词窗口条件下老年阅读者信息提取过程的眼动研究

本研究以眼动仪为工具,通过消失文本范式考察老年阅读者从视觉刺激中提取语义信息的必要呈现时间。实验一发现,老年阅读者阅读消失文本的视觉刺激必要呈现时间在120 ms以后。实验二在实验一的基础上,将消失时间设置为120 ms1、40 ms、160 ms、180 ms和200 ms。研究结果发现,老年阅读者阅读消失文本的必要延迟时间是200 ms,结果支持眼动控制理论中认知控制模型。

Old Adults' Eye Movements when Processing Disappearing Chinese Text

The disappearing text paradigm was used to investigate how early in a fixation the old adults are able to obtain sufficient information from the text to read when disappearing unit is a word.Compared with the control condition,the differences were significant when words disappeared after 40 ms,60 ms,80 ms,100 ms or 120 ms in experiment.1.The words disappeared after 120 ms,140 ms,160 ms,180 ms or 200 ms under the experimental condition in experiment 2. There was no significant difference between the condition in which the words disappeared after 200 ms and the control condition.The conclusion was that for the aged,when they processed disappearing text most of the visual information necessary for reading could be acquired within the initial 200 ms during a fixation in Chinese reading.
