Dimensional approach to the study of sighting dominance

This study proposes a dimensional and noncategorical approach to research on sighting dominance. Let us suppose that no eye dominance exists as well as results concerning right and left eye dominance. We modified a classical alignment test to measure along a continuum the ocular dominance of 47 female undergraduate students in psychology. Data seem to confirm the hypothesis emphasizing the presence of subjects with no ocular dominance as well as right- and left-dominance subjects. Moreover, another group has been classified. The subjects with fluctuating dominance show an alternation in their dominance. Thus an hypothesis of the functionality of the two hemispheres is suggested.
