A

Abstract schema (Ch. 11, Section 11.3): A generalized knowledge structure that captures the deep, structural features of a problem or concept category, stripped of surface details. Abstract schemas enable transfer by allowing learners to recognize structural similarities across superficially different problems. See also: near transfer, far transfer, structural similarity.

Active listening (Ch. 20, Section 20.1): A deliberate, effortful approach to processing spoken or audio information that involves questioning, summarizing, and connecting material rather than passively receiving it. See also: lecture illusion, pause-process technique.

Self-regulated learning cycle (Ch. 14, Section 14.5): Zimmerman's three-phase model of self-regulated learning: forethought (planning and goal-setting), performance (monitoring and strategy use during study), and reflection (evaluating results and adjusting for next time). See also: Zimmerman's SRL model, metacognitive monitoring, metacognitive control.

Self-testing (Ch. 16, Section 16.1): Any activity in which the learner tests their own knowledge without external prompting, including flashcard review, brain dumps, practice quizzes, and retrieval grids. Functions both as a learning strategy and a metacognitive monitoring tool. See also: retrieval practice, practice testing, testing effect.

Semantic encoding (Ch. 12, Section 12.2): Encoding that focuses on the meaning and significance of information. The deepest level of processing, producing the strongest and most durable memories. See also: structural encoding, phonemic encoding, deep processing.

Sensory memory (Ch. 2, Section 2.2): An ultra-brief holding area for raw sensory input, lasting approximately 0.5 seconds for visual information and 3-4 seconds for auditory information. Only information that receives attention passes from sensory memory to working memory. See also: working memory, long-term memory.

Shallow processing (Ch. 12, Section 12.1): Encoding that focuses on the surface features of information (appearance, sound, format) rather than meaning. Produces weak, short-lived memories. See also: deep processing, structural encoding, levels of processing.

Simulation (Ch. 21, Section 21.3): An artificial environment or scenario designed to approximate real-world conditions, allowing learners to practice skills and make mistakes without real-world consequences. See also: problem-based learning, productive failure.

Sketch-noting (Ch. 9, Section 9.3): A visual note-taking technique combining hand-drawn images, diagrams, and text. A form of dual coding that requires the learner to process and transform information. Artistic quality is irrelevant; processing depth is what matters. See also: dual coding theory, mind mapping.

Skimming vs. scanning (Ch. 19, Section 19.4): Two distinct rapid reading strategies. Skimming involves reading quickly to get the gist; scanning involves searching for specific information. Both have appropriate uses but neither constitutes deep reading. See also: reading purpose, SQ3R.

Sleep architecture (Ch. 6, Section 6.2): The structure and cyclical pattern of sleep stages across a night, including alternations between slow-wave sleep and REM sleep. Each cycle lasts approximately 90 minutes, with slow-wave sleep predominating in the first half of the night and REM sleep in the second half. See also: slow-wave sleep, REM sleep, memory consolidation.

Slow-wave sleep (Ch. 6, Section 6.2): Deep sleep characterized by slow, synchronized neural oscillations. Critical for the consolidation of declarative (factual) memories. Predominates in the first half of the night. See also: REM sleep, sleep architecture, memory consolidation.

SMART goals (Ch. 14, Section 14.2): Goals that are Specific, Measurable, Achievable, Relevant, and Time-bound. More effective for learning than vague aspirations because they provide clear criteria for success and enable metacognitive monitoring. See also: study cycle, planning fallacy.

Social identity threat (Ch. 18, Section 18.3): The experience of being in a situation where negative stereotypes about one's group could apply, creating anxiety and consuming cognitive resources. A broader category that includes stereotype threat. See also: stereotype threat, belonging uncertainty.

Split-attention effect (Ch. 5, Section 5.5): The increase in extraneous cognitive load that occurs when learners must mentally integrate information from two physically or temporally separated sources. Reduced by integrating sources (e.g., labeling diagrams directly rather than using a separate legend). See also: extraneous load, redundancy effect, modality effect.

SQ3R (Ch. 19, Section 19.1): A reading strategy framework: Survey, Question, Read, Recite, Review. Developed by Francis Pleasant Robinson in 1946. Remains useful but is enhanced by modern updates that emphasize retrieval practice. See also: PQ4R, metacomprehension.

State-dependent memory (Ch. 2, Section 2.5): The finding that memories are more accessible when the learner's internal state at retrieval matches the state at encoding. Related to encoding specificity but specific to internal states (mood, arousal, substance use). See also: encoding specificity principle.

Stereotype threat (Ch. 18, Section 18.2): The situational anxiety experienced when a person is at risk of confirming a negative stereotype about their group. Can impair performance on tests and learning tasks by consuming working memory resources. See also: belonging uncertainty, social identity threat.

Storage (Ch. 2, Section 2.1): The second stage of the memory process, in which encoded information is maintained over time. Most study failures are not storage failures; they are encoding or retrieval failures. See also: encoding, retrieval, consolidation.

