Contrasts work of Leontiev and Vygotsky. Suggests that Leontiev concentrated on social activity as a whole, whereas Vygotsky made semiotic mediation through culturally developed symbols a central aspect of his analysis. Maintains that they shared a philosophical base and that Leontiev used Vygotsky's ideas as a starting point to explore human…

Comments on revision of Piagetian theory of reciprocity in forgiveness by Enright (PS 522 365) in this issue. Reviews relationship of Enright theory to previous research. Suggests that forgiveness may require moral insights in addition to reciprocity, but reciprocity appears central to children's and adults' understanding of forgiveness. Provides…

Reconsiders interpretive and theory versions of children's theory of mind. Shows that many college students provide interpretive explanations on theory of mind tasks and that young children rely on background experientially-based knowledge to interpret such tasks. Argues that a logical-causal theory of human action based on mental states is a…

Considers the issue of parallels between ontogeny and phylogeny from an historical perspective. Discusses such parallels in relationship to two ontogenetic principles concerning recapitulation and sequence of stages. Differentiates between Piaget's use of the idea of recapitulation and Haeckel's biogenetic law. (Author/RH)

Argues that ontogenetic and phylogenetic theories are related and that such a coupling can be established only in reference to a metatheory. The metatheory is construed in terms of a combination of logical coherence and requirements necessary for generalization as well as comprehensive, philosophical representations of living beings (e.g.,…

Contrasts holism, elementarism and Piaget's rationalism. Suggests Piaget's views are close to those of transactionalism and that the key difference between Gestalt holistic structure and Piagetian operatory structure is whether the composition laws are additive or not. Piaget's version of structuralism (relationalism) is distinctive in being…

This paper is intended as a critique of the proposition that the multiplicity of available psychological theories is divisable into a much smaller set of incompatible and mutually exclusive world views. (MS)

This paper shows how an open-ended nonlinear dialectic process can be depicted as a self-linearizing form which reveals transition structures as nodal points of self-reflection. (MS)

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…

Proposes a cognitive mechanism that makes forgiveness possible. Revises Piaget's theory that ideal reciprocity is the underlying cognitive operation that makes understanding and appreciation of forgiveness possible. Draws on modern philosophical inquiry, empirical study, and theory to argue instead that abstract identity provides--philosophically…

In this article, we trace the development of Hatano's research, focusing on the core of his research interest, namely, expertise, conceptual development, and classroom learning. He held both Piagetian constructivist views and Vygotskian sociocultural perspectives in balance, and preferred to study human cognition executed in everyday life. This…

This paper builds on Hatano and Inagaki's pioneering work on the role of experience and cultural models in children's biological reasoning. We use a category-based induction task to consider how experience and cultural models shape rural and urban children's patterns of biological reasoning. We discuss the implications of these findings for…

Giyoo Hatano was an international scholar--an adaptive expert himself. His creative methodologies and theoretical insights have enriched the work of researchers in many countries. How Hatano lived his life and treated others provides enriching insights as well. In this essay, we focus on "adaptive expertise", one of Giyoo Hatano's major…

Toward the end of his life, George Herbert Mead developed a theory of perspectives that may be used to reinterpret his social, developmental psychology. This paper attempts such a reinterpretation, leading to the emergence of a theory of perspective taking in early childhood that looks quite different from that which is assumed in most extant work…

Criticizes the operant approach to the study of life span development from a theoretical behaviorism view. It is argued that the operant approach is too limited in its scope to enhance significantly the conceptualization and understanding of life span development. (Author/DB)
