in small groups. Field researchers study influence networks through e-mail communication or contacts on social networking Web sites.

Social interaction learning styles are models that learners strategize in their acquisition of knowledge and information. Learning is the process by which behavior is modified according to the experience and exposure presented to learners in different settings. This process involves interaction between the teacher and the learner in different settings, which allows for information dissemination and, in turn, how the information is received by the learner. Such an activity is termed as social interaction which comes with scales of varying relationship promoted among individuals that are in the interaction. Simultaneously, learning styles include the personal quality that influences a learner’s ability to acquire knowledge. As early as the nineteenth century, the concept of social interaction stems from social behavior which has two components, stipulated by which are the actions and the orientation the actions are being attached to by the actor(s). Later toward the last century, the social interaction scientist, Kurt Lewin proposed the concept of group dynamics. This interaction sees the relationship between individuals as well as between individuals and the group. Learning styles are the learning preference a learner adopts in ensuring the acquisition of knowledge and information in a learning setting. They can also be personal quality that influences a learner’s ability to acquire information. This is conducted in the way a learner interacts with his peers and his teachers and the way he participates in a learning experience. Experts have presented the learning styles in the way a learner approach a learning environment. Teachers need to understand the importance of learning styles as these provide guidance for improved teaching and learning process. Further understanding of the learning styles enables teacher to strategize teaching approach to suit the differing manner of learning among the learners, hence, reducing frustration in teaching. When such an understanding is established, it will then propose the utilization of social interaction learning styles which provide educational institutions with a better approach to handle differing learner’s learning preferences and therefore, assist in the development of curriculum.

It revolves around three dimensions, namely, learner’s attitudes toward learning, learner’s views of teachers and their peers, and learner’s reactions toward classroom procedures. While this exploration is partaken by the learners, the patterns of preferred styles for interaction with teachers and peers are further classified as social interaction scales identified as Avoidant-Participant, Competitive-Collaborative, and Dependent-Independent. However, for the discussion, the following presents the learner’s preference in learning, each of this includes (Riechmann and Grasha 1974): ● Avoidant: Usually classified as low achiever, this ● ● ● ● ● learner may have a different focus in his learning as he takes less responsibility in his learning. Participative: This is the type that enjoys pleasing the teacher. He is interested in class activity and is keen to complete his lesson within the time frame of learning. Competitive: The learner tends to be wary of his peers and that he will be in a mode to do better than the others. Collaborative: This learner enjoys group discussion in which he is able to gather information through sharing and cooperating with his teachers and team members. Independent: The learner prefers independence and self-paced activity as he enjoys working alone. Dependent: As the term suggests, this type of learner prefers having the presence of expert as a source for guidance in deciding what to do. Curry’s Onion Model (1983) This social interaction model is one of the learning styles models which suggest for consideration to vary the strategies adopted by the learner to suit his specific environment and social context (Curry 1983). Kolb’s inventory includes four dimensions namely diverging, assimilating, converging and accommodating. Learner who has diverging learning style prefers to feel and look at things. This type of learner prefers gathering information and uses imagination to solve problems. In doing so, they work well in groups, and the divergent learner enjoys brainstorming learning approach. The next in the inventory list is the assimilating learning preference sees the learner who enjoys ideas and concepts rather than people. The learner is more percept to ideas than practical application. Hence, he learns well in lecture, exploring analytical model and in reading in which there is time for him to think. The next type of learner prefers using his learning to look for solution. In his way of learning, a learner practices what he learns to work out ways to solve problems and to make decision, and this is known as the converging learning style. Finally, in Kolb’s inventory, the next type of learner prefer doing and feeling in his learning or known also as accommodating. This learner prefers experiential and practical ways to solve problems. He is a team player and sees learning well using other learner’s analysis and ideas (Kolb 1984). Gardner’s Multiple Intelligences (1985) Perhaps the most identifiable of learning preference is that proposed by Howard Gardner. His concept of multiple intelligences identifies learner as the following (Gardner 1985): ● Visual: The learner has to have the presence of his teacher as he takes to learning from the teacher’s facial expression and body language. He learns best visually, thus taking down notes and prefers to be in front of the class. ● Auditor : As the term suggests, this learner listens well and is attentive in lecture and discussion. Although taking down notes is not a preference, learning is best when there is reading aloud or recording his voice. ● Kinesthetic: The learner prefers learning actively and physically. Having short attention span, he has to be given the liberty to “move around” and to be provided with hands-on activities. Kolb’s Learning Styles Inventory (1984) Gregorc’s Mind Styles Model (1985) Kolb Learning Styles Inventory is probably the most distinguishable among the rest of the proponents. As in Kolb’s, Gregorc’s Mind Styles Model identifies four types of learning preference. The first is known as Social Interaction Learning Styles Concrete Sequential which identifies learner who prefers instruction, following logical sequence and getting facts. A practical person, this learner works well in a structure environment and does not enjoy abstract ideas nor working with ambiguity. In Gregorc’s inventory, a learner who enjoys personalized environment, given instruction and does not like competition, is known as Abstract Random. This learner prefers working in a friendly situation in which strict teacher and negative criticism are not welcomed. The next is Abstract Sequential which describes a learner as one who prefers stimulating environment that allows for appreciative listening and presence of reference to work out solutions. This type of learner does not learn well in a pressured environment of repetitive activity and undiplomatic team members. The last type of learning preference in this Model is known as Concrete Random sees a learner who enjoys to experiment, to find answers, and to solve problems independently. He has competitive spirit in his learning and does not learn well with restrictions and repetitive activity. S 3103 ● Analytic: This learner draws from his learning the important things that can add to his world of knowledge. In his reflective mode, he wants to develop intellectually. ● Common sense: When a learner goes for answers in an active and straightforward approach, he also looks for practical and useful ways that can make things happen. ● Dynamic: This is the kind of learner that tends to use his “gut feelings” to look for possibilities in his quest for learning. He is daring, loves adventure and spontaneous. Important Scientific Research and Open Questions Wratcher et al. (1997) That learner takes learning differently is widely accepted and teacher has to be aware of the varieties he has in his lesson in order to strategize for effective teaching. This awareness helps a teacher to better understand the different needs of his learners. Myers–Briggs Type Indicator (1985) In Myers–Briggs Indicator, there are eight classifications that identify a learner’s style. The list includes Introversion in which a learner’s interest is in the inner world of concepts and ideas. The next is Extroversion in which preference in learning goes for actions, objects, and team work. A learner who prefers immediate and practical information is in the classification of Sensing. Next, in the preference for Intuition, a learner tends to perceive meaning of experiences and possibilities to establish his purpose. When one prefers to make decisions rationally, the classification is known as Thinking, while the one known as Feeling, this type of learner will make decision based on his subjective emotion. Judging sees the learner to tend to take action in a planned and definite approach and finally Perceiving identifies the learner as one who prefers to take action in a flexible but flighty manner. McCarthy’s Learning Styles (1990) There are four learning styles as identifies in McCarthy’s and the following are (McCarthy 1990): ● Innovative: This type of learner tends to enjoy the values he learns from his lesson via social interaction and enjoys cooperation. Diaz et al. (1999) The study focuses on the discovery of relationships between learning styles and specific learner’s achievement outcomes. These outcomes encompass dropout rate, completion rate, attitudes about learning and predictors of high risks.

Interacting with other people has proven to be quite effective in assisting the learner to organize their thoughts, reflect on their understanding, and find gaps in their reasoning. Underneath the broad umbrella of social interactions and learning, variants can range from peer learning, reciprocal teaching, learning by teaching, learning by observation, learning by doing, and self–other monitoring. These areas overlap in scholarship and are often an optimal way to help students learn. Different forms of collaborative learning can create ideal circumstances when examining the impact of social interactions on learning. Theoretical Background Vygotsky believed that culture, history, and social interactions play a critical role in the cognitive development of children. Through observation, Vygotsky found that children develop higher mental functions such as identifying speech patterns, learning a language, and deriving meaning from symbols, when interacting with parents and other adults within the community. Vygotsky referred to language, numbers, signs, and symbols as cultural tools that help integrate the child into the culture. Vygotsky believed that the internalization of these cultural tools led to higher thinking skills. Children first learn how to use these cultural tools through the social interactions with parents, teachers, or more experienced peers, and later internalize the skills so they can perform independently. This is different from Jean Piaget’s understanding of child development where development precedes learning. Vygotsky’s Zone of Proximal Development (ZPD) is a theory about the dynamic relationship between learning and development. ZPD is the area between the learner’s independent performance level and the level that can be achieved with assistance of a more knowledgeable peer. ZPD not only reveals the learner’s potential but also shows that with assistance, a higher performance level can be achieved. Social interaction is also a critical component for other theories. Vygotsky’s theories were further elaborated upon by other researchers and implemented into practical applications. Some examples are Situated Learning, when learning occurs in the same context in which it is applied. Learning is a social process that is co-constructed through the involvement in “community of practice” where members of the community share information and learn from one another (Lave and Wenger 1990). The novice learner embodies beliefs and behaviors through social interactions with more experienced members of the community. With time, the learner moves from the periphery of the community to the center, becoming more engaged and active within the culture, and eventually takes the role of the expert or senior member. Another example, Cognitive Apprenticeship (Collins et al. 1989), further develops the theory of knowledge construction through social interactions like coaching, scaffolding, modeling, and Social Interactions and Learning reflection. Reciprocal teaching (Palincsar and Brown 1984) is when the teacher or peer provides the learner with guided practice using four strategies of summarizing, question generating, clarifying, and predicting, when reading a piece of common text. The learner and teacher (or peer) take turns playing the lead role as a teacher, and use the four strategies to support their discussion on segments of the text. Over time, children begin to internalize the processes until the strategies become a natural part of their internal reading and listening skills. The strategies help the learner and teacher (or peer) develop deeper understanding of the text and better reading comprehension skills. These theories have also been applied in the context of technology-based learning activities. Peer learning and collaborative learning was once only possible in shared physical space, but now learners can participate remotely via the Internet and technology-mediated tools. Important Scientific Research and Open Questions People learn from various sources. Traditional sources involve learning from humans or objects (e.g., books), while recent sources may involve computerized people (e.g., pedagogical agents and avatars) and/or computerized instructions (e.g., intelligent tutoring systems). Social interactions also occur in various settings. Traditional settings involve face-to-face interactions in both formal and informal environments (e.g., classroom and private tutor), while recent settings can involve online learning environments (e.g., video conferencing systems like Adobe Connect and virtual reality environments like Second Life). Under this broad umbrella, the following may be considered: (1) learning in social interactions with others, (2) learning in social interactions with others through ▶ computermediated communication (CMC), and (3) learning in social interactions with technology. Learning in social interactions with others: People often turn to others for learning. Social interaction plays an important role in learning, and has proven to be quite effective in peer learning, reciprocal teaching, and behavior modeling. Such forms of collaborative learning are often an optimal way to help people learn (Chi et al. 2001). For example, Learning by teaching and explaining to others can be an effective way to learn (Palincsar and Brown 1984). Another situation may be S learning by observing other people. In tutoring, one observes whether their pupil applies what they were taught during problem solving. Their pupils’ performance can reveal gaps in what the tutor taught and perhaps understands. The performance of the pupil can provide alternatives the tutor did not think of. Even if these alternatives are not correct, they may slow down the tutor’s natural inertia to keep thinking in the same way. Studies have shown that learning among peers can be very useful in several ways. Learning can occur by comparing ourselves to peers, or observing others to develop a better understanding of the self. For example, even if a student cannot solve a math problem, observing someone else may help you learn how to solve the problem. This is because the person they are observing can provide a model of competent performance. In other situations, interacting with somebody who knows about the same as (or knows less than you) can be beneficial. For example, in reciprocal teaching, students may spontaneously compare their understanding to what they observe in another person, and any discrepancies can alert them to think more deeply about who is right. This implies that observing a peer, under the right circumstances, can trigger learning and reflection. In other cases, just anticipating a social interaction can lead to more learning. For example, preparing to teach others influences students to learn more compared to students who study for themselves (e.g., study for exam). In this case, learning occurs just with the “thought” of a social interaction. Learning in social interactions with others through computer-mediated communication tools: There is no need to be physically present to learn in person. Through the use of the Internet technology and computer-mediated communication tools, real-time social interactions are possible. Many synchronous online learning (or distance learning) environments use video conferencing tools that allow face-to-face interaction via technology mediation (e.g., Adobe Connect). More recent forms of online learning may involve virtual reality (e.g., Second Life) where your peers are represented by a computer graphic character that they remotely control in a virtual reality environment (e.g., an avatar). Such technological tools allow real-time exchange of audio, video, text, and graphical information between learners (Dede et al. 2002). Successful virtual reality environments such as Second Life and Active Worlds provide space to support online 3105 S 3106 S Social Interactions and Learning group activities. There are some concerns that social interactions are limited in online learning, compared to the traditional face-to-face learning experience. Others attest that technology-mediated tools can elicit social responses and create unique social interactions with interesting implications for learning. For example, children can build their own simulated world (e.g., Ecosystem) rather than passively partake in a given situation. This may allow children to directly experience the causal chains from their actions and help visualize and reason about the situation. Another distinct feature in virtual reality is that the learner’s environment can be manipulated based on their needs. For example, the teacher can be represented differently to communicate with the learner in the most optimal way (e.g., with or without eye contact), allow the learner to experience different points of view (e.g., first person, third person, and birds-eye view), and the seating in virtual classrooms can even be positioned based on the learner’s attention level. Learning in social interaction with technological tools: Applying educational content and pedagogy to technology is not new. The first testing and teaching machine by Pressey appeared in 1926, and since then people have had high hopes for technology in restoring personalized instruction. Technology has the potential to provide a wide range of tools tailored to each student’s learning needs. However, much of the learning in the initial stage focused on machine learning, intelligent expert systems, and computer modeling of human behavior. Expert systems were successful in their intended domain, but often evaluated unfairly, because of the high expectation of the Turing Test. Some have argued that by making machines smarter, good teaching and tutoring strategies can be implemented for the learner. However, interactions with intelligent machines do not always guarantee learning. Learning can be difficult without a meaningful interaction between the human and machine. Recently, development has shifted the focus from intelligent to directable technologies in assisting human learning. Computerized people and instructions still consist of intelligent behaviors, but more emphasis is placed on human-like features for eliciting social responses. Technological tools such as pedagogical agents, tutoring agents, and humanoid robots, consist of strong social components that enable students to share knowledge and build peer-like relations. However, not all technologies put emphasis on direct social exchange with humans (e.g., industrial robots). Most fall somewhere in between, and partake of both machine-like and human-like features (e.g., pedagogical agents and humanoid robots). Some systems may tacitly draw on social schemas, but not include a real social presence or metaphor. For example an intelligent tutor that is a computational model may represent student thinking and cognition, but its appearance may be a disembodied text with no visual character. Other systems build on explicit social metaphors of interaction and appearances to invite social interaction. An example may be a socially explicit pedagogical agent taking on the role of a peer learner. Students learn by teaching this pedagogical agent. Based on what the agent is taught, the agent can answer questions. Students can observe their agent’s answers and revise the agent’s understanding (and their own). The learner can structure their thoughts through the social interactions with the agent, and even develop metacognitive skills (Biswas et al. 2001). Aside from content, advancement in sensors and audio-visual tools has helped detect human behavior (e.g., physiological sensors). Automation and expressive tools have helped technological tools respond to humans. Sensors and behavior models implemented into the system have improved some aspects in the quality of social interactions between human and machines. However, technological tools still fall short when coming across unfamiliar content, and do not easily afford the wide range of possible social interactions. Unlike a human peer or teacher, technology presents limitations, where the learner may often times be constrained by what the tool (e.g., pedagogical agent) or environment (e.g., Second Life, avatars) can do in response. Until technological tools have both the intelligence and flexibility to respond to the learner’s interactive bids, examining the social exchange and interactive styles that guide learning is crucial.

Social Interest Behaviors ▶ Altruism and Health Social Learning EYLEM SIMSEK Department of Communication, Anadolu University, Eskisehir, Turkey Synonyms Imitation; Modeling; Observational learning; Social cognitive theory; Vicarious learning Definition Social learning is the synthesis of cognitive psychology and behaviorism, emphasizing the role of personal S 3107 cognitive capability and the environment. On the one hand, neither classical nor operant conditioning of behaviorism explains the unreinforced behaviors. On the other hand, cognitive theories mostly ignore the role of environment. As a theory of interwoven, social learning assumes that one can learn by observing the behaviors of the other under certain environmental conditions; this process is often called vicarious learning. According to the behavioral psychology, the imitated behaviors are those reinforced. This approach implies operant conditioning of behaviorism. Skinner focused on the extrinsic reinforcement for learning. In contrast, Bandura (2001a) underlines in his social cognitive theory psychological mechanisms of the self system and socio-structural factors which together constitute behaviors. Learning is not as simple as stimuli, extrinsic reinforcement, conditioned stimulus, and imitation; one can learn by observing and modeling so that social learning depends largely on reasoning the consequences of the actions. Theoretical Background The term of social learning is often attributed to Albert Bandura, who is one of the important pioneers in the field of social learning. However John W. Watson, Neal. E. Miller, John Dollard, and B. F. Skinner are former contributors in this area. The first social learning theorist is John B. Watson (1878–1958), who is also the founder of behaviorism. In opposition to the previous “tabula rasa” view, he argues that the behaviors are learned and this development process is continuous without clear-cut stages. He discusses that behaviors usually precede the learning of rules and laws, except some human reflexes. Under this conception, three main social learning approaches have been developed: neo-Hullian Approach, Skinner’s operant-learning model, and Bandura’s cognitive social learning model (Shaffer 1988). Neo-Hullian Theory explains social learning with habits. This theory departed from the Freudian view claiming that human behavior depends not only on instincts but also on the primary and secondary drives. Primary drives are inherent, whereas secondary drives are learned by experience. Behaviors could be changed by stimulus and response interaction. However, reinforcers are those responses who reduce drives. Primary reinforcers, often acquired inherently, are basic needs S 3108 S Social Learning for survival such as water and food. On the other hand, secondary reinforcers are associated with higher needs such as love, status, etc. After the association of the neutral stimulus and consequence of behavior, secondary reinforcers are formed. From the social learning perspective, Miller and Dollard focused on reinforcement for acquiringstable social behavioral patterns, called habits which are accepted as a part of personality. They claimed that secondary reinforcers are more influent on the development of habits during the daily life (Shaffer 1988). Operant-learning theory contributes to social learning by underlining the importance of environment on behaviors. Skinner, one of the most prominent behavioral psychologists, was interested in learning within the scheme of operant conditioning and volunteered behavior instead of reflexes. Of course, reinforcement plays a crucial role in this process. Reinforcer is defined as an external or internal stimulus that strengthens the behavior. Secondary reinforcers are used much more in this context than primary ones, similar to neo-Hullian perspective. Operant conditioning gives more attention to external stimuli in order to increase the frequency or probability of a response. Positive and negative reinforcers along with punishment are instruments to shape and/or change certain behaviors. Antecedent and consequent events act as reinforcer and shape the behavior. Shaping is the key factor explaining social learning patterns in terms of behaviorism (Glover and Bruning 1988). Finally, cognitive social learning theory combines the neo-Hullian and the behaviorist approach, adding cognitive perspective to the equation. Outcome expectations as acting reinforcers mostly cause the behavior in social learning. Operant conditioning depends on behaviors that are performed. This is the main difference between cognitive social learning approach and the previous approaches. In many cases of social learning, one could learn by observing without any stimulus, reinforcement, response, or drives. Cognitive social learning theory was adopted from social cognitive theory. Bandura (2001b) indicates that human behavior is explained generally by unidirectional view such as by environmental influences or by internal dispositions. Social cognitive theory, however, follows triadic reciprocal causation for human functioning. In this transactional point of view, personal, behavioral, and environmental determinants operate bidirectionally (Fig. 1). Reciprocal determinism is one of the key terms of social learning. In contrast to environmental determinism, behavior is the result of interaction results between prior learning and present environmental conditions. According to social cognitive approach, society and personal interactions have influences on behavior as well as social learning. Bandura assigns people as an active role rather than passive recipients throughout self-reinforcement mechanisms of learning. People are self-organizing, proactive, self-reflecting, and selfregulating organisms rather than being shaped only by intrinsic and extrinsic forces. Symbolizing capability, self-regulatory capability, self-reflective capability, and vicarious capability of people together enable social learning and modeling via complex cognitive mechanisms. Bandura’s modeling process is operated by four subprocesses. attention, retention, reproduction, and motivation (reinforcement). As well known, one could not be able to learn without paying attention. Attention process is related to the interest, values, attitudes, or personality. People pay more attention to the models who are similar to themselves. People having high status, competence, and expertise are more likely to be imitated. Moreover, incentives and distinctive cues increase attention. Retention is required for future reproduction of the behavior; symbolic coding- (imaginative or verbal) is needed for memorizing the models behavior. Motoric representation refers to self-corrective adjustments of the modeled behavior. Finally reinforcement process enlightens why all observed and learned behaviors are not modeled (Gage and Berliner 1987). Opposite to behaviorism, performance and learning are different phenomena in social learning. People Personal determinants Behavioral determinants Environmental determinants Social Learning. Fig. 1 Schematization of triadic reciprocal causation in the causal model of social cognitive theory (Bandura 2001b) Social Learning in Animals do not perform everything they have learned. The distinction between observational learning and performance-modeling could be clarified by anticipatory mechanisms, which generate positive expectations or incentives. Learning does not guarantee successful behavior or performance. Expected consequences as well as actual ones determine the responses to the observation or modeling (Glover and Bruning 1988). Important Scientific Research and Open Questions Social learning theory is applied to understand aggression with well known “Bobo doll experiment.” Bandura has conducted the series of experiments between 1961 and 1965. The main research question was whether behaviors like aggression are learned by observing or imitating in light of the social learning theory. The children were exposed to aggressive and non-aggressive behaviors to a bobo doll by adult models. Physical and verbal aggression, the frequency of aggression besides hitting the Bobo doll, and non-imitative forms of aggression have been evaluated. As expected, children exposed to aggressive models showed more aggressive behavior than children exposed to non-aggressive models. This experiment proves observational or social learning theory even without any reinforcement on both models and children (Bandura et al. 1961). Bandura’s other experiment in 1963 was designed to show aggressive behavior via video playback. Compared to the real model, video playback is less effective for modeling. The shortcoming of the experiment was that children could hit the Bobo doll only for fun. To sum up, the Bobo doll experiments proved that without any reinforcement one can learn by observing and modeling. The results have implementation for the treatment of phobias, explain the routes of criminal behaviors and measurement of negative television effects (Bandura 2001a, b). There are some criticisms to the social learning approach. First, social learning is criticized for oversimplifying genetic characteristics of people which directly determine the learning capacity. Second, social learning approach is thought as a nondevelopmental theory. Development theories explain specific age-related changes, whereas social learning is a process approach. In other words, the social learning theory could not identify the age and stage development (Shaffer 1988).

Social Learning and Communication ▶ Song Learning and Sleep Social Learning in Animals LUDWIG HUBER Department of Cognitive Biology, University of Vienna, Vienna, Austria Synonyms Observational learning; Socially biased learning S 3110 S Social Learning in Animals Definition Many species live in social groups, which offers the possibility to learn from the behavior of others. Examples of social influences on the adaptive modification of behavior are widespread and diverse, ranging from food selection and predator avoidance to learning of songs, routes, and motor skills. It can also lead to synchrony in the performance of established behavior and the transmission of new behavior patterns throughout a group. These affects are mostly (though not necessarily and not always) beneficial to the observer, either immediately or long term, and are therefore assumed to outweigh potential costs in terms of vigilance, attention, memory, or special learning mechanisms. The term social learning usually refers to learning that is influenced by observation of, or interaction with, another animal or its products. Many people use “individual learning” as a complementary term, to refer to learning that does not involve social interaction or any information that is provided by others. It would, however, be less confusing to use the term “asocial learning,” because in all cases it is ultimately individuals who learn. Social learning may be direct or indirect. Direct social learning refers to learning by observing others, whereas indirect social learning describes processes in which social partners aid the cognitive development of younger animals through the alteration of the physical environment. When formal research on the subject began a century ago, the focus was to identify evidence of social learning in the animal kingdom. It focused on the demonstration of this capacity in a given species and the role of social learning in the ontogeny of adaptive behavior. Much later, psychologists, fueled by the investigation of imitation in human children, became interested in the underlying mechanisms, investigating whether different mechanisms are responsible for social and asocial learning, and whether nonhuman animals are capable of the most cognitively advanced forms of social learning shown by humans. In many cases there is no need to invoke a unique learning mechanism to explain the acquisition process. Indeed, there is great heterogeneity in mechanisms, causation, and possible functions of social learning. Theoretical Background What is the impact of social learning on the development of adaptive behavioral repertoires of naturally living animals? It has been suggested that social learning may fill an important niche between species-typical, genetically predisposed behavior and individual learning. Learning by observing others may provide more flexibility than is possible with species-typical behavior, but it may also shortcut the many iterations of trial and error necessary for most individual learning, and move directly to solutions previously found by others. Broadly speaking, learning can be viewed as an adaptive modification of those neuronal circuits that give rise to behavior. It occurs during the whole lifetime of an individual, but is particularly important during early development. It allows youngsters to fine-tune their behavior to the rapidly changing properties of their local circumstances. Natural selection, acting on genetic variation in a population, is too slow to furnish individual organisms with those adaptations. Social learning can have effects on the small and the large scale. On the one hand, it can aid the development and fine-tuning of important behaviors in the individual. Here the information transmitted between demonstrator and observer is usually of only transient value. On the other hand, social learning can contribute to group- or population-specific behavior. This kind of information transmission would lead to behavioral homogeneity in the group that extends beyond the period of interaction. Generated in this way and maintained over several generations these processes can ultimately result in the emergence of traditions and cultures. A further important question concerns the direction of transmitted information. On the one hand, information can spread through animal populations horizontally, sometimes even between unrelated individuals, as in bird flocks or fish schools. On the other hand, it can be transmitted vertically, from generation to generation, mostly from parents to offspring. Most social learning seems to fall in the highly horizontal category. The transmission of food preferences in rats is one of the best-studied examples of this; the forming of song dialects in song birds or cetaceans is evidence of the vertical category. Mathematical models have been developed to study the costs and benefits of social learning, the effects of social dynamics, the factors that influence the spread of information in populations, the adaptive advantages of social information, and the evolutionary Social Learning in Animals consequences of a capacity for social learning. Furthermore, the debate of animal culture has contributed to the development of “dual-inheritance” models to investigate the complex interaction between culturally and genetically transmitted information. Important Scientific Research and Open Questions Learning about novel food sources is a critical task for most animals. To avoid potential poisoning most species are neophobic toward unknown food items, either avoiding them completely or eating only small quantities initially. During infancy, when virtually all food items are novel, it would be safer to exploit the experience of other conspecifics and to learn about the palatability of unknown items socially instead of through trial and error. Social mediation of food preferences has been found in birds (e.g., pigeons and blackbirds) and mammals (e.g., mice, dogs, and bats). The best-studied example is the Norway rat. It not only learns from elder conspecifics which foods to eat, but is reluctant to ingest foods which older members of its colony have not introduced it to. This social influence can last for a month and can be so strong that it can even reverse conditioned food aversions. Social learning about food is often actively promoted. Food sharing is not only a means of providing infants with additional nutrition or with items that infants cannot obtain by themselves, but also facilitates the transmission of food preferences from adults to young animals. In common marmosets, for instance, food transfers preferably include food that is novel to the infants, thereby fostering learning about it. The most advanced form is tutoring, where the adults track what is novel to the infants. However, evidence for this active demonstrator role is poor in nonhuman animals. Extractive foraging may be the most challenging situation to foster social learning. However, the extent to which social learning helps acquisition of the motor patterns that an animal needs to process encapsulated, or otherwise secured, food remains a contentious issue. Roof rats of the pine forests of Israel only learn to efficiently strip scales from a pinecone (to reveal the pine seeds) if it is demonstrated by skilled conspecifics. Social learning may also be involved in the development of novel feeding techniques in birds, as, for example, in the spread of puncturing the top of milk bottles by great tits. S Concerning the most advanced foraging technique, tool use, the evidence for a major role of social learning is even more ambiguous. Among tool-using birds, two species have been intensively investigated, and the evidence is far from conclusive. In Galápagos woodpecker finches, the use of modified twigs or cactus spines to pry arthropods out of tree holes seems to depend on very specific learning that involves trial-and-error during a sensitive phase in ontogeny. Social learning is not essential for development of this behavior. In Caledonian crows, like in chimpanzees, the use and manufacture of probing tools may depend on prey distribution as well as on genetic differences between populations, though social transmission cannot be ruled out. From a comparative point of view, the question of social learning of tool use in animals is further complicated by the fact that several species of ants use, and even manufacture, foraging tools. Although the social learning of foraging skills is perhaps the most obvious or at least most studied function of social learning, researchers have found social learning effects in many other domains. These include learning how to get to a resource (e.g., in wrasses, grunts, and guppies), how to hunt (e.g., in archer fish, hyenas, killer whales, and chimpanzees), what to fear (e.g., in rhesus monkeys, blackbirds, and minnows), about mate-choice (in guppies and quails), how to court (e.g., in cowbirds), learning of nonfunctional behavior (such a stone clapping in Japanese macaques or fire making in orangutans), greeting gestures (gray parrot), and finally song learning in songbirds and cetaceans. These examples show social learning can occur via many different modalities, including the use of auditory and olfactory cues. Learning from others is not always adaptive. Animals may ignore social information under specific circumstances or switch conditionally between reliance on social and asocial information according to its reliability. Observers are selective in many respects. They do not blindly copy what they see, but take into account the what (goals, actions, results), when (when uncertain etc.) and from whom (the majority, or the age, sex, dominance status, affiliation, and knowledge of the model) to learn. This selective nature of social learning is confirmed by theoretical and ecological models of the adaptive advantages of social learning. Social learning that results in long-term effects on the behavioral repertoire or the knowledge of the 3111 S 3112 S Social Learning in Animals individual should be distinguished from (transient) social influences on underlying motivational and perceptual processes of the observer. The former influences are generally called social facilitation, the increased probability of performing a class of behaviors (e.g., feeding) in the (mere) presence of a conspecific (usually mediated by an increase in arousal or fear reduction). A similar phenomenon is contagion, referring to the unconditioned release of an instinctive behavior or a specific response (response facilitation) in one animal by the performance of the same behavior in another animal. Possible cases of contagion include synchronized predator evasion in flocks and herds of animals, synchronized movements, chorusing by birds, synchronous courtship behavior, contagious laughing, and contagious yawning. However, behavioral synchrony is itself not indicative of any influence through observation of a conspecific. The classical phenomena related to social influences on perceptual processes are local and stimulus enhancement. They refer to the animal’s shift of attention to a particular location or a particular object as a consequence of observing a conspecific engaged in rewarding activity at this location/with that object. This observation may result in an increase in the observer’s interaction with that stimulus and subsequent learning about the distinctive value of that location or object. Here we have some overlap between social influences on learning and social learning itself. While the (short-term) change of (directed) attention would not itself imply learning, stimulus enhancement could be regarded as a subset of single-stimulus learning, where exposure to a stimulus results in a change in the subject’s responsiveness to that stimulus. A clear-cut social learning phenomenon is observational conditioning. Since the observer does not actually experience the unconditioned stimulus, but only observes it, a form of higher order conditioning is involved. Examples of observational conditioning are the learned snake fear in Rhesus macaques and social transmission of mobbing in blackbirds. In the cases of social learning described so far, the response or action of the observers is relatively similar to that shown by the demonstrator. But animals may learn by about affordances, functional properties or operating mechanisms of objects by observing others and subsequently use their own, preferred manipulative movements to achieve similar effects as seen. This is called emulation and is regarded as intelligent problem-solving behavior because it signifies the observer’s ability to understand a change of state in the world produced by manipulations of another. Finally, imitation is social learning about (some aspects of) the behavior of others, rather than its consequences. It is considered an important and intriguing neuro-cognitive process in humans, which promotes empathy and cooperation. Further, it provides a channel of evolutionary, cultural inheritance that makes us distinctively human. However, there is now ample evidence that animals can learn imitatively, though possibly not with the same complexity as humans. Future Research As social learning is considered a major component (prerequisite) of cultural processes, it has become a multidisciplinary research focus. From a biological point of view, a complete understanding requires the integration of answers to four different questions (Tinbergen’s four whys); in addition to the adaptive function (ultimately survival value) and the physiological (neuronal) mechanisms (proximate causation) described here, one needs to consider how an ability arises during an individual’s development (ontogeny) and, finally, how a particular behavior evolved, how it came into existence and changed during the history of the species (phyolgeny). An answer to the latter has been complicated by the fact that solitary species, octopuses and tortoises, can learn by the observation of others. This challenges all current theories about the evolution of social learning that are based on the assumption that social learning is an adaptive specialization for social living.

Social Learning of Fear ANDREAS OLSSON Division of Psychology, Department of Clinical Neuroscience, Karolinska Institutet, Stockholm, Sweden S observing, and listening to others. Because of its reliance on socially transmitted information, SLoF is an indirect (or vicarious) learning procedure in contrast to direct learning procedures, such as classical (Pavlovian) fear conditioning, in which the animal learns to fear a conditioned stimulus (CS) or context through direct, individual experiences of its pairing with an aversive unconditioned stimulus (US). In comparison to direct learning procedures, SLoF provides a less risky and faster way to acquire adaptive avoidance behavior of potentially dangerous events in the surrounding. SLoF is commonly measured through the learner’s expressed fear of a CS in the absence of the individual(s) who transmitted the fear. This feature differentiates social fear learning from related social behaviors, among them imitation and socially facilitated and contagious fear responses, such as those seen in flocks behaving in unison, schools, and herds of animals. Socially acquired fear – like conditioned fear – can be expressed as changes in neural, endocrine, and behavioral systems. Social learning of fear can be further differentiated by reference to the specific means of fear transmission. Two kinds of SLoF have been particularly investigated: (a) observational (sometimes referred to as “vicarious fear conditioning”) and (b) instructed (verbal) fear learning: (a) In an observational fear learning procedure, the learner (observer) attains fear-relevant information by observing a learning model’s (demonstrator’s) expressions of fear, pain, or other distress. This form of SLoF is the most widely studied and has been documented across several social species, such as birds, rodents, and primates. (b) In an instructional fear learning procedure, which due to its reliance of symbolic language is uniquely human, the learner receives fear-relevant information through verbal instructions. In humans, observational and instructed fear learning often co-occur. Theoretical Background Synonyms Social emotional learning; Vicarious fear conditioning Definition Social learning of fear (SLoF) refers to the acquisition of fear through social means, such as interacting, 3113 The powerful effect of socially mediated fear has been discussed by philosophers and capitalized on by the arts since the origin of the Greek tragedies. In modern time, British Enlightenment philosophers, notably David Hume (1711–1776) and Adam Smith (1723– 1790), argued that vicarious emotions (“passions”) S 3114 S Social Learning of Fear were critical to the individual’s social functioning and to moral development and thus to a well-functioning society. Hume’s prophetic speculations about the underlying mechanisms of vicarious fear and anxiety included both accounts of emotional “mirroring” and of “associations” between the present situation and earlier encounters of similar events. The background of empirical research in SFoL can be traced to three different, but partially overlapping, strains of research: (1) experimental research in nonhuman animals, (2) clinical observations in humans, and (3) experimental research on normal healthy human children and adults. 1. Since the first half of the 1900s, fear learning through social observation has been identified in both humans and several other social species, such as birds, cats, rodents, and rhesus monkeys. It has been shown that the learning model’s expressions of distress (facial fear expression in primates) can serve as a powerful US. In a seminal series of experiments, Mineka and others (e.g., Mineka and Cook 1993) showed that cage-reared rhesus monkeys quickly acquired a long-lasting fear response toward snakes after as little as one episode of observing a conspecific’s fear response toward the snake. The relationships between the strength of a learning model’s expressed distress, the observer’s immediate response to the model’s distress, and the resulting fear learning in the observer at a later point were comparable to the relationship reported between US, UR, and CR in classical fear conditioning. These and subsequent studies, predominantly in rodents and humans, support the view that observational fear rely on learning processes similar to those underlying classical conditioning. 2. Based on clinical observation, Rachman (1968) and Bandura (1969) suggested that observational and instructed fear learning needed to be added to classical conditioning as important routes to the development of phobias. Supported by an extensive literature on retrospective reports of the antecedents of phobias, this research has been producing viable experimental models of phobic fear acquisition through both observational and instructed fear. These have recently been used to learn more about how specific anxious populations (e.g., phobic and anxiety patients) respond to socially transmitted threats. 3. Since the 1960s, experimental research on healthy humans by social and biological, and more recently developmental, psychologists have provided independent support for the idea that classical conditioning processes might be partly responsible for SLoF. Importantly, this line of work has also emphasized that social fear transmission in humans is dependent on social characteristics of the model or instructor (e.g., emotional expressions and spoken language), which has shown to affect the ensuing learning. Early studies of observational fear learning demonstrated that the learning is dependent on the attribution of emotions and behavioral dispositions to the model during the learning procedure (e.g., Berger 1962). Important Scientific Research and Open Questions Current research on SLoF study both humans and nonhumans to explore unanswered questions remaining from past experimental research. This research has continued to use measures of behavior (e.g., avoidance), cognitions (e.g., verbal expressions), and psychophysiology (e.g., skin conductance and potentiation of the eye-blink startle reflex) in both healthy subjects and patients (e.g., Askew and Field 2008). SLoF has also been investigated by more recently developed methods of neuroimaging, such as functional magnetic resonance imaging (fMRI) and eventrelated potentials (ERP), as well as with the help of pharmacological manipulations and genotyping in both humans and nonhumans (e.g., Olsson and Phelps 2007). In light of these new developments and past research, it is now widely believed that SLoF shares many features of classical conditioning. For example, in observational fear learning – like in classical fear conditioning – the observer’s learned response (conditioned response, CR) to the CS is not of the same kind as the unconditioned response (UR) to the model’s emotional expression (the social US). Rather, research suggests that there is an overlap between the observer’s and the model’s UR and CR, respectively. Moreover, fear acquired through both observation and verbal instruction is expressed through the same brain Social Learning of Fear systems (critically including the amygdala) and peripheral neural systems. Much research has been spent on investigating the significance of the model in observational fear learning. In the past, the view that the model’s emotional expression constitutes an US has been questioned. At least two alternative explanations exist: (a) the learner’s acquired fear might be due to attention to the model’s US rather than the model’s responses per se and/or (b) a result of social inference, in which the model’s fear expression is a CS (and not an US) that was previously associated with a directly experienced aversive event (US). Research in both humans and nonhumans showing that the learner’s UR is present in the absence of the model’s US, and the fact that the learner’s UR in observational fear learning shows characteristics similar to the analogous response in classical conditioning argues against (a) and (b), respectively. Adding to the view that SLoF relies on the same learning processes as direct learning procedures is the view that social cognitions also play an important role in the learning. Research has demonstrated that human learners do not need to observe the model’s expression of fear to acquire a fear response. Vicarious fear learning is dependent on the observer’s interpretation of the model, as well as the learning context. Research on vicariously instigated emotions and empathy has described how an observer’s emotional response to a distressed other is dependent on the observer’s bond to the other individual. For example, a potential future competitor or someone who has defected in a previous social game elicits less empathy (and in some cases even reward-related responses) in the observer. However, it is unknown how these variations in instigated emotions are affecting the observer’s learning. Recent research using neural measures in human and nonhuman animals supports the view that observational and instructed fear learning partly rely on the same neural processes as classical conditioning, but that these processes are modifiable by social cognitive processes (Olsson and Phelps 2007). Current research has begun to investigate the role of mental attributions to the learning model (or instructor) in SLoF. A growing understanding for the neural mechanisms of mental state attributions, such as the attributions of intentions and emotions, as well as the increasing mapping of the processes underlying empathy are likely to S 3115 enable a better appreciation of the role of social cognitions in SLoF. Continued research on SLoF is likely to enhance our understanding for two related fundamental questions related to its nature; what are the specific contributions to SLoF by (1) data-driven (perceptual) information and top-down (abstract) information, and the interaction of the two; and (2) mechanisms of classical conditioning and social cognition and the interaction of the two. The enhanced understanding of the specific mechanisms of different kinds of SLoF (such as observational and instructed fear learning) will underscore the importance to study how these forms interacts among themselves and with other pathways to fear, such as classical fear conditioning, and anxious dispositions believed to underlie the development of anxiety disorders. Another important question for future research will be to explore fear learning through the observation of others’ instrumental actions. This would constitute an indirect learning analogue to instrumental conditioning in which punishments of others actions can produce avoidance and fear.

BERGE2 1 Continuing & Professional Studies - English Language Institute, University of Maryland Baltimore County (UMBC), Baltimore, MD, USA 2 Department of Education, University of Maryland Baltimore County (UMBC), Baltimore, MD, USA Synonyms Observational Learning; Social Cognitive Theory Definition Social learning theory, or SLT, is predicated on the notion that learning occurs through social observation and subsequent imitation of modeled behavior. According to SLT, humans learn from observing the actions and resulting consequences of others. By doing so, individuals can learn to imitate the observed behavior, and thus reap the rewards, or they can learn not to imitate a particular action and thereby avoid the disagreeable consequences. Often seen as a bridge between both behaviorist and cognitive learning theories, social learning theory involves reciprocal interaction between cognitive, behavioral, and environmental influences (Pajares 2002). Theoretical Background Associated most notably with Albert Bandura, SLT has its roots in Rotter’s Social Learning and Clinical Psychology (1954, for related content see http://psych. fullerton.edu/jmearns/rotter.htm). A quarter century later, Bandura expanded and refined Rotter’s ideas in Social Learning Theory (1977). SLT is also related to Vygotsky’s social development theory (1978, for related content see http://tip.psychology. org./vygotsky.html). SLT posits that learning best takes place in social contexts through observation, imitation, and modeling. At its inception, social learning theory challenged the traditional principles of behaviorism and its perceived limitations as a learning theory. It called into question whether true learning could only result from the experiences of reinforcement or punishment, which was the prevailing behaviorist view of the time. Social learning theory also deviated from the basic tenets of behaviorism by espousing the importance of cognition, which had been excluded from the central ideas of behavioral theories, and by supporting the major role that cognitive approaches play in learning processes. Social learning theory is based on Bandura’s premise that learning does not always occur as a result of firsthand experiences alone, but through harnessing the power of observation and imitation (Martinez 2010). Bandura states that through observing others, humans have the capacity to develop ideas about how new behaviors are performed. This information is then coded, stored into memory, and serves as a guide for action either immediately after the observation or for use on later occasions. The four major components, according to Bandura (1977), that comprise observational learning or modeling include: 1. Attention – In order for learning to take place during observation, individuals must pay attention to the modeled behavior. Characteristics of both the observer and the person being observed (the model) can influence how much attention is given to the modeled activities. For example, an observer who is sleepy, sick, or otherwise distracted will not likely have the same level of attentiveness as an observer who is completely focused on the model. 2. Retention – If individuals are to learn from observed behavior, they must, in turn, remember the modeled activities. Retention and recall can be aided through the use of imagery and descriptive language, thus increasing the likelihood that the modeled behavior can be reproduced by the observer. 3. Reproduction – At this stage, the observer translates the modeled behavior into their appropriate individual actions. Reproducing the observed behavior involves converting the retained imagery and language, provided by the model, into a response that is in line with the modeled pattern. Behavioral reproduction improves as the observer practices the new behavior. 4. Motivation – Reproducing observed behavior requires some motivation to do so. Without some reason for imitating the modeled behavior, it is unlikely that individuals would make the effort. Although the cornerstone of observational learning is attention, memory, and motivation, Bandura began to add to his work on modeling by also exploring the cognitive concept of self-efficacy beliefs as they relate to advancing the understanding of human behavior Social Learning Theory (Martinez 2010). Self-efficacy is the belief in one’s own capabilities. These beliefs can significantly influence one’s environment and outcomes, and often determine whether or not someone is able to successfully perform specific actions (Foster 2006; Martinez 2010). Bandura’s focus on self-efficacy pushed his social learning theory deeper into the cognitive realm; thus, “He coined the term social cognitive theory, holding that a person’s behavior, environment and inner qualities interact, rather than one of them being predominant in explaining how people function” (Foster 2006, para. 10). Important Scientific Research and Open Questions Before the advent of social learning theory, behaviorist theories influenced the ways in which learning (i.e., behavior) was viewed. As the basic tenets of behaviorism were called into question, however, particularly those relating to reinforcement, punishment, and the exclusion of cognitive approaches, other views about learning began to emerge and directly challenged the foundation of behaviorist perspectives (Martinez 2010). Albert Bandura, whose name has become synonymous with social learning theory, was one of the first to expand on the earlier ideas that cognition, and not merely behavior, is an important element of learning. In fact, according to Martinez (2010), Bandura’s social learning theory requires neither obvious behavior on the part of the learner, nor any reinforcement or punishment, all of which are associated with behaviorist theories. The learning actually takes place through social observation. A prime example of social observation at work is Bandura’s Bobo doll experiment. During the experiment, children were exposed to both aggressive and nonaggressive models that played with the dolls either violently or placidly. The results revealed that the “subjects in the aggression condition reproduced a good deal of physical and verbal aggressive behavior resembling that of the models. . .” (Bandura et al. 1961, Results section, para. 1). The same was true for the subjects exposed to nonaggressive models. In other words, the children who were exposed to the nonaggressive model imitated similar nonaggressive behavior when playing with their Bobo doll. This experiment revealed that merely observing the behavior of a model was enough to influence behavior, especially among children (Bandura et al. 1961, as cited in Martinez 2010). This S idea of observed/modeled behavior, particularly as it relates to influencing children’s behavior, has sparked questions over whether exposure to violent/aggressive imagines in today’s media (news, television programs, movies, video games, and social networks, to name a few) actually causes aggressive behavior in children. According to Kevin O’Rorke (2006), mass media plays a highly influential role in today’s society, and thus, exposure to models represented in the media can have a powerful impact on shaping human behavior, especially aggressive behavior in children. In fact, research has shown that exposure to televised violence can increase children’s aggressiveness within their lifetime, thus illustrating the significant role that social learning theory plays in influencing behavior and learning through observation (O’Rorke 2006). The work of the early pioneers of SLT has sparked more recent research in how social learning theory relates to such diverse areas as criminology and deviant behavior, advertising and consumer behavior, health and exercise, as well as technology and social media, to name a few. Currently, as SLT relates to criminology and deviant behavior, researchers continue to expound on the earlier work of Edwin Sutherland, Robert Burgess, and Ronald Akers. For example, Brauer (2009) states that through SLT, we can better understand how individuals learn criminal and deviant behavior, which is learned in much the same way as noncriminal behavior. In other words, through associations or social interactions, over time, with those who serve as a model for criminal and deviant behavior, individuals can learn to imitate the observed behavior, particularly in the absence of opposing positive influences or models to the contrary. Whether the deviant behavior is imitated or rejected by the observer is a result of either directly or vicariously experiencing the rewards or punishments of the modeled behavior. Furthermore, researchers are presently examining SLT as it relates to advertising. Specifically, Kinard and Webster (2010) have explored the impact of advertising and Bandura’s self-efficacy construct on unhealthy consumption behavior of adolescents, namely, their use of tobacco and alcohol consumption. Advertising has long been thought to have a significant influence on individual behavior by using favorable stereotypes that are attractive, successful, and healthy. These positive images are widely used to depict essentially risky and unhealthy consumer behaviors, such as smoking and 3117 S 3118 S Social Network alcohol consumption (Pechmann and Knight 2002; Pechmann and Shih 1999, as cited in Kinard and Webster 2010). Adolescents tend to be particularly susceptible to these images, and thus are especially open to initially engaging in smoking cigarettes and drinking alcohol as well as maintaining these behaviors throughout adolescence and into adulthood. Moreover, advertising has been shown to act as an additional model of behavior that reinforces the social influences of adolescents’ parents and peers who smoke and drink. The added reinforcement provided by advertising increases the likelihood that the observed behaviors (i.e., smoking and drinking alcohol) will be imitated by adolescents. Researchers continue to examine the established tenets of social learning theory and its application across a broad spectrum of areas, and the basic principles of SLT continue to hold true. In other words, to one degree or another, a great deal of individual learning takes place within a social context through observing and eventually imitating the behavior (positive or negative) of others. Although other complex factors, such as self-efficacy and the perceived rewards and/or punishments of the behavior, can influence the degree to which, if at all, the modeled behavior will be imitated by the observer(s), research (past and present) has shown that regardless of the domain, observation plays a powerful role in the learning process.

