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…

Used behavioral genetic methods and environmental assessment techniques to assess maladaptive behavior in 6- to 11-year-old twin pairs. Found that genetic variation accounts for majority of variance in parent-reported child maladaptive behavior; in contrast, observational coding and global impressions of parent-twin interactive behavior suggest…

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…

Examined low interrater agreement by decomposing common and unique variance among parent, adolescent, and observer reports of parental warmth and negativity into genetic and environmental factors. Model-fitting analyses findings generally supported predictions for warmth and negativity at Family and Individual levels. At the Social level, genetic…

Considers assumptions underlying design of Bussell et al.'s Nonshared Environment in Adolescent Development study. Suggests that a source of the common environment specific to this study is the effect of an individual in mutual ratings of relationship with siblings, leading to a larger common-environment effect across variables than within…

The president of the Pioneer Fund, a nonprofit foundation that makes grants into studies of individual and racial differences, addresses some of the media attacks on the fund in the context of the nature-nurture controversy. (SLD)

The Belgian psycho-pedagogue Ovide Decroly (1871-1932) acquired worldwide renown as one of the pioneers of the New Education Fellowship. In the period between the First and the Second World War, this organization was the forum par excellence for new education in Europe. This article analyzes Decroly's writings in order to examine the…

This study examined 2 samples of adolescents and mothers using a child-based design (Nonshared Environment in Adolescent Development [NEAD] project, N = 395 families) and a parent-based design (Twin Moms [TM] project, N = 236 twin family pairs) to compare genetic and environmental influences on mothering. For both samples, the same measures of…

The instrumental relationship to nature and the realist epistemology that dominate the analysis of contemporary environmental issues have prompted me to develop an interest in a socialized conception of science in environmental education (EE) so as to throw into question a certain overappreciation of scientific expertise whenever the environment…

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.…

As an answer to a previous article written by David Frey on creativity, the author argues that creativity is not innate but learned. He admits the important role creativity plays in counseling, but maintains that creativity is very much a developmental process that is influenced by the environment. (Author/SE)

Evidence on the poorer spatial visualization ability in various Negro populations compared to the White populations and on the direction and magnitude of sex differences in spatial ability relative to other abilities suggests the genetic hypothesis that spatial ability is enhanced by a sex-linked recessive gene and that, since the 20-30 percent…
