The swinging doors of perception: stereomotion without binocular matching.
Until recently, it was considered necessary for features in the two eyes to be matched before the evaluation of differences in their locations (binocular disparities) could reveal depth information. Motion in depth can also be perceived binocularly from related changes in the locations of matched binocular features. However, unmatched features can arise when a binocular object occludes more dis...
متن کاملStereomotion scotomas occur after binocular combination
Stereomotion scotomas are a surprisingly common visual impairment that result in an observer's inability to accurately report the direction of an object's motion in depth in restricted parts of the visual field. In this study we investigated the role of binocular cues to motion in depth. Using stimuli containing only non-stationary cues to stereomotion, we measured sensitivity across the visual...
متن کاملBinocular Depth Perception without Familiarity Cues.
The reported phenomena were obtained through the use of special techniques. (i) All monocular depth and familiarity cues were removed from the stimuli (through the use of randomdot stereo patterns). (ii) The statistical and topological properties of the stimuli were precisely known (since they were generated according to a specific computer program). (iii) Convergence motions of the eye and pro...
متن کاملClosing the doors of perception.
ANESTHESIOLOGY is a discipline that is uniquely placed to contribute to the preeminent scientific quest of this century–namely the understanding of the neurologic mechanisms that underpin the phenomena of consciousness. The operating room is the crucible in which any putative theory should be tested. While acknowledging that there are arguments as to whether rapid eye movement sleep is really a...
متن کاملStereomotion perception for a monocularly camouflaged stimulus.
Under usual circumstances, motion in depth is associated with conventional stereomotion cues: a change in disparity and differences between object velocities in each monocular image. However, occasionally these cues are unavailable due to the fact that in one eye the object may be occluded by, or camouflaged against appropriately positioned binocular objects. We report two experiments concerned...
