封面故事:毕鸿燕领导的研究小组在正常成年阅读者中探讨了视觉大细胞通路对汉字识别的影响.通过同时调控汉字材料的时间频率和空间频率来区分大细胞通路敏感条件和正常视觉条件,并采用整体/部件判断任务来比较被试在每种条件下加工汉字整体和部件信息的过程.研究发现:在大细胞条件下,被试判断整字比判断部件的反应更快、错误率更低,即出现整体优先效应;而在正常视觉条件下,整体和部件判断的反应时和错误率均无显著差异.上述研究结果表明视觉大细胞通路促进了汉字整体信息的加工.基于前人提出的发展性阅读障碍大细胞通路缺陷理论,该研究的结果有助于进一步揭示视觉大细胞通路与阅读的关系,并为探究阅读障碍的致病机制及干预方法提供了有意义的启示.

Cover Story:The present study aimed to examine the role of visual magnocellular pathway in the recognition of Chinese character. Twenty-four university students took part in this study. We simultaneously manipulated the spatial frequency and temporal frequency of Chinese characters in order to dissociate two visual conditions, that is, the visual magnocellular (M) condition and visual control condition. And a global/local decision task was adopted here to get the comparison between global processing and local processing within each visual condition. The reaction time and error rate were recorded. Results showed that in the M condition, participants responded faster in global decision than in local decision, a global precedence effect appeared; while non-significant difference in the control condition. Similarly, higher error rate was found for local decision comparing with global decision only in the M condition. It suggested that the visual magnocellular system contributes to the global processing of Chinese character.
