Describes the "American Renaissance" Conference of 1998 at which 200 scholars from the extreme right gathered to discuss theories of racial differences. Focuses on some of the racial extremists, including one lecturer espousing fertility controls on nonwhites. (SLD)

Describes background literature associated with learning styles, the biological basis for learning styles and problems associated with using learning styles in education. Identifies four problems associated with learning styles research. Describes the results of a comparison of four learning styles instruments. (NH)

Virtual twins are unrelated siblings of the same age who are reared together from early infancy (UST-SA). Study uses a sample of 90 UST-SA pairs to comparatively assess the similarity of IQ subtest profile correlations for UST-SAs and twin pairs. Findings support explanatory models of intelligence that include genetic factors, demonstrating that…

Provides a general review and discussion of studies relating to hemispheric asymmetry in normal and reading disabled populations and possible implications with regard to the meaningfulness of IQ test results. Emphasizes research suggesting that the verbal factors of the WISC-III are related to the length of the left temporal bank of the planum…

Reviews recent research on the etiologies of autism, including genetic research, anatomic and neuroimaging studies, topics in neurophysiology research (including serotonin, dopamine, and opiods), immunologic research, studies of autism phenotype, and electroencephalographic studies. It concludes that, as of yet, research has found no clear…

A practical experiment on the PCR is described that has been used over several years as part of an undergraduate biochemistry and molecular biology course for chemistry students. In the first experimental session, students prepare their own DNA samples from epithelial cells of the mouth and use them as templates in the PCR. In the second session,…

Infertility affects many individuals and couples. This article begins with a case study of a couple who have experienced infertility yet do not identify infertility as their presenting problem. Clients and counselors alike often overlook infertility. This article offers an overview of the biology of infertility and its psychological and…

Objective: Although abnormalities of neural circuits involving the cortex, striatum, and thalamus are hypothesized to underlie Tourette's disorder, the neuronal abnormalities within components of these circuits are unknown. The purpose of this study was to examine the cellular neurochemistry within these circuits in Tourette's disorder using…

In two H[subscript 2] [superscript 15]O PET scan experiments, we investigated the cerebral correlates of explicit and implicit knowledge in a serial reaction time (SRT) task. To do so, we used a novel application of the Process Dissociation Procedure, a behavioral paradigm that makes it possible to separately assess conscious and unconscious…

The author describes his program of research over the past 25 years. This research falls into 6 areas that are interdependent and that inform each other. The overall program is guided by 3 bioecological principles that posit the need for proximal processes and motivation to actualize biological potential. The author presents examples of…

The emergence of minimally intrusive techniques for collecting biological data creates a case for the inclusion of these data into bullying research models. This integration would produce a more comprehensive understanding of the problems and better direct intervention and prevention techniques, which are currently based primarily on self-report,…

This paper focuses upon the developmental role of rough and tumble (R&T) play with particular attention to the narratives that children use to underpin such activities. A review of the literature suggests that current early years research and practice pays scant attention to children's outdoor free play activities. A piece of original research is…

This study examining children's understanding of biological inheritance addressed four central questions: (1) are young children able to distinguish between the relative influences of nature and nurture in their understanding of how physical characteristics versus behaviors and preferences develop in animals? (2) does children's understanding of…

This paper discusses factors that relate to the development of children's theory of mind. Cognitive and biosocial views of the development of theory of mind are distinquished. The paper maintains that all cultures recognize the intentional personhood of children in the first two years, though they vary in their methods of dealing with this…

A longitudinal study of mental development during the first 6 years of life was conducted to determine whether different social and biological variables were related to mental development at different ages. A total of 218 children having complete neonatal records of 12 biological variables were studied at 6-month intervals until the children were…
