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…

The self-injurious behaviors of nine subjects with developmental disabilities were observed in settings in which play materials, experimenter demands, or social attention were systematically varied. Although there was much between-subject and within-subject variability, higher levels of self-injury were consistently associated with a specific…

This study examined methods for determining how extinction should be applied to different functions of self-injurious behavior, specifically head-banging of three children with developmental disabilities. Since each subject's head-banging was maintained by different reinforcement contingencies, behavioral treatment techniques, although all based…

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…

This article reviews the development of functional analysis in understanding behavior problems like self-injury and aggression and, more recently, school-based problems. Seen as particularly promising is current work on the analysis of setting events and analysis of dependent variables by considering the effects of intervention on response…

This study compared rates of self-injurious behavior (SIB) exhibited by a 32-year-old woman with profound mental retardation across conditions in which access to restraint was either continuously available, presented as a consequence for SIB, or unavailable. Rates of SIB increased when access to restraint was contingent upon SIB, suggesting that…

Four studies analyzed eye poking behavior of a youth with profound disabilities. Results demonstrated substantive reductions in the frequency of eye poking when goggles were worn and when a video game was provided as a competing source of visual stimulation and as a reinforcer. Music was less effective in reducing eye poking. (Author/DB)

Covert self-injurious behavior in a 21-year old with mild mental retardation and cerebral palsy was treated by first identifying tangible and social reinforcers and then providing reinforcers contingent on absence of tissue damage identified during physical examination. Almost complete success was achieved and maintained over 10 months. (DB)

This study evaluated effects of noncontingent and contingent protective equipment as treatment for self-injurious hand mouthing by two women with profound mental retardation. Behavior change appeared to be effected in both conditions. Results suggest either a punishment or a timeout interpretation, rather than an extinction interpretation, for the…

Results of a functional analysis indicted that the hand mouthing of a woman with profound mental retardation was maintained by multiple sources of control (sensory stimulation and access to a leisure item). Hand mouthing, though maintained by automatic reinforcement, was also susceptible to social contingencies when exposed to them during…

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…
