Abstract

The purpose of the present research was to examine whether Pulfrich effect, binocular disparity and SFM (structure-from-motion) were processed by a common neurophysiological mechanism. Subjects adapted to a rotating semitransparent random dot cylinder whose rotation direction was defined by binocular disparity, Pulfrich effect or combination of them and reported the rotation direction of adaptation test stimulus, another rotating cylinder whose rotation direction was ambiguously defined by SFM. Subject perceived that the test stimulus rotated in the direction opposite to that of adapting stimulus defined by binocular disaprity or Pulfrich effect. Interestingly, the adaptation effect changed systematically depending on the relative strength of binocular disparity and Pulfrich effect when the directions of adapting stimuli defined by them are in conflicts. These results imply that binocular disparity, Pulfrich effect and SFM are processed by a common neurophysiological mechanism.
