Cerebral lateralization in visual perception was investigated in 9 severe stuttering, 11 mild stuttering and 48 fluent speakers. The subjects were asked to identify words presented in the left or right visual field for 20 ms. Children responded by pointing to the exposed test word on a response card which contained four different words. Errors committed in the left and right visual fields were analyzed. The data showed a left hemisphere superiority in the processing of words in both the mild stutterers and the fluent speakers, but a right hemisphere advantage in the severe stutterers. The results suggest a close relationship between the severity of stuttering and functional brain organization.
对9名严重口吃者、11名轻度口吃者和48名流利说话者进行了视觉感知中的大脑偏侧化研究。要求受试者识别在左或右视野中呈现20毫秒的单词。儿童通过指向包含四个不同单词的反应卡上显示的测试单词来做出反应。分析了左、右视野中出现的错误。数据显示，轻度口吃者和流利说话者在单词处理上均表现出左半球优势，但严重口吃者则表现出右半球优势。结果表明口吃严重程度与大脑功能组织之间存在密切关系。
