A velocity effect for representational momentum


Observers were shown a rectangle at three orientations along a possible path of rotation. They were instructed to remember the third orientation in the sequence and then were presented with a rectangle at a fourth orientation that was either the same as, or slightly different from, the third orientation. Each observer tested was more likely to accept as “same” those distractors that were rotated slightly past the third orientation than those test items presented in the physically same position, and the degree of memory shift increased with increasing rate of presentation of the inducing displays.
