Relation between pupillary changes and brain wave as an index of human activity

教师在课堂上很难判断学习者的心理活动程度。教育心理学的研究描述了几种方法，如观察或内省，通过这些方法，可以从长期的学习者反应中学习到结果。然而，最有效的是通过真实的时间生物信息如GSR来进行这种确定（皮肤电反射），在有视觉刺激和无视觉刺激以及控制亮度的条件下，研究了听觉指令对瞳孔变化的影响。瞳孔的变化与视觉刺激的关系，以及听觉指令对瞳孔变化的影响。当受试者观看视觉图案时，测量了对音频指令的反应。当给出音频指令时，在几种条件下观察到人类瞳孔的变化。听觉指令导致瞳孔放大，这种现象与视觉刺激和图案亮度无关。较低的亮度也会导致瞳孔扩大。

It is not easy for teachers to determine the extent of a learner's mental activities in class. Studies of educational psychology describe several methods such as observation or introspection by which the results have been learned from learner response over a long term. Most effective, however, is to make this determination by real time biological information like GSR(galvanic skin reflex), heart rate and so on.The pupil of the eye dilates during a period of mental activity and this biological phenomenon can be utilized in educational evaluations.The effects of audio instructions on pupillary canges were investigated under several cunditions with or without visual stimuli and under controlled brightness.Pupillary changes were measured in response to audio instruction while a subject looked at a visual pattern.Human pupillary changes are observed under several conditions when audio instructions are given. Audio instruction causes the pupil to dilate and this phenomenon is independent of visual stimuli and pattern brightness. Lower levels of brightness also cause dilation of the pupil.
