This final essay in a five-part series examining Piaget's structural developmental psychology suggests that a psychological theory which integrates aspects of developmental structuralism within a critical social framework can be developed. (Author/RH)

Outlines how levels of the interpretation of reality and categories of a naive theory of action that constitute these levels are differentiated and coordinated in a specific developmental sequence. Subsumed within this theoretical framework are the distinction between action on physical objects and social interaction and the distinction between…

Briefly discusses similarities and differences between social and physical knowledge. Argues that the study of social cognition cannot be derived from, nor reduced to, the study of physical cognition, and that the social origins of knowledge need to be emphasized more in contemporary developmental theory. (Author/SS)

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…

Compares Piaget's and Vygotsky's interpretations of transmission and transformation. Notes that differences are apparent in the preformation of knowledge, availability of a third alternative to nature and culture, and unity and identity in social interaction. Vygotsky was concerned about the novel transformation of the learner; Piaget, with the…

Chronicles Piaget's and Vygotsky's criticism of each other's ideas on childhood egocentrism. Notes that genuine, critical dialog failed to develop because Piaget did not reply to Vygotsky's criticism at first. Five reasons for his reticence are considered: (1) a language barrier; (2) lack of knowledge; (3) quality of the criticism; (4) ideology;…

Notes that Nelson, Plesa, and Henseler's (1998) article addresses the issues of where social cognitive knowledge comes from, what form it takes, and whether "theory of mind" is an appropriate description of the social cognitive enterprise. Argues that researchers ought to get beyond the "theory" issue, and focus on the sources…

Discusses difficulties in measuring interpersonal understanding, ego development and moral development. Compares Loevinger's and Selman's theories, showing how cognitive and sociocognitive structures may be used to reconstruct many ego development test items. (NH)

Suggests that the central focus of the article by Raver and Leadbeter (PS 521 712) in this issue is the ways individuals know. Examines two ways of knowing, verbal responses to questions and action without verbal response; and outlines a four-level developmental sequence of knowing that develops from one's own knowing to having a perspective on…

Examines Piaget's and Vygotsky's conception of the relation of the social to the individual, including individualism versus holism, Piaget's alternative of relationalism, and Vygotsky's views of the nature of the social. Suggests that Piaget's denial and Vygotsky's advocacy of explanatory emergence leads to the question of domain-general versus…

Discusses two related problems generated by Piaget's psychology of decentered knowing. Subjectivity, consciousness, and self-consciousness are ruled out; the dynamic transformation of society through history is reduced to triviality. (Author/DB)

Claims that mind and mental objects form a societal mental structure enabling children to assimilate the society and become co-constructing members. Cites evidence that competence to create mental objects, symbols, and meanings separated from action is the evolutionary evolved human capacity for society and culture. Vygotsky's "natural"…

Recent research has established closer links between language, cognition, and social life than Piaget or Vygotsky imagined. Connections have been established between object permanence development and acquisition of disappearance words and the quantity and quality of child-adult joint attentional social interactions and children's early word…

Considers the mind of the epistemic psychologist, a constructivist knowledge creator within a scientific framework, guided by the social world of scientific institutions. Suggests that Piaget and Vygotsky shared respect for complexity of phenomena and were consistently developmental in their theories. A reconsideration of their common heritage…
