Violent Delinquency, Race, and the Wechsler Performance-Verbal Discrepancy
Examined the relationship between Wechsler Adult Intelligence Scale (WAIS) Performance (P) and Verbal (V) IQ scores and levels of violent delinquency in 67 White and 58 Black juvenile probationers. Data indicate that (1) P > V discrepancy scores can differentiate between group means on violent behavior, (2) the inclusion of race in the analysis does not diminish the effect of P > V, and (3) Blacks may be significantly underrepresented among high P > V scorers.
