A large body of research shows connections between infants' and toddlers' home language input and a wide range of receptive and expressive early language skills. Some facets of caretaker input and early language skills are associated with socioeconomic status (SES), though not all. Given the complexity of language learning, language use, and its many pathways of connection to SES, testing causal links between these dimensions is difficult at best. Interventions aimed at changing parent language use have seen mixed success, in part because "language infusions" generally fail to target underlying challenges facing underresourced families, and perhaps because parent language is the wrong target. System-level interventions such as paid parental leave and expansion and enrichment of childcare and early education options hold greater promise for improving families' lives, with positive repercussions for a broad range of family and child outcomes, including linguistic ones.
大量研究表明,婴幼儿的家庭语言输入与广泛的早期语言接受和表达技能之间存在联系。照顾者的语言输入和早期语言技能的某些方面与社会经济地位(SES)相关,但并非全部。鉴于语言学习、语言使用的复杂性及其与社会经济地位的众多联系途径,充其量只能很难测试这些维度之间的因果关系。旨在改变家长语言使用的干预措施取得了喜忧参半的成果,部分原因是“语言注入”通常未能针对资源不足家庭面临的潜在挑战,也可能是因为家长语言并非正确的干预目标。诸如带薪育儿假以及扩大和丰富儿童保育与早期教育选择等系统层面的干预措施,对于改善家庭生活更具前景,对包括语言方面在内的一系列家庭和儿童成果会产生积极影响。
