Cognition-Chapter 1

Thinkers
1. Descartes
  1. Mental representations are ideas that take form
2. Hobbes
  1. Mental processes are calculations
3. Turing
  1. Invented the machine: finite states+ finite rules= infinite capacity
Knowledge
1. Implicit
  1. Innate
    1. Whatever enables you to perform cognitive tasks, mostly unlearned
2. Explicit
  1. The one that we acquire and are conscious of
    1. By experience
      1. Semantic
        Common of the world, concepts
      2. Episodic
        Own view, personal experience
Levels of analysis
1. Computational
  1. Mechanism of information processing
  2. Isolate components
  3. INPUT
2. Representations and algorithms
  1. Representing something external
  2. System manipulates representations
  3. SET OF RULES
3. Implementation
  1. Where and how processes are realized
  2. The brain
4. Marr
Science of human nature- study in lab
1. Brain
  1. Can study neurons but won't tell us how mental representations fit
  2. Organ of the mind
  3. Formal device that manipulates code
2. Mind
  1. Mental representations that we can't see
  2. Works like a turning machine
Behaviour
1. Dictated by our knowledge
  1. Set of rules encoded in the brain
The study of mental representations, and processes involved in the acquisition, storage, retrieval and use of knowledge
1. Mental representations
  1. Things in the mind that stand for things in the world
  2. Computations (MTP)
2. Processes
  1. Operations over representations
Disciplines
1. Behaviourists
  1. What's observable+ physical laws
2. Cognitivist
  1. What's observable+ physical laws + rules (non observable)
    1. We need to understand how the brain works but it's not enough
