A brief discussion of theories of general intelligence precedes a report of relevant empirical data. Results from the factor analysis of more than 20 sets of Wechsler Adult Intelligence Scale (WAIS) data indicate that the WAIS clearly is not a one-factor scale. It does not measure a single, general intelligence. Roughly 17 percent of the reliable…

The research concerning intellectual functioning in addict populations has not addressed basic questions concerning why and how intelligence quotients (IQ) might be related to drug addiction. A study was undertaken to estimate intellectual functioning based upon a demographic profile for Wechsler Adult Intelligence Scale-Revised (WAIS-R) Full…

The classification of intelligence has been a prime interest to many for over three-quarters of a century. The Wechsler scales of intelligence and the development of factor analysis have both played major roles in the shaping of psychometric thought. An examination of this joint history by means of a review of the factor analytic studies of the…

Performance on the Digit Span (DSP) and Digit Symbol (DSY) subtests of the Wechsler Adult Intelligence Scale (WAIS) have been said to be vulnerable to the effects of anxiety, seating arrangements, and sex of subject. To determine the effects of these variables on anxiety and test performance on the WAIS-R DSP and DSY subtests, 40 male and 40…

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…

The effects of family background on adolescents' IQ, aptitude, and school achievement test scores challenge some of the usual beliefs about the fairness of achievement rather than IQ tests, and the role of genetic differences among individuals and social class groups in academic achievements. Subjects included 115 adoptive families with adolescent…

An important reaction to individuals involved in problem solving is detecting the accuracy of their responses. Prior research has established that young adults are accurate in estimating correctness to responses on the Wechsler Adult Intelligence Scale (WAIS). These findings were extended to the elderly; also considered was whether…

To examine the issue of item bias within the context of the revised Wechsler Adult Intelligence Scale (WAIS-R), judgments as to perceived item bias were sought. Independent raters nominated 53 WAIS-R items as containing possible bias. White and non-white college students nominated items as racially or sexually biased. Whereas 10 items were judged…

This paper presents a study regarding the correlation of the Stanford-Binet: 4th Edition Intelligence Quotient (IQ) scores with the Wechsler Adult Intelligence Scale-Revised (WAIS-R) IQ scores for the purpose of improving the identification process for educable mentally handicapped (EMH) school age adolescents and young adults. The sample included…
