Anger and the use of defense mechanisms in college students.

It was hypothesized that experimentally induced anger would result in an increased use of defense mechanisms in college students. As predicted from the theory of defense mechanism development, the Thematic Apperception Test (TAT) stories of angered students showed a higher level of use of projection and identification, and the use of these defenses was significantly correlated with the presence of aggressive content in the stories. The results were consistent with previous studies in showing that the predominant defenses of late adolescents are projection and identification, and that men use more projection than women.
