Tympanic membrane (TM) temperature asymmetry has been proposed as a phenotypic marker of vulnerability to negative emotionality in children. Little is known about the stability of TM temperatures or how readily one can obtain a reliable index of the phenotype. TM temperatures were collected from 3- to 5-year-old children (N=73) over 5 months…

This study offers novel information to the acute exercise-feeling state literature, by using a community sample of exercisers participating in a 12-week exercise program to compare feeling state changes of those who exercised at a HISD versus a LILD. Within this study, pre- and post-exercise feelings states were compared between the two different…

The 2005 Claude Bernard Distinguished Lecture was presented at the XXXV International Congress of Physiological Sciences (IUPS) in San Diego, CA, by Ann J. Sefton. Dr. Sefton is an Emeritus Professor of Physiology of the University of Sydney and co-Chair of the IUPS Education Committee. A full profile of Dr. Sefton is included in this issue's "The…

Participating in some form of a warm-up prior to engaging in physical activity is considered an acceptable and valid practice. Nonetheless, the topic has been debated among those in the sport and physical education field for a number of years. Some professionals believe warm-up is essential to physical activity, while others believe warm-up is not…

A study of students of a traditional two-semester Anatomy and Physiology class was made to determine factors that contributed to success in the coursework. The test established a co-relation between the amount of study in mathematics and science done previously in school and final grades in the subject.

No previous studies compare the prevalence of physiological hearing loss among older adults by nonmetro/metro residence. Also, there is little information on their relative successes in accommodating hearing loss with a hearing aid. This study sought to bridge these gaps by analyzing the 8,222 respondents to Wave 1 (1993?1994) of the national…

We previously examined how three approaches to directing students in a laboratory setting impacted their ability to repair a faulty mental model in respiratory physiology (Modell, HI, Michael JA, Adamson T, Goldberg J, Horwitz BA, Bruce DS, Hudson ML, Whitescarver SA, and Williams S. Adv Physiol Educ 23: 82?90, 2000). This study addresses issues…

We investigated the impact of relative marital power on 72 newlywed couples' endocrinological responses to marital conflict. Marital power was determined by comparing spouse's reports of dependent love for one another. Less powerful spouses displayed elevated adreno-corticotropic hormone ACTH responses to a conflict discussion. Shared power…

Ubiquitous 1/f scaling in human cognition and physiology suggests a mind-body interaction that contradicts commonly held assumptions. The intrinsic dynamics of psychological phenomena are interaction dominant (rather than component dominant), and the origin of purposive behavior lies with a general principle of self-organization (rather than a…

The validity of videofluoroscopic swallowing assessments rests on the understanding that thin, nectar-, honey-, and spoon-thick radiopaque liquids resemble nonopaque liquids, both in their consistency and in the variations in swallowing that they elicit. Tongue movements during sequential swallows of opaque and nonopaque liquids were studied in 8…

In white matter disorders such as leukodystrophies (LD), periventricular leucomalacia (PVL), or multiple sclerosis (MS), the hypomyelination or the remyelination failure by oligodendrocyte progenitor cells involves errors in the sequence of events that normally occur during development when progenitors proliferate, migrate through the white…

Most children diagnosed today with acute lymphoblastic leukemia (ALL) will be cured. However, treatment entails risk of neurotoxicity, causing deficits in neurocognitive function that can persist in the years after treatment is completed. Many of the components of leukemia therapy can contribute to adverse neurologic sequelae, including…

The development of feeding and swallowing is the result of a complex interface between the developing nervous system, various physiological systems, and the environment. The purpose of this article is to review the neurobiology, development, and assessment of feeding and swallowing during early infancy. In recent years, there have been exciting…

Societal myths argue against active expression of sexuality in older adults, but these prejudices are unfounded. Using a deconstructionist framework, this article addresses issues surrounding sexuality in older adults. Implications for clinical practice are given.

The relationship between two classes of retrieval process--retrieval orientation and retrieval effort--was investigated using electrophysiological (ERP) and behavioural measures. ERPs were recorded during retrieval phases of exclusion tasks in which participants focused on retrieval of either phonological or semantic associates that were generated…
