Previous research on visual contingent aftereffects has been concerned with examining the effects of various parameters (e.g., spatial frequency and luminance) on the adaptation to, and decay of, contingent aftereffects. The current study tested the viability of using visual contingent aftereffects in a display context. Using established characteristics of contingent aftereffects, a program of contingent aftereffect adaptation was designed. Studies were conducted to determine if subjects who were adapted to see visual contingent aftereffects invoked by a visual display could achieve more rapid or certain identification of a display under low luminance conditions. The results confirmed (a) that contingent aftereffects can improve performance on a visual discrimination task requiring information from a display and (b) that contingent aftereffects are more enhanced at low levels of illumination.
先前关于视觉条件后效的研究主要关注于考察各种参数（如空间频率和亮度）对条件后效的适应及消退的影响。当前的研究测试了在显示环境中使用视觉条件后效的可行性。利用条件后效的既定特征，设计了一个条件后效适应程序。开展了多项研究，以确定适应于看到由视觉显示引发的视觉条件后效的受试者，在低亮度条件下是否能够更快速或更准确地识别显示内容。结果证实：（a）条件后效能够提高在需要显示信息的视觉辨别任务中的表现；（b）在低光照水平下，条件后效会得到更显著的增强。
