简单的反应时间，正弦波光栅的1，4和10 C/度的测量作为一个函数的光栅的可检测性。在一定的检测范围内，反应时间随空间频率的增加而增加。假设同样可检测的光栅在视觉系统中产生相同水平的响应，则反应时间的这种增加反映了随着空间频率增加而感知延迟的增加。
Simple reaction time to sine-wave gratings of 1, 4 and 10 c/deg was measured as a function of the detectability of the gratings. Reaction time increased with spatial frequency over a range of detectabilities. Assuming that equally detectable gratings produce equivalent levels of response in the visual system, this increase in reaction time reflects an increase in perceptual latency as spatial frequency is increased.
