ABSTRACT

The current study examined how mothers’ production of four types of internal state words at multiple ages across the second year in a free play context was related to their infants’ acquisition of those words. Twenty-nine mother-infant dyads were videotaped for 18 minutes during free play when infants were 13 and 17 months old. Mothers’ total and number of different internal state words—subcategorized as disposition (like, happy), perception (see, hear) volition (want, need), and cognition (think, know) —were obtained. Infants’ total and internal state subcategory vocabularies were measured with the MacArthur-Bates Communicative Development Inventory at 13, 17, and 21 months. Maternal internal state speech at 13 months was related to infants’ overall concurrent receptive lexicons, while mothers’ volition words at 13 months predicted infants’ receptive total and internal state vocabularies at 17 months. Mothers’ different perception words at 17 months were linked to infants’ concurrent perception lexicons. Furthermore, mothers’ different disposition words at 17 months predicted children’s expressive disposition vocabularies at 21 months. These findings illuminate the value of examining subcategories of mothers’ internal state speech in free play and reveal a shift over time from general to specific relations between mothers’ and infants’ internal state language.

摘要

当前的研究调查了母亲在第二年在自由玩耍的情况下，在多个年龄段产生的四种内部状态词与婴儿获取这些词的关系。在免费游戏期间（年龄分别为13和17个月大的婴儿），对29个母婴双胞胎进行了18分钟的录像。获得了母亲不同的内在状态单词的总数和数量，这些单词分为：性格（喜欢，快乐），知觉（见，听），意志（想要，需要）和认知（想知道）。婴儿的全部和内部状态子类别的词汇是在13、17和21个月时使用MacArthur-Bates交流发展清单进行测量的。孕妇在13个月时的内部状态演讲与婴儿的整体并发接受词典有关，母亲在13个月时的自愿言语预测了婴儿在17个月时的总体接受能力和内部状态词汇。母亲在17个月时的不同知觉词与婴儿的并发知觉词典相关。此外，母亲在17个月时使用的不同性格词汇预测了21个月时孩子的表达性词汇。这些发现阐明了在自由活动中检查母亲的内部状态语言子类别的价值，并揭示了母亲和婴儿内部状态语言之间从一般关系到特定关系的时间变化。母亲在17个月时使用的不同性格词汇预测了21个月时孩子的表达性词汇。这些发现阐明了在自由活动中检查母亲的内部状态语言子类别的价值，并揭示了母亲和婴儿内部状态语言之间从一般关系到特定关系的时间变化。母亲在17个月时使用的不同性格词汇预测了21个月时孩子的表达性词汇。这些发现阐明了在自由活动中检查母亲的内部状态语言子类别的价值，并揭示了随着时间的推移，母亲和婴儿的内部状态语言之间从一般关系到特定关系的转变。
