Two autistic boys, ages 6 and 10 years, whose imitative responding was functionally inaccurate and whose performance generalized poorly, were trained to imitate accurately using a reinforcement-extinction strategy. (DLS)

The use of operant procedures was extended to decrease immediate echolalia and increase appropriate responding to questions of a 21-year-old autistic man. Multiple baseline designs demonstrated that echolalia was rapidly replaced with correct stimulus-specific responses. A variety of generalized improvements were observed in verbal responses to…

The mothers and fathers of 11 preschool autistic children were taught operant procedures used in teaching speech to nonverbal children. At posttreatment, the children showed significant gains in pre-speech and speech skills as measured by a 21-step hierarchy of speech behaviors. (Author)

This critical review examines 10 controlled studies in which traditional operant behavioral procedures were compared with normalized interventions for teaching language to young children with autism. It concluded that normalized language training was substantially more effective than discrete-trial training and yielded more positive parental…

In a study of behavior modification two Down's syndrome preschool children, the first a 5-year-old boy with autistic behavior patterns and the second a 4-year-old girl whose behavior problem was to reject other children, were examined. The first S was engaged in ball catching activities with a teacher with positive reinforcement (playing the S's…

The proceedings of the Second Annual Meeting and Conference of the National Society for Autistic Children begin with three brief statements regarding the Joint Commission on Mental Health of Children. Following are the keynote address by Edwin W. Martin concerning the rhetoric and reality of the Federal response to the educational needs of…

We tested the effect of multiple exemplar instruction (MEI) on acquisition of joint spelling responses, vocal to written and vice versa, for three sets of five words by four kindergarteners with language delays using a delayed multiple probe design. First, students were taught to spell Set 1 as either vocal or written responses (two vocal and two…

This paper attempts to provide a brief overview of the diagnosis, etiology, and treatment strategies presently being used with atuistics. Discussion of treatment strategies revolves around the use of operant techniques; from Lindsley and Skinner (1954) to more recent attempts of Lovaas (1976). Generalization and maintenance are also discussed in…

Reported was a behavior therapy program emphasizing language training for 20 autistic children who variously exhibited apparent sensory deficit, severe affect isolation, self stimulatory behavior, mutism, echolalic speech, absence of receptive speech and social and self help behaviors, and self destructive tendencies. The treatment emphasized…

The stereotyped, self-stimulating, autistic behavior (such as head weaving or body rocking) of 32 severely or profoundly retarded adults in a state hospital ward was virtually eliminated through nonreinforcement, reinforcement accompanied by praise, reinforcement combined with autism reversal procedures, and only autism reversal procedures. (MC)

Five children with autism and mental retardation learned to discriminate objects in response to spoken names or to match amounts to numbers with a combined blocking procedure. The procedure involved presenting the same spoken word until 10 consecutive correct responses occurred and keeping the left-right location of objects constant. (Contains…
