1. What do the different visual agnosias tell us about perception? (Hard: What are the limitations, both theoretical and empirical, of using case studies of braindamaged individuals to inform theories of “normal” cognitive functions?)
2. Discuss the following: “Part of the reason that J. J. Gibson’s supporters and detractors have such spirited debates is that they are talking past each other. Gibson doesn’t just present a different model of perception—he redefines what the task of perception is.”
3. Consider McClelland and Rumelhart’s connectionist model of letter perception. How might a Gestalt psychologist regard this model, and what would he or she see as the model’s strengths and weaknesses? How might a cognitive neuropsychologist regard this model, and what would he or she see as its strengths and weaknesses?
4. a) In what ways are featural analysis and prototype-matching models an improvement over template-matching models? In what ways are they not? b) Evaluate the fit between Gestalt theories of perceptual organization and Biederman’s geon theory.
5. Perception sometimes involves “seeing” things that are not there (as in the case of subjective contours) or distorting things that are (as in the case of other context effects). Perception involves both bottom-up processes, which combine small bits of information obtained from the environment into larger pieces, and top-down processes, which are guided by the perceiver’s expectations and theories about what the stimulus is.
6. A) Predict which brain areas are likely to be most involved with the cognitive processes of perception, attention, memory, language, and problem solving. Provide a rationale for your predictions. B) Describe the functions of the four lobes of the cerebral cortex.

7) a) What is a mental representation, and how is this concept viewed by Gestalt psychologists, information-processing psychologists, behaviorist psychologists, and connectionists? b) Describe how research on cognitive development and individual differences might bear on cognitive psychology.

8) a) What roles do laboratory experiments and naturalistic observation play in cognitive research? b) What similarities and differences exist among the following three “schools” of psychology: structuralism, functionalism, behaviorism?
