Availability and Accessibility of Information in the Semantic Memory of Retarded and Nonretarded Adolescents.
Glidden, Laraine Masters; Mar, Harvey H.
The availability of semantic information in storage and the accessibility of that information for retrieval was studied with 40 retarded and 40 nonretarded adolescents. In Experiment I, Ss were required to retrieve information from semantic categories, as well as judge whether specific items were members of a given category. Results showed that retarded Ss retrieved only about 60% of the total number of items retrieved by nonretarded Ss, a difference which could not be wholly accounted for by the items available in storage. Experiment 2 was designed to remediate this retrieval deficit by introducing an organized retrieval plan consisting of subcategory cues. The organization facilitated retrieval as long as it was experimentally provided. Retrieval returned to its original level, however, when the cues were withdrawn. It was concluded that retarded individuals had an accessibility deficit in addition to an availability deficit; one aspect of this assessibility deficit involved the failure to spontaneously use mnemonic strategies that were consistent with the semantic organization.
