Discussion: For each of the following topics, list the pros and cons of a between-
subjects and within-subjects design and decide which would be better.

1. You want to test the relative effectiveness of two training programs for
running a marathon.

2. Using photographs of people as stimuli, you want to see if smiling people are
perceived as more intelligent than people who are not smiling.

3. In a field experiment, you want to see if the way a panhandler is dressed
(neatly vs. sloppily) affects whether or not passersby give him any money.

4. You want to see if concrete nouns (e.g., dog) are recalled better than abstract
nouns (e.g., truth).
