Two left-handed siblings with developmental stuttering are comprehensively described. The methods of study included speech and language evaluation, neurological and neuropsychological examinations, dichotic listening, auditory evoked responses, electroencephalogram, and CT scan asymmetry measurements. The data from each sibling showed evidence of anomalous cerebral dominance on many of the variables investigated. The CT scan measurements showed atypical asymmetries, especially in the occipital regions. These findings support the theory that stuttering may be related to anomalous cerebral dominance, both on functional as well as structural bases. Implications of anomalous dominance and the resultant effect of hemispheric rivalry on speech fluency are discussed.
全面描述了两名患有发育性口吃的左利手兄弟姐妹。研究方法包括言语和语言评估、神经学和神经心理学检查、双耳分听、听觉诱发反应、脑电图以及CT扫描不对称测量。来自每个兄弟姐妹的数据显示，在许多研究变量上都有大脑优势异常的证据。CT扫描测量显示出非典型的不对称，尤其是在枕叶区域。这些发现支持了口吃可能在功能和结构基础上都与大脑优势异常有关的理论。讨论了优势异常及其对半球竞争对言语流畅性的影响。
