Abstract: | 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. |
