Linguistic processing by the left and right cerebral hemispheres was investigated in 10 adult male stutters and 10 matched nonstutterers. Subjects performed a lexical decision task in which nonword and real-word stimuli were presented tachistoscopically to the right and left visual hemifields. Vocal and manual reaction times to real words were measured to assess hemispheric participation in processing linguistic information and to determine differences between response modes. The stuttering group exhibited a left visual field efficiency or right hemisphere preference for this task and were slower in both vocal and manual reaction times. Ramifications for hemispheric processing theories and laryngeal dysfunction hypotheses are discussed.
对10名成年男性口吃者和10名匹配的非口吃者的左右脑半球语言处理能力进行了研究。受试者进行了一项词汇判断任务，在该任务中，非单词和真实单词刺激通过速示器呈现给右半视野和左半视野。测量对真实单词的语音和手动反应时间，以评估半球参与语言信息处理的情况，并确定反应模式之间的差异。口吃组在这项任务中表现出左视野效率或右半球偏好，并且在语音和手动反应时间上都较慢。文中讨论了半球处理理论和喉部功能障碍假说的影响。
