天生失明的人习惯性地在没有视觉线索的情况下体验语言话语,并在句子理解过程中激活“视觉”皮层。盲人在句子处理任务中表现出上级的表现吗?先天性失明(n=25)和年龄和教育匹配的视力(n=52)的参与者回答是/否谁做了什么给谁的问题,其中一些包含语法复杂性操纵(长距离运动依赖或花园路径)。短期记忆是用向前和向后的字母跨度来测量的。一组控制任务包括两个快速数学任务和词汇和阅读任务,来自伍德考克约翰逊三世。盲人组在句子理解任务中的表现优于视力正常的人,特别是在花园小径句子和短期记忆广度任务中,但在控制任务中的表现与视力正常的人相似。句子理解性能与跨度性能不相关,这表明独立的增强。
People born blind habitually experience linguistic utterances in the absence of visual cues and activate “visual” cortices during sentence comprehension. Do blind individuals show superior performance on sentence processing tasks? Congenitally blind (n=25) and age and education matched sighted (n=52) participants answered yes/no who-did-what-to-whom questions for auditorily-presented sentences, some of which contained a grammatical complexity manipulation (long-distance movement dependency or garden path). Short-term memory was measured with a forward and backward letter-spans. A battery of control tasks included two speeded math tasks and vocabulary and reading tasks from Woodcock Johnson III. The blind group outperformed the sighted on the sentence comprehension task, particularly for garden-path sentences, and on short-term memory span tasks, but performed similar to the sighted on control tasks. Sentence comprehension performance was not correlated with span performance, suggesting independent enhancements.
