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…

Older interlocutors are more likely than younger ones to make pragmatic inferences, that is, inferences that go beyond the linguistically encoded meaning of a sentence. Here we ask whether pragmatic development is associated with increased activity in brain structures associated with inference-making or in those associated with Theory of Mind. We…

Mental representations of numerical magnitude are commonly thought to undergo discontinuous change over development in the form of a "representational shift." This idea stems from an apparent categorical shift from logarithmic to linear patterns of numerical estimation on tasks that involve translating between numerical magnitudes and…

The impulse to investigate the natural world is deeply rooted in our earliest childhood experiences. This notion has long guided researchers to uncover the cognitive mechanisms underlying the development of scientific reasoning in children. Until recently, however, research in cognitive development and education followed largely independent…

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.…

Notes that Nelson, Plesa, and Henseler's (1998) article addresses the issues of where social cognitive knowledge comes from, what form it takes, and whether "theory of mind" is an appropriate description of the social cognitive enterprise. Argues that researchers ought to get beyond the "theory" issue, and focus on the sources…

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…

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…

Investigated the emergence of class and propositional reasoning skills as a function of the developing ability to coordinate increasingly complex negation and affirmation operations with children from grades 1, 3, 5, and 7. Found that children's reasoning follows a logical development sequence and that different groups of items account for…

The developmental stages of writing can be related to Jean Piaget's final three stages of development (preoperational, concrete operational, and formal operational) and to the narrative, descriptive, explanative, analytical, and artistic rhetorical modes. As the child enters kindergarten or the first grade, narrative blooms. By this age most young…

Reviews four books: (1) "A Dynamic Systems Approach to Development: Applications" (Linda B. Smith and Esther Thelen, Eds.); (2) "The Psychology of Gender" (Anne E. Beall and Robert J. Sternberg, Eds.); (3) "Children's Understanding: The Development of Mental Models" (Graeme S. Halford); and (4) "Adolescent Storm…

Four experiments investigated children's ability to notice and remember events in which the acquisition of factual information occurs. Results indicated that children tend to report they have known newly learned information for a long time, suggesting that children have some understanding of knowledge acquisition, but not at the level of adults.…

Examined the nature of perceptual classification in children and young adults. Found that most children attend selectively to one stimulus dimension when making perceptual classification judgments. Suggests that this developmental trend does not appear to be a holistic-to-analytic shift but rather a trend toward greater consistency in following a…

Delineates the current consensus regarding the nature and the development of intellectual ability. Examines when one would expect general abilities to moderate the relationship among domain-specific and other processes. Reviews recent studies in which general abilities were used as independent variables or covariates. Suggests that generally,…
