摘要
有关早期语言输入和社会经济地位的研究通常依赖于小样本的相关性。本文利用 "婴儿最初几年"（Baby's First Years）的数据，评估了每月无条件现金转移对美国低收入母亲及其 1 岁幼儿（N = 563；48% 为女孩；2019-2020 年）的大量种族多元化样本中的儿童引导性言语和儿童发声的因果影响。每月无条件的现金转移并未影响母亲在10分钟的家庭游戏过程中引导儿童说话的能力（效应大小从-.08到.02不等），尽管在该样本中存在很大差异。未来的工作将评估持续现金转移对儿童语言输入和语言发展的影响。
Child-directed speech in a large sample of U.S. mothers with low income.
Research on early language input and socioeconomic status typically relies on correlations in small convenience samples. Using data from Baby's First Years, this paper assesses the causal impact of monthly, unconditional cash transfers on child-directed speech and child vocalizations among a large, racially diverse sample of low-income U.S. mothers and their 1-year-olds (N = 563; 48% girls; 2019-2020). The monthly, unconditional cash transfers did not impact mothers' child-directed speech during a 10-min at-home play session (effect sizes range from -.08 to .02), though there was wide variability within this sample. Future work will assess the impact of the continued cash transfer on children's language input and development over time.
