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 6 times they had behaved assertively and asked other participants to think of 12 times they had behaved assertively,and then asked all participants to rate how assertive they thought they really were.Participants who tried to generate 6 examples of assertive behaviours rated themselves as more assertive than did participants who tried to generate 12 examples.Why?

A) Participants asked to think of 12 examples didn't have time to complete the experimental task.
B) Participants who could generate 12 examples were really more assertive,or else they couldn't come up with the examples.
C) Participants who were asked to generate 6 examples were more likely to use the representativeness heuristic.
D) Participants asked to generate 6 examples could do so more easily than participants who were asked to generate 12.
E) Participants asked to generate 12 examples could do so just as easily than participants who were asked to generate 6.
