Abstract
In this study, the Rosenzweig P-F Study, selected TAT pictures, and a Sentence Completion Test were administered at intervals throughout the season to the following college groups: 9 boxers, 8 wrestlers, 9 cross country runners, and 17 control subjects. The tests were analyzed for number, severity, and direction of aggressive responses. Significant differences indicated that the boxers were least aggressive of the groups, and that they tended to direct their aggressive feelings inwardly (intra-punitive) rather than outwardly upon persons or things in their environment (extra-punitive). Indications were that the intensity and direction of aggression of these various athlete and non-athlete groups were quite different. The Thematic Apperception Test was judged the best instrument for assessing aggression.
