材料难易度对汉语阅读活动影响的眼动研究

Eyemovement Study in Reading of Different Difficulty of Chinese Sentences

采用经典的刺激呈现随眼动变化技术中非对称式窗口设计,以Eyelink Ⅱ眼动仪为工具,考察材料难度和窗口大小对大学生中文句子阅读的影响。实验设计为2(材料难度:难,易)×8(窗口大小:C,R1,R2,R3,R4,LR4,L2R4,整行)被试内实验设计,被试为15名在校大学生。结果发现:(1)难材料阅读知觉广度为被注视汉字左侧1个汉字到右侧2个汉字之间;(2)易材料阅读知觉广度为被注视汉字左侧1-2个汉字到右侧3-4个汉字之间。(3)知觉广度的左右不对称性受阅读材料难易度的影响,较易材料的阅读知觉广度的不对性大于较难材料的阅读知觉广度。

To explore how do the difficulty of material and the size of display windows influence the Chinese sentences reading, 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）~8（display window sizes： lcharacter, 2characters, 3characters, 4characters, 5characters, 6characters, 7characters and the whole sentence） within-subject design. 15 college students participated in the experiment. We got following results： （1）the perceptual span of Chinese reading in difficult materials is lcharacter to the left and 2characters to the right of the fixation word; （2） To easy material, the perceptual span of reading is 1-2characters to the left and 3-4characters to the right of the fixation word. （3） The unsymmetrical perceptual span is affected by the difficulty of the sentences.
