Explored personality correlates of pain perception and tolerance in a nonmedical sample and setting. Results showed no significant correlations with personality measures and cold-pressor scores, but a significant relationship between pain tolerance and cognitive focus; those who focused on the experimental situation had much shorter tolerance…

The rhythmic patterning of man's biochemical, physiological, and psychological behavior and the temporal relationships among various functions are the province of chronobiology. Citing animal and human studies, the author documents the progress of this new science and poses complex questions that it may answer about human behavior. (Editor/SJL)

Frederic Leer's article "Running as an Adjunct to Psychotherapy" (January 1980 issue of this journal) is criticized by three authors. They focus on the psychological and social effects of running and its usefulness as a treatment for depressed adults. (LAB)

Considers three different topics in speech research from the viewpoint of the physiology of the speech production mechanism: laryngeal control for voicing distinctions, articulatory dynamics in normal and dysarthric cases, and central mechanism of skilled movements. Includes a summary of a discussion on speech production. (RL)

Describes the development of a physiology course combining elements of instructional technology, computer assisted testing, and independent study at a college of nursing. (RAO)

Successful techniques for reducing tension and anxiety in athletes are described. (JD)

Techniques for accurately measuring body composition to determine desirable body weights are described and cautionary remarks against possible misuse are offered. (JD)

The efficacy of blood doping (infusion of blood into an athlete's circulatory system) has not been established and merits further research. (JD)

Computer simulation was used to analyze techniques of performing the flip long jump. (MM)

This report details several simulated divinq experiments on the human. These are suitable for undergraduate or graduate laboratories in human or environmental physiology. The experiment demonstrates that a diving reflex is precipitated by both facial cooling and apnea. (Author/RE)

An Olympic-type event for people over the age of 55 is described. (JD)

The article explores the theory that the sense of hearing evolved to help an organism localize its position in space and perform aural analyses of that space and describes two major kinds of hearing loss--conductive and sensorineural. (PHR)

Elementary school children learn about good nutrition and physical fitness through a series of stories that form the basic structure of a health education curriculum. (JD)

A comparison is drawn between muscle use and timing in the skills of overarm throwing and of service in tennis. (JD)

A review of experiments which demonstrate the release of ATP from skeletal muscle, cardiac muscle, and active brain tissue. Effects of exogenously applied ATP to brain tissue are discussed in relation to whole body exercise. (Author/SA)
