An eccentrically positioned afterimage, viewed in the dark, will disappear if the eye is positioned so that the afterimage now projects to a more extreme location relative to straight ahead. It was found that the afterimage disappeared when it projected to a location which corresponded to the edge of the visual field defined by the brow, cheek, and nose. This suggests that visibility of stimuli from those retinal regions shadowed by the head is influenced by eye-position information.
在黑暗中观察到的偏心定位后像，如果眼睛的位置使得后像相对于正前方投射到更极端的位置，那么该后像将会消失。研究发现，当后像投射到与由眉毛、脸颊和鼻子所界定的视野边缘相对应的位置时，它就会消失。这表明，来自那些被头部遮挡的视网膜区域的刺激的可见性受到眼睛位置信息的影响。