From simple graphs and trees to complex networks, these relationships can be visualized, factor analyzed, or implicit, but they offer educators new insights into the sometimes hidden attitudes, motivation, knowledge, and the ability of their students, parents, peers, and beyond in informal and commercial settings. Educational networking uses social network technologies for educational purposes. Theoretical Background As this is written, social network sites throughout the world are increasingly popular: some (such as Facebook) have become the most visited sites on the Internet. These are sites where friends and acquaintances (and some strangers) share daily and even minute by minute updates on their activities, interests, plans, and attitudes. They comprise Wikis and Blogs and photo galleries and games and short messages. Students are known to stay up all night sharing their tweets and messages. Since this phenomenon has arisen dramatically in the last few years, it is not surprising that so far it has had little impact on teaching and learning. As a result, this short article is short on research findings and conclusions and long on speculation. Social Networks and Students Many authors have suggested ways to adapt students’ existing habits on social network sites to the S 3119 educational realm; for instance, such habitual activities as messaging each other, checking each other’s profiles, and browsing upcoming parties might all be adapted to education. The most frequent and self-evident suggestion for educators thinking about how to use social networks in education is to reach out to students and invite their participation in asynchronous and synchronous discussion groups on these popular sites. Participation and engagement could be encouraged with incoming classes, such as college applicants, or in classes of already enrolled pupils. The central idea is that this engagement could motivate and support students and increase their likelihood of staying through to graduation, and promote more interchange of ideas in the classrooms. Boosting engagement has been shown to have a clear effect on how well-integrated students feel within their social and academic environments. However, it is still very unclear how well students’ social networking habits translate directly to teaching and learning environments. In particular mentoring students with feedback and advice may be just as time consuming as face-to-face mentoring, and less effective. Peer to peer sharing and support may be more easily exploited for education, and that may already be happening without formal educational support. On the negative side, social networks have the potential to distract students, and fill their academic time with an overabundance of irrelevant detail, and possibly even encourage cheating among classmates. Social Networks and Teachers Within many popular social network environments many sites have grown up to link faculty and students, or faculty to faculty. If this continues and remains successful beyond the initial flurry of creative excitement, these sites could serve many purposes such as continuing professional development, mentoring, and enrichment. One such site reports that in a first year reading program, they have had over 100 staff, faculty, and students join. However, it soon became a not very active page, despite what was thought to be attractive and inviting discussion threads. Students did not really talk to each other on the site, and it became apparent that educators may overstate the usefulness of social networking technology for teaching. Other sites are building social networking software designed especially for education, designed from the S 3120 S Social Networks Analysis and the Learning Sciences ground up to support learning. The main difference is that these sites are not a centralized service. Whereas most commercial networks are one space branded in one particular way, special purpose education social network sites will allow organizations to host their own systems customized to their specific requirements, but still retain connectivity from site to site. This is an attempt to build a truly distributed learning landscape which allows for local networks of personal acquaintances, with the wider benefit of being able to make relevant connections across sites. Social Network Analysis (SNA) At the same time as social network, Internet sites have become increasingly popular, the technology and statistics of social network analysis (SNA) has matured. A brief description of these tools is provided, followed by a short analysis of their use in education. For research purposes several free public domain SNA programs are widely available but specific tools and environments for educators to display their students’ social and knowledge networks are not yet widely available. Definitions Several concepts haven proven useful in the SNA of educational groups. Centrality: This measure indexes the representativeness and proximity of a node to all other nodes. The most popular and well-connected person would have high centrality, high degree, and high closeness. Degree: The number of links to other nodes in the network. Indegree and Outdegree measure the number of links from and to others, respectively. Important Scientific Research and Open Questions In research on social networks in the learning sciences often only the easiest metrics with simple tools are analyzed. For instance, the density of a network is at a maximum when all the nodes are connected to each other. However, there is a confounding with size. The larger a group is, the harder it is for the network to be fully connected, with everyone linked to everyone else. However, if density is an important measure for how well a class is interacting with each other, it must somehow be normalized on class size, making the density measure more complex and creating a difficulty for how to normalize it. Increasingly, social networks are being computed not directly from surveys of students’ preferences, but instead from communication data in virtual environments, commercial social network sites, help and advice networks, and preference networks in online purchasing and rental stores. For instance, an affiliation network of students can be computed from conversation threads. Two social networks can easily be derived from the same discussion group: a participant network that shows the connections among students who have participated in the same conversation threads, and a network of threads that have common students. Each provides information about students’ interests and abilities. Within these networks the flow of knowledge and its increase with teaching and learning can be assessed with more complex analyses. Expertise and trust have been measured in online discussion environments and diverse question-answer forums. In these, people network with each other to share their expertise, technical knowledge, advice, and opinions. Research has revealed that experts tend not to reserve their expertise for the really difficult questions, but instead answer more questions than others, including the simple questions. As attributes of experts are uncovered in this research, guidance can be formulated for teachers to better understand how to encourage students to provide and seek advice and become experts in their domains of personal interest. Social Network Principles and Findings As a young science drawing from many disciplines, SNA has few general findings that illuminate education and learning. Here are two potentially useful insights that SNA has produced. Dunbar Number. Research has suggested that there is a limit to the number of people who can be understood well enough to be called friends and be part of a community. Because of the complexity and great number of variables that need to be understood about a person to call them a friend, the cognitive load of developing a complete mental model of each limits their number to about 150. One can see this limit in operation in the social network data of many organizations: a company in the army, a community neighborhood in a city, and the size of villages in agricultural communities. Social Psychology of Music Instruction and Learning Small World: Early experiments using mail systems discovered that any person on the US East coast could be found from the West coast using five or six intermediary people who each knew each other personally. This has been encapsulated by the phrase: “six degrees of separation.” More recent explorations of the phenomenon using email arrive at very similar results. In comparison with the hub-based structure of Internet servers, where certain sites, such as Google or Facebook have a preponderance of links, the links among people are much more evenly distributed, but both distributions may be best described by power laws.

Social Norms ▶ Culture in Second Language Learning Social Practices Social practices are the means by which people participate in cultural activities.

Synonyms Social psychology of music; Social psychology of music education Definition Social psychology of music instruction and learning is the study of relationships among individuals, groups of individuals, and the society in music instructional and learning contexts. It contains a tradition in psychology, which tends to focus on the effect of social factors on individuals, and a tradition in sociology, which tends to view individuals within a larger social network. Since the vast majority of music instructional and learning activities involve two or more individuals in a social context, this is an enormously broad area of study that covers many aspects of such interactions and relationships. Theoretical Background Social psychology of music instruction and learning developed as a parallel with social psychology since the early part of the twentieth century. This was mainly due to the work of Paul R. Farnsworth (1899–1978), who was trained as a psychologist but with an intense interest in music and a strong desire to work with S 3122 S Social Psychology of Music Instruction and Learning musicologists, and later with music educators (LeBlanc 2001). He published many music articles in psychology journals since the 1920s. Since the late 1930s, his work began to appear in music journals. His last book, The Social Psychology of Music (first published in 1958, second edition in 1969), was seminal in establishing the field of social psychology of music. His work covered many different topics in this field. The most extensive and well-known ones were musical eminence and musical taste. Other social psychologists, such as Daniel Berlyne (1924–1976) and David Hargreaves (1948–), built upon the work of Farnsworth and consolidated the field of social psychology of music. Berlyne was known for his experimental aesthetics which suggested an inverted-U relationship between liking and certain qualities of the stimuli, such as complexity. Hargreaves and Adrian North coedited a book, The Social Psychology of Music, published in 1997 and coauthored another book, The Social and Applied Psychology of Music, published in 2008. Also, McDonald, Hargreaves, and Miell coedited a book in 2002 titled Musical Identities. The tables of contents of these books reflected to some degree the scope of the field. Hargreaves and North (1997) covered the areas of individual differences, social groups and situations, social and cultural influences, developmental issues, musicianship, and real world applications including education, therapy, and commerce. North and Hargreaves (2008) included the areas of composition and musicianship; musical preference and taste; “problem music” and subcultures; music, business, and health; and musical development and education. McDonald and others (2002) addressed how musical identities were developed in the school and family environments and in various age-groups and performance contexts. It also tackled how identities were developed through music in different gender, youth, and national groups. Music educators saw the relevance of Farnsworth’s and other social psychologists’ work and expanded on the concept of social psychology to include specific situations applicable in music instruction and learning. These music education researchers included Harold F. Abeles in sex-stereotyping of musical instruments, Ed Asmus in music attribution, Manny Brand in parental involvement in music learning, Lucy Green in informal learning in music, Albert LeBlanc in music preference, Anthony Kemp in music and personality, Charles P. Schmidt in applied music instructions, and so forth. Below are highlights of current interests in some of these areas. Identity has become an important topic in music education research. Adding to the complexity of the topic is the idea that there are differences among individuals, which entail many variables relevant to music instruction and learning. Such different variables include sex, age, ethnicity, culture, personality, and so forth. The literature suggests that these variables not only have an impact on musical development and musical responses, but also help shape how music learners perceive themselves as music makers. Another layer of musical identity issues is the disconnect between music learner identity and teacher identity. Roberts (2010) cites the path of a music teacher, from being solely a performer to being primarily a teacher of performers, as being a source of concern for the music education profession. Other authors have explored the possibility that being a musician and a music teacher might include performing different diverse roles including composer, improviser, producer, or conductor. Along with this emerging strain of research is the idea that for much of the history of music teaching and learning, performance has been the primary mode of music instruction, to the neglect of other modes of music making, such as composition, improvisation, various forms of small-group music making, and the inclusion of various musical styles that do not go along well with the traditional composing-performing-listening sequence. Collaborative music making and simultaneous composing-performinglistening modes have led to a new set of identities for both the learner and the instructor. Social psychologists in music have also considered the role of the instructor and learner within the large ensemble – band, choir, and orchestra – setting. These researchers in music education often cite McCall and Simmons (1966) coauthored book Identities and Interactions: An Examination of Human Associations in Everyday Life, to account for the interactions of various identities within these settings. Attribution of success and failure in music has been another important topic guiding the work of music education researchers. Some have applied Albert Bandura’s social learning theory, Bernard Weiner’s attribution theory, or Edward L. Deci and Richard M. Ryan’s Self-Determination Theory to music studies. Others have used James Connell’s self-system processes Social Psychology of Music Instruction and Learning to account for motivation and persistence in music. Within Connell’s theory, self-system processes are divided into three groups based on the following psychological needs: 1. Competence: Including strategies – knowing what it takes to do well, and capacities – possessing the skills to do well. 2. Autonomy: Including self-regulation – wanting to do well because doing so has personal meaning. 3. Relatedness: Including self – accepting and caring about oneself, and others – feeling accepted and cared about by others. These processes are carried out in social settings and, therefore, have a number of interesting layers. Some researchers extend these layers to include school community, regional identification, nationality, and global perspectives. One could easily find social psychology of music instruction and learning crossing over with other subfields of psychology and other neighboring fields, such as sociology and anthropology. ● Which factors contribute to differences in musical behavior among members involved in a music teaching and learning setting? ● What is the role of gender in music instruction and learning, given the rapidly changing social climate and availability of various technologies? 3123 ● What is the effect of a single-sex music instruction ● ● ● ● ● Important Scientific Research and Open Questions Scientific research in the field may be analogous to a kaleidoscope. Researchers, be they psychologists or music educators, tend to study topics that they see most relevant and important. As the field continues to develop, psychologists, musicians, and educators should continue to be more aware of each other’s work. They might learn from each other’s theories, perspectives, methodologies, and findings. Questions that remain open include those that are based on value judgments. For example, what role should music preference play in the music instruction and learning process? How should individuals determine for themselves what musical diet is most appropriate for themselves? To what extent should some people, such as music instructors, have authority over others’, such as music learners’, musical choice? Open questions that could be subjected to empirical observations include: S ● and learning environment compared to that of a coeducational environment? What theories are best in explaining the attribution of success and failure in instruction and learning specific to music? Based on a current assessment of how and by which means adolescents identify with music, how might the traditional roles of music teachers change to better reach the twenty-first century adolescent music student? Which genres of music and which modes of music making present the greatest potential to reach the adolescent musician and beyond? What theories are best to account for the manifestation of identity within the teaching and learning of music of both teacher and students? What sort of power struggles take place in the instruction and learning setting of music among peers, teachers, parents, and the larger school community? How do students perceive the role of the ensemble director in the learning exchange? How does the director perceive the role of students in the learning exchange? How do these perceptions interact? What implications do these interactions have for music instruction and learning in each particular setting? How have musical experiences outside of educational institutions contributed to the learning of music within these institutions, and vice versa? Furthermore, much research in the social psychology of music instruction and learning has been focused on studying the first 20-some years of live of the study participants. Researchers are still exploring the roles music plays beyond the early adult years and into the final years of life. Given the lengthening life expectancy, many may continue to learn and experience music and find meaning in it for half a century or more beyond the first 20-some years.

EVERGREEN, CHRIS L. S. CORYN The Evaluation Center, Western Michigan University, Kalamazoo, MI, USA Synonyms Emotional intelligence; Emotional quotient; Socialemotional competence; Social intelligence Definition The Social-Emotional Learning Scale (SELS) is a 20-item questionnaire that measures the latent constructs Task Social-Emotional Learning Scale S Articulation, Peer Relationships, and Self-Regulation through self-report. It is designed to assess socialemotional learning in late elementary students (ages 9–11 in the USA) to inform needs assessment, program planning, and evaluation. Respondents endorse items on a five-point scale, which ranges from strongly disagree to strongly agree. The SELS instrument is a mixed model, in that it taps into both personality and intelligence constructs. leaving researchers and program planners without the ability to meaningfully measure their findings against other programs with common objectives. Therefore, while measures of social-emotional learning are prolific, they are generally insufficient for the purposes that the SELS sought to address. Theoretical Background Operationalization of social-emotional learning is still a subject of debate. Some scholars believe that what is labeled emotional intelligence is a product of mental processes, in other words something that can be learned. Such theories are bolstered by Gardner’s Multiple Intelligences, in which interpersonal and intrapersonal intelligences describe social-emotional orientation (Gardner 1983). However, tests of discriminant validity have failed to show the construct as operationally distinct from others, such as verbal intelligence (Caruso et al. 2002; Ciarrochi et al. 2000; Roberts et al. 2001). Other theorists disagree with the notion that intelligence is the basis for one’s level of social-emotional understanding, suggesting instead that it is a trait of one’s personality, such as aggression or empathy (Bar-On 1997). While considerable research has been conducted to investigate the distinction, definitive evidence is not yet available. Whether it is a component of intelligence (i.e., something than can be learned) or personality (i.e., something innate), or some combination of the two, remains an open question for further research. Social-emotional learning (SEL) refers to a child’s ability to “recognize and manage emotions, develop caring and concern for others, establish positive relationships, make responsible decisions, and handle challenging situations constructively” (CASEL 2008, p. 1). The SELS instrument was created to assist program planners and evaluators in selecting an aspect of SEL as a programmatic focus for populations of late elementary students using reliable and valid measure. The need for a common tool for curricula or program planning is clear, because the instruments typically used to address social-emotional development through these avenues are dispersed. Program evaluations of well-regarded SEL interventions have typically designed instruments particular to the given program, whether they address comprehensive or specific aspects of SEL, and regardless of whether they are in a needs assessment or program evaluation stage. The development of the SELS is based in the work of the Collaborative for Academic, Social, and Emotional Learning (CASEL), which acts as a bridge between the theoretical and practitioner worlds. CASEL was a reference for the four states that developed SEL guidelines for education and from which the items for the SELS instrument were developed. Yet, even with major theorists in collaboration with CASEL, their list of suggested assessment tools did not address program planning needs for a general education audience. The SELS was designed as an improvement of existing instruments, which tend to overfocus on specific individual deficiencies or come buried in a larger school climate survey, by providing a more general tool having evidence of validity and reliability. Creating a program-specific instrument, even if culled from a combination of existing instruments, is both costly and time consuming. Moreover, in such situations, instruments are not norm-referenced, 3125 Important Scientific Research and Open Questions Cross-References ▶ Emotional Intelligence and Learning ▶ Emotional Learning ▶ Learning by Feeling ▶ Learning the Affective Value of Others ▶ Socio-Emotional Aspects of Learning References Bar-On, R.

Socialization ▶ Enculturation and Acculturation ▶ Extraversion, Social Interaction, and Affect Repair Socialization of Intelligence ▶ Social Construction of Learning Socialization-Related Learning THOMAS G. REIO, JR. Department of Leadership and Professional Studies, Florida International University, Miami, FL, USA Synonyms Academic socialization; Adaptation; Informal learning; Social competence; Workplace learning Definition Socialization in its broadest sense is the process where inexperienced individuals are taught the skills, behaviors, norms, attitudes, values, and motivations required to be able to function competently as a member of a culture. Socialization entails transmitting culture from one generation to the next, counting training and development activities linked to specific tasks or roles in groups, organizations, and occupations (Maccoby 2007). Socialization-related learning, then, is the learning associated with becoming a functioning member of a culture. Theoretical Background Socialization encompasses a wide variety of activities that influence the thinking and behavior of novices that result in important societal outcomes. An important consideration is the proactivity of the individual to learn what is necessary to adapt and fit in to a culture, and continuously so over time. Without proactively learning during the socialization process, the novice is far less likely to acquire the information necessary to learn how to think and act in accordance with cultural norms. The learning associated with being socialized, i.e., socialization-related learning, is a curiosity-driven process where individuals seek the new information needed to situationally perform specific tasks and roles in light of cultural norms and expectations (Reio and Callahan 2004). Curiosity, the desire for new information and sensory experiences, stimulates observation, consultation, and directed thinking types of exploratory behaviors (Berlyne 1960). Because individuals should not expect to be merely taught what they need to know on a consistent basis, he or she must be proactively curious and exploratory if they ever hope to learn how to be and remain a fully functioning member of a culture. Although formal learning in classroom settings, for example, can be useful for facilitating socialization-related learning (e.g., a children’s lesson on how to behave properly in a museum and other public places) socialization-related learning occurs through engaging in mostly informal learning types of activities, including coaching and mentoring, trialand-error experimentation, reflection, self-directed study, etc. With children, parents are considered to be primary socialization agents where they teach the appropriate social skills, attitudes, and behaviors to be able to continuouosly adapt to a culture, serving ultimately as a determinant of being an independent and successful adult (Taylor et al. 2004). In school settings, both parents and teachers are the primary academic socialization agents that shape children’s thinking, behavior, and academic success through supporting positive school experiences. To be sure, however, there are a number of other socialization agents or sources of information and learning that influence children’s Socialization-Related Learning socialization-related learning and successful socialization-related outcomes. Older siblings, peers, mass media (e.g., Internet, Twitter, podcasts, wikis, television, and magazines to name a few), and neighborhood contexts also serve to shape children’s thinking and behaviors related to performing well in school. Again, children must be proactively curious and exploratory about their environment in general if they hope to learn and adapt to the daily contingencies associated with being a successful member of their culture. For adolescents, parents and teachers continue to be powerful socialization agents, yet peers can also be quite influential during this time (Ryan 2001). As with children, mass media, older siblings, and neighborhood contexts can impact adolescent socialization, but work contexts contribute to their socialization as well. At school, peers communicate expectations for valued forms of behavior. For example, most middleclass adolescents report that peers convey expectations of cooperativeness and helpfulness in classroom settings and engagement at least to some degree in prosocial behaviors like volunteering outside of school. Peers also influence educational goal setting for academic accomplishment and other positive forms of behaviors. The possibility always remains though for peers to negatively influence socialization-related outcomes. Those who have not successfully navigated the socialization process are less likely to have proactively sought the information needed to fit in and function well at school. As a result, such adolescents are predisposed to being socially rejected by their peers and apt to being less adjusted and more withdrawn than many of their classmates (Wentzel and Looney 2007). In adulthood, individuals continue the socialization-related learning useful for adapting to societal demands consistent with this stage of the lifespan. Friends, peer groups, romantic and social partners, media, and workplace contexts serve as socialization agents during this time. Through socialization-related activities, adults learn how to make productive relationships with family and friends, take on coaching and mentoring roles, assume positions of leadership, and acquire a sense of themselves as independent, competent societal members. These endeavors require being proactively curious and exploratory to learn and adjust to life’s challenges and stressors. Socialization-related learning suffers when a culture does not embrace such information seeking. S 3127 In workplace settings, socialization helps organizational “outsiders” become organizational “insiders.” The socialization process applies not only to organizational beginners like apprentices and trainees, but also experienced workers at a company who are newcomers to a workgroup or new facility. Further, socialization occurs when workers get a new supervisor or attend school. In other words, the socialization process in organizations is a continuous one, regardless of one’s organizational status, experience, or time on the job. Socialization-related learning allows workers to adapt to evolving contingencies in their work environment by facilitating their adjustment to the organization’s values and norms, clarifying role identities, developing job- and performance-related skills and capacities, and helping them learn to whom to turn for the information needed to interpret organizational uncertainties (Reio and Callahan 2004). This process by which organizational members learn and adapt to their workplace surroundings has been found to be consistent in union and nonunion, profit and nonprofit, and government and nongovernment settings. Important Scientific Research and Open Questions Mounting research evidence supports the relevance of socialization-related learning to adapting to challenges and opportunities presented by striving to be a competently functioning member of one’s culture across the lifespan. A number of socialization agents have been identified (e.g., teachers, peers, parents, mentors), but an understanding of the agents’ degree of salience during specific stages or phases of the lifespan remains unexplored. Moreover, there is not simply a one-way transfer of information from these agents to those who are less experienced. For example, mentors impart important information to mentees concerning career and social development issues, yet mentees also contribute their insights and prior knowledge into enriching the mentor’s understandings of these same organizational issues. It is likely, therefore, that there exists a bidirectional learning relationship between those who are more and less experienced. More complete understandings of the socialization process will require acknowledging this bidirectionality in research designs. Finally, it is clear that proactive information seeking in the form of curiosity and exploration is a key component of the socialization process S 3128 S Socially Biased Learning as it motivates learning and adaptation, yet researchers have little sense of how and to what degree to promote this proactivity across a broad range of environmental settings.

Socio-Constructivist Models of Learning VASILIKI K. SIMINA University of Manchester Institute of Science and Technology (UMIST), Manchester, UK Thessaloniki, Greece Synonyms Sociocultural model; Sociological model Definition The term is used to describe instructional design models drawing from the learning theory of social constructivism. Since learning is considered to be an active process with the learners constructing their knowledge on their own based on experience and reflecting on this experience, social constructivism focuses on the social and cultural context which shapes the construction of knowledge. Theoretical Background Socially Biased Learning ▶ Social Learning in Animals Socially Transmitted “Memes” ▶ Animal Culture Society of Mind ▶ Schema-Based Architectures of Machine Learning Teaching and learning theory has seen a paradigm change in which the learner becomes the center of learning and does not passively receive knowledge. Consistent with that direction is social constructivism, which is a variable of the well-known theory of constructivism. The basic tenet of constructivism is that individuals construct their knowledge on their own by associating new with prior information through their interaction with their social and physical environment and by reflecting on their experiences. Elements of the constructivist theory can be detected not only in the antiquity (e.g., in Socrates’ maieutic method) but also in discovery or experiential learning. However, the theories of Jean Piaget and Lev Vygotsky are the most influential for the structure of cognitive and social constructivist theory respectively. Socio-Constructivist Models of Learning Piaget (1953) focused on cognitive development and developed a theory of the different cognitive stages children come to know the world. He asserted that mind has mental structures, called schemata, which are modified and enlarged and which then become more complicated with mental development through the processes of assimilation and accommodation from infancy to adulthood. Learning, here, is based on discovery, experience, and the predisposition of the individual to adapt to his environment, something which he struggles to succeed by establishing equilibrium between schemes and the environment. With Vygotsky (1978), the emphasis is not only on the cognitive aspect of learning, but also on the social one because the individual cannot be separated from the society and, therefore, thinking develops under particular sociocultural conditions. One of his fundamental ideas is that cognition develops out of social interaction and negotiation of meaning. In that sense, the construction of knowledge is a shared, rather than an individual, experience. Through dialogue, information is transmitted helping the individual to internalize knowledge, thinking to be developed and learning to occur. Language, which is socially and culturally oriented, plays a significant role in this process since it is the necessary tool for conveying and negotiating meaning. In addition, the notion of the “zone of proximal development” is basic in the social construction of understanding because through the process of scaffolding the learner is guided in such a way so as to perform at a level beyond the one at which he could perform on his own. Therefore, social interaction promotes collaboration for learners to achieve self-reliance (Wood et al. 1976). Another fundamental assumption of social constructivism is that cognitive processes, thinking and learning included, are situated in social and physical contexts. Social interaction is a critical component of situated learning. According to Brown et al. (1989), learners are involved in a “community of practice” which embodies certain beliefs and behaviors to be acquired. They also argue that learning, both inside and outside school, advances through collaborative social interaction and social construction of knowledge. Knowledge is contextually situated and is fundamentally influenced by the activity, context, and culture in which it is used. Therefore, knowledge cannot be taught in abstract but within context. For that S reason, in situated learning knowledge is presented in an authentic context, that is, in settings that normally involve that knowledge. Approaches such as taskbased, project-based, and content-based try to integrate learners in authentic environments. Context is very important for the constructivists who believe that types of learning cannot be identified independent of the content and context of learning. In a socio-constructivist model of learning, it is not only the sociocultural conditions in which learning occurs that should be taken into consideration, but also the social and cultural context which each learner carries within the learning process. All these contexts create a variety of perspectives which learners can have access to through social interaction and negotiation of meaning and help learners construct knowledge on their own. Therefore, learning must be situated in rich, reflective real world contexts for the constructive learning process to occur. Taking all the above into consideration, a socioconstructivist model of learning should consist of the following principles. First of all, learning should be considered as an active process in which the learner is placed in the center while the teacher plays the role of the facilitator or the guide. The learner should be able to make associations with his prior knowledge and experience. Moreover, the focus is on meaning and not on structure. Hence, the learning environment should encourage collaboration, negotiation, and social interaction and foster the sharing of multiple perspectives, providing the stimuli for the construction of knowledge. Therefore, learners should be engaged in context-rich experience based and complex authentic activities, which are meaningful to them, and where authenticity and complexity appear within a proximal range of the learner’s knowledge and prior experiences (Bednar et al. 1992). One type of online application, such as WebQuests (Dodge 1995), is a potential example of good practice of the socio-constructivist model of learning. In WebQuests, learning is situated in authentic environments because they are based on scenarios which create a situation in which the completion of a task is meaningful to the learners. Moreover, learners usually work in groups promoting not only collaborative and cooperative learning, but also the sharing of meaning. WebQuests also support scaffolding since the information is given to the learner little by little through 3129 S 3130 S Socio-Constructivist Models of Learning the different steps of the task, helping him/her gradually become self-reliant. The multimodal aspect of WebQuests provides a wide variety of resources which learners can use in order to construct knowledge on their own. Finally, learners have the opportunity to reflect on what they have learned and discuss possible extensions and applications of the gained knowledge. Therefore, all these characteristics make WebQuests an ideal socio-constructivist learning environment. Important Scientific Research and Open Questions The term “social constructivism” is used in almost every discipline. However, it is remarkable how frequently it appears in the discourse of educational research, theory, and policy, even if it is simply used to characterize any innovative approach to learning where the learner plays a more active role and there is some kind of interaction. Throughout the literature, despite the fact that most researchers are thoroughly engaged with the broad theory of social constructivism and few papers succeed in developing applied models of teaching, the interest is focused on (a) what can be done within the classroom environment, (b) computer-assisted learning, and (c) curriculum theory. To begin with, a general socio-constructivist framework can be effective for teaching students of all ages and levels of ability (Watson 2001). Social constructivism can also provide crucial direction for teacher education since the paradigm shift in education demands the transformation of the traditional teacher. Thus, the socio-constructivist model of learning can be applied in all levels of education, but what is still there to be examined is how effective such a model can be on a long-term level rather than simply within the framework of a project or task. Moreover, computer-based learning seems to be consistent with the principles of social constructivism. Most attention is drawn to the online learning because it fosters collaborative discourse and the individual development of meaning through construction and sharing of texts and other social artifacts. According to Jonassen et al. (1999) multimedia and hypertext can provide a learning environment where learners can construct knowledge on their own. In addition, the use of computer-supported collaboration and communication tools can extend the ways in which students and instructors interact within and beyond classroom. The claims for synchronous and asynchronous online discussions are found to be frequently based on socioconstructivist principles. Chat rooms, blogs, wikis, and podcasts can act as social mediation tools in the learning process because they enable the sharing of ideas and experiences (Chandra and Chalmers 2010). Finally, the scaffolding mechanisms can be effective in online environments such as learning management systems. Therefore, computer technology offers so many potentials for applying the socio-constructivist model of learning leading learners to self-reliance and instructors to the role of the facilitator. Regarding the design of the curriculum, the way students learn needs to be carefully considered and the socio-constructivist model of learning can be an effective way of conceptualizing learning. Over the past years, curriculum theory has worked out many educational implications of social constructivism. Many scholars have suggested the socio-constructivist framework in their claims for curriculum reform in many countries. However, since there is a more holistic approach toward the design of curricula, there are not many curricula that can be merely characterized as social constructivist. For example, in Turkey, there is an attempt but only in subjects related to science (Fer 2009). However, we need to wait for the results of such an endeavor in order to be able to discuss how interactive learning can help learners construct knowledge on their own on long-term practical base. Although social constructivism is a term which is frequently used and teachers try to apply its implications in their everyday teaching, still the role of social interaction in the learning process raises some questions. As Kittleson and Southerland (2004) said, we will always wonder about what the co-construction of knowledge looks like. They claimed that social factors such as status, gender, and leadership style can have an important role in shaping opportunities for knowledge construction, but how can we make sure that the learning opportunities available to students in groups are equally distributed across groups? What happens in the cases where there is competitiveness between learners or unwillingness to participate? Therefore, there must be a clarification of the interaction between learners. It is often presumed that it facilitates learning, but we need to find the most suitable tools in order to measure the learning outcomes associated with participation in social interaction.

The term “sociocultural” (or cultural–historical, or socio–historical) highlights the prominence given in this framework to social, cultural, and historical sources of human development, mind, and learning, in contrast to other theories that either see biological sources of development as primary, or that view experience and environment as having importance but do not foreground social, cultural, and historical contexts. In fact, this approach goes further than taking social, cultural, and historical contexts as influences on learning and development. Rather, for researchers in this tradition, the cultural activity setting itself – rather than the individual learner – comprises the unit of analysis in research. As Rogoff explains, " In contrast to theories of development that focus on the individual and the social or cultural context as separate entities (adding or multiplying one and the other), the cultural-historical approach assumes that individual development must be understood in, and cannot be separated from, its social and culturalhistorical context. According to Vygotsky’s theory, the efforts of individuals are not separate from the kinds of activities in which they engage and the kinds of institutions of which they are a part. (2003, p. 50) Theoretical Background Given this commitment to a holistic unit of analysis, sociocultural researchers of learning examine human activities in cultural contexts, mediated by language and other symbol systems, and developing historically through time. Many different kinds of contexts are explored and considerable attention is given, in this research, to the analysis of contextual specificity to understand human activity-in-context. The sociocultural approach reflects several key themes (Wertsch 1985) articulated in Vygotsky’s work: (a) the social sources of learning and development; (b) the central role of semiotic mediation in human functioning; (c) the importance of genetic analysis. These three themes will be discussed first, followed by several related topics. Sociocultural–historical research views all learning and development as occurring through the processes of social interaction. Any individual development, in its cognitive, social, and emotional aspects, results from the learner’s interaction with others. Thus, the unit of analysis must be social, rather than focused on the individual. Vygotsky captured this idea in his “genetic law of cultural development”: " Every function in the child’s cultural development appears twice: first, on the social level, and later, on the individual level; first, between people (interpsychological), and then inside the child (intrapsychological). This applies equally to voluntary attention, to logical memory, and to the formation of concepts. All the higher functions originate as actual relations between human individuals. (Vygotsky 1978, p. 57) Sociocultural research has explored the workings of social interaction for learning and development in numerous ways, across a range of cultural contexts, for learners of all ages, and in multifarious activities: studies have analyzed the social sources of the earliest language acquisition of infants in interaction with parents in Western professional families (Bruner 1983); the formal and informal apprenticeships of nonschooled children and adults in a variety of traditional and contemporary cultures (see Rogoff 1990); the social sources of highly creative and productive individuals in the arts, sciences, and humanities (see John-Steiner 1985); the peer interaction and collaboration of children in and out of school settings (see Cole 1996; Daniels 2007). As these examples suggest, much of the research has been conducted in contexts of naturally occurring activity (rather than experimentally contrived), in informal settings such as homes or after-school programs, as well as formal learning in schools, and in an impressive range of settings, rural and urban, Western and non-Western. In any of this work, a full examination of context is key. As Rogoff writes, summarizing this view for child development, " [T]he individual child, social partners, and the cultural milieu [are] inseparable contributors to the ongoing activities in which child development takes place. The concept of guided participation attempts to keep the roles of the individual and the socio-cultural context in focus. Instead of working as separate or interacting forces, individual efforts, social interaction, and the cultural context are inherently bound together in the Sociocultural Research on Learning overall development of children into skilled participants in society. (1990, pp. 18–19) For Vygotsky, all thinking and all action are mediated, either by symbols or by tools, or both. Semiotic mediation is the idea that thinking is made possible by the use of symbolic tools, such as oral and written language, in both individual and social functioning; consciousness does not preexist but comes into existence through the use of semiotic tools of various kinds (e.g., written language, musical notation, or the Cartesian coordinate system). In addition, it is the use of these semiotic means that not only contributes to the creation of internal reality, but also connects the external and the internal reality: The use of notched sticks and knots, the beginnings of writing and simple memory aids all demonstrate that even at early stages of historical development humans went beyond the limits of the psychological functions given to them by nature and proceeded to a new culturally-elaborated organization of their behavior. . . . Even such comparatively simple operations as tying a knot or marking a stick as a reminder change the psychological structure of the memory process [extending] the operation of memory beyond the biological dimensions of the human nervous system . . . to incorporate artificial, or self-generated, stimuli, which we call signs. (1978, p. 39) Just as physical tools are directed toward the external world, psychological tools are directed internally, toward the solution of mental challenges. And just as physical tools have been developed through culture and historical time, in the context of specific cultural activities and practices (such as the handheld hoe used in farming), so, too, psychological tools are the products of sociocultural activities and appropriated by individuals in the context of those practices. Studies have examined many processes of mediation, from the impact of oral and written language systems or structures of questioning, to the effect of physical objects or spatial arrangements on memory or calculation (see Daniels 2007; Kozulin 1996). Such appropriation or internalization of “sign-using activity in children is neither simply invented nor passed down by adults” but arises from a series of “qualitative transformations” through a dialectical process (Vygotsky 1978, p. 46). Much research has shown that the forms and functions 3133 of language and other sign systems used in instruction affect learning in a range of qualitative and quantitative ways and for all kinds of learners (see Daniels 2007; Kozulin 1996; Wells 1999). The process of transformation whereby the learner’s participation in an activity shifts from dependence on an adult or more capable peer to initiating his or her own use of some mediator is examined through “genetic analysis.” Genetic analysis refers to the genesis of psychological functions, their origins and history (and is not related to biological issues of heredity). The interest in sociocultural–historical approaches is primarily in the process, rather than the product, of learning and development. Vygotsky wrote: " " S To study something historically means to study it in the process of change; that is the dialectical method’s basic demand. To encompass in research the process of a given thing’s development in all its phases and changes . . . fundamentally means to discover its nature, its essence. . . . Behavior can be understood only as the history of behavior. (1978, p. 65) In the sociocultural approach, learning and development are most often examined in the social and cultural contexts in which they are routinely produced. This approach rejects any universal scheme for understanding learning or development. Rather, psychological systems that unite or separate various functions vary across contexts, in terms of culture, history, and other shared dimensions of human social life. Studies of parents and children engaged in a task such as puzzle-solving for the first time have demonstrated the genesis of the child’s participation in the task, from initial dependence on the adult for guidance to the child as eventual initiator of independent problem-solving (Wertsch 1985). Studies of oral or written private speech (or “speech for the self ”), for example, have documented the use of semiotic mediators and their transformative affects among school children learning math, among adults learning a new language, among creative thinkers in the process of producing and capturing new thoughts (see John-Steiner 2007; Wertsch 2007). Important Scientific Research and Open Questions Vygotsky contrasted his view of learning and development with those of other theories. He saw learning and S 3134 S Sociocultural Research on Learning development as both distinct and interdependent, and he criticized Piaget’s view in which “maturation is viewed as a precondition of learning but never as a result of it” (1978, p. 80). " Learning awakens a variety of internal developmental processes that are able to operate only when the child is interacting with people in his environment and in cooperation with his peers. . . . Learning is not development; however, properly organized learning results in mental development and sets in motion a variety of developmental processes that would be impossible apart from learning. Thus learning is a necessary and universal aspect of the process of developing culturally organized, specifically human, psychological functions. (1978, p. 90) In exploring the difference between learning and development, Vygotsky identified the “zone of proximal development,” defined as “the distance between the actual developmental level as determined through independent problem solving and the level of potential development as determined through problem-solving under adult guidance or in collaboration with more capable peers” (1978, p. 86). The zone of proximal development (“zpd”) captures the dynamism of the process by which the learner moves from dependence or interdependence to independence, through which regulation by another becomes regulation by the self, and the activity that could only be accomplished with another can now be accomplished alone and the function may be considered to be learned, appropriated, or “internalized.” However, the concept of “internalization” is controversial among sociocultural scholars: one critique finds the concept of internalization behavioristic in the sense of a mere copying. Yet the process of internalization may also be seen as beyond simple transmission or copying from one person to another. Rather, the process is a complex and dynamic one, and “while children grow into the life of those around them” (1978, p. 88), the child’s life context and life experience are always different from the adult’s, so that what is taken in or taken up by the child undergoes transformation and is not merely copied. The zpd includes not only other people, but also tools and other artifacts of existence, and the dynamism and infinite variation in life experiences, in this view, preclude any simple transmission or copying. A second critique of “internalization” is that it is mentalistic. Critics who take this view prefer to emphasize the outward aspect of change – what the learner can do. In contrast, to accept the idea of internalization may be to see it as a unification of the material and ideal, the outer reality with a no-less-real subjective reality. School learning is an important source of development. Vygotsky argued that “the only good learning is in advance of development” (1978, p. 89). Because he viewed development, in the sense of transformation of functions, to be the goal of schooling, rather than mere learning of material, Vygotsky was particularly interested in the way that academic (or “scientific”) concepts differ from everyday (or “spontaneous”) concepts (Vygotsky 1978, 1986). Two key differences distinguish the two kinds of concepts. First, academic or scientific concepts are organized in a system of relations, comprising levels of abstraction and principles of order (of vertical and horizontal relations) and generality, whereas everyday concepts are not ordered in a system. Second, academic concepts are deliberately and explicitly taught and connected through instruction with other concepts, whereas everyday concepts tend to be learned simply through exposure in everyday life. To memorize biological taxonomy might show learning, but development is shown by the transformation in thinking when one comes to use the structure and relations of the taxonomic system as a “tool” for taxonomic categorization. Often in school learning, there is interference of everyday concepts in the learning of academic ones, or academic knowledge is learned as inert facts. But in the ideal case, the two forms of knowledge inform each other, with academic concepts reordering the structure of the more concrete everyday knowledge and everyday concepts giving specificity and meaning to the abstract concepts. As suggested above, the academic knowledge provides tools for thinking, as when the periodic table or the taxonomic categories of biology are used as problem-solving devices in the solution of scientific problems. Another controversial issue in sociocultural research is the place of constructivism or social constructivism in the framework. The emphasis in the framework on social interaction, the interpsychological process, and collaborative activity in the zpd, may lead some to see the sociocultural framework as “social constructivist” Socio-Cultural-Historical Research and to favor “guided discovery” kinds of pedagogy. However, many would consider this to be a misreading of epistemological assumptions: pedagogy that relies on learners to discover scientific or academic concepts has the consequence of focusing on the empirical learning associated with spontaneous or everyday concepts, rather than on the theoretical teaching that aims to develop scientific and academic concepts. Academic concepts are organized on abstract principles that cannot be readily “discovered” by learners, even with assistance, but need to be part of a curriculum carefully designed to teach those abstract principles in a way that also forges connections with everyday knowledge of the world. This view recognizes that such concepts cannot be taught directly, but that extensive work is needed to develop curricula and pedagogy effective in theoretical learning and teaching. A growing body of research is devoted to exploring theoretical and empirical teaching and learning in a variety of academic subjects (see Daniels 2007; Kozulin 1996). Sociocultural–historical research has roots in the revolutionary thinking of an earlier time but remains a fertile source of ideas for the current age. It challenges other theories, some time-honored, others new, but shares a commitment to theory and education in the service of human liberation and societal advance. S 3135 John-Steiner, V. (1985).

Socio-Cultural-Historical Research ▶ Sociocultural Research on Learning S 3136 S Socio-economic Status Socio-economic Status This is a composite measure of the social and economic status of an individual’s family of origin. It combines three concepts to measure overall socioeconomic background: (a) educational attainment of the parent(s), (b) family income, and (c) social prestige of the job held by the parent(s). Socio-Economic Status of Family ▶ Family Background and Effects on Learning Socioemotional and Academic Adjustment Among Children with Learning Disorders MICHAL AL-YAGON1, MALKA MARGALIT1,2 1 School of Education, Tel-Aviv University, Tel-Aviv, Israel 2 School of Social Studies, Peres Academic Center, Rechovot, Israel Theoretical Background Learning disorders (LD), as defined above, are one of the most common childhood disorders, occurring in approximately 2–10% of children and adolescents, depending on the nature of the definitions applied (American Psychiatric Association 2000). Most studies investigating children with LD have demonstrated their higher levels of academic challenges and their socioemotional and behavioral difficulties (Al-Yagon 2007; Bryan 1997; Culbertson 1998; Margalit 2010). Following diagnostic evaluation (often including psycho-educational, neurological, and psychiatric components), these children may be eligible for appropriate testing accommodations, specific interventions, and support from the school psycho-educational staff and from external resources. General consensus from large numbers of studies suggests that children with LD exhibit heterogeneous, sometimes overlapping difficulties in three major academic domains – dyslexia, dysgraphia, and dyscalculia – and in the socioemotional domain. These studies also indicated the different cognitive, perceptual, linguistic, and neuropsychological processes that underlie these different domains of LD (American Psychiatric Association 2000; Fletcher et al. 2007). The next sections provide an overview of each of these major domains of difficulty, in terms of their features, underling processing deficits, and major aspects regarding instruction and remediation processes. Academic Adjustment of Children with LD Synonyms Dyscalculia; Dysgraphia; Dyslexia; Learning disabilities Definition As suggested by the DSM-IV-TR (American Psychiatric Association 2000), children with learning disorders manifest an average IQ level and evidence substantially lower achievements on standardized tests (in reading, writing, and/or mathematics) than expected for age, schooling, and level of intelligence. Their learning problems significantly interfere with academic achievement or activities of daily living that require reading, writing, and mathematics skills. If a sensory deficit is present, the learning difficulties must be in excess of those usually associated with the deficit. Learning disorders may persist into adulthood. Research studies examining the academic adjustment of children with LD pinpointed these children’s lower school achievement levels, greater academic performance difficulties, and poorer learning skills compared to children with typical development. The school dropout rate for children and adolescents with LD is reported at nearly 40%, approximately 1.5 times the average (American Psychiatric Association 2000). Findings from follow-up investigations suggest that these academic difficulties persist into adulthood; lower rates of adults with LD attend postsecondary school and lower rates graduate, compared to non-LD adults. Much of the research on academic adjustment in children with LD has focused on dyslexia. These studies highlighted the underlying reading difficulties and the Socioemotional and Academic Adjustment Among Children with Learning Disorders intervention approaches most effective in addressing the central areas of reading deficit (see Toste 2007 for a review). Children with dyslexia manifest a variety of dysfunctional reading performance skills in two major areas: decoding skills and/or comprehension skills (Fletcher et al. 2007; Toste 2007). In examining the decoding problems of children with dyslexia (e.g., slow reading speed, poor reading fluency, and mispronunciation of words in oral reading), studies examined the possible role of deficits in phonological processing and other cognitive processes like working memory deficits, rapid automatized naming deficits, and visualperceptual deficits. Children with poor primary comprehension skills have difficulties in comprehending the content of the material and may also have linguistic deficits involving the semantic processing of written language. Data on these processes underlying reading difficulties have led to diverse intervention studies examining the best practices in reading instruction (see Toste 2007 for a review). For example, recent studies indicated that phonics instruction enhanced reading acquisition among younger as well as older readers. Such research also emphasized that reading instruction and remediation is most effective when highly explicit and intensive, offered in a small and interactive group format, set up in a way that controls task difficulty, and offers instruction in basic elements of reading as well as in metacognitive strategies. Children with dyscalculia manifest a developmental arithmetic disorder in one or more of the basic skills involved in mathematics such as deficits in counting, computational skills, ability to solve word problems, and understanding numbers (e.g., American Psychiatric Association 2000; Fletcher et al. 2007). Research studies suggested several explanations for these difficulties, such as the role of sensorimotor processes in the development of mathematic disorders and the contribution of other cognitive processes such as verbal and nonverbal neurocognitive processes. Such neurocognitive processes may include, for example, verbal-auditory discrimination ability, long-term memory for general information, and visuospatial processes. In exploring the efficacy of mathematical instruction and remediation, researchers have highlighted the importance of diverse techniques. For example, several studies underscored the contribution of teaching the relevant links between different kinds of problems, S mathematical procedures, and real world applications. In addition, studies also emphasized that children with dyscalculia may benefit from the explicit teaching of selfregulation, self-monitoring, and procedural knowledge (i.e., understanding the sequential set of steps required for solving a problem). Such studies also suggested the role of cognitive strategies that incorporate cueing, modeling, verbal rehearsal, and explicit instruction for more effective mathematical instruction. Children with dysgraphia demonstrate difficulties in several major aspects of written expression skills (American Psychiatric Association 2000; Fletcher et al. 2007) such as knowledge of rules for spelling and grammatical usages as well as difficulties in handwriting, completing written assignments, and performing writing compositions (e.g., organization of text and sentence construction). In investigating the possible sources of these written expression disorders, studies have proposed variables such as disordered receptive or expressive language skills and/or neuropsychological processing (e.g., visuospatial, executive-coordination, and dyspraxia – fine motor and graphomotor abilities). Research studies focusing on effective instruction, intervention, and remediation programs for children with dysgraphia lag far behind those focusing on dyslexia and dyscalculia. However, the relatively few available studies did reveal the role of intervention methods such as strategic training, rule-based lexical information, using lexical visual information of whole-word forms, occupational therapy, and using diverse technologies to facilitate intensive repetitive practice. Moreover, beyond this differentiation into three major domains of academic difficulties, some researchers have pinpointed a subgroup of nonverbal learning disorders, which comprise neurocognitive and adaptive deficits manifested in tactile perception, visual perception, psychomotor skills, limited exploratory behaviors, understanding/using the functional dimension of language, and so on. Children with nonverbal LD often demonstrate strong reading and spelling difficulties, weak reading comprehension, and poor arithmetic skills. Socioemotional Adjustment of Children with LD Beyond documenting the effects of LD on academic functioning, research has also indicated these children’s diverse socioemotional difficulties (Al-Yagon 2007; Bryan 1997; Margalit 2010). Data from numerous 3137 S 3138 S Socioemotional and Academic Adjustment Among Children with Learning Disorders studies have underscored that children with LD evidence a wide range of socioemotional difficulties such as poor social competence, poor pragmatic communication abilities, impairment in adaptation to novel situations, peer rejection and loneliness, difficulties establishing and maintaining satisfying social relationships, higher depression and anxiety, more withdrawn behaviors, and a lower prevalence of secure attachment with parents and teachers, all in comparison to typically developing children (e.g., Al-Yagon 2007; Bryan 1997; Margalit 2010). However, it should be noted that not all of the children with LD experience a high level of socioemotional difficulties. Thus, in line with resilience approaches (Margalit 2010), research has also identified subgroups of children with isolated academic problems alongside well-adjusted social and emotional functioning. Examination of the possible explanations for the socioemotional difficulties of children with LD have focused on two major sources: the central processing deficit and the secondary emotional reaction. The first approach has pinpointed the role played by these children’s individual-level characteristics such as internal neurological factors, including information-processing difficulties, impulsivity, and performance and production deficits (Bryan 1997). Such factors have been examined for their effect not only on these children’s academic skills, but also on their perceptions and interpretations of feelings and social situations, which, in turn, may impair their social, emotional, and behavioral skills (Margalit 2010). In contrast, the second approach assumes that these socioemotional difficulties manifested by children with LD comprise secondary emotional reactions related to these children’s primary learning and academic disorders. In this case, their difficulties may be seen as products of these children’s repeated experiences with frustration, academic failures, and high levels of stress. Intervention studies designed to improve the socioemotional and behavioral functioning of children with LD generally include individual/family psychotherapy or social skills training, spanning a wide range of intervention durations, settings, and techniques (Al-Yagon 2007; Margalit 2010). For example, social skills training programs may consist of cognitive behavior modification or metacognition training such as coaching, modeling, role-playing, feedback, and mnemonic strategies to train children in efficient interpersonal problem-solving skills. Recent studies also suggested the possible role of intervention programs focusing on these children’s close relationships with significant others such as parents and teachers (Al-Yagon 2007). Important Scientific Research and Open Questions The study of LD has grown substantially over the last decades, bringing major developments in understanding this disorder’s genetic, neuropsychological, and other etiologies, as well as its features, diagnosis, and intervention approaches. Nevertheless, some important questions regarding academic and socioemotional adjustment of children with LD require additional empirical exploration. First, data from many LD studies demonstrated the high prevalence of comorbid disorders such as attention-deficit/hyperactivity disorder (ADHD), conduct disorder, and major depression disorder (e.g., American Psychiatric Association 2000). For example, the high comorbidity found between LD and ADHD suggests a possible shared etiology. It is beyond the scope of the current discussion to provide a thorough review regarding these groups of children with comorbid disorders; however, these issues must be acknowledged and pursued in future research endeavors. Second, despite growing awareness among educators and clinicians alike regarding the importance of exploring the clinical features and the underlying processing deficits for the socioemotional functioning of children with LD, research studies addressing these difficulties lag far behind those addressing academic difficulties, thus calling for additional exploration. For example, relatively few LD researchers have investigated the extent to which socioemotional and behavioral difficulties extend into adolescence and adulthood, despite growing awareness about the importance of social contexts and close relations with significant others to adjustment throughout life. Furthermore, considering the possible shared etiology for children’s academic and socioemotional disorders, further research should explore the prevalence and types of socioemotional difficulties associated with each of the different major academic LD domains described above. Third, diagnostic evaluation procedures for LD have been widely questioned and criticized; therefore, Socio-emotional Aspects of Learning future research would do well to continue searching for comprehensive criteria and methods such as the use of the response to instruction/intervention (RTI) model, for diagnosing heterogeneous domains of LD.

