“…Because of this lateralized representation, the direction of the discrepancy may be useful for making diagnostic hypotheses about lesion loci. Guertin, Ladd, Frank, Rabin, and Hiester (1966) reviewed a number of studies suggesting that lower PIQ stores are indicative of righthemisphere pathology, whereas lower VIQ scores are indicative of damage to the left hemisphere, findings that are in agreement with the earlier reports of Reitan (1955) and of Klove and Reitan (1958). More recently, Uzzell, Zimmerman, Dolinskas, and Obrist (1979) reported differential effects on VIQ and PIQ scores corresponding to lateralization of intracranial hematoma or hemorragic contusion.…”

This study examined children from an unselected birth cohort who had Wechsler Intelligence Scale for Children-Revised (WISC-R) verbal and performance IQ discrepancies that placed them beyond the 90th percentile. It was hypothesized that, relative to their cohort peers, these children would be characterized by greater frequency of perinatal difficulties, early childhood neurological abnormalities, health problems of neurological significance, and concussion. Additionally, it was hypothesized that such children would exhibit more behavior problems, lower academic achievement, and poorer motor skills. Generally, the null hypotheses were not rejected by the results. Longitudinal investigation of the stability of the verbal and performance IQ discrepancy revealed that about 23% of discrepant cases were discrepant at two or more ages. Depressed verbal IQ relative to performance IQ was found to be more common than the reverse pattern. Children with performance IQ greater than verbal IQ scored significantly lower than children for whom this pattern was reversed on measures of academic achievement. Results show that cautious interpretation is needed of verbal and performance IQ discrepancy in the general (nonneurological) assessment setting.

“…However, the significance of and even the generality of this finding have been subject to controversy (Fernald & Wisser, 1967;Guertin, Ladd, Frank, Rabin, & Hiester, 1966). While it seems that the Performance (P) > Verbal (V) sign should not be considered diagnostic of delinquency, it does represent one part of the cognitive or intellectual processes often associated with delinquency.…”

A sample of 55 black and white male delinquents was randomly assigned to take either the Wechsler Intelligence Scale for Children-Revised (WISC-R) or Wechsler Adult Intelligence ScaleRevised (WAIS-R). The two tests did not show significant differences in mean Verbal, Performance, or Full Scale IQs, but a test by race interaction consistently suggested that the scores of blacks were lower on the WISC-R than on the WAIS-R disproportionately to whites. Greater mean Performance IQ minus Verbal IQ differences were seen on the WISC-R than on the WAIS-R, and frequency analysis revealed a greater number of youths with a significant Performance minus Verbal difference on the WISC-R. These results suggest that use of the WAIS-R may be preferable to use of the WISC-R in 16-year-old delinquent males, and the possibility of relative racial bias in the WISC-R should be considered.

“…After a review of the VIQ-PI& difference literature, Guertin, et al ( 3 ) concluded in essence that with the exception of possible use with brain-damaged clients, VIQ-PI& differences have minimal, if any, value in individual psychological assessment. Recently, Matarazzo (13) has offered a similar criticism of WAIS profile analysis, such as VIQ-PI& differences.…”

Verbal and performance IQ for discrimination among psychiatric diagnostic groups

WAIS Verbal and Performance IQ scores were obtained from medical records of 500 psychiatric inpatients recently admitted to a large university hospital. With a subsample of the original 500 patients for whom there was diagnostic agreement between two independent clinicians, a multivariate analysis of variance was carried out to determine the extent to which the Verbal and Performance scores discriminated among eight diagnostic categories into which patients were classified. In the multivariate ANOVA, statistical techniques were employed to control for concomitant background variation that otherwise might have been confounded with true diagnostic group differences in Verbal and Performance IQ. Although mentally retarded and organic brain syndrome patients could be distinguished significantly from other diagnostic groups on the basis of their lower total IQ scores, the data did not support the persistent clinical belief that functional psychiatric disorders differed in the WAIS measurement space.
