Physiology is an integral component of any medical curriculum. Traditionally, the learning of physiology has relied heavily on systems-based didactic lectures. In 2001, the Nelson R. Mandela School of Medicine (NRMSM; Durban, South Africa) embarked on a problem-based curriculum in which the learning of physiology was integrated with relevant…

Interdisciplinary research requires that experts from multiple disciplines work together to combine methods and ideas in an integrative fashion to generate new knowledge. In many respects, the field of kinesiology is ideally positioned to take advantage of its inherent multidisciplinary design. Because of the multidisciplinary structure of…

American functionalist psychology constituted an effort to model scientific psychology on the successes of English evolutionary theory. In part it was a response to the stagnation of Wundt's psychological research program, which had been grounded in German experimental physiology. In part it was an attempt to make psychology more appealing within…

Does anxiety lead to depression more for girls than for boys? This study prospectively examines gender differences in the relationship between anxiety and depressive symptoms in early adolescence. One hundred thirteen 11- to 14-year-old middle school students complete questionnaires assessing depressive symptoms and three dimensions of anxiety…

In a recent influential report by the National Research Council, the role of the laboratory was introduced as follows: "Science courses and the laboratories associated with them should cultivate the ability of students to think independently. They should provide students with exposure to realistic scientific questions and highlight those aspects…

Investigated the effects of carbohydrate substrate availability on ratings of perceived exertion (RPE) and hormonal regulation during a competitive marathon. Data on marathon runners randomly assigned to receive carbohydrate or placebo indicated that those who ingested carbohydrate rather than placebo beverages were able to run at a higher…

Study aim: To assess direct effects of warm-up consisting of static and dynamic stretching exercises on sprint results attained by students differing in sprint performance. Material and methods: A group of 24 male and 19 female physical education students, including 12 and 9 sprinters, respectively. They performed warm-ups consisting of dynamic…

Previous work has found that many young children show different patterns of production of the hormone cortisol, which is sensitive to stress and challenge, on days when they are at child care compared with days when they are at home. At home, preschool age children typically show a decreasing pattern of cortisol production across the day which is…

Meeting the audiological management needs of deaf children with learning disabilities is demanding. The study specifically focused on the age at which audiological certainty, the degree, configuration and type of hearing loss, was established in 20 individuals with severe learning disability. Audiological records relating to each individual were…

The highly addictive drug methamphetamine has been associated with impairments in social cognitions as evidenced by changes in users' behaviors. Physiological changes in brain structure and functioning, particularly in the frontal lobe, have also been identified. The authors propose a biopsychosocial approach to understanding the effects of…

Research has shown over the years that the self-perceptions of older adults about their health and well-being may be at least as important as objective data for predicting the course of their health over time. I review a series of studies that span 30 years in which I and my colleagues have asked older adults in the community about their…

Event-related potential is a kind of neuroimaging tool which can be used in the study of neurodevelopment. Two areas of atypical development, children diagnosed with autism and children experiencing early psychosocial neglect, have benefited from ERPs. The physiological basis of ERPs and the constraints on their applications are also discussed.

Recent studies have supported the intriguing hypothesis that highly reactive infants are most susceptible to the effect of parenting. This study replicates and extends an earlier study on 4-year-olds concerning higher susceptibility of more fearful children to the quality of their relationships with their mothers, as shown by their physiological…

Why has technology become prevalent in science education without fundamentally improving test scores or student attitudes? We claim that the core of the problem is "how" technology is being used. Technologies such as simulations are currently not used to their full potential. For instance, physiology simulations often follow textbooks by…
