Abstract

The purpose of the research was to examine whether the perception of the three dimensional path of a moving object was systematically distorted by disconjugate eye movements. Subjects were required to report which part of the path of a vertically moving luminance- defined target object was closer to themselves while pursuing an object translating in depth dimension. Systematic perceptual distortion of the 3D path of the vertically moving luminance-defined object was found during disconjugate eye movements. Presence of a reference stimulus reduced the amount of perceptual distortion, although it did not completely remove it. This result implies that the eye movement-induced disparities are not completely compensated for with eye position information and that reference information might be importantly used in the compensation of eye movement-induced disparities.
