摘　　要：阅读障碍语音缺陷是阅读障碍的关键原因之一。脑科学研究发现,拼音文字系统中阅读障碍者在语音加工的神经机制上存在缺陷,相关脑区包括颞—顶—枕联合区和额下回;而汉语阅读障碍者语音加工时,激活的脑区和拼音文字系统阅读障碍者激活的脑区不同,涉及左额中回和右脑一些皮层。基于此,提出了相应的阅读教学建议。Phonological deficit is one of the key reasons in dyslexia. The research studies on the brain science indicated that the dyslexia in alphabetic writing systems had phonological processing deficit in the neural mechanism,including the parieto-temporal-occipital region and inferior frontal cortex. However, the cerebral activation pattern of the phonological processing is different from the Chinese dyslexia, which involved the left middle frontal gyms and some cortical regions in right hemisphere. Based on thi, the counter-measures of the teaching were proposed.
