Most research on children's conception of death has probed their understanding of its biological aspects: its inevitability, irreversibility and terminal impact. Yet many adults subscribe to a religious conception implying that death marks the beginning of a new life. Two recent empirical studies confirm that in the course of development, children…

This paper argues that the metaphorical representation of concepts and the appropriation of language-based construals can be hypothesized as additional sources of conceptual change alongside those previously proposed. Analyses of construals implicit in the lay and scientific use of the noun "energy" from the perspective of the theory of conceptual…

The theory of conceptual fields is a developmental theory. It has two aims: (1) to describe and analyse the progressive complexity, on a long- and medium-term basis, of the mathematical competences that students develop inside and outside school, and (2) to establish better connections between the operational form of knowledge, which consists in…

Philosophers and scientists seeking to conceptualize consciousness, and subjective experience in particular, have focused on sensation and perception, and have emphasized binding--how a percept holds together. Building on a constructivist approach to conception centered on separistic-holistic complexes incorporating multiple levels of abstraction,…

While recognizing major contributions of the contemporary theory-of-mind framework, we identify conceptual and cultural gaps with respect to its inattention to deontic considerations. The framework has tended to portray behavior as purely self-directed, thereby neglecting everyday reasoners' understanding of behavior as normatively based. However,…

The developmental psychology of mathematical thinking and the clinical interview method can make major contributions to education by transforming the process of formative assessment--the attempt to use information concerning student performance, knowledge, learning potential, and motivation to inform instruction. The clinical interview is a…

Replies to commentaries by Mandler (1988) and Rochat and Striano (1988), focusing on Mandler's comments. Maintains that their disagreements are the result of deep meta-theoretical differences regarding a representational theory of mind rather than misrepresentations of fact. Discusses how their meta-theoretical differences result in several basic…

Presents a model of the development of desociocentering, decentering relative to the social group, which is based on Piagetian research and theory and Wernerian concepts. (Author/SS)

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

A broad literature review revealed that younger children are more likely to categorize objects along complimentary dimensions than older children who tend to categorize according to similarity. This developmental change is discussed in terms of etiology--internal organismic changes or environmental changes. (DP)

Reviews Karmiloff-Smith's "Beyond Modularity," suggesting that her work highlights phenomena that seem counter intuitive when regarded from current developmental frameworks, and advocates that understanding them requires more complex perspectives than can be supported by either extreme nativist or domain-general models of cognitive…

Reviews "The Mind's Staircase: Exploring the Conceptual Underpinnings of Children's Thought and Knowledge," edited by Robbie Case. A main thesis of the book, which discusses theoretical issues and presents empirical evidence, is that children's cognitive development is guided by central conceptual structures, or networks of concepts that…

Presents and reviews Piaget's recent work on equilibration. (BD)

Maintains that Muller and Overton (1998) misrepresent her theory of infant concept formation in infancy, makes corrections to their representation, and notes that her theory was developed in part because of the lack of detailed mechanisms in Piaget's theory to account for concept formation. Argues that Muller and Overton's proposed alternative…

To learn how children acquire "metalinguistic competence," the development of the concept of "the word" was experimentally studied in four- to ten-year-olds. (Author/SDH)
