A ROTATIONAL STEREOSCOPIC 3-DIMENSIONAL MOVEMENT AFTEREFFECT

A stereoscopic rotational movement aftereffect (MAE) and a stereoscopi c bi-directional MAE were generated by rotation of a cyclopean random dot cylinder in depth and by movement of two cyclopean random dot plan es in opposite directions, respectively. Cross-adaptational MAEs were also generated on each other, but not with stimuli lacking any dispari ty. Cross-adaptation MAEs were generated between stereoscopic and non- stereoscopic random dot stimuli moving in the one X/Y plane. Spontaneo us reversals in direction of movement were observed with bistable stim uli lacking disparity. Two models of the middle temporal area were con sidered which might explain both the stereoscopic MAEs and the spontan eous reversals. (C) 1998 Elsevier Science Ltd. All rights reserved.
