Girls and boys might differ in autistic symptoms and associated cognitive difficulties such as executive function (EF). We investigated sex differences in the relationship between parent rated EF and autistic symptoms in 116 children and adolescents (25 girls) aged 5-19 years with an intelligence quotient above 70 and an autism spectrum disorder…

Individuals with ASD often display externalizing behaviors, which have been associated with lower quality of life in adulthood. Social difficulties have been hypothesized to underlie externalizing problems among individuals with ASD (Klin and Volkmar in "Asperger Syndrome," 340-366, 2000), but this has never been tested empirically. We…

Serious identification of the gifted started with the work of Lewis Terman early in the 20th century. Terman's model, based largely on IQ, may have made sense in the early 20th century, but it no longer makes sense today. The problems that society needs its gifted individuals to solve in the 21st century require much more than IQ--in addition to…

This commentary is focused on Robert Sternberg's new Active Concerned Citizenship and Ethical Leadership (ACCEL) model. The new model is well conceived and goes far beyond existing models. It is especially attractive in that the emphasis is on ethics. Now more than ever before there is a clear need for education to support ethical reasoning and…

A controversial hypothesis [Charlton (2009). "Clever sillies: Why high-IQ people tend to be deficient in common sense." "Medical Hypotheses," 73, 867-870] has recently been proposed to account for why individuals of high-IQ and high social status tend to hold counter-intuitive views on social phenomena. It is claimed that these "clever sillies"…

This paper critically examines the portions of Arthur Jensen's books, "Genetics and Education" and "Educability and Group Differences," that concern Barbara Burks' 1928 study of adoptive families. Jensen cites the low correlations of children's IQs with measures of home environment from Burks' study as evidence that environment…

For 152 children, intelligence scores were assessed at 4 and 13 years of age, and the number of factors out of 10 social and family risk factors was counted. The presence of multiple risk factors in children's lives explained up to half the variance of children's IQ scores at 4 and 13 years. (MDM)

Criticizes and examines the motives behind Charles Murray's "The Bell Curve." Murray's book claimed that many social problems, including crime and poverty among blacks, could be explained by African Americans' lack of intelligence as evidenced by testing. Reveals the book's skewed methodology as well as its interest-guided financial…

This study extends findings on the effects of intensive applied behavior analytic treatment for children with autism who began treatment at a mean age of 5.5 years. The behavioral treatment group (n = 13, 8 boys) was compared to an eclectic treatment group (n = 12, 11 boys). Assignment to groups was made independently based on the availability of…

This article examines implicit social and political assumptions underlying "The Bell Curve." The book's suggestion that there is increasing stratification between the "IQ haves" and the "IQ have-nots" is critiqued, noting that the social construction of reality is obscured in the book's schema. Sociologists and gifted…

This commentary documents errors in the statistical analyses and interpretation of empirical evidence in "The Bell Curve" by R. Herrnstein and C. Murray (1994). "The Bell Curve" neglects the role of education and grossly overstates the case for IQ as a determinant of social success. (SLD)

Uses the book, "The Bell Curve," to illustrate the problem of "dangerous knowledge" and its power to harm. The article examines what the book is saying about intelligence, its meaning to society, and the book's possible effect on radicalizing political thought. (GR)

"The Bell Curve" by Richard J. Herrnstein and Charles A. Murray has ignited a fierce academic debate. They assert that IQ as measured by tests has replaced family wealth and status in determining jobs, income, class, and place in American life; that whites average 15 IQ points higher than blacks; and that high-IQ ruling elites, with…

"The Bell Curve" by Richard Herrnstein and Charles E. Murray has created a great deal of controversy because of its assertion that the key to explaining inequality and social problems in the United States is stratification by a unitary entity called intelligence, or cognitive ability, as measured by the intelligence quotient (IQ). Their…

Claims that the Carolina Abecedarian Project, an early intervention with children from economically and socially impoverished homes, has produced and maintained higher IQs in children at risk of mental retardation are examined for approximately 112 children. Assertions of project success are reviewed, and the implications are discussed. (SLD)
