The purpose of this study is to settle the hypothesis on the stages of bullying in childhood. The three stages I identified are as follows. Stage 1 (from 6 to 9 years) Children of this stage view conflicts as a problem which is felt by one party and caused by the actions of the other. For this social-cognitive limitation, other children unilaterally assault or bully the party which is recognized to have been guilty. Stage 2 (from 9 to 11) Children of this stage often make the rule of their group, and the child who is recognized to have broken the rule is attackd or bullied by other members of the group. Stage 3 (from 11 to 14) Children of this stage often make an intimate group composed of the same sex children, but if someone dose't conform to the way of the group, he or she is excluded from other members. I suppose understanding these stages of bullies is prerequisite for the teacher to help the pupils who are involved in the bullying problem.
