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. (Author/WRM)

This study examined age and gender differences and similarities in stress responses to September 11th. Adolescents, young adults, and adults reported using a variety of strategies to cope with the terrorist attacks including acceptance, positive thinking, and emotional expression. In addition, involuntary stress responses such as physiological…

This article seeks to inform physical educators of a variety of teaching considerations when engaging a student with a cochlear implant in a physical education class. It provides the general physical educator with: (1) background information including statistics; (2) a general device description with safety precautions for the student with a…

Two groups of children with moderate bilateral sensorineural hearing loss were studied. Tests of reading and underpinning skills were administered. Comparisons were made with normally hearing children of the same age. While reading levels were found to be similar to their hearing peers, the phonological awareness and receptive vocabularies of the…

People with developmental disabilities sleep less and experience higher incidence of clinical sleep disorders than the general population. Exploring the neurophysiology linking sleep with daytime performance in patients with developmental disabilities is now possible using minimally sufficient sleep and sleep-sensitive behavioral assays. Although…

Deficits in temporal resolution and/or the precedence effect may underlie part of the speech understanding difficulties experienced by older listeners in degraded acoustic environments. In a previous investigation, R. Roberts and J. Lister (2004) identified a positive correlation between measures of temporal resolution and the precedence effect,…
