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…

The purpose of this study was to use multidimensional scaling (MDS) to investigate relations among scores from the standardization sample of the Wechsler Intelligence Scale for Children--Fifth edition (WISC-V; Wechsler, 2014). Nonmetric two-dimensional MDS maps were selected for interpretation. The most cognitively complex subtests and indexes…

Parents of gifted children are urged to understand that there are many different kinds of intelligence and ability tests; tests are designed for different purposes; all tests involve a certain amount of error; and tests only sample one aspect of a child's performance. (DB)

Samples in research on individual and group differences may be selected based on whole scores which differ from the population mean. Children are diagnosed in clinical practice with a whole score. These procedures produce regression to the population mean which can affect accuracy and adequacy of part score interpretations. (Author/DWH)

The paper provides a theoretical framework for the inclusion of a verbal intelligence test as part of the psychodiagnostic assessment battery used with deaf children. Descriptions are provided for three selected sign language varieties being used in a study designed to examine performance of 30 deaf children (9-16 years old) on signed…

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…

Forty-four educable mentally retarded students (12-16 years old) were given the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Wechsler Intelligence Scale for Children (WISC). (CL)

A report of a special panel, appointed by the Board of Scientific Affairs of the American Psychological Association, which investigates the use of ability tests with disadvantaged students in the schools, focusing especially on intelligence tests. Various sections present a discussion of the theoretical rationale of human abilities underlying the…

Discrepancies between the mental age (MA) scores and the mean performance of chronological age (CA) groups in the latest revision of the Stanford-Binet Intelligence Scale are noted. A table is presented for converting published Stanford-Binet MA scores into MA scores that are congruent with the above definition. (Author)

In this interview, Leon Kamin, a prominent psychologist, rejects the theory that intelligence is transmitted by heredity. He deplores the practice of finding scientific data to support political policies, and he challenges that standardized tests-as they are now used-create social harm. (Editor/PG)

Sattler's standard deviation technique for interpreting strengths and weaknesses on the Stanford-Binet Intelligence Scale has been simplified by Kaufman and Waterstreet in the form of an easy-to-use table. A refinement of their table is presented, with an example to demonstrate its use. (Author/CTM)

Score differentials between the revised Wechsler Intelligence Scale for Children (WISC-R) and the Wechsler Adult Intelligence Scale (WAIS) were investigated in 25 possibly mentally handicapped adolescents (10 white, 15 black). Each S was individually administered both the WISC-R and the WAIS. Results supported the hypothesis that for mentally…

Reports a study which investigated the influence of the variables of race (examiner and child race) and expectancy (high and low expectancy) upon the scoring of individual IQ tests. (Author/JM)
