title: Stereopsis during continuous head motion.
abstract: This study investigated the degree to which the processing of stereoscopic information is degraded by side-to-side head rotations of amplitudes and frequencies known to disrupt binocular correspondence. Forced-choice recognition thresholds were obtained for a briefly presented stereoscopic test stimulus, formed from a dynamic random-element stereogram, under conditions of active head rotation. Thresholds were not impaired by such head movements, a result consistent with the hypothesis that precise binocular correspondence is not essential for the processing of stereoscopic information.
