We examined the relative contribution of auditory processing abilities (tone perception and speech perception in noise) after controlling for short-term memory capacity and vocabulary, to narrative language comprehension in children with developmental language disorder. Two hundred and sixteen children with developmental language disorder, ages 6 to 9 years ( = 7; 6), were administered multiple measures. The dependent variable was children's score on the narrative comprehension scale of the . Predictors were auditory processing abilities, phonological short-term memory capacity, and language (vocabulary) factors, with age, speech perception in quiet, and non-verbal IQ as covariates. Results showed that narrative comprehension was positively correlated with the majority of the predictors. Regression analysis suggested that speech perception in noise contributed uniquely to narrative comprehension in children with developmental language disorder, over and above all other predictors; however, tone perception tasks failed to explain unique variance. The relative importance of speech perception in noise over tone-perception measures for language comprehension reinforces the need for the assessment and management of listening in noise deficits and makes a compelling case for the functional implications of complex listening situations for children with developmental language disorder.
我们研究了在控制短期记忆容量和词汇量之后，听觉处理能力（音调感知和噪声中的言语感知）对发育性语言障碍儿童叙事语言理解的相对贡献。对216名6至9岁（平均年龄 = 7岁6个月）的发育性语言障碍儿童进行了多项测量。因变量是儿童在《……》叙事理解量表上的得分。预测因素包括听觉处理能力、语音短期记忆容量和语言（词汇）因素，将年龄、安静环境下的言语感知和非言语智商作为协变量。结果表明，叙事理解与大多数预测因素呈正相关。回归分析表明，在所有其他预测因素之外，噪声中的言语感知对发育性语言障碍儿童的叙事理解有独特贡献；然而，音调感知任务未能解释独特的方差。噪声中的言语感知相对于音调感知测量对语言理解的相对重要性，强化了评估和管理噪声中听力缺陷的必要性，并有力地说明了复杂听力情境对发育性语言障碍儿童的功能影响。
