Investigates the development of understanding of quantity in 36 children with Down's Syndrome. Findings confirmed similarities in sequence of development between Down's Syndrome children and nonretarded children. Down's children who received training recognized conservation of continuous and discontinuous quantity. (RJC)

Research indicates that early cognitive intervention typically yields short-term advantages for children and their parents. Long-term effects are not maintained unless: intervention sets off a chain of positive consequences, and the whole life span is taken into account. Long-term change efforts should incorporate familial and psychosocial…

Discusses the results of a study designed to determine the metalinguistic awareness of 45 preschool children (15 elementary school children were included to determine the effect of school attendance). The children wre given 3 "metalinguistic" tasks: judging the acceptability of sentences, dividing words, and judging the coherence of…

Introduces the common theme among the papers presented in this issue, the development of working memory. Underlines the two different approaches presented. The neo-Piagetian perspective attempts to capitalize on the insights of Piaget's work by proposing information-processing accounts of cognitive development. The second perspective stems from…

Attempts the theoretical rapprochement of two theoretical constructs on working memory, neo-Piagetian models and Baddeley's model. Summarizes both types of models, then discusses their similarities and differences. Presents the results of a longitudinal study that supported the idea that these models might be complementary rather than…

Studies gender patterns in five- and six-year-old children's social interactions with one another and variables that may influence these patterns. Findings suggest that differences between boys and girls in the use of aggravated behavior in interaction style is strongly influenced by the nature of the activity being performed and by the gender of…

Presents background information about Vygotskian theories. Describes Vygotsky's Zone of Proximal Development (ZPD). Discusses a model of attitude development that incorporates the ZPD, meta-awareness, the components of an attitude, and factors influencing attitude development. Suggests educational implications. (45 references) (MDH)

Examined the relative influence of age- and schooling-related experiences on story memory and storytelling. The age-related effects are attributed to general development in memory capacity and deployment of cognitive resources, whereas schooling-related effects are attributed to restructuring of the story representation in memory. (WP)

Two experiments investigated whether preschoolers attend to appearance instead of taxonomic relations in sorting sets of objects with conflicting appearances and taxonomic relations. Found that training and instructions have a significant effect on children's preference for sorting according to taxonomic relations or appearance, and that both…

Summarizes three studies on the effects of physical environment on preschool children's play and cognitive development, and discusses implications for classroom design. Notes that size of play area, and the extent to which the size of structures in that area was proportional to children's size, affected the rate at which children entered complex…

Highlights Paley's contributions, particularly her work in developing the vision of the narrative classroom. This vision includes using a combination of acting, writing, and directing to get children to work together and develop ideas in small settings. Paley's methods and insights illustrate these concepts and classroom life in an important way…

Describes the use of a graphic organizer--webs--to help students learn to connect concepts in mathematics. (MKR)

Examines research on the importance of understanding children's biological timetables for mind and brain development, and forces that can threaten this neurodevelopmental timetable during critical periods. Discusses the brain's adaptability, and focuses on the importance of knowledge derived from the study of special populations for understanding…

Discusses the nature and extent of problem of prenatal drug exposure. Expresses concern about the increase in number of women of childbearing age testing positive for drug use. Explains the social, cognitive, behavioral, and motor deficiencies resulting from such drug exposure and consequent issues and recommendations for early childhood…

A study with 29 preschoolers showed that a statistically significant number of them successfully reassigned tags in counting (ordinality) but failed to predict that differently ordered counts would produce the same outcome (cardinality). Results indicated that children may not entirely understand implications of their counting actions. (Contains…
