We examined reciprocal associations between early maternal language use and children's language and cognitive development in seventy ethnically diverse, low-income families. Mother-child dyads were videotaped when children were aged 2;0 and 3;0. Video transcripts were analyzed for quantity and lexical diversity of maternal and child language. Child cognitive development was assessed at both ages and child receptive vocabulary was assessed at age 3;0. Maternal language related to children's lexical diversity at each age, and maternal language at age 2;0, was associated with children's receptive vocabulary and cognitive development at age 3;0. Furthermore, children's cognitive development at age 2;0 was associated with maternal language at age 3;0 controlling for maternal language at age 2;0, suggesting bi-directionality in mother-child associations. The quantity and diversity of the language children hear at home has developmental implications for children from low-income households. In addition, children's early cognitive skills further feed into their subsequent language experiences.
我们研究了 70 个种族多样、收入较低的家庭中，母亲早期语言使用与孩子语言和认知发展之间的相互关系。当孩子 2 岁零 0 个月和 3 岁零 0 个月大时，对母子二人进行了录像。对视频记录进行了分析，以确定母亲和孩子语言的数量和词汇多样性。在这两个年龄段都评估了儿童的认知发展，在 3 岁零 0 个月时评估了儿童的接受性词汇量。母亲的语言与每个年龄段孩子的词汇多样性有关，而 2 岁零 0 个月时母亲的语言与 3 岁零 0 个月时孩子的接受性词汇量和认知发展有关。此外，控制了 2 岁零 0 个月时的母亲语言，孩子 2 岁零 0 个月时的认知发展与 3 岁零 0 个月时的母亲语言有关，这表明母子关联具有双向性。孩子在家中听到的语言的数量和多样性对来自低收入家庭的孩子有发展意义。此外，孩子早期的认知技能进一步影响他们随后的语言体验。
