我们研究了运动后效（MAE）是否可以偶然的环境。随机点移动的速度和速度交替出现。移动的点被一个开放的圆圈或一个开放的正方形包围。在长时间暴露于这些刺激后，发现MAE取决于周围的框架：当被与快速运动结合呈现的框架包围时，在随机方向上移动的点出现快速移动。这种效应持续了24小时，观察适配器和测试刺激时，不仅retinotopically，而且在同一spatiotopic位置。此外，即使当适配器和测试刺激呈现在不同的视网膜定位和空间定位位置，只要它们呈现在相同的半视野中，也观察到这种效果。这些结果表明，MAE不仅受刺激特征的影响，而且还受到周围环境的影响，他们建议，周围环境相关的MAE可能是在运动加工通路的高级阶段介导的。
We investigated whether motion aftereffects (MAE) can be contingent on surroundings. Random dots moving leftward and rightward were presented in alternation. Moving dots were surrounded by an open circle or an open square. After prolonged exposure to these stimuli, MAE were found to be contingent upon the surrounding frames: dots moving in a random direction appeared moving leftward when surrounded by the frame that was presented in conjunction with rightward motion. The effect lasted for 24 h and was observed when adapter and test stimuli were presented not only retinotopically, but also at the same spatiotopic position. Furthermore, the effect was observed even when the adapter and test stimuli were presented at different retinotopic and spatiotopic positions as long as they were presented in the same hemi-field. These results indicate that MAE would be influenced not only by the stimulus features, but also by their surroundings, and they suggest that the surround-contingent MAE might be mediated in the higher stage of the motion processing pathway.
