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)

Discussion of Piaget's three catagories of contradiction. (MS)

Attempts to refute Riegel's (1973) claim that Piaget's formal operations distort reality for the sake of logic. It is suggested that Piaget's figurative-operative distinction is dialectical and that Piaget's theory is valuable precisely for its resolution of how a person remains internally ordered while adapting to the external world.

It is suggested that the concepts of possibility and reflectivity have a variety of meanings, and that once these meanings are examined, the logical foundation for the…

Piaget's conceptualization of concrete and formal operations is presented. It is contended that Piaget has obfuscated logic, metaphysics and methodology. (MS)

A commentary on the sense of isolation and estrangement which commonly accompanies the relativism ushered in by formal operational thought, and a detailing of several regressive strategies frequently employed by adolescents in their efforts to accomodate to this plurality of solitudes. (JMB)

Suggests that although Piaget's psychological theory is developmental and dialectical in a general way, the lack of a developed philosophical basis leads to the subordination of a dialectical approach to static, anti-dialectical concepts. Hegel's theory of interaction and contradiction is examined to show that dialectical theory has a precise…

Presents a brief overview of research and developments in the study of formal operations thought since 1972 along with some speculations concerning future research directions. (Author/MP)

Provides clarification of the Piagetian theory of the development of conservation and reviews the state of knowledge regarding the theory. It is concluded that reasonable evidence exists suggesting that conservation by identity precedes and induces the emergence of conservation by inversion and compensation. (Author/DB)
