It appears that contingent reinforcement may have an effect upon the intelligence test performance of black adults as evidenced by the consistent trend of the IQ scores in the direction of the proposed hypothesis. However, the primary analysis of the data revealed no statistically significant differences among treatment groups. (Author)

Author concludes that "...intelligence is a power rather than an activity or a thing,...accident rather than substance, potency rather than act, and...many confusions relating to (its) character, measurement, development and function stem chiefly from the difficulties of putting it in the category of a power." (Auth.)

The effect of test content and context on the anxiety-intelligence relationship was investigated in a group-administration of an intelligence measure presumably free of anxiety-provoking cues, comprehension of cartoons and several conventional intelligence and achievement measures. Subjects were 177 boys and girls in grades 4 to 6. (MS)

Results indicated two broad factors of intelligence, interpreted as fluid intelligence and crystallized intelligence, coordinated with two broad factors of short-term learning, interpreted as indicating primary memory and secondary acquisition. (Author/RC)

Results from 1,297 adolescents and adults show that, consistent with hypothesized relationships, people classified as Intuitive by the MBTI earned higher KAIT Composite IQs than those classified as Sensing. However, most other hypotheses were not supported, as the Fluid-Crystallized discrepancy was not meaningfully related to any MBTI dimension.…

Growth curve analysis is applied to modeling test performance changes demonstrated by older adults following cognitive training or based on repeatedly presented fluid intelligence measures. Findings using data from a study by P. Bates and others (1986) provide evidence of plasticity in the fluid intelligence of older adults. (SLD)

Analyzes whether the latest version of the Wechsler Intelligence Scale for Children (WISC-III) measures the same constructs across its 11 age spans and what constructs are measured by the WISC-III. Findings indicate that WISC-III does measure the same constructs across ages but does not measure Freedom from Distractibility. (RJM)

Whether results previously found in adults, demonstrating a relationship between intellectual ability, speed of information processing, and memory capacity could be found in young children was studied with 109 children. Findings suggest that children's intelligence cannot be explained using a model of adult intelligence. (SLD)

A. S. Kaufman (1994) recommended that clinicians substitute Symbol Search, a new subtest, for the Coding subtest when calculating Performance and Full Scale IQs on the Wechsler Intelligence Scale for Children-III. Tables are provided for accurate derivation of IQs, percentile ranks, and confidence intervals when this substitution is made. (SLD)

As an alternative to equally weighted difference scores, examined an orthogonal reliable component analysis (RCA) solution and an oblique principal components analysis (PCA) solution for the standardization sample of the Kaufman Assessment Battery for Children (KABC; A. Kaufman and N. Kaufman, 1983). Discusses the practical implications of the…

Related inspection time (IT) to intelligence using a measure that has nonconfounded factors of mental ability to determine whether the association is based on fluid IQ or perceptual processes. Results for 37 undergraduates suggest that IT is related only to fluid intelligence, supporting the notion that IT reflects some fundamental underlying…

The study evaluated speed as a factor in Wechsler Intelligence Scale for Children-Revised performance with 66 high scoring and 36 average scoring children (ages 3-15 years). Results cast doubt on the utility of speed bonuses in tests of general intelligence with gifted children. (Author/DB)

Evaluated relation of performance on the Stanford-Binet Intelligence Scale: Fourth Edition to performance on the Wide Range Achievement Test-Revised and Woodcock-Johnson Psychoeducational Battery: Tests of Achievement for 31 normal, elementary-aged students using both the area score and Sattler's factor score approaches. (Author/ABL)

Compared Wechsler Intelligence Scale for Children-Revised (WISC-R) and Stanford-Binet Intelligence Scale-Fourth Edition (SB:FE) in identification and assessment of 48 intellectually gifted students. Findings suggest that scores of SB:FE and WISC-R, while both measuring 'g' factor, produce varying scores for gifted; many children currently in…

Discusses the changes in psychological testing and the rapidity of their development. Describes trends in the role of the test user, technical methodology of test construction, and interpretation of test scores. (Author)
