Description
Summary:	The majority of researchers investigating the memory skills of retarded individuals have utilized heterogeneous samples of subjects whose sole criteria for grouping was either IQ or MA. The present experiment was designed to evaluate the short-term memory performance of subjects representing a specific type of retardation. Three groups of subjects (Down syndrome, CA control, and MA control) received a battery of tests designed to assess recall and recognition memory utilizing either auditory or visual input with verbal and nonverbal responses. Results indicated that the Down syndrome group possessed deficits in both storage and retrieval abilities, with storage of visually presented stimuli being particularly impaired.
