The guidelines published by the National Association for the Education of Young Children on the use of developmentally appropriate practices (DAP) have, over the last two decades, had an important influence on young children's educational experiences. The efficacy of these guidelines for changing children's outcomes has been examined by only a…

We examined theoretical issues concerning the development of reading fluency and language proficiency in 390 English Language Learners (ELLs,) and 149 monolingual, English-as-a-first language (EL1) students. The extent to which performance on these constructs in Grade 5 (i.e., concurrent predictors) contributes to reading comprehension in the…

The purposes of this study were to (a) examine the developmental patterns in pseudoword reading and oral reading fluency in Spanish and English for Spanish-speaking English learners (ELs) in grades 1-3, and (b) investigate whether initial status and growth rates in reading fluency in Spanish and English, significantly predicted reading…

In Experiment 1, Japanese children (4-, 5-, 7-, and 10-year-olds (n = 78)) and adults (n = 36), answered questions about the possibility of psychogenic bodily reactions, i.e., bodily outcomes with origins in the mind. The 4- and 5-year-old preschoolers typically denied that bodily conditions could originate in mental states. Developmentally,…

This study investigated the structure and development of processes involved in "g." One hundred and forty children, about equally drawn among primary school grades 1-6 were examined by four types of Stroop-like speeded tasks addressed to processes of increasing complexity (i.e., speed of processing, perceptual discrimination, perceptual control,…

Researchers and policymakers are increasingly interested in the impact of afterschool programs on youth development. Even though numerous studies have investigated the impact of afterschool participation on academic outcomes, there is limited research on the differential impact of afterschool programs based on students' participation rate. This…

This study had two aims: first, to investigate how emerging reading and spelling are interlinked when children move up from preschool to primary school and, second, to examine the antecedents of these skills. The study is part of the Jyvaskyla Entrance into Primary School Study in which 196 children 5 to 6 years of age were followed up every half…

The authors examined developmental and individual differences in pure numerical estimation, the type of estimation that depends solely on knowledge of numbers. Children between kindergarten and 4th grade were asked to solve 4 types of numerical estimation problems: computational, numerosity, measurement, and number line. In Experiment 1,…

The purpose of this study was to investigate predictors of early writing for low-income, urban students. Drawing on research and theory characterizing literacy development as a complex, integrative process, the author analyzed growth in the descriptive writing of students in Grades 1-3. The participants were 309 low-income children enrolled in 16…
