研究追踪 Early Head Start 儿童在新冠疫情期间及之后的语言发展
Beyond the shutdown: Tracking language growth in Early Head Start children before, during, and after COVID-19
依据摘要，一项发表于《Child Development》的研究追踪了 Early Head Start 项目中低收入家庭婴幼儿在新冠疫情前、疫情高峰及至 2025 年的语言环境与语言发展，样本为 2–43 月龄儿童 2,763 名。结果显示，疫情后课堂语言环境指标平均有所改善，但家长报告的语言技能出现下降，儿童发声增长也滞后。研究还考察了潜在调节因素，并讨论了对未来研究与实践的启示。
Understanding early language outcomes for low-income children in the wake of the COVID-19 pandemic is an important concern for researchers, policymakers, and educators. We examined language environments and language development among infants and toddlers in Early Head Start from pre-COVID, through the pandemic peak and beyond to 2025. Study children were aged 2–43 months ( N = 2,763; 47% girls; 42% Hispanic of any race; 46% Black or African American, non-Hispanic; 6% White, non-Hispanic; 4% multiracial or biracial, non-Hispanic; 3% other race or unspecified, non-Hispanic). On average, measures of children's classroom language environments improved postpandemic, but children experienced declines in parent-reported language skills and growth lags in child vocalizations in the pandemic's wake. We examine potential moderators and discuss implications for future research and practice.
