Abstract:  Matched 20 aggressive and 20 nonaggressive 8-38 yr. Old institutionalized mentally retarded ss on age, sex, and iq. Ss were shown either an “aggressive” or a “friendly” television film of a child playing with a large inflatable doll. Results indicate that friendly ss modeled the aggressive film behavior in the experimental room, while aggressive ss did not. Friendly behavior increased and aggressive behavior decreased after the friendly film. Later, in the ward, ss who had seen the aggressive film were more aggressive, and ss who had seen the friendly film were more friendly. However, results apply mainly to friendly ss’ behavior, since they were more friendly even after the aggressive film than aggressive ss were after the friendly film. Specific modeling was incomplete, the behavior in the ward being more related to the general mood of the film than to the specific actions seen in the film.
