Discusses limitations of using behavioral genetic methods for understanding the environmental effects of poverty. Multiple methods provide strong evidence that poverty and related experiences influence children's development through environmental processes that go beyond genetically transmitted attributes. Socioeconomic status is a function of…

This article discusses the role of health educators and the principles which should guide their practice. Health educators are advised to remain vigilant in not misinterpreting research data. (IAH)

Data from 236 pairs of black twins and white twins aged 13-17 years were used to examine genetic and environmental factors influencing cranial size, an indirect estimate of brain volume. Genetic factors are required to account for the phenotypic variance in cranial capacity. (SLD)

Maintains that "Individual Development and Evolution: The Genesis of Novel Behavior" (Gilbert Gottlieb) is one of the most creative, integrative, and important works in the field of developmental comparative science. Gottlieb's work has provided scientific basis for the concept that developmental systems, and not genetic reductionism, is the only…

Contends that communication apprehension represents individuals' expression of inborn, biological functioning, antecedent to social experience and therefore independent of social learning processes. Presents a temperament-based conceptualization of communication apprehension; integrates neurologically-based temperament functions into three…

Attempts to show how genes and environments cooperate in the construction of organisms, focusing on how genes require environmental and behavioral inputs to function appropriately during the normal course of human development. The discussion is related to a model of probabilistic epigenesis. (SLD)

The biometrical school of scientists who fit models to IQ data traces their intellectual ancestry to R. Fisher (1918), but their genetic models have no predictive value. Fisher himself was critical of the concept of heritability, because assortative mating, such as for IQ, introduces complexities into the study of a genetic trait. (SLD)

Reviews "Rethinking Innateness: A Connectionist Perspective on Development" by Elman and others (1996). Maintains that the authors argue forcefully that the nature-nurture conflict is a false dichotomy and that they present convincing existence on the possibility of qualitative change. Argues that the authors do not succeed in proposing…

Discussion of the nature/nurture controversy in giftedness concludes that giftedness has a strong hereditary basis that is greatly influenced by educational experiences. The importance of the affective domain is also stressed. Some specific suggestions are offered to help students nurture themselves and to help parents and teachers nurture others.…

Examined relative contributions of genetic and environmental influences to the covariation between sibling relationships and mother/adolescent relationships in 719 same-sex sibling pairs of varying degrees of genetic relatedness. Found that the overlapping effects of shared environment on the two relationship subsystems explained most of the…

The introduction to this special issue on nature-nurture interactions notes that the following articles represent five biologically oriented research approaches which each provide a tutorial on the investigator's major research tool, a summary of current research understandings regarding language and learning differences, and a discussion of…

The genetic and environmental contributions to the development of general cognitive ability throughout the first 16 years of life were examined using sibling data from the Colorado Adoption Project. Correlations were analyzed along with structural equation models to characterize the genetic and environmental influences on longitudinal stability…

Matt Ridley, an Oxford-trained zoologist and science writer whose latest book is "Nature via Nurture: Genes, Experience, and What Makes Us Human" (2003a), wrote such an impressively clear and fascinating piece on "What Makes You Who You Are" that the author decided to use it to introduce the continuing pursuit of "What do I do to best promote…

This report presents data on 9-month-old twin pairs (n[MZ]=172; n[DZ]=333) from the Early Childhood Longitudinal Study, demonstrating that the role of genetic variation among infants is trivial and the shared and nonshared environment is substantial in accounting for the observed quality of infant-caregiver relationships. In contrast, maternal…

In the latter part of last year a Macquarie University academic aroused outrage with his comments over the supposed links between race and criminality. For his colleagues and the union alike, the case provided a difficult example of the clash of shared academic values and the right to speak. Here four participants in the controversy-- from NTEU's…
