One of the prerequisites for normal language development is a highly sensitive auditory perception. An auditory perception deficit is therefore likely to affect the normal course of language acquisition. To test this hypothesis, we studied the BAEPs in 25 preschool boys with an expressive developmental language disorder and 12 boys with a history of stuttering. These children had no hearing disorders. Comparisons with the control group (49 neurologically healthy male subjects with normal hearing) revealed a statistically significant delay of waves III, IV and V in the language impaired subjects, whereas no significant differences were detected in the group of stutterers. Our findings suggest that a delayed or altered conduction of acoustic stimuli is important to the pathogenesis of developmental language disorders.
正常语言发展的前提条件之一是高度敏感的听觉感知。因此，听觉感知缺陷很可能会影响语言习得的正常进程。为了验证这一假设，我们研究了25名患有表达性发育性语言障碍的学龄前男孩和12名有口吃病史的男孩的脑干听觉诱发电位（BAEP）。这些儿童没有听力障碍。与对照组（49名听力正常、神经系统健康的男性受试者）相比，发现语言受损受试者的III、IV和V波在统计学上有显著延迟，而口吃组未检测到显著差异。我们的研究结果表明，听觉刺激传导延迟或改变对发育性语言障碍的发病机制很重要。
