Piaget's last two works may add a new level of coherence and generality to his theories, which are grounded in an insight about the interdependence of reality and knowledge about reality. Piaget expanded Kant's epistemology to encompass three systems operating in the frames of biology, psychology, and culture. (MDM)

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;…

Because developmental theories of Vygotsky, Piaget, and Bandura are far more complex than much of the empirical work based on them, researchers have concentrated on relatively narrow aspects of each man's ideas, in the process magnifying the differences between them. Nevertheless, basic differences do exist in each theorist's conceptualization of…

Agrees with proposition of Tudge and Winterhoff in the previous article that the differences between the developmental theories of Vygotsky, Piaget, and Bandura have been exaggerated over the last 30 years. Perceived differences that distinguished these theories in the early 1960s have diminished dramatically, due in part to the later work of the…

Piaget's last writings in the 1980s and early 1990s contained both a coherent constructivist account of explanation in science and specific suggestions for revising the logic of operations as a logic of meanings. Demonstrates the interdependence of these two aspects of his work by examining the merits of Piaget's revised logical competence model…

Maintains that strengths of Olson and Torrance's work include its balanced focus on child and curriculum. Argues that the book neglects affective, social, and cultural aspects of development. Argues that the book's avoidance of ethnic categorization could encourage or justify avoiding issues of differences in human development and equity in…

Outlines Piaget's late ideas on categories and morphisms and the impact of these ideas on the comprehension of the inclusion relationship and the solution of arithmetic problems. Reports a study in which fourth through sixth graders were given arithmetic problems involving two known quantities associated with changes rather than states. Identified…

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…

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…
