摘要
以大学生为被试,探讨文本阅读过程中,疲劳和心理负荷因素对瞳孔大小的调节作用。实验一主要检验文本阅读中的疲劳效应;实验二分析不同文本加工水平者的瞳孔变化差异,以探讨疲劳和心理加工对瞳孔变化的作用。结果表明:在文本阅读中,疲劳会使瞳孔缩小,心理负荷增大会使瞳孔放大,一定的心理负荷可以起到维持瞳孔大小不变的作用;疲劳和心理负荷因素对瞳孔大小的调节存在颉颃效应。
In the current work, we conducted 2 experiments to observe the regulating effect of fatigue and mental load on pupil size in college students' text reading. In experiment 1, the role of fatigue effect in text reading was examined. Different changes in pupil size of subjects with different text-processing ability were analyzed. In experiment 2, we investigated fatigue effect and mental processing effect on pupillary responses. The results showed that in text reading, pupil diameter decreased with fatigue, whereas increased with mental load and persisted with sustained mental load; regulation of fatigue and mental load on pupil size existed counter effect.
