Janis and King (1954) Investigated the Effect of Role Playing

Janis and King (1954) investigated the effect of role playing on attitude change. They found that participants:

A) who had their position reinforced by an expert were more likely to convince others of their position.
B) who gave a speech contrary to their position changed their attitude more than when they just listened to other speakers.
C) with low self-esteem, and who were female rather than male, showed more attitude change.
D) who listened to a speech by a friend were more likely to adopt a new position.
