Investigated the relationship between psychometrically defined brightness and cognitive development within Piaget's stage theory. Subjects were fifth- and seventh-grade boys. (SDH)

Argues that developmental psychologists need attitudes, methods, and conceptual schemes that integrate the distinctive contributions of both nature and nurture in order to study change and consistency in developmental functions, as well as individual differences in behaviors of interest. A conceptual scheme for early mental development is…

Focuses on the conceptual implications of analyses of individual differences in francophone post-Piagetian research. Maintains that these analyses are preoccupied by the "American question" of measurement and method, instead of attempting a theoretical account of the issues raised by intraindividual and interindividual variability in…

Offers a developmental perspective on research risk that emphasizes the idea that some risks to children decrease with increasing age; some increase as the child matures; some change in a curvilinear fashion; and some remain essentially stable. Suggests that researchers are in an optimal position to safeguard children's rights. (RH)

Presents French-speaking researchers' contribution to differential developmental psychology. Traces methodological and theoretical transformations necessary for understanding individual differences within a general theory of cognitive development. Provides overview of pluralistic and multidimensional model of cognitive functioning/development…

Discusses some general-causal assumptions of current neo-Piagetian research and compares them with those of French European developmentalists with regard to individual differences, developmental stages, and methodology. Discusses the developmental unfolding of mental attentional mechanisms. Highlights developmental theory problems for the…

Suggests future directions for study of sensitivity and its impact on early psychosocial development: (1) renewed attention to growth of attachment in context of other developing features of the parent-child relationship; (2) factors that moderate impact of sensitivity on developing security; (3) origins of individual differences in sensitivity;…

Discusses responsibility of developmental scientists to convey the complexity of development lest oversimplified popular accounts gain credibility. Presents a model of development elaborating on the role of experience in relation to constitutional, cultural, economic, and social factors contributing to children's development. Discusses importance…

Argues that an evolutionary account provides insight into developmental function and individual differences. Outlines some assumptions of evolutionary psychology related to development. Introduces the developmental systems approach, differential influence of natural selection at different points in ontogeny, and development of evolved…

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…
