Abstract:
Introduction: Based on the previous studies, we know that the hemispheric lateralization
defects, increase the probability of psychological disorders. We also know that dominant limb is
controlled by dominant hemisphere and limb preference is used as an indicator for hemisphere
dominance. In this study we attempted to explore the hemispheric dominance by the use of three
limbs (hand, foot and eye).
Methods: We performed this survey on two samples, psychiatric patients compared with normal
population. For this purpose, knowing that the organ dominance is stabilized in adolescence, and
age has no effect on the people above 15, we used 48 high school girls and 65 boys as the final
samples of normal population. The patient group included 57 male and 26 female who were
chronic psychiatric patients.
Results: The result shows that left-eye dominance is more in patients than the normal group
(P=0.000) but the handedness and footedness differences are not significance. In psychotic,
bipolar and depressive disorders, eye dominance had significant difference (P=0.018). But this is
not true about hand and foot dominance.
Discussion: Our findings proved that generally in psychiatric patients, left-eye dominance is
more common, left-eye dominance is also more in psychotic and depressive disorders. It is less
common in bipolar disorders.
