A study tested whether four students with mental retardation would substitute task-related behaviors for stereotypic behaviors when opportunity for active responding did or did not match level of motoric responding in a free-operant baseline. Students did substitute behaviors, with stereotypic behaviors occurring 1.5-14 times as much in the…

This replication study found that only 16 of 55 raters agreed on the category of reinforcement maintaining a disabled individual's self-injurious behavior after using the Motivation Assessment Scale. Additionally, only 15 percent of the correlation coefficients obtained were above 80 percent, and none of the reliability scores was above 80…

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…

A study investigated the validity of the Questions about Behavioral Function, a checklist designed to assess antecedent behavior, using a sample of 398 persons with mental retardation and self-injurious behavior, aggression, or stereotypies. The checklist was used successfully to derive clear behavioral functions across all three target behaviors.…

A study examined the effects of progressive relaxation training on the disruptive behaviors of a 12-year-old boy with autism. The participant acquired progressive relaxation skills, displayed more relaxed behavior after performing the procedures, and showed a decrease in the duration of his disruptive behavior upon completing progressive…

Two cases are presented in which modifications to the social attention condition were needed to identify maintaining contingencies for two young children with mental retardation and destructive behavior. The effects of two different qualities of social attention are examined, along with the effects of contingent verbal, versus contingent physical,…

Twelve individuals (ages 3-43) with severe/profound mental retardation and life-threatening self-injurious behaviors were exposed to electrical aversion treatment using a remotely controlled device. With seven individuals, suppression of the behavior was nearly complete in that physical restraints were no longer necessary. With three individuals,…

Treatment of a woman with severe mental retardation with the Self-Injurious Behavior Inhibiting System (SIBIS) resulted in significant reductions in SIB behavior which generalized to the natural environment and the brief follow-up sessions. (Author/DB)

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)

The study evaluated the indirect effects on stereotypic behavior frequency of several fixed-interval reinforcement schedules on behaviors of three profoundly retarded adults. Stereotypic behavior increased in direct relation to the interval length suggesting such behaviors may be partially controlled by reinforcement frequency for adaptive…

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…

This study evaluated a multicomponent treatment package with three adults having profound mental retardation who engaged in self-injurious hand mouthing. The intervention, which involved brief response interruption followed by the introduction of a preferred leisure item, was successfully implemented during both individual and small group…

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…

A function-based behavioral treatment package was developed for an 18-year-old male with mild mental retardation in a specialized inpatient unit for treatment of severe destructive behaviors associated with school refusal behavior. Treatment goals were achieved relatively quickly and follow-up data indicated treatment effects were durable.…
