Evaluated the extent to which the Graduate Record Examinations General Test measures the same constructs for older test takers that it does for younger examinees. Results suggest that the convergent validity of the test is similar across the age groups, but discriminant validity is somewhat different for older examinees. (Author/RWB)

The joint factor structure of the Differential Abilities Scale (DAS) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) was investigated with 115 normal children (ages 8-15). Analysis supported the DAS structure and the WISC-III four-factor reinterpretation of the WISC-R. (Author/DB)

A factor analysis was conducted for a sample of 200 white and Hispanic children (ages 6-11) using the Wechsler Intelligence Scale for Children-Revised. Results indicated that the two-factor solution was similar for the two groups, but there were notable differences for the three-factor solution, relative measures of "g," and subtest…

The Chinese revision of the Wechsler Adult Intelligence Scale was factor analyzed for 55 Chinese subjects with mental retardation. Results indicated a two-factor solution comprising Verbal Comprehension and Perceptual Organization factors. Analysis found no important differences in factor structure between the Chinese subjects and low-intelligence…

The classification of intelligence has been a prime interest to many for over three-quarters of a century. The Wechsler scales of intelligence and the development of factor analysis have both played major roles in the shaping of psychometric thought. An examination of this joint history by means of a review of the factor analytic studies of the…

Multivariate methods were used to identify between-set factors relating the criterion set of eleven Wechsler Adult Intelligence Scale Revised subtest variables to the predictor set of demographic variables: age, race, sex, education, occupation, geographic region, and urban versus rural residence. Although factor analysis is usually used to…

A confirmatory factor analysis was used to determine the respective viability of factor structure models for the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization data. The traditional verbal-performance split was compared to an alternative model proposed by Gutkin, Reynolds and Galvin. The confirmatory analysis indicated that the…

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…

This study evaluated the construct validity of the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) with children (ages 8 to 13) having learning disabilities who were either Hispanic (N=120) or Non-Hispanic white (N=120). Factor analyses found that the WISC III has a three factor structure consisting of verbal comprehension,…

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…

Describes a study of 323 fifth and sixth grade students which was conducted in Australia to examine cognitive processing of gifted children compared with normal and above average ability children. Highlights include the role of planning in cognition, tests used, and a factor analysis of results. Fifty-one references are listed. (Author/LRW)

Factor analysis performed on the Wechsler Intelligence Scale for Children-Revised (WISC-R) for 252 subjects (ages 6-16), who were mentally handicapped, slow learners, or learning disabled, identified 3 factors: verbal-conceptual, perceptual-spatial, and distractibility-short-term memory. Findings suggest that the factor example can be used to…

This study, with 161 children with and without language learning problems, tested the hypothesis that as children's language development matures, factor-analytic structural changes occur that are associated with measurements of fine-grained auditory discrimination, receptive vocabulary, receptive language, speech production, and 3 performance…

Students (n=300) referred for special education and diagnosed as learning disabled, mentally retarded, or not eligible were examined to determine the differential contribution of sociocultural variables on eligibility decisions within the context of intelligence test factors. Factors analyzed included verbal comprehension, perceptual organization,…

Tests of spatial ability were analyzed for their analog (visuospatial) and nonanalog (verbal reasoning) components, using factor analyses of items and test scores. The self-selected sample consisted of over 2000 clients (average age about 26 or 27) employing the Johnson O'Connor Research Foundation's aptitude evaluation services in 12 metropolitan…
