Abstract
Verbal-Performance IQ discrepancies on the WAIS [Wechsler Adult Intelligence Scale] are of much interest to clinical psychologists. They are related, among other things, to different types of brain damage and in studies of the mentally subnormal, to successful adjustment to the outside world. Such discrepancies obtained by patients in a hospital for the mentally subnormal were studied. These discrepancies are both frequent and related to full scale IQ. The pattern that emerges remains constant if scaled scores are considered or if the subtests are re-arranged according to Cohen''s A and B factors. These findings imply caution in the use of the discrepancy measure as a diagnostic or predictive indicator in this population.
