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…

Age differences in intellect as reflected by performance on the Wechsler Adult Intelligence Scale (Revised) (WAIS-R) were evaluated for persons aged 20 to 74 years. Educational attainment levels were held constant. The WAIS-R sample included 1,480 men and women in the following seven age groups--20-24 years (n=250), 25-34 years (n=250), 35-44…

Intelligence quotient (IQ) differences among groups according to sex, and demographic and other variables have been explored for a variety of intelligence tests. This investigation analyzed data from the standardization sample for the 1981 Wechsler Adult Intelligence Scale-Revised (WAIS-R) to determine the relationship of WAIS-R IQs to the…

Multivariate methods were used to identify between-set factors relating the criterion set of eleven Wechsler Adult Intelligence Scale Revised subtest variables to the predictor set of demographic variables: age, race, sex, education, occupation, geographic region, and urban versus rural residence. Although factor analysis is usually used to…

In this study, cognitive processes hypothesized to be relevant to the digit symbol task of the Wechsler Adult Intelligence Scale (WAIS) were examined. Fifty-two undergraduate education students were divided into four groups to receive four different treatments. All the students took the digit symbol test, followed immediately by a test of their…
