There is robust evidence that infants' gestures and vocalisations and caregivers' contingent responses predict later child vocabulary. Recent studies suggest that dyadic combinations of infants' behaviors and caregivers' responses are more robust predictors of children's vocabularies than these behaviors separately. Previous studies have not yet systematically compared different types of dyadic combinations. This study aimed to compare the predictive value of (a) frequencies of infants' behaviors (vocalisations, points, and shows + gives) regardless of caregivers' responses, (b) frequencies of infants' behaviors that elicited verbal responses, (c) frequencies of infants' behaviors that elicited multimodal responses, and (d) frequencies of infants' behaviors that did not elicit any responses from caregivers. We examined 114 caregiver-infant dyads at 9-11 months and children's concurrent and longitudinal vocabulary outcomes at 2-4 years. We found that infants' points elicited a large proportion of verbal responses from caregivers which were related to children's later receptive vocabularies. We also found that only shows + gives that elicited caregivers' responses related to infants' concurrent gesture repertoires. In contrast, infants' behaviors that did not elicit responses negatively related to child vocabulary. The results highlight the importance of examining dyadic combinations of infants' behaviors and caregivers' responses during interactions when examining relations to children's vocabulary development.
有充分的证据表明，婴儿的手势、发声以及照顾者的即时反应能够预测儿童日后的词汇量。近期研究表明，相较于单独的婴儿行为或照顾者反应，婴儿行为与照顾者反应的二元组合是儿童词汇量更有力的预测指标。以往研究尚未系统地比较不同类型的二元组合。本研究旨在比较以下几种情况的预测价值：(a) 不考虑照顾者反应时婴儿行为（发声、指物以及展示 + 给予）的频率；(b) 引发言语反应的婴儿行为的频率；(c) 引发多模态反应的婴儿行为的频率；(d) 未引发照顾者任何反应的婴儿行为的频率。我们对114对9至11个月大的照顾者 - 婴儿二元组进行了研究，并考察了儿童在2至4岁时的同步和纵向词汇量结果。我们发现，婴儿的指物行为引发了照顾者很大比例的言语反应，这些反应与儿童日后的接受性词汇量相关。我们还发现，只有引发照顾者反应的展示 + 给予行为与婴儿当时的手势技能相关。相比之下，未引发反应的婴儿行为与儿童词汇量呈负相关。研究结果凸显了在考察与儿童词汇发展的关系时，研究互动过程中婴儿行为与照顾者反应的二元组合的重要性。
