Subjected the standardization data for the Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the original Wechsler Adult Intelligence Scale (WAIS) to principal-factor analysis. A two-factor solution was adopted for each scale. The stability of the two factors, Verbal Comprehension and Perceptual Organization, was high both within and between…

Compared scores on the Peabody Picture Vocabulary Test-Revised (PPVT-R) and Wechsler Intelligence Scale for Children-Revised (WISC-R) for 40 nonexceptional second graders. Subjects tended to score lower on PPVT-R than on WISC-R; scores from the tests were moderately correlated; and order of administration did not appear to alter scores. (NRB)

A single subtest score that might be out of pattern for a youngster means little if other subtest scores that correlate highly with the subtest in question are in pattern. (Author)

The relationship between nutritional status and intellectual capacity in 6-year-old children was investigated in 83 subjects of medium-high socio-economic status, without any apparent risk of malnutrition and normal or high intellectual capacity. Nutritional status was evaluated by measuring food consumption, anthropometrical measurements and…

Explored the relationships of the Revised Peabody Picture Vocabulary Test (PPVT-R), Peabody Individual Achievement Test, and the McCarthy Scales of Children's Abilities in elementary students. The PPVT-R appears to be most appropriate as a brief measure of verbal comprehension, rather than a substitute for the McCarthy scales. (JAC)

A verbal comprehension deviation quotient and a perceptual organization deviation quotient are presented as alternatives to the Verbal and Performance IQs when attempting to measure the Wechsler Intelligence Scale for Children-Revised verbal comprehension and perceptual organization factors. The freedom from distractibility deviation quotient…

Scores on Raven's Progressive Matrices correlated positively with electroencephalogram-recorded alpha rhythm frequency (AF) in 101 healthy male adults, as did one test of verbal ability and one of mental performance. However, AF did not show significant relationships with general intelligence or spatial and arithmetic abilities. (SLD)

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…

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…

Comparison of area and subtest scores on the Stanford Binet Intelligence Scale (Fourth Edition) for 15 autistic retarded children and 15 nonautistic retarded children found that the children with autism scored substantially lower in the verbal reasoning area and on the subtests of Comprehension and Absurdities than did the nonautistic children.…
