Although prior research has independently linked vocabulary development with toddlers' media usage, parental mental state talk (MST), and parent-child conversational turn-taking (CTT), these variables have not been investigated within the same study. In this study, we focus on associations between these variables and 2-year-old's (N = 87) vocabulary. Child vocabulary and digital media use were measured through online questionnaires. We took a multimethod approach to measure parents' child-directed talk. First, we used a home sound environment recording (Language ENvironment Analysis technology) to estimate parents' talk (CTT). Second, parents narrated a picture book, the Frog story, to assess the parent's MST. There was a negative association between how much children watched video content and their vocabulary. However, parents reported that they frequently co-viewed and engaged with the child and media. The negative association first displayed between the amount of video content viewed and the child's developing vocabulary was fully mediated by the parents' qualitative and quantitative talk as measured by MST and CCT, respectively. We propose that the parent relative level of MST and CTT also occurs when parents engage with the child during media use.
尽管先前的研究已经独立地将词汇发展与幼儿的媒体使用、父母的心理状态谈话（MST）和亲子对话轮次（CTT）联系起来，但这些变量在同一研究中尚未得到调查。在这项研究中，我们专注于这些变量与 2 岁儿童词汇量之间的关联。儿童词汇量和数字媒体使用通过在线问卷进行测量。我们采用了一种多方法的方法来衡量父母对孩子的谈话。首先，我们使用家庭声音环境记录（语言环境分析技术）来估计父母的谈话（CTT）。其次，父母讲述了一本图画书，青蛙的故事，以评估父母的 MST。孩子观看视频内容的多少与他们的词汇量呈负相关。然而，父母报告说，他们经常与孩子一起观看和参与媒体。孩子观看视频内容的多少与词汇量的发展之间的负相关首先由 MST 和 CCT 分别测量的父母的定性和定量谈话来完全调节。我们提出，当父母在使用媒体时与孩子互动时，父母的相对 MST 和 CTT 水平也会出现。
