USE OF POSITIVE REINFORCEMENT IN CONTROL OF SELF-DESTRUCTIVE BEHAVIOR IN A RETARDED BOY

Severe self-destructive behaviors in an 8-year-old boy were observed to change as a function of treatment procedures which included both primary and secondary reinforcers and a brief walk across the room. The presentation and withdrawal of a blanket also appeared to exert considerable control over the frequency of self-destructive behaviors. The results were discussed in terms of environmental control through self-injurious behaviors and the development of the blanket as a reinforcing stimulus. © 1968.