Socio-emotional Aspects of Learning SANNA JÄRVELÄ Department of Educational Sciences and Teacher Education, University of Oulu, Oulu, Finland Synonyms Emotion; Motivation; Social interaction S 3139 Definition Human thought and action are considered as products of a dynamic interplay among personal, behavioral, and environmental influences. Therefore, the basic assumption involved in the focus on socio-emotional aspects of learning is that learning situations are not purely cognitive situations but are also emotionally and motivationally loaded and situated within a social context. Theoretical Background Learning research has privileged cognitive processes, particularly the information-processing view. Although information processing has generally excluded the consideration of emotion and social relationships in cognition, recent research has confirmed the interaction of cognition and emotion. Also, in the past several decades, research has demonstrated that emotional and social processes are intertwined with their cognitive counterparts and must be considered if one is to understand learning (Leary 2007). In recent years, increased attention has been devoted to the social basis of cognition, taking into consideration how social processes affect learning and performance. A key focus on a socially shared learning approach has been to avoid the dichotomy of the individual versus the group and, instead, to define the ways in which group life depends on individual participation, while individual life depends on the impact of groups (Levine et al. 1993). It has become clear that while trying to understand social learning, we consider an extremely complex set of variables: cognitive, social, emotional, motivational, and contextual variables, interacting with one another in a systemic and dynamic manner. The interrelationships of emotional, social, and cognitive processes form the core of individual competence building. The ▶ affective reactions individuals have in response to positive and negative outcomes in different settings reflect an investment in both attaining and avoiding competence (Elliot and Dweck 2005). Many of the motivational concepts derive from experimental psychology and originally have focused on the self, while the contextual aspects have been in the background. Today, researchers are interested how ▶ motivation is influenced, developed, and constructed within learning contexts. They also focus on reciprocal relationships among individual motivation and peers, learning environment, and culture S 3140 S Sociohistorical Psychology (Järvelä et al. 2010). Conceptualizing motivation in learning contexts builds upon the situated learning paradigm, viewing the process of learning as distributed across the learner and the environment in which knowing occurs, as well as the activity in which the learner is participating. This conceptual framework provides a useful foundation for understanding students’ goals, intentions, and emotions across situations – in real contexts and real time, and the context-person mutual influences have been highlighted. Students’ feelings about learning, the experience of emotions, the level of emotional arousal, classroom structure, and emotional atmosphere within the classroom, all contribute to their motivation to learn (Meyer and Turner 2002). Many researchers have tended to discuss emotions as intrapsychological phenomena. They are defined as subjective experiences having a positive or negative quality. Yet, an argument can be made that emotions are social phenomena involving social experiences. For example, love and sadness can be considered social rather than personal emotions, with their antecedent or indicators found at the social level, outside of a particular person. Other emotions also arise in social contexts and, as regulators of behavior, have social consequences (Weiner 2007). In sum, individual emotions and motivation are formed at the interface of personal, contextual, and social aspects. Finally, in successful learning, emotions and motivation are essential aspects of constructive self-regulated learning. Important Scientific Research and Open Questions The development of socio-emotional strengths will become increasingly important in a rapidly changing society, which demands coping with multiple challenges, stressful situations, and competing goals. Therefore, understanding increasingly dynamic social learning environments will challenge the research field in terms of conceptual and methodological development. Methodological development has advanced the research field. Researchers in process-oriented qualitative studies have targeted more intense and fine-grained relations of emotions and other aspects of learning process (Meyer and Turner 2002) in a variety of learning contexts, ranging from classroom interaction studies to technology-enhanced learning contexts (Järvelä et al. 2010). To conclude, research on socio-emotional aspects of learning has taken new avenues in conceptual and methodological development in order to grasp the dynamics of motivation and emotions in multiple contexts and, thus, move closer to actual practices. There are, however, still challenges regarding conceptual clarity and the generation of rigorous empirical designs in field research to study motivation and emotions across contexts and over time.

The approach focuses on socio-technical learning communities within higher education. The word socio-technical interrelates to technical systems as well as social structures – human communication and learning is integrated into a technical platform. A special case of socio-technical learning is experimental online learning. Theoretical Background Learning Paradigm Socio-technical learning follows the constructivism approach. It means learning processes are cognitive constructed and socially framed. Learning is defined as a proactive process of constructing rather than acquiring knowledge. Individuals create sense of their own world. Everything they come in contact with is S 3141 constructed by their own models of their experience. Hence, learning is not defined as simply the transmission of data from one individual to another, but a social process whereby knowledge is co-constructed in a situation within a community of practice (cf. Lave and Wenger 1991). Teaching or instructions have the task to support and scaffold (giving structures) this construction rather than communicating knowledge. Current discussions in higher education focus on shifting the focus from the teacher’s teaching to the student’s learning. Promoting concepts for the shift from teacher-centered teaching to student-centered learning concepts are not new; however, discussions about pedagogical learning approaches got a new drive as new community platforms based on Web 2.0 technologies emerged, for instance, platforms for usergenerated content like wikis, blogs, and social networking platforms like Facebook or Myspace (Jahnke 2009). The socio-technical approach has the claim to support teaching and learning differently. It says that a new balance between teaching and learning is essential for supporting creativity and best learning effects. Learning-centered approaches promote a re-orchestration of teaching and learning – information-generating, pushing-and-pulling arrangements for learners – where learning is regarded from the viewpoint of the learners. Exploratory and Research-Based Learning: Foundation for Socio-technical Learning Exploratory learning is an active process in which a learner constructs his own meaning based on his own experience. This means learners explore something (e.g., artifacts, hypotheses, ideas, and results) without having or giving a solution by the teachers. Learners “interact with the world by exploring and manipulating objects, wrestling with questions and controversies, or performing experiments” (Bruner 1961). However, exploratory learning does not mean unguided learning (Kirschner et al. 2006). Exploratory learning concepts (also known as discovery learning) encourage the learner to do experiments and to uncover relationships. Learners get the opportunity to discover unknown and unexpected object properties, characteristics, and theoretical models by following various learning paths. Exploratory learning often follows Kolb’s “experiential learning theory” (Kolb and Boyatzis 2000) covering four steps: concrete S 3142 S Socio-technical Learning experiences (being involved in a situation, doing something), active experimenting (testing a theory by making a plan and following it), reflective observing (looking at an experience and thinking about it), and abstract concept-making (forming theories about why an experience happened the way it did). A pedagogical approach which includes appropriate structures for the teaching and learning process is called research-based learning (Jenkins et al. 2003) where students undertake research and inquiry. Teaching and learning is structured by the process of research phases (building hypothesis, delivering theoretical framework, making research design, doing inquiry, describing results, making conclusion). A special case of socio-technical learning is experimental learning. It is defined as combined forms of research-based and experiential learning that take place within remote laboratories using an online learning platform with an Internet-based access. Socio-technical Learning in the Age of Web 2.0 In a former typical one-room schoolhouse 100 years ago, “learning was social, not didactic,” writes John Seely Brown. To foster learning as social process, one approach focuses on learning communities of practices. In words with Digital Natives, TechnologyEnhanced Learning support social learning by using new media like Social Networking, Forums, or Blogs. Such Web 2.0 platforms offer new possibilities to easily enable social learning in groups (e.g., Jahnke and Koch 2009). The availability of web access from anywhere at any time has made it easier to engage students in learning communities and can also link weakly coupled learners. In the Web 2.0 age, some academic staff developers stress that socio-technical learning scenarios in higher education need more attractive concepts (Collins and Halverson 2009), for example, concepts that supports problem-solving without having any standard solutions by using Web 2.0 platforms or socio-technical learning communities. Socio-technical Learning Communities Socio-technical learning communities are forms of communities of practice – introduced by Lave and Wenger (1991) as well as Wenger et al. (2002). They are generated through social relationships among individuals “who share a concern, a set of problems, or a passion about a topic, and who deepen their knowledge and expertise in this area by interacting on an ongoing basis” (Wenger et al. 2002, p. 4). With Preece (2000), socio-technical communities differ in the following four areas: ● Group size (e.g., in research on communities, groups with 25 members are considered small, whereas groups with 1,700 are considered very large) ● Primary content (e.g., discussion boards about Harry Potter books and movies, discussions about sports like marathon training, communication about stock exchanges, and information sharing about lectures at a university) ● Life span (e.g., several years or just for one topic) ● Presence (e.g., either pure online communication, face-to-face, or mixed communication) For the design of socio-technical learning, the analysis of the appropriate interplay between social and technical parts is needed. On the one hand, sociotechnical learning communities consist of actors who use technical systems to communicate and share knowledge. On the other hand, the technical system influences the interaction between community members (human–computer interaction). Social Structures for Learning In contrast to work groups in companies where the group members are formally bound, socio-technical communities consist of more informal than formal connections between members. Formal structures are characterized by conventional forms of behavior, and established conventions, for example, behavior which is formally bound by a work contract, or a formal role represented by a job/task description (e.g., formal moderator). Informal structures are rather casual, unofficial, loose, and not triggered by any rules (e.g., activities of informal moderation). Social structures are patterns or interrelationships of social elements (e.g., human behavior and relationships within socio-technical communities) that can be called “roles.” To observe the shape of roles in an online community, observable categories are Socio-Technical Learning Communities S needed. According to Jahnke’s role model (2009), four categories are useful for analyzing and designing sociotechnical learning processes: Humanities, Social Sciences) look like? How can we measure the success, effect, and impact of sociotechnical learning models? (a) Learner’s position within the community; relations to other members. Questions for designing sociotechnical learning processes are how to bring the learners from outside to the middle of the core members and what methods are helpful for teachers to support this process. (b) Learner’s tasks/activities within the learning process. Questions for designing socio-technical learning processes are how to support different activities. (c) Tacit, implicit, and explicit expectations of learners. Questions for designing socio-technical learning are how to support conflicting expectations or problems of learners within the researchbased learning process. (d) Interactions/role-playing (e.g., problem that students do not regarded themselves as researchers). Questions for designing socio-technical learning are how to give a structure for learners by having enough room for move, how to support rolechanging, and what methods are useful. Cross-References Important Scientific Research and Open Questions Based on mentioned theoretical background, a sociotechnical learning model has the following dimensions: ● Social design for socio-technical learning (e.g., com- munication, different social modes, cooperation) ● Technical design (e.g., Web 2.0, technical platforms, usability) ● Pedagogical design (e.g., model which guided exploratory, research-mode learning) and an appropriate interplay of all three dimensions. The guided questions for designing are: what socio-technical design for research-based learning is needed? Derived questions are: what is an appropriate balance between teaching objects and learning activities in socio-technical environments, how to make learner-centered learning, or in other words, what is an attractive learning model from the student’s perspective?

Socio-Technical Learning Communities ▶ Socio-technical Learning S 3144 S Socio-technological Change of Learning Conditions Socio-technological Change of Learning Conditions INES LANGEMEYER InterMedia, Faculty of Education, University of Oslo, OSLO, Norway Synonyms Changed conditions for learning Definition The idea of investigating socio-technological changes of learning conditions was enunciated by historicalmaterialist approaches to learning such as the Cultural-historical School (Vygotsky, A. N. Leont’ev, Luria and others, originated in the 1920s) and the Berlin school of Critical Psychology (Holzkamp, Osterkamp, Schurig, F. Haug and others, established in the 1970s). This idea was nurtured by a particular Hegelian or Marxian notion of learning defined as productive human activity by which not only cognitive schemas, behavior, and personality develop but also the human potential (Gattungswesen) at a certain culturalhistorical level. From this angle, learning is seen as a dimension of the entire sociocultural development in which technological innovations play an important role. Rather than in terms of their impact on learning, socio-technological changes are explored as conditions and demands to which humans actively and creatively respond. Furthermore, these changes are recognized as largely connected to the drive of capitalist relations to increase productivity, to rationalize the mode and the relations of production, and to augment the capitalist control of the production forces. Therefore, these changes are not interpreted as a linear progress to higher levels of societal life, but studied as contradictory developments under which learning is realized or under which people are expected to learn. Theoretical Background Conceptualizing the socio-technological change of learning conditions requires the reciprocal interpretation of the following three dimensions: (1) the sociotechnological change, (2) the significance of societal conditions for learning, as well as (3) their change as driven by a socio-technological one. Historical-materialist approaches engage with these three dimensions by analyzing the shifts of the mode of production, the changing division of labor, and the alternation of the theory–praxis relation which is dominant at a certain period of time. This three-dimensional perspective is uncommon to many theories of learning and analyses of sociotechnological change. While learning is often conceptualized in mentalist terms regardless of its material societal conditions, socio-technological change is largely identified with either the gradual substitution of manpower by technology and thus suspected of diminishing the scope of human development; or it is interpreted as a new kind of man–machine interaction to which the labor force simply needs to adjust. Only the use of computer and Internet technologies as “tools” for information processing and knowledge production inspired researchers of other theoretical traditions to think of these advancements more in terms of a new societal potential for learning activities. The advantage of historical-materialist approaches to learning and socio-technological change lies in their capacity to connect those three dimensions, and thereby seek to overcome individualist and mentalist notions of learning as well as any reductionist technological determinism. The dialectical conception of human praxis or “activity” is a key to this. In general, technologies – including tools – are conceived of as social forms of action rather than isolated material objects. Furthermore, historical-materialist approaches conceptualize learning as a specific kind of “object-related activity” by which humans individually or collectively gain control of their societal living conditions and life’s material production (Holzkamp 1993; Stetsenko 2005). In so doing, these approaches do not outplay the objective against the subjective side of learning. Not only is “individual skill and knowledgeability” addressed as a “currency of activity” (Sawchuk 2006, p. 608), also the self is seen – within “a unique constellation of activities in the real world” – as a “person’s ‘leading activity’” (Stetsenko and Arievitch 2004, p. 477). The fact, for example, that humans are making tools for satisfying human needs is seen as the germ cell of theoretical and experimental knowledge which is to encounter even in natural religions and which forms the basis of modern natural sciences. This is illuminated by the following explanation: Hence humans would start making tools no longer spontaneously but on purpose and collaboratively, this tool production Socio-technological Change of Learning Conditions would presuppose generalized knowledge of human needs, theoretical insights of using certain tools in a specific environment and of their impact on certain material objects. By actively transforming the environment and by deliberately “building” more and more invariant characteristics into it (which are already cognized), humans would create the material basis for experimenting with unknown aspects of nature (Holzkamp 1973, p. 126). Consequently, not only the scope of epistemic progress of one generation also processes of individual learning and personality development would depend on the cultural-historical level of life’s material production. Against economic reductionism, sociotechnological changes are not identified with technological developments only. Shifts in the division of labor and, correspondingly, alternations of the theory–praxis relation (cf. PAQ 1987) are considered as well. Among numerous socio-technological changes, historical-materialist approaches regard the one related to automation-, information-, and communicationtechnologies as paramount, because it superseded the radical division of intellectual and physical labor which largely determined – until the 1970s – the prevailing mode of rationalization. Important Scientific Research and Open Questions The derogating effects of industrialization on learning and human development can be studied in relation to Frederick W. Taylor’s Principles of Scientific Management (1911) in an exemplary way. These principles corresponded to the paradigm of mechanizing technologies such as the assembly line which – combined with the great machinery – successfully facilitated mass production. Simultaneously, these socio-technological conditions created a mass of unskilled workers on the one hand and a small, techno-scientific elite of engineers and managers on the other. In so doing, they represented a point of culmination for the radical division of manual and intellectual labor. Facing this “progressive division of labor,” Vygotsky (1930/1994, pp. 176, 181) echoed Marx’s critique that “every new level in the development of the production forces of the society has not just failed to raise humanity as a whole and each individual human personality to a higher level, but has led to an ever deeper degradation of the human personality and its growth potential.” S Therefore, he emphasized the necessity “to overcome the division between physical and intellectual work and to reunite thinking and work which have been torn asunder during the process of capitalist development.” Vygotsky hoped for mitigation by poly-technical education, but could not foresee any socio-technological change which portended an end of the de-intellectualization of manual labor and the saturation of science and intellectual work with partial political and private economic interests. In the 1970s and 1980s, critical psychologists and sociologists launched a research project (“Projekt Automation und Qualifikation”) and scrutinized the shifts of the mode of production at numerous sites of automated production plants (PAQ 1987). Due to the fact that manual and routinized labor was increasingly replaced by automation technologies and that new work activities emerged in the area of research and development (cf. Bell 1973), programming, controlling, improving, optimizing, and inventing collaborative uses of these technologies, the research group concluded that labor would undergo an intellectualization and be subjected to a new type of scientification (Verwissenschaftlichung). This development would break with the Taylorist domination of science/theory over praxis since steps of planning, inventing, executing, and controlling would now merge into integral work tasks. Neither the active involvement of humans in this new labor process could now be completely standardized, nor could workers be entirely controlled by a hierarchical division of labor. Instead, the intellectual and collaborative capacity of problem solving and inventing would come to the fore. The research group PAQ therefore did no longer identify “scientification” with the scientific constructing of production technologies and the standardization of work knowledge and work routines only. It rather emphasized the challenge to cope with information which is presented and processed in a scientific manner. It stressed the requirements of analyzing errors and solving problems that occur in automated production and work processes. Thus, the theory–praxis relation would be subjected to a radical change: Large parts of the relevant knowledge for labor and production would emerge along with activities of experimenting, analyzing, and learning during the work process. Since science/theory could no longer be separated from, and would no longer “reign” over praxis, the former division of labor 3145 S 3146 S Socio-technological Change of Learning Conditions would have become obsolete. A glance of hope for humanizing work and for democratizing the relations of production appeared. However, a new arena for conflict and contradiction has come forward with respect to the issue of learning (cf. Langemeyer 2005; Sawchuk 2006). According to the needs of scientificated labor, Langemeyer and Ohm (2009) see collaborative and experimental forms of learning emerging which are facilitated by (mobile) communication-, controlling-, visualizing-, and simulation-technologies as well as “intelligent” software agents and other computational artifacts. However, since learning has become an integral part of intellectualized work activities, such technological devices are also invented to reassure the capitalist control over labor, production, and productivity. This is achieved for example by new technologies of (self-) surveillance. Another issue is the digital form of information goods, or more precisely, their unlimited duplicability. Since software, e-books, e-journals, etc., are often made for commercial purpose intellectual property rights, copy protection and other barriers are created to ensure that these products are purchasable. Such innovations have however quite contradictory effects with regard to the new scientification of labor. Different from open software, commercial software entails an inaccessible programming code and therefore is made unusable (or very partially usuable), for instance, for programmers’ learning and experimenting activities. Further difficulties arise with the augmenting complexity of computational systems, the new relations of production, and the emerging global division of labor. Since most of the computing systems used in the beginning of the second millennium can no longer be (re-) produced and comprehended by an individual person only, the scope of learning activities necessarily becomes fragmentary and essentially dependent on better and more sustainable forms of cooperation and organization. Globalized labor markets reinforce competitive relations, and the global division of labor fosters not just internationally but also regionally a new segregation between a skilled and an unskilled workforce. These socio-technological changes are not simply creating or enhancing conditions of learning. They simultaneously demand and limit, restrain or impair learning at work. Thus, the question arises how professionals cope with scientificated labor. This issue also leads to query other relevant societal conditions such as education (system), work culture and social class (cf. Sawchuk 2003), work contracts, gender relations, social welfare, or globalization (cf. Livingstone et al. 2008) which influence the dynamics of a new scientification of labor and its challenges of learning.

Socratic Questioning involves the use of systematic questioning, inductive reasoning, universal definitions, and a disavowal of knowledge (Carey and Mullan 2004). Socratic S 3148 S Socratic Questioning Questioning refers to a procedure in which people attempt to change others’ minds, as well as a process that allows people to change their own minds (Carey and Mullan 2004). Socratic Questioning is defined as “the dialectical method supposedly employed by the historical Socrates, and displayed in Plato’s earlier dialogues. . . the teacher should by patient questioning bring the pupil to recognize some true conclusion, without the teacher’s telling the pupil that that conclusion is true” (Carey and Mullan 2004, p. 221). Socratic Questioning is used as a teaching method to facilitate the process of learning through probing student thinking and reasoning in complex problems, and structuring a problem-solving process (Rhee 2007). Socratic Questioning is a form of active learning pedagogy that allows the learner to develop higher order thinking skills such as analysis, synthesis, and evaluation. Theoretical Background Socratic Questioning comes from the teaching style of Socrates (469–399 BC) who was a Greek philosopher and one of the founders of Western Philosophy. Socratic Questioning introduces a problem and directs the conversation back to key points to allow students discover the answers of the problem and the content while avoiding lecturing. Ellerman et al. (2001) state that Socratic Questioning or Socratic Method engages students in interacting with the teacher and other students: " The classical archetype for the teacher in the active learning model was Socrates. Socrates could not “transmit” knowledge as from teacher to student because he had what is now known as “Socratic ignorance”. Instead of “disseminating knowledge”, Socrates would engage his interlocutors in a dialogue about the topic at hand. He would ask pointed questions to show the shortcomings in the conventional wisdom and thus he would try to catalyze his dialogical partners into thinking for themselves to take an active role in thinking through a question or problem rather than just reciting the orthodox views poured into people by the ambient society and its formative institutions. Socrates also helped demonstrate the fallacy of assuming that people want to learn. Thus the Athenian citizens whom Socrates pursued with his questions eventually had him put to death for his troubles. Plato had more success in communicating Socrates’ thinking than Socrates himself, by using a combination of narrative and abstract modes of communication in his dialogues. (Ellerman et al. 2001, pp. 171–172) The Socratic method uses a carefully constructed series of leading questions to draw information out of learners, rather than providing learners with the information or answers of problems. This one-on-one engagement leads learners to arrive at logical responses and to the point where knowledge, application, synthesis, and evaluation are integrated as a form of active learning pedagogy (Rhee 2007). Neenan (2009) states that Socratic Questioning is a cornerstone of cognitive behavioral coaching for guided discovery and cognitive behavior therapy that highlights how changing a person’s thinking leads to emotional and behavioral change. Socratic Questioning raises awareness, promotes reflection, and improves problem-solving thinking (Neenan 2009). According to Neenan (2009), the characteristics of good Socratic questions are being concise, clear, open, purposeful, constructive, focused, tentative, and natural. By considering coach–coachee dialogues, the characteristics of good Socratic questions are defined by Neenan (2009) as follows: ● Concise – keeping the focus on the coachee ● Clear – reducing potential coachee confusion or misunderstanding by avoiding prolixity or jargon ● Open – inviting participation and exploring ideas ● Purposeful – explain the reasons for the questions ● ● ● ● [that coach is] asked Constructive – promoting insight and action Focused – on the coachee’s current concerns Tentative – not assuming the coachee can answer [the coach’s] question Neutral – not signaling the answer which would indicate your viewpoint (Neenan 2009, p. 252) Neenan (2009) emphasizes that “asking good Socratic questions is an essential skill for all coaches to encourage coachees to reflect on their thinking and actions in order to develop new problem-solving perspectives, improve performance, achieve goals and take their lives in often unanticipated directions” (p. 263). Beside the importance of the asking good questions, teaching a skill, giving feedback, clarifying points, pointing out perceived inconsistencies in the person’s thinking, offering advice, and making suggestions are Socratic Questioning S offered by Neenan (2009) as important techniques for a successful practice of the Socratic Questioning. ● Keeping participants actively engaged in the Important Scientific Research and Open Questions Rhee (2007) emphasizes that Socratic Questioning is traditionally perceived as a teaching tool but it is also a concrete analytic tool for the student. Rhee (2007) states that the root of Socratic Questioning/Method is grounded in philosophical inquiry followed by many law teachers and also adapted to a scientific framework for solving problems: Paul and Elder (2007) focus on the forms of Socratic Questioning that can be used in analyzing reasoning: “the purpose of the reasoning, the questions being asked, the information being used, the beliefs being taken for granted or assumed, the points of view embedded in the reasoning, the concepts guiding the reasoning, the inferences being made, and the implications of the reasoning” (p. 32). In addition, Paul and Elder (2008) state that there are universal intellectual standards used for thinking by educated and reasonable persons. The universal intellectual standards “include, but are not limited to, clarity, precision, accuracy, relevance, depth, breadth, logicalness, and fairness” (Paul and Elder 2008, p. 32). According to Paul and Elder (2008), skilled thinkers explicitly use intellectual standards on a daily basis without being aware of these standards. Paul and Elder (2008) distinguish three general categories of Socratic Questioning: spontaneous, exploratory, and focused. Paul and Elder (2008) state that all three questioning categories can cultivate student thinking: " All three types of Socratic discussion we have discussed require instructors to become more skilled over time in of the art of questioning. They require the instructor to develop familiarity with a wide variety of intellectual moves. The cultivation of critical thinking can be enhanced by adapting spontaneous or unplanned, exploratory, and focused modes of orientation and applying the formal mechanics of Socratic Questioning within each mode. (Paul and Elder 2008, p. 35) Paul and Elder (2007) suggest that students can use Socratic Questioning in group discussions. The benefits of using Socratic Questioning are summarized in four categories (Paul and Elder 2007): ● Keeping participants focused on the elements of thought ● Keeping participants focused on systems for thought ● Keeping participants focused on standards for thought 3149 discussion " Many years ago, the mathematician George Polya showed generations of math teachers and students that problem-solving can be learned through the heuristic of simple questions that stimulate curiosity and creativity. There is a connection between the Socratic Method and techniques of mathematical problemsolving. The Socratic Method facilitates this process of learning. Classes can have the feel of a dialogue: the right questions, level of student participation, challenges, and disagreements among students and professor. At times, however, the method becomes stale or mechanical; an air of routinization can set in. But sometimes the dialogue seems to lack a grander design. It is easy to see how a repeated diet of the Socratic Method can lead to a feeling of a monochromatic routine. (Rhee 2007, p. 884) According to Rhee (2007), students, who often fail to connect the abstract concepts with the real-life uses, may face to follow the mechanical, repetitive, and routine tasks of the Socratic Questioning. Therefore, the Socratic Questioning should be complemented with the techniques of problem-solving.

Definition REM: rapid eye moment sleep NREM: non-REM sleep Wiener entropy: Wiener entropy describes the distribution of power in a sound. Much like Shannon entropy, which indicates the degree of randomness in a probability distribution, a low value of entropy indicates a highly ordered distribution. In the case of Wiener entropy, a low value of entropy represents a signal in which a majority of the power resides in a subset of the frequencies available. Quantitatively, Wiener entropy R exp log Sðf Þ R Sðf Þ is the ratio of the geometric mean to the arithmetic mean of the power spectrum, and ranges from 0 (low entropy, high order) to 1 (high entropy, low order). Sometimes, the log of the ratio is the quantity used, in which case the value ranges from 0 to negative infinity, with values of larger magnitude (i.e., less negative) indicating more order. Variance of Wiener entropy (entropy variance): This  2 refers to the statistical variance (i.e., E ð x  xÞ ) of the Wiener entropy calculated over a discrete song segment. It is always a positive value. Since Wiener entropy reflects the distribution in the power spectrum, higher variance of entropy implies a more rapidly changing power distribution, hence a more complex sound. In the songs of developing juvenile birds, low Wiener variance songs are those that have less structure. Song Learning and Sleep Theoretical Background Sleep is a behavior broadly distributed in the animal kingdom. Definitions of sleep include three criteria: specific postures, increased sensory thresholds, and specific electrophysiological properties. There is no universally accepted definition of sleep hence its phylogenetic distribution is unresolved, but it is broadly observed in vertebrates and there are well-defined sleep-like states observed in worms and flies. There is also no single function that sleep serves, nor are the functions of sleep and the adaptive advantages of sleep limited to the brain. In birds and mammals, however, there is compelling evidence in some species that sleep contributes to learning. In humans, investigations of the role of sleep in learning have examined memory consolidation, the process whereby a newly formed memory trace is transformed from a labile state, where it is susceptible to interference or decay, into a more stabile memory. In a typical form of the experiment, groups of subjects learn a task, and a given group’s performance is then tested at one or more periods in the following days. A common pattern of results is that performance improves immediately after training, drops throughout the first day, has returned to levels achieved immediately after training on the following morning, and is stable thereafter (hence the memory is “consolidated”). This pattern has been observed in simple perceptual and motor learning tasks, generalized speech perceptual learning, and sensorimotor learning. A similar pattern of sleep-related learning has been observed for birds on a simple perceptual learning task. Sleep has also been implicated in facilitating insightful learning, and other higher level cognitive tasks. Critical questions are why initial memories are labile, how daytime experience degrades performance, and how sleep stabilizes memories and creates new information. There are two common theoretical treatments of how sleep interacts with neuronal plasticity. One emphasizes homeostatic mechanisms to regulate overall neural excitability (Tononi and Cirelli 2006) and the other emphasizes coordinated reactivation (of brain regions) or replay (of single and populations of neurons) to transfer information across brain regions and stabilize memories (Diekelmann and Born 2010). These concepts are not mutually exclusive. There are only a few animal model systems that have been developed to study sleep and learning S phenomena, one of which is birdsong learning. The oscine birds (or “true” songbirds) are a suborder of passerine birds comprising some 4,000 species. Notable within oscine birds is the tremendous variability in the structure of songs at all levels of analysis, both across species and across individuals within species. Song is also used in a very broad range of behaviors. One central feature of song, perhaps shared universally across oscine birds, is that song is learned. It has been thought that song learning was restricted to oscine birds and not to all passerine birds, but recent results point to the possibility that some aspects of songs (such a temporal patterning in duetting species) might also be learned in neotropical “suboscine” species. This is a group of approximately 1,500 species for which little research has been conducted. Another distinction between oscine birds and other avian species may be in sleep structure. Most bird species have little REM and do not show a clear pattern of nocturnal variation in NREM and REM. In the intensively studied zebra finches (Taeniopygia guttata), however, a surprisingly mammalian-like pattern of sleep structure has been observed, with clear episodes of slow wave sleep within NREM, decreasing NREM and increasing REM throughout the night, and long and frequent REM near the onset of the diurnal period. This revives questions about the evolution of sleep, given these complex sets of traits are shared by mammals and apparently oscine birds in general, but are separated by other bird taxa and reptiles that seemingly lack these traits. In the typical song learning pattern, early in development juvenile songbirds acquire a sensory model of song from exposure during a critical period to one or more adult male “tutors” (in most species song is sexually dimorphic), and this exposure triggers a second, sensorimotor stage when birds slowly learn to imitate the memorized song. Access to the tutor song (assessed by isolate rearing) and access to auditory feedback during practice singing (assessed by deafening prior to subsong or rearing in high noise levels) are both essential for normal song development. A central hypothesis has been that the song memory is stored as an “acquired sensory template” that is then used to evaluate auditory feedback during singing (Konishi 2004). In the absence of tutoring, a less precise “innate template” is used in the evaluative process. The “template” concept could be implemented by direct real- 3151 S 3152 S Song Learning and Sleep time comparison of auditory feedback with sensory memory, and as well – as recent data suggest – by offline activity especially during sleep. The innate and acquired templates remain hypothesized constructs whose anatomical localization and functional organization are not known, but recent observations (below) implicate particular pathways in giving rise to auditory input to the song control circuitry. Sensorimotor song learning typically progresses through three developmental stages. Subsong is characterized by low amplitude vocalizations of highly variable duration and low repeatability. Following subsong, juvenile songbirds enter a “plastic” song stage consisting of distinct, repeatable segments of song, delivered at a higher amplitude than subsong. As individual syllables emerge during plastic song, their order and morphology may change. Lastly, at sexual maturity, the plastic song crystallizes into an adult song, with the degree of plasticity in the pattern and morphology of syllables throughout the rest of life dependent on species, age, season, social interactions, and other factors. In zebra finches, common laboratory birds, the subsong, plastic, and adult song stages begin at roughly 25, 40, and 90 days respectively after hatching. Important Scientific Research and Open Questions Recent work has investigated how controlling the introduction of the tutor song during development influences song learning (Derégnaucourt et al. 2005). When a juvenile zebra finch raised in isolation of adult song finally gains access to a tutor song, a change in spectral features of song can be observed. In particular, the variance of the Wiener entropy, a measure of spectral complexity, gradually increases from the day following the introduction of the tutor song and continues to the onset of adulthood, at which point the song crystallizes. Over the course of a day, a shorter time scale pattern in the entropy variance also manifests. Entropy variance starts at a lower value each morning than the previous (or following) day’s peak. Although this nightly effect of sleep appears to be in opposition to the more long term ontogenetic song learning process, it is adaptive: larger fluctuations across sleep correlate with greater efficacy in song copying. The daily changes observed in entropy variance appeared to be a direct result of sleep rather than spontaneous degradation due to lack of practice or a function of the time of day. Birds prevented from singing in the afternoon even for long intervals did not exhibit degradation, and birds not permitted to sing in the morning sang degraded songs when starting to sing in the afternoon. When sleep was drug induced for 2–3 h during the day, upon awakening in the afternoon the first songs were degraded. These results demonstrate a causal relationship between sleep and variation in singing behavior (degradation followed by improvement), as measured by entropy variance. Not only has song learning behavior been well studied in zebra finches, but substantial physiological data has been collected on the underlying neural control of these behaviors, both in adults and juveniles. Song production is driven by activity in two telencephalic pathways that converge at the robustus nucleus of the arcopallium (RA), the primary forebrain output nucleus of the song system. Nucleus RA, analogous to motor cortex, directly innervates the brainstem nuclei controlling the syrinx, the avian vocal organ, as well as brainstem respiratory nuclei, to coordinate respiration and singing. RA also projects to other cortical structures and to thalamus. The neural activity patterns in this and other song system nuclei show state-dependent changes. For example, in sleeping adult zebra finches, neurons in RA spontaneously discharge individual or sequences of bursts that closely mimic the patterns those neurons show when the birds sing (Dave and Margoliash 2000). This “replay” phenomenon has been hypothesized to be tied to plastic mechanisms for maintaining adult song, which remains an open question. Many burst patterns of individual RA neurons change over sleep, and it is thought that these changes have to be coordinated else the adult song would rapidly degrade. In juvenile birds at the plastic song stage, there is strong evidence for physiological changes accompanying the daily fluctuations in singing (Shank and Margoliash 2009). Spontaneous neural activity in sleeping juvenile birds in nucleus RA prior to the introduction of a tutor song exhibits predominantly tonic firing. On the night immediately following the introduction of a tutor song, bursting activity substantially increases. Bursting continues to increase on subsequent nights. This physiological change leads the change observed in song production behavior, which is Sparse Feature Learning observed the following day. Still, it is not known which specific nuclei in the song system or auditory system pathways are important for driving these processes, and a causal relation between sleep dependent learning and nighttime bursting remains to be fully established. This spontaneous bursting activity also exhibits a clear sensory character. Distributions of intervals between spontaneous spiking events in RA from birds with the same tutor song exhibit greater similarity than across groups. This strongly implies that acoustic features of the tutor song influence the spontaneous activity of nucleus RA shortly following the introduction of tutor song. How auditory memories are transferred to the motor pathway remains to be elucidated. The functional role of the degradation in syllable morphology across sleep is still unexplained. One hypothesis is that the degradation and subsequent readjustment pushes the song production system through a greater range of motor behavior and resultant sensory feedback. This would be consistent with general studies in learning theory, which imply more efficacious learning with a greater sampling of the decision space.

Neurodynamics is an interdisciplinary area that included examination of neural oscillations involved in neural fields. Characteristics of neural field activity are linked to cognitive functions, for example, perception, action, and learning. Neuro-semiotics is a term first coined in the late 1970s, which initially referred to the study of sign in the context of neurological process and dysfunction. It has evolved as a wider sub-domain of biosemiotics (from the Greek “bios” meaning “life” and “semeion” meaning “sign”), including cognitive neuroscience. Within SCA, the concept of sign develops beyond traditional concepts of code. The term “noema” comes from the Greek “nόZsiς” (noesis) to designate correlated elements of structure of any intentional act. Advances from such diverse knowledge domains as Field Theory (from physics and refers to the mathematical properties of physical phenomena) and biosemiotics are beginning to converge and significantly influence how we now think about the science of intentionality. Our ability to understand ourselves and others in space and time is fundamental to the evolution of our learning and cognition. Theoretical Background The SCA model explores how we can develop a deeper understanding of human intentionality in terms of child spatial cognition embodied in their actions. It takes a biological systems approach that is informed by neurodynamics and neuro-semiotics. Two principal questions underpin the model: ● What can gesture reveal about neuro-atypical and Synonyms Deed; Involving; Relating to Definition Spatial Cognition in Action (SCA) is concerned with the corporeal, neurodynamics, and neuro-semiotics of human capacity to perceive, simulate, synthesize, and execute knowledge (noesis) of action of “self ” and with “other” (i.e., other person or artifact) in veridical, imaginary, and hybrid space. Corporeal relates to embodiment and comes from the Latin “corporeus,” from “corpus” meaning “body.” The nature of such action can be explored through gesture; where gesture is considered an intentional action expressed either corporeal neuro-typical child spatial cognition? ● Is there the potential to influence gestural capacity in children? Roy (1996) considered human action as a “complex non-linear dynamic system” having both fixed (steady states) where some are “attractive,” that is, neighboring states that tend to converge toward the fixed points termed “attractors.” Unpredictable behavior patterns may be termed “chaotic”; thus, such systems allow for behavior to be emergent. Affordance (environmentally or internally driven) provides one means of reducing the system complexity. Dynamic System Theory (DST) and neural network architecture (ANN) were successfully applied, establishing the “proof of concept” for the Spatial Cognition in Action (SCA) computer recognition of dynamic cerebral palsy gesture (1994). Intentionality of action has a long history philosophically (e.g., Aristotle; Aquinas 1272; Husserl 1800s; Merleau-Ponty 1963/1964), in performance (e.g., Adams 1891; Bacon 1881; Decroux 1961), in the domains of child motor development (e.g., Kelso 1987; Thelen et al. 1994), and in the neuroscience of action and motor control (including Bernstein 1967; Keslo 1984; Fuster 1997/2007; Rizzolatti et al. 2001; Rizzolatti and Arbib 1998; Jeannerod 1994 cited in Panayi 2010). In the last two decades researchers have successfully applied a range of mathematical modeling techniques to the dynamic and learning aspects of intentionality. Advances in both vision research and computing power have made it possible to both recognize aspects of human action and to create believable synthetics characters (avatars) and autonomous agents (robots). Such technologies are now being used to enhance a diverse range of human activity, for example, learning, medicine, rehabilitation, and leisure. The SCA Model considers not only the dynamics, driven by environmental stimuli and affordance but also the significance of relevance and salience based on the “experiences” of the organism (child) (Panayi et al. 2005). Field Theories are being applied to Perception, Action, and Cognition (PAC), for example, Dynamic Field Theory (DFT) to simulate child cognition (Spencer and Schöner 2006), Child Spatial Cognition in Action (Panayi et al. in preparation), and Dynamic Systems Theory is being revisited in the context of neo-Piagetian learning (Rose and Fischer 2009). Similarly, Quantum Field Theory (QFT) is being applied to the modeling of the neurodynamics (e.g., Freeman and Vitiello 2007). Likewise, researchers in the field of neuro-semiosis (e.g., Bouissac 2006; Hoffmeyer 2007; Barbieri 2010; and others) offer a means of bringing together the neurology and salience of action. SCA deals with cross-domain phenomena that are multi-functional and causal. Dynamic System Theory has the power to deal with both gestural development and motor complexity, thus making it a good candidate for validating and extending such models. The work of the authors supports that of others and suggests that the underlying mechanism that supports our actions, whether simulated (imagined) or executed, S 3155 is supra-modal in nature (Panayi and Roy 2005). Such diverse knowledge domains are beginning to converge and significantly influence how we now think about the science of intentionality (for review see Panayi 2010). The SCA Model aims to extend our thinking on gestural embodiment, by illustrating how the intersection of biological and physical science in the twenty-first century is impacting on the science of learning. Important Scientific Research and Open Questions Gesture Embodiment, Neuro-atypical Learning, and Field Theories Research into child gesture has established not only its phylogenetic and ontogenetic role, but also the role of gesture in learning. The majority of work addresses cospeech gesture, developmentally, socially, and in pedagogic contexts (e.g., Goldin- Meadow 1993; Goodwin and Goodwin 1986; Hostetter and Alibali 2008; Goldin- Meadow and Cook 2009 cited in Panayi ibid). The SCA Model puts forward two concepts for examination: “the ecology of interaction” and the relationship of actors within those ecologies, that is, “self and other,” within the construct of the entity – “Gesture-As-Action” (GAA). The SCA Model has the capacity to capture properties of a natural system, proposing y (theta) to describe “an open, but bound gesture system” where: y1, y2 and y3 describe children’s capacity for the following: y1 Conception, access, and control of the body action schema, self and other y2 Use of cross-modality to code for action in multisensory space 3 y Ability to execute dynamic transitions between the physical and conceptual world Empirically, gestural repertoires are elicited during children’s engagement in a range of ludic interactions. Children with severe speech and motor impairment due to cerebral palsy (SSMI-CP) have experienced significant damage to the basal ganglia (BG) and the cerebellum (CB) at or before birth. Both areas are implicated in action control and integration. Such S 3156 S Spatial Cognition in Action (SCA) damage affects the nature of children’s movement profile and levels of control, often resulting in: ● Body and cognitive “de-conditioning” ● Quality of life with a high dependence on others for their everyday needs However, given “scaffolded” opportunities to engage corporeally, both neuro-typical (NT) and neuroatypical (NAT) children produce significant repertoires of intentional gestural actions, using a range of spatial action strategies, including: ● Abstraction ● Modulation (Panayi 1998) SCA Model allows for the gesture system y (theta), to be driven by physical constraints and underlying motivation context, rather than by linguistically motivated structures (see ▶ neuro-dynamics section). These spatial cognitive abilities can be exploited by children, to develop their interaction, that is, with inter-actor(s) or artifact(s) in real, imaginary, and hybrid world (see Roy 1996; Panayi ibid). The value of examining neuro-atypical Spatial Cognition in Action lies not only in the potential to inform pedagogic and rehabilitation practice, but also to add to our theoretical knowledge of how the corporeal “brain– body” works (Panayi 2005). The most recent developments of the model re-visit advances in Field Theories that deal with neurodynamics and biosemiotics to examining intentionality of action of the “action ready body,” (Panayi 2010) that could be code independent (Panayi 2011). The ephemeral nature of gesture provides an exciting perspective from which to explore how we perceive, simulate, execute, and evolve our intentionality across ontogenetic, microgenetic, and phylogenetic time scales. Figure 1 illustrates the SCA Model in terms of the proposed components of an open, selforganizing system for intentional action and emergent behavior, together with its learning and evolutionary capacity. Theoretical frameworks, in particular, have the advantage of being able to condense and provide coherence to bodies of related knowledge. Such models are able to describe, interrogate, and simulate aspects of complex ideas and processes. “We need the theory and models or we do not understand what we find” Fuster 2007. Equally, the influence of our practice contributes to the development of our theoretical models. “Rather than conceiving practice as an application of theory, as its consequence, it is, on the contrary, the forerunner that inspires theory, the creator of a theory yet to come. . .” Deleuze What are needed are theories and analytical tools informed by practice, which both: ● Support the re-examination of body–brain (corpo- real) complexity ● Guide our deeper understanding of how our embodied experience influences our actions SCA Neurodynamics of Field Theory I and II Pattern Complexity of Perception, Action, and Cognition Perception, simulation, and execution of action in primates are known to be activated by distributed cortical networks. Spatial Cognition in Action is examined empirically and theoretically at both microscopic (actual sensory inputs) and mesoscopic and macroscopic (through the examination of executed gesture) levels. Collectively these data provided evidence to inform the “body–brain system” from corporeal perspectives. Fuster (1997, 2007 cited in Panayi ibid) proposed that structure–function relationships and interconnectivity across ontogenetic and phylogenetic time scales of the Perception-Action-Cycle (PAC) results from “active engagement moment to moment.” The SCA model proposes that this “moment-to-moment (gestural) action” is supra-modal. Brain system complexity can be described as a network with high distributed connectivity. Such a biological system is “open” and operates “at a distance” from where energy and matter may be exchanged, that is, “dissipative structures” which result from a “breaking of symmetry.” This breakdown allows for emergent, complex, and/or chaotic forms (Prigogine and others). Freeman proposes the use of “neural power dynamics,” where with increasing (neural) power results in increasing order (opposite to thermodynamics), that is, “as neurons interact they constrain each other.” He showed that the “neural patterns of meaning” are by nature “mesoscopic wave packets.” Stimuli deactivate the cortex, activate arrays Spatial Cognition in Action (SCA) S 3157 S Spatial Cognition in Action (SCA). Fig. 1 SCA: Neuro-semiotics of Dynamic, Self-organizing Open System for Intentionality Action and Emergent behavior with learning and “evolutionary” capacity (Panayi 2010. Developed after Roy 1996 and informed by Uexküll 1909; Deleuze and Guattari 1980; Sebeok and Umiker-Sebock 1992; Bouissac 2006; Hoffmeyer 1996/2007; Barbieri 2010) 3158 S Spatial Cognition in Action (SCA) of synaptic networks of neurons, and “transmit” neural energy as “waves.” These wave packets follow trajectories that are demarcated by phase transitions. The system tends to evolve toward maximum energy and order. Amplitude modulation (AM) of 100 ms is thought by Freeman to signify elicitation. Collectively the brain thus has “neural capacity for energy-dependent, self-organizing cortical phase transitions.” Significantly for SCA-learning (simulation and execution of action), these neural arrays could embody aspects of knowledge that are not directly linked to the microscopic sensory inputs. This activity takes place in both sensory and motor cortex and large domains of the human cortex – the brain becoming a “dynamical processor with global distribution of energy.” Importantly, the “dynamics of the cortex is independent of size”; this phenomenon phylogenetically supports the implications that mammalian brains “work in the same way” (Fuster 2007; Freeman 2007 cited in Panayi ibid). Human Interaction Ecologies of Complex External Environmental Patterns Figure 2 illustrates components of pattern complexity (SCA). Figure 3 illustrates simple neurodynamic features involved in PAC (SCA). SCA Neurodynamics of Field Theory III Connectivity, Plasticity, and Development The next stage of SCA was informed key two Field Theories: Dynamic Field Theory (DFT) and Quantum Field Theory (QFT). DFT offers a conceptual and descriptive (mathematical) framework with two main advantages: firstly, as a bridge between “motor control and development into cognitive function,” and secondly, “thinking about representation-in-the-moment.” Neural populations (cell assemblies) are conceptualized as “neural fields” that represent perceptual features, actions, and cognitive decisions (Spencer and Schöner). DFT provides a platform for the interrogation and Simulation / Execution of Intentional Action Neuro-atypical & Neuro-typical Sequences and sub-movements including manipulations and micro-gestures e.g. Ludic Ordered / serial patterns or disordered ‘chaotic’ patterns Perception Action Neural Cyto-architecture and Mechanism With capacity for transforming ‘Thought action’ to ‘Action in space and time’ and vis versa as spatial patterns either veridical, imaginary or hybrid space Distributed Neural Connectivity [DNC] Microscopic Mesoscopic Macroscopic including: Cerebral Cortex (Motor [Mi; Premotor [PM]; Basal ganglia [BG] and cerebellum [CB] coupling allowing for shared decision coarse-fine movements.

