Comparisons of the Wechsler Intelligence Scale-Revised and Wechsler Adult Intelligence Scale-Revised were made in a sample of male delinquents to determine whether they would show differences in the degree to which the P>V sign occurred on them. A larger split between mean Verbal and mean Performance IQ was found on the WISC-R than on the WAIS-R.…

Argues that despite aberrations, false starts, misapplications, and unfortunate crystallizations of methods and interpretations, the differential psychology of cognitive abilities is an important part of psychological knowledge about human beings. (Author/GC)

Results tend to agree with previous general population samples in not indicating any significant association between total IQ and season of birth. (Author/DB)

The Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and the Stanford-Binet Intelligence Scale-Fourth Edition (SB-IV), were administered to 20 gifted children and 20 non-gifted children to examine the extent of the difference in IQ scores obtained on the two tests. Results show that the SB-IV Composite Score was significantly…

D. K. Detterman and M. H. Daniel's recognition (1989) that intertest correlations for intelligence quotient (IQ) might not be uniform across the range of ability (and age) was anticipated by C. E. Spearman (1904). Detterman and Daniel appear to have rediscovered Spearman's suggested law of diminishing returns. (SLD)

Provides new confidence intervals for Wechsler Intelligence Scale for Children-Revised (WISC-R) to improve accuracy over existing tables. Includes alternative confidence interval tables for WISC-R quotients at extreme levels where current tables are least accurate. New tables center confidence intervals on estimated true intelligence quotient and…

This study investigated the possibility that the widely reported relationship between IQ and inspection time (IT) in children may derived from the involvement of aspects of attention. Results with 49 children aged 8 to 11 years show that IT is a significant predictor of Colored Progressive Matrices scores after age and attention measures are…

Examined age changes in intellectual ability in the range from 16 to 89 years through 2 studies that involved IQs on the Wechsler Adult Intelligence Scale III (WAIS-III). Results are interpreted in the context of the fluid-crystallized intelligence theory of J. Horn. Studies used WAIS-III standardization data for 2,450 adults and longitudinal data…

Measuring student intelligence has been problematic in the United States since standardized testing first began in the early 1900s. The omnipresence of standardized testing in student populations is illustrated by the most popular contemporary tests which are used by some scholars to advance the notion that intelligence differences between whites…

The present paper represents a plea for perspective; it will look in detail at the current criticisms of psychological tests in the light of potential developments in theory and practice. (Author)

Discusses how viewing intelligence as a learned skill and not a genetic gift may make the standard IQ test a thing of the pedagogical past. (GB/Editor)

The study examined the WISC-R (Wechsler Intelligence Scale for Children-Revised) profiles of 26 intellectually gifted students with respect to idiographic and normative variability in performance between scales and among subtests. Results indicated (even among highly homogeneous ability groups) significant variability in performance, reflecting…

The article introduces the special issue of the journal on the issue of intelligence testing as it applies to the identification of gifted students. (Author/CL)

The author argues that intelligence testing is an invaluable and irreplaceable tool for identifying gifted children and obtaining a measure of the urgency of their special educational needs. He also offers ideas for how parents of exceptionally gifted children can create an environment in which their children's gifts can flourish. (Author/CL)

This study is concerned with the determination of relationships between the 1960 Revised Stanford-Binet Intelligence Scale, the Lorge-Thorndike Intelligence Test, and the Iowa Tests of Basic Skills. The primary objective of the investigation was to determine the predictive validity of the 1960 Stanford-Binet over a period of eight years. (Author)
