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…

Though some unexpected sex differences were discovered, the two diagnostic categories were not found to be psychometrically distinct. Further, the results of a longitudinal analysis suggested that, while IQ scores remained relatively stable over time within a subset of the original sample, achievement scores definitely declined.

Analyzed WISC-R profiles along a three-factor approach for purposes of differential diagnosis. Profiles of 278 school-verified learning disabled children were compared to those of Educable Mentally Impaired (N=141), Emotionally Impaired (N=67), Otherwise Impaired (N=61), and Nonimpaired (N=294). Resulting data was not useful in differential…

Findings showed an almost even percentage of boys and girls, that more girls had fathers with doctorate degrees, that girls' arithmetic and spatial abilities were not significantly different from boys', that girls increased or decreased in IQ more than boys in high school, and that boys' IQs and grade point averages were significantly correlated…

Reports on the findings of a comparative study of mental abilities of Mexican and American children. Discusses age, sex, social class, and urban-rural differences, as well as cultural differences. (SS)

Asserts that it is irrational that the ideas of genetics should be used by some scientists to support the ideologies of racism and sexism. Whether the boundaries of women's "place in society" were erected with the "bricks of theology or the cement of genetic determinism," the intention is that the barriers shall remain strong.

Describes a new theory of multiple intelligences (MI) that identifies seven relatively independent forms of information processing that individuals exhibit in differing patterns. Describes the following MI-related educational research projects: (1) Arts PROPEL; (2) the Key School project; and (3) Project Spectrum. (FMW)

Elementary children (n=112) comprising average IQ, high IQ, dyslexic, and normal readers were administered measures of planning, attention-arousal, simultaneous and successive processing, phonemic segmentation, and nonverbal IQ. Cognitive tasks differentiating dyslexic from normal readers were the successive processing tasks and two tasks of…

A model of the sources of differences in the learning potentials of students is presented, including group differences in learning potentials between gifted and nongifted students; interindividual differences between gifted students; intraindividual differences within one gifted student; and independent and interactive contributions of…

Responds to "The Bell Curve" by arguing that IQ is merely a statistical fiction, an artificial construct not corresponding to any real entity. Discusses the "seductive statistical trap of factor analysis" as it relates to IQ tests, multiple intelligences, content and bias of IQ tests, lack of validity of IQ tests for individual…

This study of employment outcomes of 869 Illinois supported employees, primarily with mental retardation or mental illness, found that minority-status employees were younger, had higher intelligence quotients, and earned more wages per month than did nonminority supported employees. Few differences among minority subgroups (African American,…

Cognitive ability of nondiabetic children and early and late onset diabetic children was compared. Diabetic children scored in the normal range in intelligence and academic performance, but showed evidence of school difficulties and memory deficiencies. Children's perceived self-competence and parents' reports of children's functioning and…

Addresses the impact of the ideology of IQ testing on African Americans and Asians. Presents an overview and an analysis of scholarly treatises that illustrate that IQ testing continues to be one mechanism for maintaining racial prejudice and inequality in the United States. (JS)

A reanalysis of data from three previously published studies on whether creativity is content general or content specific suggest that, contrary to the results of recent research, a content-general factor may explain 40-50% of the variance in creativity checklist scores. Results are analyzed in light of other studies. (Author/CR)

Suggests the ways in which teachers can structure their classrooms, provide a range of challenging activities, and develop their observational skills identify the intellectual strengths of their students, particularly through the use of Gardner's Multiple Intelligences Theory as a framework for recognizing children's intellectual strengths.…
