A rotational stereoscopic 3-dimensional movement aftereffect.
A stereoscopic rotational movement aftereffect (MAE) and a stereoscopic bi-directional MAE were generated by rotation of a cyclopean random dot cylinder in depth and by movement of two cyclopean random dot planes in opposite directions, respectively. Cross-adaptational MAEs were also generated on each other, but not with stimuli lacking any disparity. Cross-adaptation MAEs were generated between stereoscopic and non-stereoscopic random dot stimuli moving in the one X/Y plane. Spontaneous reversals in direction of movement were observed with bistable stimuli lacking disparity. Two models of the middle temporal area were considered which might explain both the stereoscopic MAEs and the spontaneous reversals.
