Eighty-three children from grades 2 through 5 were administered measures of social egocentrism and moral judgment. Methodological improvements in the moral judgment measure were introduced. (Author/MP)

Assesses children's understanding of the impact of length, noise, age, and time on performance of three cognitive activities: memory, communication, and attention. Subjects were 18 preschool children and 18 first graders. (MP)

Two experiments were conducted to test the generalizability to children of a theory of analogical reasoning processes, originally proposed for adults, and to examine the development of analogical reasoning processes in terms of five proposed sources of cognitive development. (MP)

Investigates the effect of various strategy-modeling techniques on the performance of both young children and elderly adults on the 20 Question Task. (Author/MP)

Proposes that cognitive developmental stages can be accounted for in terms of information processing factors which limit the highest level of cognitive system which children can attain at any given age. Delineates four progressively more complex levels of cognitive mediation of the environment. Two experiments which support the developmental model…

Four studies tested claims that young children are inhibited in attempts to change drawings because of constraints by order in which representational elements are drawn. Found that procedural rigidity levels did not predict preschoolers' performance when asked to change their representation and that preschoolers could change rigid sub-procedures…

Three studies examined children's understanding of their authority over their self-knowledge. Findings suggest that the shift from reliance on adults to self occurs between 5 and 10 years of age, with parallel development in judging own and other people's self-knowledge. Children between ages 5 and 7 could differentiate between information about…

Investigated development of reasoning about the teaching of values in school and family contexts among 8-, 10-, and 13-year olds and college students. Found that children and young adults' reasoning is multifaceted and distinguishes between moral values that reflect justice, rights, and moral character traits and other forms of desirable…

Examines the development of young children's analysis of spatial patterns--specifically, hierarchical letter and geometric forms. Suggests that although children as young as four years of age demonstrated substantial analytic competence, their ability to integrate the parts of the spatial array to form a coherent whole was weaker and more easily…

Examined claim that associations between emotional responses to maternal separation and cognitive performance would change with cognitive development over the first year. Emphasized the measurement of separation and reunion distress. Found that emotional responses and cognitive performance may be linked by individual differences in self-regulation…

Explores the extent to which third graders are consistent in their definitions and explanations of nine social qualities. For several qualities, children's definitions and explanations followed developmental predictions. For other qualities, definitions and explanations were attributed to previously identified moderation variables and age of…

Examines interactions between 48 mothers and their two- , three-and-a-half-, and five-year-old children during book reading sessions. Formal reading and interchange about story content increased with age and book familiarity, while labelling decreased with age and book familiarity. (RJC)

Teaching students decision-making skills is integral to many drug education programs. Conducted series of studies examining elementary and secondary school students' attitudes toward making decisions. Found different age groups perceived making decisions differently. Suggests practitioners need to take maturational levels into consideration when…

Examined whether speech rate is related to the amount recalled and if developmental increases in speech rate allow faster rehearsal with age, and hence, greater recall. Found that the group relationship was clear and replicable but that speech rates of individual children were not good predictors of those children's memory spans; age was found to…
