Pretend play is often hypothesized in a global sense to be an effective context for young children's learning, but there is much still to learn about whether all types of information can be learned equally and whether all types of pretend play are equally beneficial. The present study tests whether preschoolers can learn a simple, novel causal…

Young children's naive beliefs about physics are commonly studied as isolated pieces of knowledge. The current paper takes a different approach. It asks whether preschoolers interlink individual beliefs into larger configurations or Gestalts. Such Gestalts bring together knowledge such as how an object's mass relates to its sinking speed, how an…

Children were asked to judge the life qualities of a stimulus, justify their judgment, and judge again, after being given an anomalous probe. Analysis indicated younger children were unable to adhere to an original judgment when probed, while older children were. Results may reconcile previous empirical discrepancies in Piagetian research.…

The study, with 57 children (ages 3-6) enrolled in 3 Head Start classes, demonstrated that short-term, large-group basic concept instruction combining direct instruction with interactive and incidental teaching techniques resulted in significantly improved scores on the Boehm Test of Basic Concepts-Revised.

This study explored children's development of a "mental time line" and considered the propositions that younger children view the temporal domain as bi-polar, while older children display signs of using finer gradations on their mental time ruler that approach conventional structures of clock and calendar time. Subjects were a group of…

A study of the development of representations of economic life in 110 young children of 3 to 5 years of age is reviewed to identify the sources of the children's representations. In addition to noting the importance of the public availability of adult representations, the results indicate the significance of developmental processes. In particular,…

Five studies investigated preschoolers' understanding of the biological germ theory of illness compared to that of 6- or 10- to 11-year-olds. Found that the younger the child, the less likely he or she was to judge germs as causes of illness. Studies undermined claim that preschoolers understand germs to be uniquely biological causal agents. (JPB)

The study examined the effectiveness of enhancing perceptual differentiation in the training of four developmentally delayed preschool children who were so low-functioning that they did not demonstrate oddity responding (ability to choose one distinct stimulus from a group of identical stimuli). Instead of the Arabic numerals used in the original…

This study investigates spatial and conceptual role-taking at the preschool level to determine the components of and relationship between these two forms of role-taking. A total of 80 children between 3 and 5 years of age were tested individually on four spatial tasks and five conceptual tasks and rated on the levels of egocentrism employed.…

Three tests were conducted to contrast the ability of bilingual and monolingual children to label and relabel objects. The findings show that bilingual subjects were significantly better than monolingual subjects, supporting the view that preschool bilingual education stimulates children's cognitive development, and enhances their self-concept.…

Some of the literature related to preschool mathematical experiences and their effect on the development of how the child perceives the relationships of mathematics is reviewed. (MP)

Results of 3 sentence-interpretation experiments involving 180 preschoolers suggest that very little explicit syntactic knowledge is needed to give children some structural clues to verb meaning. Sentence structure appears to have a meaning of its own that can be applied by analogy to the child's conceptual representation. (SLD)

Two experiments compared preschoolers' awareness of knowledge transitions involving behavioral changes to those involving vocabulary or general knowledge changes. Found that children tended to report they had learned something new when novel information was behavioral (e.g., counting in Japanese) and tended to claim prior knowledge when the novel…

Investigated in 3 studies whether 2- to 4-year-olds make accurate causal inferences on the basis of patterns of variation and covariation. Found that all three age groups considered information from various patterns of variation and covariation in judgments regarding two objects and activation of a machine. Three- and 4-year-olds used the…

This study investigates acquisition of two aspects of the meaning of color terms: semantic organization and reference. A longitudinal, repeated measure design was used, and data were collected from 33 subjects, 2 to 4 years old at first testing. Four tasks were used: one to assess semantic organization (the acquisition of the…
