Argues that the reduction of competence models to performance models is countered both by epistemological arguments and by examining the weakness of supposed refutations of Piaget's logical competence model. Points out flaws in Piaget's position. (Author/RH)

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)

Comments on Moshman's discussion, in this issue, of reasoning as self-constrained thinking, arguing that differences in type of reasoning constraint probably reflect different knowledge bases but do not necessarily imply different processes. The fact that different tasks require different kinds of knowledge does not mean that different processes…

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…

Proposes a theory of reasoning and outlines four general types of reasoning (case-based, law-based, coherence-based, and dialectical) based on the constraints the reasoning seeks to honor. The development of reasoning is presented as a continuing construction and reconstruction of self-constraints and justifications for those constraints,…

Offers a theoretical account of moral rationality within a rational constructivist paradigm examining the nature and relationship of rationality and reasoning. Suggests progressive changes through developmental levels of moral rationality. Proposes a developmental moral epistemology that accommodates moral pluralism to a greater degree than does…

Suggests that constructivist rationality may be more pervasive across cultures than Moshman commits to. Proposes that rationality is not always adequate, and there is a need for essentially moral labor, such as differentiating moral from nonmoral or analyzing differing moral constructs and their potential coexistence, coordination, and structural…
