What is a dissociation? What information does it tell us about cognitive processing? How does a double dissociation improve upon this information?
 
  What will be an ideal response?

Question 2

Explain why artificial intelligence researchers are interested in designing complex processing systems that perform human tasks. What are some of the strengths and weaknesses of this approach?
 
  What will be an ideal response?

Answer to Question 1

Answer: A dissociation means that an activity or a variable affects performance on one task. In double dissociation, an activity or variable affects one process (P1) but not another (P2) while a second activity or variable has the opposite affect (impairs P2 but not P1). Double dissociations provide strong evidence for two processes.

Answer to Question 2

Answer: AI researchers believe that human cognition is so complex that creating a processing system that performs similar tasks can provide insight into human cognition. While the AI approach can lead to important insights, AI research often ignores how processing takes place in the brain.
