Developing and maintaining social interaction in profoundly retarded young males.

Social interaction was increased in five profoundly retarded males using formal training, stimulus control, and rewarded generalization procedures. Seven behaviors were monitored for each boy to determine whether correlated changes occurred in maladaptive behaviors as social interaction varied over the several phases of a withdrawal design that included multiple-baseline features. All five boys increased their social interaction and reduced unoccupied and self-stimulatory behavior. These changes were maintained as continuous reinforcement was reduced to a single response-contingent reinforcer per 15-minute session. Four follow-up probes showed the stability of the changes.
