Twelve two year olds were taught novel count nouns for related but unfamiliar objects. Children's interpretation of the relations between the nouns was mediated by the similarity of the objects, a result that suggests that, by age two, children have the conceptual and lexical abilities necessary for establishing hierarchical relations.

In four experiments, three, four, and five year olds were successful in solving perspective-taking problems when they were asked what object occupied a specified location with respect to a hypothetical observer. Results indicated developmental change in several important aspects of spatial performance. (BC)

Examined are first-year medical students' (n=160) explanations of complex concepts in cardiopulmonary physiology following a lecture series. The results revealed systematic misconceptions by the students in developing a pathophysiological model of the problem. The implications for science instruction within a medical curriculum are discussed.…

Discusses formalizing in mathematics and provides anecdotal illustrations of formalizing in a constructivist environment, using students aged 12 and 8 involved in fraction work. (Contains 19 references.) (MKR)

External memory strategies were investigated in 45 children (age 11) with mild mental retardation and children (ages 7 and 11) without mental retardation. In contrast to expected deficiencies in the use of strategies, results showed areas of overlap in strategy capabilities among the groups. (Author/DB)

Examined age- and skill-related differences among adult Bingo players, aged 19 to 74, who had from less that 2 months to over 20 years of playing experience. Subjects completed psychometric, cognitive, and experimental measures. Found no age-related differences on psychometric or memory measures, suggesting that Bingo playing experience may have…

This retrospective look at 14 years of working with gifted adolescents elaborates on 4 prominent and prevalent issues: those who are often socially isolated from their peers; fear for their future and the world's future at a higher level than would be expected for their age; get bored in typical academic settings; and seek "existential relief"…

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…

A constructionist theory is described that accounts for the knowledge-based inferences that are constructed when readers comprehend narrative text. Distinctive assumptions of the constructionist theory embrace a principle of search (or effort) after meaning. Literature in support of the theory is reviewed. (SLD)
