Side bias in schizophrenia: hand, foot, eye, and ear.
Schizophrenics and normal controls were examined for their side (lateral) bias in terms of hand, foot, eye, and ear. Preference and performance measures were taken. The findings indicated a rightward bias for both measures in controls and in participants with schizophrenia. Side pattern was congruent between those with and without schizophrenia, with limb lateralization (hand, foot) orthogonal to sense-organ lateralization (eye, ear). Analysis of right- and left-side responses indicated a significant group difference for eye bias and ear bias as a function of response measures, preference, and performance.
