Explores the role of biological causation in the development of behavioral outcomes. Genes and other biological structures constitute complex behavior, but the behavior of complex organisms cannot be derived from the biogenetic units of which it is composed. (SLD)

Critiques an environmentalist view of the effects of nature and nurture on behavior. Argues for an interactionist position in which nature and nurture are totally and inextricably involved in each and every organismic response. (MP)

Discusses new research directions in the study of emotions, including postulations that emotion is relational rather than intrapsychic; emotion and an individual's goals are closely related; emotion "expressions" are social signals, not merely outward signs of internal states; and the physiology of emotion can regulate and be regulated.…

This review notes that more behavioral recovery is often seen following damage to the nervous system than should be possible from the limited capability of the nervous system for regeneration and reorganization. The review offers a framework for reconciling the effectiveness of early childhood intervention strategies and the conclusions of…

This essay argues that humans are capable of a large number of affect states; a distinction should be made among acute emotions, chronic moods, and temperamental vulnerabilities to a particular emotion state; and research on human effects will profit from a return to, and reinterpretation of, Sigmund Freud's suggestion of unconscious affect…

Health educators may be expecting the public to accept too much personal responsibility for disease. Genetic, environmental, and other factors may be as important as health-promoting behavior in avoiding disease. If health educators overstate the role of personal responsibility for health, they may lose credibility with the public. (PP)

Maintains that the "getting into shape" hypothesis of explaining the inverted-U distribution of exercise play across age is likely incorrect. Argues that the biological study of human physical activity play, as recommended by Pellegrini and Smith (1998), will reveal whether physical activity play represents an example of…

This paper argues that the emerging discipline of sociobiology has the potential of doing what epistemologists, developmental psychologists, psychoanalysts, and ethologists have been unable to do: to provide a theory documenting our inherited dispositions as reflected in cultural evolution and personal development. Accordingly, the paper begins…

Considers the increase in research on adolescence, with attention to its transitional aspects during the adolescent period and as a bridge between childhood and adulthood. In addition, discusses the effort to examine interactional processes between parent and child and between environment and genes, with respect to the articles of this special…

Comments on the special theme issue examining the roles of socialization, biology, and culture as they affect adaptive and maladaptive developmental outcomes. Proposes a theory-guided research approach, based on four assumptive components of contemporary developmental theories: systematic change and relative plasticity; relationism and…

Introduces this special theme issue examining the roles of socialization, biology, and culture as they affect adaptive and maladaptive developmental outcomes. Problems of adolescence addressed include antisocial behavior, depressive symptoms, substance abuse, low achievement, and eating problems. Considers factors implicated in successful…
