The growing importance of genomics and bioinformatics methods and paradigms in biology has been accompanied by an explosion of new curricula and pedagogies. An important question to ask about these educational innovations is whether they are having a meaningful impact on students' knowledge, attitudes, or skills. Although assessments are…

Evidence that genetic factors play a significant role in susceptibility for autism is reviewed, especially: (1) chromosomal abnormalities associated with autism; (2) single gene disorders associated with autism; and (3) twin and family studies of autism. However, recent genetic studies have failed to locate any genes having a major effect on…

Examines the empirical evidence cited in favor of the operation of genetic factors in attention-deficit hyperactivity disorder and argues that the evidence does not support a role for genetic factors in the disorder. Discusses problems compromising family, twin, and adoption studies. (JPB)

This article reviews and critiques the research on possible genetic factors in stuttering. The failure to consider epidemiologic factors is thought to have biased previous research, but recent data provide evidence that spontaneous recovery and chronicity are influenced by genetic factors. Findings support previous conclusions about combined…

This article reviews sex studies of children of cousin marriages and three studies of children of incestuous matings. It is argued that these studies, taken as a whole, provide no substantial evidence for an inbreeding depression effect within the polygenic system commonly asserted to determine IQ. (Author/DB)

This article explores the gene-finding process for developmental speech disorders (DSDs), specifically disorders of articulation/phonology and stuttering. It reviews existing behavioral genetic studies of these phenotypes, discusses roadblocks that may impede the molecular study of DSDs, and reviews the findings of the small number of molecular…

Describes an ongoing project that is investigating the correlation between journal cost and citation ratings in the fields of political science and genetics. Previous studies that relate journal costs to other variables are reviewed; the conceptual framework is explained; limitations of the study are considered; and further research is suggested.…

Raymond Cattell's efforts to sort out the relationships of genetic or environmental patterns to personality factors have contributed to behavior genetics. Early writings on the projected decline of intelligence in Britain, studies using Multivariate Abstract Variance Analysis, and other miscellaneous studies on personality factors and mental…

Asserts that Herrnstein and Murray's "The Bell Curve" (1994) is an attempt to influence and control public discourse about public policy and inequality. It examines four of the book's flaws in classification, analyses, research, and its failure to recognize intelligence as having both genotypic and phenotypic manifestations. (GR)
