This thesis, whose subjects are only limited to elementary school students, investigates the patterns of children's perception of parental verbal aggression, children's aggression, and peer relationships, and examines the relative influence The subjects are 490 5th to 6th graders from 4 elementary schools in Gwangju and Chonnam Province. SPSS 12.0 is used to statistically analyze the data. The research findings are as follows ; 1. It is seen that among children's perception of parental verbal aggression, children's aggression, and peer relationships, there exists a meaningful negative correlation with respect to positive factors, and a meaningful positive correlation with respect to negative factors. 2. It is observed that as the father's verbal aggression is more severe, the more negative effect is imposed on the child's positive factors, emotional and social support, conflict resolution, and satisfaction with his/her peer relationships whereas the more positive effect is exerted upon the child's negative factors, 3. It is seen that the higher the children's aggression, the more negative effect is imposed on the child's conflict resolution and his/her satisfaction with peer relationships and the more positive effect is exerted upon conflict and opposition, one-sided leading, retraction, isolation, and his/her dissatisfaction with peer relationships. All things considered, it can be concluded that verbal aggression that parents frequently use as a method of control to remedy children's problem behaviors rather leads children not to be able to adjust themselves to their school life and thus leaves them with a lifelong psychological trauma. In particular, the relative influence of the father's verbal aggression is exerted upon the child's peer relationships to a greater extent. This thesis is of significance in that it is full of suggestions about how to discipline children and provides numerous empirical data by exploring the influence of parental verbal aggression and children's aggression on peer relationships.
