The purpose of this study was to determine the effect of manual sign mand training combined with prompt delay and vocal prompting on the production of vocal responses in nonvocal children with developmental disabilities. A multiple baseline design across participants verified the effectiveness of this intervention. All participants showed…

Listed with ordering information and in some cases brief annotations are 61 resources pertinent to use of manual communication by retarded, autistic, and aphasic individuals who cannot communicate effectively by speaking. (JG)

The results indicated that overcorrection plus positive reinforcement was effective in teaching one sign (milk); however, an added contingent exercise (having to stand up and sit down 10 times for an incorrect response) was required to teach the second sign (cookie). (Author/SW)

Suggestions of writers such as A. Holland and M. Lahey and L. Bloom are examined regarding their appropriateness for visual-manual communication and are applied to approximately 50 signs most frequently taught to retarded and autistic persons to aid in lexicon planning. Additional signs are proposed for extending this basic list. (Author/DLS)

Three questions regarding the use of sign language as an alternative communication system for nonverbal autistic children are examined. Data on effects on speech, the upper limits of sign acquisition, and effects on adaptive function are discussed. (Author/CL)

Mothers of four 6- and 7-year-old autistic classmates were taught to use manual signs with verbalizations to aid development of appropriate communicative behavior and to deter undesirable behavior in their children. (Author)

A discussion of techniques developed to foster spontaneous verbal language in autistic children. Signed speech refers to the simultaneous production of signs and speech. After several months of this, the signs are faded out and the verbal language remaining is employed in a creative fashion. (AMH)

Four nonverbal autistic children (10-15 years old) were taught expressive sign labels for common objects, using a training procedure that consisted of prompting, fading, and stimulus rotation. (Author/BD)

The use of sign language with severely handicapped students is analyzed in light of commonly held rationales. Cognitive, motor, and sociocommunicative factors affecting the learning of sign language are discussed, as well as environmental considerations (including attitudes toward sign language and competence of teachers and other caregivers in…

The history and development of various sign languages in Europe and America are described, and the characteristics of manual communication systems are discussed. Modifications of sign language have been used to communicate with nonvocal austic children, severely language-delayed children, and retarded adults. (CTM)

A program was implemented to increase the manual signing of five profoundly retarded (mean age, 19 years) and four autistic (mean age, 9 years) youth within their daily environment. (Author)

Motivational factors and unique characteristics of sign language systems are suggested as contributing to the ability of severely dysfunctional nonverbal children to make progress within a manual communication medium. (Author/EJS)

Twenty-one nonverbal autistic children, 4- to 9-years-old, with language ages of 4- to 24-months, participated in the communication learning program from 1 to 3 years. Simultaneous verbal and manual signs were chosen as the communications mode. The children initially displayed infrequent, unrecognizable vocalizations (Screeches, or vocal…
