Abstract
Administered the WAIS-R to 89 patients (mean age 42 yrs) with neurodiagnostically confirmed unilateral or bilateral cerebral disease. Similar to findings with previous editions of these tests, Ss with left-hemisphere disease obtained significantly lower Verbal IQ (VIQ) than Performance IQ (PIQ), and Ss with right or bilateral disease obtained lower PIQ than VIQ. It is cautioned that these VIQ-PIQ discrepancies in isolation are ineffective indexes of cerebral dysfunction and that patterns of performance must be viewed in the context of a complete neuropsychological examination and relevant medical and educational historical data.
