ABSTRACT
Petey runs, darts, and jumps with a ball clenched tightly in his arms. He screams “ok” to an invitation to play, but is unable to restrain his desire to keep the ball and game as his own. He pulls the ball away from another boy, angrily shoving him and screaming insults. In free play, individual, small group, or whole-group activities, he is angry, often out of control, hitting and throwing objects.
