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.

在大量美国低收入母亲样本中采用儿童导向的言语


关于早期语言输入和社会经济地位的研究通常依赖于小便利样本中的相关性。本文使用婴儿第一年的数据，评估了每月无条件现金转移支付对大量低收入美国母亲及其 1 岁儿童（N = 563;48% 女孩;2019-2020 年）种族多元化样本中面向儿童的言语和儿童发声的因果影响。每月的无条件现金转移不会影响母亲在 10 分钟的家庭游戏期间以儿童为导向的言语（效应大小范围从 -.08 到 .02），尽管该样本内存在很大差异。未来的工作将评估持续现金转移支付对儿童语言输入和发展的影响。
