The study evaluated a reinforcement theory of stereotyped behavior with six autistic students (ages 9-16). Three students evidenced decreases in stereotypy and increases in responding in the presence of usual reinforcers, while the other three students required external suppression of stereotypy before increases in responding were shown.…

Two experiments examined the reinforcing value of response contingent sensory events consisting of combinations of visual, auditory, and vibratory stimulation with 10 nonambulatory profoundly mentally retarded individuals. Results indicated that systematically varying a multimodal sensory event is an effective way to identify positive reinforcers…

Treatment with two setting condition manipulations and use of a visual occlusion helmet was found to decelerate intense screaming by a 16-year-old girl with developmental disabilities. Cranial pressure was found to be the critical element in self-control, and replacing the helmet with a headband was found to be effective in maintaining behavior…

Four autistic and severely handicapped children (ages 9-13) were taught to recruit or set the occasion for praise from an adult. After the structured instruction, the children used these behaviors in all generalization settings and were frequently successful in recruiting praise. (Author/DB)

The effects of two levels of exercise (walking versus jogging) in suppressing the self-stimulatory behavior during academic programming of a 5-year-old boy with autism were examined. Decreased physical self-stimulation and "out of seat" behavior were found only for the jogging condition. Sharp reductions in these behaviors did not return…

The 10-year followup study of a severely retarded man treated for self-injurious behavior with a multiphased behavioral and vocational program found the incidence of self injurious behavior remained infrequent and rarely resulted in tissue damage. (Author/DB)

A study compared the effectiveness of two extinction interventions, extinction by omission and noncontingent delivery of reinforcement, to treat aggressive behavior with a 10-year-old boy. Analysis revealed that aggression was maintained by positive reinforcement in the form of attention. Noncontingent reinforcement of attention produced a more…

Comparison of eight individuals with mental retardation and severe, life-threatening, self-injurious behavior who received electrical aversive treatment with eight similar individuals who did not receive this treatment found that, over a 3-year period, electrical aversion treatment significantly reduced the degree of imposed mechanical restraints.…

This study evaluated use of the interpolation of reinforcement effect, which combines intermittent (INT) and continuous reinforcement (CRF) schedules, with four young children with autism using a free-operant preparation. Results suggest that responding may be less resistant to extinction following interpolated CRF reinforcement than following INT…

The literature on the use of physical restraint with adults and children with mental retardation is reviewed, including person-to-person restraint, mechanical devices, and voluntary self-restraint. Conclusions regarding outcomes of contingent and noncontingent restraint, maintenance, reinforcing effects of restraint, and risk of injury are…

This paper reviews the functional properties and procedural variations of differential reinforcement for the reduction of behavior disorders in individuals with developmental disabilities. The paper proposes that limited success may be a result of the arbitrary relationship that exists between reinforcers and target behaviors when behavioral…

A study of an adolescent with severe mental retardation, who demonstrated self-injurious behavior (SIB) when given attention, evaluated the extent to which providing attention only to appropriate communication would reduce SIB. The client's SIB was reduced significantly only when the therapist left the room when he engaged in SIB. (CR)

A study of a 15-year-old girl with autism who engaged in self-injury and aggression, found that gradually increasing the delay to reinforcement (access or escape), mand training, and extinction were effective for decreasing self-injury. Only when the gradual delay procedure was eliminated, however, was there a reduction in aggression. (Author/CR)

This review discusses the history of noncontingent reinforcement (NCR) and summaries findings from treatment research. It describes the use of NCR as a control procedure, NCR as a function-based treatment, considerations in the programming of NCR schedules, behavior-change mechanisms underlying NCR effects, and directions for future research.…

Level of spontaneous social initiating by three adult caregivers toward a youth with autism was studied during a program to increase the youth's level of social initiating. The youth's social initiations toward each adult were systematically reinforced. Frequency of spontaneous initiating toward the youth increased for each adult as the youth's…
