This systematic review synthesized current literature regarding the effect of physical activity (PA) interventions on brain structure (BS) and brain function (BF) in healthy children. This review followed the Preferred Reporting Items for Systematic Reviews protocols and used the Rayyan web for data extraction. Eleven experimental studies were…

This paper draws attention to the literature in the areas of learning, specifically, constructivism, conceptual change and cognitive development. It emphasizes the contribution of such research to our understanding of the learning process. This literature provides guidelines for teachers, at all levels, in their attempt to have their students…

Reports on connectionist models that simulated the formation of global-level and basic-level representations in young infants; revealed a global-to-basic order of category emergence; uncovered formation of two global-level representations--initial "self-organizing" perceptual level and subsequent "trained," non-perceptual…

Summarizes presentations given at a recent White House Conference which showed that early experiences, particularly in the first three years of life, have a dramatic impact on brain development. Includes presentations on such topics as parent education, brain functioning, quality caregiving and child care services, and early intervention programs.…

Argues that the limited resources with which organisms start their development make possible certain kinds of learning which otherwise would be highly problematical. Discusses limitations of the cognitive structure of the organism, learning, and its problems in connectionism. Maintains that the knowledge gained from efforts to overcome problems…

Comments on Lewis's ideas about reconciling stage and specificity in neo-Piagetian theory in this issue. Focuses on whether general stages, domain specificity, and individual diversity are compatible from a nonlinear, dynamic perspective. Suggests that, by using catastrophe theory, intra- and interindividual diversity and domain specificity can be…

Assesses three papers in this volume, those by Wellman and Estes, Olson and Torrance, and Hall and Nagy, for their treatment of the following: (1) definition of semantic space, (2) defining children's processes of understanding that space, and (3) describing the contexts in which cognitive language is used. (AEW)

This document describes the construction/simulation software called Stella which can be used in the investigation of dynamic causal models. Topics considered are its built-in perspective of system dynamics and capabilities, its potential drawbacks, and its cognitive implications for educational applications. (JJK)

To resolve tension between general stages and conceptual specificity in neo-Piagetian theory, R. Case introduced the idea of central conceptual structures. To resolve difficulties of separating developmental level and conceptual diversity, this article reconceptualizes central conceptual structures as self-organizing systems that stabilize in…

Comments on Lewis's ideas about reconciling stage and specificity in neo-Piagetian theory in this issue. Summarizes R. Case's central conceptual structure and its relation to other neo-Piagetian theories. Notes similarities between Lewis and Piaget, suggesting that differences adhere to a limited number of general laws instead of being…

The application of Piagetian theory to educational practices encounters a series of major difficulties. The main focus of this paper is on the notion of general stages, which has been under attack in numerous studies. Organized in four parts, the paper: (1) discusses the problem of the existence of general stages and of a developmental…

Argues that reasoning is not governed by mental logic or models. Proposes new operational semantic theory, in which reasoning is based on children's operational understanding of key terms in a given problem. Reports results of a study of class inclusion in which dramatic differences in performance were found as the result of linguistic context.…

Examines a general developmental hypothesis concerned with children's understanding of perceptual experience, memory, intentions, and emotions. It is hypothesized that young children view the mind as passive in relation to the external world and regard external events as determining subjective experience, whereas older children know many ways that…

Reviews research linking social and cognitive processes, exploring implications for schooling and teacher education. The social basis of cognitive development is examined, highlighting Vygotsky's work and major aspects of his theory. Implications of sociohistorical perspectives on aspects of schooling are examined, and promising practices related…

Presents descriptions of play reflecting recent theories, including the psychoanalytic works of Freud, Erikson, and Peller; Piaget's developmental theory (with discussion of Sutton-Smith); and the views of Smilansky and Parten. (AS)
