Time-out is a negative punishment procedure that parents and teachers commonly use to reduce problem behavior; however, specific time-out parameters have not been evaluated adequately. One parameter that has received relatively little attention in the literature is the mode of administration (verbal or physical) of time-out. In this study, we…

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…

This paper reviews the functional properties and procedural variations of differential reinforcement for the reduction of behavior disorders in individuals with developmental disabilities. The paper proposes that limited success may be a result of the arbitrary relationship that exists between reinforcers and target behaviors when behavioral…

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…

The effects on compliance of two types of differential negative reinforcement (DNR) were studied with a five-year-old girl with moderate mental retardation and a history of severe disruption. Escape from instructional trials was either contingent on a communicative behavior or compliance. Behaviors improved with both interventions, but compliance…