In contrast, Quantum Field Theory (QFT) enables the SCA Model to go beyond “representation as coding” in the traditional sense (see Fig. 4). Quanta can be described as “discrete” energy packets that can exist at different states of energy. At the neuronal level, neurons are considered as vast assemblies of interacting “particles”; these particles “can occupy the same place in space,” and thus they are capable of “carrying force;” specifically electromagnetic force (related to action potential firing, that is, “neural forces”) (Freeman and Vitiello 2009). Likewise, wave-based processes have also been postulated at both whole organism and at cellular metabolic level, for example, locomotion, Purkinje cells, and enzyme catalysis. Correspondingly, graphical theoretical techniques are being applied to brain networks with structure (simple) to function (repertoire) together with their interactivity and granularity of these interactions (see review Sporns 2007). Features of interactivity that are of relevance to the SCA Model included: ● Centrality of “Hubs” and their functional connec- tivity could relate to both neuro-typicality and 3160 S Spatial Cognition in Action (SCA) Experience Mediated by (external & Internal) Environment Neuro-atypical & Neuro-typical Movement profiles Spontaneous/background activity Of Spatial Temporal Patterns Macroscopic e.g. EEG, MEG Mesoscopic e.g local field potentials ECoG Microscopic e.g. single cell action potential Attractor Iandscapes:‘cumulative correlation maps’ making possible ‘Intentional Arc’ Abstractions and generalizations Resembles vortices of tornadoes Every point in the dynamic field has amplitude and direction of change in space and time Stimuli destabilizes cortex Stimulus and stimuli independant Force creates neuronal activity Intentional Action Simulated or Executed Neuroatypical & Neurotypical Gesture Repertoires Gestural Action as Executed Action GA-EA Gestural Action as Simulated Action GA-SA SCA Thus, meaning Expression and of sensory transmission of information sensory information is expressed and transmitted as Spatial Patterns of Cortical Activity (SpCA).

These nodes could become instrumental to the stability/instability of the dynamic system. At a neuronal level this “small-world connectivity” or “corticalmicro-states” can support both spontaneous activities (across temporal scales) and complex dynamics in brain-body systems providing a mechanism for brain selection; “dependent on both need and input” (Sporns ibid and in press). Such “small-world connectivity” has been explored through the examination of children’s gestural repertoires. Importantly for SCA, such “wave phenomena,” concepts and network mathematics could provide the mechanism and tools that could mediate learning (see also the section on Human praxis and ontogeny of learning). These structural mechanisms could encompass the neuro-structural constraints of neuro-atypical learners. Thus, target gestures are produced with levels of abstract conceptual coherence and performed corporeally. Both neuro-atypical and neuro-typical children are able to modify features of their gestural repertoires and use a range of dynamic strategies, for example, space–time parameters such as velocity, deceleration, boundaries, rhythmic and synchronous features in terms of “self ” and “other.” Interestingly, the typical rate of gesture production ranges is 3–6 s, thus gesture serves as a robust example of “moment-tomoment” dynamic activity. As with DST, both DFT and QFT can accommodate the existence of emergent phenomena in children’s gestural repertoires, for example, the creation of gestures to explain novel experience such as describing “neologism” related to “inventions” during the re-telling and enaction of an animated cartoon. Extracts from the Child Gesture Corpus (Roy and Panayi) are illustrated in the figures that follow where: Exemplar 1 Target Gesture: “pretend to play the violin,” Gesture Execution: Typically involves interaction with the body (self) taking role of the “other,” that S is, “violin player” and interacting at varying degrees of complexity with a primary imaginary object : “violin,” secondary imaginary object: “bow” and tertiary object: “other” – “audience.” Exemplar 2 Target Gesture: “lasso that steer,” Gesture Execution: Involves the body (self) taking the role of “other,” that is, “Cowboy” and interaction at varying degrees of complexity with a primary imaginary object: “lasso,” secondary imaginary object: “steer,” and tertiary object: “other” – audience. Co-ordination movement strategies: coarse sequence of movement: “lasso the steer” (head, arm, and upper body) and finer submovements (grasp of lasso rope, rotation, and throw of lasso, emotional salience (facial), see Fig. 5). Exemplar 1 Extract Stimulus: First 7 min of animation (Claymation) cartoon “The Wrong Trousers” Dir. N. Park, Aardman Productions. Novel Gesture Repertoire: Child describes a series of novel inventions, for example, “Buzzing for Breakfast,” “Flipping bed,” and “dressing robot,” see Fig. 6. Row One: “Buzzing for Breakfast” Gesture Sequence (a), (b), (c) illustrates an example of compression of gestures to convey both “mise-en-scene” and the “complex idea/novel situation.” The gestures embody dynamics and salient narrative features to describe interaction in imaginary story space. In (a) Gesture (closed fist on chest) indicates that (a) “You/I” are now upstairs (b) bimanual “upstairs” gesture with one arm hand representing “stairs,” other hand/arm represents “you” going up stairs, where Wallace (character change POV) and change of role to Wallace, who is pressing the buzzer c). Row Two: “Flipping Bed” Child becomes “novel object” and enacts most salient feature, that is, “flipping bed” framing and dynamics. Facial expression illustrates the emotional nature of gesture. Row Three: “Dressing Robot” Child takes both the role of Wallace and the “dressing robot” to enact Wallace having shirt (arms), (a) and (b) pullover put on over his head. Body maintains role of Wallace, hands take role of robot arms. From Models to Practice Human Praxis and the Ontogeny of Learning The “organic code hypothesis” of Barbieri (2008 cited in Panayi ibid) offers further potential for development, 3161 S 3162 S Spatial Cognition in Action (SCA) Spatial Cognition in Action (SCA). Fig. 5 Emergent child gesture: Neuro-atypical SCA – Dealing with complexity: Conceptual integration and compression from left to right. Target gesture: pretend to lasso the steer that is, opportunities for experiences and learning that perhaps distinguishes as human. Deleuze and Guattari’s philosophical concept “image of thought” describes learning through “rhizome” connectivity. This connectivity could support both understanding of complexities, for example, space and time that support our actions and give opportunity for “alternative thinking and learning.” At a phylogenetic level, Hoffmeyer proposes the existence of evolutionary advantage through what he terms “semiogenic scaffolding,” that is, semiotic components instrumental in learning and interaction (Hoffmeyer 2007). At a more tangible level, the value of understanding the science behind learning lies in its power to inform a vast array of human activity, for example, from pedagogy, rehabilitation therapies to the development of future interactive technologies. The relevance of the SCA model lies in the theoretical and pragmatic contribution to informing change in practice. The authors argue for an inclusive re-evaluation of how we encourage children’s thinking and action in space. Freire advocated for pedagogy to embrace “dialogue as indispensable to the act of cognition” and essential to “inquiry and creative transformations.” p71. In the SCA model, the term “dialogue” has been extended to include “corporeal dialogue” as action that examines both the nature of gesture and children’s capacity to modulate their action. From an interaction paradigm and pedagogic perspective the SCA Model is informed by two fundamental requirements: ● Need to understand and include both variability and mechanism for developmental transitions ● Imagery/simulation as a critical component of the system dynamics Specifically, Vygotskian “décalage –variability” is described as a mechanism of transition (zones of proximal development). In neo-Piagetian “developmental webs,” identify variability and stability as vital to the “dynamic ways people’s actions differ and change” Spatial Cognition in Action (SCA) S 3163 Spatial Cognition in Action (SCA).

Re-telling and extract of a cartoon narrative with novel gesture to express neologisms and inventions e.g. ‘Buzz for breakfast’ (row 1), ‘Flipping bed’ (row 2), ‘Dressing robot’ (row3/4) (Rose and Fischer 2009, p. 400). Sinha supports the importance of imagery in spatial cognition with semiotic and neo-constructivist theories and arguments, where “radical imaginary is the social imaginary, the foundational source not only of the Vygotskian semiotic mediation of individual cognition, but also of the construction of all social institutions and social objects.” He goes on to suggest that “Such an alternative account of human development is both necessary and possible, and its construction could contribute to both a theoretical and a practical emancipation of imaginative reason . . .” (Sinha 2007, p. 32) Neuro-atypical Learning Capacity Neuro-atypical children have the capacity to access pathways “alternatively,” that is, exploit their cortical area specialization for learning through “practice” or “simulation,” rather than by physical practice in the real (veridical world). (For a derived neurology that underlies gesture see Panayi 2001 and ibid). Such mechanisms could make additional neural resources available to neuro-atypical and neuro-typical children. Coupled with Field Theories and empirical findings, the SCA Model illustrates how the body–brain has capacity for distributed responsiveness and plasticity. The postulated neurodynamic and neurosemiotic system components and their interactivity are brought together schematically in SCA. Figures 1–6 illustrate how, through control of their spatial cognition, they can deal with patterns of complexity and interaction that result in intentional action as gesture.

Fig. 7 SCA ontogeny of learning Existing pedagogy and therapy for neuro-atypical communicators and movers have largely followed models influenced by the traditional medical model and pedagogic thinking, often such practices being inaccessible to dynamic assessment. We need to consider how we can develop both thinking and practice that tend toward and drive the direction of pedagogy, therapy, and future interactivity, in ways that can capitalize on both: ● The supra-modal nature of our spatial cognition and corporeal action ● The diversity capacity of children The implications of such research which will undoubtedly change not only the way we understand how we interact with our veridical, imaginary, and hybrid worlds, but also how we will evolve these interactions (see Fig. 7, SCA – Ontogeny of Learning). Spatial Cognition in Action (SCA) From a neuro-dynamic perspective further research is needed to understand both the nature and the significance of pre-motor activity and its implication for our spatial cognitive development and learning. Three key areas are proposed for future scientific research and open questions with regard to the neurobiology of underlying systems of gesture rooted in action: – Performed action as imagined (simulated action) from an allocentric (action of others) or egocentric (action of self) or explicitly executed – Language understanding, in particular, for semantics relating to action (verb or noun) in relation to self or other (including artifacts) – Exploration of the role of physical and imaginary or simulated experience These domains together with the impact of the advances in the nature of our technology-mediated interaction hold a potential to change our pedagogy and rehabilitation and future technology design practices, now and beyond the twenty-first century.

Spatial Contiguity ▶ Split-Attention Effect Spatial Learning DAVID R. BRODBECK Department of Psychology, Algoma University, Sault Ste. Marie, ON, Canada Synonyms Cognitive mapping; Spatial memory Definition Spatial learning refers to the process by which an organism acquires a mental representation of its environment. Spatial learning has been found in both vertebrate and invertebrate species. Theoretical Background The first systematic studies of learning by psychologists such as Thorndike, Skinner, and Pavlov concentrated on simple stimulus–response (SR) or stimulus–stimulus (SS) connections. In such a framework, an animal would learn to associate a neutral stimulus with a biologically relevant one (classical or Pavlovian conditioning) or would associate a behavior with its outcome (operant conditioning). However, when an animal learns its position in space, such simple associative processes are not sufficient to explain how organisms learn locations. The organism then usually forms some sort of representation of the environment consisting of the relationship of specific stimuli in the environment to the animal and to each other. This representation was originally termed a cognitive map by Tolman (1948). Tolman found that when given experience on a maze without receiving a reward, rats showed similar performance to another group of rats that were given a reward upon completion of the maze. Experience in the environment in question then is the necessary factor in spatial learning, not simple SR or SS associations. These cognitive maps are thought to be not unlike real maps, showing geometric relationships between Spatial Learning objects in the environment, with features added. The animal can then in a sense look up where it is on its map and determine where to go next, where home is, where food is, etc. So, the animal learns both distance and direction to and from various landmarks in the environment. The geometric part of the representation may be served by a specialized module. While the simple SS or SR approaches to learning are not that useful when modeling spatial learning, it may be possible to think of different spatial locations and features in the environment as stimuli not unlike those used in mathematical models of associative learning such as the Rescorla–Wagner model. The animal could weight various sources of information such as compass direction, proprioceptive cues, etc., differently, allowing it to learn where some goal is in space (Cheng et al. 2007). Important Scientific Research and Open Questions While Tolman’s (1948) work was groundbreaking and quite against the more popular behaviorist notions of the time, it was not until the 1970s that research on spatial learning really took off. At that time, Olton and Samuelson (1976) tested rats on a radial maze. This maze, which has baited arms that radiate out from a central platform like the spokes of a wheel was then used in literally hundreds of articles after 1976. Typically rats, and most every other species tested, performed very well on such a maze, usually learning to visit arms in a seemingly haphazard order (rather than say clockwise or counterclockwise until all the arms are visited) yet made few mistakes. These results led many to postulate that spatial memory was somehow different than other forms of learning. Indeed, when the predictions of and SR type model and a more general cognitive mapping model are put in opposition, the cognitive mapping model has won out. There are many possible stimuli that can be learned about in spatial learning. Beacons are stimuli that are directly navigated to. For example, if you wanted to travel to a given building in a city, the building itself is a beacon. Landmarks are stimuli that are relatively close to the goal but are not themselves the goal; instead, landmarks indicate direction and distance to the goal. The question of what the content of learning is in a spatial situation has been addressed especially by Ken Cheng and his colleagues. When rats are placed S in a rectangular arena that has a buried piece of food in one corner, they are more likely to make any search errors to the rotational opposite side (e.g., if the baited corner was the top left of the box, they make errors to the bottom right) rather than a reflection (in this case the bottom left). Such errors were present even when the features of the box, patterns on the walls for example, were different for each wall. This lead Cheng (1986) to conclude that geometry was encoded first, and responded to preferentially over other types of cues. Similar results have been found with young children (around 3 years old) searching for a toy in a room with three white walls and one blue wall. However, adults, when confronted with this task in the presence of a blue wall, use that cue over geometry (Hermner and Spelke 1994). Such results have lead many researchers to conclude that spatial learning is served by a specialized geometric module in many species (Cheng et al. 2007). It is becoming clear that spatial learning is not mediated solely by geometry, landmarks, or beacons, but by a whole host of cues (e.g., optic flow, proprioceptive cues) that, for any given location, are more or less useful. A weighted average of the metric values of the various cues can be used to point to a particular location. Cheng et al. (2007) suggest that the weightings follow Bayesian principles. Spatial learning is mediated quite clearly by the hippocampus. The discovery of place cells which fire only when a rat is in a given spatial location is one of the many pieces of evidence suggesting this (O’Keefe and Nadel 1978). Species that rely extensively on spatial learning in their natural environment have not only been found to prefer to solve learning problems spatially, but they also have a larger hippocampus than animals that rely less on spatial learning in their natural environment. Hippocampal lesions in many species disrupt spatial learning, usually making it impossible. These lesions do not always affect nonspatial learning, though this is not universal. Indeed, in humans, the hippocampus not only serves a spatial function but is also crucially important in episodic memory consolidation.

From this view, neurons in the spinal cord have little capacity to adapt and instead respond in a rigid manner over time. Experimental evidence has discounted this view and demonstrated that neural mechanisms within this region of the central nervous system can adapt to new environmental relations and, in this way, meet the criteria for learning. These criteria require evidence that a behavioral/ physiological modification (1) depends on the organism’s experiential history, (2) is neurally mediated, and (3) outlasts (extends beyond) the environmental contingencies used to induce it (i.e., the experience has a lasting effect on performance). Research has shown that spinal neurons can support behavioral phenomena that meet these criteria, and in this way, demonstrate spinal learning (for further information on this, and other topics discussed below, see Patterson and Grau 2001). Theoretical Background Researchers have typically used three techniques to study whether a system is capable of learning: stimulus S preexposure, Pavlovian (classical) conditioning, and instrumental conditioning. Each of these techniques refers to a kind of methodology, designed to ascertain whether the system is sensitive to a particular kind of environmental event, or relation, and whether the experience has a lasting impact on how the system operates. To study spinal learning, researchers typically isolate the lower (lumbar-sacral) spinal cord from the brain by surgically cutting (transecting) the cord below the shoulders (a mid-thoracic transection). This procedure blocks neural communication along the sensory/motor pathways that carry signals to and from the brain, producing a paraplegia that blocks (brain-dependent) conscious sensations from stimuli applied below the waist and the ability to voluntarily perform a motor response. Studies examining the consequences of stimulus preexposure typically monitor how the behavioral response elicited by a particular stimulus changes as a function of experience (defined as the duration of exposure and/or number of presentations). As a result of this experience, the behavioral/physiological response to the stimulus may become weaker (habituation) or stronger (sensitization). In its simplest form, the only factor that matters is experience with the stimulus alone – its relation to other stimuli, or the behavioral response, is irrelevant. Because there are no associations with other events or responses, this type of learning is often characterized as nonassociative in nature. Over a century ago, Sherrington (1905) showed that spinal reflexes exhibit habituation. Decades later, Groves and Thompson (1970) built on this foundation, demonstrating that neurons within the spinal exhibit both habituation and sensitization, and that these phenomena abide by many of the same principles that govern their action in other behavioral paradigms. The lumbosacral spinal cord contains an inner region of neurons (the gray matter) that can organize and execute some simple behaviors in the absence of input from the brain. For example, a weak shock to a rear paw can elicit a withdrawal (flexion) response in a spinally transected animal. Similarly, a noxious thermal stimulus applied to the tail will elicit a withdrawal response. In both cases, physiological experiments have shown that the behavioral response depends on a neural (reflex) arc that passes through the spinal 3169 S 3170 S Spinal Learning cord. Because the behavioral response depends on spinal neurons, and can be elicited after communication with the brain has been severed, it is called a spinal reflex. Using this preparation, researchers have shown that repeated presentation of a weak shock causes a lasting, neurally mediated, decline in response magnitude (habituation). Conversely, exposure to an intense shock can cause an increase in response magnitude (sensitization). More recently, researchers discovered that a variety of noxious events (e.g., peripheral inflammation or injury) can sensitize pain-like (withdrawal) behavior. This enhanced behavioral reactivity has been linked to an increase in neural excitability within pain (nociceptive) fibers and spinal neurons (central sensitization) and is thought to contribute to the development and maintenance of persistent pain. Whether spinal neurons can support Pavlovian conditioning has proven much more controversial. Pavlovian conditioning provides a method to assay whether a system is sensitive to stimulus–stimulus (S-S) relations. In the prototypic case, this is studied by pairing a cue (the conditioned stimulus [CS]) that has relatively little behavioral effect with a biologically significant event (the unconditioned stimulus [US]). For example, Pavlov showed that pairing an auditory cue (the CS) with food (the US) endowed the CS with the capacity to generate a conditioned salivation response (the conditioned response [CR]). Pavlov assumed that this learning depended on higher-level, cortical, processes. E. Culler challenged this view a decade later, presenting evidence that spinal neurons may be sensitive to S-S relations (reviewed in Patterson 2001). But questions arose and few took the work seriously until Thompson and his students reexamined the issue 3 decades later. In spinally transected animals, they paired a weak shock to the thigh (the CS) with an intense shock to the toe pads (the US). Over trials, the paired CS elicited a progressively stronger flexion response (the CR). When the CS was presented alone (extinction), the CR waned. Subsequent studies confirmed that learning depended on the CS-US pairing and demonstrated a range of Pavlovian phenomena, including differential conditioning, latent inhibition, blocking, and overshadowing. While most would agree that the spinal cord is sensitive to S-S relations, questions remained. Those wedded to the philosophical school of associationism sought evidence that a truly neutral cue, that has no capacity to elicit a CR-like behavior prior to training, could support conditioning and acquire the ability to produce a CR as a result of its association with the US. From this view, any example of conditioning that involved the modification of a preexisting reflex did not demonstrate true associative learning and was relegated to the domain of conditioning artifacts with the label of alpha conditioning. This view held sway for many years and raised doubts as to whether spinal neurons could support “true” Pavlovian conditioning, because in the spinal preparation, the CSs routinely elicited a CR-like response prior to training. This view began to shift in the mid-1980s, with evidence of Pavlovian conditioning in the invertebrate Aplysia. Here was an example of learning that depended on CS-US pairing and for which Eric Kandel and his associates were uncovering the neurobiological machinery. Yet, purists were troubled because learning in this preparation depended upon the sensitization of a preexisting (CR-like) response. At the same time, electrophysiological studies showed that paradigms thought to meet the behavioral ideal of true conditioning utilized a CS that generated CR-like neural activity prior to training. As the power of these data became clear, the distinction between true associative learning and alpha conditioning loss sway. A more modern view (neurofunctionalism) sees Pavlovian conditioning as a powerful methodology, which can be used to demonstrate a system is sensitive to S-S relations, but recognizes that there are many ways in which a S-S relation can be encoded by the nervous system and that there is little reason to view one as superior to others (Grau and Joynes 2005). As this view has gained strength, so too has the acceptance that the spinal cord can learn. The idea that spinal neurons are sensitive to response–outcome (R-O; instrumental) relations has proven equally controversial. In instrumental learning, there is a relationship between a particular R (e.g., pressing a bar) and an O (e.g., obtaining a food pellet). As a result of this R-O relation, a rat will typically exhibit an increase in bar pressing. Similarly, if extending one hind leg (the R) causes a pain-inducing shock (the O), the subject will quickly learn to maintain the leg in a flexed position that minimizes net shock exposure. What is surprising to many is that the second example of learning does not require a brain. Demonstrations of spinally mediated instrumental learning typically use three groups. Master rats receive Spinal Learning shock whenever one hind limb is extended (controllable shock). Another group is experimentally coupled (yoked) to the master rats and receives shock at the same time, but independent of limb position (uncontrollable shock). A third group remains unshocked during training. Master rats exhibit a progressive increase in flexion duration over the course of 30 min of training. Yoked rats respond, but do not exhibit an increase in flexion duration (the index of learning). Subjects are then tested with controllable stimulation applied to the opposite leg. Master rats typically exhibit some benefit from the earlier training (a form of positive transfer) relative to the previously unshocked controls. Yoked rats generally fail to learn, a form of negative transfer reminiscent of learned helplessness. The term “instrumental conditioning” has its roots in the reflexive tradition of Edward L. Thorndike and Clark L. Hull. An alternative term, operant learning, was coined by B. F. Skinner, who saw this category of behavior as being emitted, not elicited (the latter he called respondent behavior). In an ideal operant situation, a range of behaviors could be arbitrarily shaped using a variety of outcomes (reinforcers, both appetitive and aversive). In reality, most examples of operant behavior are more biologically constrained than Skinner realized. R-O learning in the spinal cord depends on an elicited behavior and lacks flexibility – it is highly biologically constrained. It does, nonetheless, depend on the R-O relation and meets the other criteria for learning. Extracting ourselves from this conceptual morass requires that we recognize: (a) that instrumental conditioning refers to a methodology that can be used to demonstrate that the R-O relation matters; and (b) that the terms instrumental and operant should not be treated as synonyms. All examples of operant behavior will likely meet the behavioral criteria for instrumental behavior, but the converse is not true. It appears that neural systems can encode R-O relations in many ways and that simpler systems are generally more biologically constrained in their behavioral repertoire. Over the last 20 years, researchers have uncovered many of the neurobiological mechanisms that underlie spinal cord plasticity. Much of this work has focused on the identification of the neurochemical systems involved in central sensitization. These studies have shown that electrophysiological phenomena (e.g., long-term potentiation [LTP]) and neurochemical mechanisms (e.g., NMDA receptor-mediated plasticity) discovered within S 3171 brain structures involved in learning and memory (e.g., the hippocampus) are also observed within the spinal cord (Ji et al. 2003). Paradoxically, these neurobiological discoveries have led to a shift in thinking that 50 years of behavioral work could not accomplish, leading many to assume that spinal neurons must be capable of learning – because the required neurobiological mechanisms are present. Important Scientific Research and Open Questions Current work in the field of spinal learning is focusing on three issues: further detailing the behavioral limits of spinal learning, examining the underlying neurobiological systems, and evaluating the clinical implications. New behavioral work has shown that spinal neurons can discriminate regular (predictable) versus irregular (unpredictable) stimulation. Further, learning about temporal regularity appears to engage a protective effect that can enable subsequent learning and counter the development of neuropathic pain. Studies examining the neurochemical systems involved in central sensitization are leading to the development of new drug treatments to counter pain. Other work has shown that stimulation after a spinal cord injury can influence recovery; just as uncontrollable shock impairs subsequent learning in transected rats, it inhibits recovery after a contusion injury (a bruising of the spinal cord caused by a moderate impact that emulates the type of injury often observed in humans). Researchers have also discovered that neurons within the lumbosacral spinal cord can support stepping behavior and that this system can be retrained after injury. This discovery has led to new rehabilitative techniques that emphasize behavioral training (e.g., stepping on a treadmill) after injury and has been shown to foster recovery.

Split-Attention Effect PAUL AYRES1, GABRIELE CIERNIAK2 1 School of Education, University of New South Wales, Sydney, Australia 2 Knowledge Media Research Centre, Tübingen, Germany Synonyms Spatial contiguity; Split-attention principle; Temporal contiguity Definition Split-attention occurs when learners are required to split their attention between two or more mutually dependent sources of information (e.g., text and diagram), which have been separated either spatially or temporally. If information of each source is essential for understanding the topic, all information given must be mentally integrated by the learner for learning to occur. However, this forced integration process increases demands on the learner’s working memory (WM) and can impact negatively on learning. To create effective learning environments instructional designers must avoid split-attention by externally integrating the different sources of information together into a single integrated source of information. For example, an integrated format can be achieved by embedding written instructions within a diagram (avoiding spatial separation) or aligning spoken text with the targeted picture during a multimedia presentation (avoiding temporal separation). The split-attention effect occurs when a single integrated source of information enhances knowledge acquisition better than separated sources of information. The split-attention principle says that several separated sources of information should be replaced with a single integrated source of information. Theoretical Background Cognitive load theory (CLT, see Chapter ▶ Cognitive Load Theory) has defined three types of cognitive load: intrinsic, extraneous, and germane (Sweller et al. 1998). Intrinsic cognitive load is the load imposed on WM by the complexity of the materials to be learned. Complexity depends on the number of interacting elements. Element interactivity is measured by the number of elements of information that must be simultaneously processed in WM for learning. Materials with high element interactivity are difficult to learn. Extraneous cognitive load is the load placed on WM by the way the instructional designers construct the learning materials. Inefficient and badly designed materials can be harmful to learning as scarce WM resources are taken up by unnecessary processing. Germane cognitive load consists of the WM resources directly invested in dealing with intrinsic cognitive load (schema creation). By keeping extraneous load to a minimum and maximizing germane load, effective instructional designs can be created. Research into CLT has identified a number of strategies that decrease extraneous cognitive load. One such strategy is the integrated format to avoid Split-Attention Effect split-attention. Split-attention was first identified by Tarmizi and Sweller (1988) who found that conventionally structured worked examples (see Chapter on the ▶ Worked Example Effect) were an ineffective method to learn geometry. This finding was unexpected because up to that point, worked examples had been found to be highly effective in other mathematical domains such as algebra. To explain this failure, Tarmizi and Sweller argued that when the textual solutions were written below the diagram, cognitive load was increased. Because of the spatial separation between diagram and text, learners studying the worked examples were forced to mentally integrate information on the diagram with the written solution steps. It is important to note that both sources of information were unintelligible by themselves. Both were needed to fully understand the solution. The mental integration of the two sources increased WM load (creating an extraneous cognitive load) because of this unnecessary processing. In particular, learners were forced to search for locations in both the text and diagram and match them. Search processes require WM resources. Traditional forms of geometry solutions usually involve both a diagram and separated lines of mathematical text (solution steps). However, Tarmizi and Sweller overcame this problem by integrating the text into the diagram. Using this integration strategy, worked examples were then shown to be effective. Other CLT-based research extended the findings into others domains of mathematics and science (see Sweller et al. 2011). One particular study of importance was conducted by Chandler and Sweller (1991) into learning about the human heart and lungs. They found that an integrated format was not superior to a splitattention format if redundant information was included. In their experiment, both the diagram and text contained information that was identical. In this case the text was not needed to understand the diagram. Only when the redundant text parts were removed did the integrated format become superior to a split-attention format. The redundancy effect is another CLT effect that has been widely researched (see Sweller et al. 2011). The redundancy finding was important because it demonstrated that the splitattention effect is severely compromised by redundant information. The research reported so far describes experiments that were conducted solely with paper-based materials. S Later research into the split-attention effect also used computers. In a number of experiments completed by Sweller and Chandler (1994, 1996) computer manuals were shown to be a common source of split-attention. Reading from a manual while attending to information on the computer screen while performing various computer actions inevitably leads to split-attention. Sweller and Chandler demonstrated that successful integration could be achieved by disregarding the computer altogether by using a modified manual that included integrated texts and diagrams of the computer screen and keyboard. Further research demonstrated that the integrated materials could also be solely displayed on the computer screen without a manual. A second finding in the Sweller and Chandler studies was that the splitattention effect only occurred when the materials were high in element interactivity (high intrinsic cognitive load). For low element interactivity materials, the extraneous cognitive load caused by unnecessary processing of separated sources was not sufficient to overload WM and to interfere with learning. Much of the CLT-based research into the splitattention effect has been conducted by John Sweller and his colleagues; however, Richard E. Mayer has also made a significant contribution to understanding this effect. Earlier findings by Mayer showed that in learning about how brakes work or how lightning forms, words and pictures should be integrated together rather than kept separately (for summaries see Mayer 2005). In showing this effect, split-attention scenarios were created by positioning text below the related pictures diagrams or on a separate page. In contrast, the integrated formats consisted of placing text, which describes the action, close to the diagram depicting the action. On transfer tasks, the integrated formats were found to be superior to the split-attention formats with large effect sizes. In Mayer’s studies, evidence was collected that integrating words and pictures leads to superior learning compared with more spatially separated formats. Mayer called this the Spatial Contiguity Principle: “People learn more deeply from a multimedia message when corresponding text and pictures are presented near rather than far from each other on the page or screen.” (p. 195). So far, the research reported above has only included static presentations, whether they are text and pictures, or a computer manual and a computer. Moreover, parallel research has been conducted into 3173 S 3174 S Split-Attention Effect dynamic representations or animations. With more dynamic pictures that show events over time, pictures come and go as the scenarios unfold. Similarly, any accompanying text, be it written or spoken, will also be transitory. Whereas, transitory information provided through animations presents special challenges to the learner; the synchronization of text and pictures is crucial if split-attention is to be avoided. In cases where text and pictures are separated on the screen, i.e., where both are not visible at the same time, WM resources are particularly stretched. If important information, in one mode or the other, has disappeared from the computer screen, the learner must try to hold that information in WM for a period of time, and then match it with the accompanying source of information when it is eventually presented. Hence, information needs to be held in WM as well as relevant searches completed, to match and integrate connected components. It may be that split-attention in an animated environment may have a greater impact than in a static one, where the sources of information can be more easily revisited. Therefore, multiple sources of information that need to be integrated but are separated in time also create an extraneous cognitive load. The temporal separation of information has been extensively researched by Mayer and his colleagues, and is referred to as temporal contiguity. In particular, research into the split-attention effect was extended to include the inclusion of the spoken word (sound). How narratives and pictures are presented together is a crucial consideration in animated multimedia learning environments. In a series of studies (for summaries see Mayer 2005) across different learning domains, Mayer and his collaborators demonstrated that words (narrations) and pictures were more effective if shown simultaneously rather than temporally distant. It did not matter if narration followed the relevant pictures, or vice versa, narrating at the same time as the pictures were shown (integrated format) led to superior learning. These findings, also with large effect sizes led Mayer to articulate the Temporal Contiguity Principle: “People learn more deeply from a multimedia message when corresponding animation and narration are presented simultaneously rather than successively” (Mayer 2005, p. 195). In summary, it can be concluded that separated formats of different sources of information, whether spatially or temporally separated, lead to inferior learning compared with integrated formats. The splitattention effect has very strong implications for instructional design in multimedia environments. Whether the medium is animated or static, contains written or spoken text, an integrated approach to the different information sources leads to the best learning outcomes. Important Scientific Research and Open Questions The meta-analysis by Ginns (2006) confirmed the robustness of the split-attention effect. Split-attention was equally likely to occur for spatial and temporal separated materials, both having large effect sizes. No differences were found between static and dynamic materials. Interestingly, learning materials with high element interactivity produced larger effect sizes than those with low element interactivity. As Ginns points out, the studies with low element interactivity tended to lack statistical power, but some evidence did emerge that the effect could occur with low element interactivity. This finding contrasts with the initial studies of Sweller and Chandler who predicted that the splitattention effect, like most effects hypothesized within the CLT framework, would disappear for low element interactivity material. Consequently, this is one area of research that merits further investigation: To what extent does element interactivity moderate the splitattention effect? A basic assumption made by CLT researchers is that the split-attention effect is caused by learners having to complete unnecessary processing by trying to align the two or more separated materials together. Thus, harmful extraneous cognitive load is created from the number of visual search processes that need to be completed during this cognitively demanding alignment. Although, the negative influence of searching is a very plausible explanation, little direct evidence confirming this hypothesis has been collected. However, with the more recent development of sophisticated eye-tracking apparatus researchers are starting to investigate the visual search patterns of learners when confronted with split-attention materials. Hence, another open question focuses on visual search: To what extent is the split-attention effect caused by visual search within and between the different sources of information?

Spread of activation is a method for searching associative networks, neural networks, or semantic networks that is based on supposed mechanisms of human memory operations (Collins and Loftus 1975). Theoretical Background The Spread of Activation (SA) model in its pure form is quite simple. It is made up of a conceptually simple processing technique on a network data structure. The network data structure consists of nodes connected by links, as depicted in Fig. 1. Nodes model objects or features of objects of the real world to be represented. Nodes are usually labeled with the name of the objects they intend to represent. Links model relationships between nodes and they can be labeled and/or weighted. The connectivity pattern reflects the relationships between objects and/or features of objects of the real world to be represented. A link usually has a direction, a label, and/or a weight assigned according to a specific direction. This representation structure is very similar to a Semantic Network, but it is more general than a Semantic Network and it could represent a more generic Associative Network. The processing technique is defined by a sequence of iterations like the one schematically described in Fig. 2. Each iteration is followed by another iteration until the process is halted by the user or by the triggering of some termination condition. An iteration consists of one or S 3176 S Spread of Activation Theory i Wij j Spread of Activation Theory. Fig. 1 The network structure of a SA model In the pre-adjustment and post-adjustment phases, which are optional, some form of activation decay can be applied to the active nodes. These phases are used to avoid retention of activation from previous pulses, enabling to control both activation of single nodes and the overall activation of the network. In fact, they implement a form of “loss of interest” in nodes that are not continually activated. The spreading phase consists of a number of passages of activation weaves from one node to all other nodes connected to it. There are many ways of spreading the activation over a network (for an overview see Preece 1981). In its more simple form, on a single unit level, Spread of Activation consists first in the computation of the unit input, calculated as: Ij ¼ Start n X Oi  wij i¼1 Pre-adjustment Spreading Pulse Post-adjustment Termination condition Not satisfied Satisfied Stop Spread of Activation Theory. Fig. 2 The pure SA model more pulses and a termination check. What distinguishes the pure Spread of Activation model from other more complex models of searching on networks is the sequence of actions which composes the pulse. In fact, a pulse is made up of three phases: 1. Pre-adjustment 2. Spreading 3. Post-adjustment where Ij is the total input of node j, Oi is the output of unit i connected to node j, and wij is a weight associated to the link connecting node i to node j. The input and the weight are usually real numbers; however, their numerical type is determined by the specific requirements of the application to be modeled. In particular, they can be binary values (0 or 1), excitatory/inhibitory values (+1 or 1), or they can be real values indicating the strength of the relation between nodes. Usually the first two of these options are used in connection with networks with labeled links, like for examples Semantic Networks, where the semantic value of the relation represented by the link determines, in the context of the application, the value to be associated to the link. The last option is mainly used for Associative Networks, where there is only one generic type of association that needs to be properly weighted. After a node has computed its input value, its output value must be determined. The numerical type of the output of a node is also determined by the requirements of the application. The two most used cases being the binary active/non-active type (0 or 1) and the real value type. In Spread of Activation models, there is usually no distinction between “activation” or “output” of a unit. The activation level of a unit is its output value. This is usually computed as a function of the input value: Oj ¼ f ðIj Þ There are many different functions that can be used in the evaluation of the output; some examples are Spread of Activation Theory Linear function Step function S 3177 Sigmoid function Spread of Activation Theory. Fig. 3 Some commonly used activation functions depicted in Fig. 3. The most commonly used function in pure Spread of Activation models is the threshold function. It is used to determine if the node j has to be considered active or not, and thus produce an output. The application of the threshold function to the above formula in the case of binary value units gives:  0 Ij < kj Oj ¼ 1 Ij > kj where kj is the threshold value for unit j. The threshold value of the activation function is application dependent and can vary from node to node, therefore the notation kj for the unit threshold has been used. After the node has computed its output value, it spreads it to all the nodes connected to it, usually sending the same value to each of them. Pulse after pulse, the activation spreads over the network reaching nodes that are far from the initially activated ones. After a determined number of pulses have been fired, a termination condition is checked. If the condition is verified the Spread of Activation process stops, otherwise it goes on for another series of pulses. The Spread of Activation process is therefore iterative, consisting of a sequence of pulses and termination checks. The result of the Spread of Activation process is the activation level of nodes reached at termination time. The interpretation of the level of activation of each node depends on the application and, in particular, on the characteristics of the object being modeled by that node. The pure Spread of Activation model presents some important drawbacks: ● Unless controlled carefully by means of the pre- adjustment and the post-adjustment phases the activation ends up spreading all over the network. ● The information provided by the labels associated to the links is not used, that is, there is no use of the semantics of the associations. Thus, it is difficult to implement some form of inference based on the semantics of associations. These problems can find solutions by taking into account in the processing technique the diverse semantics of the relations among units. This can be achieved using the information provided by the labels on the links and by processing links in different ways according to their semantics. It is possible in this way to implement some form of heuristics, or to spread activation on the network according to some inference rules. A common way of implementing a processing technique which spreads the activation according to rules is by means of constraints on the Spread of Activation. Here are some constraints commonly used: Distance constraints: The spreading of activation should cease when it reaches nodes that are far away in terms of links covered to reach them from the initially activated ones. This corresponds to the simple heuristic rule that the strength of the relation between two nodes decreases with their semantic distance. Relations can be classified according to their distance in term of links. Relations between two nodes directly connected are called first-order relations. Relations between two nodes connected by means of an intermediate node are called second-order relations, and so on. It is common to consider only first-, second- and, at most, third-order relations, although this is application dependent. Fan-out constraints: The spreading of activation should cease at nodes with very high connectivity, or fan-out, that is at nodes connected to a very large number of other nodes. The purpose of this constraint is to avoid a too wide spreading which could derive S 3178 S Spread of Activation Theory from nodes with a very broad semantic meaning and therefore connected to many other nodes. Path constraints: Activation should spread using preferential paths, reflecting application-dependent inference rules. This can be modeled using the weights on links or, if links are labeled, diverting the activation flow to particular path while stopping it from following other less meaningful paths. Activation constraints: Using the threshold function at a single node level, it is possible to control the spreading of the activation on the network. This can be achieved by changing the threshold value in relation to the total level of activation over the entire network at any single pulse. Moreover, it is possible to assign different threshold levels to each unit or set of units in relation to their meaning in the context of the application. Although this may cause an increase in the number of computations, it makes possible to implement various complex inference rules. Referring to Fig. 2 these constraints can be seen as acting during the pre-adjustment phase (this is the case for distance, fan-out, and path constraints) or during the post-adjustment phase (mainly for activation level constraints). Therefore, they can be considered as an enhancement of the pure Spread of Activation model. Another more practical advantage deriving from the fact that the activation does not spread over the entire network is that it permits a reduction of the computational effort of the spreading, because only a small portion of the units become active and send activation to other units. A further enhancement of the pure SA model can be obtained by means of feedback from an external source. In this case, an external evaluation of the activation level of some units or of the entire network provides some constraints that would be difficult or impossible to implement in the form of automatic rules. This external feedback can be due to another process or can be provided by the user of the system. The user evaluates the activation level reached by some nodes and modifies it according to his or her requirements. This may result in a following spreading of activation over particular user-selected paths that differ from those specified by the predetermined path constraints. From this point of view, the Spread of Activation model adapts itself to the specific user’s needs. This model is particularly useful in application where there would be too many inference rules to be represented in the form of constraints and where it is necessary to provide an external control by means of a user’s evaluation of the results. The use of feedback from user can be implemented either in the preadjustment phase, so that the user directs the spreading of activation of the pulse, or in the post-adjustment phase, enabling the user to evaluate the result of the spreading and direct the following pulse accordingly (Preece 1981). Important Scientific Research and Open Questions The Spread of Activation theory has been applied with different level of success in different areas of research, namely Cognitive Science, Databases, Artificial Intelligence, Psychology, Biology, and Information Retrieval (IR). The application of the Spread of Activation theory to Information Retrieval is one of the most challenging and promising (see Crestani 1997 for a perhaps out-of-date review of this area of research). The use of Spread of Activation in IR is based on the existence of maps specifying relations between terms or between documents, as the case may be. Nodes correspond to terms, documents, articles, journals, subject classifications, authors, and so forth. There is no homogeneity in the network. A node can represent anything. Links indicate the association of a node with another node, as, for instance, an author with a document he/she wrote or a document with a document it cites. Specific link types include term occurrence, document publication, term assignment by indexing, document authorship, document assignment to classification, document citation, and so forth. The set of node types and link types is determined by the data available and by the purpose of the application. The representation structure is therefore application specific and the same structure cannot be applied to different applications. It is also important to note that relationships could actually be expressed by a pairs of links. Authorship, for instance, can be represented by both “authored by” and “is author of ” links. Both links in such pairs connect the same two nodes, but their source and destination roles are reversed. Specific processing rules may inhibit activation in either direction, use them in different ways, or associate different weights with the different directions. Given such a complex representation structure, it has been demonstrated that the best retrieval results Stability and Change in Interest Development can be obtained by a Spread of Activation process which uses some of the constraints described above and, in particular, path constraints (Preece 1981). Much of the effectiveness of the process is, however, crucially dependent on the availability of a representative network. The problem of building a network which effectively represents the useful relations in terms of the Information Retrieval aims, has always been the critical point of many of the attempts to use Spread of Activation in Information Retrieval. These networks are very difficult to build, to maintain, and keep up to date. Their construction requires in-depth application domain knowledge that only experts in the application domain can provide. Furthermore, their construction is a very expensive and time-consuming process that results almost impossible for large collections and/or collections spanning over a large application domain.

PhD thesis, University of Illinois, Urbana-Champaign Spreading Activation Theory ▶ Spread of Activation Theory SR Learning ▶ Human Contingency Learning Definition Interest development is an area of scientific inquiry, which seeks to explain the normative developmental processes underlying how people become interested and subsequently choose to pursue different vocations and careers. Vocational interests date back to Parsons’ (1909) model of assisting individuals in matching their interests and abilities to specific occupations and are generally viewed as underlying motivational factors that manifest in preferences for different activities. The common assumption with regard to vocational interests is that the better the match of one’s interests and abilities with an occupation, the better the person’s satisfaction and the greater the job performance. Interest development is most often evaluated through the use of psychological interest measures, which assess preferences (i.e., liking) or aversion (i.e., disliking) related to topics such as, school subjects, occupational preferences, occupational expectations, anticipated occupations, activities, and general interests. Researchers who examine stability and change in interest development are primarily concerned with changes in interest over time and throughout the lifespan. Theoretical Background S-R Learning ▶ Routinized Learning of Behavior Interests are represented using two very different approaches: one empirical and the other theoretical. The Strong Interest Inventory (Harmon et al. 1994) is S 3180 S Stability and Change in Interest Development perhaps the best example of the empirical approach, as it uses a wide variety of empirically derived items to match individuals with occupations. Conversely, the theoretical approach measures theory-based constructs derived from a much smaller number of aspects that are then used to understand interests and apply these to the world of work. John Holland’s theoretical model (1985) serves as the most prominent example of this approach and is widely adopted throughout the field of interest development. Holland posits that six different personality/interest types exist – the six types are Realistic, Investigative, Artistic, Social, Enterprising, and Conventional, commonly referred to using the initials RIASEC – and that individuals express differing amounts of each of these types. There are two general approaches to differentiating interests: person-environment models (Holland 1985) view interests as a fairly stable trait-like expression to be assessed and matched to an environment, while developmental models (e.g., Savickas 1999) view interests as a function of maturation and interaction with the environment. Thus, one set of models stresses stability (person-environment) while the other set of models (developmental) stresses change. Although proponents of each theoretical school interpret the relevance of stability and change in interests in a somewhat different manner, most vocational theorists agree that the developmental focus of interest development necessitates an examination of both stability and change because it is not necessarily true that stability is defined by the absence of change. Any examination of change or stability over time is not complete unless the following five types of change are examined. Change is most often defined by a change in mean scores and the examination of how an individual’s scores increase or decrease over time – this type of examination is also known as absolute stability. This is different from the examination of relative stability, which is usually assessed using test-retest correlations to study changes (or the lack thereof) in one’s relative position in a distribution over time. Where absolute stability is concerned with changes in an individual’s scores, rank-order stability is concerned with one’s position within a distribution and whether that position has remained relatively similar to others within the distribution. This concern with the rank ordering of an individual is also often referred to as rank-order stability. A third-type of change is the change of relative ordering of different scale scores relative to one another (i.e., profile stability). Profile stability focuses on the relative profile shape of an individual and whether changes in relative subscale order remain similar upon consecutive administrations of a measure. For example, if an individual’s profile scores remain relatively unchanged upon consecutive administrations, then this result is interpreted as evidence of profile stability. Another type of change is structural change, which examines the interaction between an individual’s scores and the structure of a specific psychological measure. Structural change is concerned with the relations among the scales and items found on a particular measure and its proponents presuppose that evidence of change resides within the instrument used to assess a particular construct. The findings of Tracey and Ward (1998) are an example of a change in the structure of a scale where the factor analyses of young children were different from those of adolescents and, thus, there were observed changes in the relation of the items in a scale. The final type of change is external to any scale and involves change in the relation of the scale with outside variables; in career assessment this is often achieved by examining relations of interest scales with outside variables such as, self-efficacy, career decision-making, and career choice. Important Scientific Research and Open Questions Scientific research examining stability and change in interest development indicates that there is evidence of stability in adult populations. Conversely, in the period of childhood and adolescence there is evidence of both stability and change. In general, most researchers studying interest development agree that interests become more stable the older people become, eventually reaching a plateau around the ages of 18–20 years of age. The commonly held view is that interests are highly stable and change little after the ages of 25–30 years. However, questions remain about normative developmental trajectories in childhood and adolescence with regards to interest development. Longitudinal research in this area has shown at least moderately stable differences in interests across time when examined from both interindividual and intraindividual (i.e., profile) perspectives. When considered alongside the relatively stable scores witnessed among children Stability and Change in Interest Development and adolescents – especially at the younger ages – these results may be viewed as support for the trait-like view of interests. Important mean differences in interests over time have also been witnessed. There appear to be a pattern of increasing interest scores on all scales during the elementary school years, usually followed by a drop in middle school, and an increase through high school. Interestingly, times of transition often induce drops in interest scores – entry into middle school and the senior year of high school have both been shown to be times in which scores typically drop. These drops are greater for girls than boys, especially in the areas of scientific interests, which may indicate that girls alter their interests in response to environmental change more than do boys. Interesting structural differences between children and adults also exist. Young children tend to view interests using the dimensions of sex-typing (i.e., is the activity a boy activity or a girl activity?) and activity locus (i.e., does the activity occur in school or out of school?). However, as children age, a pattern has been witnessed using aggregate examinations as well as individual ideographic examinations toward increasing fit with RIASEC structure and types – a valid and widely endorsed proxy for normative interest development in adolescents and adults. Furthermore, structural stability tends to be stable by eighth grade and is similar across gender and ethnicity, enabling the valid use of RIASEC scores with all groups, at least in the United States (see Rounds and Tracey 1996, for a review of the structure of RIASEC scores in other countries and cultures). In younger populations, the relation between interest and competence perceptions (i.e., self-efficacy) has emerged as one with several implications for assessment and intervention. In adult populations, interest and competence perceptions appear to be interrelated and seem to affect each other increasingly over time. Conversely, in younger populations, children do not always display this same way of thinking about interest and competence perceptions (i.e., they do not always indicate that they are interested in the things they believe they are good at and vice versa). Since the relationship between interests and competence perceptions has been shown in all age groups to be bidirectional and equal in magnitude – the effect of competence perceptions on interest is equal to the effect of interest S on competence perceptions – interventions geared toward increasing both interest and competence perceptions appear to be warranted. Similarly, whereas adults are able to identify and differentiate those activities (i.e., their likes and competence) that appeal to them from those that do not, children oftentimes tend to like or dislike everything in an undifferentiated manner (i.e., they may indicate that they like most everything or dislike most everything equally). This trend also decreases with age and research has shown that the older individuals become, the more discriminating they tend to be about their preferences. Another area of inquiry in stability and change in interest development is adherence to normative structure (i.e., the extent to which an individual thinks about interests in the same manner as most people) and its effect on career exploration. Findings in this area indicate that children engage in less career exploration than their adolescent and adult counterparts, and individuals in college whose thinking deviates from the normative structure of interests exhibit more career indecision than those who do adhere to the normative structure. These findings lend themselves to further areas of inquiry into the effect of structural adherence on interests and career exploration at key points over time (e.g., how does structural adherence affect career exploration at times when interest is low – for instance the first year of middle school), which may be key in guiding interventions designed to have an effect on variables such as the aforementioned relationship between interests and self-efficacy. Although a great deal is known about stability and change in interest development, there are still many questions to be answered, specifically about the finer discriminations that occur as a result of normative and nonnormative developmental trajectories. Recent research has provided important insights into the process of interest development – indeed, insights that provide a more thorough and multidimensional representation of the process of interest development – however, it is essential that more is learned about what should be expected to change at what times and to which populations interventions should be geared.

