Eye Dominance and Stereopsis

Abstract

The contribution of eye dominance to the large individual differences found in the speed of stereoscopic fusion has been examined. The degree of sensory dominance was measured and correlated with the time taken to perceive depth in three random-dot stereograms of varying complexity. A significant positive correlation was found with the simple stereogram and nonsignificant positive correlations were obtained with the two more complex stereograms. The results indicate that a high degree of eye dominance can significantly interfere with the speed of fusion of simple stereograms.
