我们研究的目的是探查视觉大细胞系统在汉字识别中的作用.研究以24名大学生正常阅读者作为被试,通过调控汉字材料的空间频率和时间频率区分出大细胞通路敏感刺激和正常视觉刺激两种条件,并采用整体/部件字形判断任务来比较在不同视觉条件下,被试加工汉字整体和部件信息的过程,记录反应时和错误率.结果表明,在大细胞条件下,被试对整字信息的判断要显著快于对部件的判断,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无显著差异.同时,在大细胞条件下,被试进行部件判断的错误率显著高于整体判断,在正常视觉条件下两者差异不显著.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.
The purpose of our study is to explore the role of visual macrophages in Chinese character recognition.Studies use 24 normal college students as subjects to distinguish the macrophage pathway-sensitive stimuli and normal visual stimuli by regulating the spatial frequency and time frequency of Chinese character materials Two kinds of conditions, and the overall / part shape to determine the task to compare under different visual conditions, the process of processing the whole Chinese characters and parts information process, record the reaction time and error rate.The results show that under the conditions of large cells, The whole word information judgment is significantly faster than the judgment of the components, that is, the overall priority effect, while in the normal visual conditions, the overall and component judgment no significant difference in response to the same time, under the conditions of large cells, The error rate was significantly higher than the overall judgment, under normal visual conditions, there was no significant difference between the two.The results show that visual macrophages promote the processing of Chinese characters as a whole.
