Memory displacement of an object with motion lines

This study explored how motion lines (ML) can contribute to the memory displacement of an object. Three experiments were conducted to examine the memorized position of a target with ML using manual localization tasks, revealing that the reproduced position was biased in the direction implied by the ML. Two further experiments successfully ruled out the possibility that the memory displacement stemmed from a repulsive manual localization tendency, an attention repulsion-like effect, or perceptual illusory displacement of the object. These results indicated that ML trigger anticipation of the future position of the object, resulting in memory displacement.
