The motion aftereffect (MAE) is an illusory drift of a physically stationary pattern induced by prolonged viewing of a moving pattern. Depending on the nature of the test pattern the MAE can be phenomenally different. This difference in appearance has led to the suggestion that different underlying mechanisms may be responsible and several reports show that this might be the case. Here, we tested whether differences in MAE duration obtained with stationary test patterns and dynamic test patterns can be explained by a single underlying mechanism. We find the results support the existence of (at least) two mechanisms. The two mechanisms show different characteristics: the static MAE (i.e. the MAE tested with a static test pattern) is almost completely stored when the static test is preceded by a dynamic test; in contradistinction, the dynamic MAE is not stored when dynamic testing is preceded by a static test pattern.
运动后效（MAE）是指因长时间观看运动模式而导致的物理静止模式的虚幻漂移。根据测试模式的性质，运动后效在现象上可能会有所不同。这种外观上的差异表明可能存在不同的潜在机制，并且有几份报告表明情况可能确实如此。在这里，我们测试了使用静止测试模式和动态测试模式获得的运动后效持续时间的差异是否可以由单一潜在机制来解释。我们发现结果支持（至少）两种机制的存在。这两种机制表现出不同的特征：静态运动后效（即用静态测试模式测试的运动后效）在静态测试之前进行动态测试时几乎会完全保留；相反，当动态测试之前使用静态测试模式时，动态运动后效不会保留。
