The study evaluated a reinforcement theory of stereotyped behavior with six autistic students (ages 9-16). Three students evidenced decreases in stereotypy and increases in responding in the presence of usual reinforcers, while the other three students required external suppression of stereotypy before increases in responding were shown.…

Two experiments examined the reinforcing value of response contingent sensory events consisting of combinations of visual, auditory, and vibratory stimulation with 10 nonambulatory profoundly mentally retarded individuals. Results indicated that systematically varying a multimodal sensory event is an effective way to identify positive reinforcers…

Three severely mentally retarded adolescents who exhibited repetitive hand movements were assessed during baseline (reinforcement for on-task behavior) and sensory change (rings on fingers of both hands, rings and reinforcement, and faded rings) conditions. Sensory change effectively reduced the target responses for up to four hours. (Author/JDD)

Studies assessing treatments for severe behavior problems of developmentally delayed persons were reviewed. Procedures used in the 382 studies, published from 1967-1987, were analyzed in terms of problem behaviors, side effects, and treatment methods. Also examined were number of studies reported yearly, maintenance and generalization of effects,…

The study compared the effectiveness of (1) reinforcement of other behavior, (2) verbal reprimands, and (3) movement suppression time-out in eliminating self injury and aggressive behaviors in two severely mentally retarded adult males. Improvements were only apparent when movement suppression was paired with either or both of the other…

Two experiments in training residents with severe disabilities in key use revealed increased ability to locate keys when reinforced for doing so and successful key use by 20 of 25 participants to open and lock their personal lockers. However, only 36 percent of participants were able to use their keys without prompts. (Author/DB)

Four mentally retarded children (ages 4-11), 3 with autism, were successfully taught various adaptive behaviors for self-care skills. Training procedures involved the whole-task method and included modeling, verbal instructions, prompting, and edible and social reinforcement. (Author/JDD)
