Abstract
Abstract Previous research (Reitan & Wolfson, 1995) has shown that age and education have a definite relationship among controls to scores on the General Neuropsychological Scale (GNDS), but minimal relationships among brain-damaged subjects. The present study investigated age and education relationships to WAIS VIQ, PIQ, and FSIQ values in brain-damaged and control groups, recognizing that these scores might differ from the GNDS in their sensitivity to brain damage as well as in their relationships to attribute variables. The findings yielded a complex set of results, with brain-damaged and non-brain-damaged groups being similar in some respects but different in others. In general, the results caution against the common practice of adjusting WAIS scores of brain-damaged subjects for age and education when the bases of the adjustments have been derived from non-brain-damaged controls.
