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…

Consideration of the influence of English language skills during testing is an understandable requirement for fair and valid cognitive test interpretation. Several professional standards and expert recommendations exist to guide psychologists as they attempt to engage in best practices when assessing English learners (ELs). Nonetheless, relatively…

Intelligence testing was one of the earliest interests of psychologists in India. Adaptation of Western intelligence tests has been a focus of psychologists in the first half of the last century. Indigenous development of intelligence tests has been attempted, but diversity of language and culture, complexity of school systems, and infrastructural…

This article briefly reviews the history of intellectual assessment of children and youth in the United States of America, as well as current practices and future directions. Although administration of intelligence tests in the schools has been a longstanding practice in the United States, their use has also elicited sharp controversy over time.…

Changes in the full scale reliability of the WISC-R were computed at three age levels when each subtest was omitted by itself. The same procedure was followed with those subtests which independently had the smallest effect in lowering full scale reliability. Cautions were noted concerning the exclusion of subtests. (Author)

Discusses the changes in psychological testing and the rapidity of their development. Describes trends in the role of the test user, technical methodology of test construction, and interpretation of test scores. (Author)

Data from 255 normal individuals were factor analyzed. Variables included subtests from the Wechsler Adult Intelligence Scale-Revised (WAIS-R), the Kaufman Adolescent and Adult Intelligence Test (KAIT), and two new brief measures. Results are interpreted in the context of previous Horn analyses of the KAIT and WAIS-R. (SLD)

The factor structure in this study was remarkably consistent across the age range, with three factors emerging for each group: Verbal Comprehension, Perceptual Organization, and Freedom from Distractibility. The results of the study are discussed in terms of their clinical applications, particularly interpretation of WISC-R profiles. (Author)

WISC performance of Jewish children has revealed a highly consistent and stable pattern, characterized by relatively low scores on Picture Completion, Picture Arrangement, Block Design, and Object Assembly. Some of these findings might be understood by reference to relative weakness of Jewish subjects on tasks related to psychological…

Disadvantages of traditional intelligence tests with handicapped children are discussed, and an alternative approach, The "Assessment of Basic Competencies" (ABC) is presented. The background and design of the ABC and the three domains of the model (language skills, math reasoning skills, and information processing skills) are…

Revised version of the 1973 presidential address to the American Educational Research Association. (RJ)

Reappraises the validity and reliability of Vocabulary and Block Design (V-VD) as a short form of the Wechsler Adult Intelligence Scale (WAIS), the Wechsler Intelligence Scale for Children (WISC), and the Wechsler Preschool and Primary Scale of Intelligence (WPPI). Presents a table for converting the sum of scaled scores into an estimate of Full…

The measurement of intelligence (I.Q. testing method) has been based on test item construction methods that set norms for mental levels. Individual performance levels are determined by the distribution of scores based on the total group or mean score. The problem with this method of assessment for research purposes is that idiosyncratic…

The advantages of using psychometric thoery to design short forms of intelligence tests are demonstrated by comparing such usage to a systematic random procedure that has previously been used. The Wechsler Intelligence Scale for Children Revised (WISC-R) Short Form is presented as an example. (JKS)

The Wechsler Intelligence Scale for Children-Third Edition (WISC-III) is an individually administered test of intelligence for assessing children aged 6 through 16 years, 11 months. The WISC-III consists of several subtests, each classified into a verbal or performance scale. The child's performance on these measures is summarized in three…
