Recall That Norbert Schwarz and His Colleagues (1991)asked Some Participants

Recall that Norbert Schwarz and his colleagues (1991) asked some participants to think of six times they had behaved assertively and asked other participants to think of twelve times they had behaved assertively,and then asked all participants to rate how assertive they thought they really were.Participants who tried to generate six examples of assertive behaviors rated themselves as more assertive than did participants who tried to generate twelve examples.Why? Schwarz suggests that participants

A) who could generate twelve examples were really more assertive,or else they couldn't come up with the examples.
B) asked to think of twelve examples didn't have time to complete the experimental task.
C) asked to generate six examples could do so more easily than participants who were asked to generate twelve.
D) who were asked to generate six examples were more likely to use the representativeness heuristic.
