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…

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…

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…

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…

A brief functional analysis indicated that the object mouthing of a young girl diagnosed with autism was maintained independent of social consequences. Separate and combined effects of response blocking and non-contingent reinforcement were then evaluated as treatments. Although both interventions were unsuccessful when implemented separately,…

This study evaluates parental use of differential reinforcement of other and/or incompatible behavior to treat high-rate disruptive behavior in a severely retarded four-year-old boy. A withdrawal experimental design was used. Intervention effectively reduced instances of toy chewing and throwing, while appropriate toy play and ability to remain…

Three severely mentally retarded adolescents who exhibited repetitive hand movements were assessed during baseline (reinforcement for on-task behavior) and sensory change (rings on fingers of both hands, rings and reinforcement, and faded rings) conditions. Sensory change effectively reduced the target responses for up to four hours. (Author/JDD)

This article reviews applications of the applied behavior analysis ideas of B. F. Skinner and others to persons with both mental retardation and emotional disturbance. The review examines implications of behavior analysis for operant conditioning and radical behaviorism, schedules of reinforcement, and emotion and mental illness. (DB)

This study used a data-based assessment to identify reinforcers and punishers for successful treatment of two children with severe destructive behaviors. Results suggested that empirically derived consequences may be useful in decreasing destructive behavior when a functional assessment is inconclusive or suggests that internal stimuli are…

This study involving five individuals (ages 5 to 21) with mental retardation and behavior problems, found that momentary changes in establishing operations can influence responding during the course of a functional analysis, and that comparisons of response levels associated with the presence or absence of putative reinforces can provide…

A study developed a systematic functional assessment package to reduce the stereotypy and self-injurious behaviors maintained by nonsocial reinforcement in two individuals with mental retardation. Differential reinforcement of zero rates of responding (DRO) procedures using stimuli within the targeted sensory classes were successful in eliminated…

Three analyses were conducted to assess the effects of different consequent stimuli on the stereotypical and self-injurious behavior of two children with severe developmental disabilities and dual sensory impairments. Contingent presentation of the specially selected stimuli plus response interruption resulted in more suppression than contingent…
