Sixteen adult, right-handed, moderate-to-severe atutterers (12 males, 4 females) and 20 nonstuttering controls (10 males, 10 females) were given a dichotic nonsense-syllable test to determine hemispheric lateralization for speech. Both male and female stutterers evidenced right-ear advantages in syllable identification similar in magnitude to those found for normals. These data confirm other reports of no difference in cerebral speech lateralization for stutterers and nonstutterers and, therefore, lend no support to theories that relate stuttering to abnormalities in cerebral lateralization.

16名成年右利手的中度至重度口吃者（12名男性，4名女性）和20名非口吃对照者（10名男性，10名女性）接受了一项双耳分听无意义音节测试，以确定言语的半球侧化情况。男性和女性口吃者在音节识别方面均表现出右耳优势，其程度与正常人相似。这些数据证实了其他关于口吃者和非口吃者大脑言语侧化无差异的报告，因此，不支持将口吃与大脑侧化异常相关联的理论。致谢。本研究是在作者们于康涅狄格大学斯托尔斯分校时进行的。非常感谢R.L. 韦伯斯特博士、行为研究所的工作人员以及康涅狄格大学心理学和语言学系的帮助。
