Problem Set 5, Due: Monday, Nov. 11, 2002

Problem 1. (2 pages)

Modifiers (words that add information to the noun or verb they describe) can give us clues about the way categories are structured.

In approximately two pages, explain how the following modifiers work: fake, imitation, artificial, real, true, genuine, authentic. Apply them to a few of the categories listed here, or to other relevant examples you can think of: pants, teeth, fur, leather, flowers, democracy, Picasso, gun light, lamp, maple syrup, emotion, flavor, modesty, book.

Discuss how the meanings of the modifiers combine with your knowledge about the nouns to explain why the modifier-noun pairs behave as they do. In particular, how do the modifiers change the categories they describe? Can you generalize a meaning for the modifier? What does this suggest about the structure of these categories? Do frames play a role in these definitions?

You don't have to do every combination, and you should make up examples not given here. Try not to discuss more than about a dozen combinations, so pick your examples to be maximally revealing.

You should be able to answer such questions as:

We recommend you form small groups to discuss this problem. If you do work in a group, remember that the write-ups must be done individually. List the names of all your group members at the top of your paper.

Problem 2. (2 pages)

Based on the reading from Tye and the material presented in class, discuss several experimental phenomena from the literature on mental imagery. Try to present alternative interpretations (i.e., "visual-imagery-oriented' vs. "symbol-oriented" -- or, if you prefer, "non-visual-imagery-oriented") of at least two of these.
