Abstract
(1) Effects on aggressive behavior of interpersonal relations between the frustrator and the frustrated were investigated. (2) Hypothesis I: Aggressive behavior will be exhibited greater when they belong to the different group (out-group-relation) rather than to the same group (in-group-relation). Hypothesis II: Aggressive behavior will be exhibited greater when the frustrator is higher in status than the frustrated rather than vice versa. (3) Ss, 100 undergraduate students, were given questionnaires on which they indicated the responses that “people” would make in various frustrating situation. As the questionnaires, the pictures of the modified P-F study were used. (4) Results provided strong support for the hypotheses.
