Reflects on G. Zivin's framework on the development of expressive behavior. Stresses the need to include noncognitive, as well as cognitive, affective activation in the framework, and the necessity for the adoption of an inclusive, synthesizing strategy at this stage of knowledge. (HOD)

Details some problematic features of G. Zivin's framework on the development of expressive behavior. (HOD)

This issue's special section on canalization of behavioral development is introduced. In the special section, an invited paper by Gilbert Gottlieb, adopts a systems approach that stresses the complex interaction of genes, behavior, and environment. Several comments on the Gottlieb paper are also included. (BC)

Evaluates the epigenetic landscape metaphor in light of behavioral development. Cites two common errors in integrated models of behavior and biology: (1) fixing behavior as structure, thereby robbing it of dynamics and plasticity; and (2) assuming that a single optimal trajectory applies to development of organisms or systems. (BC)

The purpose of this paper is to provide a formal three-step explication of a question that has been traditionally viewed as fundamental to developmental theory construction and explanation: Is behavioral development continous or discontinuous, or is it both? First, a preliminary structural definition of behavioral development involving a certain…

Notes that psychologists' interest in behavioral development concerns individual differences in behavior. Explores complexities of genetic and environmental determination of development, and of canalization. Intelligence is considered as an example of the canalization of human behavior. (BC)

Maintains that (1) research questions must address intra- and extraorganism contextual relations and must be multidisciplinary in scope; (2) research must be sensitive to contextual variability and individual differences; and (3) scholars must develop empirically generative models linking the development of human beings with changing contexts. (BC)

Developmental models currently used by child behavioral toxicologists and teratologists are inadequate to address current issues in these fields. Both child behavioral teratology and toxicology scientifically study the impact of exposure to toxic agents on behavior development: teratology focuses on prenatal exposure and postnatal behavior…

This paper presents a model workshop focused on sex-typed behavior and developmental psychology, which is designed to examine the major theories based on biology, socialization or a complex developmental process. The materials concentrate on the three main theoretical approaches underlying the development of sex-role behaviors, i.e.,…

Outlines a developmental model of antisocial behavior. Reviews research on the etiology and course of antisocial behavior from early childhood through adolescence. The route to chronic delinquency is marked by a reliable developmental sequence of experiences. Discusses implications for prevention and intervention. (Author/BJV)

This volume, a compilation of essays and state-of-the-art reviews, re-evaluates the progress and current practices in early childhood education. Topics include some of the issues, problems and implications of developmental theory applied to preschool education; historical antecedents for early education; malnutrition and behavioral development;…
