Information processing was measured in terms of reaction time and movement time to stimulus displays which differed in amount of information transmitted. Only reaction time increased as a linear function of number of bits in the stimulus display. Both show individual differences which significantly correlated with intelligence. (Author/RD)

Assessed test bias on the Wechsler Intelligence Test for Children-Revised (WISC-R) and Bender-Gestalt. On the Bender, evidence of bias was infrequent and irregular. On the WISC-R, group differences were most discernible for age, sex, family structure, and race. Consistent patterns of bias were not apparent among comparison groups. (Author)

Analyzes preschoolers' scores on the Developmental Test of Visual Motor Integration (VMI), the Slosson Intelligence Test (SIT), and the ABC Inventory (ABCI). Separate ANOVAs reveal no race effect on the VMI. Race differences favoring Whites are found for SIT and ABCI. There were no effects for sex on any measure. (Author)

The value of the Structure of Intellect Learning Abilities Test for identifying gifted children and predicting teacher perception of them was investigated with 138 intermediate grade students. (DLS)

This article examines psychometric analysis regarding the viability and limits of IQ testing in the context of "The Bell Curve." It discusses eyeball analysis versus item analysis, mean differences, validity coefficients, general intelligence, and IQ and gifted education, and urges a search for intrapersonal and environmental catalysts…

Nonverbal IQs were greater than verbal IQs for children (ages 3-7) on the Stanford-Binet: IV (n=53). However, WISC-III verbal and nonverbal IQs were similar for older children, 6-15 years of age (n=63). Stanford-Binet: IV profiles were generally consistent for the low-IQ and high-IQ groups with high scores on visual matching tests. (Contains…

This study of 54 individuals with head injuries compares a commonly used measure of physical disability, the Barthel Index, with three measures designed to assess intellectual functioning, communication, behavior, and mobility. The results indicate support for using scales other than the Barthel Index when describing disability following traumatic…

Administered an intelligence test to blacks and whites in 2 studies involving 254 community college students and 2 more studies involving 115 community college students. Results show that differences in knowledge between blacks and whites for items on an intelligence test, the meanings of words, can be eliminated when equal opportunities for…

Investigated test-retest reliability of the Test of Nonverbal Intelligence (TONI). Administered Form A and Form B of the TONI on two occasions 3 weeks apart to 50 students randomly selected from first and second grades. Results showed high test-retest reliability; correlation coefficients were .89 (Form A) and .83 (Form B). Found high parallel…

Compared area scores from short-form version of Stanford-Binet Intelligence Test (Fourth) with those from long form for 33 gifted children. Found three of five mean difference contrasts were significantly different and correlation coefficients between corresponding area scores and Test Composite were statistically significant. Suggests that…

Discusses differential and information processing theories of intelligence and the problems of measuring intelligence. Considers the influence of sociocultural factors on the test performance of individuals and the procedures which have been suggested to reduce bias. (RJC)

Validity of the Cognitive Levels Test (CLT) was evaluated by correlating test scores of 48 gifted 10-year-olds with scores on the Stanford-Binet intelligence scale as preschoolers as well as with scores from the California Achievement Test. Results indicated high degrees of CLT validity in both measuring cognitive ability and predicting academic…

This paper discusses applications of intelligence tests in schools, considering Binet's original warnings that his tests were primarily useful for identifying students needing intervention and inappropriate for classifying normal students. American applications of Binet's work for ranking are seen as stages of shifting from remedial to custodial…

The study assessed the utility of different factor structures of the Wechsler Intelligence Scale for Children-Revised in differentiating Israeli male students (ages 6-16) with learning disability from children with emotional disturbance. Based on several comparisons the results indicated that only the modified A.S. Kaufman's factor structure…
