Presents the Genomic Analogy Model for Educators (GAME) strategy for making concepts in genomics easily understandable for both students and the general population by using familiar objects and concepts associated with daily life. Uses web-based tutorials accompanied by laboratory exercises that are intended to be used by students studying…

Discusses opportunities and challenges for the field of evolutionary biology, particularly in areas related to molecular genetic technologies, the environment, biodiversity, and public education. (Author/KHR)

The cytogenetic survey of 67 individuals previously identified as having mental retardation and autistic behaviors revealed only 1.5 percent with the fragile X chromosome. The finding suggests that most persons with fragile X syndrome do not have autistic behaviors severe enough to be identified as a secondary psychiatric diagnosis. (Author/DB)

Case studies are presented of four children, age four to six, with severe phonological disorders, demonstrating three generations of family members with speech/language problems. An autosomal dominant mode, a multifactorial-polygenic model, and a sex-specific threshold model for expression are discussed. (Author/JDD)

Describes 10 science fiction stories for young readers whose contents address recent developments on the frontiers of scientific research, including genetic engineering, artificial intelligence, and robotics. The use of these materials to inform young readers about the issues and dangers involved in scientific developments is discussed. (CLB)

A fragile site on the X chromosome has been implicated in developmental disabilities among both males and females. Data are presented on the characteristics and treatment of fragile X syndrome patients that can assist the school psychologist in program planning and appropriate referral. (Author/TE)

Clinical histories and physical findings are presented for 2 sisters with Rett syndrome. The older sister, age 25, was typically affected, whereas the younger sister, 22 years old, was affected with a seizure disorder showing an unusually early onset. The paper discusses hypotheses in genetic causation of Rett syndrome. (JDD)

Examines Gregor Mendel's family background, schooling, and the brotherhood of his monastery life for insights into how Mendel was stimulated to engage in plant hybridization, his precursors, and why he was successful in his endeavors. (RT)

Psychiatric evaluation of 14 males (ages 3-27 years) with the fragile X syndrome found pervasive hyperactivity, impulsivity, and attentional deficits, and a significant degree of anxiety. However, diagnostic criteria for persistent pervasive developmental disorder and autism were not met. (Author/DB)

Analyzed genetic and environmental contributions to intellectual change in 258 adopted and 93 biological children of 3-14 years. The effect of genes and family environment was significant at the time of the first measurement, but only genes made an additional contribution between the first and the second. (RJC)

Criticizes the application of the statistical procedures of the population-genetic approach within evolutionary biology to the study of psychological development. Argues that the application of the statistical methods of population genetics--primarily the analysis of variance--to the causes of psychological development is bound to result in a…

Argues that Gottlieb rejects population sampling and statistical analyses of distributions as he proposes that his experimental brand of mechanistic science is the only legitimate approach to developmental research. Maintains that Gottlieb exaggerates developmental uncertainty, based on his own research with extreme environmental manipulations.…

Argues that a truly developmental behavior genetics will have to go beyond the traditional quantitative approach of population genetics in order to produce developmental explanatory content about differences and similarities in developmental outcomes. (MDM)

Describes a laboratory method to allow students to complete electrophoresis and staining of DNA samples within 1 45-minute classroom period. (MKR)

Data from 148 identical and 111 fraternal twin pairs in which at least 1 member had a reading disability were statistically analyzed. Results suggest that genetic and shared-environment influences both contribute to the observed covariance between reading and mathematical deficits. (Author/DB)
