The understanding of nature and nurture within developmental science has evolved with alternating ascendance of one or the other as primary explanations for individual differences in life course trajectories of success or failure. A dialectical perspective emphasizing the interconnectedness of individual and context is suggested to interpret the…

Proposes a theory of development in which experience is directed by genotypes and in which genotypic differences affect phenotypic differences, both directly and through experience, via three kinds of genotype-environment effects. The theory adapts the three kinds of genotype-environment correlations in a developmental model used to explain…

Examined relationship between temporal contingency of maternal behavior and interactional quality. Found that although prompt responding was typical, the existence of individual differences indicated that this tendency was expressed in different communicative channels. The relationship between contingency and ratings of interactional quality was…

Bruner's (1973) review of infant skill development is updated and extended by (a) placing it in the context of recent motor learning research; (b) discussing the concept of efference in its most recent conceptualization; and (c) explicating certain implicit themes relevant to a theory of infant motor intelligence. (ED)

Maintains that there are core-specific and non-core-specific domains of knowledge, but that only the core-specific domains benefit from innate skeletal structures. Asserts that core skeletal domains are universally shared, even though their particular foci may vary. Emphasizes that individuals vary in terms of the noncore domains they acquire.…

Aimed to provide an extensive and integrative review of empirical studies of pretend play in children. Attempts were made to sort out what is known from what is supposed but unconfirmed, and to identify the theoretical implications of the former and the relevance of the latter. (Author/RH)

Notes that the Piagetian perspective admits the existence of interindividual differences but interprets them as noise masking the universal logical succession of structures, whereas the differential perspective views development as consisting of "vicarious processes." Asserts that the main aim of the "procedural studies"…

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…

Suggests ways to use dynamic systems analysis to illuminate the pluralistic and multidimensional model described by Larivee, Normandeau, and Parent (2000). Issues discussed include the characteristics of developmental transitions, such as hysteresis; nature of growth processes, such as hierarchical development or predator-prey interactions; and…

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…

Emphasizes the benefits of cooperation between researchers in developing a comprehensive model of cognitive development that considers the constraints of human brain structures and the interplay of general laws of development and individual differences in developmental pathways within the context of social and cultural environments. (Author)

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;…

Two experiments examined 12- and 17-year-olds' active selection of quality of feedback they wished from peers. Findings indicated that participants with positive self-perceptions sought feedback that was more positive than participants with negative self-perceptions and sought more positive feedback than expected by chance. Participants with…

Argues that extant research assessing relations between contextual factors and psychological disturbance has confused two different roles of context. Suggests that environmental factors are nonspecific stressors and elicit psychopathology, with specificity of expressed psychopathology governed by individual differences, and that context is…
