Maternal language characteristics associated with language-delayed children were examined. Two age groups of Down syndrome children were matched on mean length of utterance (MLU) with two groups of nonretarded, language-delayed children and two groups of "normal" children, mostly from middle-class families. Twenty-minute audio tapes were recorded for each dyad in the home during free play, and the first 10 minutes were transcribed and coded into functional types of maternal language. Mothers of nonretarded, language-delayed children used more language irrelevant to the interaction than did mothers of Down syndrome children, who, in turn, used more irrelevant language than did mothers of "normal" children. Mothers of nonretarded, language-delayed children focused less on their children's utterances than did other mothers and more on their physical behavior. Maternal language patterns appeared to be related more to language problems for nonretarded, language-delayed children than for Down syndrome children.
研究了与语言发育迟缓儿童相关的母亲语言特征。将两个年龄组的唐氏综合征儿童与两组发育正常但语言发育迟缓的儿童以及两组主要来自中产阶级家庭的“正常”儿童在平均语句长度（MLU）上进行匹配。在自由玩耍期间，为每个二元组在家中录制了20分钟的录音带，并对前10分钟进行转录，并编码为母亲语言的功能类型。发育正常但语言发育迟缓儿童的母亲比唐氏综合征儿童的母亲使用更多与互动无关的语言，而唐氏综合征儿童的母亲又比“正常”儿童的母亲使用更多无关语言。发育正常但语言发育迟缓儿童的母亲比其他母亲更少关注孩子的话语，而更多关注孩子的身体行为。母亲的语言模式似乎与发育正常但语言发育迟缓儿童的语言问题的相关性比与唐氏综合征儿童的语言问题的相关性更大。
