This study attempted to (1) determine whether stroke patients (n=20) can safely increase their walking speed above that of comfortable walking; (2) describe the relationship between comfortable and maximum safe walking speed; and (3) examine correlations between maximum and comfortable speeds and a functional walking score. Subjects were able to…

Discusses a study of differences in nonliteral language use among deaf women, women who could hear, and women who could hear and who used sign language. Subjects told stories orally and in sign to children of 4 and 10 years. Deaf mothers' nonliteral content was higher, whereas hearing mothers' stories were longer. (Author/GH)

In discussing pharmacologic control of hypertension in children and adolescents who participate in sports, the second of two articles emphasizes drugs with few side effects and that usually do not alter heart rate (e.g., long-lasting angiotensin-converting enzyme inhibitors or calcium channel blockers). Such drugs allow continued sports…

This study sought to identify patterns of impaired acoustic laryngeal reaction time as a function of response complexity parallel to metabolic measures of brain function. Findings indicated that the disruption in speech motor control for 16 adult male developmental stutterers was systematically related to metabolic asymmetry in left superior and…

Describes female alcoholism patterns, characteristics, and obstacles to treatment. Argues that the most effective treatment program for female alcoholics requires consideration of gender-related factors, such as relationship expectations and sexual abuse. Outlines a holistic, comprehensive care model, intended for the unique needs and concerns of…

A student project that investigated the relationship between resting heart beat frequency and body mass of adult dogs is described. The results are compared to those of other mammals and birds. The procedure and results are included. (KR)

Describes the development of educational computer software called scenario software that was designed to incorporate advances in cognitive, affective, and physiological research. Instructional methods are outlined; the need to change from didactic methods to discovery learning is explained; and scenario software design features are discussed. (24…

Investigates the effect of secondary school physical education on fitness load: the product of the mean heart rate above threshold (144 bpm) and the time duration of heart rate above that threshold. Highly and moderately skilled students achieved fitness load more frequently than their lower skilled colleagues. (GLR)

This paper on physiologic correlates of speech production in children and youth with hearing impairments focuses specifically on the production of phonemes and includes data on respiration for speech production, phonation, speech aerodynamics, articulation, and acoustic analyses of speech by hearing-impaired persons. (Author/DB)

Describes a classification system devised for exercise-associated collapse in endurance events based on casualties observed at six Twin Cities Marathons. Major diagnostic criteria are body temperature and mental status. Management protocol includes fluid and fuel replacement, temperature correction, and leg cramp treatment. (Author/SM)

There is a generation gap in physiology teaching. Speculates on the causes of this phenomenon and reviews the predominant attempts at correction in programs over time. (DDR)

Describes a virtual experiment designed to introduce students to the theory and application of the electrocardiogram (ECG) and the mean electrical axis (MEA). Students are asked to reduce and analyze data, calculate and plot the MEA, and answer questions in the inquiry-based, experimental activity. (Author/WRM)

Describes a laboratory experience for upper-level science students that provides a hands-on approach to understanding the basics of experimental physiology. Students design an experiment to determine the relative importance of dilution of plasma proteins in the overall renal excretory response following volume expansion with intravenous saline.…

This article reviews competing theories of semantic organization in the brain, including modular models, unitary models, and the matrix theory, and provides supporting and refuting evidence for each, incorporating examples from the imaging literature. The literature does provide some support for distinct neural substrates that process specific…

Analyzes students' understanding of biological phenomena via the ontological categories of processes and matter. Analysis is based on tenth-grade students' explanations of biological phenomena such as photosynthesis, energy resources, temperature regulation, and the interrelationships between living and nonliving things.
