当观看静态与动态测试显示器时，对给定方向上的运动的长期适应产生明显不同的视觉运动后效（MAE）。动态MAE可以用真实的运动来精确模拟，而静态MAE则不能。此外，动态MAE的幅度取决于在适应期间经历的运动方向的带宽，而静态MAE不取决于。显然，一个固定的模式不直接激活运动适应过程中受影响的神经机制，而动态的视觉显示。这些结果表明，传统的解释MAE需要修改。
Prolonged adaptation to motion in a given direction produces distinctly different visual motion aftereffects (MAEs) when viewing static vs. dynamic test displays. The dynamic MAE can be exactly simulated by real motion, whereas the static MAE cannot. In addition, the magnitude of the dynamic MAE depends on the bandwidth of motion directions experienced during adaptation, whereas the static MAE does not. Evidently a stationary pattern does not directly activate the neural mechanisms affected during motion adaptation, whereas a dynamic visual display does. These results imply that the traditional explanation of the MAE needs modification.
