Manual Sign Training for Nonverbal Severely Retarded Adolescents. Final Report.
Bray, Norman W.; Thrasher, Kenneth A.
Twenty-four severely mentally retarded adolescents (with no uncorrected visual or hearing losses) were trained to use 16 manually signed English signs. Ss were randomly assiged to sign only, or sign plus speech conditions and performances were videotaped. Analysis of results revealed that all Ss learned some signs to criterion and all showed performance gains on most signs. Failure to form given signs correctly appeared to be largely ideosyncratic. Contrary to hypotheses, no learning differences were found between iconic and abstract signs. A substantial part of the document reviews the literature on remedial vocal training and nonspeech communication systems for mentally retarded persons. Animal signing studies are further analyzed, as are implications of signing language training with autistic children. (CL)