TURK-BROWNE Department of Psychology, Princeton University, Princeton, NJ, USA Synonyms Associative learning; Contextual cueing; Segmentation; Unsupervised learning Definition In cognitive psychology and cognitive neuroscience, statistical learning (SL) refers to the extraction of regularities in how features and objects co-occur in the environment over space and time. Such learning may be important for detecting and representing higherorder units of perception, such as words, scenes, and events. SL is defined by three criteria: First, it can operate over undifferentiated input, where only spatial and temporal probabilities can be used to determine which parts of the environment go together; other segmentation cues, such as grouping, are not required. Second, SL occurs incidentally as a by-product of perception, without intentional effort or conscious awareness. Third, SL is concerned with extracting how Statistical Learning in Perception particular features and objects co-occur, resulting in knowledge about relationships between specific stimuli. These properties make SL well suited to the continuous and noisy sensory input we receive from the world. Theoretical Background Perception is concerned with interpreting information conveyed by our senses about the external environment, whether listening to music, enjoying a good meal, or recognizing a friend’s face. Because we live in natural environments that have been stable for thousands of years, and we tend to inhabit the same artificial environments for years at a time, our perceptual systems are repeatedly confronted with very similar sensory information. Over time, repeated aspects of the environment – regularities – tune perception to the types of information most frequently encountered. Such learning may be critical for handling the deluge of sensory information that we experience from moment to moment, allowing for faster and more veridical perception of features and objects that appear briefly (e.g., due to eye movements or motion), or under variable or degraded conditions (e.g., due to changes in lighting or occlusion by other objects). There are many types of regularities. Nature contains regularities in the layout of information (e.g., landscapes have horizontal horizons) and in the laws governing physical interactions (e.g., detached objects must be supported from below). Such natural regularities have altered perceptual systems over evolutionary time. For example, neurons in primary visual cortex are tuned to the properties of images regularly encountered by our species. Regularities also exist in terms of which types of information appear together. For example, academic robes are worn at commencements but not at the beach. Such semantic regularities are learned during our lifetime, and facilitate the recognition of objects that appear in appropriate contexts. Finally, regularities exist in terms of which specific tokens of information appear together. For example, a consistent sequence of landmarks is passed when navigating to a location: “the restaurant is after the cherry blossom tree, the independent bookstore, the busker playing saxophone, on the left”. Importantly, such groupings are arbitrary (no semantic relationship between the objects), and the resulting knowledge is S specific to the learned exemplars (a different tree, store, or person would not be helpful). The focus of this entry is on SL of regularities of this latter kind because: they are prevalent, they can be learned quickly in a laboratory setting, and learning is uncontaminated by preexisting knowledge of natural and semantic regularities. Research on SL has roots in language acquisition. Early work focused on whether the boundaries between morphemes (smallest unit of meaning in a language) could be recovered from how phonemes (basic sounds in a language) are distributed/co-occur over time. The use of such regularities in language acquisition was first empirically tested in developmental psychology (Saffran et al. 1996). In particular, the speech input we get as listeners does not have reliable markers for where words start and stop, and so a key challenge for infants is not only to learn words and their meanings, but to locate the words in a speech stream in the first place. To test whether infants rely on statistical regularities to find word boundaries, a fake language can be constructed from arbitrary three-syllable words, such as tupiro, golabu, bidaku, padoti, which are then combined into a speech stream without pauses between words (e.g., bidakupadotigolabubidakutupiro. . .). Without such segmentation cues, learning of words requires extracting the transitional probabilities between syllables, that is, detecting that transitions within a word (da ! ku) have higher probabilities than those spanning two words (ku ! pa). After two minutes of exposure, infants can tell actual words apart from non-words – syllable sequences that did not occur during listening (e.g., tulaku) or occurred with lower probability (e.g., dakupa). Importantly, each individual syllable in the words and non-words is equally familiar, yet the infants expressed additional familiarity with the words. This study was used to argue that infants have powerful learning abilities, and that language acquisition may be partly experiencedependent. Just as words can be defined by regularities of syllables, there is an analogous “language” of vision: Meaningful units of visual perception, such as scenes and events, can be defined by regularities of objects. Learning of visual regularities has been investigated for both temporal sequences and spatial configurations (e.g., Fiser and Aslin 2001). Temporal sequences arise in vision because events and actions (e.g., catching 3183 S 3184 S Statistical Learning in Perception a flight) are defined by a specific progression of information (e.g., parking garage, ticket agent, metal detector, gate, seat), and because our eyes get information from one part of space at a time – resulting in a temporal sequence as we move our eyes around. SL of temporal sequences in vision is tested by showing a continuous stream of nonsense shapes (e.g., each letter is a shape: ABCGHIDEFABCJKL. . .) that, without observers’ knowledge, has been constructed from shape triplets (e.g., ABC, DEF, GHI, JKL). After a few minutes of exposure to the stream, familiarity is higher for triplets (e.g., ABC) than for recombinations of the same shapes (e.g., AEI). Again, since each individual shape is equally familiar, additional familiarity for triplets indicates statistical learning of the shape transitions. Spatial configurations (e.g., the layout of objects in a room) contain regularities in the relative positions of objects (e.g., a lamp appears next to the sofa), and learning of such regularities may facilitate visual search and spatial navigation. SL of spatial configurations in vision is tested by showing grids of multiple shapes that, without observers’ knowledge, have been constructed from shape pairs (if one member of a pair appears on the grid, its associate also appears in a fixed relation; e.g., to its left). Since many shapes appear in each grid, pairs can only be learned by extracting probabilities. After brief exposure to the grids, familiarity is higher for pairs than for recombinations of the same shapes into new arrangements, providing evidence of SL. SL is ubiquitous in perception, occurring: (1) in auditory, visual, and tactile modalities; (2) for a range of statistics, including frequency and conditional probability; (3) throughout human development; (4) in other species, such as rats and monkeys; and (5) for many stimuli, from lower-level features to higher-level objects, scenes, and actions. The broad scope of SL suggests that it is a core cognitive function. Important Scientific Research and Open Questions Beyond demonstrating the scope of SL, research has begun uncovering the underlying nature of this process. For example, SL can occur without conscious intent or awareness, but is constrained by selective attention; SL involves memory systems linked to other types of implicit learning, such as artificial grammar learning and motor sequence learning; and SL happens quickly, after only a handful of repetitions of a regularity. This is a relatively nascent field of research, and thus three areas of active study are highlighted here. First, while initial studies of SL used a single set of auditory or visual regularities, the environment contains multiple concurrent sets of regularities. For example, words in multiple languages, or the layouts of different cities. At a more basic level, sensory information arrives at the same time from multiple modalities (e.g., faces and voices), and about different feature types within the same modality (e.g., shape and color). It is important to assess how SL copes with this complexity to determine whether it is suited to more ecological settings outside of the laboratory. Studies have examined SL of regularities appearing simultaneously in different modalities or features, finding that if modalities/features are correlated (e.g., shapes appear in reliable colors) SL proceeds over multi-modal/multi-feature objects. In addition to appearing simultaneously, regularities can also appear sequentially, such as when learning a second language after already knowing a first. When presented with a speech stream constructed from one set of threesyllable words, followed immediately by a second stream constructed from a recombination of the same syllables into new words, learning occurs only for the first language (Gebhart et al. 2009) – in essence, SL of one set of regularities blocks learning of a second set. When two languages are separated in time by a pause, learning occurs for both languages. This raises an interesting possibility that only one set of regularities can be learned in a given “context,” but that pauses and other contextual shifts may allow SL to restart. What counts as a context, and how much evidence about new regularities is required to overcome previously acquired knowledge remain open questions. Second, most studies of SL test learning with the exact same regularities that were trained. For example, if presented with a triplet of shapes ABC during the initial learning phase, the test phase would examine familiarity for ABC. Without making changes between learning and test, it is unclear what has actually been learned. On one hand, SL could be very specific, resulting in knowledge that A is followed 1 s later by Statistical Learning Theory B and then 1 s later by C. Alternatively, SL could be more abstract, resulting in knowledge that A, B, and C “belong together.” These possibilities can be tested using transfer logic: if regularities can be recognized despite a change between learning and test, then the changed aspect is not an important part of what has been learned. Some changes do not matter: SL readily transfers to new temporal orders (training on ABC, testing on CBA), and even after the removal of all temporal information (training on ABC presented sequentially, testing on ABC presented simultaneously), suggesting that SL produces abstract knowledge that generalizes flexibly (Turk-Browne and Scholl 2009). Other changes do matter: after training on large spatial groups (shape triplets or quadruplets), SL does not transfer to the embedded subcomponents (constituent shape pairs), suggesting that SL of spatial configurations operates hierarchically at the largest spatial scale (Orbán et al. 2008). Characterizing what is learned during auditory SL remains an open and important question. For example, the transfer of visual SL to new temporal orders would be disastrous for word learning – reversing the syllables in any word changes its meaning, and most often produces a nonsense word. Third, what purpose does SL serve beyond increasing familiarity? For auditory perception, segmentation of otherwise fluent speech during language acquisition could be a valuable consequence of SL. Segmentation is also important in visual perception, both for extracting edges, surfaces, and objects from the background, and for finding boundaries between events and actions – and again SL may be helpful. Another fundamental consequence of SL for perception is that the brain can use knowledge about regularities to anticipate what will appear next in the environment, allowing for more efficient processing when the predicted sensory information arrives. Objects that reliably predict what will appear next in a temporal sequence activate the anterior hippocampus and prime regions of visual cortex that are selective for the category of the predicted object. For example, faces that are predictive of scenes elicit anticipatory activity in scene-selective parahippocampal cortex (TurkBrowne et al. 2010). While the hippocampus is involved in explicit types of future-oriented behavior, such as planning and prospection, and category- S 3185 selective visual regions are activated by effortful imagery, SL occurs without conscious awareness and thus triggers implicit perceptual anticipation. What consequences SL has for other cognitive processes, such as attention and working memory, remains an open and actively studied question. In sum, there are reciprocal interactions between SL and perception: SL occurs incidentally as a result of perception; in turn, learned regularities facilitate perception by allowing the brain to anticipate the future.

Statistical Learning Theory ▶ PAC Learning S 3186 S Statistical Learning Theory and Induction Statistical Learning Theory and Induction GILBERT HARMAN1, SANJEEV KULKARNI2 1 Department of Philosophy, Princeton University, Princeton, NJ, USA 2 Department of Electrical Engineering, Princeton University, Princeton, NJ, USA Synonyms Nondeductive reasoning; Pattern classification; Pattern recognition; Supervised learning Definition Induction is here taken to be a kind of reasoning from premises that may not guarantee the truth of the conclusion drawn from those premises. It is to be distinguished from “mathematical induction” which is a kind of deductive reasoning. The philosophical problem of induction is whether and how inductive reasoning can be justified. Statistical learning theory (SLT) is a mathematical theory of a certain type of inductive reasoning involving learning from examples. SLT makes relatively minimal assumptions about an assumed background probability distribution responsible for connections between features of examples and their correct classification, the probability that particular examples will occur, etc. The theory seeks to describe various learning methods and say how well they can be expected to do at producing rules with minimum expected error on new cases. Among the topics discussed in statistical learning theory are various nearest neighbor rules, related kernel rules, feed-forward neural networks, empirical risk minimization as a kind of inductive generalization, ways of balancing data-coverage against “simplicity,” PAC learning, support vector machines, and boosting. Theoretical Background A valid deductive argument has a kind of conditional reliability: The conclusion is guaranteed to be true if the premises are true. Inductive reasoning typically lacks such a guarantee. The philosophical “problem of induction” asks whether any sort of justification is possible for inductive reasoning. Clearly there cannot be a deductive demonstration that inductive reasoning has the same sort of conditional reliability as deduction, because then there would be no difference between induction and deduction. But there clearly is a difference. It might be argued that induction is justified because it works. How do we know it works? Because it has worked in the past – not always, but much of the time? It will be objected that this sort of justification appeals to induction and is therefore circular. (Similarly, a deductive justification of deduction would be circular.) But maybe it is possible to give some sort of deductive justification of induction. Of course, nothing can be deduced about induction in the absence of substantive assumptions. So the only serious philosophical problem of induction asks what sorts of assumptions yield interesting conclusions. SLT offers a kind of deductive answer to the problem of induction by characterizing various kinds of induction and then deriving theorems about these versions. While basic results in SLT theory go back to the 1960s, this continues to be an active area and further research is ongoing (e.g., see, Devroye et al. 1996; Vapnik 2000; Hastie et al. 2009; and references therein). In addition to offering a response to the philosophical problem, SLT has many practical applications. SLT applies to inductive pattern recognition, function estimation, as well as other inductive issues. We concentrate here on pattern recognition, which involves using data in order to learn to classify examples on the basis of their features. We also suppose for simplicity that the relevant classification is YES/NO: Is this character an “e”? Does this picture show a face? The data consist in a set of labeled examples. Each example has a set of its features and a label giving the correct classification of the example. In one basic case, it is also assumed that there is a single background statistical probability distribution that characterizes the probabilities that particular instances will arise and the probabilistic relations between features and correct classifications. Furthermore, it is assumed that the same probability distribution is responsible both for the data and for new cases that arise. Minimal assumptions are made about this probability distribution; for example, in the basic case it might be assumed that the instances are independent and identically distributed. Given the unknown probability distribution as the background for a pattern recognition problem, there is Statistical Learning Theory and Induction a minimum expected error R for rules associating labels with features. (A rule with this minimum expected error rate R is called a Bayes Rule.) It follows immediately that induction cannot arrive at a rule with a smaller expected error than R and the question is then how close can one or another inductive rule come to that minimal error rate. Items are assumed to have some number d of features, each of which can take several, perhaps infinitely many, values. We can identify the possible values of features with real numbers. Then to specify the values of all the relevant features of a particular item is to specify a point in a d-dimensional feature space. A simple classification rule is the l-nearest neighbor rule. Given n labeled examples, the rule assigns to any new instance the same label as the nearest labeled example. There are also k-nearest neighbor rules which assign to any new instance the label that a majority of the k-nearest neighbors have (assuming k is an odd number). And there are kn-nearest neighbor rules, where the number of nearest neighbors considered is a function of n. It can be shown that no matter what the background probability distribution, the limit of the expected error of the 1-nearest rule as n ! 1 is no more than 2R . And, it can be shown that the expected error of a kn-nearest neighbor rule approaches R as n ! 1 if kn ! 1 and kn/n ! 0 as n ! 1, no matter what the background probability distribution. So that rule is said to be universally consistent. However, there is not uniform convergence to R , since there will be probability distributions for which convergence is arbitrarily slow. Here we have two interesting results about this sort of inductive method. A different method of reasoning, which philosophers sometimes call enumerative induction, starts with the selection of a class C of rules and chooses from C a rule with minimum error on the data. (This learning method is also called empirical risk minimization.) Vapnik and Chervonenkis (1968) prove that (subject to mild measurability conditions) if and only if the rules in C satisfy a certain condition, namely that they have finite VC dimension (which we explain in a moment), then with probability approaching 1 the expected error of the rules endorsed by enumerative induction will converge uniformly to the minimum expected error of rules in C. In other words if, and only if, the VC dimension of C is finite, this sort of S enumerative induction satisfies the PAC (probably approximately correct) criterion. The VC dimension of the collection of rules C is the largest number N such that some set of N points in feature space is shattered by rules in C, so that for any possible labeling of those N points, some rule in C fits perfectly the points so labeled. If for any finite number N there exists some set of N points that is shattered by the rules C, then the VC dimension of C is infinite. Subject to some mild measurability conditions on the rules in C, enumerative induction is an instance of PAC learning if and only if the VC dimension of rules in C is finite. Learning using standard feed-forward artificial neural networks satisfies the PAC criterion, since the rules representable by such a network with fixed architecture and variable weights have finite VC dimension. A different inductive learning method, sometimes called structural risk minimization balances empirical adequacy of the data against some other feature of rules in C, sometimes mistakenly identified with simplicity. Let C ¼ C1 [ C2 [    Cn [    , where Ci 2 Ciþ1 , where the VC dimension of each Ci is finite and the VC dimension of C is infinite. A particular version of structural risk minimization selects a rule r in C that minimizes a function f(e, i) of the error e on the data and the least i such that r is in Ci. Something like this fits much scientific practice but cannot satisfy the PAC criterion (since the VC dimension of the rules C is infinite). Under certain conditions it does allow universal consistency. So, SLT sheds light on a variety of inductive methods by specifying various assumption different kinds and proving that particular inductive methods have different desirable properties under the appropriate assumptions. This is discussed further in Harman and Kulkarni (2007). Important Scientific Research and Open Questions The field of statistical learning theory is quite active. Some fairly recent developments include support vector machines (Vapnik 2006) and Boosting (Schapire 1999). There are many extensions and generalizations of the basic results in which the different assumptions of the theory are relaxed, stronger results are obtained, more detailed analysis is provided, or different settings are considered. 3187 S 3188 S Statistical Models for Longitudinal Data Cross-References ▶ Bayesian Learning ▶ Connectionist Theories of Learning ▶ Learning in Artificial Neural Networks ▶ PAC Learning ▶ Probability Theory in Machine Learning References Devroye, L., Györfi, L., & Lugosi, G.

Statistical Models for Longitudinal Data ▶ Measurement of Change in Learning Steiner, Rudolf (1861–1925) JENNIFER M. GIDLEY Global Cities Research Institute, RMIT University, Melbourne, VIC, Australia Life Dates Rudolf Steiner was born in Kraljevec, Austria-Hungary (currently Croatia) on February 27, 1861, of Austrian parents. A quiet, introverted child, he spent most of his childhood and youth in a beautiful mountainous region of Austria, surrounded by natural beauty but immersed in the new technologies of telegraph and railway through his father. He attended high school in Wiener-Neustadt, near Vienna. In addition to his school subjects Steiner privately studied high-level mathematics and physics, Ancient Greek and Latin, and the scientific and philosophical works of the major German idealists and Romantics. Between 1879 and 1883, he completed his undergraduate studies at the Vienna Institute of Technology, during which time he worked as a private tutor and editor. In 1891, he completed his Doctorate at Rostock University, Germany, on Truth and Knowledge: The Fundamentals of a Theory of Cognition with Special Reference to Fichte’s Scientific Teaching. While still an undergraduate student, Steiner commenced his in-depth studies of the scientific works of Goethe. Influenced by his exposure to what he referred to as the living thinking of Goethe, Steiner developed a new epistemology in his first authored book Theory of Knowledge Implicit in Goethe’s World Conception, published in 1886. In 1893, he published what is perhaps his most significant philosophical treatise The Philosophy of Freedom. He worked extensively from the age of 21, editing numerous volumes of Goethe’s works between 1882 and 1897, spending the last 7 years of this period working at the Schiller-Goethe Archives in Weimar (Steiner 1925/ 1928). Steiner’s productivity during this time in Weimar was prodigious. In addition to editing Goethe’s work, he put in order the archives of Friedrich Nietzsche at the request of Nietzsche’s sister, edited and published the complete works of Schopenhauer in 12 volumes, and the works of Jean Paul in eight volumes, researched and published some of his most fundamental philosophical works. In 1897, Steiner moved to Berlin, which was to become his base until 1913, just before the outbreak of World War I. In Berlin, Steiner combined his editing work with his own writing and lecturing, and also worked as an instructor at the Berlin “Workers’ School of Education.” As editor of the weekly Das Magazin für Litteratur Steiner came into close social contact with the intellectual and artistic élite of Berlin at the time, his acquaintances including poets, playwrights, novelists, and political activists. In 1900, he began what has become known as his anthroposophical work, which he continued until his death. In 1902 he met Marie von Sievers who would become his constant collaborator and eventually his second wife. During this time he Steiner, Rudolf (1861–1925) worked in collaboration with the Theosophic Society, including becoming the General Secretary of the German Theosophic Society. However, as a result of fundamental differences of direction, he publicly distanced himself from the Theosophic Society in 1913 and moved to Dornach in Switzerland to commence the building of the first Goetheanum. The building was tragically burned to the ground by an arsonist in 1922 shortly after its completion. Steiner almost immediately announced plans for a second Goetheanum, built of concrete, which still stands today in Dornach. Both buildings are considered architectural landmarks of the twentieth century. Steiner’s writing is generally regarded to have occurred in two major phases. In the first phase until approximately 1904, he primarily wrote from a purely philosophical or natural scientific perspective. In the second phase, he claimed to be speaking and writing from his intuitive spiritual-scientific research. He spent much of his adult life traveling and lecturing extensively throughout Europe. From 1888 to 1924 he gave over 5,000 lectures on a wide variety of themes in 96 European cities within 17 countries. His lecturing took him the length and breadth of Europe mostly by train, from Oslo, Stockholm and Helsinki in the north to Milan, Bologna, and Trieste in the south; from Oxford, Torquay, and Paris in the west to Vienna, Prague, and Budapest in the east. In the last few years before his death he gave an average of 400 lectures per year. Steiner died at age 64, after a 6-month illness, on March 30, 1925. Contribution(s) to the Field of Learning In the mode of a “Renaissance universal man” Steiner was a respected and well-published scientific, literary, and philosophical scholar and artist, as well as an accomplished linguist, classical scholar, mathematician, and historian (McDermott 2009). Also a futurist, he had a macrocosmic perspective on time in relation to the evolution of human culture and consciousness. His ideas were post-conventional, innovative, and futures oriented. With foresight he initiated many significant cultural and social projects, which are still active throughout the world 100 years later – including innovative and holistic approaches to education, agriculture (biodynamics), architecture, medicine, social reform, community development, and the arts. He authored over two dozen books, including essays, S 3189 plays, verse, and autobiography and his collected lectures make up over 300 volumes. His complete corpus covers almost every imaginable theme, including art, history, religion, education, evolution, natural and hermetic sciences, meditative practices, psychology, physiology, social and community development, agriculture, and medicine. On a more personal basis, Steiner remains somewhat enigmatic, having been described as charismatic, yet humble, erudite yet matter-of-fact, as an idealist and also pragmatic, as both seriously earnest and extremely funny. Boris Bugayev, a distinguished Russian symbolist poet who wrote under the pen name of Andrei Belyi, wrote a book about Rudolf Steiner in Russian in 1928, noting a more personal feature: " [Steiner] had, as it were, a therapeutic smile; the countenance blossomed. . .one felt that one had nothing of the kind to give in return. He had the gift of the smile, the faculty of direct expression from the heart. . .Many know his sunny smile; we spoke of it. One must speak about it, for not a single photograph of his reflects it. (Cited in (Easton 1980, pp. 215–216)) In spite of his large following, he discouraged any tendency of others to view him as a guru, believing that such a role was no longer appropriate in the modern age when the spirit of individual freedom is vital. Steiner is probably best known in the world today for the independent schooling system that he initiated in the early twentieth century. Steiner founded his first school in 1919, in Stuttgart, Germany for the children of the workers of the Waldorf cigarette factory. Notably, he not only put his educational ideas into practice, he took personal interest in the teachers and the children including apparently knowing every child in the school. He appointed, guided, and advised the first teachers and delivered numerous series of pedagogical lectures. The name Waldorf is still used today for many of the schools, particularly in Germany and the USA. In the UK, Australia, and elsewhere they are more commonly called Steiner schools. The hyphenated term Steiner– Waldorf is becoming increasingly acceptable as an overriding term. As of 2010 there were approximately 1,000 Steiner–Waldorf schools across 60 countries, even more kindergartens and dozens of institutions for special education worldwide. The most extensive concentrations of the schools, and also many teacher education courses and colleges, are in Western Europe, North America, and Australia/New Zealand. S 3190 S Steiner, Rudolf (1861–1925) It is beyond the scope of this brief biography to discuss Steiner–Waldorf education in any detail. However, it should be noted that many of the key features of Steiner pedagogy are to be found in the emerging innovative pedagogies of the late twentieth century and early twenty-first century. These include the importance of integration, imagination, aesthetics, the whole child, ecology, spirituality to name a few. The unique architecture of Steiner–Waldorf schools reflects the striving to create a fully integrated learning environment. While some commentators claim that Steiner’s pedagogical work was ahead of its time, a contrasting view is that Steiner pedagogy was actually very much a product of his time and was closely aligned to what emerged in 1919 as the New Education in Germany after World War I. The substance of much of the critique of Steiner education involves the perceived rigidity of application of Steiner pedagogy in contemporary Steiner–Waldorf schools. While this is actually a critique of the contemporary application of Steiner’s pedagogy rather than a critique of Steiner’s actual ideas, the two are often conflated. On the other hand, there is emerging support for Steiner pedagogy today, particularly from holistic and integral educators (Gidley 2007). Important Scientific Research and Open Questions The primary terms Steiner used to refer to his work were spiritual science and anthroposophy. The term anthroposophy – coined in the seventeenth century by Rosicrucian, Thomas Vaughan – is derived from the Greek anthropos, meaning human being, and sophia, meaning wisdom. In Steiner’s own words in Anthroposophical Leading Thoughts: “Anthroposophy is a path of knowledge, to guide the Spiritual in the human being to the Spiritual in the universe.” The world movement that has arisen from Steiner’s anthroposophy is based on the notion that there is a spiritual world comprehensible to pure thought but accessible only through advanced cognitive faculties. In addition to the educational institutions, numerous medical clinics, therapeutic facilities, banking institutions, and hundreds of farms in many parts of the world bear witness to the wide dissemination and establishment of Steiner’s ideas. Through his biodynamic farming methods, he anticipated the growth of organic farming, believing that a farm should be a selfcontained ecological entity. He was also instrumental in the founding of Weleda, which is still producing homeopathic and herbal medicines today. Steiner’s aesthetic approach inspired artists such as Piet Mondrian, Wassily Kandinsky, and Joseph Beuys. He is also regarded as one of the founders of “organic architecture.” One of the most striking issues surrounding Steiner’s prolific – albeit heterodox – contribution to so many fields of knowledge in the early twentieth century is not that there is a discourse of academic critique but rather that there has been such a lack of response to his work, other than from proponents of Steiner’s approach. Steiner is frequently referred to as one of the most underappreciated figures of the twentieth century (Lachman 2007). Although proponents of Steiner’s work have written a great deal of material about it, the majority has been published by “in-house” Steiner Presses, with much of this being unrealistically uncritical. Steiner’s integralism and his opposition to materialism and the dry intellectualism of modernity led to attacks from upholders of the status quo. One reason given for Steiner’s rejection by the mainstream academy in his time is that as a forerunner of the contemporary holistic/integral movement he was decades ahead of his time. Another stated reason why Steiner’s work was marginalized by the academy is his unashamed esotericism. Critics of Steiner often focus on the fact that he was a spiritual researcher and because of his early association with the Theosophical Society, link his work with the occultism of theosophists. Owen Barfield proposed that it may have been Steiner’s use of the term occult – in the title of one of his principal source books – that has played a great part in his rejection by the academy. Barfield, cited in Reilly (1971/2006) argued, however, that an objective scholarly approach to Steiner’s work would demonstrate that the word occult, as used by Steiner, “signifies no more than what a more conventionally phrased cosmogony would determine as ‘nonphenomenal,’ ‘noumenal,’ ‘transcendental.’” Barfield contrasted this with the more mystical, trance-like Theosophic form of occultism, which Steiner eschewed. According to Steiner himself, in his autobiography, even as an 8-year-old child he was aware of the existence of a supersensible world which to him was just as real as the physical, but his interest as an adult was to further develop such perceptions, consciously through intense, metacognitive activity. Steiner’s signature contribution to this field of study was to apply the rigorous Stimulus–Reinforcer Interaction thinking and methods of the natural sciences to thinking itself, referring to this process as “sense-free thinking.” This formed the basis of much of his methodical research of psychological and spiritual phenomena. There have been several challenges to adequate reception of Steiner’s work in the wider academic world. Firstly, his writings were originally written or delivered in German and many of them have still not been translated into English. Secondly, although Steiner did write a substantial number of actual authored books, the vast majority of his available work is actually based on shorthand transcripts of his lectures, many of which he never had time to revise. Thirdly, his works are so extensive and interrelated that an extraordinary amount of time and effort is required even to access them, let alone comprehend them. Although Steiner’s stated aim was to bring spiritual–scientific research out from the forum of secret societies and place it firmly on the footing of rational and scientific thinking, his achievements fell short of what he apparently hoped for. Ironically, much of his lecturing was enacted outside the academy in private circles of students or in the public sphere. Arguably, he did not manage to make a successful bridge between his spiritual–scientific research and the academy during his lifetime. A challenge for the future for those academics and educators who see untapped potential in his work is to demythologize his body of work and disseminate it in a more scholarly fashion. In summary, in spite of the relative ignorance of Steiner’s writing in most fields of academic discourse to which his work could contribute, he made a seminal contribution to pedagogical theory and practice as well as many other fields. Unlike most spiritual researchers and spiritually oriented philosophers, Steiner never lost sight of the relationship between his spiritual research and its application to the life-world.

A stochastic process is a process which develops dependent on time and in accordance with probabilistic principles. This means that future behavior cannot be predicted with certainty but rather only probabilities as to various possible states for the future. Stochastic models of learning are based on appropriate mathematical models and are constructed to assess and predict states of learning processes accordingly. Theoretical Background Bartholomew’s (1967) seminal work on stochastic processes provides the theoretical foundation for stochastic models of learning. In a metaphorical sense, a learning process is considered to be comparable to the growth of different generations within families and societies. First, a simple mathematical model for the development of a single family line or a learning process is considered. The fundamental requirement in such a mathematical model is that the way in which changes occur must be specified. It is assumed that these changes can be characterized by transition probabilities which are dependent on time. pij denotes the probability that the “son” (= second generation of learning) of a “father” (first generation of learning) in class i has been in class j since the system is closed, where k is the number of classes (see Ifenthaler and Seel 2005). k X Pj ¼ 1 j¼1 Stochastic Learning Theory ▶ Naı̈ve Reinforcement Learning Stochastic Models of Learning DIRK IFENTHALER, NORBERT M. SEEL Department of Education, University of Freiburg, Freiburg, Germany Synonyms Probabilistic models; Stochastic process; Transition of learning P denotes the matrix of transition probabilities. If only family lines in which each “father” has exactly one son (a rather unrealistic assumption) are considered, the class history of the family will be a Markov chain. By interpreting the “population of possible learning states” as composed of such family lines we can make inferences about the changing structure of this “population.” However, in practice the requirement that each “father” should have exactly one “son” is not met. As a result some lines become extinct and others branch off. However, in a population whose size remains constant over a period of time, each “father” will have one “son” on average. Supposing that the probability of the initial progenitor of a family line (in the case of learning processes discussed in terms of preconceptions) being in class j at Stochastic Models of Learning time zero is pj(0), the probability of the line being in class j at time T (T = 1, 2, 3, . . .) is pj(T). The probabilities {pj(T)} can be computed recursively from the fact that pi ðT þ 1Þ ¼ k X pi ðTÞpij ð1Þ i¼1 In matrix notation these equations may be written as pðT þ 1Þ ¼ pðTÞP ð2Þ where p(T) = (p1(T), p2(T), . . ., pk(T)). Repeated application results in pðTÞ ¼ pð0ÞPT ð3Þ The elements of p(T) may also be interpreted as the proportion of the population expected to be in each of the various classes at time T. If the original classes of the family lines are known, the vector p(0) represents the initial class structure. The matrix PT plays a fundamental role in the theory of Markov chains. It can be used to obtain the “state” probabilities from Eq. 3, but its elements also have a direct probabilistic interpretation. If we let pij(T) denote (i,j), the element in PT, then Eq. 3 may be written pj ðTÞ ¼ pi ð0Þpij ðTÞ ðj ¼ 1; 2; . . . ; kÞ ð4Þ pij(T) is the probability of a family line going from class i to class j in T generations. The case i = j is of special interest as the probabilities pij(T) can be made the basis of measures of change (Petermann 1978). In the case of social systems, mutual (and even causal) relationships exist. If a characteristic feature is changed, corresponding changes occur in other parts of the system as a consequence. If the relevant changes can be quantitatively assessed, the mutual relationships can be described – at least in principle – with the help of mathematical equations. A system of equations that serves the purpose of describing the system’s behavior is a mathematical model. Its appropriateness is evaluated in accordance with its potential to provide an effective prognosis of the results of changes in the social system described by the model. Furthermore, the appropriateness of the model depends on whether it can be adapted to include relevant past changes of the system or not. S 3193 Important Scientific Research and Open Questions A process which develops dependent on time and in accordance with probabilistic principles is a stochastic process. This means it is not possible to predict with certainty its future behavior but rather only probabilities as to various possible states for the future. Bartholomew (1967) introduced the application of stochastic models for describing social processes, specifically the growth of different generations within families and societies. In this context, Ifenthaler and Seel (2005) considered the progression of mental models to be comparable to the growth of such social processes. Thus, it is assumed that changes in cognitive structures can be characterized by transition probabilities which develop over time (see Ifenthaler and Seel in press). In order to model and analyze the likelihood that one given state of a cognitive structure (e.g., mental model or schemata) will be followed by another, transition probabilities from one state to another are computed. The results can be presented in a transitional probability matrix (see Eq. 5):  P¼ :77 :38 :23 :62  ð5Þ In matrix P, the entries in each row add up to 1. For example, there is a.38 probability that a less elaborated cognitive structure will increase in size or a.23 probability that an elaborated cognitive structure will decrease in size. These transition probabilities can be illustrated by means of a state transition diagram, which is a diagram showing all states and transition probabilities (see Fig. 1). Possible missing arrows .77 .62 .23 +S .38 -S Stochastic Models of Learning. Fig. 1 State transition diagram S 3194 S Stochastic Pi-Calculus indicate zero probability; the density of the arrows indicates the potency of probability. In order to identify which transition probability deviates significantly from its expected values, a z-score is computed to test significance. A z-score larger than 1.96 absolute is then regarded as statistically significant at the.5 level (see Bakeman and Gottman 1997). The above-described stochastic models provide the mathematical basis for precisely computing learningdependent changes in mental models and schemata (Ifenthaler and Seel 2005, in press). There are several examples of how stochastic models of learning can be applied. Such applications demand a formulation of models by means of stochastic concepts (Ifenthaler and Seel 2005, in press): 1. The first function of the model is to provide insight into the phenomenon to be investigated and to contribute to its understanding. This is the activity which is characteristic for a scientist. The investigation starts with the assessment of data for the process and the formulation of a model which typifies the attributes observed in the system. This stage is the phase of model building. The next step is to predict prognoses for the system by means of the model. Following this, the predictions are tested and conclusions are derived from the model. This phase is called model solution. The last phase consists of a comparison of the conclusions with reality in order to determine whether the model needs to be modified. This is the phase of model testing. 2. The second objective of model building is the application of the models with the goal of a prognosis. Scientists involved in social planning, for example, wish to know what is likely to happen as a result of the realization of specific policies. The manager wishes to know in advance about the consequences of different hiring or promoting practices in the organization. A model which adequately describes the behavior of the system facilitates the answering of these questions. 3. Closely related to the problem of prognosis is the planning of social systems and their operation modus. The management of a company, for example, should be structured in a manner which ensures that an adequate number of skilled workers can be employed to carry out the necessary production processes and that these skilled workers are sufficiently experienced to carry out the functions of the organization. Whether it is possible to realize this goal or not depends on an improvement in the company’s performance. It is therefore necessary to evaluate to which degree the competing policies contribute to the achievement of the fixed objectives. However, in the social sciences this is desirable but only rarely possible. To a certain degree the model replaces the natural phenomenon the scientist is studying. It is possible to carry out (thought) experiments in a “world” created in and through a model. If reality can be substantiated by the model, the results of the experiments can be applied to real phenomena. 4. The fourth way in which stochastic models can contribute to social investigations has to do with measurability. At first glance, this seems to contradict the notion that the lack of appropriate measurements prohibits the development of stochastic models. Both assertions are correct, but they must be viewed from different viewpoints.

Stochastic Pi-Calculus ▶ Evolutionary Learning and Stochastic Process Algebra Stories in Psychotherapy Stochastic Process ▶ Stochastic Models of Learning Storage ▶ Psychology of Learning (Overview Article) Stories in Psychotherapy GEORGE W. BURNS Milton H Erickson Institute of Western Australia, Darlington, WA, Australia Synonyms Healing stories; Metaphor therapy; Metaphors; Teaching tales; Therapeutic metaphors; Therapeutic stories Definition Stories are used in psychotherapy as metaphors, or indirect suggestions, to help effectively communicate a therapuetic message that will commonly provide the means or pathways by which a client may resolve their problems. By the time many clients commence therapy, well-meaning people including relatives, friends, and professionals, have often offered them some sound and helpful advice. That this advice has not been accepted or acted on means that any similar approach in therapy is also likely to be met with resistance, and result in a similar unsuccessful outcome. Therapeutic stories can help bypass such resistance, particularly when the therapeutic metaphors are generated by the client, come from the client’s own story, or are built collaboratively with the client (Burns 2001, 2007). In the original Greek, the term metaphor meant “to carry something across” or “to transfer.” In communication it refers to carrying one image or concept across to another. Most dictionaries or textbooks define metaphor as a comparison between two things, based on resemblance or similarity. For Aristotle it meant the act S 3195 of giving a thing a name that belongs to something else, such as by saying, “His vulture eyes followed their every move.” Vulture is imaginative and thus not literal if we are talking about another human being, but it does imply characteristics, images, and meaning not present if the author had simply stated, “His eyes followed their every move.” For this reason, Diomedes described metaphor as the transferring of things and words from their proper signification to an improper similitude – something that was and is done in language and literature for the sake of beauty, necessity, polish, or emphasis. Metaphor is thus a form of language, a means of communication that is expressive, creative, perhaps challenging, and powerful. As therapy is a languagebased process of healing, heavily reliant on the effectiveness of communication between client and therapist, the use of metaphor in therapeutic stories can link with familiar language structures of the client and assist the client’s process of change. Theoretical Background As a species, we have evolved and developed in response to our experiences. Experience has taught us the skills that we need as people and even shaped our physiology in a way that most functionally suits those skills. It has, over the generations, educated us in the most appropriate forms of mental and emotional adaptation. Experience is what facilitates new learning, broadens our understanding, and deepens our knowledge. Basically, the more we experience, the richer, more functional and more enjoyable is life’s journey. Though experience may be first hand, it may also be second hand and this is where teaching tales and healing stories come into the picture. Through them one person can share their learning experiences with another. In this way stories short-circuit the laborious and long-term process of each individual having to learn something anew. Those who have had the experience are able to communicate to others – through their stories – how to face a similar challenge, what tools are needed to deal with the situation, and how they can enjoy the rewards of achievement. Stories and metaphors are thus efficient and meaningful methods for communicating about experience and sharing what we have learnt with others in a manner that will hopefully help make their journey easier and S 3196 S Story-Based Learning Environments more enjoyable. A therapeutic metaphor is, therefore, a story with an express purpose of assisting clients reach their goals in the most effective and efficient way. It as about filling the experiential gap between what is and what can be. Given this, it is little wonder that every culture throughout history has used stories to communicate values, morals and standards, or that the great teachers of history chose stories, parables, and metaphors as their preferred medium of education. Buddha, Jesus, Mohammed, and Lao Tzu did not lecture, but they told stories. They did not quote facts, statistics, or evidencebased data, but related tales of life. Instead of teaching the rhythmic rote learning of times tables, Lord’s prayers or chants, they offered a parable that opened the range of experiences and interpretations available to their followers. Their stories have lived on for as long as two and a half thousand years, and are still retold by their followers. Stories are a means of communicating par excellence: Not only do we learn from them, but we love them. What is surprising is that teaching tales took so long to be recognized for their usefulness in modern day psychotherapy and counseling, and what is not surprising, is the popularity with which they have been incorporated. It is in the work of psychiatrist and hypnotherapist, Milton H. Erickson that we see the origins of systematic, structured, and intentional metaphor stories that were actively employed to create therapeutic gain. Their benefits in the therapeutic field are that they are interactive, teach by attraction, bypass resistance, engage and nurture imagination, elicit a search process, develop problem-solving skills, create outcome possibilities, and invite independent decision-making. Important Scientific Research and Open Questions There is very little scientific research, let alone good scientific research, into the efficacy of using metaphors as a therapeutic tool. This is in part due to the fact that metaphors tend to be used therapeutically in very individualized ways and are not readily accessible by the standardized, controlled variables desired by empirical research. Much of the “evidence” about the applications and effectiveness of metaphors in therapy therefore comes from case studies. Around four decades ago, Haley recorded and published a broad and comprehensive collection of Erickson’s case studies that included the use of therapeutic stories (Haley 1973). Since then, the literature (professional journals and published books) has reported the application of metaphors in a wide range of therapeutic approaches, including cognitive therapy, counseling, couples therapy, ecopsychology, education, Ericksonian psychotherapy, family therapy, hypnotherapy, Jungian psychotherapy, psychoanalytic psychotherapy, solution-focused therapy, strategic therapy, systems thinking, transactional analysis, and more (Burns 2001, 2005). There has also been a wide variety of clinical problems for which metaphors have been used: abusive relationships, anxiety, asthma education, bulimerexia, cancer, childhood and adolescent problems, depression, divorce, family relationships, pain management, pediatric hospice care, posttrauma stress disorders, somatic complaints, and traumatic memories to name just a few (Burns 2007). Nonetheless, the field is still open to good, innovative research that can help inform practitioners on the effectiveness of using stories in therapy and the variables that are likely to help or hinder that effectiveness.

Story-Based Learning Environments ▶ Narrative-Centered Learning Environments Strategic Learning Strategic Learning ALEXANDER BODEN, BERNHARD NETT, THOMAS VON REKOWSKI, VOLKER WULF Information Systems and New Media, University of Siegen, Siegen, Germany Definition Strategic Learning has been discussed in a variety of fields, foremost in the context of: 1. Individual/Education Strategic Learning can be seen as encompassing strategies for learning on the individual level, aiming at positively affecting the learner’s autonomy. Strategic Learning means learning about learning in order to develop the learner’s full learning potential. 2. Groups/Organizations On the organizational level, Strategic Learning describes learning of organizations about developing the strategic orientation of the organization (usually a company). The strategic orientation of an organization is understood as resembling the knowledge of its members regarding its longterm goals, as well as the strategies and means of how to reach them (i.e., the ability of self-organized work). Theoretical Background Strategic Learning is related to different theories from education and organizational management, dependent on whether the term is understood as learning in a strategic way (educational view), or as learning about strategies (organizational view). Individual/Education The term “Strategic Learning” signifies an educational demand for “learning in a strategic way.” Students are understood as active, self-determined individuals processing information and constructing knowledge (Weinstein 1994). Hence, it is suggested that students need to learn effective strategies for learning, i.e., for reading and understanding texts, or for memorizing codified knowledge in a structured and efficient way (e.g., Simpson and Nist 2000). S 3197 Strategic Learning resembles certain aspects that are covered by various (learning) concepts/theories, such as metacognition or self-regulated learning. Congruent elements that apply to this variety of theories are “self-reflection” or “awareness-creation,” allowing the student to better position her/his learning efforts within her/his general learning objectives, and affording better opportunities to align and to adapt those efforts accordingly. Within this scope, Strategic Learning is seen as a system to help students develop conditional knowledge and reflect it with regard to its practical applicability. In case the (strategic) learning process is triggered by external input, such as by a (strategic) teacher, it can be seen subordinate to ▶ cognitive instruction theories in general. Related questions like “what,” “how,” and “when” to learn, being aware of different types of content knowledge and mediating strategies of learning/teaching, can be seen as elements of ▶ Strategic Teaching. In this sense, Strategic Learning can be regarded as successful outcome of Strategic Teaching. Groups/Organizations Strategic Learning on a group/organizational level can be understood as learning about the underlying strategic orientations of the group or organization, e.g., in a military or business context. As goals and strategies themselves are subject of Strategic Learning, the concept is related to a meta-level, this is: strategic selfdevelopment. In this regard, Strategic Learning is sometimes focused on the level of superior executives who are in charge of leveraging Strategic Learning in their organizations, and of sharing and institutionalizing their knowledge on the corporate level. To some extent, Strategic Learning resembles the conception of double-loop learning in the sense of Argyris et al. (1985). In their view, learning can be achieved when members of an organization compare the (unexpected) outcomes of their actions with the expectations and theories that guided their planning. In this regard, learning entails two different layers which need to be covered: single-loop learning refers to the operational level (“Are we doing things right?”), while double-loop learning comprises learning on the strategic level (“Are we doing the right things?”). In this sense, Strategic Learning is related to learning beyond mere efficiency (“knowing how” to reach an aim), but S 3198 S Strategic Memory is a creative way to question basic assumptions in order to optimize the very strategies of a company, not only their application. As Strategic Learning entails learning that is related to the aims of the company, it attempts to improve the abilities of self-organization of the staff. Hence, it cannot be understood merely in the way of ▶ instructionism, but aims at improving the abilities of the staff to take strategic decisions that develop the strategic orientation of the company. Important Scientific Research and Open Questions Corresponding to the great variety of fields that Strategic Learning is related to, we find a great diversity of “learners” trying to adapt (to) emerging circumstances in their specific field. How such a diversity of learners is able to cope with, and can be efficiently supported in their Strategic Learning efforts, still bears important research issues. Recent research on Strategic Learning formulates a “[. . .] dilemma that currently exists within the paradigm of strategic learning: the dilemma of whether a strategy should be seen as an action dependent on the specific knowledge of an educational actor – strategic knowledge – or whether it is dependent on a planned instructional context – strategic context” (Monero 2007). On the group/organizational level, there is a discourse on whether and how companies can codify, exchange, and institutionalize strategic knowledge (Kuwada 1998), especially with regard to dealing with tacit knowledge of workers. On a general level, there are discussions on how companies can leverage Strategic Learning in practice. As far as practical questions are concerned, related research questions are focused on how Strategic Learning can be organized, e.g., if it can or should be formalized, and how the results can be institutionalized in practice. In this regard, there is a discussion whether Strategic Learning can better be supported by external advisors, or by internal members of the organization. The question whether it is more beneficial to involve “external gatherers to collect very deep and complex content” (Thomas et al. 2001), or rather to rely on “internal organizational members to maximize the understanding of local content and ambiguity” (Kuwada 1998), is a major issue for further research. In so far external advisors are involved, the discourse on Strategic Learning also relates to ▶ Action Research approaches (such as Cooperative Method Development or Business Ethnography). Strategic Learning also relates to the area of design, e.g., in the context of software development. For designers, Strategic Learning appears as an explorative potential of users to self-develop their media competences. To make design supportive for Strategic Learning is to increase learnability, and, therefore, the usability of software products. Hence, for e-Learning systems dedicated to explorative learning, designing for Strategic Learning is crucial, but there is still an ongoing debate on how this can be achieved.

