阅读障碍与视觉功能的研究进展

The advancement of researches on dyslexia and vision function

一百多年来对于阅读障碍的病因及发病机制,不同学者意见不一。目前,大多数学者认为:阅读障碍是由于人类早期对于视觉及语音信息的认知和加工能力的发育障碍所致,即以下两种神经行为学假说:语音加工缺陷假说;基本感知觉加工缺陷假说。同时患者还伴随一定程度的神经结构功能异常,主要表现在视觉大细胞系统上。本文就目前阅读障碍在视觉功能方面的研究进展做一综述。

During the past 100 years, different researchers have diverse views in the etiology and pathogenesis of dyslexia. Now some researchers think dyslexia is due to the early developmental obstades of the cognitive and processing capadty of voice and visual information. There are two important neuroethological hypothesis, the Impairment of Vode procession and the Impairment of Foundmental Perceptive procession. Simultaneously, the patients were accompanied by a certain degree of abnormal structure and functions of nervous system, as demonstrated by magnocellular system in the visual pathway. The present paper reviews on the research progress of dyslexia and vision function.
