Focusing on the idea that victims of bullying may have cognitive/behavioral factors that could trigger exclusion from others,this study has conducted two experiments regarding peer representations. In Study 1, 93 boys and girls in Grade 5 performedMissing Interpersonal Relations – Pair Task and Perception of Interpersonal Relationship Questionnaire, and the resultsdemonstrated that children with negative peer representations viewed their own interpersonal relationships more negatively. InStudy 2, a separate group of 118 boys and girls in Grade 5 performed Interpersonal Relations (none missing) – Pair Task andPerception of Interpersonal Relationship Questionnaire, and the results demonstrated that children with negative peerrepresentations view interpersonal relationships between others more positively. The findings suggest that effectiveinterventions are crucial for victimized children. With the possibility of children victim’s perception bias actually bringingabout the victimization, counseling intervention to modify such perception bias seems necessary.