WWW contains a set of protocols to transmit different types of information. Hypertext transfer protocol (HTTP) is the set of rules for transporting information (text, graphic images, sound, video, and other multimedia files) on the World Wide Web. Streaming media content can be transported using HTTP or other proprietary protocols. Such transported content can be viewed using a streaming media player. However the speed and the quality of streaming media content depend upon the Internet bandwidth. In the context of the Internet, bandwidth is defined as the maximum amount of information that can be transmitted over the Internet per second. It is measured in bits per second.

MANIAR School of Creative Technologies, University of Portsmouth, Portsmouth, UK ● Synonyms Broadcast; Multimedia; Streaming; Video Definition The word “streaming media” refers to the technology that allows the continuous flow of multimedia over the Internet. Video is a type of multimedia which combines both visual and audible components. Streaming media in higher education refers to the real-time delivery of audio/video over the networks. ● ● Theoretical Background In computer science, network is a group of two or more computers linked together. A connected group of networks is called Internet. One way of accessing shared and delivered via Internet ease the problem of distributing video-based learning content compared with other media storage format such as tape, CD, and DVD, which have to be physically borrowed from content distributors. Streaming media technology offers instant global delivery of learning content, i.e., students can access learning content anytime, anywhere. Use of streaming media enables lecturers to search, play, and embed streaming media content within any virtual learning environment (Maniar and Bennett 2007) Streaming media technology allows institutions to broadcast live events such as lectures, seminars, workshops, and other education-related content. Use of this technology gives opportunity to synchronize virtual learning environment into live event (Maniar and Bennett 2007) Streamable videos can easily be segmented by adding bookmarks in real time using appropriate tools, which enables teachers to breakdown full length video content into small chunks, with a personalized title and description (Maniar and Bennett 2007) Along with bookmarking, streaming media technology enables a simultaneous synchronization of events such as Powerpoint slides, lecture notes, captions, URLs, comments, discussions, etc. (Maniar and Bennett 2007). S 3200 S Streaming Media ● Delivery of streaming media content can be protected using technologies such as digital rights management (Maniar 2007), which helps to track and protect the delivery of learning content over the Internet Streaming Media Application Protocols media using the Adobe Flash Player software. The RTMP default port number is 1935. TCP and UDP delivery method is used in conjunction with streaming media application protocols to deliver streaming media. RTSP, MMS, and RTMP can be used in conjunction with either UDP or TCP, while HTTP streaming only supports TCP at this time. Streaming Media Method HTTP Streaming HTTP streaming is a mechanism for sending data from a Web server to a Web browser in response to an event. HTTP streaming includes the delivery of market data distribution (stock tickers), live chat/messaging systems, online betting and gaming, sport results, monitoring consoles, and sensor network monitoring. It uses ▶ TCP (transmission control protocol) rather than ▶ UDP (user datagram protocol), since reliability is critical for Web pages with text. HTTP protocol usually uses ▶ port number80 or 8080. However, HTTP streaming is not a preferred delivery protocol for streaming video-based content. Following are the three methods which can be used with the above-mentioned transmission types to deliver streaming media over Internet. On Demand On-demand streaming provides “anytime” access to a prerecorded content. In this scenario, each user can independently request access to the stored content via the Internet. Each user has full control over the content playback, i.e., rewind, pause, fast-forward, and stop. This is because ▶ unicast on-demand publishing points provide a unique data path for every client that requests content. Real-Time Streaming Protocol (RTSP) Live RTSP was developed by the Multiparty Multimedia Session Control Working Group to establish and control media sessions between end points. Clients of media servers issue VCR-like commands, such as play and pause, to facilitate real-time control of playback of media files from the server (Quicktime.com 2010). Most streaming servers use the real-time transport protocol (RTP) for media stream delivery; however some vendors implement proprietary transport protocols. The RTSP default port number is 554. Live events such as lectures, seminars, conferences, and tutorials can be streamed over the Internet with the help of streaming media server live broadcasting software. Microsoft Media Services (MMS) MMS is a proprietary transport protocol developed by Microsoft that is primarily used with Microsoft Windows Media Server to transport media stream over the Internet to the Windows Media Player (Microsoft.com 2010). The MMS default port number is 1755. Real-Time Messaging Protocol (RTMP) RTMP is a proprietary transfer protocol developed by Adobe Systems (formerly developed by Macromedia) that is primarily used with Adobe Flash Media Server to transport media stream over the Internet on students’ computers (Adobe.com 2010). Students’ can play flash Simulated Live Streaming media server can simulate live broadcasts by creating playlists of prerecorded media files. As with live broadcasts, all users connecting to the stream see the same point in the simulated live broadcast at the same time, which creates a simulation of watching a live event. Since the event actually is not live, broadcasting software is not required. Streaming Media Server Software A few examples of industry standard streaming media servers are given in Table 1.

It is called high definition (HD) streaming. HD streaming requires a stable and uninterrupted Internet connection speed of around 4 mbps or more. A server and a client’s computer which support HD streaming are essential in order to experience HD streaming. How long it will take for HD streaming to be a standard streaming medium is a debatable question. Secure delivery of audio-video streams has made this technology very attractive for content distributors. 3201 Streaming Media.

These word roots carry the meaning of restriction and limitedness and reflect individual psychosomatic states under physical pressure or mental demands. In the 1930s, researchers in physiology and psychology, such as Walter Cannon and Hans Selye, developed the concept of stress in line with the proliferation of behavioral approaches that focus on the framework of stimulus–response (S-R) processes. For instance, Walter Cannon considered stress as the fight-or-flight reaction that could cause certain disturbances of homeostasis (i.e., the maintenance of coordinated, balanced physiological states of an organism). Hans Selye further proposed and attempted to differentiate two related terms: (1) stressors, representing any pleasant (e.g., attending an academic achievement award ceremony) or unpleasant (failure in a high-stake examination) demands that are imposed upon the individual, and (2) stress, designating nonspecific consequences of any demands upon the body (e.g., fast heart beating and insomnia due to the excitement or frustration). According to this notion, regardless of the nature of stressors, an organism may display a three-stage general adaptation syndrome, namely, the alarm reaction stage, the resistance stage, and the exhaustion stage. This conceptual framework, which triggered a number of behaviorist studies on life events (beginning or ending school, change in schools, etc.), was later challenged and modified by researchers who adopted emerging cognitive perspectives. According to this new Stimulus-Organism-Response (S-O-R) framework, stress is defined as “a particular relationship between the person and the environment that is appraised by the person as taxing or exceeding his or her resources and endangering his or her wellbeing” (Lazarus and Folkman 1984, p. 19). This definition, which is widely accepted by the research community, emphasizes that an encounter is stressful when and only when perceived and cognitively appraised as being threatening to one’s well-being. Learning, on the other hand, is also defined and researched via two major approaches: behaviorist and cognitive. Although systematic empirical research on learning (of new associations) was conducted as early as 1885 by a German psychologist Hermann Ebbinghaus, there has been no single definition used S 3203 by all researchers and educators. In general, learning is regarded as changes in one’s task performance from behaviorist perspectives and viewed as changes in one’s mental representations from cognitive approaches. However, as pointed out by Shuell (1986), both sides appear to have similarities in defining learning in terms of three criteria: (1) a change in a person’s behavior or ability, (2) this change arises as a result of practice and/ or experience, and (3) the change is relatively enduring. Broadly speaking, learning is linked to changes in learners’ behavior, emotion, thoughts, values, and belief system as a result of individual experience. In education and training, learning is often practically considered as the processes of acquisition of new knowledge and skills. In that sense, researchers in information processing assert that learning occurs with the alteration of long-term memory in human cognitive architecture (Low et al. 2009). The relationship between stress and learning is complex and can be identified in the following aspects: (1) learning under stress, (2) impact of learning on stress, and (3) factors that affect both stress and learning. Theoretical Background Learning under stress – Animal and human models have been proposed to depict the effects of stress on learning (see Jöels et al. 2006). Stress tends to activate two psychoneuroendocrine systems, namely, the autonomic nervous system (ANS) and the hypothalamopituitary-adrenal axis (HPA). From an evolutionary perspective, these two essential systems exert a streamlined impact on the organism’s information processing and thus learning. On the one hand, in response to stressful situation, ANS quickly releases catecholamines (adrenaline, noradrenaline, and dopamine) and peptides to enhance short-lasting excitability (i.e., increased synaptic responses and electrical firing of neurons). The consequences are: (1) the performance of working memory is to some extent enhanced (e.g., shortened reaction time), and (2) working memory performance becomes less accurate due to the elevated arousal level. On the other hand, HPA increases the secretion of corticosteroid hormones in response to stress (cortisol in humans, also known as stress hormone). While catecholamines from ANS predominantly alter neural activities immediately after stress, the HPA action mainly occurs with a considerable delay and deploys a longer-lasting effect. S 3204 S Stress and Learning In a threatening situation, the elevated HPA functioning tends to suppress irrelevant information sometime later by raising the threshold for synaptic enhancement of input from other sources. As pointed out by Jöels et al. (2006), the combined ANS and HPA activities “preserve an appropriate priority in the reaction to challenges” (p. 156) and thus form an optimized functioning for learning under stress, and excessive stress can cause hyperactivities of both ANS and HPA and may lead to psychosomatic symptoms (e.g., heart palpitations, hypertension, forgetfulness, and inability to concentrate) and thus impair memory and learning. Impact of learning on stress – From the perspective of evolutionary educational psychology, there are two types of learning: (1) the learning of biologically primary knowledge for which human beings have evolved over millennia to acquire easily, quickly, and automatically, and (2) the learning of biologically secondary knowledge that is only developed and required at the recent, advanced stage of civilization (Low et al. 2009). Biologically primary knowledge, such as listening to and speaking native language or the recognition of facial expressions, is essential for the human species to survive and can be learned without conscious effort simply by immersion into a community. Biologically secondary knowledge, however, is specifically demanded by modern societies and needs to be acquired with great conscious effort and explicit instruction. Most academic knowledge (e.g., in the categories of written language, mathematics, physics, and biology) taught in educational institutions is biologically secondary, and the learning of such knowledge is evolutionarily unprepared, cognitively difficult, and intrinsically stressful. The stressful learning processes for the acquisition of biologically secondary knowledge can be exacerbated by inappropriate instruction and ineffective learning strategies. Factors that affect both stress and learning – In order to include other factors that significantly influence individuals’ stress level and learning outcomes, a broader theoretical framework is needed. Very often, a triangular model that consists of social, physiological, and psychological variables is required to identify complex interrelations among various factors, and appropriate model-building methodology can be employed to evaluate its fit and proximity to real-world processes. For instance, poverty may be considered as an important contributing factor to pupils’ stress and learning. In this case, variables like nutrition, physical health, mental health, study conditions, self-esteem, achievement motivation, and school performance can be included in a representative model and thus their integrations can be examined. Important Scientific Research and Open Questions In line with animal research (mainly using rodents and chickens) in learning sciences and neurobiology, there is a trend that more and more studies on stress and learning have recruited human volunteers. Such studies are often of an interdisciplinary nature and are conducted with methodological rigor, employing instruments with psychometric verifications, physiological equipment, biochemical measures, computerized technology, and true experiments with random assignment (Jöels et al. 2006). It is found that whether stress facilitates or impairs (or has no significant effect on) learning depends on the source of stress, stressor timing, stressor intensity, stressor duration, and learning task. Research in this direction is needed. For instance, Schwabe and Wolf (2010) assessed the impact of learning at the onset of socially evaluated cold pressor test (i.e., subjects were watched by an experimenter of the opposite sex and videotaped during hand immersion into ice water) in healthy young men and women and reported a memory-impairing effect under stress. Various learning conditions can induce stress. As summarized by Low et al. (2009), instructional designs that violate cognitive principles (e.g., split-attention effect, redundancy effect, and modality effect) derived from research on human cognitive architecture tend to increase cognitive demands and can elicit stress in learners. For instance, when learners have gained a certain level of expertise in English as a second language, they found that too many explanatory notes in reading passages were hard to ignore and thus annoying. Such a type of redundancy effect has been replicated in experiments conducted in other domains (Low et al. 2009). Since assessment (including streamlining learners according to their pre-study knowledge levels, measuring learning outcomes, providing feedback to learners, etc.) is an essential part of learning processes and many educational opportunities (as well as life prospects) are associated with the results of high-stake assessment, it is not surprising that tests and examinations are perceived by many learners as one of the most stressful Stress Management experiences (Stöber and Pekrun 2004). Research on test anxiety (sometimes under broader or more specific constructs such as examination stress, performance anxiety, competitive anxiety, maths anxiety, and test emotions) has a long and fruitful history, and reliable scales have been developed and used in different educational settings. Current research in this area is advancing in the following new directions: multidimensionality of test anxiety, learning phases associated with test anxiety, how test anxiety relates to attention and memory, impact of test anxiety on performance, and processes of emotional regulation (see Stöber and Pekrun 2004). In research that attempts to incorporate both stress and learning in a comprehensive framework, there are two noticeable trends. One approach is to adopt an ecological model, such as the impact of social problems, digital or mobile study environments, or parental orientations on stress and learning. The other type of approach is to focus on individual differences and effective personalized interventions, for example, how learning disability influences an individual’s stress level and learning processes and what coping strategies can be used.

S 3205 Stress Management PUTAI JIN School of Education, University of New South Wales, Sydney, NSW, Australia Synonyms Managing stress; Stress reduction; Stress relief; Stress treatment Definition The term “stress management” refers to a fine array of evidence-based techniques together with proactive procedures to handle stress. Earlier research on stress emphasized the negative consequences of stress caused by excessive demands or dramatic encounters, such as the fight-or-flight psychosomatic reactions (Cannon 1929) and general adaptation syndromes (Selye 1936); the aim of many stress management programs has been mainly the reduction of stress effects. However, the current trend is that more and more researchers and stress management program providers are adopting a broader spectrum of both theoretical and practical perspectives to design, test, modify, and implement stress management techniques and procedures, ranging over preventative, reaction-focused, and wellbeing oriented measures. The objectives of effective stress management are in fact not only for the amelioration of psychophysiological reactions to stressors but for the formation of various positive states of prosperity. In other words, stress management has transferred from simply an antidote to unpleasant feelings to part of a holistic, comprehensive regimen or well-being promotion scheme. In this sense, stress management is widely used in individual cases (e.g., a tailored procedure to treat early symptoms of depression), group settings (e.g., family therapy to deal with conflicts between the parents and their teenage child), and organizational contexts (e.g., employee assistance programs to train staff to protect themselves from sexual harassment in the workplace). Theoretical Background There are three major theoretical frameworks that form the foundations of various stress management programs: behavior-focused, cognitively oriented, and S 3206 S Stress Management psychoneuroimmunologically based. The first is behavioral theoretical framework, which emphasizes the stimulus-response patterns. Many stress management programs of this type focus on how to take appropriate actions to control environmental or internal stimuli so that the behaviors that are related to stress can be modified. For instance, in order to quit smoking, one step of the procedure is to remove the ashtray from the living room so that the habitual behavior of smoking can be somehow inhibited. Here, the ashtray acts as an environmental stimulus (a reminder or a convenient knick-knack) for smoking and thus this negative factor ought to be removed in order to foster desired behavioral changes. According to the behavioral model of stress management, the stimuli that lead to certain responses can be from internal channels as well. For instance, one of the anger management practices is to roll one’s tongue and count from one to ten when one feels the rage and is about to lose one’s temper. Here, the awareness of a surge of anger (e.g., trembling hands) serves as an internal stimulus. Theoretically, the temporary delay of this surge may be able to slow down or even stop the acceleration of sympathetic reactions (e.g., increased heart rate and elevated adrenaline secretion for a forthcoming “fight”) to allow the parasympathetic system to kick in so that the homeostasis can be restored (e.g., enabling cardiovascular functioning and catecholamine levels to move back to the balanced, normal state). Therefore, this proactive step may help a person with problems of controlling emotion to reduce the habitual explosion of anger. The second theoretical framework for stress management is derived from cognitive approaches. According to Lazarus and Folkman’s (1984) seminal work, stress is determined by an integral cognitive process of two aspects: (a) how the stressor is continuously appraised by a person, and (b) what the resources and coping skills a person possesses. The appraisal can be primary, secondary, tertiary, and so forth; the resources can be adequate social support actively sought by an individual and the learned coping skills can be appropriate reinterpretation of stressful encounters. During the recent decades, this cognitive appraisal theory has gradually replaced the traditional, seemingly oversimplified stimulus-response theoretical framework. Various problem-focused and emotion-focused stress management programs have been proposed and widely used. In line with the trend of proliferations of interdisciplinary research, a number of researchers have used the psychoneuroimmunological framework in stress management (e.g., Jin 1994). Psychoneuroimmunology emphasizes the complex interactive functioning between psychological, physiological, endocrine, and neuroimmune factors. According to research on the hypothalamo-pituitary-adrenal axis (HPA), both cognitive and emotional disturbances can trigger the release of cortisol and other stress-related hormones in humans, which in turn affect the functioning of cardiovascular, digestive, skeletal-muscular, and immune systems. The elevated level of cortisol can suppress immune functioning and then a weakened immune system may lead to poor health. An effective stress management program, be it a type of cognitive/ emotional training (e.g., meditation), physical exercise (e.g., brisk walking), or a combination of both (e.g., Tai Chi Chuan – a form of Chinese moving meditation), may help clients/trainees reduce the excessive level of stress-related hormones such as cortisol, and consequently the decrease in stress hormones may be beneficial to restore or enhance immune system. This theoretical framework predicts both the short-term and long-term effects of established stress management techniques and associated procedures on mental and physical health. Important Scientific Research and Open Questions Basically, there are two lines of research in stress management: one line of research assesses the efficacy of stress management that uses behavioral change strategies, and the other examines the effectiveness of stress management that employs cognitive restructuring strategies (Smith 1993). Some studies further attempt to evaluate the additive gains from both behavioral training and cognitive treatment (Jin 1994). As summarized by Smith (1993), a number of empirical studies have been conducted to ascertain the utility of stress management with behavioral orientations. On the whole, research has endorsed the usefulness of a large repertoire of relaxation techniques and behavior modification procedures. For instance, Smith (1993) recommended a hierarchy of relaxation techniques (from basic to profound) that are to some extent evidence-based: progressive relaxation ! Yoga stretching ! deep breathing exercises ! autogenic Stress Management “warmth/heaviness” exercises ! autogenic hints targeted to internal organs (lower abdomen, heart, etc.) ! imagery exercises with a simple stimulus ! imagery exercises with unconscious answers ! nonanalytic focusing meditation (counting one’s own breaths, silently chanting a mantra, etc.) ! Zen mindfulness meditation (openness to the flow of all arising stimuli). Research in stress reduction also supports the application of biofeedback, moderate physical exertion, and time management schemes. Cognitive coping strategies and associated models have been tested and refined in empirical studies on stress management (see Smith 1993). Cognitive appraisal training has been identified as the key element of various cognitive restructuring programs, such as cognitive therapy and rational emotive therapy. Typically, those programs help clients identify irrational thinking and test their beliefs against reality through their experience of personal experimentation. The procedures are varied, depending on the nature of the problem, features of the stressful situation, and the client’s personality and previous experiences. Nevertheless, cognitive restructuring processes are more or less in accordance with an A-B-C-D-E paradigm. Specifically, A refers to the activation of experience; B refers to the beliefs that a person currently holds; C refers to the consequences resulted from irrational beliefs; D refers to the client’s effort (with the necessary assistance from the therapist) at disputing irrational beliefs; and E refers to the client’s new experience regarding the effect of successfully challenging and correcting irrational beliefs. The effect can be incremental and thus the whole procedure can be ongoing and spiral. Such cognitive restructuring interventions, in combination with behavioral modification strategies, have been successfully applied in many stress management programs, such as desensitization, assertiveness training, and self-efficacy enhancement. In the learning context, stress management has been implicitly or explicitly learned and practiced – how to deal with pre-exam stress and uncertainty, meet the deadline of an important assignment, get along with peers in a team or class, confront possible campus bullying, adjust oneself in a new learning environment, and so forth. There is growing evidence to demonstrate that students need to be provided with stress management service/training, not merely by a stand-by counseling center but also S by a general education curriculum. For instance, in a recent study aiming to enhance students’ coping with test anxiety, a preventive stress management project comprising lectures and peer coaching was conducted at the University of Würzburg in Germany (Neuderth et al. 2009). These types of early interventions were well received by the participants. Since stress reaction in general includes three stages, namely, alarm, resistance, and exhaustion (Selye 1936; Smith 1993), it will be helpful to design and implement a clientoriented, carefully tailored stress management education program pinpointing relevant cognitive appraisal and coping strategies at different phases of stressful encounters. Because stress management is an emerging research area, it is not surprising that this area contains a variety of research designs and interpretations. Whereas there are excellent studies in the accumulated literature of psychosomatic research and stress management, it is not uncommon for some studies to adopt convenient samples or own-control designs. Since stress management programs, whether prevention-oriented or intervention-oriented, require a considerable amount of resources, methodological rigor should be ensured in order to obtain outcomes that are valid and reliable. Studies on the efficacy of stress management tend to be conclusive if they have employed true experimentation, well-controlled quasi-experimental approach, or survey with representative samples and validated instruments (see Jin 1994). In particular, the placebo effect should be identified or ruled out. Stress management research should also pay more attention to the groups/subpopulations having special needs, such as the elderly, students with learning disabilities, and survivors of natural disasters or traumatic events. In addition, researchers can take advantage of rapidly upgraded information technology by designing interactive multimedia material for the learning of coping skills and using the Web site for stress diagnosis.

Thus, living system and the medium mutually specify each other so that each contributes to creating the world of the next instant, and so on. ▶ Stress Management Stress Relief ▶ Stress Management Stress Treatment ▶ Stress Management Stress-Related Growth ▶ Posttraumatic Growth Structural Components Structural components in the Atkinson–Shiffrin model are places for storing information such as the sensory registers, short-term memory, and long-term memory.

Thus, structural learning can be conceived as an adaptive process that extracts invariants of sensorimotor mappings that are valid for a number of task environments. These invariants can be exploited for adaptation to novel but related tasks and lead to facilitated learning. Such ▶ facilitation is sometimes called ▶ learning-to-learn. Theoretical Background The term “structural learning” has its origins in adaptive control theory (Åström and Wittenmark 1995) and the theory of Bayesian networks (Pearl 1988). Adaptive control is a branch of control theory aimed at problems in which some of the properties of the system that we wish to control are unknown. Conceptually, two levels of “not knowing” can be discerned: we might know the structure of the control task (e.g., the form of the equations of motion governing an object that we wish to manipulate), but not know the setting of the particular parameters of the structure that are currently in play (e.g., the mass of the object). This situation constitutes a parametric adaptive control problem, which consists of simultaneously estimating the unknown parameters and using these parameter estimates in the control process. However, if the structure of the control task itself is unknown, one deals with the much harder problem of structural adaptive control. Such structural learning, in its most general form, needs to develop a suitable representation of the control process by determining the dimensionality and form of the control problem, the functional relationships between the control variables, their range of potential values, and the variability associated with them. Due to the difficulty of the structural learning problem, control theory has primarily focused on the parametric control problem. The problem of structural adaptive control can be illustrated in a simple toy example (Braun et al. 2010). Consider operating a machine with two adjustable dials, each of which controls a single parameter (Fig. 1a). The machine is performing well at a particular task (red setting) and you want to adjust it for a new a b m R1 Parameter 2 Definition 3209 R2 R3 RN --- m P1 P2 Parameter 1 Structural Learning in Sensorimotor Control. Fig. 1 Schematic diagram of structural learning. (a) The task space is defined by two parameters, but for the given task, only certain parameter combinations occur (black line). This relationship is indicated by the curved structure, which can be parameterized by a one-dimensional metaparameter m. However, a parametric learner that is ignorant of the structure has to explore the full two-dimensional space when readjusting the parameter settings. (b) Structural learning in a Bayesian network. The nodes of the network represent random variables such as the N sensory input variables R1 to RN and the two control parameters P1 and P2. Learning the full joint distribution of the network without the hidden meta-parameter m would imply a network structure where all the R-nodes are connected to all the P-nodes. Knowing the structure with the metaparameter m thus simplifies the learning problem substantially, since only this meta-parameter has to be adapted if a novel task with the same structure is encountered (Reprinted from Braun et al. (2009). With permission) task (blue setting). There are two ways of approaching this problem. One solution is to adjust independently both dials, thereby, exploring the full two-dimensional space. However, you might find through experience that for a set of related tasks the correct dial settings are not randomly scattered in the full two-dimensional space, but they have a certain functional relationship that is possibly probabilistic or nonlinear (black line). Such a functional relationship corresponds to a lower dimensional structure in the parameter space and allows building a meta-dial (with setting m) that controls and restricts all other dials to this subspace (Fig. 1a). Such structural learning would speed up the adaptation process considerably, as searching a lowdimensional subspace is always faster than exploring the full-dimensional space. In biological organisms S 3210 S Structural Learning in Sensorimotor Control that are faced with an adaptive control problem, controlling the dials corresponds to controlling internal parameters that determine how sensory inputs are transformed into motor outputs. Discovery of structural relationships could therefore provide a basis for learning-to-learn in biological organisms. In sensorimotor control, facilitation of learning in generalization tasks is a well-known phenomenon (e.g., generalizing from ice skating to rollerblading). While such enhanced learning might not always be the consequence of structural learning (there could also be processes that increase adaptability nonspecifically), it has been shown that random experiences of different sensorimotor tasks that share the same structure lead to structure-specific learning-to-learn effects (Braun et al. 2010). For example, it has been shown that learning a novel rotational mapping between hand movements and cursor movements on a screen (e.g., a rotation angle of 90º means that hand and cursor movements are orthogonal to each other) can be facilitated if many different rotation angles have been experienced before (Braun et al. 2009). Importantly, this facilitation does not occur if many different unstructured random mappings have been experienced before. This suggests that the observed facilitation effects are structure-specific. The term “structural learning” also plays an important role in the theory of Bayesian networks (Pearl 1988). A Bayesian network is a graphical method to represent the joint distribution of a set of random variables (Fig. 1b). The random variables are represented as nodes in the network and could, for example, stand for sensory inputs or motor outputs. The dependencies between these variables are expressed by arrows in the network that indicate the relation between any variable and its direct causal antecedents. These dependencies – that is, the presence or absence of arrows in the network – determine the network structure, while the probabilities that specify the actual strength of the dependencies are the parameters of the structure. Therefore, structural learning refers to learning the topology of a Bayesian network, whereas parametric learning refers to learning the quantitative relationship between the variables given by a structure. The toy example above can also be cast as a Bayesian structure learning problem, where the relationship between the control variables has to be learned. In cognitive science, investigators have employed Bayesian network models extensively to study how humans learn causal structures (Kemp and Tenenbaum 2009). Similarly, hierarchical Bayesian models have also been used to study structural learning of different sensorimotor mappings. Important Scientific Research and Open Questions Structural learning has been shown to play an important role both in sensorimotor control (Braun et al. 2010) and in human cognition (Kemp and Tenenbaum 2009). This raises the question whether and in what ways the two kinds of learning interact or built upon each other. For example, one of the earliest accounts of facilitated transfer between tasks with a similar structure stem from experiments on animal cognition in which monkeys had to learn to categorize novel objects based on a random exposure to similar objects (Harlow 1949). In psychology it has been hypothesized that the animals had formed learning sets. Yet, this facilitation of learning after random exposure can be conceptually recast as a structural learning process. Thus, structural learning might provide a connection between sensorimotor learning and more cognitive forms of learning. Scalable motor structures could also be considered as building blocks of motor concepts or motor schemas. Some of the important open questions with respect to structural learning in sensorimotor control are as follows: What is the minimum experience necessary to induce structural learning? How can structural learning be enhanced? What is the prior expectation over different structures? In neurobiological terms, one of the most important questions is how neural networks can achieve structural learning.

Accordingly, the individual may establish specific individual and pursue learning goals with few or no external boundaries as typical during spontaneous, self-initiated informal learning. Alternatively, the individual may have access only to specific, defined resources to pursue individual learning goals, such as during free-time learning in formal settings. In cases where learning goals are externally established as in most formal school settings, the individual determines how they will be pursued. In essence, the cognitive demands shift from externally mediated selecting, processing, and encoding during directed learning to individually anticipating, seeking, and assessing relevance based on unique needs and goals. Theoretical Background Student Learning Outcomes ▶ Outcomes of Learning Student Modeling ▶ Automated Learning Assessment and Feedback The perspectives of learning and cognition researchers and theorists vary with respect to the underlying assumptions of student-centered learning. To scholars who emphasize externally defined learning outcomes, SCL principles and practices are criticized as lacking empirical foundation and being misguided (see, for example, Clark and Feldon 2005). These criticisms are bolstered by research indicating the need for and effectiveness of explicit guidance over general advice (Kirschner et al. 2006) and the consequences of S 3212 S Student-Centered Learning stimulus overload in loosely or ill-structured learning environments (Mayer et al. 2001). Although these criticisms have compelling face validity, the conclusions have been based largely on externally mediated learning. This, the research assumptions and context bear little similarity to the type or nature of learning advanced by SCL advocates. Perhaps most fundamentally, all learning is not mediated by engineered instruction; instead, individuals learn and interact continually, seeking knowledge, negotiating meaning and understanding and learning within their everyday environments. This is most evident in how and why we access the Internet to identify a wide range of learning resources, including to locate resources for formal school lessons and projects, plan travel, identify activities of interest for children, plan for retirement, shop comparatively online, and a virtually unlimited number of planned and spontaneous learning tasks. Instruction comprises one significant option to promote and support learning, and in many cases it may be the best option, but clearly not the sole or exclusive approach. Hannafin et al. (2009) contrasted basic differences between time-tested cognitive principles supporting externally mediated learning and student-centered learning noting “fundamental shifts in cognitive requirements as well as the foundations and assumptions underlying their design and use” (p. 196). The locus and nature of knowledge, the role of context in learning, and the role of prior experience are central to both externally mediated and student-centered approaches, but the associated assumptions and implications vary considerably. Among externally mediated researchers and theorists, knowledge has been traditionally viewed as existing independent of individuals to be acquired and understood according to canonical conventions, contexts comprise stimulus elements and their proximal relationships, and prior knowledge and experience establishes and reifies strength of association and relationship within complex schemata. In contrast for student-centered learning researchers and theorists, knowledge and meaning does not exist independent from each other but are constructed dynamically by individuals, context and knowledge are inextricably tied and are mutually interdependent, and prior knowledge and experience influence initial beliefs and understanding and must be acknowledged and addressed for learning to become meaningful to the individual. Unlike the time-tested principles underlying externally mediated instruction, the research and theory based underlying SCL is beginning to emerge. Some have suggested that learning demands become increasingly complex since individual “meaning” is influenced more by the diversity between than the singularity across learners. Among advocates, SCL goals have been described as important but elusive. According to Land (2000, pp. 75–76) without effective support, " misperceptions, misinterpretations, or ineffective strategy use. . .can lead to significant misunderstandings that are difficult to detect or repair. . .metacognitive and prior knowledge are needed to ask good questions and to make sense. Cognitive psychologists characterize prior knowledge as schema which represents the organization of, and relationships among, an individual’s network of knowledge and skill. While there is unanimous agreement on the significance of prior knowledge, the locus, nature, and meaning of knowledge are often disputed. Among SCL theorists, understanding and sensemaking are uniquely honed by the individual’s prior knowledge and experience and influence both what is known and how it is known. Initial understandings, including canonically accepted conventions as well as misconceptions, influence the ability to detect, interpret, and synthesize knowledge. In SCL, canonical perspective does not supplant initial conceptions, but rather the learner is guided to challenge initial assumptions as well as to test and refine initial conceptions. Thus, prior knowledge and experience influence the individual’s ability to mediate their own learning – a central assumption of student-centered learning. Explicit guidance can minimize cognitive load demands during instruction by, for example, reducing or eliminating extraneous load while amplifying aspects considered central (germane) to defined goals (Kirschner et al. 2006). Although well documented for directed learning during instruction, student-centered learning emphasizes the individual’s capacity to identify relevant resources and mediate cognitive load. Consequently, explicit guidance is rarely appropriate when the individual determines the learning goal and/or means during SCL. Since neither goals nor means (or both) may be explicitly specified a priori, scaffolding often assumes the form of self-checking, navigation guidance, prompts to reassess and evaluate progress, prompts to reexamine Student-Centered Learning goals and progress, reflection on state of understanding, and support for resetting and refining goals or strategies. Whereas externally directed approaches tend to stimulate processing associated with to-be-learned canonical beliefs, SCL typically focuses on mediating individual’s perceptions and beliefs. Student-centered scaffolding supports the individual’s efforts to identify relevant goals, pursue and monitor efforts toward those goals, and reconcile differences between existing understanding and to-be-learned concepts and constructs. Typical SCL approaches identify initial understanding in order to build from and refine, rather than to impose canonically correct or generally accepted views on, existing beliefs and dispositions. Not surprisingly, among different cognitive styles, field-independent learners who tend to self-organize and work independently perform well in less-structured learning environment, while field-dependent learners often struggle, solicit correct answers rather than ideas and guidance, and become frustrated by the absence of explicit structure and external expectations. To facilitate meaning making and minimize inert knowledge, SCL environments often emphasize authentic experiences or realistic simulations to stimulate interaction. These contexts help students to identify learning goals, formulate and test predictions, and situate understanding within the individual student’s experiences and enable them to understand ordinary practices from a real-world perspective. Important Scientific Research and Open Questions Some have suggested that while SCL has the potential to deepen learning when strategies are followed, the available strategies are unutilized or underutilized. For example, few researchers have documented conclusive evidence for effective metacognition scaffolding during student-centered learning. To be effective during SCL, students need key domain knowledge and the ability to regulate cognition as they formulate and modify plans, reevaluate goals, and monitor individual cognitive efforts. This knowledge and skill is necessary but often insufficient, however, as students often fail to invoke and regulate existing cognitive skills when confronting learning tasks that are too easy or too difficult, where they lack motivation to engage the tasks, or when they perceive a lack of relevance. The situated learning paradox suggests that prior knowledge considered critical during SCL often reflects S incomplete and inaccurate misconceptions (Land 2000). Without adequate background knowledge and support, learners often fail to detect inaccurate information or reject erroneous hypotheses when they encounter contradictory evidence. Rather than building from and refining initial beliefs based in personal experience, the misconceptions are inadvertently reified. Lacking appropriate guidance and support, misinformation and disinformation may go undetected as beliefs associated with misunderstandings are strengthened rather than reconciled. Scaffolding research and theory holds promise for refining the guidance and support provided during SCL. Soft scaffolding, provided dynamically and adaptively by teachers, peers, and other human resources to accommodate real-time changes in needs and cognitive demands, has often proven inconsistent in implementation frequency, quality, and impact on student learning. Similarly, technology-enhanced support (hard scaffolding) has proven effective in learning basic information, but often ineffective in promoting the generalizable reasoning and thinking valued in student-centered learning. Research is needed to study how SCL components are utilized and negotiated individually, meaning is differentiated based on unique needs and goals, and individual needs are (and are not) addressed. Metacognition, the ongoing monitoring of one’s cognitive processes, is among the most important yet also potentially most problematic cognitive construct associated with SCL. Since student-centered learning emphasizes learning in less-structured or illstructured environments, where students regulate their individual learning, the ability to monitor one’s cognitive processes is fundamental to evaluating progress toward meeting individual learning goals and means. Students who have, or develop, metacognitive strategies tend to perform more successfully than those who do not. Thus, research is needed to clarify the extent to which learners must possess initially, require advance training prior to, or can develop the requisite skills needed to monitor their progress during studentcentered learning. Given the cognitive demands associated with student-centered learning, it is important to better understand how, when, and if individuals manage cognitive load. Intrinsic cognitive load reflects the difficulty inherent in the information to be learned, germane cognitive load reflects the effort needed to create 3213 S 3214 S Student-Controlled Instruction relevant schemas and models for future learning, and extraneous cognitive load reflects non-relevant cognitive requirements associated with the instructional materials, method, and environment. Recently, de Jong (2010) challenged both the research and assumptions underlying and cognitive load theory, noting that in practice the different types are indistinguishable from one another; variations in instructional format influence both the nature and distribution of cognitive load, individual learner differences are rarely accounted for, and that efforts to measure cognitive load often fail to provide valid differentiated estimates. He further proposed that cognitive load efforts be designed to measure perceived “difficulty of the subject matter. . .of interacting with the environment itself. . .helpfulness of the instructional measures used” (p. XXX). These issues are especially relevant during student-centered learning where distinctions between and among different types of cognitive load are typically individually differentiated based on prior related knowledge and experience and the individual learning goals pursued. It is problematic to anticipate which resources and activities are extraneous, intrinsic, or germane independent of the individual’s learning goals, their particular background knowledge and experience. Since students must assess veracity and relevance while attempting to address their individual learning goals and monitoring their understanding, research is needed to examine how cognitive load theory and constructs vary as learners become increasingly facile with, or frustrated by, their individual learning tasks.

Student-Controlled Instruction ▶ Learner Control Students’ Attitudes Toward Math Learning JAIME R. S. FONSECA Higher Institute for Social and Political Sciences, Centre for Public Administration and Policies, Technical University of Lisbon, Lisbon, Portugal Synonyms Attitude toward mathematics (ATM) is the student’s organized predisposition to think, feel, perceive, and behave toward mathematics (Jovanovic and King 1998); ATM is an aggregated measure of “a liking or disliking of mathematics, a tendency to engage in or avoid mathematical activities, a belief that one is good or bad at mathematics, and a belief that mathematics is useful or useless” (Neale 1969, p. 632); ATM Scale measures an individual’s feelings, interests, and predispositions toward mathematics (Askar 1986). Students’ Attitudes Toward Math Learning Definition Following Kulm (1980, p. 358), it is probably not possible to offer a definition of ATM that would be suitable for all situations, and for Daskalogianni and Simpson (2000), the definition of attitude assumes the role of a working definition, because they view the attitude construct as functional to the researcher’s self-posed problems. However, there are basically definitions by dimensions, as follows: 1. Multidimensional definition, which deals with three components: emotional response, beliefs regarding the subject, and behavior related to the subject. From this point of view: (a) ATM is defined by the emotions that she/he associates with mathematics, having a positive or negative value, by the individual’s beliefs toward mathematics, and by how she/he behaves (cf. Hart 1989). 2. Bidimensional definition, in which behaviors do not appear explicitly: (a) ATM is seen as the pattern of beliefs and emotions toward mathematics (Daskalogianni and Simpson 2000). 3. Unidimensional definition, which describes it as positive or negative degree of affect associated with a certain subject: (a) ATM is just a positive or negative emotional disposition toward mathematics (McLeod 1992; Haladyna et al. 1983). Theoretical Background One of the most important properties of people is that they have a learning ability. We learn the behaviors which are necessary in our lives, through the effects of our environment and our inherited intelligence; the learning skills of an individual affect her/his life style continuously (Orhun 2007), and for this reason, modern societies try to improve the learning methods in their educational systems continuously. Human beings spent a long time growing up and learning how to act in the world compared with other creatures, and nowadays, the necessity of lifelong learning extends this long learning time even more (Tennyson and Schott 1997). Instructional design is a field of study concerned with improving student learning. Because of the low uptake of mathematics and science S 3215 and the negative attitudes toward these subjects, the decline in the number of science-based students as a proportion of all students eligible for higher education has raised cause for concern about the nation’s economic future (Dearing 1996). The underlying metaphor of learning as an act of increasing individual possession – as an acquisition of entities such as concepts, knowledge, skills, mental schemas – comes to this scholarly discourse directly from everyday expressions, such as acquiring knowledge, forming concepts, or constructing meaning (Sfard 2006). Learning style is a central personality dimension between learning preference and cognitive form. There are several learning style definitions, and in Table 1 we can see four of them. Slavin (1991) asserted that positive effects of cooperative learning have been consistently found on such diverse outcomes as students’ self-esteem, intergroup relations, acceptance of academically handicapped students, attitudes toward school, and ability to work cooperatively, and contemporary ideas on the nature of human learning also contribute to the instructional practice of cooperative learning (Antil et al. 1998).

S 3216 S Students’ Attitudes Toward Math Learning The promotion of favorable attitudes toward science, scientists, and learning science, which has always been a component of science education, is increasingly a concern for science education (Osborne et al. 2003). Table 2 displays what several authors meant by attitudes toward science (ATS). Developing positive students’ ATS is a critical part of science learning (Head 1989); students’ attitudes are linked to their achievement in science and their Students’ Attitudes Toward Math Learning. Table 2 Attitudes toward science Authors What is meant by ATS? Klopfer (1971) ● The manifestation of favorable attitudes toward science and scientists ● The acceptance of scientific enquiry as a way of thought ● The adoption of scientific attitudes ● The enjoyment of science learning experiences ● The development of interests in science and science-related activities ● The development of an interest in pursuing a career in science or science-related work Gardner (1975), Haladyna et al. (1982), Oliver and Simpson (1988), Talton and Simpson (1986), Breakwell and Beardsell (1992), Talton and Simpson (1987), Crawley and Black (1992), Piburn (1993), Koballa (1995) ● The perception of the science teacher ● Anxiety toward science ● The value of science ● Self-esteem at science ● Motivation toward science ● Enjoyment of science ● Attitudes of peers and friends toward science ● Attitudes of parents toward science ● The nature of the classroom environment ● Achievement in science ● Fear of failure on course motivation to persist in science courses in high school and beyond (Kahle and Meece 1994). The current wave of school mathematics reform presents conceptions of content, teaching, and learning that are quite different from the telling model; mathematical content, activities, teaching, and learning are no longer based on the view of students as recipients of knowledge transmitted directly from the teacher (Butty 2002). Advocates of science education reform believe that if students are given opportunities to do science, positive ATS will be fostered (Kahle et al. 1993). ATM is the student’s organized predisposition to think, feel, perceive, and behave toward mathematics (e.g., see Table 3). Important Scientific Research and Open Questions Higgins (1997) found that middle school students trained in problem solving techniques following NCTM recommendations had more positive ATM, and were more persistent in seeking solutions than were students in more traditional classrooms (Butty 2002). Evertson and her colleagues conducted numerous studies of mathematics instruction at the junior high school level (e.g., Evertson et al. 1980); these studies Students’ Attitudes Toward Math Learning. Table. 3 Students’ feelings regarding mathematics Feelings regarding mathematics Positive I have found math to be easy for me throughout school Result I think statistics would be fun For some reason math This gave me the was easy to me as confidence to tackle I was growing up areas of mathematics that were more challenging Negative I have always had a mental block dealing with mathematical formulas I was terrified when I learned that I would have to take Statistics I had a couple of I would feel stupid mathematics teachers and helpless that were sarcastic Students’ Attitudes Toward Math Learning 3217 50 Percentage of students revealed that much more overlap exists between the processes associated with mathematics achievement and those associated with positive academic attitudes (Butty 2002). Classroom organization and instructional variables correlated strongly with achievement, and measures of teachers’ personal qualities correlated highly with student attitudes; investigating the relationship between instructional practices and students’ ATM, they reported that classroom organization and instruction variables correlate more strongly with mathematics achievement, while measures of teachers’ personal qualities correlate higher with students’ ATM. Butty’s (2002) findings showed that 10th grade students with better ATM had a significantly higher achievement score than those with poorer ATM; in addition, students with good ATM in the 10th grade achieved better mathematics scores in 12th grade. In many studies it was found that there is a positive relationship between attitude and achievement in mathematics because students’ mathematical achievement can be influenced by students’ beliefs and attitudes. Recent studies have indicated that male students have positive ATM, more self-confidence in their abilities to learn mathematics, and less mathematics anxiety than female students (Gasiorowski 1998). Concerning sex, Ernest (1976) did analyze an interesting question, concerned whom they got help from in the various subjects; for both girls and boys it is true that the mother helps more than the father, except in the higher grades, where the father helps more in mathematics (and, to a lesser extent, in science). Figure1 indicating this pattern through the grades, for mathematics, is quite striking. Beginning in the sixth grade the father becomes the “authority” on mathematics and continues this role through high school. The results of Orhun (2007) study suggest that there were differences among learning modes preferred by female and male students, their mathematical achievements, and their ATM; in general, students’ ATM are governed by their perceptions regarding the usefulness of mathematics, and their confidence in their ability to learn it; therefore, learning preference and ATM are related to each other. At the high school level, Telese (1997) also found a positive correlation between achievement and attitude among Hispanic students; examining Hispanic students’ ATM and their classroom experiences, he found a higher correlation coefficient associated with S 40 30 20 10 0 2 4 6 8 Grade in school 10 12 To whom do students go for help in mathematics Father Mother Students’ Attitudes Toward Math Learning. Fig. 1 To whom do students go for help in mathematics negative attitudes and traditional activities than positive attitudes, indicating that negative ATM are positively correlated with traditional teaching activities. Fonseca (2007) concluded that students with better ATM until the ninth year (compulsory) of schooling had a significantly higher achievement score on quantitative methods subject than those with poor ATM at the secondary level, but the same did not happen with the data analysis’ performance at University. Math and quantitative methods teaching and learning methodology was quite the same, much more theoretical than practice, and so students who did not like math tended not like quantitative methods; the used methodology in teaching and learning data analysis’ subject, based on computer-assisted teaching and learning, associated to some basic learning skills such as time planning, reading, working in cooperative groups or oral presentation, also contributed for their nonnegative attitude toward knowledge acquisition. However, this methodology goes on with the following question: What does the identification of the powerful ICT-learning potential mean for that large majority of children and students around the world who have no access to computers? Are we facing a technologyfacilitated form of social exclusion (Skovsmose 2006)?

