This study assesses the consequences of housing instability during the first 5 years of a child's life for a host of school readiness outcomes. Using data from the Fragile Families and Child Wellbeing Study (n = 2,810), this study examines the relation between multiple moves and children's language and literacy and behavior problems at…

Bronfenbrenner's (1979) ecological model proposes that events in higher order social ecosystems should influence human development through their impact on events in lower order social ecosystems. This proposition was tested with respect to ecological violence and the development of children's aggression via analyses of 3 waves of data (1 wave…

A crucial skill in scientific and everyday reasoning is the ability to interpret data. The present study examined how data features influence data interpretation. In Experiment 1, one hundred and thirty-three 9-year-olds, 12-year-olds, and college students (mean age = 20 years) were shown a series of data sets that varied in the number of…

It was concluded that drawing rules are essential and that adequate visual analysis is a necessary but not sufficient prerequisite to the production of accurate copies. (Author)

The present study, based on teachers' ratings of their 4- and 5-year-old students, examined the correspondence between quantity and sophistication of verbal output and the child's production of gross bodily activity and fine manipulative movements. (Authors)

Preschool, first-grade, and fifth-grade children served as Ss in 2 experiments designed to test the developmental hypothesis that memorizing and perceiving are functionally undifferentiated for the young child, with deliberate memorization only gradually emerging as a separate and distinctive form of cognitive encounter with external data.…

A Foster-Grandparent Program group received part-time mothering'' by elderly institutional aids for a period of up to more than 4 years. A control group resided in a similar institution which did not provide supplementary foster grandparent'' care. There was a significant difference in IQ in favor of the FGP children. (Author)

Ability to distinguish intention from accident and understanding of unconscious intention were examined in preschool, kindergarten, and third-grade-age children. (Author)

Suggests ways to use dynamic systems analysis to illuminate the pluralistic and multidimensional model described by Larivee, Normandeau, and Parent (2000). Issues discussed include the characteristics of developmental transitions, such as hysteresis; nature of growth processes, such as hierarchical development or predator-prey interactions; and…

Shares three ideas concerning how to evaluate the practical importance of developmental findings to make them more useful to policymakers: (1) statistical significance tests need to be accompanied by effect size estimates; (2) meta-analyses are helping in using all existing data when examining issues involved in policy debates; and (3) researchers…

Both 4- and 7-year-old children readily reformulated their initial messages when explicitly requested to do so by the listener, and both failed to reformulate when confronted only with nonverbal, facial expressions of listener noncomprehension. (Authors)

Suggests that recent social changes and trends make it imperative to include demographics of all kinds in research on child development. Proposes guidelines to help child development researchers procure demographic information from their study population. Provides specific questions that may help researchers devise demographic indicators, and…

Analyses revealed consistent support for the hypothesis that number conservation is developmentally prior to liquid quantity conservation. (Authors)

Comments on the ideas presented by Entwisle and Astone in this issue. Suggests that to produce sound measurements of children's socioeconomic background requires a substantial investment in coding, data collection, and management. Nevertheless, a standard set of racial-ethnic and socioeconomic variables, no matter how well measured, cannot serve…
