Visual thresholds for flicker detection and light detection were measured for white and yellow flickering targets superposed on a white adapting field. The flicker frequency was set so that flicker detection thresholds always exceeded the light detection thresholds. The difference between the two types of thresholds was found to be smaller for yellow targets than for white targets. The most likely explanation of this result is that short-wavelength cones contribute to achromatic sensitivity at low temperal frequencies.
在白色适应场中叠加白色和黄色闪烁目标，测量了闪烁检测和光检测的视觉阈值。设置闪烁频率，使闪烁检测阈值始终超过光检测阈值。发现黄色目标的两种阈值之间的差异比白色目标的小。对这一结果最可能的解释是，短波长视锥细胞在低时间频率下有助于非彩色视觉敏感度。
