Responsive parental communication during an infant's first year has been positively associated with later language outcomes. This study explores responsivity in mother-infant communication by modeling how change in guiding language between 7 and 11 months influences toddler vocabulary development. In a group of 32 mother-child dyads, change in early maternal guiding language positively predicted child language outcomes measured at 18 and 24 months. In contrast, a number of other linguistic variables - including total utterances and non-guiding language - did not correlate with toddler vocabulary development, suggesting a critical role of responsive change in infant-directed communication. We further assessed whether maternal affect during early communication influenced toddler vocabulary outcomes, finding that dominant affect during early mother-infant communications correlated to lower child language outcomes. These findings provide evidence that responsive parenting should not only be assessed longitudinally, but unique contributions of language and affect should also be concurrently considered in future study.
婴儿出生后第一年父母的积极回应式沟通与后期语言发展结果呈正相关。本研究通过模拟7至11个月大时引导性语言的变化如何影响幼儿词汇发展，来探索母婴沟通中的回应性。在一组32对母婴二元组中，早期母亲引导性语言的变化积极预测了18个月和24个月时测量的儿童语言发展结果。相比之下，许多其他语言变量——包括总话语量和非引导性语言——与幼儿词汇发展没有相关性，这表明回应式变化在婴儿导向型沟通中起着关键作用。我们进一步评估了早期沟通中母亲的情感是否会影响幼儿词汇发展结果，发现早期母婴沟通中的主导情感与较低的儿童语言发展结果相关。这些发现提供了证据，表明不仅应纵向评估回应式育儿，而且在未来研究中还应同时考虑语言和情感的独特作用。
