不同难度阅读材料对阅读知觉广度影响的眼动研究

The Perceptual Span and Eye Movements in Reading Chinese Materials of Different Degrees of Difficulty

采用经典的呈现随眼动变化技术,以Eyelink Ⅱ眼动仪为工具,考察材料难度和窗口大小对中文句子阅读的影响。实验设计为2(材料难度:难,易)×5(窗口大小:1个字,3个字,5个字,7个字和整行)被试内实验设计,被试为15名在校大学生。研究结果表明:(1)阅读容易材料时的知觉广度为5个字。(2)阅读困难材料时知觉广度为3-5个字。

To explore how the difficulty of material and the size of display windows influence Chinese sentence-reading, an Eyelink II eye tracker and the classical eye-movement-contingent display changes paradigm were used in the experiment. The experiment design was a 2 （difficulty levels of material： difficult, easy） × 5 （display window sizes： 1 character, 3 characters, 5 characters, 7 characters and the whole sentence） within-subject design. 15 college students participated in the experiment. The results were as follows： （1）To easy material, the perceptual span of reading was 5 characters; （2） To difficult material, the perceptual span of reading was 3-5 characters.
