Learning, Memory & Perception

← Back to Domain-Specific Families

Abstractions about acquiring, retaining, retrieving, and interpreting information in cognitive systems. They span conditioning and perceptual learning, memory states and tests, cognitive development, language processing, subjective validation, attention, and experience-dependent adaptation.

31 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Attenuation theory — A selective-attention model in which unattended inputs are weakened rather than completely blocked, allowing sufficiently salient or low-threshold content to reach awareness.
• Benton Visual Retention Test — An individually administered standardized test in which a person reproduces geometric designs from immediate or delayed exposure, yielding scored evidence about visual perception, visuoconstruction and visual memory.
• Bi-directional hypothesis of language and action — The embodied-cognition hypothesis that language comprehension and sensorimotor activity influence one another reciprocally.
• Categorical perception — A perceptual phenomenon in which continuous stimulus variation is experienced or discriminated as discrete categories, with enhanced sensitivity near category boundaries.
• Classical conditioning — Learning in which a previously neutral cue acquires the capacity to elicit a response after predictive pairing with a biologically or motivationally significant event.
• Cognitive development — The age- and experience-related transformation of perception, memory, language, reasoning, conceptual understanding and executive control across childhood and beyond.
• Cognitive interview — A structured forensic-interview method that uses context reinstatement, varied retrieval and witness-centered reporting to improve recall while limiting suggestion.
• Conceptual system — An organized network of concepts and relations through which a person or community represents and interprets a domain.
• Descriptive Experience Sampling — An introspective research method that samples immediately preceding inner experience at randomly signaled moments and refines descriptions through iterative interviews.
• Echoic memory — A brief high-capacity auditory sensory store that preserves a fading trace of recently heard information for perceptual integration.
• Equipotentiality — Represent Lashley's historical hypothesis that, within a relevant functional cortical area and task class, intact portions can assume functions lost when other portions are damaged, often with reduced efficiency.
• Forward testing effect — Improved learning of new material caused by retrieving earlier material between study segments.
• Information processing theory — A cognitive-development perspective that models perception, attention, memory, strategy and response as coordinated stages or resources whose capacity, speed and organization change with development.
• Law of effect — The learning principle that responses followed by satisfying consequences become more likely in the same situation, while responses followed by discomfort become less likely.
• Memorization — The deliberate encoding and consolidation of information so it can later be reproduced or recognized from memory.
• Microtraining — A short structured workplace-learning format that activates informal knowledge exchange in sessions of roughly fifteen to twenty minutes.
• Mood-dependent memory — Improved retrieval when a person’s mood at recall matches the mood present during encoding.
• Multiple trace theory — A memory theory proposing that each encoding or retrieval event creates a partly distinct trace and that remembering depends on their combined overlap rather than strengthening one stored token.
• Narrative bias — A cognitive tendency to privilege coherent stories over complex, statistical, fragmented, or causally unrelated information.
• Neuronal recycling hypothesis — Explain culturally recent capacities as constrained reuses of older cortical circuits whose inherited organization supplies a compatible neuronal niche and is partially reshaped through learning.
• Next-in-line effect — A memory impairment for information presented immediately before one's anticipated turn to perform, attributed to self-focused preparation and anxiety.
• Number sense in animals — The capacity of nonhuman animals to represent, compare, or discriminate quantities numerically.
• Perceptual learning — Experience-dependent, relatively durable improvement in extracting or discriminating sensory information through practice or exposure.
• Pollyanna principle — A positivity bias favoring pleasant information in memory, attention or judgment under specified conditions.
• Reminiscence — The voluntary or cue-evoked recollection and often social narration of personally experienced past events, commonly integrating memory, identity, emotion, and relationship.
• Ribot's law — The historical temporal-gradient hypothesis that retrograde amnesia preferentially impairs recently formed memories while relatively sparing older, more consolidated memories.
• State-dependent memory — Improved retrieval when an individual’s internal physiological, affective, or cognitive state matches the state present during encoding.
• Statistical learning in language acquisition — The extraction of distributional regularities from speech or language input, such as transitional probabilities, to discover word boundaries, categories and structural patterns.
• Subjective validation — The bias of judging a vague, coincidental or unsupported statement as accurate because it feels personally meaningful or confirms existing beliefs.
• U-shaped development — A nonmonotonic learning or developmental trajectory in which initially successful performance declines during reorganization and later recovers at a more systematic or advanced level.
• Visual short-term memory — A capacity-limited temporary store that maintains visual representations for seconds after fragile iconic persistence has faded, supporting comparison and ongoing visual cognition without long-term retention.
