The cerebral laterality of children with various configurations of verbal-performance discrepancies was inferred with an objective measure of lateral preference using Verbal and Performance IQ scores of the WISC-R. Results were interpreted as lending support to the notion of competition antagonism between cortical hemispheres and a possible…

The study compared the performance of 35 lower SES black kindergarten children on the WPPSI and the 1972 Norm Edition of the Stanford-Binet. Contrary to the findings of previous investigations before the restandardization of the Binet, the WPPSI was found to yield a significantly higher mean IQ than the Binet. (Author)

WISC-III IQs and subtest scaled scores of 440 students with specific learning disabilities were examined for gender differences. Boys exhibited statistically higher Full Scale, Verbal, and Performance IQs than did girls, as well as higher scores on six of seven subtests. Girls outperformed boys only on the Coding subtest.

Evaluated five intelligence test instruments for use with Malaysian children: Raven's Sijil Pelajaran Malaysia (SPM), WISC-R, School Failure Tolerance (SFT), Scale for Rating Behavior Characteristics of Superior Students (SRBCSS), and Parent Checklists. Found that Raven's SPM was an effective screening test, and the WISC-R the best measure to…

R. Herrnstein and C. Murray, in "The Bell Curve," stated six propositions concerning a "g" factor of intelligence. These propositions are found to be reasonably well supported in the scientific literature. These conclusions can be reached whether or not one accepts Herrnstein and Murray's claims about the social significance of…

Shows why the role of intelligence in everyday life is often underestimated, drawing an analogy that examines outcomes of life as analogs of items within classical test theory. In addition, a population-IQ model is explained that tests for the pooled effects of intelligence at individual, individual context, and population levels. (SLD)

Twenty-four gifted children with learning disabilities and a control group of nondisabled gifted children were administered the Wechsler Intelligence Scale for Children-Revised. The 8- to 12-year-old subjects were found to be more reliant on verbal conceptualization and reasoning than controls and demonstrated deficiencies in short-term auditory…

Comparisons were made of intelligence and developmental quotients for young autistic children (n=216) at initial assessment and reassessment at least two years later. Five-year follow-up data were then gathered to evaluate the relationship between stability of scores and age at initial assessment, severity of delay, and type of test. (Author/PB)

Fourteen teenage or young adult males disabled in print acquisition were studied to determine their patterns of verbal and spatial processing. It was found that, at retest a mean of 5.4 years later, the Similarities score significantly increased while the Vocabulary scores and Acquired Knowledge category actually decreased. (Author/DB)

Giftedness is a multi-dimensional phenomenon, and assessment should be concerned with the kinds of giftedness an individual exhibits. The Structure of Intellect (SOI) tests allow the identification of academic and creative giftedness. The SOI theory can also be used in partnership with brain research to provide a theory-based test of brain…

This article summarizes results of statistical analyses of an intelligence test for 155 braille-educated blind and low-vision children, aged 6-15, in the Netherlands. Results indicate some accuracy in predicting academic achievement; factor analysis indicates 4 interpretable factors in children with and without usable vision. (Author/PB)

When a battery of tests commonly associated with intelligence was administered to 144 13 year olds identified as extremely precocious, the verbally precocious students scored higher on verbal and general knowledge types of tests, and mathematically precocious students scored higher on tests of nonverbal reasoning, spatial ability, and memory.…

Responds to Dunn's paper on Hispanic-Anglo differences in IQ scores. Comments on Dunn's translation of Peabody Picture Vocabulary Test-Revised into Castilian Spanish, and concludes this version is inappropriate for mainland Puerto Rican and Mexican-American children due to improper translation and validation methods. Contains 27 references.…

Issues raised in responses to Linda Siegel's paper (EC221505) on the relationship between intelligence test scores and learning disabilities are addressed. Discussed are the nature of intelligence, classification of learning disabilities by discrepancy between intelligence test scores and achievement scores, the existence of learning disabilities,…

Bayesian and empirical Bayes approaches to shrinkage estimation of regression coefficients and uses of these in prediction (i.e., analyzing intelligence test data of children with learning problems) are investigated. The two methods are consistently better at predicting response variables than are either least squares or least absolute deviations.…