HADWIN University of Victoria, Victoria, BC, Canada Synonyms Learning strategies; Study skills; Study tactics Definition Study Habits ▶ Learning Strategies Study of Psychological Symbols in Socialization ▶ Psychosemiotic Perspective of Learning Study of Symbol-Mediated Thinking and Learning ▶ Psychosemiotic Perspective of Learning Study of Symbols as Thinking Instruments ▶ Psychosemiotic Perspective of Learning Study Skills ▶ Cognitive and Affective Learning Strategies ▶ Learning to Learn ▶ Study Strategies Study Skills Self-Efficacy ▶ Self-Efficacy for Self-Regulated Learning Strategies are repertoires of methods and techniques applied purposefully for specific tasks and task conditions (McKeachie 1988). In contrast to tactics, methods, or discrete study skills, strategies are targeted arrays of behaviors, cognitions, or beliefs directed toward a learning goal or outcome. Strategies are (a) purposeful selections of tactics, (b) deliberately chosen to satisfy specific tasks and self-conditions (IF-THEN), and (c) systematically adapted or fine-tuned in response to their effectiveness in that situation (ELSE; Winne and Hadwin 1998). Theoretical Background Although study skills texts often classify strategies according to type of task (e.g., reading, note taking, and test taking), prominent researchers in the field encourage the use of a processing approach to study strategies. From this approach, strategies are considered tactics purposefully selected to address the interaction of three conditions: (a) task context/condition (e.g., type of task, purpose of task, and complexity of material), (b) processing goals (cognitive, metacognitive, affective, and self-management), and (c) selfconditions (e.g., prior background knowledge about the content, past experience with the type of task, and self-efficacy). Hence, the same study skill or tactic can be used for different types of tasks depending on the individual’s assessment of both the processing required for the task and his/her abilities in relation to the task demands. For example, learners may create a concept map as a tactic to structure information. This technique can be used for a variety of task contexts (e.g., taking notes while reading, taking notes during lecture, and preparing to write an essay) and processing goals (e.g., activating prior knowledge, organizing, and rehearsing). Concept mapping is considered a strategy when learners select it from among alternative S 3220 S Study Strategies techniques to meet their goals for the particular type of task under specific task and self-conditions. As a more concrete illustration, consider a learner who is faced with the task of reading a chapter in his history textbook (task context). Following the IFTHEN-ELSE model for strategies, IF the learner is familiar with the topic and has strong background knowledge of the content (self-condition) and IF he wants to activate his prior knowledge (processing goal), THEN he chooses to create a concept map (tactic) of the information he already knows. ELSE, if he has trouble bringing ideas to mind using the concept map, the learner then incorporates a different tactic of surveying the chapter before reading to get a better sense of the content. This learner is strategically selecting and changing tactics to address the task and self-conditions as well as his goal for processing the information. While strategies may be individualized to match the task, self, and processing conditions, they engage a limited array of empirically supported cognitive, metacognitive, and affective or self-management processes. Brief descriptions of these processes follow. Cognitive processing strategies are directed toward encoding, organizing, and retrieving information. Research consistently identifies five key processes involved in information processing, including activating prior knowledge, selecting and isolating key information, organizing and structuring, elaborating and generative processing, and rehearsal/repetition. Activating prior knowledge involves bringing to mind information previously learned in order to facilitate the processing of new information. For example, before attending a lecture, a learner may first brainstorm ideas about what is known about the topic. In this instance, brainstorming creates a foundation for making connections between the information presented in the lecture and existing knowledge, facilitating understanding, and encoding new information. Other techniques for activating prior knowledge include concept mapping, K-W-L charts (what I already Know, what I Want to find out, what I have Learned), partial outlining, and previewing the textbook. Selecting and isolating key information is the process of distinguishing important ideas or concepts from extraneous and seductive details. Although it does not directly ensure deeper understanding of the information, searching and selecting is a necessary first step to focusing attention on important pieces of information for further processing. A tactic commonly used for selecting and isolating key information is underlining or highlighting. Empirical support for the effectiveness of this tactic is scarce; however, its effectiveness has not always been examined with respect to a selecting or isolating process. Furthermore, this tactic may serve useful functions in combination with elaborative processing tactics. Organizing and structuring information imposes a structure on the information to be learned in order to recognize and understand patterns and connections among ideas and concepts. All information sources have an inherent structure, including description, cause and effect, classification, compare/contrast, timeline, sequence, enumeration, and generalization. Recognizing the inherent structure of information and translating that information into summaries that make those inherent structures salient facilitates encoding, storage, and retrieval. Structuring applies to information presented during lectures, through written text, or across multiple information sources. Learners may strategically organize and structure information by applying one of the following techniques/tactics: compare/contrast charts, concept or knowledge mapping, outlining hierarchies, flowcharts, cause and effect diagrams, and timelines. Elaborating and generative processing helps learners to build a deeper understanding and memory for ideas and concepts and also facilitates transfer. This process involves extending beyond provided information to draw inferences and create meaningful connections between new information and existing knowledge. For instance, learners may generate their own examples of a particular concept to help understand and remember the meaning of that concept. Learners can also use techniques such as summarizing, self-questioning, and elaborative verbal rehearsals. Rehearsing and repeating exposure to information enhances retention of information. Research consistently shows that (a) repetition facilitates recall and (b) repetition combined with deeper processing facilitates better recall than repetition alone. The more exposure one has to material, the greater chance one has of remembering and recalling it. Some methods of rehearsal involve rereading or reviewing material, reciting information, reworking material, and retrieving information from memory. To enhance understanding, rehearsal and repetition should be combined with deeper processes such as elaborating on the material. Study Strategies Metacognition refers to knowing about cognition as well as monitoring and regulating cognition. Metacognitive knowledge includes cognitions about oneself, the task, and strategies for completing the task. Metacognitive processes involve monitoring and evaluating one’s knowledge and learning as well as regulating the factors that influence achievement of one’s goals for learning. Tactics for monitoring and evaluating learning may include activating prior knowledge, selfquestioning, self-testing, and tracking time spent studying. For example, a learner might write down what is known about the topic in a textbook chapter and create questions about what is not known. During or after reading, questions can be answered and understanding is reassessed. The regulatory aspect of metacognition involves planning, evaluating, and adapting or changing strategies based on information provided through monitoring. For example, after monitoring comprehension and evaluating it as low (because he or she cannot answer those questions), the learner may augment a strategy by creating a concept map to relate main ideas in the textbook and lecture. Affective and self-management processes include focusing attention on the task, maintaining or increasing motivation, goal-setting and planning, and managing one’s time, resources, and environment. Examples of techniques to achieve these purposes include self-talk focused on thinking positively, enhancing efficacy, or confidence; reminding oneself of the reasons for doing the task; regulating emotions; and managing time, task goals, or the environment. For instance, a learner may regulate anxiety by practicing deep breathing exercises in order to better focus on the task. Alternatively, a learner may purposefully generate anxiety by thinking about the importance of the task in order to encourage better preparation and performance. Another learner might create subgoals that break down the task into smaller chunks in order to increase motivation for starting the task. Important Scientific Research and Open Questions Study strategy instruction. Researchers in the field recommend training in study strategies should (a) be based on a model of learning in order to enhance transfer, (b) provide empirical evidence for the effectiveness of strategies, (c) include the opportunity for students to practice applying the strategies to their S 3221 authentic academic tasks, and (d) promote metacognitive awareness and self-regulation of strategies, including evaluating the effectiveness and appropriateness of strategies and adjusting or adapting strategies to meet learners’ needs. However, most study skills books and Web sites (a) categorize strategies according to topic area (e.g., time management, reading, note taking, anxiety and stress, and motivation) without identifying the underlying processes (i.e., cognitive, metacognitive, affective) and (b) emphasize the enactment of study tactics without providing support in the strategic self-regulation of tactic use. Study skills instruction could be enhanced by emphasizing processes essential for successful strategy use, including understanding the task and its purpose, setting task-specific goals, enacting study tactics, and evaluating the usefulness of tactics and adapting them to match task conditions and learner needs. Effectiveness of specific study strategies. Empirical evidence for the effectiveness of study skills is weak or mixed at best. The learning processes described above have consistent empirical support but the nature of strategies requires that they be carefully tuned to task, self, and processing demands, which vary greatly among individuals. Of the plethora of study skills, only a handful have been tested, with findings that some are more effective than others. Following is a snapshot of findings regarding some popular strategies, some of which are less effective than many people assume: ● Underlining/highlighting. Although an oft-used strategy, underlining/highlighting has received mixed empirical evidence. Caverly et al. (2000) summarized the research on underlining/highlighting, indicating that this tactic is ineffective if (a) learners are unable to identify main ideas in the first place, (b) the material is long and complex, (c) assessments do not measure concepts that were underlined/highlighted, and (d) learners do not regularly review the underlined content. If learners do choose underlining/highlighting, they should use it in conjunction with other more sophisticated strategies that promote deeper processing of the information, such as annotating in their own words. ● Concept mapping. Research on concept mapping indicates that this is an effective strategy when (a) learners need to engage in deeper processing of the S 3222 S Study Strategies material and retain main ideas rather than memorize details, (b) learners receive instruction in concept mapping and persist in their use of the strategy, and (c) learners can assess task demands and their background knowledge. Nesbit and Adesope (2006) found in their meta-analysis that studying concept maps was somewhat more advantageous for retaining information than studying text passages, lists, and outlines. This finding suggests that the format of a concept map (i.e., arranging nodes in relation to one another and labeling the links) is more effective than other summary formats. More evidence is needed, however, for the effects of using concept maps on higher-level learning, such as transferring knowledge from one context to another. ● Reading comprehension: SQ3R. SQ3R (Survey, Question, Read, Recite, Review) is a commonly taught strategy for monitoring comprehension. Despite its popularity, several reviews have found little evidence for the effectiveness of the strategy as a whole, although the individual parts have received some support. Caverly et al. (2000) concluded that SQ3R requires extensive instruction and practice, especially for learners with low or medium reading ability, along with an awareness of the effort involved in using it. ● Self-questioning. Self-questioning involves generating and answering questions about what is to be learned in the task. Research with this tactic consistently provides support for its positive effect on retention and comprehension. As with any tactic, instruction and training are vital; however, selfquestioning may be easier to learn than other more complex tactics, such as concept mapping. Future Directions Further empirical research is needed to investigate the effectiveness of a variety of strategies, systematically examining the interaction among task conditions, self-conditions, processing goals, and the learning context or environment. For example, what strategies are effective for collaborative learning and for working in computer-based learning environments? Are the strategies used in traditional contexts appropriate for these alternative and increasingly prevalent contexts? How can we best teach learners to experiment with strategies in these contexts? In addition, there is little research examining the effectiveness of individual strategies for regulating motivation and affect. Finally, Weinstein et al. (2000) offer these questions for future directions related to the development, training, and transfer of strategy use: ● What are the precursors of effective strategy use? ● How can we facilitate the development of these ● ● ● ● skills at differing ages? What can we do to help teachers incorporate learning-to-learn activities into their classroom teaching? How do we facilitate high-level transfer across tasks and content areas? How do we help students learn to cue themselves to transfer strategies? How can we help students learn to take more control of their own learning processes and outcomes?

Study Tactics ▶ Study Strategies Studying Expert Solutions ▶ Worked Example Effect Styles of Engagement in Learning MARY AINLEY Psychological Sciences, University of Melbourne, Melbourne, VIC, Australia Synonyms Engagement profile; School engagement profile; Taxonomy of engagement Definition The phrase styles of engagement focuses attention on multidimensional variability in groups of students in regard to the way they connect with learning. When S 3223 a set of motivation or engagement variables are measured for the same group of students identification of distinct response patterns within the set of variables have been referred to as styles of engagement, as school engagement profiles, or as a taxonomy of student engagement. Theoretical Background The central assumption behind the styles of engagement concept is that across any set of attitudinal and motivational variables, combinations of variables provide information that is complementary to descriptions and analyses based on isolating individual variables. Traditional experimental and quasi-experimental designs focus on identifying how separate variables relate to each other and to outcome variables. This has been referred to as a variable-centered approach. In contrast researchers focusing on individuals as complex systems recommend designs that identify how specific variables combine in different members of the population and how the combinations relate to outcomes. This approach has been referred to as a person-centered approach. Analytic techniques such as cluster analysis, pattern analysis, or profile analysis are used to identify subgroups within a sample or population. The assumption is that while traditional variable-centered approaches, such as regression, allow assessment of the contribution of specific predictor variables to an outcome variable, they are not as effective in accounting for the combined effects over a set of variables. Key questions concerning students’ motivation and engagement lend themselves to application of these person-centered approaches. For example, achievement goal theory in a variety of forms is widely used to describe students’ beliefs about the purpose of their learning. Sometimes the learning referent is a specific domain; sometimes learning in general. The psychology of education literature has a wealth of papers describing how aspects of students’ achievement are related to mastery and performance goals, both approach and avoidance. Work avoidance goals also feature in some of this literature. Most commonly achievement goals are conceptualized and measured as dimensions. However, investigation of the overall levels of each dimension separately and its relation to learning outcomes or learning strategies, only provides limited insight into the ways students’ connect with S 3224 S Styles of Engagement in Learning their learning. Each student relates to learning in specific domains, or to learning in general, in terms of a composite of these dimensions. In response, a number of researchers have adopted analytic strategies to identify specific styles, patterns or profiles of achievement goals that might shed further insight into the relations between beliefs about the purpose of learning and students’ achievements. This research is important because it employs analytic strategies “that preserve the multidimensional character of student engagement with learning” (Ainley 1993, p. 395). This development in approach to researching engagement in learning is consistent with the outcome of the extensive review of the literature by Fredericks et al. (2004), who argued that engagement encompasses behavioral, cognitive, and emotional components and recommended that it be studied as a multifaceted construct. Important Scientific Research and Open Questions Two early examples of research studies that identified profiles of student motivation and investigated the relation between these profiles and achievement outcomes are Ainley (1993) and, Meece and Holt (1993). Using an approach to learning measure that distinguishes deep, achieving and surface motivation dimensions, and a measure of general ability, Ainley identified six profiles (styles of engagement) in 11th Grade female students. Students’ styles of engagement were shown to be related to learning strategies when preparing for examinations and to academic achievement in the form of final school grades assessed more than 12 months later. Of particular theoretical interest was the demonstration of the multidimensional character of engagement. The more engaged students expressed relatively high levels of both deep and achieving approaches, and demonstrated a different pattern of strategy use when preparing for examinations than did students with less engaged styles. At a different developmental level (5th and 6th grade students), Meece and Holt (1993) used measures of mastery, ego, and workavoidant goal orientations to identify goal combinations that were significantly related to students’ achievement in science. They argued that using cluster analysis to identify goal orientation profiles generated “a more distinctive and internally consistent set of findings than did pattern analyses that were based on median split procedures” (p. 582). More recently, similar profiles of achievement goals have been reported in a study of 6th grade students (Tapola and Niemivirta 2008) and in a study of the achievement goal profiles of undergraduate students (Daniels et al. 2008). Tapola and Niemivirta (2008) used latent-class analysis to identify multidimensional achievement goal profiles which were reported to be significantly related to students’ preferences for different types of instructional environments. Daniels et al. (2008) used cluster analysis with scores on mastery and performance achievement goal measures to define profiles, capturing the different ways students connected with their learning. These profiles were then assessed in relation to students’ course achievement and to broader features of how they responded to their academic experience, for example, expected achievement, perceived success, and a number of achievement emotions. The analytic strategies adopted by these studies assume that student motivation and engagement is multidimensional and an approach that preserves the multidimensional character of students’ personal orientations to learning will make a significant contribution to understanding the dynamics of student engagement with learning. While the styles of engagement or profiles of goal orientation that have emerged from these studies have demonstrated substantial consistency, the detail of the profiles cannot necessarily be generalized beyond the participating sample and all of the studies reported have been careful not to interpret their profiles as types. Further research is required to establish where the similarities between the profiles identified are in fact general patterns that can be used as a typology or taxonomy. All of the studies referred to so far have based their identification of styles or profiles of student connection with learning on measures of motivation that distinguish goals as beliefs about the purpose of learning (Daniels et al. 2008; Meece and Holt 1993; Tapola and Niemivirta 2008), or approaches to learning (Ainley 1993). These studies have focused primarily on cognitive and to some extent emotional engagement in the sets of dimensions investigated. In contrast, Linnakylä and Malin (2008) using PISA 2003 data focused on engagement in school life and included behavioral engagement indicators in their styles of engagement. Their measures included peer acceptance, student– teacher relations and students’ attitudes to schooling “the extent to which students identify with and value schooling and participate in academic and Styles of Engagement in Learning nonacademic learning activities” (p. 585). Of particular interest in the findings was the lower achievement level of a group characterized by strong peer acceptance and negative attitudes to school. In other research using the styles of engagement concept the purpose has been development of a taxonomy of engagement related to a specific domain of student learning, For example, Bangert-Drowns and Pike (2002) proposed a taxonomy describing 4th Grade students’ styles of engagement with interactive educational software. Unlike the previously described studies based on students self-reports of their motivational orientations, Bangert-Drowns and Pyke identified students’ styles of engagement based on teacher observations and ratings of how students went about working with interactive educational software. The purpose of the research was to develop a taxonomy of levels of engagement to support teachers in distinguishing “different qualities of student engagement, so they can better anticipate and respond to different qualities of student learning” (Bangert-Drowns and Pike 2002, p. 23). The taxonomy defines seven levels of engagement that form a hierarchical structure. At the base of the hierarchy are three types of engagement that are described as problematic: disengagement, unsystematic engagement, and frustrated engagement. A second level within the taxonomy represents competent engagement where students are responding to the structure of the problem. Another three types of engagement represent the third level of the engagement hierarchy and are referred to as self-regulated interest, critical engagement, and literate thinking. Fundamentally, these styles represent differences in students’ skill base and in the ways they use their skills to interpret information and to apply efficient thinking strategies to evaluate the structure of the interactive tasks. To use the taxonomy, teachers rate each student on the frequency that they display each of the seven levels of engagement in their interaction with educational software. For each student, this generates a profile of their style of engagement. In the validation study, students’ style of engagement was significantly correlated with reading test scores. To some extent, reference to styles of engagement begs the question concerning the nature of engagement. The research referred to used different types of indicators of motivation and engagement. The studies by Ainley (1993), Meece and Holt (1993), Tapola and S 3225 Niemivirta (2008), and Daniels et al. (2008), have used measures of students’ motivational orientations to define ways that they connect with their learning. On the other hand, Bangert-Drowns and Pike (2002) have used ratings of students’ participation in specific classroom activities as indicators of engagement, while Linnakylä and Malin (2008) using data from PISA 2003 have used students’ self-ratings on issues of “peer acceptance, student-teacher relations and perceptions of the value of school and education for the future” (Linnakylä and Malin 2008, p. 583) as indicators of engagement. The variety of indicators used by these researchers is characteristic of the literature on student engagement and was highlighted by Fredericks et al. (2004) and is likely to be debated further. In this context, the styles of engagement concept emphasizes the need to preserve the multidimensional character of students’ ways of connecting with learning.

Styles of Learning and Thinking: Hemisphericity Functions KALPANA VENGOPAL Regional Institute of Education, Mysore, Karnataka, India the students, such students are frequently seen to be uninterested in the class, feel bored, and reject the learning activity. Since any subject can be taught in any way that is compatible with any style, students will seek learning activities that are compatible with their own preferred styles. Both teachers and students tend to exploit their preferred styles, which may or may not match. Therefore, it is important for the teachers to know the students-preferred styles, so that the teachers can capitalize the opportunities for students’ learning. Styles like abilities are not etched in stone at birth. They are in large part developed by environmental condition and by way of nurturing children by their parents and teachers. Some individuals may have one preferred style at one stage and another preferred style at some other stage. Styles are not fixed, but changeable. Research tools are readily available to identify the individual’s preferred style of learning. Synonyms Hemisphericity Ways of learning and thinking Hemisphericity is the cerebral dominance of an individual in retaining and processing modes of information in his own style of learning and thinking. The human left cerebral hemisphere is to be specialized for primarily verbal, analytical, abstract, temporal, and digital operation and that the right cerebral hemisphere is to be specialized for primarily non-verbal holistic, concrete, creative, analogic, and aesthetic functions. The specialized functions of each hemisphere appear well lateralized and established early in life and barring special intervention or insult, continue essentially unaltered throughout the normal life span. Tools have been developed to study the “Style” of Learning and Thinking and hence it would be possible to infer the dominance of an individual (Venkataraman 1994). Definition The differences in preference of the two hemispheres for retaining and processing of information in one’s own style of learning and thinking is known as styles of learning and thinking. Hemisphericity is the cerebral dominance of an individual in retaining and processing modes of information in his own style of learning and thinking. Theoretical Background Styles depend upon cerebral dominance of an individual in retaining and processing different modes of information in his own styles of learning and thinking. Styles indicate the hemisphericity functions of brain, and students learning strategy and information processing are based on the preferences of the brain area. Styles are propensities rather than abilities. They are the ways of directing the intellect which an individual finds comfortable. The style of learning and thinking are as important as levels of ability, and we ignore to identify and develop students’ thinking styles at their earlier and appropriate stage. It is foremost important for the teachers to focus their attention on students’ favored thinking styles before imparting the subject matter. If mismatch exists between the preferred styles of the teacher and that of SOLAT The differences in preference of the two hemispheres for retaining and processing of information in one’s own style of learning and thinking is known as styles of learning and thinking (SOLAT) by Torrance (Reynolds and Torrance 1978). The SOLAT tool is based on the hemisphericity functions of the brain. It identifies hemisphericity dominance by way of studying the hemisphere functions. It indicates a student’s learning strategy and brain hemisphere preference in problem-solving. Styles of Learning and Thinking: Hemisphericity Functions Psychological Activities Related to Hemispheric Function Right Hemisphere The right hemisphere has remained underestimated and even today neurophysiologists cling to the view that the right hemisphere is a mere unconscious automation, while we live in left hemisphere. It has a great neuronal capacity to deal with informational complexity. This hemisphere matures earlier than the left hemisphere and the balance between two in children is not similar to one found in adult. The right hemisphere has a greater ability to process many modes of information within a single cognitive task, while the left hemisphere is superior in tasks which require fixation upon a single mode of representation or execution. ● Language: Language function is somewhat more ● ● ● ● equally shared between the hemispheres before the age of 5. The primary expressive mode of the right hemisphere speculates to be metaphorical in nature; however, in general, verbally communicative ability of the right hemisphere is relatively limited and dependent upon the left hemisphere, and complimentary non-verbal functions are carried out by the right hemisphere which is dominant in left-handed people. It coordinates the voluntary motor activities of the left side of the body. Visual Patterns: The interpretation of complex visual patterns is predominantly the right hemisphere function. The retention of visual patterns, such as geometric designs and graphs, is believed to be in the domain of the right hemisphere. Facial Identification: The right cerebral hemisphere is involved in face processing. Right hemisphere superiority is greater for upright than inverted faces and that it involves both perceptual and memory components. Motor: Awareness of body position, spatial orientation, and the perception of fine and gross motor activities all come within the realm of the right hemisphere. Tactile perception is also a right hemisphere function. Creativity: The clinical studies do not enable one to conclude about the specific location of creativity in the brain, i.e., in the right or the left hemisphere. However, it is clear that creativity will not occur without the full participation of a well-developed S 3227 right hemisphere. The left hemisphere also provides variety of elements, for instance, information which is indispensable for creativity. There is a general agreement in creativity researches also that information is a basal factor in creative thinking. The right hemisphere may be more intuitive, imaginative, insightful; has a rudimentary verbal conceptual scheme, aesthetic experiences; produces visual imagery; sees things in a broader perspective; uses the information from the left hemisphere to elaborate, to form new combinations, and to attribute new meanings to it. ● Music: Research has stressed the importance of music and musical instruction in stimulating the right hemisphere. The brain is organized at birth to obey musical stimulation in the right hemisphere. Speech is a function primarily of the left hemisphere, while song is a function of the right (Kane and Kaane 1979). ● Problems: The right hemisphere is able to overcome the most difficult logical and systematic problems which we would conjecture, relaxing the right standards of thought of the left hemisphere. The right cerebral hemisphere makes an important contribution to human performance. It is the neural basis of our ability to take in fragmentary sensory information and from it construct a coherent outside world, a sort of cognitive spatial map within which we plan our actions. Left Hemisphere Each hemisphere is capable of functioning in a manner different from the other. For many years attention was focused on the left hemisphere in which speech was localized the so-called “dominant,” “leading,” or “major” hemisphere. It was hypothesized that this hemisphere was primarily responsible for the processing of language and planning, the two functions which clearly distinguished men from the rest of the animal kingdom. It has been found to be anatomically larger than the right hemisphere, as evidenced by neonatal studies. It is considered to be more active than the right hemisphere in most adults, as indicated by EEG analysis. The left hemisphere apparently specializes in sequential logical, variable, symbolic, convergent production, and logic functioning. ● Speech: Short-term memory is primarily the func- tion of left hemisphere. Expression of language S 3228 S Styles of Learning and Thinking: Hemisphericity Functions through speech is exclusively processed in the left hemisphere. Disturbed speech follows left but not right hemisphere lesions. ● Learning: The left hemisphere is involved in learning the 3 R’s, and reading is considered to be principally a left hemisphere function. The mathematical functions, particularly calculations and algebra are left hemisphere operations. The left hemisphere is well suited for the “education of relation” which is essentially the ability to analyze the common aspects of a task and formulate systematic relationship among these tasks. ● Analytical Thinking: The left brain functioning is involved in sequential operations, analytical/logical thinking, explaining, describing, recalling the verbal content and the operations related with words. This hemisphere is considered to be a rational linear mind specializing in sequential processing, logical, and analytical thinking. Class Preference Right hemisphere: Get clarity while learning experimentally; learning everything by synthesizing, like concrete learning, slow acquisition of habits, not interested in games and sports. Left hemisphere: Get clarity through logical reasoning, understanding better while learning critically and analytically, likes to learn in an abstract way, interested in games and sports. Learning Preference Right hemisphere: Divergent, concentrates on several things simultaneously, competitive, unsocial, mysterious, greater tolerance, and adjustment. Left hemisphere: Convergent, concentrates on one thing at a time, individuality, social, active, no tolerance tendency. Interest Preference Specialized Information Processing Preferences Associated with Hemisphericity and Styles of Learning and Thinking Under Different Dimensions Learning Style Verbal Right hemisphere: Understanding movements of action, talking while reading or writing, learn best by instruction which uses visual presentation, likes to draw more pictures, expression of feelings through music, dance, and poetry. Left hemisphere: Understanding verbal explanations, getting things quiet while reading or studying, learn best of instruction which uses verbal, likes to talk and write, expression of feelings and thoughts in plain language (or open mindedness). Right hemisphere: Invent something new and imaginative; likes to solve complex problems, artistic and aesthetic, interested in funny things. Left hemisphere: Improve upon something, likes to solve simple problems, temporal interest. Thinking Style Logic/Fractional Right hemisphere: Holistic approach, recall faces, retention and recalling shapes and figures, a good command over total memory and tonal, organizing capacity to show the analogy. Left hemisphere: Fractional approach, recall names, retention and recalling numerical figures, analyzing speech and sound qualities, sequence of ideas analogical relationship. Divergent/Convergent Content Preference Right hemisphere: Interest in soft sciences, open-ended lessons, likes to learn through main ideas/basic concepts, writing/likes fiction, learning through exploration. Left hemisphere: Interest in hard sciences (vocational interest in engineering), structured lessons, likes to learn through details and specific facts, writing non-fiction, learning through examining. Right hemisphere: Deductive learning, independent thinking, deep thinking while lying down, easily find directions in strange surroundings, likes to make guesses. Left hemisphere: Inductive learning, mentally receptive and responsive to what is heard and said, deep thinking while sitting erect, easily find directions in familiar places, not interested in guesses. Styles of Learning and Thinking: Hemisphericity Functions Creative Right hemisphere: Creative thinking, likes to pre-plan, intuitive, judgments through feelings and experience, playful approach in problem-solving. Left hemisphere: Intellectuality, likes to day dream, logical approach in judgments, business-like approach. Problem Solving Right hemisphere: Absent mindedness, optimistic view, absence of repression and suppression, passive, stronger determination and ambition. Left hemisphere: Never be absentminded, pessimistic view, presence of repression and suppression, aggressive/short-tempered. Imagination Right hemisphere: A strong memory and remembrance about images, ability to experiment, tactile perception, imagine, and summarize. Left hemisphere: Memory of language and pictures, processes through rational learning and analytical, lacks haptic or tactile perception, outline, analysis. Activation of Hemispheric Functions Different teaching techniques and methodologies can be adopted to activate and influence the hemispheric functions of the brain. The teaching techniques in schools can be undertaken in consonance with the student’s style of learning and thinking. The teaching and learning procedures must be organized in such a way, that they tone up and activate both the hemispheric functions of the brain in students. S It has been discovered that imagery is the precursor of creativity in both the arts and music, that the right hemisphere activity is the precursor of imagery, and that the positive means of the right hemisphere stimulation through art and music is equally as effective as other incubatory techniques for allaying the left hemisphere function. Besides art and music are play. Through play children gradually develop concepts of casual relationship, the power to discriminate, to make judgments, to analyze and synthesize, to imagine, and to formulate. It gives an opportunity to use imagination, fantasy, and creativity which develop the right hemisphere of the brain. A remarkably effective way of stimulating right hemisphere thinking is, also, the use of metaphors (analogies and smiles). They provide awareness of the relationship between dissimilar objects and situations. Left Hemispheric Functions New concepts can be introduced in an analytical manner with verbal emphasis and importance can be given to the expression of language. Students may be asked to listen to abstract speeches heard in the radios, televisions, public meetings, and symposium. They may be given training in analyzing and identifying different speech sounds and encouraged to give logical reasoning and examples for unknown activities or functions without experimenting in general. Discussions may be arranged on general problems, world affairs from the reading of daily newspapers and magazines. They can be encouraged in writing non-fiction essays and scientific explanations in plain language. Games based on verbal and numerical materials, and events can be encouraged. Right Hemispheric Functions The promising strategy by which to cultivate the right brain is to stimulate the child for a more differentiated perception and by increasing the proportion of direct contact he has with phenomena about which he is learning. The right hemisphere of the brain is characterized by numerous functions and no one particular technique of teaching will suffice to develop these functions. These have to be built through different models of teaching. A combination of models, which shares many features, is perhaps a useful approach to work out a system of teaching in this context such that the inquiry model, inductive, creative training and insight models. 3229 Important Scientific Research and Open Questions Raina’s (1984) work on the right hemisphere shows that it is capable of processing language if the discriminations are uncomplicated (e.g., a positive from a negative statement). The analysis of voice intonation, an integral component of language, appears to be the function of the right hemisphere. When verbal material (or material easily coded into language) is presented to right and left visual fields, most subjects show a rightvisual field superiority presumably due to better right field connections to the left hemisphere (Kane and Kaane 1979). During verbal tasks, whether performed overtly or covertly, increased alpha wave suppression S 3230 S Subculture and a greater evoked response are found over the left hemisphere. The right-handed people with left hemisphere dominance, ordinarily have the speech centers in the left hemisphere. The left hemisphere is restively specialized in verbal functioning and is devoted largely to semantic abilities and functions. It has been found that the left hemisphere alone does not process verbal information. The left hemisphere has also been found to be involved in comprehension and retention of language (Fitzgerald and Hattie 1983). The iconic presentation of information (e.g., graphic displays, diagrams, flow charts, etc.) greatly facilitates both the comprehension and the retention of information. Iconic memory is primarily a function of the right hemisphere (Raina 1984). The hypothesis of right hemisphere participation in dreaming implies that the degree of hemispheric lateralization may contribute to individual differences in dream recall and content. Divergent thinkers are more likely to report dreams when awakened from REM sleep than convergent thinkers. These types of cognitive styles are consistent with the assumed specialization of the right and left hemisphere. High creativity, associated with right hemisphere functioning, is correlated with more fluent dreams in terms of number of words and content elements. With respect to problem solving, the right hemisphere is able to design thought experiments which the left hemisphere cannot, because of its rigidity. It is able to hit upon solutions which can then, of course, be recast into strictly logical terms by the left hemisphere (Kane and Kaane 1979). In terms of analytical thinking, the left hemisphere is far more constrained and it shifts through inputs and reduces functions to logical-rational forms and acts more like a digital computer. It requires structure and order which processes perception and sensory input in logical and linear modes. It functions easily in acquisition of new habit patterns (Fitzgerald and Hattie 1983). Researches done by Reynolds and Torrance (1978), and Fitzgerald and Hattie (1983) indicate that it is possible to modify a person’s preferred style of learning and thinking over relatively brief period (6–10 weeks). It is also possible to control the general direction of the changes in the style of learning and thinking with the knowledge of styles of learning and thinking mechanism. It may also be possible to train individuals to modify their information processing procedures to best fit their demands of the cognitive tasks.

Subculture ▶ Microculture of Learning Environments Subgoal Learning RICHARD CATRAMBONE School of Psychology, Georgia Institute of Technology, Atlanta, GA, USA Synonyms Goals; Hierarchical structure Definition A subgoal represents the purpose of a set of steps. When people learn a procedure, they frequently memorize Subgoal Learning a linear series of steps for reaching a solution or accomplishing a task. The drawback to learning just a series of steps is that those steps by themselves contain little or no information regarding how they can be modified. As a result, learners have difficulty solving ▶ novel problems or adapting old procedures. However, if those steps are connected to subgoals, then the learner can use the subgoals to guide his or her search for which steps to alter in order to solve the problem. Subgoals provide organization and help constrain the piece(s) of the procedure on which to focus. Thus, new problems or tasks that share the same subgoals with the already-learned procedure will be more likely to be solved by the learner. Theoretical Background Learners have difficulty solving problems that involve more than minor changes to the procedure demonstrated by training problems or examples (e.g., Catrambone 1998; Reed et al. 1990). People tend to form solution procedures that consist of a long series of steps – which are frequently tied to incidental features of the problems – rather than more meaningful representations that would enable them to successfully approach new problems. Thus, if they are given a new problem that seems similar to an old one – at a ▶ surface level – they will try to apply a set of steps from the old problem. Presumably one of the jobs of education is to equip people to deal with novel problems and situations, not just a small recognizable set. Yet it appears that this job does not get done. A promising approach would be to help people organize their problemsolving knowledge in some way that ties the steps to a meaningful hierarchical structure (e.g., Anzai and Simon 1979; Catrambone 1998; Newell and Simon 1972). This organization is more consistent with the way that experts solve problems (e.g., Larkin et al. 1980). While an expert’s conception of how to solve problems does not necessarily tell us how to instruct novices, it does provide guidance on the types of organizing elements that might be useful for the novice to form. The term “subgoal” has been used in at least two ways in the problem solving and transfer literatures: (1) something generated by a learner when he or she reaches an impasse during problem solving (e.g., Newell and Simon 1972), and (2) a feature of a task structure S that can be taught to a learner (e.g., Catrambone 1998). This latter definition is the focus here. Subgoals show the breakdown of a problem-solving procedure into sub-problems (Anzai and Simon 1979). Problems within a subsection of a domain typically share the same subgoals. The steps for achieving those subgoals will differ across problems. Suppose a learner is attempting to achieve a particular subgoal in a novel problem and discovers that the old set of steps, perhaps learned from an example, will not work. If the learner has learned subgoals, then he or she will have a reduced search space to consider when changing the procedure: the steps associated with the current subgoal. In contrast, a learner who has learned a solution procedure consisting of a single goal reached by a long series of steps will have a larger space to search, and thus will be less likely to determine which steps to modify. Procedures can be analyzed to identify the goals, subgoals, and steps. Such an analysis has important implications for training skills because it can help instructors and instructional designers (e.g., textbook writers, multimedia learning environment developers) present material to emphasize the subgoal structure. The premise is that learning materials that present a well-developed subgoal organization will lead to more efficient learning, better retention, and an increased likelihood that the learner can flexibly apply and generalize the information to new situations. Consider a student who studies the following worked example (adapted from Reed et al. 1990): Tom can mow his lawn in 1.5 h. How long will it take him to finish mowing his lawn if his son mowed one fourth of it? Solution:   1  h þ :25 ¼ 1 ! ð:67  hÞ þ :25 ¼ 1 1:5 ! :67  h ¼ :75 ! h ¼ 1:13hrs; where h is the number of hours worked. A student might learn from this that the way such “work” problems are solved is to take one person’s time and divide 1 by it, multiply it by the unknown, add the amount that was already done, and set it all equal to 1. Such an approach would not be successful for the following problem (also adapted from Reed et al. 1990): 3231 S 3232 S Subgoal Learning Bill can paint a room in 3 h and Fred can paint it in 5 h. How long will it take them if they both work together? Solution:     1 1  h þ  h ¼ 1 ! ð:33  hÞ þ ð:20  hÞ ¼ 1 3 5 ! :53  h ¼ 1 ! h ¼ 1:89hrs: These problems cannot be solved using the exact same set of steps, but they share the same subgoal structure: represent each worker’s work rate and represent how long each worker worked. These subgoals might also involve calling on lower-level subgoals to find a worker’s rate or how long the worker worked. Thus, these subgoals represent mini-problems in the context of solving the overall problem. Important Scientific Research and Open Questions Relatively little research has been conducted on how learners form subgoals; most efforts have been directed toward predicting transfer by learners assumed to already possess the subgoals. One attempt to explain how subgoals might be learned was made by Anzai and Simon (1979). They recorded the moves and verbal protocol of a learner as she solved the Tower of Hanoi problem multiple times. Over trials the learner began to chunk groups of moves. That is, she would make a set of moves in quick succession (a “burst”) followed by a pause before the next set of moves. Anzai and Simon argued that each burst of moves represented a chunk. Each chunk may have reflected a subgoal the learner was achieving by the particular set of steps. Anzai and Simon (1979) suggested that subgoal acquisition is greatly aided when the search space for operators (e.g., possible moves in the Tower of Hanoi problem) is constrained. When the search space is constrained, working memory load is reduced. One hypothesized advantage of a working memory load reduction is that a learner is better able to notice and remember a sequence of steps that led to a particular outcome. In Anzai and Simon’s model, this working memory load reduction aids subgoal formation because a subgoal is formed when learners are working toward a certain goal and notice that a set of steps puts them in a situation that allows them to ultimately achieve the goal. Learners will be better able to notice the result of the first set of steps, and be able to chunk that sequence of steps, if working memory load has been reduced (see also Sweller (1988)). The “subgoal learning model” (Catrambone 1998) assumes that if a learner is cued that a set of solution steps belong together, he or she will be more likely to try to self-explain why those steps belong together, that is, to determine their purpose. This is similar to one of the types of self-explanations that Chi and her colleagues have observed as students studied various texts in physics and biology (e.g., Chi et al. 1989). The subgoal learning model can be summarized as follows: 1. A cue leads learners to group a set of steps. 2. After grouping the steps, learners are likely to try to self-explain why those steps go together. 3. The result of the self-explanation process is the formation of a goal that represents the purpose of that set of steps. While most learners can presumably engage in a self-explanation process with varying degrees of success, good students seem better at determining the appropriate boundaries between meaningful groups of steps in a solution procedure (Chi et al. 1989). The use of a label in examples might serve as a cue to the boundaries. A reasonable question to ask at this point is: why not directly state the subgoals to learners rather than embedding them in examples? There are two problems with this approach. First, a variety of studies have shown that learners exhibit a clear preference for learning from and referring to examples when faced with new problems. Further, adding examples to training materials aids learning. Second, although there have been a small number of successes teaching solution procedures directly, most attempts have been unsuccessful. These attempts to teach procedures directly might have failed though because the materials encouraged learners to memorize the steps, instead of forming subgoals that organized the steps. Thus, the efficacy of direct subgoal instruction remains an open question. Research suggests that appropriately designed examples are an effective way to help learners to form more generalized solution procedures such as ones organized around subgoals. The methods learned to achieve those subgoals will possibly need to be adapted when the learner encounters new problems. A learner Subitizing will have a better chance of adapting a solution procedure that is organized by subgoals, and methods for achieving those subgoals, compared to a solution procedure that consists only of a long series of steps. However, systematic research still needs to be conducted on exploring a variety of ways to aid subgoal learning.

Subitization ▶ Subitizing S 3233 Subitizing HENRY RAILO1, MINNA M. HANNULA-SORMUNEN2 1 Department of Psychology, University of Turku, Turku, Finland 2 Department of Teacher Education and Centre for Learning Research, University of Turku, Turku, Finland Synonyms Subitization Definition ▶ Subitizing, a term coined by Kaufman and colleagues (Kaufman et al. 1949), refers to a fast and highly accurate, effortless process by which a small number of items can be enumerated without counting. Consider, for example, that you are viewing a pool game and that at some point you are asked to report how many balls are on the table. If there are only three balls on the pool table, you can determine their number with little difficulty and high confidence. However, if the number of balls is higher, say seven, you probably cannot quantify their number just at a glance, but you must count them one by one or in groups. The range of numbers of items that can be enumerated without counting is termed subitizing range. Although estimates of the subitizing range differ between studies, and individual and developmental differences are known to exist, subitizing range is nowadays usually considered to range from one to about three or four objects in adults, and from one to about two to three in children under school age. Theoretical Background The difference between enumerating small and larger sets of objects has attracted researchers from the very beginning of psychological science, and the question is entangled with a more general issue of capacity-limited processes of the cognitive system. In 1860, William Hamilton, following earlier philosophers, wondered how many objects could be apprehended at once. By casting a varying number of marbles on the floor and examining how many objects he could view at once without confusion, Hamilton concluded that the mind S 3234 S Subitizing is able to ingest up to six items at a glance, reasoning that “the greater the number of objects among which the attention of the mind is distributed, the feebler and less distinct will be its cognisance of each.” (Hamilton 1860, p. 254). Subsequently, enumeration of small and larger arrays has been studied in more controlled situations (e.g., Jevons 1871; Kaufman et al. 1949; Trick and Pylyshyn 1994). In a typical experiment, participants are asked to report the number of visually presented objects as fast as possible. The classical finding is a slope of response times that reminds of a hockey stick, in other words, enumeration times do not increase linearly as the number of items to be enumerated increases. For the first few items, each additional object increases response times only slightly (60 ms per item), but after three or four items, every additional object increases response times more dramatically (300 ms per item). When participants are asked to enumerate briefly presented arrays of items, enumeration accuracies and participants’ confidence ratings show a similar trend: Enumeration of small numbers is highly accurate and confident, whereas if the number of objects is about four or higher, enumeration is more error prone and the participants more uncertain of their answers. The fact that enumeration is highly accurate in the subitizing range demonstrates that subitizing is not merely estimation of number, but a process through which number can be recognized accurately. The view that subitizing and counting are different processes is supported by neuropsychological patient data showing that patients who demonstrate clear deficits in counting may still be able to enumerate small sets of numbers accurately (Dehaene and Cohen 1994). In addition, functional brain imaging studies have demonstrated that enumerating small and large sets of items rely on partly different brain circuits. It is important to note that subitizing and counting are means by which number can be determined, they do not directly tell the mechanism by which number, or quantity in general, is represented in the brain. It has been proposed that small numbers of objects can be represented discretely through separate indexes and, thus, practically without an error, whereas larger quantities are coded by continuous and variable magnitude representations. The ability to individuate small numbers of objects has been proposed to play a key role in the development of numerical competence. Important Scientific Research and Open Questions A number of theories have attempted to explain how enumeration of small sets of items differs from counting (see Trick and Pylyshyn 1994). Theories have suggested that subitizing is merely fast counting, recognition of canonical patterns associated with number words, or that subitizing would reflect a capacity limitation of the visual system, attention, or working memory. Nevertheless, despite decades of research, the exact processes involved in subitizing remain elusive. One of the most influential theories has proposed that subitizing and counting rely on different attention mechanisms (Trick and Pylyshyn 1994). According to this view, subitizing is based on a preattentive parallel processing stage during which a few items are individuated, although it is acknowledged that subitizing is an intentional process and, thus, also constitutes an attentional component. Counting was, unsurprisingly, deemed to be a serial, attention-demanding process: Items or groups of items are selected one after another, which is reflected, for example, in the fact that quantification times increase considerably as the number of counted objects increases. Recent evidence has, however, shown that manipulations that minimize attentional processing compromise, not only counting, but also subitizing. This demonstrates that also subitizing is dependent on attentional resources (Railo et al. 2008). Despite the fact that subitizing is an attention demanding process, the theory that subitizing and counting recruit different attentional processes remains viable. Attentional resources might enable the individuation or conscious apprehension of a few objects at a time, while enumerating a higher number of objects requires additional attention-dependent processes, such as updating the contents of working memory. It is yet unsolved whether subitizing is a strictly visual process, or if auditory or tactile stimuli could also be enumerated by subitizing. This is a significant issue as it might reveal important insights into the underpinnings of subitizing – whether subitizing reflects a modality-specific capacity or a general limitation in the ability consciously access perceptual Subject of Learning information. Some studies have suggested that enumeration of tactile and auditory stimuli do reveal two different quantification processes, but other studies have reached an opposite conclusion. Even if an auditory or a tactile task would reveal the characteristic hockey-stick function in reaction times and error rates, conclusions would not necessarily be straightforward. For instance, what if an individual’s subitizing range, or slope, is clearly different between visual, tactile, and auditory modalities? Could all nonetheless exhibit subitizing? It is known that subitizing performance can be modified not only by changing the experimental procedure (e.g., the presentation time or pattern of the items), but also by training, both in adults and in children. Thus, subitizing can be aided and modified by other processes, although how this exactly happens is an outstanding question. Likewise, the developmental role of subitizing on later numerical skills needs to be understood better. How do babies’ capabilities of small-number discrimination become explicit smallnumber representations linked to number words, and how do these early verbal number skills develop further to verbal counting skills?

S 3235 Subject of Learning FRANZ SCHOTT Department of Psychology, Technical University Dresden, Dresden, Germany Synonyms Learned change of behavior potential, learned competency, learned ability Definition The subject of learning is what is learned. Learning is defined as a change in the behavior potential of a system (a change in competence or ability) in a given situation caused by experience and sustained for some time (e.g., Bower and Hilgrad 1981, p. 11). The system can be a human being, an organism, or a machine. In the context of learning, the meaning of “behavior” is understood in a broad sense, comprising operations such as moving, thinking, wishing, feeling, or processing information. The behavior potential of a system describes a certain competency (ability), for example, knowledge of Canada, or a part of a competency, for example, knowing the capital of Canada. It is not observable. What is observable is the performance which refers to a certain competency, for example, a person says “The capital of Canada is Ottawa.” The learned change of a behavior potential in a given situation is the subject of learning. It is important to realize that every subject of learning describes a change. A behavior potential or a competency itself is not a subject of learning. Therefore, learning objectives, learning outcomes, and learning content are not subjects of learning. For example, a person learns something about Canada: The change from that person’s previous knowledge to the knowledge he or she possesses when reaching the learning outcome or the learning objective is the subject of learning. The meaning of “subject” as a human being, such as in the statement: “A subject is a being which has subjective experiences,” is not what is meant here. There is a large variety of different subjects of learning. They depend on the type of behavior that is acquired, for example, thoughts, emotions, motivations, observable behavior of human beings, or processes of a computer in a machine, as well as on the S 3236 S Subject of Learning domain of the behavior, for example, mathematics, various disciplines in science and humanities, music, painting, sports, cooking, information technology. Theoretical Background Because common definitions of learning view the subject of learning as a change in behavior potential (ability, competency), a theoretical analysis of the subject of learning has to clarify what in this context is meant by “change,” “behavior,” and “behavior potential.” Let us begin with the concept of behavior. One general characteristic of any behavior is a change in state. If nothing happens, there is no behavior. Any change in state can be broken down into a beginning state and a final state. For example: Mary’s behavior in unlocking the front door of her house consists in the beginning state: door is locked, and the final state: door is unlocked. Many behaviors can be broken down into parts of behavior. In our example: taking the key, putting it into the lock, and so on. Each of Mary’s activities of unlocking the front door differs from her previous trails of unlocking it. The set of all these different trails describes a type of behavior: How Mary unlocks her front door. Because learning refers to behavior change that is more or less permanent, the subject of learning is always a change of a type of behavior, not of one singular behavior. Mary is able to unlock her front door; in other words: she has the behavior potential to do it. A behavior potential describes the capability (competency) to execute a certain behavior (performance) in a given situation. The manner in which Mary’s husband unlocks the front door may be different in some ways; it may be more hasty and error-prone. The abstraction from the various types of unlocking the front door (by Mary, her husband, or other persons) describes the set of behaviors necessary for unlocking Mary’s front door. The abstraction of unlocking all doors by using a key describes an even more abstract type of behavior. The more abstract the description of a subject of learning is, the more problems of misunderstanding may occur. Take as an example: “learning to behave as a responsible citizen.” Let us now focus on the concept of “change.” As mentioned above, learning is defined as a system’s change of behavior potential in a given situation. Any behavior describes a change in state. If we call this change a first-order change, a behavior change describes a change concerning a certain change in state, which is a second-order change. In educational settings, a secondorder change of this kind is a change from the inability to execute a certain task correctly to the ability to do so. Take as an example a behavior change in fact knowledge: Mary has to perform a completion test. She reads: “The capital of Canada is . . .?” This is the beginning state of the behavior. She fills in the space with “Toronto.” The final state of this behavior is: “The capital of Canada is Toronto.” This statement is wrong. Mary has to learn. After this learning process, the beginning state of Mary’s factual knowledge in this situation is again: “The capital of Canada is . . .?,” but the final state will be: “The capital of Canada is Ottawa.” The states describe the content aspect of the behavior or task; the change describes the behavior aspect. In our example, the content aspect is “The capital of Canada is Toronto” and “The capital of Canada is Ottawa”; the behavior aspect is completing “The capital of Canada is . . .?” by filling in the name of the capital. Learning is indicated here by the substitution of Toronto by Ottawa. This substitution can be an observable behavior of speaking or writing, but it is also a thinking process. This substitution as a change in behavior potential describes a certain subject of learning. To summarize: The subject of learning is what is learned; learning is a change in a behavior potential (competency, ability) and can be described as a secondorder change. A third-order change of states can define the type of change in the learning process. Important Scientific Research and Open Questions The large variety of subjects of learning leads to the question of whether it is possible to identify universal characteristics for any subject of learning. In the quest for parsimonious explanations, some psychological theories, especially behavioristic ones, reduce all psychological phenomena to two classes of events: stimuli and responses. In these stimulus–response models the subject of learning is a change in a certain response to a given stimulus. Current cognitive theories in psychology focus on information processing as the basis of behavior and behavioral change. When using these theories, we have to ask the question of whether or not a change in behavior can be reduced to a change in information or information processing. We have to take into account Subject of Learning two problems: What is the characteristic of information? And is behavior always physical? The nature of information is not physical. Information is immaterial, but it needs some material to be realized. When Mary has learned that Ottawa is the capital of Canada, she can say or write: “Ottawa is the capital of Canada.” The medium transporting this information can vary: air when spoken, light when written; the information itself remains the same. Additionally, although this information is immaterial, it has a physical basis in Mary’s brain. A change in information by itself or a change in information processing by itself is often not a sufficient condition for a change in a behavior potential. If, for example, Mary wants to improve her tennis serve, the realization of this improvement via learning depends not only on a change in the information process controlling the behavior. This realization also depends on her fitness, the individual structure of her limbs, her potential to strengthen her muscles, etc. In addition, the constraints of the necessary change in information processing in Mary’s brain are not only dependent on logical laws but also on characteristics of her neuronal equipment. Therefore, the analysis of learning and learning subjects is not only a matter of information processing, but also a matter of the characteristics of the system in which the learning happens. It is problematic to equate subjects of learning, as changes of behavior potentials (ability, competency), with changes in cognitive structures, representations, or neural information processing as some researchers do, because this may lead one to confuse the task of describing the subject of learning with the task of explaining learning processes. Since the acquisition of the same subject of learning may be explained by different learning theories, from a methodological point of view it is useful to separate description and explanation. Up to now, no general learning theory exists that can explain all learning phenomena. Accordingly, there is no general theory concerning the subject of learning. The reason for this may be the large variety of different types of subjects of learning. Furthermore, applied research on learning focuses only on specific types of subjects of learning such as those found in mathematics or sports. The development of a general theory of learning requires an analysis of the subject of learning. A general theory of this kind should answer questions like the following: Which characteristics of the subject S of learning are universal and which are specific, depending on the domain in focus (for example: what are typical differences between subjects of learning in the acquisition of mathematics and those in the acquisition of a foreign language)? What kind of influence do these different characteristics have on the processes of learning and what are good explanations for this influence? Looking at behavior as a change in state may offer some possibilities for constructing a general theory of learning. For example, the analysis of the states may help one to quantify the content aspect of a certain behavior by counting the elements and relations describing the state. And one can also quantify the behavior aspect by calculating the similarity between the beginning state and the final state (Schott 1992). Specific structures of states and changes in state can be discovered. A problem in defining subjects of learning is determining which aspects of a whole situation constitute parts of the subject of learning or of the surrounding situation where the behavior takes place. With regard to our example of unlocking the front door, we have to ask: Are the type of lock and environmental conditions such as rain, darkness, and so on parts of the description of the behavior? Or are they parts of the description of the situation where the behavior takes place? In classical ▶ conditioning learning is often described as performing the same response to a different stimulus. But if the stimulus controlling the response is viewed as part of the beginning state of the behavior, classical conditioning also causes a change in a behavior potential. A similar problem is the following: One may ask the question whether or not each behavior describes a change in state. For example: Mary is offered a cigarette and she declines. Is her refusal a change in state; does anything happen? Since her refusal is a reaction to a temptation which can be described as a part of the beginning state of the behavior, it can be interpreted as a change in state. The answers to these questions lead to problems concerning the dependence of behavior and situation and to problems concerning the ▶ transfer of learning.

