Children acquire language embedded within the rich social context of interaction. This paper reports on a longitudinal study investigating the developmental relationship between conversational turn-taking and vocabulary growth in English-acquiring children (N = 122) followed between 9 and 24 months. Daylong audio recordings obtained every 3 months provided several indices of the language environment, including the number of adult words children heard in their environment and their number of conversational turns. Vocabulary was measured independently via parental report. Growth curve analyses revealed a bidirectional relationship between conversational turns and vocabulary growth, controlling for the amount of words in children's environments. The results are consistent with theoretical approaches that identify social interaction as a core component of early language acquisition.
儿童在丰富的互动社交环境中习得语言。本文报告了一项纵向研究，该研究调查了在 9 至 24 个月期间，英语习得儿童（N=122）的会话轮流和词汇增长之间的发展关系。每隔 3 个月进行一次全天录音，提供了语言环境的多个指标，包括儿童在环境中听到的成人单词数量和他们的对话轮次数量。词汇量通过父母报告进行独立测量。增长曲线分析显示，在控制儿童所处环境中单词数量的情况下，会话轮次和词汇增长之间存在双向关系。这些结果与将社会互动确定为早期语言习得核心组成部分的理论方法一致。
