The discrepancies in WAIS Verbal and Performance IQs for a sample of 239 subjects with epilepsy were assessed. Both males and females had significantly higher mean Verbal IQs, but the magnitudes of discrepancy scores were only about half the amount noted by Pickering, et al. Individuals differed widely. It may be more fruitful to investigate the relationship between individual-difference variables and the inequality of Verbal IQ and Performance IQ than to apply the correction, proposed by Pickering, et al., of 5 points to equate the IQs.
