Lower class black and lower class white first-grade children learned an unorganized and an organized list of words to test Jensen's hypothesis of racial differences in mental abilities. Both groups of children performed significantly better on the organized list with comparable means for each list. Most of the predicted relationships were not…

The research results indicate that, although sex differences in mathematical abilities are not pronounced before high school, for some reason by the end of that period boys do better than girls in mathematical computation and problem solving. Environmental and biological explanations, intervention strategies and further research needs are…

A computer scan of ACT Assessment records identified 3,427 sets of twins. The Hardy-Weinberg rule was used to estimate the proportion of monozygotic twins in the sample. Matrices of genetic and environmental influences were produced. The heaviest loadings were clearly in the genetic matrix. (SJL)

This paper considers the role of intelligence in lifetime achievement, noting the importance not only of general cognitive ability but also abilities not measured by standardized intelligence tests. It urges educators of the gifted to utilize their knowledge of intelligence and talent development to challenge the one-dimensional conception of…

Critiques ideas expressed by Gould in "The Mismeasure of Man." Agrees with Gould that many scientists who studied human intelligence were racist, but disagrees that their work must therefore necessarily be dismissed. Disputes Gould's claim that factor analysts who study human intelligence have reified their factors and that factor…

Michael Levin argues that data from the study are consistent with a black/white IQ difference that is significantly genetic. Richard Lynn maintains that adoption by middle-class, white families has no effect on intelligence. Waldman, Weinberg, and Scarr respond to these criticisms and support the original conclusions.

This editorial provides an informal review of "The Bell Curve" (Herrnstein and Murray, 1994). The book, packaged as scientific writing, is an attack on affirmative action and on government attempts to foster egalitarianism. It is a political treatise that assumes that racial differences in intelligence are valid and genetic. (SLD)

Redefines "Jensenism" in terms of the personal qualities and beliefs that have made Jensen a researcher of note, including tackling controversial topics with empiricism. Illustrates these aspects of "Jensenism" by recounting personal experiences with Jensen and his research. (SLD)

In addition to establishing the relationship between reaction time (RT) and intelligence, Jensen has explored the role of intraindividual variability and its genetic basis. Jensen's theories blend facts from behavioral research on RT with neurological events. (Author/SLD)

A battery of "g" loaded mental ability tests was administered to 274 Bedouin children and adolescents, full and half siblings from 106 families. Results demonstrate internal validity for the tests in this cultural context and support the idea that shared family environment is a strong determinant of sibling similarity for children in the…

This brief article reviews the literature on the relative importance of genetic or environmental influences on intelligence. It concludes that: (1) giftedness has various expressions; (2) intelligence encompasses a wide range of human abilities; (3) both subjective and objective assessment techniques should be used; and (4) all ethnicities have…

According to Gordon and Bridglall, the ability to learn is more of a developed human capacity than a fixed aptitude with which one is born. They argue that the emergence of academic ability is associated with exposure to specialized cultures that privilege the attitudes, knowledge, and skills that schools reward. Children who are born to and…

"The Bell Curve: Intelligence and Class Structure in American Life" by Richard J. Herrnstein and Charles Murray (New York: Free Press, 1994) has become one of the most controversial books of recent years. The crux of the controversy, the relationship between race and intelligence, has touched a nerve in the African American community.…

Traces social, cultural, economic, and political history shaping intelligence testing with respect to an inheritable intelligence level to conclude that interpretation of IQ has always been in a social and political context. (DW)
