01 / Definition Term

= Mind — integrated system of: perception, attention, memory, reasoning, emotion, language, consciousness

= NOT identical to brain — mind = brain + body + environment (extended)

= substrate: ~86 billion neurons, ~100 trillion synapses

02 / Subsystems Architecture

Perception & Attention

= Perception — input: senses → pattern recognition

= Attention — filter: selects what enters processing

! finite resource: ~4 items in active focus

Memory

= Working Memory — workbench: active manipulation

* the "RAM" of cognition; bottleneck for everything

= Long-term Memory — archive: unlimited, reconstructive

* see: memory (detailed architecture)

Higher Functions

= Reasoning — computation: logic, analogy, abstraction

= Language — encoding: thought → symbols → communication

= Emotion — valuation: assigns meaning and urgency

= Consciousness — integration: unified subjective experience

? "hard problem": why is there subjective experience at all?

03 / Mind as Extended System Theory

. not confined to skull (Clark & Chalmers, 1998)

. tools ARE cognition: pen, notation, CLN, AI

. psychotechture: designing the external part of the mind

* "the mind is what the brain DOES" — Marvin Minsky

04 / Mind vs AI Comparison

+ mind: embodied, emotional, continuous, mortal, conscious

= AI: disembodied, statistical, session-based, replaceable, unconscious

? convergence point: will AI develop subjective experience?

! current risk: humans atrophying the mind they have (ai-amnesia)

05 / Nourishment Practice

Physical

. sleep, exercise, omega-3, borage oil

Cognitive

. structuring, learning, creating (cln-memorization)

Social

. dialogue, teaching, collaborative reasoning

@ see: memory, psychotechture, ai, saccade
