Defines life-span developmental psychology as the study of constancy and change in behavior throughout the life course. Advances metatheoretical view regarding development. Stresses focus on the dynamic and continuous interplay between growth (gain) and decline (loss). Examines structural contextual factors and study of range of plasticity in…

Describes growth in the number of studies of behavior development conducted in Japan during the last 20 years and identifies areas of development receiving attention by Japanese researchers. (RH)

Are there universal characteristics of adult thought? If so, how do they evolve and manifest themselves in cultures throughout the world? Piaget's formulation of formal operations is the best known and most extensively researched answer to the question regarding universal characteristics. Theoretical alternatives to formal operations differ in the…

In contrast to earlier notions, a systems view of an organism's development sees genes as only one component in a hierarchy of influences that produces finished traits and differentiation. Developmental canalization proceeds from genes, behavior, and environment as well as from the coaction of these factors. (BC)

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)

Addresses nutritional problems associated with developmental problems in infancy and childhood. Nutritional problems are often linked to environmental disadvantage; the possibility exists for long-term developmental effects. Treatment for undernutrition does not appear to reverse all negative effects. Prevention of nutritional disorders is better…

Reports on the misconceptions held about behavior analysis among students in two advanced undergraduate courses in behavior modification. Finds that only 3 of 13 common misconceptions were held widely. Reveals that these three misconceptions were resistant to change. (CFR)

Reviews research on the heritability of intellectual factors, personality factors, and psychopathology. Discusses the importance of investigating within-family environmental differences in order to understand the environmental origins of individual differences in development. (Author/BJV)

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)

Argues that an evolutionary perspective can unite the study of species-typical development and individual variation. Provides examples from the domains of personality, social, and intellectual development. Maintains that understanding the ways in which genes and environments work together helps developmentalists identify children who need…

In all of his published work, Jean Piaget never abandoned his original theoretical framework for the understanding of human development. This framework insists that intelligence is essentially a biological phenomenon; its development is best understood as the development of a sophisticated and highly successful adaptation device. This device…

Constructs a model applying evolutionary biology theory to the development of children's sense of justice. Maintains that competition for scarce resources causes many of the moral problems involving justice. Examines the place of emotions in the sense of justice. Hypothesizes rules of justice that predate cultural history. (CH)
