The study assessed effects of a transfer of stimulus control procedure on acquisition and cross-setting generalization of manual signs with four profoundly retarded young adults. Results showed that individuals acquired the trained signs and maintenance and generalization across settings and persons occurred but was highly variable between and…

Evaluation of a program which taught six severely mentally retarded individuals (ages 8-25) to sign interactively with each other found participants showed increased signing skills in a training play situation, generalized use of these skills in a second play situation, and maintained the trained skills over a 2 to 4 month period.

This study of four moderately to severely aphasic subjects found that success in manual sign training programs is related to severity of aphasia, that aphasic subjects' propositional use of manual signs rarely follows simple acquisition, and that generalization to untrained stimuli or environments does not occur without additional training.…

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)

Four adults with moderate/severe disabilities were taught to request objects by using the manual signs "want" or "please" plus an object label sign, within the context of familiar activities in which needed objects were missing. All participants acquired a generic requesting response, and three acquired an explicit requesting…

Verbal prompts, modeling, physical guidance, positive reinforcement, fading, and chaining procedures were used to teach two nonverbal individuals (one severely and one moderately mentally retarded) an interactive signing dialogue in a naturalistic setting. Although clients learned to use signed communication, extensive training was required and…
