Abstract
Noncollege deaf adults were compared with hearing controls on a series of 8 nonverbal learning and transfer or shift tasks which were designed to test an S's ability to combine previously discovered elements into new disjunctive and conjunctive groupings. In terms of total errors, successes, and trials to criterion, performance on these tasks was found to differentiate high from low IQ normal Ss and deaf Ss performed similar to hearing Ss on all tasks except one. These results would seem to refute the hypothesis that deaf people are generally inferior to hearing people in conceptual ability or that deaf children's experimental deficiency would leave a permanent lack in their conceptual development. The need for clarifying the role of language in cognition was stressed. (17 ref.)Preview Only. This article cannot be rented because we do not currently have permission from the publisher.
