Recent advances in molecular genetics and epigenetics are reviewed that have major implications for the bio-behavioral sciences and for understanding how organisms adapt to their environments at both phylogenetic and ontogenic levels. From a post-genomics perspective, the environment is as crucial as the DNA sequence for constructing the…

Following a brief consideration of the nature of "stress" as implied in the articles in this special section, the possible role of biological measurements in the study of behavioral development is examined. (PCB)

In order to understand the complex behavior of an individual, what that individual has learned must be understood. Unfortunately, behavior analysis and psychology in general have not studied the cumulative effects of the learning principles. However, there are concepts in behavior analysis that, although not well researched, address this area.…

Gilbert Gottlieb's formative role in establishing a science of experimental behavioral embryology is described. His experimental program on the development of species identification served as a model for developmental psychobiologists seeking alternatives to the nature-nurture dichotomies prevalent in the 20th century. Two of the major concepts…

This article reviews some recent technical progress in the social sciences and three frontier areas including evolutionary theory as related to sociobiology, the theory of human rational choice, and cognitive science. These areas offer explanations for broad areas of human behavior. (Author/SA)

Presents summaries and opposing views of six of B. F. Skinner's major tenets of behavioristic psychology. Relates conflicting positions on issues as environmental determination, problem solving techniques, cultural reinforcement, and mental processing. (ML)

This paper reviews the developing merger of behavior analytic and other environmental approaches to child behavior development, and identifies critical issues confronting this area of research and intervention, including a profusion of terms, a need for more precise descriptive and experimental analyses, and conceptual integration of findings of…

This case study describes a selective mute Mexican American boy, who, at initial referral, had never spoken to peers or teachers at school. Treatment procedures employed shaping and reinforcement of speech in therapy sessions. Sessions involved the psychologist alone, the classroom teacher and psychologist, the boy's best friend and the…

Discusses theories, research, and educational aspects relating to nutrition behavior, including psychosocial and cultural factors, nutrition knowledge, motivation in nutrition behavior, nutrition education and the public, education and situational factors, school nutrition education, evaluating nutrition education, and adoption and maintenance of…
