Researchers agree that early literacy activities, like book sharing and parent-child play, are important for stimulating language development. We hypothesize that book sharing is most powerful because it elicits more interactive talk in young children than other activities. Parents of 43 infants (9–18 months) made two daylong audio recordings using the LENA system. We compared a typical day, with spontaneous occurring activities, with an instructed day when caregivers were prompted to do book reading and toy play. Book sharing resulted in a combination of more parent talk, child talk, and interactions than other language activities. Research context did not influence outcomes: no differences were found in language use between the spontaneous and the instructed activities. Overall it seems clear that even with infants shared reading is a strong unique stimulator of language use from parent and child.

共享阅读对成人-儿童语言互动的独特贡献

研究人员一致认为，早期识字活动，如书籍分享和亲子游戏，对于刺激语言发展很重要。我们假设书籍分享最有效，因为它比其他活动更能引发幼儿的互动谈话。43 名婴儿（9-18 个月）的父母使用 LENA 系统制作了为期两天的录音。我们将自发活动的典型一天与照料者被提示阅读和玩玩具的指示日进行了比较。与其他语言活动相比，书籍分享导致更多的家长谈话、孩子谈话和互动。研究背景不影响结果：自发活动和指导活动之间的语言使用没有差异。
