Introduction to Cognitive Science
Study Guide for the First Test
 
Dawson will be Chapters One through Three
Topics:
Chapter One:
Tri-level hypothesis
Cognition as information processing
Dissatisfaction with the classical model
Chapter Two:
Given the Turing machine is the paradigm case of a computing device, what is computation?
What are the attractions the Turing machine offers as a model of the mind?
Dawson argues for the tri-level hypothesis from 24 onwards; his arguments often invoke regularities. What sort of claim is he making?
Chapter Three:
First three potential problems for connectionism: 37-38.
The additional problems: 38-39.
Advantages of connectionist model over classical model
Connectionism and the tri-level hypothesis (summarized on p. 65).
