Six language-impaired children, each having a mean length of utterance (MLU) greater than 3.0, were observed in dyadic interactions with (1) normal-language children of similar chronological ages and (2) normal-language children who were younger but exhibited similar MLUs. Eight measures analyzing overall sentence complexity, sentence form, and features of discourse were used to compare the subjects' linguistic behaviors in the two conditions. Across conditions, the subjects made changes in their speech that were consistent with the speech style modifications made by normal-language children observed in earlier interaction studies. Lower Mean Pre-Verb Length, a greater degree of conversational assertiveness, and a higher frequency of Internal-State Questions were characteristic of the subjects in the MLU-matched condition as compared to the age-matched condition. Diagnostic and therapy considerations are discussed in view of these findings.
研究观察了六个语言障碍儿童，他们每人的平均语句长度（MLU）都大于3.0，这些儿童与（1）年龄相仿的正常语言儿童以及（2）年龄较小但MLU与之相似的正常语言儿童进行了二元互动。采用八项分析整体句子复杂性、句子形式和话语特征的指标，来比较受试者在两种情境下的语言行为。在不同情境中，受试者的言语变化与早期互动研究中观察到的正常语言儿童的言语风格变化一致。与年龄匹配情境相比，在MLU匹配情境下，受试者的平均动词前长度更低、对话中的 assertiveness 程度更高，以及内部状态问题的出现频率更高。鉴于这些发现，本文讨论了诊断和治疗方面的考量。 （注：“assertiveness”直译为“坚定自信”，结合语境这里意译为“ assertiveness程度更高”较合适，但原文表述有些模糊，翻译可能不是特别精准）
