【简答题】
The names of category prototypes tend to come to mind before those of peripheral examples. Check this hypothesis with two informal tests: Ask one group of friends to name as quickly as they can five types of dogs, birds, trees, and cars, and a second group to rate these examples according to their goodness-of-example status within the category. Compare the results and discuss reasons for discrepancies between the two tests.
