Purpose: Children with neurodevelopmental disorders historically exhibit lower and more variable nonverbal intelligence (NVIQ) scores compared to their typically developing peers. We hypothesize that the intrinsic characteristics of the tests themselves, particularly the cognitive constructs they assess, may account for both the lower scores and…

Scores of 38 learning-disabled college students on the revised Wechsler Adult Intelligence Scale (WAIS-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) were compared. Results indicated significant correlations between the tests, though subjects tended to obtain higher scores on the WISC-R than on the WAIS-R. (Author/DB)

The position that intelligence and achievement are essentially different measures of the same construct has often been referred to as a "jangle fallacy." Such a position challenges the present practice of placing children in learning disabilities programs based on a discrepancy between Intelligence Quotient (IQ) and achievement. This…

Comparison of Wechsler Intelligence Scale for Children (WISC)-Revised and WISC III IQs for 64 students with specific learning disabilities and 55 students with mental retardation (MR) found that correlations were lower than those reported in the WISC-III manual. Only Performance IQs for students with MR matched the correlations reported in the…

The longitudinal stability of the Wechsler Intelligence Scale for Children-Revised was examined for consistency in determining eligibility for gifted programs among 66 elementary children. All subtest scales except one remained extremely stable, producing less than one scale score point difference across three test administrations. Children…

This study examined differences between Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 40 elementary students with learning disabilities. WISC-III Full Scale, Verbal, and Performance scores were lower than comparable WISC-R scores by one-third to one-half a…

The stability of intelligence test scores over time was examined for the Wechsler Intelligence Scale for Children-Revised (WISC-R). Subjects included 64 children aged 6-16, who had been administered the WISC-R during prior evaluations. These students had been referred because of academic difficulties. One-third of the sample had taken the test…

A study of 33 elementary/middle school deaf children correlated Wechsler Intelligence Scale for Children-Revised Performance Intelligence Quotients (IQs) with Stanford Achievement Test-Hearing Impaired Edition (SAT-HI) grade equivalents and age-based percentiles. A second study of 64 children correlated nonverbal IQs from many tests with SAT-HI…

A table is provided for determining the frequency of occurrence of Verbal-Performance discrepancies on the Wechsler Intelligence Scale for Children-Revised (WISC-R) in profiles of high Intelligence Quotient children. Warnings are offered regarding the adverse effect of subtest substitution or omission when administering the WISC-R to highly…

The purpose of this study was to replicate previous factor analytical studies of the Wechsler Intelligence Scale for Children-Revised (WISC-R) employing children identified as gifted. However, rather than using the IQ criterion, a child's 11 WISC-R subtest scores were included in the analysis. Subsamples of gifted (as classified by local school…

The factor structure of the Wechsler Intelligence Scale for Children (Revised) was examined in the standardization sample using new methods of factor analysis. The substantial overlap across factors was most parsimoniously represented by a single general factor. Implications for public policy regarding the purposes and outcomes of special…

The study examined the efficacy of familiarity and positive verbal reinforcement in improving intelligence test scores of 48 third-graders who were low scorers on a previous test. The Quick Test was used to screen subjects, with a 90 IQ score being the criterion for inclusion in the study. Subjects were randomly assigned to one of four groups. The…

This study investigated the construct validity of five perceptual traits (auditory discrimination, visual discrimination, visual memory, visual-motor coordination, and auditory to visual-motor coordination) with five simulated work samples (union assembly, resistor reading, budgette assembly, lock assembly, and nail and screw sort) from the Jewish…

The constancy of intelligence quotients (IQs) of 161 gifted Israeli children, obtained initially in grades K-4 and retested 1-4 years later, was examined. Results indicated that 86% still qualified as gifted on the retest, with mean differences of five to eight IQ points. Performance scores tended to remain constant, whereas verbal scores tended…

Comparisons of Wechsler Intelligence Scale for Children-Revised scores, for 24 children with learning disabilities demonstrating a low verbal, high performance intelligence quotient (IQ) discrepancy and 33 slow learning children having uniformly low verbal and performance IQs, revealed few cognitive differences beyond the Performance Scale…
