At present, the problem of youth violence in China are increasingly serious, the number of young gang crimes is growing each year, acts of bullying were often seen in campus, these phenomena have attracted the close attention of the whole society.Since the last century, the scholars at home and abroad launched a wide range of research on attack, but experiment research comparing aggressive behavior committed by groups and individuals is sparse. Thus, the experimental study in this regard is very necessary. We use hot sauce experiment, Aggression Questionnaire and developed perceived personal responsibility scale to study 118 junior high school boys' aggression. The experiment compared aggression behavior in four different types of situations: intergroup, interindividual, group-to-interindividual, and interindividual-to-group. The result showed that:1. A group is either the source or target are situational influences that can increase it.2. In groups, perceived personal responsibility of individual is lower the conditions of individual, but it can not reconcile hot sauce distribution between groups and individuals conditions.3. In individual conditions, there is no significant relationship between physical aggression of subjects and distribution of hot sauce, and there is significant relationship between hostility and distribution of hot sauce. In group conditions, there is no significant relationship between the four dimensions of aggression of subjects and distribution of hot sauce.4. There is significant difference on aggression between intergroup and interindividual, The aggression of intergroup is higher than interindividual.5. overall, the aggression of interaction of individual and group is higher than the interaction between individual. |
