This study was designed to examine the effect of gross motor activity on the social skill acquisition in the children diagnosed as autism, the pervasive developmental disabilities, and the Asperger syndrome. It is especially difficult for children in this study to observe the rules, and to feel surrounding circumstances, and play with others jointly. In gross motor activity, a lot of interpersonal behaviors could be seen, and they came to recognize the rules and cooperate with others. Moreover, to the parent, it was a good chance for recognizing their child's behavior problem objectively. From these results, the gross motor activity is effective for the development of social skills.
