The major finding of this study is that there is a larger socioeconomic status or Negro-White difference on intelligence measures than on measures of rote learning and memory. The difference in the performance of Negro and White children increases with age. (EH)

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…

Trotman responds to two criticisms of her previous research (EJ 168 902) on racial differences in intelligence and achievement. She clarifies the conclusions criticized by Longstreth (TM 503 913) and criticizes the conclusions reached by Wolff (TM 503 914). (BH)

Three data sources, analyzed presently, failed to reveal a Sex by Race or Sex by Socioeconomic Status interaction. It was suggested that Sex by Race differences in income, education, and so on could be the result of racially related sex role expectations or cultural prejudice. (Author/MV)

Trotman (EJ 168 902) indicated that Black and White families of similar socioeconomic status differ widely in intellectual home environment, and suggested the nonutility of socioeconomic status as a control in racial comparisons of IQ. The validity of Trotman's conclusions is questioned, both for methodology and results. (Author/BH)

Children read sets of words under three conditions: with no pictures, with related pictures, and with unrelated pictures. Results indicated that words were read more slowly whenever pictures were present; that unrelated pictures produced more interference than related pictures; and that both effects were inversely related to reading ability.…

Developmental differences in reasoning ability and item processing demands are analyzed in a study of cognitive determinants of number analogy performance in two IQ levels of elementary school children and college students. The amount of solution-related information in working memory was the crucial processing demand. Process differentiations of…

Relationships between six home environment measures, achievement and intelligence tests were examined by stepwise multiple regression analyses for a sample of 60 eight-year old children. Home variables were most successful in predicting achievement test scores, less successful regarding culture-dependent intelligence test scores, and least…

Groups of 270 Black and 270 White children drawn from the national stratified random sample used in the standardization of the Wechsler Intelligence Scale for Children-Revised (WISC-R) were matched on age, sex, and WISC-R Full-Scale Intelligence Quotient to facilitate investigation of the patterns of specific cognitive abilities.

Three conditions for administering creativity tests by Torrance and by Wallach and Kogan were compared: (1) untimed, gamelike; (2) conventional testlike; and (3) administration of measures under testlike conditions on two adjacent days, using the second testing as the predictor. The conventional testlike condition seems optimal. (Author/CP)

Three measures of field dependence were used to determine whether: (1) Mexican American students are more field dependent than Anglo Americans; (2) intercorrelations between the tests are significant and comparable for both cultures; and (3) field dependence significantly affects academic performance. These assumptions were generally not…

The confluence model of cognitive development was tested on 7,060 children. Family size, sibling order within family sizes, and hypothesized age-dependent effects were tested. Findings indicated an inverse relationship between family size and the cognitive measures; age-dependent effects and other confluence variables were found to be…

Trotman's study (EJ 168 902) correlating child rearing in Black and White samples to children's achievement and intelligence is criticized. Trotman made several erroneous conclusions, and did not add important information about the nature nurture controversy as it applies to racial differences in intelligence. (Author/BH)
