Studied whether Stanford-Binet Intelligence Scale: Fourth Edition corresponds to theory that guided its construction, using first-order confirmatory factor analysis with entire standardization sample and three age groups. Results generally support the four factors as reflecting the underlying structure of the new Binet, but were less supportive of…

Investigated the overlap between the Wechsler Intelligence Scale for Children - Revised (WISC-R) and the Halstead-Reitan Neuropsychological Battery (HRNB) in light of their use in diagnosing children's learning problems using scores for children (N=1,181) on the WISC-R and the HRNB. Results showed primary overlap between measures was attributed to…

Investigates the general factor and uniqueness characteristics of the individual tests of the Woodcock-Johnson Test of Cognitive Ability-Revised (WJTCA-R). Only 2 of the 19 WJTCA-R tests examined had low general factor loadings, while 2 had low uniqueness. All other tests had medium or high uniqueness. Discusses implications for clinical…

Examines the performance characteristics of 83 school-identified learning-disabled children on the Differential Ability Scales. Sixty percent showed a significant standard score discrepancy between the General Conceptual Ability and at least one achievement test. Implications regarding the educational diagnostic and intervention processes…

Notes that significantly different results frequently exist between tests that purport to measure the same skill when the same child is tested on both instruments. Considers discrepancies related to examinee, examiner, examinee-examiner interactions, environment, and psychometric characteristics of the tests employed. Cites 10 major psychometric…

Employed two strategies used to test prerequisite relationships among intellectual skills to examine the sequence of three types of subtraction tasks. A psychometric validation strategy yielded results similar to instructional validation strategy. Supports the use of the more efficient psychometric approach for validating large numbers of learning…

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.…
