当观察者被要求定位运动目标的起始位置或偏移位置时，他们通常会在运动方向上犯定位误差。类似地，当观察者判断与闪光对齐的移动目标时，该目标似乎引领着闪光。这些误差分别称为弗洛利希效应、表象动量和闪光滞后效应。本研究比较了三种错位误差的大小。在实验1中，闪光与移动目标的起始位置、中间位置或偏移同时出现。观察人员随后判断了闪光出现时移动目标的位置。实验2和实验3完全与定位运动目标的起始和偏移有关。当观察者相对于闪光出现时的时间点定位位置时，在初始位置和中间位置观察到在移动方向上明显的错位。相反，在最终位置发生了与运动方向相反的定位错误。当观察者被要求忽略闪光时(或根本没有闪光时)，在初始位置观察到减少的误差(或没有误差)，并且在最终位置仅发生移动方向上的微小误差。提出了一个综合模型，该模型提出了一个共同的潜在机制，但强调了Frohlich效应、闪光滞后效应和代表性动量的具体加工成分。
When observers are asked to localize the onset or the offset position of a moving target, they typically make localization errors in the direction of movement. Similarly, when observers judge a moving target that is presented in alignment with a flash, the target appears to lead the flash. These errors are known as the Frohlich effect, representational momentum, and flash-lag effect, respectively. This study compared the size of the three mislocalization errors. In Experiment 1, a flash appeared either simultaneously with the onset, the mid-position, or the offset of the moving target. Observers then judged the position where the moving target was located when the flash appeared. Experiments 2 and 3 are exclusively concerned with localizing the onset and the offset of the moving target. When observers localized the position with respect to the point in time when the flash was presented, a clear mislocalization in the direction of movement was observed at the initial position and the mid-position. In contrast, a mislocalization opposite to movement direction occurred at the final position. When observers were asked to ignore the flash (or when no flash was presented at all), a reduced error (or no error) was observed at the initial position and only a minor error in the direction of the movement occurred at the final position. An integrative model is proposed, which suggests a common underlying mechanism, but emphasizes the specific processing components of the Frohlich effect, flash-lag effect, and representational momentum.
