Effects of unilateral lesions of the Wechsler Memory Scale

Compared 10 Ss with confirmed unilateral lesions in the right or left hemisphere on subtests of the Wechsler Memory Scaler (WMS). The groups were comparable in terms of age, sex, education, Full Scale IQ and Memory Quotient. Contrary to previous studies, it was found that the WMS was sensitive to the effects of unilateral lesions when the pattern of deficits on the subtests was examined. The same subtests that have been shown to discriminate between controls and brain-injured Ss also were sensitive to unilateral lesions.
