Noncontingent reinforcement (NCR) was applied to reduce the destructive behaviors of five-year-old quadruplets diagnosed with mental retardation and pervasive developmental disorder. Findings suggest that the effectiveness of NCR may be dependent on the use of a dense schedule of reinforcement initially and that systematic fading can increase the…

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 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…

This study compared selection of a preferred reinforcing stimulus just prior to a training session by either the trainer or subject with profound developmental disabilities. Results obtained with four adult subjects indicated little or no difference in reinforcement effects when reinforcing stimuli were selected by subjects rather than trainers.…

A simultaneous presentation procedure to select reinforcers was implemented with two four-year-old twin boys who were developmentally delayed, noncompliant, and mute. Use of the procedure quickly and efficiently identified preferred reinforcers which were then used in an instructional task. (DB)

Analysis of videotapes of training procedures with 12 developmentally disabled adults in a horticultural day work program found an overall staff emphasis on selectively attending to workers' successful behavior with evidence of both efficiency and effectiveness of this approach. (Author/DB)
