Cognitive Psych Review

THE BASICS

1. The role of computation in cognition

2. Marr's levels (barn owl experiment)

1. Computational theory: What is the goal of the computation, why is it appropriate, and what is the logic of the strategy by which it can be carried out?

2. Representation and algorithm: How can this computational theory be implemented? In particular, what is the representation for the input and output, and what is the algorithm for the transformation?

3. Hardware implementation: How can the representation and algorithm be realized physically?

3. The brain as a multidimensional space

4. Awareness and consciousness (Chapter 2)

PERCEPTION

5. Generalization (Shepard’s Law states that the further away in psych. Space, the less of a chance of generalization).

6. Categorization

categorization: recognize objects as belonging to the same category, without losing information about their differences.

categorical perception as distortion of the representation space

7. Statistical nature of cognition (Mathematical averages of beauty)

8. Adaptation (page 77)

adaptation compensates for the statistical regularities of the world;

MEMORY

9. Cognitive maps
