Following exposure to a moving grating of bars differing only in luminance, a motion aftereffect (MAE) is observed on a stationary grating of bars differing only in chrominance. This suggests that the motion of equiluminous chromatic stimuli is sensed by a channel that responds to both luminance and chrominance and not by a separate channel specialized for the motion of colored stimuli. However, adding color to a low contrast luminance stimulus actually reduces its effectiveness at creating or nulling a MAE, indicating that the response of the motion pathway to color is qualitively different from its response to luminance. In addition, a chromatic stimulus demonstrates a dissociation between perceived speed, MAE speed and speed required to null the MAE that is absent for a luminance stimulus.
在暴露于仅亮度不同的条形移动光栅后，在仅色度不同的静止条形光栅上观察到运动后效（MAE）。这表明等亮度色刺激的运动是由一个对亮度和色度都有反应的通道感知的，而不是由一个专门用于彩色刺激运动的单独通道感知的。然而，向低对比度亮度刺激添加颜色实际上会降低其产生或消除MAE的有效性，这表明运动通路对颜色的反应在性质上与其对亮度的反应不同。此外，色刺激在感知速度、MAE速度和消除MAE所需速度之间表现出分离，而亮度刺激不存在这种分离。
