Apparent Depth with Motion Aftereffect and Head Movement

Coupling a motion aftereffect (MAE) produced by horizontal shearing motion with a lateral head movement yields apparent depth. In experiments 1 and 2, respectively, the magnitude and the decay time of this apparent depth were measured. In experiment 3, it was found that the stimulus that produced an MAE in experiments 1 and 2 failed to do so when it was viewed while the head moved leftward and rightward and depth was seen.