Storage strength (Ch. 10, Section 10.2): In Bjork's theory of disuse, the depth and durability of a memory trace, reflecting the richness of encoding and the number of connections to other knowledge. High storage strength means the information is well-encoded, but it may still have low retrieval strength if it hasn't been accessed recently. See also: retrieval strength, desirable difficulty.

Structural encoding (Ch. 12, Section 12.2): The shallowest level of processing, focusing on the physical or visual features of information (typeface, color, position on page). Produces the weakest memories. See also: phonemic encoding, semantic encoding, shallow processing.

Study cycle (Ch. 14, Section 14.1): A five-phase approach to studying: preview, attend, review, study, and assess. Each phase serves a distinct function and the cycle repeats throughout a course. See also: preview, active recall, SMART goals.

Summarization strategies (Ch. 19, Section 19.3): Techniques for condensing material into concise, accurate summaries that capture main ideas and their relationships. Most effective when the learner generates summaries from memory rather than while looking at the source. See also: retrieval practice, elaboration.

Surface similarity (Ch. 11, Section 11.2): Superficial features that two problems or situations share (e.g., both involve water, both are set in a hospital). Novices tend to focus on surface similarity when attempting transfer; experts focus on structural similarity. See also: structural similarity, isomorphic problems.

Sustained attention (Ch. 4, Section 4.4): The ability to maintain focus on a single task over an extended period. Biologically limited in most people to approximately 10-20 minutes before lapses become significant. See also: selective attention, mind-wandering, Pomodoro technique.

Synaptic homeostasis (Ch. 6, Section 6.2): A theory proposing that sleep serves to scale down overall synaptic strength that has increased during waking hours, preserving signal-to-noise ratio in neural circuits and making room for new learning. See also: memory consolidation, slow-wave sleep.

System audit (Ch. 28, Section 28.3): A structured quarterly review of your Learning Operating System that evaluates what strategies are working, what has broken down, and what needs adjustment. Applies metacognitive monitoring at the system level. See also: continuous improvement, learning operating system, meta-metacognition.

T

Talent vs. practice debate (Ch. 25, Section 25.2): The ongoing scientific discussion about the relative contributions of innate ability and deliberate practice to expert performance. Current evidence suggests both matter, but the popular "10,000 hours" claim oversimplifies the relationship. See also: 10,000 hours, deliberate practice.

Task switching cost (Ch. 4, Section 4.3): The measurable loss of time, accuracy, and cognitive efficiency that occurs when switching attention from one task to another. Caused by goal shifting and rule activation. Explains why "multitasking" degrades learning. See also: attention residue, divided attention.

Task value (Ch. 17, Section 17.3): In expectancy-value theory, the subjective importance, interest, or utility of a task. Includes intrinsic value (enjoyment), attainment value (importance to identity), utility value (usefulness for goals), and cost (what you give up). See also: expectancy-value theory, self-efficacy.

Temptation bundling (Ch. 17, Section 17.5): A motivational strategy that pairs an activity you need to do (studying) with an activity you want to do (listening to a favorite podcast), so that the enjoyable activity is only available during the necessary one. See also: Premack principle, implementation intention.

Temporal discounting (Ch. 17, Section 17.4): The cognitive tendency to value immediate rewards more heavily than future rewards. Explains why the immediate relief of avoiding a study session outweighs the distant reward of a good grade. See also: temporal motivation theory, procrastination.

Temporal motivation theory (Ch. 17, Section 17.4): A comprehensive model of procrastination that combines expectancy, value, delay, and impulsiveness into a single equation predicting when people will act on or delay a task. See also: temporal discounting, procrastination, expectancy-value theory.

10,000 hours (Ch. 25, Section 25.2): A widely cited but frequently misunderstood estimate of the time required to achieve expert-level performance, popularized by Malcolm Gladwell's interpretation of Anders Ericsson's research. The actual finding is more nuanced: the hours must be deliberate practice, the number varies by domain, and talent and other factors also contribute. See also: deliberate practice, talent vs. practice debate.

Test anxiety (Ch. 23, Section 23.2): A condition characterized by excessive worry, physiological arousal, and cognitive interference before and during exams. Best managed through arousal reappraisal, retrieval-based preparation, and practice testing under exam conditions. See also: arousal reappraisal, practice testing under test conditions.

Test-taking strategies (Ch. 23, Section 23.4): Techniques for navigating exam questions effectively, including time allocation, reading questions carefully, and process of elimination. Most effective when built on a foundation of deep content knowledge. See also: process of elimination, retrieval-based test preparation.

Testing effect (Ch. 2, Section 2.6; Ch. 7, Section 7.2): One of the most robust findings in cognitive psychology: retrieving information from memory strengthens that memory more effectively than re-studying the same information. Taking a test is not just a measurement of learning; it is a powerful cause of learning. See also: retrieval practice, reconsolidation, self-testing.

Text structure awareness (Ch. 19, Section 19.4): Knowledge of how different types of texts are organized (narrative, expository, argumentative, procedural) and the ability to use that structure to guide comprehension and retrieval. See also: reading purpose, SQ3R.

