Evidence is presented in support of psychometric "g," arguing that it accounts for most of the prediction of educational and vocational criteria that is possible from a battery of tests of cognitive tasks. Providing the best measure of "g" is explored. (SLD)

Describes exploratory and confirmatory analyses of verbal-performance procedures to illustrate concepts and procedures for analysis of correlated factors. Argues that, based on convergent and discriminant validity criteria, factors should have higher correlations with variables that they purport to measure than with other variables. Discusses…

Offers alternative analyses and interpretations of Macmann and Barnett's research data and results. Contends that intelligence is complex and that intelligence testing is important component of school psychological practice. Discusses relation and frequent inconsistency between research and practice. (CRR)

This study, involving 47 deaf and hard-of-hearing school-age children, found that the Wechsler Intelligence Scale for Children-Third Edition Performance scale was highly related to the WISC-Revised Performance scale and moderately related to the Wide Range Achievement Test-Revised subscales. Performance IQs of students who communicated orally or…

Tested one-, two-, three-, and four-factor models within normal and psychiatric adolescent inpatient groups to confirm the factor structure for the Wechsler Intelligence Scale for Children-Revised (WISC-R). For both samples, the Kaufman three-factor solution had the best overall fit of the WISC-R subtest covariance structure. Other models were…

Investigated joint factor structure of Differential Abilities Scale and Wechsler Intelligence Scale for Children-Revised for 115 children. Compared theoretically supportable models (Spearman's General factor; Wechsler's Verbal, Performance, and Freedom from Distractibility factors; Elliott's verbal, nonverbal, spatial, and diagnostic perspective)…

Of 75 elementary and middle school gifted students, 44 percent of students' Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) Composite scores and 28 percent of students' Wechsler Intelligence Scale for Children-Revised (WISC-R) Full Scale IQ scores were over 10 points different from their Test of Cognitive Skills (TCS) Cognitive Skills…

A factor analysis was conducted for a sample of 200 white and Hispanic children (ages 6-11) using the Wechsler Intelligence Scale for Children-Revised. Results indicated that the two-factor solution was similar for the two groups, but there were notable differences for the three-factor solution, relative measures of "g," and subtest…

Aspects of intellectual function were investigated in a school age sample of 17 Fragile X individuals, employing the Wechsler Intelligence Scale for Children (Revised). The general ability of the sample was substantially below normative average because of the significantly poorer performance by males than females. (Author/DB)

Thirty-five gifted elementary children were tested with the Wechsler Intelligence Scale for Children III (WISC-III) and results were compared to a previous administration of the WISC (Revised). Scores were significantly higher on all three WISC-R global scales and most subtest scaled scores. Correlation coefficients between the tests were…

To assess the effects of individual attentional focus differences on measures of mental skills, distractibility was studied for 272 first- and second-year college undergraduates through a speeded visual search task and tests of mental and verbal ability. Results suggest that perceptual/attentional factors are an important aspect of measured…

The relationship between speed of information processing (SIP) and psychometric intelligence was investigated by giving 60 college students (22 males and 38 females) 2 choice reaction time (RT) tests (modified Hick paradigm) and Raven's Advanced Progressive Matrices. Results support an association between intelligence and SIP. (SLD)

Data from standardization sample (n=1,700) of Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R) were used to develop table that gives Full Scale intelligence quotients (IQs) for four-subtest (Comprehension, Arithmetic, Picture Completion, Block Design) abbreviated form of scale. Reports reliability and validity coefficients…

Eight-seven adult outpatients in Edinburgh (Scotland) were tested with the Wechsler Adult Intelligence Scale--Revised (WAIS-R) and a test of visual inspection time (IT). Factor analysis confirms that IT correlates more strongly with performance than with verbal intelligence quotient (IQ) scores. Implications for the study of IT and mental tests…

Statistical analyses of scores on subtests of the Intelligence Test for Visually Impaired Children were done for two groups of children, either with or without usable vision. Results suggest that the battery has differential factorial and predictive validity. (Author/DB)
