Long Term Memory in Normals and Retardates.
McLaughlin, John A.; Stephens, Will Beth
The study sought to determine if relationships existed among Piagetian measures of reasoning and memory, and if development of the memory process in normals and retardates is identical. Subjects were 48 normals (IQ 90-110) and 48 retardates (IQ 50-75), all CA 8-20 years. A battery of assessments, including conservation, spatial imagery, and memory tasks, was presented on three recall occasions. The first time, an arrangement of geometric shapes was shown to subjects, who were then asked to draw the configuration from memory. One week and 6 months later, subjects were asked to draw from memory then reconstruct from a random assortment the configuration. While normals performed better on all recall occasions, over 6 months the rate of decrement on both memory assessments (reconstruction and evocation) was the same for both groups, suggesting that a short term memory deficit evidenced in immediate recall is the major differentiator between normals and retardates. Analysis also indicated that both Piagetian measures of reasoning and standard measures of intelligence (WISC or WAIS) added to the prediction of memory, with the Piagetian reasoning measures the most efficient predictors.
