This study examined the extent to which executive function (EF) mediated associations of socioeconomic status (SES) and home-environment quality with academic readiness (math, letter and word identification, and knowledge of story-and-print concepts). Forty-nine 54–66-month old children and their mothers participated in a home observation and laboratory visit. Hierarchical regression analyses revealed the EF mediated associations between SES and math outcomes. These findings were observed after controlling for child verbal abilities. Implications for the role of verbal ability in EF, the developmental context in predicting EF, and the influence of EF on academic readiness are discussed. 相似文献

Children's lead and pesticide exposures are used as examples to examine social disparities in exposure reduction efforts as well as environmental policies impacting children in poverty and minority children. The review also presents an estimate of the effect of social disparities in lead exposure on standardized test performance. Because including measures of pollutants with potential behavioral effects can alter the observed effects of race/ethnicity, income, and other variables, suggestions are made for including measures of pollutants in longitudinal studies and studies of multiple and cumulative risk. Continued basic research on developmental correlates and effects of pollution exposure, participatory action-research with at-risk and underrepresented populations, and contributions to public awareness and education are important leadership areas for developmental researchers. 相似文献
