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.
测量了对1、4和10周/度正弦波光栅的简单反应时，并将其作为光栅可检测性的函数。在一定的可检测性范围内，反应时随空间频率增加。假设同等可检测的光栅在视觉系统中产生同等水平的反应，反应时的这种增加反映了随着空间频率增加，感知潜伏期增加。
