运动后效（MAE）的特点，适应两个点的人口在正交方向上以不同的速度移动。实验结果表明：（1）当测试刺激的对比度（适应刺激后随机移动的点）高时，MAE的感知方向倾向于与速度更接近测试刺激的群体相反的方向;（2）当测试对比度较低时，MAE的方向对测试速度的依赖性不大，倾向于与速度优势种群相反的方向，人类的敏感性比另一个。基于生理发现的简单假设使我们能够解释复杂的结果。
Characteristics of motion aftereffect (MAE) following adaptation to two dot-populations moving in orthogonal directions at different speeds are reported. The results of experiments indicate that: (1) when the contrast of test stimuli (randomly moving dots presented after adapting stimuli) is high, the perceived direction of MAE inclines toward the opposite direction of the population which is closer in speed to the test stimuli than the other; (2) when the test contrast is low, the MAE direction is not so much depend on test speed and inclines toward the opposite direction of the population whose speed is more dominant in human sensitivity than that of the other. Simple assumptions based on physiological findings enable us to account for the complex results.
