Samples of conversational language were elicited with a standardized interview protocol from 24 children, aged 2:6 to 7:8, half with specific language impairment (SLI), half with normally developing language (LN), matched for language level. Samples were analyzed to determine whether there were associations between adult questioning and children's use of ellipsis. For the SLI children, but not the LN children, increased proportions of questions were significantly correlated to increased proportions of ellipsis. This finding has implications for the use of MLU measures in clinical and research practice.
通过标准化访谈协议，从24名年龄在2岁6个月至7岁8个月之间的儿童中收集了对话语言样本，其中一半患有特定语言障碍（SLI），另一半语言发育正常（LN），两组在语言水平上相匹配。对样本进行分析，以确定成人提问与儿童省略语使用之间是否存在关联。对于患有特定语言障碍的儿童，而非语言发育正常的儿童，问题比例的增加与省略语比例的增加显著相关。这一发现对临床和研究实践中平均长度词（MLU）测量方法的使用具有启示意义。
