Provides brief biographical sketch and describes Muchow's research contributions. Discusses the content of her investigation of the environmental experience of a group of urban children and their activities in diverse settings. (Author/SO)

Author claims that Piaget's account of the construction of reality needs modification and a shift in emphasis. (Author/MB)

A pretheoretical model of cognitive development is proposed which is based on the empirical establishment of Gagne's cumulative learning sequences. (Author)

Reviews relativity theory in physics to derive a relativistic metatheory applicable to life span developmental psychology. The discussion points out ways in which relativistic thinking might enhance understanding of life span development and epistemology. (Author/DB)

Five prototypic issues derived from a dialectical perspective are proposed: relationism, evolving reciprocity, probabilism, timing, and the nonequivalent temporal metric. It is argued that these issues, while not changing the scientific method, have implications for specific procedures. (Author)

Argues that learning is an invariant process best understood from a dialectical perspective which demands that learning be viewed as an interaction between the organism and the environment. This view is contrasted with traditional operant approaches and with a Piagetian approach. (Author/DB)

Attempts to integrate Piaget's conceptualization of the development of social knowledge with the position of dialectical psychologists. (BD)

It is suggested that the complexities entailed in an analysis of life span attachment require consideration of so many interacting variables that a systems approach of some kind is needed for a beginning integration. (MS)

Theories of legal socialization can be classified as either content or process models. The present paper suggests that the latter suffer from two major misconceptions: a lack of interest in the behavioral consequences of legal judgments, and the assumption that judgments are the causes of action. (MS)

Suggests some difficulties and challenges in understanding and teaching Piaget's new theory. Outlines some differences between Piaget's new and standard theories, such as the diminished status of the emergent skills that mark the onset of concrete operational thinking and the perception of achievements in concrete operations as empirical…

Examines the role attributed to cultural mediation in Piaget's and Vygotsky's theories. Mediation of human action by cultural artifacts was central to Vygotsky's account of human development, but less important for Piaget. Vygotsky's claims regarding social origins of individual mental processes need to be understood in light of claims regarding…

Piaget's theory has been characterized as descriptive and not explanatory, not qualifying as causal explanation. Piaget was consistent in showing how his theory was both explanatory and causal. Vygotsky also endorsed causal-genetic explanation but, on the basis of knowledge of only Piaget's earliest works, he claimed that Piaget's theory was not…

Briefly summarizes Vygotsky's life, the appeal and subsequent abandonment of his ideas in the 1960s, and renewal of interest in the 1970s and 1980s (often at the expense of Piaget). Praises van der Veer and Valsinger's book as a realistic picture of Vygotsky's background, life, and work, of the scientific and political context in Russia and of his…

Outlines what the terms "learning" and "development" meant in the theoretical framework on one important developmental psychologist--Vygotsky. Discusses his concepts of decontextualization and contextualization, which have implications for a possible developmental account of heterogeneity in human mental functioning. (ET)

Looks at the social-historical context of developmental and other social science research in the United States. Focuses on the impact of Freud's and Piaget's theories. Discusses the current research trend to turn to the ideas in humanities and literary studies that have remained concerned with human development in social-historical reality. (ET)
