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…

Factors that influence the incidence of utilization deficiencies and other recall/strategy-use patterns on a strategic memory task were evaluated in two hundred and fourteen 7- and 9-year-old children. Both utilization deficiencies and the incidence of children showing increases in both recall and strategy use over phases were more likely to be…

Cumulative experience with a variety of symbolic artifacts has been hypothesized as a source of young children's increasing sensitivity to new symbol-referent relations. Evidence for this hypothesis comes from transfer studies showing that experience with a relatively easy symbolic retrieval task improves performance on a more difficult task.…

Examines research in folkbiology (commonsense understandings of plants and animals) to argue that several lines of comparative research are needed to understand the acquisition of folkbiology in particular and conceptual development in general. Asserts that comparisons are needed between children and adults within a given society, between adult…

In a series of experiments, young children were asked to compare the quantities of classes of objects under two conditions: (1) when one of the classes of objects is a subordinate of the other (the traditional class-inclusion problem), and (2) when the terms refer to exclusive sets but different levels of generality. (Author/RH)

Examined children's, adolescents', and college students' judgments of children's and adults' rights to freedom of speech and religion in societal, school, and family contexts. Found that endorsements of these freedoms were increasingly affected by social context and agent with age. College students were less likely than others to affirm children's…

Discusses ways in which researchers have examined the role of social and emotional factors in cognitive functioning and development to uncover additional sources of variation to explain interindividual and intraindividual differences in cognitive development from within a Piagetian framework. Considers the implications of recent Francophone…

Argues that the operating characteristics of perceiving and remembering provide a foundation for progress on detailing the processes through which knowledge is realized in real-time tasks and in detailing the processes of developmental change. Includes three examples to illustrate how forming developmental hypotheses in terms of perceiving and…

Study One examined Swedish and American children's understanding of what constitutes fair criteria for the distribution of goods (i.e., distributive justice). Study Two compared children's distributive justice in family and peer contexts, and Study Three attempted a longitudinal assessment of distributive justice reasoning in two different…

Examined 5- to 12-year-olds' judgment regarding the behavior of balance scales and other levers whose arms varied in a causal or a noncausal variable. Results indicated age-related increases in correct judgments about the influence of physical features of objects at an earlier age than about spatial relations between objects. (MOK)

Calls for a process-oriented approach to study of categorization in infancy. Maintains that further understanding of infant categorization and its changes with development requires a more direct assessment of infants' category formation. Argues that two research directions will enhance understanding of categorization: (1) contextual variations on…

Used hierarchical linear modeling to explore the effects of the social context of Chapter 1 prekindergarten classrooms on 4-year-olds' learning. Found that children made smaller gains on the Preschool Inventory over the preschool year in classrooms with higher concentrations of minorities, children with special needs, recent immigrants, and…

This study explored judgments and reasoning of Chinese 13- to 18-year-olds regarding making decisions involving children in peer, family, and school contexts. Findings indicated that judgments and reasoning about decision-making varied by social context and by the decision under consideration. Evaluations of procedures became more differentiated…
