In the wake of his death, it is a fair tribute to Gilbert Gottlieb to recognize him as a central figure in the creation of conditions that permitted the introduction of developmental thinking in developmental psychology. These included exposing the sterility of the nature-nurture debate and the adoption of a biological framework that conceives of…

This paper considers first the concepts of temperament and emotion and then describes some of the genetic and neurochemical correlates of varied temperamental biases and their contribution to emotions. This discussion is followed by a detailed description of the infant temperamental biases called high- and low-reactive to unfamiliarity and their…

The neurobiological study of swallowing and its dysfunction, defined as dysphagia, has evolved over two centuries beginning with electrical stimulation applied directly to the central nervous system, and then followed by systematic investigations that have used lesioning, transmagnetic stimulation, magnetoencephalography, and functional magnetic…

We describe a model of the human eye that incorporates a variable converging lens. The model can be easily constructed by students with low-cost materials. It shows in a comprehensible way the functionality of the eye's optical system. Images of near and far objects can be focused. Also, the defects of near and farsighted eyes can be demonstrated.

Although fatigue is a common experience for pregnant women and new mothers, few measures of fatigue have been validated for use with this population. To address this gap, the authors assessed psychometric properties of the Multidimensional Assessment of Fatigue (MAF) scale, which was used in 2 independent samples of pregnant women. Results…

Decades of research have documented in school-aged children a persistent difficulty apprehending an overarching biological concept that encompasses animate entities such as humans and nonhuman animals, as well as plants. This has led many researchers to conclude that young children have yet to integrate plants and animate entities into a concept…

In this essay, the authors describe human consciousness as an embodied experience that emerges from a complex relationship of the biological and the phenomenological. Following arguments made by Lodge (2002) and Donald (2001), they argue that one primary way that human beings develop self-awareness of their own minds is by becoming aware of other…

This article describes a project for the Biology of HIV/AIDS course for undergraduate biology majors. This project challenged science students to engage the community on two different levels. They first had to interact directly and personally with HIV/AIDS activists. The proposal then encouraged them to think about and describe ways of engaging a…

Cell biology and molecular imaging technologies have made enormous progress in basic research. However, the transfer of this knowledge to the pharmaceutical drug discovery process, or even therapeutic improvements for disorders such as neuronal diseases, is still in its infancy. This transfer needs scientists who can integrate basic research with…

We describe an exercise, the production of a species action plan, which utilises components of both transmission mode and experiential learning. This exercise brings together students and a professional role model to promote a stronger engagement with aspects of local biodiversity management. We outline perceived benefits and outcomes of the…

In this study, the authors analyzed how students' grades in high school biology courses are associated with their predicted and actual grades in college courses. The results of the study revealed a disconnect between high school and college biology courses. High school students are not well-served by high grades in high school courses that are not…

We have designed a laboratory curriculum using the green and red fluorescent proteins (GFP and RFP) to visualize the cloning, expression, chromatography purification, crystallization, and protease-cleavage experiments of protein science. The EGFP and DsRed monomer (mDsRed)-coding sequences were amplified by PCR and cloned into pMAL (MBP-EGFP) or…

This study provided empirical support for tutor-led study groups using a physiological measurement and study survey data. The scope of this preliminary study included determining differences in biology and chemistry study group members' (N = 25) regarding learning styles and pulse rate changes. As hypothesized, there was significant evidence that…

Students often have great difficulties with applications of the energy principle, especially those from biology, although most introductory physics texts include a brief discussion of metabolism. We point out that many of these discussions are unsatisfactory, since they often fail to mention how biological systems are "thermal systems in…

A number of institutions have been, or are in the process of, modifying their biochemistry major to include some emphasis on the quantitative physical chemistry of biomolecules. Sometimes this is done as a replacement for part for the entire physical chemistry requirement, while at other institutions this is incorporated as a component into the…
