We investigate whether a motion aftereffect (MAE) can be induced by an isoluminant stimulus which contains colour contrast but no luminance contrast. We created a red/green chromatic stimulus, composed of red and green monochromatic grating added in antiphase, and corrected for the chromatic aberrations of the eye. We varied the ratio of the red to green luminances in the stimulus and found that there is no luminance ratio at which the MAE disappears. The results suggest that isoluminant stimuli can induce a MAE which is as great and sometimes greater than that induced by luminance contrast.
我们研究了一种包含颜色对比度但无亮度对比度的等亮度刺激是否能诱发运动后效（MAE）。我们创建了一种红/绿颜色刺激，它由反相添加的红色和绿色单色光栅组成，并校正了眼睛的色差。我们改变了刺激中红色与绿色亮度的比例，发现不存在使运动后效消失的亮度比例。结果表明，等亮度刺激能够诱发与亮度对比度诱发的运动后效一样大，有时甚至更大的运动后效。
