Generalization of a sign language rehearsal strategy in mentally retarded and hearing deficient children.
Memory deficits are common in mentally retarded individuals who lack verbal skills. Training in manual signing may be of value. In this study we trained a sign language rehearsal strategy so that the strategy would be used with no instructions to perform it; and assessed whether the strategy would transfer across tasks, and how to train for transfer. Subjects were five essentially nonverbal severely mentally retarded children and three essentially nonverbal deaf children. Each was trained to use a sign-rehearsal strategy in one of two memory tasks. Use of the strategy showed marked increases when children were instructed to rehearse, but showed less change when no instructions were given. Generalization to uninstructed trials was then achieved by gradually delaying the instructions. After this training, two of three children trained in a more complex task transferred uninstructed sign-rehearsal to a less complex task, but children trained in the simpler task did not generalize to the complex task.
