Tested whether alpha power in different sub-bands is selectively related to intelligence. For 74 Austrian subjects, the EEG was recorded during a resting session and 2 different intelligence tests were performed. Findings show a strong positive correlation between intelligence and alpha power. (SLD)

Investigates long-term stability of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) for children with specific learning disability (SLD), serious emotional disability (SED), and mental retardation (MR). There were no differential effects of disability groups on long-term stability coefficients. Stability coefficients for Full…

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…

Studied the complementary nature of Illinois Test of Psycholingusitic Abilities (ITPA) and Wechsler Intelligence Scale for Children Revised (WISC-R) in a sample of 60 language-impaired children. Results suggest that the ITPA is more sensitive to differences in children's verbal and performance abilities than the WISC-R. (SLD)

Studied the factors underlying the aging effects seen on the Wechsler Intelligence Scale for Adults-Revised (WAIS-R) and the scale's third edition (WAIS-III) using the French standardization samples of 1,104 for the WAIS-III and 1,000 for the WAIS-R. Results show that the observed decline in scores for both tests cannot be fully explained with a…

The article reviews the development of infant cognitive assessment and describes selected tests. Considerations in choosing, administering, and interpreting the results of infant intelligence/cognitive assessment instruments are outlined. The usefulness of cognitive assessment is discussed as are new approaches to assessment. (Author/DB)

This study of 60 special education children found that Wechsler Intelligence Scale for Children-III (WISC-III) scores correlated significantly and positively with the Wide Range Achievement Test-3 (WRAT-3). Correlations between the two tests were much higher than those reported in test manuals. Mean WISC-III scores were consistently higher than…

Discusses Bauman's (1991) evaluation of stability of Wechsler Intelligence Scale for Children (Revised) IQs in children with learning difficulties. Argues that some procedures produced magnified estimates of instability. Presents reanalysis of data that suggests that, although stability coefficients were high, approximately 25 percent of sample…

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…

Examined student records of 130 children with learning difficulties who had been tested twice to determine the stability of Wechsler Intelligence Scale for Children-Revised (WISC-R) scores over time. Results suggest that the intelligence quotients in this population are not as stable as was previously thought, and this may provide rationale for…

Discusses intelligence tests in relation to theory of cognitive processing which can serve as model for reconceptualizing cognitive functioning. Analyzes what is measured using Wechsler, Kaufman Assessment Battery for Children, Stanford-Binet IV, and McCarthy scales, and reflects on effectiveness. Suggests that Planning, Attention, Simultaneous,…

Describes the developmental status of three categories of intelligence tests: psychometric abilities, neuropsychological models, and dynamic assessments, and applies them in the educational setting. Notes trends in basic and applied research, and their influence on the further evolution of intelligence testing. (MMU)

Wechsler Intelligence Scale for Children--Third Edition (D. Wechsler, 1991) (WISC-III) standardization data for 2200 children and WISC-III data for 33 brain-injured and 66 comparisons were used to explore premorbid prediction strategies for use with children. Results support the utility of approaches based on best WISC-III performance and on…

The long-term stability of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) (D. Wechsler, 1991) was studied with 667 children twice evaluated for special education consideration. Test-retest reliability coefficients are reported, providing the highest estimates of WISC-III stability yet reported. (SLD)
