01 / Definition Term

= Memory — cognitive system: encoding → storage → retrieval of information

= not a single system — a family of interacting subsystems

= not a recording — a reconstruction (each recall is a re-creation)

02 / Architecture Structure

Sensory Memory (0.25–3 sec)

= Sensory Memory — raw input buffer: iconic (visual), echoic (auditory)

* most is discarded; attention selects what passes through

Working Memory (seconds, ~4 items)

= Working Memory — active manipulation of information

. bottleneck: limited capacity → chunking is essential

. Baddeley model: phonological loop + visuospatial sketchpad + central executive

Long-term Memory (unlimited, permanent potential)

= Declarative — explicit, conscious

. episodic: personal events ("my first day at work")

. semantic: facts and concepts ("Paris is capital of France")

= Procedural — implicit, automatic

* riding a bike, typing, language grammar

03 / Encoding Depth Craik & Lockhart, 1972

- shallow: physical features (font, color) → weakest trace

. intermediate: phonological (sound, rhythm) → moderate

+ deep: semantic (meaning, type, relation) → strongest trace

+ deepest: self-referential ("how does this affect ME?")

* CLN-memorization operates at semantic depth: typing each fact forces classification

04 / Threats Risks

- digital amnesia: outsourcing recall to devices

- AI amnesia: outsourcing reasoning to LLMs

- sleep deprivation: blocks memory consolidation

- chronic stress: cortisol damages hippocampus

- omega-3 deficiency: impairs neural membrane function

05 / Enhancement Practice

+ active recall > passive review

+ spaced repetition (expanding intervals)

+ chunking — reduce load on working memory

+ mind palace — spatial encoding for sequences

+ CLN structuring — semantic encoding through classification

+ sleep, exercise, omega-3, borage oil
