Findings from a randomized controlled design study of an ability-based versus needs-based approach to response-contingent learning among children with significant developmental delays and disabilities who did not use instrumental behavior to produce reinforcing consequences are reported. The ability-based intervention and needs-based intervention…

This study evaluated use of the interpolation of reinforcement effect, which combines intermittent (INT) and continuous reinforcement (CRF) schedules, with four young children with autism using a free-operant preparation. Results suggest that responding may be less resistant to extinction following interpolated CRF reinforcement than following INT…

A combination of reinforcement for correct imitations and timeout for failure was more effective in establishing imitation in a 4-year-old institutionalized retarded child than reinforcement used alone. (CL)

A parent-conducted program of verbal response-contingent stimulation was effectively used to reduce stuttering to near zero levels in 12 children (younger than age 5). Treatments were completed in a median of 10.5 1-hour clinic sessions and 84.5 days. (Author/DB)

Five profoundly retarded males (6 to 9 years old) with clinical manifestations of autism were used to evaluate the use of operant conditioning techniques to toilet train children in an autism ward of a hospital for developmentally disturbed children. (Author/SBH)

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…

This review summarizes and discusses literature relevant to the communication development of young children (0-5 years) with deaf-blindness. The review is divided into topical areas. The topical areas and the contributors for each area are as follows: "Perspectives on Communication Assessment" (Charity Rowland); "Research in Tactile…
