Problem 3.1 (1.5 pages) Following our discussion of neural networks in class (and using the readings as well), briefly summarize the following concepts:

a. Backpropagation
b. Distributed representations
c. Feedforward nets
d. Contrasts between neural networks and semantic networks

Problem 3.2 (2 pages) This question focuses on recent research in memory, as discussed in class and in the reading from Schacter. For each of the following research traditions, describe an example illustrating how that tradition has contributed to our understanding of human memory:

a. Clinical (medical) evidence
b. Laboratory experiments in cognitive psychology
c. Computational models
