In this article, the authors discuss their belief in organizing curricula around sets of causal models in order to provide students with opportunities not only to learn about the subject matter of particular disciplines, but also about how scientific knowledge is generated and justified. They describe a nine-week genetics course for high school…

The aim of this literature review is to assess the current state of knowledge regarding differences and similarities between the inattentive (IA) and combined (C) subtypes of Attention-Deficit/Hyperactivity Disorder (ADHD) in order to detail challenges concerning further conceptualization, diagnostics, and treatment. The literature on ADHD-IA and…

Haemoglobin, Hb is the red, protein pigment in blood that transports oxygen round the body. Decreased quantity could lead to anaemia, and when the anaemic condition turns severe, blood transfusion becomes inevitable. However, the safety of human source has become questionable in recent times, and this has aroused the interest of scientists to…

Biological reactivity to psychological stressors comprises a complex, integrated system of central neural and peripheral neuroendocrine responses designed to prepare the organism for challenge or threat. Developmental experience plays a role, along with heritable variation, in calibrating the response dynamics of this system. This calibration…

While it is well known that reading is highly heritable, less has been understood about the bases of these genetic influences. In this paper, we review the research that we have been conducting in recent years to examine genetic and environmental influences on the particular reading processes specified in the "dual-route" cognitive model of…

Long-term memory formation is regulated by many distinct molecular mechanisms that control gene expression. An emerging model for effecting a stable, coordinated pattern of gene transcription involves epigenetic tagging through modifications of histones or DNA. In this study, we investigated the regulation of histone phosphorylation in the…

Using pharmacological techniques, it has been demonstrated that both consolidation and extinction of Pavlovian fear conditioning are dependent to some extent upon L-type voltage-gated calcium channels (LVGCCs). Although these studies have successfully implicated LVGCCs in Pavlovian fear conditioning, they do not provide information about the…

Transcriptional activation is a key process required for long-term memory formation. Recently, the transcriptional coactivator CREB-binding protein (CBP) was shown to be critical for hippocampus-dependent long-term memory and hippocampal synaptic plasticity. As a coactivator with intrinsic histone acetyltransferase activity, CBP interacts with…

Music, as language, is a universal human trait. Throughout human history and across all cultures, people have produced and enjoyed music. Despite its ubiquity, the musical capacity is rarely studied as a biological function. Music is typically viewed as a cultural invention. In this paper, the evidence bearing on the biological perspective of the…

A new research finding related to a less costly and more convenient treatment for Gaucher's disease, the most common lysosomal storage disorder and genetic disorder affecting Jewish people of Eastern European ancestry is reported. The reports suggest that chemical chaperons could partially correct the genetic defect responsible for most cases of…

Data from Terman's "Genetic Studies of Genius" (1925-1959) relating to sample size, mean IQ, and variance of IQ scores were analyzed in terms of their conformation to the theoretically projected statistics derived from a consideration of the normal curve. (Author/RC)

The author, a psychologist, concerned himself with the question of whether mental growth and decay are fixed in each of us by heredity, that is by our genes, or how far they are influenced by upbringing, education, and other factors in our environment. (Author/RK)

The basic differences between the sexes are, after all, genetic rather than social or cultural. Article investigated the implications of this fact for teachers and learners. (Editor/RK)

Ethical issues which surround the reproductive technologies being used to assist infertile couples include social impact, surrogacy, access to service and confidentiality. The use of reproductive technologies does not appear to cause harm, and often does a lot of good for the family and society. Surrogacy could be a valuable tool for the infertile…

Author focused on differences between whites and negroes in the United States and more generally on racial variation in man. (Author/RK)
