Family socioeconomic status (SES) is strongly associated with children's cognitive development, and past studies have reported socioeconomic disparities in both neurocognitive skills and brain structure across childhood. In other studies, bilingualism has been associated with cognitive advantages and differences in brain structure across the…

Examined 10- to 13-year-old boys' development of knowledge structure and sport performance in tennis by comparing skills and knowledge of experts and novices. Experts focused on higher concepts and exhibited greater decision-making ability because of their more highly developed knowledge structure. (SAK)

Describes a theory of cognition which posits specialized structural systems (SSSs) that enable individuals to represent and understand domains of knowledge. Three test batteries assessed 12-16 year olds' abilities to think combinatorially, form hypotheses, design experiments, and construct models or theories. Suggests that the results of tests…

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…
