研究人员记录了61名年龄在18岁至26岁之间的讲日语的单身女性大声朗读图画书给一个年幼的孩子听，以及与另一名讲日语的女性交谈。当他们的话语之间的两个设置的韵律特征进行声学比较，平均音高和音高偏移表现出显着增加时，与孩子互动的61名妇女中的17。在其余44例受试者中，36例受试者的这些参数均未显示此类变化。这种个体差异性与受试者对图画书的喜好、以前的阅读或被阅读的经历、或照看婴儿的经历无关。唯一可以解释这个结果的变量是，受试者是否有一个或多个兄弟姐妹或独生子女。如果他们是独生子女，韵律修改明显不太可能发生。
Sixty-one single Japanese-speaking women between the ages of 18 and 26 years were recorded as they read aloud picture books to a young child and as they conversed with another Japanese-speaking woman. When their utterances were acoustically compared between the two settings with regard to prosodic features, both the average pitch and pitch excursions exhibited a significant increase when interacting with the child in 17 of the 61 women. In 36 of the remaining 44 subjects, neither of these parameters showed such changes. This individual variability was not related to the subjects' liking for picture books, previous experience with reading or being read them, or with baby-sitting. The only variable that could explain the results was whether the subjects had grown up with one or more siblings or as only children. If they were only children, the prosodic modification was significantly less likely to occur.
