After finding that self-injurious behavior in two young males with developmental disabilities was negatively reinforced by escape from instructional activities, an intervention provided noncontingent escape on a fixed schedule and differential negative reinforcement of other behavior. Provision of escape, even when noncontingent, resulted in…

A contingency management procedure using both positive and negative reinforcement was used to strengthen cooperative behavior in five children (ages 3-6) during a series of restorative dental treatment sessions lasting from 15-60 minutes. Baseline levels of disruptive behavior as high as 90 percent were reduced to less than 15 percent. (JW)

Three studies investigated environmental correlates of self-injurious behavior in seven developmentally disabled children and adolescents which were then later used for treatment. Correlates investigated included positive reinforcement, negative reinforcement, automatic reinforcement, and control. "Escape extinction" was successfully…

This study of the treatment of self-injurious behavior (SIB), involving three individuals with developmental disabilities, found that an extinction condition in which SIB no longer produced escape reduced SIB to the criterion in fewer sessions than did extinction plus fading, in which instruction frequency was initially reduced to zero and then…

Obscene verbalizations in an individual with traumatic brain injury were treated using stimulus fading as the singular form of intervention. Results of a functional assessment revealed the obscenity was maintained by negative reinforcement. Stimulus fading (the gradual reintroduction of instructional demands) produced immediate and substantial…

Functional analysis of the self-injurious behavior (SIB) of three individuals with profound mental retardation indicated the behavior was maintained by negative reinforcement (escape from instructional situations). Stimulus fading was applied. Results indicated that instructional fading virtually eliminated SIB, but these effects were not…

Analysis of the effects of a short break contingent on completed work with a 10-year-old boy with autism and profound mental retardation found the 20-second break increased responding more than a positive reinforcer did, and the reinforcing effects of a 20-second break were affected by the availability of positive reinforcers during the break.

Prompting, positive and negative reinforcement, and a gradually extended reinforcement schedule were used with three autistic clients (two six-year-olds and one adolescent) to teach them to maintain on-task behaviors without constant supervision. Results indicated that appropriate behavior could be successfully maintained with only infrequent and…

A study of the relationship between presence or absence of sleep deprivation, allergy symptoms, and the rate and function of problem behavior in three adolescents with moderate to profound mental retardation found that problem behavior was negatively reinforced by escape from instruction, and both allergy symptoms and sleep deprivation influenced…

Functional analyses of problem behaviors were performed with three individuals with severe intellectual disabilities. Results indicated that the problem behaviors were maintained either when the behavior resulted in escape from difficult tasks or when the behavior resulted in access to preferred items. Training in functionally equivalent…

Two severely handicapped children (ages 5-6) exhibiting self-injurious behavior were treated with negative reinforcement (brief escape from grooming activities) contingent upon a behavior that was incompatible with self-injury (pressing a microswitch that activated a "stop" message). Treatment led to decreased self-injury, which was maintained at…
