We investigated the relationship between university students’ attitudes and how they responded under stress when shown scenes of frustrating situations during a Picture-Frustration study (P-F study). As a result, it was suggested that the height of awareness of the stress response was related to the characteristics of aggression processing, such as how to portray Obstacle-Dominance in the P-F study and assign aggression in an irresponsible direction. It was speculated that in the attitudes of both expressing and suppressing frustration, if the frustration cannot be resolved, the inability to express it may become a new stressor and increase the stress response. In contrast, it was shown that an Intropersistive reaction in the P-F study was related to low awareness of the stress response. It was thought that taking actions to eliminate or reduce one’s frustration lead to a low awareness of the stress reaction. Additionally, our results also suggested that the kind of reaction and/or sensation perceived by the body during the interpersonal stress scene may be related to the characteristics of the aggression processing shown in the P-F study.
