The present study was an attempt to investigate further the issues pertaining to cerebral organization for visual language processing in the stuttering population. Employing a lexical decision task, vocal reaction times were obtained for a group of 14 stutterers to unilateral, tachistoscopically presented concrete and abstract words. Results of an analysis of variance showed that a significant interaction occurred between visual fields and stimuli. Posthoc tests showed that the right hemisphere was superior for analyzing the concrete words while the left hemisphere was responsible for processing the abstract items. Compared to past data from normal subjects, these findings were interpreted as suggesting that some form of linguistic competition may exist between the two hemispheres, possibly reflecting a disturbance in functional localization in the stuttering population.
本研究旨在进一步探讨口吃人群中视觉语言处理的大脑组织相关问题。采用词汇判断任务，对14名口吃者组成的小组在单侧、速视呈现具体和抽象单词时的语音反应时间进行了测定。方差分析结果显示，视野和刺激之间存在显著交互作用。事后检验表明，右半球在分析具体单词方面更具优势，而左半球负责处理抽象词汇。与正常受试者过去的数据相比，这些发现被解释为表明两个半球之间可能存在某种形式的语言竞争，这可能反映了口吃人群功能定位的紊乱。
