Presents an activity in which students perform a classic experiment designed by two Nobel Laureates to study mutation and scientific reasoning. (ASK)

Describes a laboratory employed in undergraduate teaching that uses fruit flies to test student-selected compounds for their ability to cause mutations. Requires no prior experience with fruit flies, incorporates a student design component, and employs both rigorous controls and statistical analyses. (DDR)

Examined genetic and environmental contribution to self-reported peer-group characteristics among adoptive and nonadoptive adolescent sibling pairs. Found that although peer preference is influenced, in large part, by nonshared environment factors, genetic influence is present. Substantial genetic influence emerged for college orientation, and…

Describes how to use the World Wide Web to study the current progress of the Human Genome Project. Uses free-access DNA databases and other web sites that are user-friendly for students. (YDS)

Replies to C. M. Condit's responses to the authors' articles and comments advancing a communibiological paradigm. Argues that a general misidentification of the level of abstraction (paradigm not theory) drives Condit's complaints about communibiology, and outlines several misrepresentations of the authors' position. (SR)

Examines contemporary research on parental socialization. Highlights research designs that consider inherited, dispositional, and experiential factors in estimating influence. Describes evidence addressing issues of causality regarding the scope and nature of parental influences. Recommends basing conclusions about the significance of parenting on…

Suggests that music is a psychic necessity that originates in the structure of the brain and is passed on genetically from one generation to the next. States that both the differentiations by culture and subculture and the human fundamental impetus to make music should be a part of music education. (CMK)

This article reviews recent advances in the "new genetics" and shows how such advances affect special education. Focusing on Williams, Fragile X, Prader-Willi, and Down syndromes, it notes how etiology-related cognitive-linguistic profiles and propensities to distinct personalities and behavior problems point the way to specific,…

Reports on the administration and grading of automated tests in five successive semesters of a course in genetics and evolution. Students showed a gain in learning. Suggests that gains in learning will vary with discipline, teaching technique, and student background. (Author/MM)

Objective: To study the genetic and environmental contributions to stability and change of attention-deficit/hyperactivity disorder (ADHD) symptoms between 8 and 9 and 13 and 14 years of age. Method: The sample included 1,480 twin pairs born in Sweden between May 1985 and December 1986. At wave 1 in 1994, when twins were 8-9 years old, 1,106 (75%)…

Though many cognitive abilities exhibit marked decline over the adult years, individual differences in rates of change have been observed. In the current study, biometrical latent growth models were used to examine sources of variability for ability level (intercept) and change (linear and quadratic effects) for verbal, fluid, memory, and…

This project was designed to examine the feasibility of using a "collapsed day" to explore socio-scientific issues relating to genes and genetic engineering in secondary schools by enabling science and humanities staff to collaborate. It was believed that science staff would have expertise in promoting understanding of genetics and humanities…

Despite extensive research, questions underlying the nature and nurture of talent remain both numerous and diverse. In the current paper, we present an account that addresses 2 of the primary questions inspired by this debate: (a) the very existence of innate talents and (b) how exceptional abilities are developed. The development of exceptional…

"The Kallikak Family" is a pre-eminent text in the history of mental retardation and psychology in which Goddard (1912) claimed he proved the heritability of feeble-mindedness and the necessity of institutionalization. The book contains 14 photographs, some of which have been retouched. These photographs were interpreted in this paper within the…

In recent years, real-time polymerase chain reaction (PCR) has emerged as a robust and widely used methodology for biological investigation because it can detect and quantify very small amounts of specific nucleic acid sequences. As a research tool, a major application of this technology is the rapid and accurate assessment of changes in gene…
