Psychology of Social Influence

A frequency distribution of verbal conditioning data was found to be quite bimodal. The upper mode was populated exclusively with Ss who claimed to have been aware of and cooperating with demand characteristics during the experiment. Contrary to expectations, S sophistication (time of semester) did not significantly increase verbal conditioning. Postexperimental estimates by aware and cooperating Ss as to the point at which they became aware correlated highly with the point at which they first showed a decided preference for reinforced pronouns.
