发展性阅读障碍的理论及眼动研究

On the basis of cognition and biology, researchers put forward some theories about developmental dyslexia, such as phonological deficit, cerebellar deficit and the general magnocellular dysfunction,etc. And some characters in eye movement and some effective remedies have been found. But developmental dyslexia in Chinese is mainly confined to the fields of phonology and orthography. Other aspects have not been observed yet, such as eye movement. So primary theories about it are summarized. Then characters, such as fixation duration and frequency, saccade, regression and eyemovement mechanisms are discussed.
