We compared mothers reading books to six-month-old infants or playing with toys and measured whether the maternal language input influenced the children's spoken vocabulary at 18 months of age.
This Taiwanese study recruited 46 dyads and video recorded them while the mothers read books to their infants and played with them with toys at 6 months of age. The mothers' lexical diversity, which is the ratio of different unique words to the total number of words, was measured. We then assessed the children's spoken vocabulary at 18 months.
The mother used more diverse vocabulary and a higher number of words when they were reading books than playing with toys with their children (p = 0.001). Maternal lexical diversity at 6 months of age accounted for 14.4% of the unique variance in the number of different words used by the child at 18 months. We believe that this is a novel finding.
Mothers used wider vocabulary and talked to their infants more during book reading than when they played with toys. Diverse maternal vocabulary at 6 months of age positively influenced the number of different words their children used at 18 months of age.
我们比较了母亲给 6 个月大的婴儿读书或与他们玩玩具时的语言输入，并测量了母亲的语言输入是否会影响孩子在 18 个月时的口语词汇量。
这项来自中国台湾的研究招募了 46 对母婴，并在母亲 6 个月大时分别给婴儿读书和用玩具与他们玩耍时进行视频记录。我们测量了母亲词汇多样性，即不同独特词汇与总词汇数的比率。然后，我们在孩子 18 个月时评估了他们的口语词汇量。
与玩玩具相比，母亲在给孩子读书时使用的词汇更加多样，词汇量也更高（p=0.001）。母亲 6 个月时的词汇多样性解释了孩子 18 个月时使用的不同词汇数量的 14.4%的独特差异。我们认为这是一个新的发现。
母亲在给孩子读书时比玩玩具时使用的词汇更广泛，与孩子的对话也更多。母亲 6 个月时的词汇多样性积极影响了孩子 18 个月时使用的不同词汇数量。
