This study aimed to address the need for a comprehensive assessment tool to evaluate the mathematical abilities of first-grade students through cognitive diagnostic assessment (CDA). The primary challenge involved in this endeavor was to delineate the specific cognitive skills and sub-skills pertinent to first-grade mathematics (FG-M) and to…

The Cattell-Horn-Carroll (CHC) taxonomy of cognitive abilities married John Horn and Raymond Cattell's Extended Gf-Gc theory with John Carroll's Three-Stratum Theory. While there are some similarities in arrangements or classifications of tasks (observed variables) within similar broad or narrow dimensions, other salient theoretical features and…

Wechsler Intelligence Scale for Children (WISC) is widely used to estimate autistic intelligence (Joseph in The neuropsychology of autism. Oxford University Press, Oxford, 2011; Goldstein et al. in "Assessment of autism spectrum disorders." Guilford Press, New York, 2008; Mottron in "J Autism Dev Disord" 34(1):19-27, 2004).…

The selection and interpretation of individually administered norm-referenced cognitive tests that are administered to culturally and linguistically diverse (CLD) students continue to be an important consideration within the psychoeducational assessment process. Understanding test directions during the assessment of cognitive abilities is…

The representativeness, recency, and size of norm samples strongly influence the accuracy of inferences drawn from their scores. Inadequate norm samples may lead to inflated or deflated scores for individuals and poorer prediction of developmental and academic outcomes. The purpose of this study was to apply Kranzler and Floyd's method for…

This article provides guidelines for an entry-level course that prepares psychology students and practitioners to acquire entry-level skills, abilities, knowledge, and attitudes important to the individual assessment of intellectual abilities of children and youth. The article reviews prominent international, regional, and national policies,…

Whenever a major intelligence or achievement test is revised, there is always renewed interest in the underlying structure of the test as well as a renewed interest in the scoring, administration, and interpretation changes. In this interview, Amy Gabel discusses the most recent revision of the "Wechsler Intelligence Scale for Children-Fifth…

The Wechsler Abbreviated Scale of Intelligence, Second Edition (WASI-II; Wechsler, 2011), published by Pearson, is a newly updated abbreviated measure of cognitive intelligence designed for individuals 6 to 90 years of age. Primarily used in clinical, psychoeducational, and research settings, the WASI-II was developed to quickly and accurately…

Adaptations of the Wechsler Intelligence Scale for Children Revised Performance scales for 127 deaf children revealed insignificant differences compared to norms for hearing children. A significant variation was noted within the subtests of deaf subjects of hearing parents: weakness of picture arrangement and coding with relative strength in…

A previous study on the underlying structure of the Wechsler intelligence test (WISC-R; [Wechsler, D. (1974). Manual WISC-R: Wechsler intelligence scale for children-Revised. New York: Psychological Corporation]), using smallest space analysis (SSA) [Guttman, L., and Levy, S. (1991). Two structural laws for intelligence tests.…

Examined the validity coefficients of all possible WISC-R short forms of several subtests. Comparisons were made between coefficients given by McNemar's and Silverstein's formulas to determine "best" short forms for different uses. Results indicated only a slight difference between short forms selected by the two methods. (Author)

Investigated robustness of the Wechsler Intelligence Scale for Children-Revised (WISC-R) factor structure. Comparisons of the loadings obtained with generalization sample and 10 1/2-year-old national standardization sample suggest high degree of similarity in composition, magnitude, and pattern. Findings highly support robustness of WISC-R's…

In this article, the author reviews the Wechsler Intelligence Scale for Children--Four Edition Spanish (WISC-IV Spanish), an individually administered measure of intelligence for Spanish-speaking children who are English language learners and relatively new to American culture. The WISC-IV Spanish, like its English counterpart, the WISC-IV, is…

Two structural laws for intelligence tests are discussed: one law concerns the sign of correlation coefficients and gives conditions under which all correlations between test items will be positive; and one law concerns the relative sizes of the correlation coefficients between intelligence items. A cylindrical structure extends these laws. (SLD)

Children aged 7 to 14 years were administered a computerized version of the Raven's Coloured Progressive Matrices test. Computer and traditional version performance was found to be similar in terms of total mean score, correlation with the WISC-R, Raven's subscale intercorrelations, and Raven's total mean score composition.
