Discusses the logical discontinuity between object and personal knowledge. Proposes an extension of Piaget's subject-object equilibrium to a dialogic situation between an ego and an alter. Suggests that this structural model provides a scheme by which differences in adulthood between adaptive and maladaptive cognitive change can be clarified.…

Argues that the status of the concept of equilibration is classified by considering Piagetian theory as a research program in the sense elaborated in 1974 by Lakatos. A pilot study was made to examine the precision and testability of equilibration in Piaget's 1977 model.(Author/RH)

Criticizes the distinction between lower and higher psychological processes in Vygotsky's cultural-historical theory. Shows that Vygotsky separated these processes too sharply and that his conception of lower processes as "natural" and "passive" is false. Suggests that these shortcomings can be overcome within the…

Explores implications of two cognitive development perspectives for characterizing ontogeny of causal reasoning. Reviews literature on causal reasoning in the preschool years and concludes that the hypothesis of an invariant causal scheme is only partially correct. (Author/SO)

Provides an alternative conception of postconventional moral development which fits existing data on late adolescent and adult moral judgment better than Kohlberg's higher stage descriptions. Data is from a longitudinal study of 26 undergraduates at Harvard. (Author/SS)

Interviews with adolescents revealed that they have a complex "divided metaphysics" of subjectivity, based on a dualistic view of reality versus appearance. Certain conceptual methodological issues surrounding research into self identity are discussed. (Author/DB)

Discusses difficulties in measuring interpersonal understanding, ego development and moral development. Compares Loevinger's and Selman's theories, showing how cognitive and sociocognitive structures may be used to reconstruct many ego development test items. (NH)

Reports a two-year longitudinal study of 55 adolescents and young adults who were divided into three groups and given Reflective Judgment Interviews and the Concept Mastery Test to investigate sequentiality of reflective judgment stages. Results indicate support for seven hypothesized shifts in epistemic assumptions over time.(Author/RH)

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…

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…

A dialectical schemata framework was used to interpret, code, and compare 27 interviews on the nature of education with freshmen, seniors and faculty members at a small, highly selective liberal arts college in order to provide a description of the organization of dialectical thinking and its presence in mature thought. (Author/DB)

Investigates differences between adolescents and older adults in their explanations of linguistic metaphors. Adults displayed a synthesizing, integrative perspective, while adolescents displayed an analytic perspective in their explanation of metaphors. (Author/SS)

Summarizes the theory of psychological differentiation and reviews recent cross-cultural research on the roles of child rearing, culture, and ecology in the development of individual, group, and sex differences in the field dependence-field independence cognitive style component of psychological differentiation. (SS)

Investigates the effect of various strategy-modeling techniques on the performance of both young children and elderly adults on the 20 Question Task. (Author/MP)

Describes four kinds of pretend play inhibition observed in children from three to nine years of age. Proposes hypotheses regarding potential causes and developmental sequelae of pretend play difficulties, in both cognitive and socioaffective realms. Discusses the implications of children's pretend play inhibition for examining relationships…
