Aftereffects of motion in depth based on binocular cues. Sakano, Y., Allison, R. S., & Howard, I. P. In Journal of Vision, volume 5, pages 732-732. 2005. ![Aftereffects of motion in depth based on binocular cues [link]](https://bibbase.org/img/filetypes/link.svg "link")
-1 doi abstract bibtex Purpose. Lateral motion aftereffects (MAEs) have been studied extensively. Less is known about MAEs in depth. We investigated whether adaptation to stimuli moving in depth induces MAEs in depth. Methods. The adaptation stimulus consisted of two frontoparallel planes, depicted by random-element stereograms, one above and one below the fixation point. The two planes repeatedly moved in depth in opposite directions for 2 minutes. The motion-in-depth was specified by interocular velocity differences and/or changing disparity by using the random elements which were spatially and temporally correlated in the two eyes (RDS), those which were spatially uncorrelated but temporally correlated (URDS), or those which were spatially correlated but temporally uncorrelated (DRDS). The test stimulus consisted of a RDS, URDS, DRDS or monocularly viewed random elements that did not move in depth. The subject pressed a key when any apparent motion in depth of the test stimulus ceased. Results and discussion. Under some conditions the test stimulus appeared to move in depth in the direction opposite to that of the adaptation stimulus (negative MAE). Specifically, adaptation to motion-in-depth of RDS and URDS produced MAEs in many test stimuli, while adaptation to DRDS produced little or no MAE in most test stimuli. While further experimentation is required, this finding suggests that adaptation to interocular velocity differences produces substantial MAEs in depth, but that adaptation to changing disparity produces little or no MAE. Also, a monocular test stimulus showed a MAE in a diagonal direction in depth. The depth component of the MAE under monocular test conditions indicates that binocular processes are involved in generating MAEs in depth.
