瞳孔反应的对比度反转的可变检查大小和对比度的棋盘图案进行了测量。结果表明，瞳孔系统对对比度反转有反应。有人认为，这种反应是由局部亮度变化引起的光反射。瞳孔传入的总和特性被认为是。还已经发现，瞳孔尺寸在没有对比度反转的任何影响的情况下，随着检查尺寸的变化而系统地变化。这种瞳孔的变化是否是由于视觉刺激的空间因素变化引起的视觉性能的变化进行了讨论。
Pupillary responses to the contrast reversal of a checkerboard pattern of variable check size and contrast were measured. The results show that the pupillary system is responsive to the contrast reversal. It is argued that this response is the light reflex caused by the local luminance change. The summation characteristics of the pupillary afferent are considered. It has also been found that the pupil size, without any influence from contrast reversal, systematically changes with the changes in the check size. Whether this pupillary change is caused by the variation in accommodative performance with changing spatial factors of visual stimulus is discussed.
