Computationalism

  • vs Connectionism
  • Collection of theories about mind
  • Theories of representation

(model of the world)

  • Theories of perception

(mental model)

  • Theories of action

(execution of plan)

Dissociation

  • Mind vs world
  • Mental activity vs perception
  • Plans vs behavior
  • The mind vs the body
  • Abstract ideals vs concrete things
slide-4
SLIDE 4

Mind vs World

  • Mind - “container” metaphor, Lakoff

and Johnson (1980)

  • World - hard to maintain accurate

knowledge

  • World model – covertly conflated
  • Research “domain”

SLIDE 5

Mental Activity vs Perception

  • Symposium paper(1951), Karl Lashley
  • Behaviorist – stimulus-chaining
  • Cognitivist movement
  • The role of perception in organizing

behavior

slide-6
SLIDE 6

Plans vs Behavior

  • Plans and the Structure of Behavior

(1960) - Miller, Galanter, and Pribram

  • Prescripted plan vs

Plan that unfolds incrementally trough time

  • TOTE unit

“Reactive planning”

SLIDE 7

The Mind vs The Body

  • STRIPS model (1972) – Fikes, Hart,

and Nilsson

  • Mind - constructs plans
  • Body - executes plans
  • Unintended situation
  • Rapid alternation

SLIDE 8

Abstract Ideals vs Concrete Things

  • Tradition of Fregean semantics
  • Psychologism – the theory that

meaning are mental entities

  • Platonism – the theory that meanings

reside in timeless, extensionless realam of ideals

  • Mathematical entities

Conclusion

  • Part of the history of Western

thought

  • World – negative, chaotic principle
  • Mind – positive, ordering principle
  • It Doesn’t Work That Way
  • Recognize the order inherent in the

world

  • Listen to and learn from reality
