Two studies were conducted to test how the effects of the following situational factors and general trust influenced aggressive behavior. Forty-two male undergraduates participated in the following 2 studies. In study 1, the effects of the number of aggressor (i.e. individuals vs. groups) and aggressor’s general trust on aggressive behavior were investigated in a laboratory setting. In study 2, the effects of categories about the victims (i.e. outsiders vs. acquaintances) and the aggressor’s general trust on aggressive behavior were investigated in the same method as study 1. The results showed that members with both high and low levels of general trust, when they were in groups, refrained more from exerting aggression toward the opponent, furthermore, members with low level of general trust exerted more aggression toward the opponent as outsiders than that of acquaintances. Thus, the hypothesis that members with low level of general trust, when they were in groups, might exert much more aggression toward outsiders compared to those with high level of general trust was confirmed partially.
