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…

Several studies identifying establishing operations for negatively reinforced behavior among nine adults with developmental disabilities are reported. After verifying through functional analysis that self-injurious behavior was maintained by escape, some establishing properties of task demands were investigated by systematically altering task…

A study of an adolescent with severe mental retardation, who demonstrated self-injurious behavior (SIB) when given attention, evaluated the extent to which providing attention only to appropriate communication would reduce SIB. The client's SIB was reduced significantly only when the therapist left the room when he engaged in SIB. (CR)

This study compared the effectiveness of differential negative reinforcement of other behavior (DNRO) and alternative behavior (DNRA) for reducing self-injurious tantrums maintained by escape from demands in a 4-year-old girl with severe retardation. Both DNRO and DNRA reduced self-injury and increased independent task performance, with DNRA…

A functional analysis was conducted which showed that self-injurious behavior (SIB) of an adult with mental retardation occurred at differentially high rates when restraint materials access was contingent on behavior. An alone condition during the functional analysis showed SIB did not occur in the absence of restraint materials. Functional…

A study compared effects of continuous reinforcement (play) and alone conditions as controls during functional analyses for 66 individuals whose self-injurious behavior (SIB) was maintained by escape. SIB was lower during both control conditions than it was during the test (demand) condition. SIB was lowest during the alone condition. (Author/CR)

This study examined the effects of blocking self-injurious behavior on the self-restraint of a 19-year-old male with severe mental retardation. Consistent with the negative reinforcement hypothesis, blocking SIB resulted in near-zero levels of SIB and moderate reductions in self-restraint. (Author/DB)

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…

Effects of extinction and negative reinforcement on latency of responses (including aggression and self-injurious behavior) following activity requests to an adolescent girl with mental retardation and autism were evaluated. Results showed that latencies occurred in a predictable order. The response class was expanded to include an appropriate…

The self-injurious escape behavior of an adult with developmental disabilities was treated with extinction. Results of a reversal design showed substantial bursts of responding when extinction was introduced and reintroduced: self-injury remained at a variable and elevated rate for some time before stable, low rates were observed. (Author/DB)

Results of a functional analysis of self-injurious behavior (SIB) in a 7-year-old child with autism showed that her SIB was maintained by access to preferred object and escape or avoidance of task demands. Warning stimuli in combination with extinction and noncontingent reinforcement reduced SIB to acceptable levels. (Author/CR)

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…
