Explores alternative empirical foundations of verbal and performance dichotomous constructs of Wechsler Intelligence Scales. Argues that Macmann and Barnett's position on the value of these constructs are based upon narrow interpretations of investigative results. Supports contention with IQ data from investigations of diverse populations. (CRR)

Discrepancy scores (Verbal IQ minus Performance IQ) were examined for the WISC-R, using the standardization sample as the data source. The occurrence of significant discrepancy scores was found not to be significantly related to age, sex, or race, although significant relationships were obtained with both parental occupation and intelligence…

Wechsler Preschool and Primary Scale of Intelligence (WPPSI) Verbal, Performance and Full Scale IQ's were compared for blacks and whites (matched in age, sex, geographic region, father's occupation, and urban-rural residence). Although whites had significantly higher verbal and Full Scale IQ's at all age levels, Performance IQ was significantly…

A comparison was made of the intellectual ability of groups of black and white children--ages 4 to 6---who were matched on various demographic variables. The aim of the study was to examine the comparative performance of the children on the Wechsler Preschool and Primary Scale of Intelligence in order to observe any emergent patterns across the…

The reliability and validity of three short forms of the Wechsler Intelligence Scale for Children III (WISC-III) were compared. Each of the short forms was a tetrad composed of two verbal and two performance subtests. The first tetrad was selected based primarily on practical considerations, particularly its brevity to administer and score. The…
