Differential sensitivity of the WMS to the effects of IQ and brain damage.
The sensitivity of the Wechsler Memory Scale with Russell's Revision to the effects of IQ and brain damage was assessed in groups of brain-damaged (N = 64) and nonbrain-damaged (N = 64) subjects. Brain-damaged and nonbrain-damaged subjects were divided into subgroups equated on age and IQ for each of three IQ ranges (80-89, 90-99, 100-109). Some Wechsler Memory Scale subtests were affected only by IQ, others were affected by IQ and brain-damage status, and still others were affected only by brain-damage status. Measures of recall efficiency were most useful in discriminating brain-damaged and nonbrain-damaged subjects. We concluded that specific Wechsler Memory Scale subtests are useful in assessing memory deficits in brain-damaged patients.
