| Abstract: | The effects of toy guns and toy airplanes on children's antisocial (aggression and rule-breaking) behavior was investigated in two settings (ten children in Study I and 13 in Study II) during 30-min free play sessions. Four-and 5-year-old children were observed during 15–16 free play sessions. During some sessions the children played either with (novel, aggressive) toy guns or with (novel, nonaggressive) toy airplanes in addition to their usual toys. In both studies, the toy guns treatment produced a reliably higher rate of antisocial behavior than the average of the toy airplaines and the usual toys. The novel-nonaggressive toy airplanes also increased the rate of antisocial behavior as compared to usual toys in Study II. The results were related primarily to Berkowitz's and Bandura's analyses of aggressive behavior, but they were related also to other theoretical models which predict stimulus control of behavior. |
