Abstract: Developmental dyslexia is a specific impairment in the acquisition of reading skills. The causes leading to this impairment have always been a core issue in this field. More and more research have revealed there is a strong relationship between visual magnocellular-dorsal pathway function and reading related skills. The magnocellular-dorsal pathway deficit might be one of the main reasons resulting in dyslexia. A number of studies also find the magnocellular-dorsal pathway deficit in Chinese children with developmental dyslexia. We review the studies about the function of visual magnocellular-dorsal pathway in Chinese children with dyslexia in the recent years, and propose some critical issues which are needed to be addressed in the future.

Key words: developmental dyslexia, Chinese children, vision, magnocellular, dorsal stream

摘要: 发展性阅读障碍是一种在获得阅读技能方面的特殊困难,其致病原因一直是该领域的核心问题。越来越多的研究表明视觉大细胞-背侧通路功能与阅读技能之间存在紧密联系。视觉大细胞-背侧通路缺陷可能是导致阅读障碍的主要原因之一。一些研究发现汉语阅读障碍儿童同样存在视觉大细胞-背侧通路缺陷。本文将回顾近些年汉语发展性阅读障碍儿童视觉大细胞-背侧通路功能的相关研究成果,并对该领域未来的发展方向做出展望。
