Research has indicated that school aged (6-16 years) versions of cognitive assessment instruments have varying levels of linguistic demand, which could impact assessment results for placement purposes. However, a significant limitation to this research is the fact that it has not been replicated with cognitive assessment instruments used in…

The current study provides a methodological review of studies supporting a general factor of intelligence as the primary model for contemporary measures of cognitive abilities. A further evaluation is provided by an empirical evaluation that compares statistical estimates using different approaches in a large sample of children (ages 9-13 years, N…

Surveys reveal that many school psychologists continue to employ cognitive profile analysis despite the long-standing history of negative research results from this class of practice. This begets the question: why do questionable assessment practices persist in school psychology? To provide insight on this dilemma, this article presents the…

Sex differences in the latent general and broad cognitive abilities underlying the Woodcock-Johnson Tests of Cognitive Abilities were investigated for children, youth, and adults ages 6 through 59. A developmental, multiple indicator-multiple cause, structural equation model was used to investigate sex differences in latent cognitive abilities as…

Evaluated correlations between Wechsler Intelligence Scale for Children-Revised, Woodcock-Johnson (W-J) Achievement clusters, Woodcock-Johnson Aptitude clusters, and Broad Cognitive Ability Score in 60 Behavior-Disordered male adolescents. Aptitude cluster scores had insufficient validity to justify computation for population; Broad Cognitive…

Reports the results of the first joint confirmatory factor analysis (CFA) of the Cognitive Assessment System (CAS) and the Woodcock-Johnson Tests of Cognitive Abilities-3rd Edition (WJ III). Results of these analyses do not support the construct validity of the CAS as a measure of the PASS (planning, attention, simultaneous, and sequential)…

First graders (N=26) completed the Wechsler Intelligence Scale for Children-Revised, McCarthy Scales, and Woodcock-Johnson Scales of Cognitive Ability. Two years later, their academic achievement was determined by Wide Range Achievement Test and teacher ratings. Results suggest that all three intellectual measures are appropriate for predicting…

The study provides descriptive data on use of the Woodcock-Johnson Tests of Cognitive Ability with 39 adults with closed head injury. Correlational analyses indicated significant relationships between coma duration and performance on the Perceptual Speed and Memory clusters of the test. Time since injury did not correlate with test results.…

Administered the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) to educable mentally retarded children (N=30). Results showed significant mean differences between WISC-R and WJTCA full-scale standard scores, providing implications for placement of children in classes for the…

Three new tests presented as alternatives to the Wechsler tests for children were described in earlier papers of this session. This discussion reviews the earlier papers and comments on the developed tests: (1) the Woodcock-Johnson test; (2) the new Stanford-Binet; and (3) the K-ABC. The Woodcock-Johnson battery, state-of-the-art applications of…

Compares the performance of learning disabled students on the WISC-R and the Tests of Cognitive Abilities from the Woodcock-Johnson Psycho-Educational Battery. This study finds that learning disabled subjects performed more poorly on the Tests of Cognitive Abilities than on the WISC-R. (Author)

Compared the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) score profiles of different cultural groups, using 442 White and 435 non-White subjects drawn from the kindergarten through grade 12 subset of WJTCA standardization data. Determined that data allowed for classification of the subtests by both curve and cultural effects criteria.…
