When observers are asked to localize the final position of a moving target, the judged position is usually displaced from the actual position in the direction of motion. The short-term time course of the displacement was investigated to test theories that attribute the localization error to spatial and temporal properties of human perception or to representational momentum. It was found that briefly after target offset, the judged position is already displaced in the direction of motion. It is argued that the shift results from eye movements after target offset that move the target's persisting image in the direction of motion.
当要求观察者确定移动目标的最终位置时，判断出的位置通常会在运动方向上偏离实际位置。研究了位移的短期时间进程，以检验将定位误差归因于人类感知的空间和时间特性或表征动量的理论。结果发现，在目标消失后不久，判断出的位置就已经在运动方向上发生了位移。有人认为，这种位移是由于目标消失后眼睛的运动，使目标的残留图像在运动方向上移动所致。
