This study used structural equation modeling to examine the effect of Stratum III (i.e., general intelligence) and Stratum II (i.e., Comprehension-Knowledge, Fluid Reasoning, Short-Term Memory, Processing Speed, and Visual Processing) factors of the Cattell-Horn-Carroll (CHC) cognitive abilities, as operationalized by the Wechsler Intelligence…

The factor structure of the Reynolds Intellectual Assessment Scales (RIAS; [Reynolds, C.R., & Kamphaus, R.W. (2003). "Reynolds Intellectual Assessment Scales". Lutz, FL: Psychological Assessment Resources, Inc.]) was investigated with a large (N=1163) independent sample of referred students (ages 6-18). More rigorous factor extraction criteria…

Describes a method that uses age equivalents and standard scores to recreate the full range of variability in the scores of low-functioning individuals. The method allows for a more complete interpretation of performance that can lead to better educational and therapeutic programming. (Author/MCF)

Comparisons between Vane's standardization sample and the Puerto Rican group yielded no significant differences in full scale scores. On the Vocabulary subtest, Puerto Rican subjects earned lower mean scores; on the non-verbal subtests, they scored higher than the normative group. (Author)

Discusses the relevance of the triarchic theory of human intelligence for the understanding of intelligence in multicultural populations. Argues that intelligence can mean different things to different cultural groups. Discusses recent research that moves toward the construction of broader-based measures of intelligence. Suggests that it is time…

Using 72 lower class children, concurrent validity of the WPPSI was studied using the Stanford-Binet as the criterion. Correlations between SB and WPPSI were moderately high. Among the WPPSI subtests, Vocabulary was significantly lower than all other subtests. The only significant sexual difference favored females on Similarities. (Author)

A total of 72 school psychologists administered both the WISC and WISC-R to 164 black, white and Latino children. These children had been referred to the school psychologist because of concerns about their intellectual ability. Significant WISC/WISC-R differences were found, with the WISC-R yielding lower results. (Author)

Examined relationships among planning, attention, simultaneous, and successive (PASS) cognitive processing tasks for a sample of hearing-impaired students. Results demonstrated that the PASS model was supported for the sample of 96 students, age 8 to 16. Bolsters other exploratory factorial studies which have shown PASS tasks to be consistent with…

Investigates the general factor and uniqueness characteristics of the individual tests of the Woodcock-Johnson Test of Cognitive Ability-Revised (WJTCA-R). Only 2 of the 19 WJTCA-R tests examined had low general factor loadings, while 2 had low uniqueness. All other tests had medium or high uniqueness. Discusses implications for clinical…

Examines the performance characteristics of 83 school-identified learning-disabled children on the Differential Ability Scales. Sixty percent showed a significant standard score discrepancy between the General Conceptual Ability and at least one achievement test. Implications regarding the educational diagnostic and intervention processes…

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…

Assesses the complementary ability of childhood intelligence and learning-related behavior to explain variation in achievement outcomes. Results reveal substantial proportions of assigned grade variance explained primarily by learning behavior and achievement test score explained by intelligence. Implications for educational assessment and…

The frequencies of consistent, mixed, and inconsistent lateral preference patterns in 648 elementary school age children were examined. No differences were found in IQ, reading, arithmetic, or spelling achievement scores among the three groups of children, at any age or for either sex. (Author)

Investigated the factor structure of a battery of tasks hypothesized to measure the constructs of the planning, attention, and simultaneous-successive (PASS) process model of human cognition. Results suggest that the original PASS model provides an improper factor solution. Recommends further refinement of the PASS theory or tests. (RJM)

Research concerned with the analysis and correlates of mathematical abilities, conducted primarily during the past decade, is reviewed. It is concluded that certain specific abilities, in addition to general intelligence, affect performance in mathematics. (Author)
