Five adult males with profound retardation were assessed on a motor task during baseline, satiation, and deprivation conditions, with three classes of consequences: small food items, music, and social praise. Each stimulus class functioned as reinforcement, with different degrees of effectiveness during satiation versus deprivation conditions.…

The effects of a variable-ratio schedule of reinforcement on pedaling a stationary exercise bicycle were examined with 3 obese and 3 nonobese 11-year-old boys over a 12-week period. The intervention resulted in systematic increases in rate of exercise for all subjects. (Author/DB)

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)

A broad spectrum behavior therapy approach was used to treat physical aggression in 5 brain-injured males (ages 18-28). The approach employed high density reinforcement, reinforcer sampling, environmental control, selection of appropriate responses, inconvenience review, self-control training, and self-monitoring. All five subjects showed…

Generalization across three stimulus parameters (therapist, setting, and demands) was examined for five men with severe/profound mental retardation whose self-injurious behavior was maintained by escape from task demands. Variables were held constant during the escape extinction treatment. Full or partial generalization to novel situations was…

Behavioral techniques (positive reinforcement and nonexclusionary timeout) effectively decreased problem behaviors of noncompliance and aggression of a young adult male with severe mental retardation and Down's syndrome residing in the community. (DB)
