Data for the Raven's Advanced Progressive Matrices test from 3 large studies for a total of 818 adults show that although older adults perform like low-ability young adults when the measure of interest is the number correct, there does not seem to be an age-related difference in the type of reasoning used.

Introduces Stanford-Binet Intelligence Scale-Fourth Edition (SB4) as an attempt to revitalize Stanford-Binet by maintaining links with previous editions while simultaneously incorporating more recent developments found in other popular tests of intelligence. Discusses the SB4's theoretical foundation, materials and administration, scaling,…

A study concluding that the Wechsler Adult Intelligence Scale (Revised) (WAIS-R) has three clear factors in its structure is critiqued. An alternative factor comparison technique, FACTOREP, is used with identical data. It is demonstrated that the WAIS-R has only two strong factors--verbal comprehension and perceptual organization.

Wechsler Adult Intelligence Scale-Revised subtests, as administered to 204 adults with low IQs, were factor analyzed. Solutions proved comparable to structures extracted from the normative data and to solutions based on other standardized tests for persons with low IQs. (Author)

Criticizes "The Bell Curve" for its lack of understanding of the philosophical nature of intelligence (and mind). Points out that various philosophical attempts to analyze the concept of intelligence are routinely ignored by empirical workers in the field of IQ testing because such philosophical work makes obvious the lack of connection…

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)

A study of intercorrelations and long-term stabilities of Wechsler Adult Intelligence Scale-Revised, Wechsler Memory Scale-Revised, and Auditory-Verbal Learning Test indexes for 300 older adults challenges assumptions that for cognitively normal people, performance in one cognitive domain correlates well with others and that cognition is stable.…

Six hierarchical clustering methods were applied to subtest intercorrelations for each of the nine age groups in the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization sample. Results point to the possibility of three simultaneously plausible solutions as they support each of the traditional factor structures in varying degrees.…

Examined relationship between Wechsler Adult Intelligence Scale-Revised (WAIS-R) and Wide Range Achievement Test-Revised (WRAT-R) scores among 78 educable mentally retarded adolescents. Found that WAIS-R Verbal intelligence quotient (IQ) was significantly correlated with all WRAT-R subtests. Performance IQ was significantly related only to…

Examined concurrent validity between Woodcock-Johnson Psycho-Educational Battery-Revised Tests of Cognitive Ability (WJ-R, COG) (Early Development) and Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R) by administering instruments to 30 normal 3, 4, and 5 year olds. WJ-R Broad Cognitive Ability and WPPSI-R Full Scale IQ and…

Administered Stanford-Binet Intelligence Scale: Fourth Edition and Kaufman Assessment Battery for Children to 40 referred children. Correlation coefficients computed between two tests were strong, suggesting consistency in underlying global construct being measured; however, no compelling evidence supporting theoretical structure of two scales was…

Obtained Wherry hierarchical factor solution on Wechsler Adult Intelligence Scale-Revised subtests intercorrelations for 108 alcoholic adults. Found ability arrangement consistent with Vernon's structure-of-intellect model. Ability hierarchy consisted of strong general intelligence factor defined by all 11 subtests, which accounted for 49% of…

Articles responds to some issues raised in "The Bell Curve: Intelligence and Class Structure in American Life," such as the nature of intelligence, its measurement, the importance of personal decisions in determining life outcomes, and the modifiability of intelligence in infants and young children. (Author/JDM)

Stability of verbal reasoning test scores was measured for 146 students aged 8-13. Results suggest that reasoning test scores are not constant and vary considerably over time. Scores are not finite measures of intellectual capacity but of current verbal functioning, reflecting education and experiences to that point. (SK)

Confirmatory factor analyses of the third edition of the Wechsler Intelligence Scale for Children (WISC-III) using the Canadian normative sample (n=1,100 children) were conducted to verify the four-factor model found in the U.S. normative sample. Results paralleled those of the U.S. sample and support use of the WISC-III factor indexes. (SLD)
