6. The extent to which a person's attitude can be changed depends in part on how big a change you are trying to produce.In a classic study on persuasion, Aronson, Turner, and Carlsmith (1963) obtained three groups of subjects.One group listened to a persuasive message that differed only slightly from the subjects' original attitudes.For the second group, there was a moderate discrepancy between the message and the original attitudes.For the third group, there was a large discrepancy between the message and the original attitudes.For each subject, the amount of attitude change was measured.Hypothetical data, similar to the experimental results, are as follows:

Size of Discrepancy

Small Moderate Large

1 3 0

0 4 2

0 6 0

2 3 4

3 5 0

0 3 0