Think-pair-share (Ch. 22, Section 22.3): A cooperative learning strategy in which students first think about a question individually, then discuss with a partner, then share with the larger group. Ensures individual processing before group discussion. See also: peer instruction, collaborative learning.

Time blocking (Ch. 14, Section 14.4): A scheduling technique in which specific blocks of time are dedicated to specific tasks, making study commitments explicit and reducing decision fatigue. See also: Pomodoro technique, planning fallacy.

Tip-of-the-tongue (TOT) (Ch. 13, Section 13.2): The metacognitive experience of knowing that you know something but being temporarily unable to retrieve it. A strong feeling of knowing that is typically accurate — you really do know the information. See also: feeling of knowing, retrieval failure.

Transactive memory (Ch. 22, Section 22.4): The shared system by which groups distribute the cognitive labor of remembering different types of information across different members. Each person knows what the others know and where to find information within the group. See also: social metacognition, collaborative learning.

U

Undesirable difficulty (Ch. 10, Section 10.5): A challenge during learning that is so severe, poorly matched, or confusing that it impairs learning rather than enhancing it. The critical distinction: a difficulty is undesirable when the learner lacks the background knowledge or skills to benefit from the struggle. See also: desirable difficulty, productive failure.

Underconfidence (Ch. 15, Section 15.1): A calibration bias in which learners rate their knowledge or predicted performance lower than their actual knowledge or performance warrants. More common on easy items (hard-easy effect) and in high-performing students. See also: overconfidence, calibration, hard-easy effect.

Utility-value intervention (Ch. 18, Section 18.4): An intervention that helps learners connect academic material to their personal goals, interests, and lives, thereby increasing the perceived value of the task. See also: wise interventions, task value.

V

VAK model (Ch. 8, Section 8.1): The specific learning styles framework categorizing learners as Visual, Auditory, or Kinesthetic. Widely taught in teacher training but not supported by evidence when tested as a guide for instructional matching. See also: learning styles, meshing hypothesis.

Values affirmation (Ch. 18, Section 18.4): A brief intervention in which students write about their core personal values. Has been shown to reduce the performance gap associated with stereotype threat and belonging uncertainty, particularly for underrepresented groups. See also: wise interventions, stereotype threat.

Variation of practice (Ch. 10, Section 10.4): Deliberately varying the conditions, contexts, or parameters of practice rather than repeating the identical task. Produces contextual interference that impairs short-term performance but enhances long-term learning and transfer. See also: contextual interference, interleaving, desirable difficulty.

Verbal system (Ch. 9, Section 9.1): In Paivio's dual coding theory, the cognitive subsystem that processes and stores information in linguistic form (words, sentences, propositions). Works in parallel with the imagery system. See also: dual coding theory, imagery system, referential connections.

Verbatim transcription trap (Ch. 20, Section 20.3): The counterproductive habit of trying to write down everything a lecturer says word-for-word, which engages shallow, structural processing and prevents deeper engagement with meaning. See also: note-taking vs. note-making, generative note-taking.

Video pacing (Ch. 20, Section 20.4): The strategic control of playback speed and pausing when learning from video content. Pausing to process, rewinding to review, and watching at normal speed for new material are more effective than watching at high speed without pauses. See also: pause-process technique, lecture illusion.

Visual analogy (Ch. 9, Section 9.4): A dual coding technique in which an abstract concept is mapped onto a concrete, visual image (e.g., working memory as a "small desk"). Effective because it creates referential connections between verbal and visual codes. See also: dual coding theory, concrete examples.

W

Weekly review (Ch. 14, Section 14.5): A regularly scheduled session (typically 30-60 minutes) in which the learner reviews the past week's learning, updates study plans, and assesses progress toward goals. A critical component of the self-regulated learning cycle. See also: study cycle, self-regulated learning cycle.

Wise interventions (Ch. 18, Section 18.4): Brief, psychologically precise interventions that target specific beliefs or experiences (such as belonging uncertainty or fixed-mindset attributions) to produce lasting improvements in academic outcomes. Include values affirmation, attributional retraining, and utility-value interventions. See also: values affirmation, attributional retraining, utility-value intervention.

Working memory (Ch. 2, Section 2.2): The limited-capacity "workspace" where active, conscious thinking occurs. Can hold approximately four items for approximately 20-30 seconds without rehearsal. The bottleneck through which all new learning must pass. See also: working memory capacity, cognitive load, sensory memory, long-term memory.

Working memory capacity (Ch. 5, Section 5.1): The functional limit of working memory, approximately four items (revised downward from Miller's classic 7 plus or minus 2). This capacity constraint is the foundation of cognitive load theory. See also: working memory, chunking, cognitive load.

Z

Zettelkasten (Ch. 27, Section 27.4): A personal knowledge management method developed by sociologist Niklas Luhmann, using interconnected atomic notes organized by links rather than categories. Designed for lifelong accumulation and connection of ideas. See also: evergreen notes, personal knowledge management, second brain.
