The modern history of biology shows how Darwin's selectionist theory has replaced instructionist theories in explaining the operations of living things: first with inheritance through the gene pool of the 1850s, and second with the replacement of a template theory of immune system function in the 1960s. Today scholars in several disciplines…

In the field of communication studies the preeminent forms of explanation of human behavior have been the social and psychological, but biological origins may be as important to understanding human communication as are social origins. Communication research suggests a biological basis for certain patterns of adult interaction. Although these…

In an attempt to accommodate each of two perspectives (nature versus nurture) in the formulation of a developmental framework, two complementary approaches to developmental theory are presented. First, consideration is given to what is now known about the developmental process in general (thought out in terms of the question "Where is the…

This document addresses the principles of field crop insect control through biological, mechanical, and chemical processes. Identification, life history, damage, pesticides, pesticide use and environmental considerations are presented for the major pests of corn, alfalfa, beans, small grains, sugar beets, and potatoes. Each section is accompanied…

Biological differences between the sexes in motor, sensory, and some intellectual abilities are reviewed. The skills that lead to early success in school draw on female talents; as a result, boys are often labeled hyperactive. Journal availability: Human Nature, Inc., Subscriptions Department, P.O. Box 10702, Des Moines, Iowa 50340; single copy…

Discusses the significance of sociobiology in seeking biological explanations for animal and human social behavior through fresh application of Darwin's theories of evolution and natural selection. A glossary of sociobiology terms is included. For journal availability, see SO 505 653. (Author/DB)

The exploratory study examined patterns of regional cerebral blood flow in a surface and a deep dyslexic during reading. Significant differences in gray matter blood flow were found between subjects and normal controls. Also differences existed between the surface and deep dyslexic in the distribution of cortical perfusion. (Author/DB)

This study evaluated the influence of biological and environmental variables on the differences between the throwing performance of 100 five-year-old girls and boys. Results are analyzed and discussed. (Author/MT)

The problem discussed are: (1) Infants seen with medical conditions that have associated psychosocial problems including child abuse. (2) Infants seen who have recovered from critical illnesses, but are "at risk" for later developmental disability. (3) Infants seen with normal variations of behavior that are misinterpreted by their parents or…

Discusses the detrimental effects of air pollution, and especially sulfur dioxide, on human health. Any relaxation of existing national air pollution standards because of the energy crisis could be costly in terms of the nation's health. (JR)

A comprehensive view of population conditions as a psychological problem includes three ways in which demography and psychology interact: the transformation of a basic biological need into social values and symbolic expression, the fitting of crucial life events into a comprehensive view of human lives, and the integration of the methodology of…
