An extensive…

Using prompting and reinforcement procedures, five severely retarded individuals were trained and employed as client care workers to provide verbal and physical interaction and leisure materials to nonambulatory, multiply=handicapped residents of a mental retardation facility. Levels of interaction equalled or exceeded those displayed by exemplary…

Prompting, positive and negative reinforcement, and a gradually extended reinforcement schedule were used with three autistic clients (two six-year-olds and one adolescent) to teach them to maintain on-task behaviors without constant supervision. Results indicated that appropriate behavior could be successfully maintained with only infrequent and…

The study sought to identify effective procedures for facilitating initial imitative vocal behavior in mentally retarded children, thus accelerating the initial stages of language acquisition. Three groups of Down syndrome children ages 6 months to 4 years (N=15) served as subjects in an examination of the relative effectiveness of three…
