Adult performance of high ability individuals has seldom been researched. Current results suggest that adult excellence occurs at lower rates than high ability individuals identified in their infancy or youth, with few cases of high intellectual abilities among adults that yield excellence products. This paper focuses on the analysis of the…

This article explores theoretical and methodological issues associated with task-based interviews conducted with pairs of children. We explore different approaches to interviews from sociological, psychological and subject-based perspectives. Our interviews, concerning mathematical questions and carried out with pairs of 10 and 11-year-olds, are…

In an accompanying study, Alibali et al. [Alibali, M. W., Ockuly, K. M., Fischer, A. D. (2009) "Learning new problem-solving strategies leads to changes in problem representation." "Cognitive Development, 24," 89-101.] present an important experimental result: introducing a new strategy can affect conceptual aspects of children's problem…

How do people reason about issues related to child and youth development? Are the patterns of reasoning in the lay public significantly different from the way experts reason about the issue? What can the anthropological theory of cultural models bring to efforts to improve the public's understanding of child and youth development? In this article,…

This article explores turning points and transitions emerging in the life course of children with disabilities and their parents.

Reports four experiments focusing on Piaget's claims that conservation and transitivity concepts are experienced as logically necessary truths. Two experiments examined feelings of certainty and necessity in college students presented with Piagetian tasks. Two other experiments extended these procedures to children and the issue of developmental…

Investigated the relationship between children's knowledge structures for peers and externalizing behavior problems. Evaluated initial aggression level in years 1, 6, and 9 of longitudinal study; evaluated social knowledge structures in year 6. Found that knowledge structures were related to children's concurrent externalizing behavior and…

Argues that assessment based on the content of a reading curriculum will not necessarily promote more effective instruction than one not so based. Focuses on reading ability, individual differences in the ability to read, instruction in reading, curriculum-based assessment of students' skill in reading, and assessment of comprehension. (RJM)

Proposes that conceptual change is constrained by the child's conceptual structures and the structures inherent in problem-solving tasks. Uses a microgenetic case study and group data to examine how interaction between strategies children bring to a task and the detailed task structure redirect children's attention and create the possibility of…

Children's analogical reasoning has traditionally been measured by classical four-term analogy tasks or problem-solving tasks. Current theories of analogical development and the evidence on which they are based are reviewed. It is concluded that structural views of analogical development are wrong, and knowledge-based accounts of what develops are…

Spearman's "Law of Diminishing Returns" states that the g saturation of a test is greater for individuals with lower, rather than higher, test scores, and that it decreases with age. A common methodological problem in testing Spearman's "Law of Diminishing Returns" with respect to ability differentiation is how to create the…

Advances an important new way to conceptualize and assess the causes of parental behavior by examining how internal working models influence parents' beliefs and behaviors. Suggests that a primary source of parents' feelings of self-efficacy with respect to child rearing, as well as their explanations for their children's misbehavior, is the…

Highlights thematic continuities among the otherwise diverse research approaches presented, for example, synthesis of different theoretical perspectives of parent beliefs, or the context in which parental beliefs…

The developmental increase in the ability to solve problems is a puzzle. Does it come from basic changes in mental skills, or is it a matter of practice? This book from the Developing Child series synthesizes recent research examining children's problem-solving skills development. Chapter 1 presents the major themes: (1) there is increasing…
