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 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)

A brief negative-reinforcement assessment was conducted with five children (ages 4 to 14) with developmental disabilities with severe destructive behavior. Children were trained to engage in an escape response and were presented with a variety of stimuli. For each child, several stimuli were identified that may serve as effective negative…

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.…

This paper reviews the literature on functional assessment in the behavioral treatment of aggression in persons with mental retardation or developmental delays. Increased use of functional assessment and skill training is noted but no concomitant decrease in the use of intrusive procedures. (Author/DB)

A mindfulness-based, self-control strategy was developed for an adult with mental retardation and mental illness whose aggression had precluded successful community placement. He was taught a simple meditation technique that required him to shift his attention and awareness from the anger-producing situation to the soles of his feet. (Contains…

The study compared the effectiveness of (1) reinforcement of other behavior, (2) verbal reprimands, and (3) movement suppression time-out in eliminating self injury and aggressive behaviors in two severely mentally retarded adult males. Improvements were only apparent when movement suppression was paired with either or both of the other…

An adolescent with developmental disabilities who used a wheelchair was anecdotally observed to display little aggressive behavior when being pushed, but higher rates when movement was terminated. A functional analysis confirmed the elevated aggression and the child was taught to request movement through appropriate means. Aggression decreased…

A study analyzed reading level and readability of 20 behavior treatment plans developed by certified behavior analysts. Those with higher readability levels had somewhat better treatment outcomes. A second study involving four individuals found that manipulations of reading grade level and readability of behavior treatment plans greatly enhanced…

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,…
