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…

A social development theory of self is introduced as a framework for developmental psychopathology. Built on some of Piaget's principles, the theory is taken into the social domain and used to define the movements of self and important others throughout life. (PCB)

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…

Piaget's studies clearly highlight two qualitative advances made during the preoperational period. The first is the breakthrough of representational intelligence, beginning around 2 years of age. The second is the emergence of coordinated representational thought, beginning around 4 years of age. This paper focuses on the second advance, which…

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;…

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…

Traces continuities between current approaches and earlier traditions in developmental psychology. Contends that current work often ignores commonalities with previous work within psychology. Explores the fate of Piaget's clinical method and its continuities and contrasts with current approaches. Maintains that the conflict generated by the…

Examines development of representational thought from the perspective of Jean Mandler's image-schema theory and an action-theoretical approach derived from Piaget's theory. Concludes that empirical findings fail to support hypotheses of early onset, and that representational development is more adequately interpreted within the context of an…

The application of Piagetian theory to educational practices encounters a series of major difficulties. The main focus of this paper is on the notion of general stages, which has been under attack in numerous studies. Organized in four parts, the paper: (1) discusses the problem of the existence of general stages and of a developmental…

Compares and contrasts the concept of social constructivism derived from work of Piaget and Vygotsky and examines their implications for young children's learning. Emphasizes the nature of social interaction with adults and children and its role in the construction of shared knowledge. Suggests that similarities in these two approaches are more…

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"…

Discusses the influence of Levy-Bruhl's analysis (1910) of "primitive" mentality on Piaget's research and theory contrasting child and adult ontology and logic. Maintains that parallels between their research designs substantiate Piaget's explicit references to Levy-Bruhl. Suggests that their conceptual kinship has implications for an…

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…
