Auditory and visual memory span: cognitive processing by TMR individuals with Down syndrome or other etiologies.
Auditory and visual memory span for letters and component memory processes of TMR young adults with Down syndrome or other etiologies was examined. Component processes of the span task included long-term memory access for labels for the stimuli and memory for the order in which the stimuli were presented. Results indicated that although all subjects had relatively poor auditory memory spans, the Down syndrome group was especially poor at long-term memory access for stimulus identification and at short-term storage and processing of auditory information. Lexical storage and retrieval deficiencies were isolated, accounting for the verbal difficulties experienced by the individuals with Down syndrome, leading to their deficiency in processing lexical information.