Substitution error is the automatic replacement of one item in a sentence, strategy, word, or phoneme when the specific information is forgotten or unknown. For instance, when the subject is requested to repeat nonwords immediately after listening to them, he/she might produce “zama” after hearing the nonword “jama.” In this example, the substitution of the phoneme [j] occurred for the sound of [z].

SANTOS Department of Experimental Psychology, UNESP, São Paulo State University, Assis, São Paulo, Brazil Synonyms Error of substitution Theoretical Background In Cognitive Psychology, the term is mostly used to explain errors that occurred on the performance of paradigms, tests, and tasks related to language, memory, attention, calculation, and executive functions. Therefore, substitution error is a general concept in cognition science. In memory research, substitution errors tap on the interaction between linguistic and memory fields (Gathercole et al. 1994). It is well established that in the memory test for nonwords, a short-term memory skill measured by instruments such as CNRep or BCPR, children with typical development will produce a small percentage of errors, whereas children with specific language impairment will perform significantly poorly than their counterparts in this task. Phonemic errors (when the identity of the target item is not present in any position in the repetition) are classified as substitution, omission, and addition while order errors (refer to the movement of the target to nontarget position in the output attempt) are classified as migration. However, the phonotastic rules (syllabic stress, length, spelling, syllabic construction, prosody) of the language determine the characterization of the substitution errors. For instance, in English nonwords the substitution errors mainly occur by the end of the stimuli, while in Portuguese it might happen in both, by the middle and at the end of the nonwords. These differences may be discussed in terms of distinctiveness, clustering, and redintegration hypothesis. Therefore, it is important to obtain specific stimuli for each idiom (Santos et al. 2006; Santos and Bueno 2003). Age effect. The number of phoneme substitution errors decrease in older children, despite the fact that the system capacity remains relatively stable during the development. However, the schooling effect could be a better determinant of the performance since Suggestive Accelerative Learning the phonological awareness improves with the literacy proficiency. Length effect. The length effect reflects the subvocal rehearsal component of the phonological working memory. Thus, more phoneme substitution errors are observed in long over short items. This effect is also observed for Chinese logographemes writing. Wordlikeness effect. The rate of wordlikeness between nonword and general words affects the performance in the nonword repetition task; there is a progressive increase of the substitution error rates from nonwords with high to low similarity with words. Position effect. The pattern of errors in nonword repetition depends on the phonotactic rules of the language. For instance, in Portuguese 5-syllablepseudoword errors occur mainly in the middle of the stimuli (third syllable), before the syllabic stress. However, substitution errors also appear more in the end of stimuli (fifth syllable), after the stress. In certain circumstances, positional errors result from impairment to an abstract ordinal code with graded activation of letter positions from first to last, and this code is specific to tasks involving orthographic representations. Substitution errors can also be investigated by the context of long-term memory (prospective, gist, and episodic memory) using recognition tasks, remembering/knowing paradigms, measures of everyday functioning, and cue detection focused mainly on semantic substitution errors. In language research, the term “substitution errors” is used to describe the pattern of errors production observed in patients with aphasia, dyslexia, dyspraxia and children with specific language impairment dueling with reading, comprehension, writing, and repetition tasks. In general, the pattern of errors is similar to controls but the quantity of error is higher in people with language impairments. Substitution errors in language studies may be associated with the use of the third person singular pronouns, anomia, semantic substitution errors (say “arm” when “leg” is intended), semantic verbs substitution, and substitution of an orthographically similar word with letters that overlap the target either in early or late letter positions. In the language field, substitution errors are investigated mostly in lexical decision, reading, writing, speech production, and comprehension tasks. S 3239 Important Scientific Research and Open Questions A search accomplished on March 14, 2010, at medline/ pubmed using the words “substitution and errors and learning” found 56 articles. After reading their abstracts, only 42 were kept on the list considering the specific subject because in the other studies the word “substitution” was not used as an error type. The period related to these papers ranged from 1976 to 2009. Substitution errors were reported in a variety of subject studies: animal response in discrimination or problem solving tasks (pigeons, rats, monkeys), gender differences in attention, memory or executive function tasks, children or adults’ speech production or reading, cognitive performance of brain-damaged people, psychoactive drug effects, people with dyslexia, apraxia of speech, dyspraxia and aphasia, and mental disorders (dementia, depression, melancholia, schizoaffective disorder, and schizophrenia).

The method was largely inspired by the Bulgarian development of Suggestopedia. It borrowed elements such as the use of Baroque music and the repetitive cycle in the use of three different types of intonation from an experimental version of Suggestopedia. It also added elements such as rhythmical abdominal breathing exercise, and visualization and meditation training from other yogic therapies such as Transcendental Meditation and Sophology. Influences from Yoga and Hypnosis Synonyms Affective Learning; Neuro Linguistic Programming; Speedlearning; Suggestive Accelerative Learning Definition “Superlearning” is the title of a book authored by Sheila Ostrander, Lyn Schroeder, and Nancy Ostrander. It was first published in 1979 and an updated version was published in 1997 as “Superlearning 2000.” The term superlearning also refers to a group of memorization and self-developing techniques. In a broader sense, the term superlearning is often used as a synonym for other learning speedup methods. In a narrow sense, it is a registered trademark at the US Patent and Trademark Office (as of 2009). Theoretical Background Superlearning, as a learning method, claims that it establishes a quick and stress-free learning by enhancing learner’s abilities through suggestion and/or autosuggestion that is directed to the relaxed mind and body. Characteristically, it uses yoga-like breathing exercise, visualization, and meditation training with the help of specified background music. A typical program includes a set of learning materials that consist of a book with the learning content and recorded audio materials. Superlearning is basically designed as a selflearnable program, and it does not necessarily require a teacher and a learning group. Superlearning was created on the basis of journalistic research and interviews conducted in the communist Russia, Bulgaria, and Czechoslovakia in 1967 and 1968 by the authors of the book “Psychic Discoveries Behind The Iron Curtain” (1969). Ten years later, the Superlearning is generally positive about hypnosis. It interprets Suggestopedia as a group of yogic techniques to obtain hypnotic effects in the waking state (p. 66). As a result, it puts special importance on the tempo or the speed of the music as the means to obtain the desirable state of relaxation. It believes that the speed of 60 beats per minute in slow Baroque music can assist the ideal rhythm of breathing to establish the stable appearance of alpha brain waves. It also believes that a cycle of certain beat count (8 or 10 s cycle) can assist learners to obtain a certain hypnotic effect. So-called “New Age Music” is also used in Superlearning for the same purpose. Such music pieces are generally characterized as calm, slow, steady, and “hypnotic” with repetitive phrases and passages. Special intonation used for the “concert reading” also reinforces such an effect. Three types of intonation are repetitively used for each phrase in the textbook when it is read: “(1) normal (declarative), (2) soft whisper (quiet, ambiguous, misleading tone), (3) loud, commanding voice (with a domineering tone)” (p. 69). Use of Suggestions and Relaxation Superlearning preconditions the brain to maximize the learners’ abilities by verbal suggestions directed to the state of physical and mental relaxation. Verbal and direct suggestions are given to the learners so that they believe in their abilities to overcome the limitations built into their personalities. Learners are directed to passively receive the suggestions and the learning contents. The required state of relaxation for such a purpose is measured as the maximum frequency of appearance of alpha brain waves. It claims such relaxation is attained and maintained, without using a biofeedback device, by abdominal rhythmical Superlearning breathing that is paced by the constant “60 beats per minute” rhythm of the music. Important Scientific Research and Open Questions Needs for Distinction Between Superlearning and (De) Suggestopedia Superlearning is often confused with Suggestopedia (or Desuggestiopedia) because of its attribution to Lozanov’s research on yoga and his early success with hypermnesic experiments with nonclinical suggestions. However, such an attribution to Lozanov’s’ research outcomes does not necessarily secure grounds on which one can conclude that Superlearning is Suggestopedia. Rather, Superlearning and Suggestopedia should be considered as two different learning methods as they contradict each other in major aspects of their key concepts such as: (1) attitude toward hypnosis, (2) use of suggestion, and (3) required “relaxation.” For example, whereas Superlearning is positive about the use of hypnosis and tries to give learners control over their mind and body through hypnotic effects, Suggestopedia is consistently negative about the use of hypnosis and tries to give learners control by freeing them from a hypnosis-like state S 3241 induced by the “social suggestive norms.” Accordingly, whereas Superlearning uses verbal and direct suggestions toward the state of meditative deep relaxation, Suggestopedia uses nonverbal and peripheral suggestions toward the state of what it calls “psycho-relaxation” that is very close to waking state (Lozanov 1978). Following table shows other differences in the two methods (Table 1). Previous research made on either Superlearning or Suggestopedia has not been able to confirm the methods’ superiority to conventional teaching methods, and criticism has often been directed at Superlearning or Suggestopedia regarding their lack of scientific consistency (e.g., Scovel 1979; Hagan 2002). However, many such pieces of research and criticism are based on a mixture of the two similar but completely different methods. Each method should be clearly distinguished from the other to be precisely evaluated. Is Superlearning Effective? If So, Why? As mentioned above, Superlearning cannot fully attribute its effectiveness to the success of Suggestopedia because neither yoga nor hypnosis, the main properties of Superlearning, has ever been the central issue in Suggestopedia. It is true that much scientific research has been conducted on yogi, their brain wave patterns, depth of relaxation, and their mental potentials, or Superlearning.

However, this research has not necessarily proven the educational effectiveness of Superlearning. Comparative study in terms of attainment of proficiency against other nonyoga-hypnotic methods may be desirable. Is Superlearning Safe? On one hand, Superlearning is positive about the use of hypnosis, on the other hand, it seems that care is not well taken about the negative side of hypnosis. Lozanov (2009 pp. 47–50) shares his apprehension with Weitzenhoffer (1989) that the use of hypnosis in a nonclinical environment can cause serious problems for the personality of the hypnotized subject. Lozanov points out that the techniques that Superlearning heavily relies on, such as breathing exercise and visualization training, can induce unwanted hypnosis. A longitudinal research study on the relationship Supervised Learning between the effects of such activities and the mental health of the learners is desired. Such research is important for Superlearning to ensure its safety.

As the output is regarded as the label of the input data or the supervision, an inputoutput training sample is also called labeled training data, or supervised data. Occasionally, it is also referred to as Learning with a Teacher (Haykin 1998), Learning from Labeled Data, or Inductive Machine Learning (Kotsiantis 2007). The goal of supervised learning is to build an artificial system that can learn the mapping between the input and the output, and can predict the output of the system given new inputs. If the output takes a finite set of discrete values that indicate the class labels of the input, the learned mapping leads to the classification of the input data. If the output takes continuous values, it leads to a regression of the input. The input-output relationship information is frequently represented with learning-model parameters. When these parameters are not directly available from training samples, a learning system needs to go through an estimation process to obtain these parameters. Different from Unsupervised Learning, the training data for Supervised Learning need supervised or labeled information, while the training data for unsupervised learning are unsupervised as they are not labeled (i.e., merely the inputs). If an algorithm uses both supervised and unsupervised training data, it is called a Semi-supervised Learning algorithm. If an algorithm actively queries a user/teacher for labels in the training process, the iterative supervised learning is called Active Learning. Theoretical Background Figure 1 shows a block diagram that illustrates the form of Supervised Learning. In this diagram, (xi, yi) is a supervised training sample, where “x” represents system input, “y” represents the system output (i.e., the supervision or labeling of the input x), and “i” is the index of the training sample. During a Supervised Learning process, a training input xi is fed to the Learning System, and the Learning System generates an output ỹi. The Learning System output ỹi is then compared with the ground truth labeling yi by an arbitrator that computes the difference between them. The difference, termed Error Signal in this diagram, is then sent to the Learning System for adjusting the parameters of the S 3244 S Supervised Learning yi Training Data Set {(x1, y1), ..., (xn, yn)} xi Learning System ∼ yi Abitrator (−) Error Signal Supervised Learning. Fig. 1 Block diagram that illustrates the form of Supervised Learning learner. The goal of this learning process is to obtain a set of optimal Learning System parameters that can minimize the differences between ỹi and yi for all i, that is, minimizing the total error over the entire training data set. A notable phenomenon is that a minimum training error does not necessarily indicate a good performance in testing. Training is referred to as the learning process that estimates the parameters of the learner based on the ground truth supervised data seen, while testing is to evaluate the predictions of the learner for the data unseen, that is, the data used in testing have not been included in the training process. Therefore, even if a learner achieves a minimum error on the set of training data, it does not guarantee to perform well to the data unseen. The reason for this is mainly due to the possible overfitting to the training data, that is, the learner has an unnecessary order of complexity in learning the mapping. This issue is referred to as the generalizability. A good learning algorithm must have a good generalizability. To take into consideration of the generalizability in designing the learner, a learning algorithm needs to balance the objective of minimizing the training error and the complexity of the learner (e.g., the structure and the order of the learner). For example, in the Support Vector Machine, the generalizablity of the learner is characterized by the margin of the learned discrimination boundary. The larger the margin, the better the generalization. The support vector machine learns a maximum margin classifier over the training set, and thus it naturally leads to a good generalization performance (Vapnik 1995). The Supervised Learning paradigm does not restrict the sources of the input or output data. The input or output may belong to a vector space or a set of discrete values. The learning paradigm does not have special restrictions on the arbitrator either. If yi is drawn from a continuous space, the error signal is usually computed via yi  ỹi. If yi belongs to a set of discrete values, the arbitrator usually outputs the error signal based on the equality between yi and ỹi. For example, the arbitrator may output 0 for equaled yi and ỹi and output 1 for different yi and ỹi. There are different approaches to the design of the Learning System in Supervised Learning. Some well-known approaches include the logic-based approach, the multi-layer perceptron approach, the statistical learning approach, the instance-based learning approach, the Support Vector Machines, and Boosting. Important Scientific Research and Open Questions Advantages and Disadvantages The foremost advantage of Supervised Learning is that all classes or analog outputs manipulated by the algorithm of this paradigm are meaningful to humans. And it can be easily used for discriminative pattern classification and for data regression. But it also has several disadvantages. The first one is caused by the difficulty of collecting supervision or labels. When there is a huge volume of input data, it is prohibitively expensive, if not impossible, to label all of them. For example, it is not a trivial task to label a huge set of images for image classification. Second, as not everything in the real world has a distinctive label, there are uncertainties and ambiguities in the supervision or labels. For example, the margin for separating the two concepts of “hot” and “cold” is not distinct; and it is difficult to name an object that is a cross between a love seat and a bed. These difficulties may limit the Supervised Learning in Spiking Neural Networks applications of the Supervised Learning paradigm in some scenarios. To overcome these limitations in practice, other learning paradigms, such as Unsupervised Learning, Semi-supervised Learning, Reinforcement Learning, Active Learning, or some mixed learning approaches can be considered. S 3245 Supervised Learning in Spiking Neural Networks RĂZVAN V. FLORIAN Center for Cognitive and Neural Studies (Coneural), Romanian Institute of Science and Technology, Cluj-Napoca, Romania Applications Supervised Learning enables a machine to learn the human behavior or object behavior in certain tasks. The learned knowledge can then be used by the machine to perform similar actions on these tasks. Since the computing machinery may perform some input-output mappings much faster and more persistent than the human, machines equipped with a good supervised learner can perform certain tasks much faster and accurate than the human. On the other hand, because of the limitation in hardware, software, and algorithm designs, existing Supervised Learning algorithms still cannot match human’s learning ability on many complicated tasks. Supervised Learning have been successfully used in areas such as Information Retrieval, Data Mining, Computer Vision, Speech Recognition, Spam Detection, Bioinformatics, Cheminformatics, and Market Analysis (Wikipedia 2010). Synonyms Spiking neural networks; Supervised learning Definition In ▶ supervised learning, the learner is presented, for a set of inputs, the desired (target) outputs corresponding to the given inputs. The learner should then learn to predict the correct output for any valid input. Spiking neural networks are neural models, where neurons transmit information through each other by firing action potentials, or spikes, as real neurons do. Supervised learning in spiking neural networks refers to how spiking neurons modify their parameters in order to be able to reproduce and generalize the input–output associations that they were taught in the past.

In the brain, information is exchanged between neurons through action potentials, or spikes. Neurons integrate the spikes received through their input synapses and, when a threshold is reached, they fire spikes at their turn, which are transmitted to other neurons. The effects on a neuron of the spikes received through S 3246 S Supervised Learning in Spiking Neural Networks a particular synapse depend on the synaptic efficacy of that synapse. In artificial neural networks where information is represented by the continuous activation of model neurons, which models the firing rate of real neurons, supervised learning has been thoroughly studied. The famous backpropagation learning rule for this kind of networks is a cornerstone of ▶ connectionist theories of learning. However, the study of supervised learning in spiking neural networks has been hampered, until recently, by the discontinuities generated by spikes, which create difficulties in applying the typical methods for deriving supervised learning rules in artificial neural networks. Important Scientific Research and Open Questions The first supervised learning method for spiking neurons was SpikeProp (Bohte et al. 2002), a method inspired by the backpropagation algorithm used for training classical, non-spiking artificial neural networks. SpikeProp works by minimizing the difference between the timing of an output spike and the desired timing. The method is designed for adjusting just the timing of a single (first) spike per output neuron and assumes that the synapses are such that each output neuron fires at least one spike for the given inputs. The method is not suitable for adjusting the number of output spikes nor for training a network to fire given output spike patterns that extend in time. Pfister et al. (2006) have derived supervised learning rules for probabilistic neurons. The learning method is based on gradient ascent in the space of synaptic efficacies, which maximizes the likelihood of having a trained neuron firing at the desired moments. Because of the probabilistic framework, the learning rules do not involve the actual timing of the output spikes, but the probability of having a particular output spike train given a particular input spike train. The tempotron (Gütig and Sompolinsky 2006) implements supervised learning for a particular task, where an output neuron either fires one spike or does not fire, when presented with an input spike train. The approach assumes that after the neuron emits a spike in response to an input pattern, all other incoming spikes have no effect on the neuron (are shunted), which is artificial. The method requires information that is nonlocal in time, needing to monitor the maximum of the output, and information that is not available to the neuron, such as the maximum of the membrane potential that would have been reached if the neuron would have not fired. The timing of the output spike cannot be controlled with this method. The tempotron has a binary response and, thus, its output cannot distinguish between more than two input categories. All these constraints undermine its biological plausibility and its applicability to more general problems. ReSuMe (Ponulak and Kasiński 2010) is a general supervised learning method for spiking neurons that allows learning of arbitrary output spike trains. However, this learning rule has been conjectured without an analytical justification, by analogy to the Widrow–Hoff rule for analog neurons. To date, it has been shown analytically that ReSuMe will converge to an optimal solution only for the case of one input spike and one target output spike. Simulations have shown that not all the terms of the conjectured learning rule are needed for learning. Florian (2011) introduced two general supervised learning rules for spiking neurons that encode information in the precise timings of spikes, for both input and output (chronotrons). The first rule, E-learning, is analytically derived and much more efficient than ReSuMe, while the second rule, I-learning, has a high degree of biological plausibility. Both learning rules allow neurons to fire spikes at the desired timings, with sub-millisecond precision. Using these rules, chronotrons can learn to classify their inputs, by firing identical, temporally coded spike trains for different inputs belonging to the same class. When the input is noisy, the classification also leads to noise reduction. These rules allowed the computation of the memory capacity of single spiking neurons. I-learning implies that synaptic changes are proportional to the corresponding synaptic currents, being thus biologically plausible. Postsynaptic spikes lead to synaptic depression similar to anti-Hebbian spiketiming-dependent plasticity, while the timings of target postsynaptic spikes trigger potentiation. The depression and potentiation should balance each other when actual spikes occur at the target timings. These target timings could be indicated by spikes coming from other, teacher neurons. The trained neurons’ firing should Supplantation Effect on Learning then become increasingly correlated to the one of teacher neurons, eventually mimicking their firing with a lag corresponding to the delay of the arrival of the teaching spikes. The existence of similar learning rules in the brain remains to be established. Similar mechanisms might be responsible for neural synchronization that modulates neural interactions, such as the synchronization of thalamic neurons needed for driving the cortex through weak synapses; for encoding of information through synchronization; or for the fine temporal tuning of excitation relative to inhibition that contributes to stimulus selectivity in rat somatosensory cortex. Supervised learning rules for spiking neural networks were reviewed by Kasiński and Ponulak (2006).

If a learner is not able to accomplish a mental, covert operation internally and an external representation is able to replace this process, supplantation occurs. External representation supporting supplantation can either be static representations like graphs or dynamic representations like animations or film. The basic function of the external representation is to show a functional link between objects that cannot be constructed by a learner on his or her own. Learners can internalize this link and, thus, reconstruct a relationship between internally represented objects without greater mental effort. Nevertheless, an active cognitive processing is required. Theoretical Background The term and the basic concept of supplantation are derived from the work of Salomon and colleagues in the late 1970s and 1980s. Based on socioconstructivism theories, Salomon (1970, 1979) assumes that symbol systems are not only communicational devices but rather tools for thinking. A basic assumption of supplantation is that media as external representations are related and interact with internal mental operations and representations. The mapping process between external and internal representation depends on the learners’ prior knowledge, because learners have to understand the coding system as well as the objects and their relationships. This does not include that the relation between objects is already known but rather that learners are able to understand this relation. Vogel et al. (2007) describe this process as follows (see Fig. 1): A learner might have an internal S 3248 S Supplantation Effect on Learning External representation Object 1 Transformation1 Subjects’ mind Object 1 Surface OperationExternal Transformation1 OperationSurface Object 2 External External representations Internal Transformation2 Transformation1 Object 2 T2 Object 2 External T2 OperationInternal Object 2 Surface Internal Surface representations Internal representations Supplantation Effect on Learning. Fig. 1 Supplantation of operations representation of two objects (Object 1 and Object 2) but does not have a representation of the operation that links these two objects. The external representation shows this operation. At a first step (Transformation1) a surface representation is built in the learner’s mind. In a second step, an internal representation (Transformation2) is built. This process is not a unidirectional mode of information processing but rather an interactive mapping and schema construction process between external, surface, and internal representations. While Fig. 1 presents a complete process, Salomon (1972) as well as Vogel et al. (2007, p. 1289) single out that several degrees of supplantation are possible: 1. Including the necessary mental activities by showing nothing but the beginning state of a process 2. Presenting the initial situation and its final modification 3. Presenting the initial situation and its transformation but not the final modification 4. Maximal supplantation: presenting the initial situation, its transformation, and the final modification The degree of supplantation varies depending on learners’ aptitudes, especially regarding their prior knowledge and mental skills (i.e., supplantation is a process that underlies an Aptitude-Treatment-Interaction, ATI). For example, Salomon (1979) shows that prior knowledge is necessary for understanding the objects and the transformation that should be supplanted but – on the other hand – might also inhibit the supplantation process; with already fair skill mastery it is more effective to just activate this skill instead of providing complete skill supplantation, because interference processes are likely to occur. With poor initial mastery, learners benefit rather from supplanting codes but not from codes that only aim to activate skills. In general, the process of supplantation remains in the tradition of observational learning transferred to media and, meanwhile, multimedia-based learning environments. Supplantation is compatible with most of recent models of processing information from pictures and text as well as multimedia learning environments like Mayer’s S-O-I-model of multimedia learning or the model of text and picture comprehension by Schnotz and Bannert (cf. Vogel et al. 2007). Important Scientific Research and Open Questions Support for the supplantation hypothesis is provided within several studies. Salomon (1972) used film as media in order to show the effect of supplantation. In several studies, he used different versions of films. Within a supplantation version, an operation between two states was presented by zooming in and out (the material was about the overall impression and details of Breughel’s paintings). In control group versions these operations were shortened by only showing the initial and the final state of an operation. Both of these conditions were compared to an activation condition where learners were presented only the initial state of Surface Approaches to Learning an operation and were required to activate the appropriate mediating operation from their own mental repertoire. Results reveal that the supplantation version and the activation version led to superior results in selecting details out of the presented paintings. There was also a strong ATI-effect showing that poor scorers on cue-attendance (important for singling out details) and verbal reasoning benefited far more from filmic supplantation than learners with high scores in these aptitudes. A subsequent study using a different task (laying out solid objects and folding them back again) compared supplantative vs. short-circuited film and replicated the findings from the prior study. Nevertheless, not only films can be used to achieve supplantation effects. In a study by Seel and Dörr (1994) sets of images integrated in a computer program were used to show different objects as well as their transformations in a supplantation condition (the learning domain was to watch a three-dimensional object and then to imagine the corresponding orthogonal projection and vice versa). This was compared with an imagery condition without the visualization of the transformation. Authors found strong evidence for the supplantation hypothesis stating that showing the operations within both types of visualizations leads to superior task performance than just presenting single object states without the transformation process. Similar results by using a computer program for interpreting data and graphs are reported by Vogel et al. (2007). In a study by Zumbach et al. (2008) authors compared animations – within the domain of eutrophication of lakes – to static versions about the same topic presented as text with pictures. The animations showing dynamically the transition between different states of a lake during the year proved to be more effective in building up a mental model about the process and underlying parameters and their relationship than text and pictures. This also supports the supplantation hypothesis showing that media itself can overtake cognitive functions by supporting knowledge construction through internalizing supplanted operations.

Common-sense psychology conceptualizes surprise as a peculiar state of mind, usually of brief duration, caused by unexpected events of all kinds. Subjectively, surprise manifests itself centrally in a phenomenal experience or “feeling” with a characteristic quality, that can vary in intensity (e.g., one can feel slightly, moderately, or strongly surprised). In addition, the surprised person is often aware of a variety of surprise-related mental and behavioral events: she realizes that something is different from usual or other than expected; she notices that her ongoing mental processes and actions are being interrupted and that her attention is drawn to the unexpected event; she may feel curiosity about the nature and causes of this event; and she may notice the occurrence of spontaneous epistemic search processes. Objectively (i.e., from the perspective of the outside observer), surprise may reveal itself – depending on circumstances – in any of a number of behavioral indicators, including: interruption or delay of ongoing motor activities; orienting of the sense organs to the surprising event; investigative activities such as visual search and questioning others; spontaneous exclamations (“Oh!”) and explicit verbal proclamations of being surprised; and a characteristic facial expression consisting, in full-blown form, of eyebrow-raising, eye-widening, and mouth-opening/jaw drop. Furthermore, psychophysiological studies suggest that surprising events may elicit a variety of bodily changes, commonly subsumed under the so-called orienting response, such as a temporary slowing of heart rate and an increased activity of the eccrine sweat glands. It must be emphasized, however, that the behavioral manifestations of surprise occur by no means in all situations and are in general only loosely associated with one another. Anticipation, surprise, and learning. Many natural, as well as some artificial agents are not (just) reactive but anticipatory in that they are able to generate predictions or expectations of possible future situations and to use these models of the future to optimize their current decisions. To be adaptive, it is essential that an agent’s models of the current and future situations are approximately correct, and this means that these models must, when necessary, be updated to reflect newly acquired information. It is in this context that the surprise mechanism plays an important role. Although surprise is not confined to explicit learning situations, it occurs frequently in such situations, and it plays an important role for both explicit and incidental learning. Surprise occurs in learning situations, for example, when the anticipated effects of an observed event, or an own action, are inconsistent with the feedback from reality. The surprising effects may lead to learning or schema-update (e.g., in changed expectations about the effects of an action). In addition, the agent may actively select those parts of the environment that it expects to be most relevant for learning (see below). Theoretical Background Many natural, as well as some recent artificial cognitive agents are not (purely) reactive but anticipatory. This means that the behaviors of these agents are guided by a model of the environment that includes the possible future development of the current situation. Such a model may also be used to decide which information to focus on, for example, in learning situations. Typically, the states of the world relevant for decision and action are only partly known to agents. Due to the imperfection of their perceptual and sense-making processes, and because it is impossible or too costly to obtain all potentially relevant pieces of information about the world, agents never have complete information about the environment in which they act. According to several psychologists, ethologists, and cognitive scientists, the evolutionary solution to this problem in humans and other animals consisted of the emergence of information-processing mechanisms which generate assumptions or expectations that fill in gaps in the available knowledge (e.g., Piaget 1952; cited in Macedo et al. 2009). Although many of these Surprise and Anticipation in Learning assumptions or expectations concern unknown current states of the world, those most important for action concern possible future situations. The efficacy of an agent’s behavior can therefore be greatly improved if its model of the world includes a good model of the future states of the world. Because future worlds cannot be perceived in any direct sense, natural agents have evolved mechanisms (inference procedures) that allow them to make predictions about future states of the world on the basis of their knowledge or beliefs of the current state of the world. However, relying on assumptions and expectations rather than (only) on perceptions of the current situation comes at a cost: The assumptions and expectations may turn out to be false. Although anticipatory agents cannot completely prevent such prediction errors, they can learn from them by correcting their model of the world, i.e., by updating their schemas or beliefs. To be able to do this, they need to have a mechanism or mechanisms that detect inconsistencies or conflicts between their assumptions and expectations (either of the present state of the world or of future states of the world) and the actual state of the world, as soon as the latter becomes known to them. One such mechanism is surprise (Ortony and Partridge 1987; Meyer et al. 1997). Partly because of its important role in the process of knowledge updating, surprise has long been of interest to philosophers and psychologists, with first theories of surprise dating back as far as Aristotle (about 350 B.C.) (for more details on the history of research on surprise, see Macedo et al. 2009). Within contemporary experimental psychology, aspects of surprise first came to be discussed in the 1960s under the headings of “orienting reaction” and “curiosity and exploration” (Berlyne 1960; cited in Macedo et al. 2009). Surprise as an Perception/ cognition of event Beliefs/ schemas concerning event S independent phenomenon came under study in the 1970s, when evolutionary emotion theorists, referring back to Charles Darwin, proposed that surprise is a basic emotion that serves essential biological functions. One of these functions – surprise as an instigator of epistemic (specifically causal) search and a precondition for learning and cognitive development – came to be particularly emphasized by developmental psychologists (see Charlesworth 1969). In the 1970s and 1980s, this suggestion was taken up by social psychologists interested in everyday causal explanations, who emphasized unexpectedness as a main instigator of causal search (e.g., Weiner 1985; cited in Macedo et al. 2009). Meyer et al. (1997) have tried to integrate the modal views of previous surprise theorists with attributional analyses of reactions to unexpected events within the framework of schema theory (Rumelhart 1984; cited in Macedo et al. 2009). The resulting cognitive-evolutionary model of surprise (Fig. 1) assumes that (ultimately) surprise-eliciting events initiate a fourstep sequence of processes. The first step in this sequence consists of (1) the appraisal of an event as schema-discrepant, or unexpected. If the degree of schema-discrepancy (unexpectedness) exceeds a certain threshold, then (2) ongoing mental processes are interrupted, attention is shifted to the unexpected event, and surprise is experienced. This second step serves to enable and prepare (3) the analysis and evaluation of the unexpected event plus – if this analysis suggests so – (4) immediate reactions to the unexpected event and/or an updating, extension, or revision of the schema or schemas that gave rise to the discrepancy. Ideally, successful schema change (belief update) enables the person to predict and, if possible, to control future occurrences of the schema-discrepant event, to Feeling of surprise about event Appraisal of event as unexpected (schema-discrepant) Analysis and evaluation of event Schema update Interruption of processing/ reallocation of processing resources Surprise and Anticipation in Learning. Fig. 1 The cognitive-evolutionary model of surprise (Meyer et al. 1997) 3251 S 3252 S Surprise and Anticipation in Learning avoid the event if it is negative and uncontrollable, or to ignore the event if it is irrelevant for action. The surprise mechanism is assumed to consist at its core of a device that continuously compares, at an unconscious level of processing, the currently activated cognitive schemas (which may be regarded as constituting the person’s working-memory model of her present situation) with newly acquired information (beliefs). As long as this mechanism registers congruence between schema and input – as long as events conform to expectations – the person’s informal theories are supported by the evidence, and there is hence no need to revise them. Rather, the interpretation of events and the control of action take place largely automatically and without effort. In contrast, if a discrepancy between schema and input is detected, a surprise reaction is elicited: ongoing information processing is interrupted, processing resources are reallocated to the unexpected event, surprise is experienced, and cognitive processes (as well as, possibly, overt actions) aimed at the analysis and evaluation of the unexpected event are initiated. The function of these processes is, on the one hand, to enable and motivate immediate adaptive actions directed at the surprising event (short-term adaptation); and on the other hand, to promote the appropriate revision of the disconfirmed schemas and thereby, future adaptive actions (long-term adaptation). Although the model proposed by Meyer et al. concerns surprise in humans, this or a functionally similar surprise mechanism can be regarded as a crucial component of general intelligence, and hence as an essential component of any anticipatory agent that, like humans, is resource-bounded and operates in an imperfectly known and changing environment. The function of the surprise mechanism in such an agent is the same as in humans: to promote the short- and long-term adaptation to unexpected events (Meyer et al. 1997). And as in humans, this function of surprise entails a close connection of surprise to curiosity and exploration (Berlyne 1960; cited in Macedo et al. 2009), as well as to belief revision and learning (e.g., Charlesworth 1969). Important Scientific Research and Open Questions Beginning in the 1960s, when surprise first came into the focus of experimental psychology, research on surprise has steadily increased and is carried out today by investigators in different subfields of psychology, as well as in computer science. Topics addressed by recent psychological research on surprise are, for example: the relation between surprise intensity and the strength of cognitive schemas; the role of surprise in spontaneous attention capture; the effects of surprise on the hindsight bias; the spontaneous facial expression of surprise; and the role of surprise in advertising (see Macedo et al. 2009). In recent years, several computational models of surprise, including concrete computer implementations, have been developed (see Macedo et al. 2009). The aim of these computational models of surprise – which are in part based on psychological theories and findings on the subject – is on the one hand to simulate surprise in order to advance the understanding of surprise in humans, and on the other hand to provide artificial agents (softbots or robots) with the benefits of a surprise mechanism. This second goal is motivated by the belief that surprise is as relevant for artificial agents as it is for humans (Ortony and Partridge 1987). Of particular interest to these models are the details of the computation of surprise. Although current models already do a reasonably good job in modeling surprise in humans, research on this subject is continuing. This research also has relevance for machine learning. To perform well, current supervised machine learning systems must be trained on hundreds or even thousands of labeled examples. For many learning tasks, these learning instances are difficult, time-consuming, or expensive to obtain. To overcome these problems, so-called active learning paradigms allow the learning algorithm to choose the data from which it learns (Settles 2009). The aim is to select training data that have high information value, allowing to improve performance with less training. This raises the question of how the information value of data should be gauged. One measure of information value frequently used by active learning algorithms is the Shannon entropy. Alternatively, surprise could be used as an index of the relevance of information for learning (Macedo et al. 2009). In this case, the goal is to select data that maximize the intensity of surprise or more precisely, the intensity of expected surprise. For example, consider conducting experiments as learning experiences. If the possible outcomes of an experiment are expected to be unsurprising, the principle of maximizing expected surprise dictates that the experiment should not be Sutherland, Edwin H. (1883–1950) conducted. In contrast, if one anticipates surprise from an experiment, one should conduct it to learn from it. Recent years have also seen an increased interest in the topic of anticipation in artificial systems. Pezzulo et al. (2008) present an overview of this research field that focuses on both the understanding of anticipation in natural agents and its implementation in artificial systems. S Sutherland, Edwin H.

Sutherland, an American sociologist and criminologist, was born at Gibbon, Nebraska, in the USA on 13th August, 1883. He was the third of seven children born to George Sutherland, a clergy/college professor/college president and Lizzie (Pickett) Sutherland. Sutherland’s father had been raised in intensely religious and sober family and he committed to bring his children up in similar ways. The family lived in a rural area, and in that setting, they succeeded in inculcating the sense of moral implications involved in carrying out one’s duties. Snodgrass (1972) has observed that, Sutherland’s father was a religious fundamentalist and followed all austere and strict practices of his Baptist faith in bringing up his children. In 1893 when Sutherland was 10 years, his family moved from Gibbon Nebraska to Grand Island, Nebraska, where young Sutherland attended Grand Island College. Originally, Sutherland studied history, and graduated with bachelor’s in 1904 from Grand Island College where his clergy father, George Sutherland was president (Goff 1982). In 1905, he enrolled in a correspondence course in introductory sociology offered by the home study department of the University of Chicago. At this point in his life, he was planning to do graduate studies in history at the University of Chicago, and a course in sociology was a requirement. It was this university requirement that set Sutherland on the path of reading sociology, and eventually becoming a reputable sociologist and helping to develop one key subfield in sociology – criminology. In 1906, Sutherland began graduate study at the department of sociology, University of Chicago where he changed his major from history to sociology. He was persuaded by his correspondence course instructor to take a course with Henderson who eventually became his graduate studies advisor. Sutherland completed his Ph.D. in Sociology in 1913 with specialization in political economy (Gaylord and Galliher 1988). References Charlesworth, W. R. (1969).

Surprise-Based Learning ▶ Surprise and Anticipation in Learning 3253 S 3254 S Sutherland, Edwin H. (1883–1950) Sutherland had 2 years of predoctoral teaching career and 36 years or so of postdoctoral teaching/ research career. After graduating with bachelor’s degree from Grand Island College in 1904, he was employed by Sioux Falls College in South Dakota where he taught Latin, Greek, history, and shorthand for 2 years. Between 1906 and 1926, Sutherland passed through five academic institutions, namely, the University of Chicago (1906–1913, as a graduate student), William Jewell College (1913–1919, as a professor), University of Kansas (1918, as a visiting scholar of sociology), University of Illinois (1919–26, as an assistant professor of sociology, and later as an associate professor of sociology), and Northwestern University (1922, as a visiting professor of sociology). In 1926, Sutherland was appointed a full professor of sociology at the University of Minnesota, a position he occupied until 1929. Between 1929 and 1930, he worked as a researcher for the New York Bureau of Social Hygiene. From 1930 to 1935, Sutherland was a professor of sociology at the University of Chicago, his alma mater. From the University of Chicago, he moved to the Indiana University to serve as the head of the department of sociology from 1935 to 1949. In 1939, Sutherland was elected the 29th president of the American Sociological Society, and in 1940, president of the Sociological Research Association. Sutherland also became the president of Indiana University’s Institute of Criminal Law and Criminology, president of the American Prison Association, and president of the Chicago Academy of Criminology. He also served as visiting professor of sociology at the University of Washington in 1942, and founded the Bloomington Institute of Criminal Law and Criminology. Contribution(s) to the Field of Learning Sutherland’s contribution to the field of learning is in the area of criminal learning, i.e., how criminals come to acquire the criminal skills with which they operate. This however was not part of his training. In studying for his bachelor’s, Sutherland specialized in history, and in his doctorate in sociology, specialized in political economy. In the early period of his teaching/research career therefore, Sutherland focused on these specialties – history at Sioux Falls College, and political economy after his doctorate until the early 1920s. It was during his tenure at the University of Illinois between 1919 and1926 that Sutherland’s work in the area of crime became evident and eventually his contribution to the field of learning science. In 1921, Sutherland received a proposal from the head of sociology department at the University of Illinois to write a textbook on criminology. At that time, this proposal seemed odd, but turned out to be a fortuitous endeavor. Sutherland had only taught criminology occasionally and he had no publications in criminology. However, his book, Criminology, was duly published in 1924 and retitled Principles of Criminology in 1934. In 1932, Sutherland met Broadway Jones, a Chicago-based renowned grifter who regaled Sutherland with narratives of his remarkable exploits in the criminal underworld. Excited by these stories, Sutherland and Jones started compiling these stories with the hope of publishing them one day. Eventually in 1937, Sutherland and Jones published these narratives as the Professional Thief (in which Jones used the pseudonym “Chic Conwell”). From the stories of Jones, Sutherland became convinced that professional criminals learn the techniques and attitudes involved in professional criminal work from close association with other professional criminals. This simple notion compelled Sutherland to start theorizing in the third edition of his Criminology (1939, pp. 4–8) that crime is a function of differential association, i.e., the different interactions/associations and patterns of learning that take place in groups such as juvenile gangs. In 1947 when the fourth edition of Sutherland’s Criminology (the Principles of Criminology) appeared, he had outlined clearly differential association theory, his most renowned export into the criminological world. This theory contained nine principles suggesting that criminal behavior is learned in a process of communication in intimate personal groups. These groups, according to the theory, teach skills, motivations, attitudes, and rationalizations, as well as definitions either favorable or unfavorable to the violation of the criminal law. The principles of differential association theory are as follows: 1. Criminal behavior is learned; it is not inherited. 2. Criminal behavior is learned in interaction with other people in the process of communication. 3. The principal part of learning criminal behavior occurs in intimate groups. Syllogistic Reasoning 4. When criminal behavior is learned, the learning includes (a) techniques, sometimes complicated, and sometimes very simple and (b) the specific direction of motives, drives, rationalizations, and attitudes. 5. The specific direction of motives and drives are learned from definitions of legal codes as favorable or unfavorable. 6. A person becomes criminal because of excess of definitions favorable to the violation of law over definitions unfavorable to the violation of law. 7. Differential association varies in frequency, duration, priority, and intensity. 8. The process of learning criminal behavior involves the same mechanisms involved in any other learning process. 9. Both criminal and noncriminal behaviors are expressions of the same needs and values. The basic premise of the differential association theory is that criminal behavior results when one is exposed to an excess of definitions favorable to the violation of the law over those unfavorable through interactions with others. With this theory, Sutherland rejected the notions of criminal behavior being caused by psychopathological or economic factors, the leading explanations of crime causation before the 1930s. Sutherland’s Criminology (Principles of Criminology) was published in four editions – 1924, 1934, 1939, and 1947 before his death in 1950, and has since been kept in print, first by Donald Cressey and later by David Luckenbill. The Eleventh edition of the book appeared in 1992. Sutherland also has contributed more than 50 articles to journals and books dealing with different aspects of the learning process for the acquisition of criminal skills. Important Scientific Research and Open Questions At the time Sutherland died in 1950, in Bloomington, Indiana, it was said that, it had become a colloquialism to refer to him as the dean of American criminology. He is considered one of the most influential criminologists of the twentieth century and is most remembered for the conceptual and theoretical contributions he made to the field of criminal studies, particularly the learning process in his differential association theory. His legacy straddles across teaching and research. A number of S 3255 Sutherland’s graduate students (including Donald Cressey, Lloyd Ohlin, Albert Cohen, and Karl Schuessler) also became equally influential personalities in the field of criminology helping to shed more light on Sutherland’s work. Recognizing the contribution of Sutherland to the field of criminology and to the learning aspect of criminological science, the American Society of Criminology in 1960, established an annual award that carries Sutherland’s name – The Sutherland Award. This award, the most prestigious recognition for an American criminologist, is given to scholars recognized to have made outstanding contributions to theory or research in criminology, to the etiology of criminal and deviance behavior, and to the criminal justice system, corrections, law, or justice. Daniel Glaser, Albert Cohen, Robert Merton, Charles Tittle, and Lloyd Ohlin are among the leading criminologists who have won the Sutherland award. He has also been the subject of several Ph.D. dissertations including Snodgrass in 1972 and Goff in 1982.

A syllogism (Greek: sullοgismός – “conclusion,” “inference”) or logical appeal is a kind of logical argument in which S 3256 S Symbol Systems one proposition (the conclusion) is inferred from two others (the premises) of a certain form. Although there are infinitely many possible syllogisms, there are only a finite number of logically distinct types. Symbol Systems The form of symbolic expression used to communicate ideas such as spoken language, printed text, music, numbers, images, graphs, photographs, and so forth. Symbols Arbitrary signs that have acquired a conventional significance. Synaesthesia This is a neurologically based condition in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. In one common form, known as grapheme-color synaesthesia, letters or numbers are perceived as inherently colored.

Synthetic Learning Environment PATRICK BLUMSCHEIN Department of School Education, University of Education, Freiburg, Germany Synthetic learning environments can be characterized in terms of a particular technology (e.g., a simulation Systemic Therapy or game), subject matter, learner characteristics, and some guiding pedagogical principles (Cannon-Bowers and Bowers 2008). In many cases, synthetic learning environments involve a computer simulation as a central component and thus serve as simulationbased training. As Cannon-Bowers and Bowers (2008) point out, synthetic learning environments can be developed in countless ways and many variables must be taken into account. Therefore, engineering a synthetic learning environment places great demands on the instructional design. Cannon-Bowers and Bowers focus on several instructional features and strategies, such as authenticity and fidelity of learning experiences, model-based reasoning, the design of cases or scenarios that provide the context for instruction, and collaborative and social learning as well as various motivational factors (e.g., goal setting, engagement, reinforcement).

S 3257 System Dynamics System dynamics is an approach to modeling the dynamics of systems which interact strongly with each other. System dynamics was founded in the early 1960s by Jay W. Forrester of the MIT Sloan School of Management. System dynamics refers to studying complex systems by applying feedback loops. Stocks and flows are the basic building blocks of system dynamic models. They help describe how a system is connected by feedback loops which create the nonlinearity found so frequently in modern day problems. Computer software is used to simulate a system dynamics model of the situation being studied. Running “what if” simulations to test certain policies on such a model can greatly aid in understanding how the system changes over time. System Simulation Model ▶ Computer Simulation Model Systematic Repetition System In the strongest case, a system refers to an information processor that can be differentiated from other information processors on the basis of psychological process, the computational algorithms, and the underlying neural substrates. The constituents of a system are a set of elements which are interconnected to aid in driving toward a desired goal. This definition has two implications: First, a system consists of elements (parts) that are interconnected through relationships or functions. The number and quality of these relationships determine that a system can range from simple to complex. The central goal of creating a “valid” model of a system is to capture the most important elements and especially the nature of the relationships. Second, the goal orientation of a system implies its continuous improvement. Feedback from the system must be used to measure the performance of the system against its desired goal. ▶ Drill and Practice in Learning (and Beyond) Systemic Functional Linguistics Also known as SFL, is a branch of linguistic focusing on language in use and looking on portions of discourse larger than the sentence. Founded by Michael Halliday in the 1960s, SFL is grounded in the view of language as “a network of systems, or interrelated sets of options for making meaning.” The term “functional” indicates that the approach is concerned with the contextualized, practical uses to which language is put.
