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

sigmoidal curve

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

10. STM and LTM

11. Meta-memory

12. Schemata

LANGUAGE

13. Speech

14. Sentence processing (p. 301-303)

15. Semantic holism

Instead, they have meanings only when they hang out with other sentences.

Statements about the external world face the tribunal of experience not individually but only as a corporate body."

16. Acquisition

the transitional probability from one sound to next will be highest when the two sounds follow one another within a word, whereas transitional probabilities spanning a word boundary will be relatively low.

THINKING

17. The frame problem

This presented the "frame problem": how to design a system that could, unlike poor C3,
