The performance of a group of stutters (N = 14) and a group of nonstutterers (N = 14) was compared on the Synthetic Sentence Identification Test (Speaks and Jerger, 1965). The test is designed to assess central auditory function. It was hypothesized that because of subtle neurologically based differences in perceptual processing, the performance of the two groups would differ significantly on one or more of the subtests. An analysis of variance revealed that the performance of the stuttering group was significantly poorer (0.01 level of confidence) than that of the nonstutteres on the Ipsilateral Competing Message Subtest. The results of the investigation were compatible with other studies that suggest a neurological dysfunction within the central auditory apparatus as at least one of the underlying causes of disfluency. It was concluded that further investigations of the central auditory processes in stutterers are warranted to make a more definitive statement about the etiology of stuttering.
在合成句子识别测试（Speaks和Jerger，1965年）中，对一组口吃者（N = 14）和一组非口吃者（N = 14）的表现进行了比较。该测试旨在评估中枢听觉功能。据推测，由于在感知处理方面存在基于神经学的细微差异，两组在一个或多个子测试中的表现会有显著差异。方差分析显示，在同侧竞争信息子测试中，口吃组的表现明显比非口吃组差（置信水平为0.01）。该调查结果与其他研究一致，这些研究表明中枢听觉器官内的神经功能障碍至少是言语不流畅的潜在原因之一。得出的结论是，有必要对口吃者的中枢听觉过程进行进一步研究，以便对口吃的病因作出更明确的说明。
