The Relationship between Processing Rate and Memory Span in Learning Disabled Children.
Lorsbach, Thomas C.; Gray, Jeffrey W.
The study attempted to further clarify the relationship between speed and memory span by directly examining whether slower identification of item information is the source of span difficulties in learning disabled (LD) children. Forty-eight sixth grade boys participated in the study, 24 LD and 24 non-LD. The method involved pretesting each subject to obtain mean naming latencies for each of 8 classes of stimuli. The experimental procedure then presented each S with two memory span tasks: one using stimuli that had produced comparable group naming latencies, and the other with a stimulus class that had produced significant group differences in naming speed. The results indicated that span performance varied directly with naming speed. Results were discussed within the working memory framework of A. Baddeley and G. Hitch (1974), and it was concluded that a causal relationship exists between item identification speed and memory span performance. (Author/CL)
