All behaviors in Memory Phenomena
Anterograde Amnesia
The inability to form new long-term memories after an injury, illness, or condition — the system can experience the present but cannot deposit it as autobiographical material.
Autobiographical Memory
The integrated personal record of the life one has lived — episodes, themes, and self-knowledge organised around the continuing question of who you are.
Body Memory
The somatic encoding of experience — postural, muscular, autonomic, and visceral — that holds skill, conditioning, and unresolved arousal in the tissues and reflexes of the body itself, often persisting long after the events that taught the body what to hold.
Childhood Amnesia
The near-universal absence of episodic memories from the first three to four years of life — the developmental window during which the body lived fully but did not yet have the architecture to deposit autobiographical scenes.
Cryptomnesia
Recalling something you previously encoded as if it were original to you — unconscious plagiarism — where a phrase, melody, or idea returns to consciousness wearing the felt signature of *I just thought of this* even though the system encountered it months or years ago.
Deja Vu
A sudden, unwarranted sense that the present moment has already been lived — a familiarity signal that arrives without an identifiable memory source, often pointing at meaning the system half-recognises but cannot place.
Echoic Memory
The three-to-four-second auditory after-trace the brain holds in place after a sound has stopped, giving the listener time to decide what was said before the words have fully arrived in conscious comprehension.
Encoding Specificity
The principle that retrieval is most successful when the cues present at recall match the cues present at the original encoding — meaning is stored together with its context, and the context becomes part of the key.
Episodic Memory
The capacity to mentally re-experience specific past events — to travel back, in a small way, to a particular when and where with yourself inside it.
False Memories
Memories that feel real, detailed, and emotionally vivid, but do not match the event the system thinks it is remembering — a reconstruction the brain has assembled, often coherently, out of fragments, suggestions, and the demand for narrative.
Flashbulb Memory
The vivid, confidently-held memory of where you were and what you were doing when you heard of a significant, often shocking event — felt as photographic but more reconstructed than the confidence suggests.
Forgetting Curve
The predictable, steep early decay of newly encoded information unless the system meets it again — the body's default response to a deposit that never received a second pass.
Iconic Memory
The fraction-of-a-second visual after-image the brain holds in place between the moment light hits the retina and the moment perception consciously resolves, giving the rest of the cognitive system just enough time to decide what the eye actually saw.
Implicit Memory
The memory system that shapes present behaviour, perception, and preference without conscious recollection — the long, quiet substrate of skill, priming, association, and habit that the self runs on without remembering it learned to.
Jamais Vu
The sudden alienation of something thoroughly known — a familiar word, face, or room briefly losing its familiarity and becoming uncanny, as if seen for the first time.
Memory Consolidation
The slow, mostly invisible process by which a fresh experience gets stabilised, integrated, and re-organised across brain systems — moving from a fragile hippocampal trace toward durable, neocortically distributed memory.
Memory Reconsolidation
The neurobiological window in which a retrieved memory becomes briefly malleable and is re-written into storage — meaning every act of remembering is also an act of revising.
Memory Self-Editing
The continuous, mostly unconscious revision of one's autobiographical record — selecting, smoothing, and re-shaping past events so they align with who one currently believes one is, or with who one would prefer to have been.
Misinformation Effect
The systematic overwriting of an encoded memory by information that arrives after the event — a leading question, a follow-up news report, a confident witness — such that the post-event detail comes to feel like part of the original experience.
Mood-Congruent Memory
The tendency of memory to selectively retrieve material whose emotional tone matches your current mood — so sad states recall sad memories, anxious states recall threats, and the present mood gets confirmed by an apparently representative past.
Presque Vu
The vivid sense that something deeply meaningful is about to be remembered or understood — a felt imminence of insight that hovers at the edge of consciousness without arriving.
Procedural Memory
The slow, mostly silent encoding of skill into the body — bicycling, typing, driving, the unconscious grammar of your native language — where the deposit is invisible for a long time and then arrives all at once as a competence you cannot easily explain.
Recovered Memories
Memories of past events — often early or distressing — that re-emerge into conscious awareness after a long period of inaccessibility, by a process that ranges from genuine integration of a buried trace to suggestion-shaped reconstruction, and that requires careful, humble handling on either side of the line.
Reminiscence Bump
The disproportionate density of autobiographical memories from roughly ages ten to thirty — the period during which the self was being assembled and which the rest of life keeps returning to as if to first ground.
Retrograde Amnesia
The loss of access to memories formed before an injury, illness, or psychological event — a structural break in the system's connection to its own prior deposits.
Semantic Memory
The store of integrated general knowledge — facts, concepts, meanings of words, and stable truths about the world that no longer carry the scene of their original learning.
Source Confusion
Remembering a fact, image, or statement clearly while losing track of where it came from — was it a friend, an article, a dream, a film, your own imagining — such that the content is preserved but its origin is mis-attributed or lost entirely.
State-Dependent Memory
The tendency of memory to retrieve more reliably when the internal state at retrieval matches the internal state at encoding — so a thought formed when tired comes back more easily when tired, and what was learned drunk is partially lost when sober.
Suppressed Memories
Memories that remain accessible in principle but are actively kept from retrieval — pushed below the working surface by a system that has decided, often without conscious deliberation, that contacting them now is not worth the cost.
Tip-of-the-Tongue Phenomenon
The state of being unable to retrieve a specific word or name you plainly know — with partial features available (first letter, rhythm, length, register) but the word itself out of reach.
Trauma Memory Fragmentation
The way overwhelming events are encoded in pieces — bodily sensations, images, sounds, fragments — rather than as a coherent narrative the self can carry, because the systems that usually weave experience together were too taxed at the time of encoding to weave.
Working Memory
The small, fragile workspace that holds the few items you are actively thinking with right now — phone number, half-finished sentence, mental arithmetic — where the effort of holding is large, the deposit is whatever you do with the held material, and overload produces real felt fatigue with nothing to show for it.
