Lateral differences in the detection of stereoscopic depth

The experiment investigated the hemifield differences in stereoscopic depth perception. Random dot stereograms (Julesz figures) producing the experience of a square appearing in front or behind the fixation plane were used as stimuli. The patterns in depth were exposed either in the left or in the right side of the stereograms for 30 msec. Three different magnitudes of depth were used. The results showed a higher amount of correct detections of depth in the left visual field than in the right visual field. The effects of direction and magnitude of depth were also significant. The hypothesis referring the observed results to the right hemisphere superiority in stereoscopic depth perception is discussed.
