Whitaker, Simon – Intellectual and Developmental Disabilities, 2008
A meta-analysis of the stability of low IQ (IQ less than 80) was performed on IQ tests that have been commonly used--tests that were derived by D. Wechsler (1949, 1955, 1974, 1981, 1991, 1997) and those based on the Binet scales (L. M. Terman, 1960; L. M. Terman & Merrill, 1972). Weighted-mean stability coefficients of 0.77 and 0.78 were found…

A comparison of the sample's mean scores indicates similar GAMA and WAIS-III Performance IQ scores. In contrast, the sample's mean GAMA IQ score was significantly lower than the sample's mean Full…

Analyzed published data on the Wechsler Adult Intelligence Scale (WAIS) to ascertain whether the Information and Vocabulary subtests can function as measures of intelligence. Concluded that the addition of more WAIS subtests will not result in any increase in predictive validity and these additional tests, therefore, lack incremental validity.…

Peer reviewedKaufman, Alan S. – School Psychology Quarterly, 1994
Explores alternative empirical foundations of verbal and performance dichotomous constructs of Wechsler Intelligence Scales. Argues that Macmann and Barnett's position on the value of these constructs are based upon narrow interpretations of investigative results. Supports contention with IQ data from investigations of diverse populations. (CRR)

Peer reviewedReid, J. M. V. – Journal of Visual Impairment & Blindness, 1997
Reviews research on ability testing for adults with visual impairments, especially the tests used for vocational assessment and counseling. The verbal scales of the Wechsler Adult Intelligence Scale-Revised were found to be widely accepted. The problems, however, with relying solely on verbal assessment are addressed, and the need for tests for…

Peer reviewedMatarazzo, Joseph D. – American Psychologist, 1990
Increasingly neuropsychologists are under pressure, particularly in child custody and personal injury litigation, to justify the validity of the tests upon which their assessments are based. Reviews research on the validity of clinical opinions based on tests and concludes that test scores must be used in conjunction with life history and current…
