The Visual Reproduction Subtest: Standardization and Clinical VaIidation of a Delayed Recall Procedure

This study provided a normative data base for a Delayed Recall procedure using the Visual Reproduction subtest from Form I of the Wechsler Memory Scale and examined the test's clinical sensitivity in four groups of patients. Normative data were based on 255 neurologically normal adults (age range 18-91). Clinical groups included patients with severe head trauma (n = 34), left hemisphere CVA (n = 13), right hemisphere CVA (n = 43), and Alzheimer's Disease (n = 13). Analysis of normative data revealed significant age related differences, with older subjects performing lower on both Immediate and Delayed Recall tasks. Group data revealed that patients in all four clinical groups performed significantly below age matched controls. Further analyses revealed that Visual Reproduction scores correlated positively with measures of visual-spatial ability and verbal memory, as well as with other visual memory measures.
