Tests the proposition that family and personal factors, in combination with school characteristics, contribute to the academic progress of Quechua school children. Finds that family background and nutritional history are not as important in shaping educational progress as initially envisioned, but that duration of schooling is an important factor…

Explored the effects of differences between English-language and Chinese numerical systems for naming months and days on calendar calculations. Chinese and U.S. 8- and 10-year olds and undergraduates were asked to name a date coming before or after another given date. Found that Chinese speakers used calculations; English speakers recited names.…

Discussion of components of preverbal communicative competence in typically developing infants is related to development of children with severe physical impairment (SPI). Specifically, eye gaze, attention, and gesture are described as they relate to reciprocity, consistency, and predictability of infant-caregiver interactions. Intervention…

Discusses the importance of movement to mental and physical development, especially in young children's learning environments. Suggests that children naturally need to move in order to learn, and adults' efforts to entice children to sit still, pay attention, and be quiet often run contrary to this need. Proposes creating safe learning…

Reviews research relevant to children's understanding of pervasive, naturally occurring individual differences in thoughts and beliefs. Identifies developmental changes for each form of understanding: false belief, origins of knowledge, ambiguity, explicit judgments of knowledge, communication, and information seeking. Argues that considering…

An extended longitudinal study compared cognitive development in children adopted from Romania before 24 months and in United Kingdom adoptees with an additional sample of Romanian children adopted after 24 months. Findings indicated that there was considerable catch-up among late-placed Romanian children but they exhibited lower cognitive scores…

Describes the development and use of two computer simulations for investigating systems thinking and environmental problem-solving in children (n=92). Finds that older children outperformed younger children, who tended to exhibit magical thinking. Suggests that seemingly isomorphic environmental problems may not be interpreted as such by children.…

Two studies demonstrated dissociation between preschoolers' understanding of pictorial and mental representations. Results showed that false picture tasks were significantly easier than false belief tasks. There was no correlation between performance on the two. Children were trained on false belief, false picture, or number conservation tasks;…

Four studies examined developmental differences in the representation of basic-subordinate inclusion relationships in three-, five-, and seven-year olds and undergraduates. Found that even three-year olds showed rudimentary knowledge of the asymmetry of inclusion. There was a marked developmental gap between producing subordinate category names…

Explored how mothers convey information about category structure during naturalistic interactions. Videotaped reading-aloud sessions between mothers and toddlers; coded their interactions for explicit and implicit discussion of animal and artifact categories. Found that mothers provided a rich array of information beyond simple labeling routines,…

Compared kindergartners', third graders', and undergraduates' understanding and attribution of randomness. Found that kindergartners' interpretations were deterministic or outside the determinancy-indeterminancy frame. Most third graders had some grasp of randomness; their interpretations were less dominated by false attribution of determinism…

Presents an example of how a teacher can incorporate "play" into the music classroom. Describes play in general, discusses musical play, and considers the benefits of play for children. Addresses the teacher's role and how teachers can enter into children's play. (CMK)

Examines the ability of young and older adults with mild to moderate mental retardation to produce complex sentences in naturalistic conversation. The complex sentences produced were coded into subcategories of complementation, relativization, or coordination and then analyzed. No significant differences were observed between the two age groups.…

Comparison of 825 first-generation college students and 1,860 traditional college students in 23 diverse institutions after completion of 1 year found first-generation students differed from others in both entering characteristics and college experiences. Although traditional students made greater net gains in reading, the groups gained similarly…

Two cause indicator models were formulated to link items of the Home Observation for Measurement of the Environment--Short Form to the Peabody Picture Vocabulary Test--Revised. These models were tested with data from the National Longitudinal Survey of Youth (506 and 345 children), and a final model was developed. (SLD)
