This study compares parental pause and utterance duration in conversations with Swedish speaking children at age 1;6 who have either a large, typical, or small expressive vocabulary, as measured by the Swedish version of the McArthur-Bates CDI. The adjustments that parents do when they speak to children are similar across all three vocabulary groups; they use longer utterances than when speaking to adults, and respond faster to children than they do to other adults. However, overall pause duration varies with the vocabulary size of the children, and as a result durational aspects of the language environment to which the children are exposed differ between groups. Parents of children in the large vocabulary size group respond faster to child utterances than do parents of children in the typical vocabulary size group, who in turn respond faster to child utterances than do parents of children in the small vocabulary size group.
本研究比较了与瑞典语为母语、年龄为1岁6个月且通过瑞典版麦克阿瑟-贝茨沟通发展指标（CDI）测得具有大、中、小表达性词汇量的儿童对话时父母的停顿时间和话语时长。在与这三组词汇量不同的儿童对话时，父母所做的调整是相似的；他们与儿童说话时的话语比与成人说话时更长，并且对儿童的回应比对其他成人的回应更快。然而，总体停顿时间随儿童的词汇量大小而变化，因此不同组的儿童所接触的语言环境在时长方面存在差异。大词汇量组儿童的父母对儿童话语的回应比典型词汇量组儿童的父母更快，而典型词汇量组儿童的父母对儿童话语的回应又比小词汇量组儿童的父母更快。
