消失文本词窗口条件下八年级学生阅读的眼动特征

摘要

The disappearing text paradigm was used to investigate how early in a fixation the eighth graders were able to obtain sufficient information from the text to read when disappearing unit was a word. Compared with the control condition, for the mean fixation duration, the differences were apparent when words disappeared after 40ms and 60ms in the experiment. There was no significant difference between the conditions which the words disappeared after 80ms and the control condition. However no disappearing conditions interrupted the total reading time. So we concluded that for eighth-grade children, when they processed disappearing text most of the visual information necessary for reading could be acquired within the initial 50-60ms during a fixation in Chinese reading.%本研究通过消失文本实验范式，考察八年级阅读者在刺激材料以双字词为消失单元时，从视觉刺激中提取语义信息的必要呈现时间。实验发现40ms以上延迟时间的消失文本并不影响读者的总阅读时间，但在80ms消失的条件下，注视时间与控制条件下的差异不再显著。结果支持眼动控制理论中的认知控制模型。
