Outlined in this publication is a basic laboratory exercise which characterizes tubular secretion, using an isolated renal tubule preparation from teleost fish. Background information is given showing how these tubules of teleost fish, particularly marine teleosts, correspond to the proximal tubule of mammalian kidney. Materials needed, including…

This paper describes a number of factors which go into determining weight. The paper describes what calories are, how caloric expenditure is measured, and why caloric expenditure is different for different people. The paper then outlines the way the body tends to adjust food intake and exercise to maintain a constant body weight. It is speculated…

Part I, What Is Aging? examines various aspects of aging, some of its major characteristics, and what it is like to grow old in the U.S. today.…

Intended to help human communications in the wide area which is being opened up by computers and by the new thinking they have generated, this encyclopaedia has been compiled with the help of specialists who are physicists, mathematicians, computer scientists, systems consultants, economists, psychologists, physiologists, documentalists, and…

The first phase of this study sought to determine: (1) the effects of exercise intensity when total work loads were similar; (2) the effects of duration when intensities were controlled; and (3) a possible intensity duration interaction. Subjects were 36 male college students. Frequency of exercise was similar for all subjects. The initial level…

Research on early development is moving apace. Developmental psychology is again giving serious attention to ages and stages. This attention is due, in great part, to the formulations about cognitive development by Piaget. Earlier in the century, the experimental approach to child study came to reflect psychology's generally heavy commitment to…

In a study to learn whether or not poor nutrition, as indicated by low hemoglobin levels, affects intelligence and behavior, 113 Head Start children in Missoula, Montana took part.

To determine if a relationship exists between temporal patterns of hearing and temporal patterns of speech, and between personality and temporal patterns of speech and hearing, normally hearing subjects were measured on the following: Critical Fusion Frequency, tone burst durations, fusion over silent intervals, interrupted speech, interrupted…

The fundamental physical concepts needed in any appreciation of acoustical problems are discussed by a scientist and an architect. The major areas of interest are--(1) the nature of sound, (2) the behavior of sound in rooms, (3) the design of rooms for speech, (4) the design of rooms for music, (5) the design of studios, (6) the design of high…

The author reviews the literature and makes tentative conclusions concerning the physiological correlates of learning and memory. Particular attention is given to the issues of spinal cord learning, subcortical learning, cerebral cortex learning, localization of learning within the brain (specificity vs. non-specificity), and association areas…

This monograph on the anatomical and physiological aspects of the speech mechanism stresses the importance of a general understanding of the process of verbal communication. Contents include "Positions of the Body,""Basic Concepts Linked with the Speech Mechanism,""The Nervous System,""The Respiratory System--Sound-Power Source,""The…

A vocal register is a series or range of consecutive frequencies that can be produced with nearly identical voice quality. On the basis of research three fundamental registers can be defined and described: pulse, a low range of phonation; modal, a middle or "normal" range; and loft, a high range, described by some as falsetto. These…

This booklet, one in a series entitled "What Research Says to the Teacher," deals with physical fitness. The initial section discusses what physical fitness is and what its characteristics are. Section two details various aspects of physical fitness and its relation to mental health. The remainder of the document discusses briefly the need for…
