SIDE BIAS IN SCHIZOPHRENIA - HAND, FOOT, EYE, AND EAR

Schizophrenics and normal controls were examined for their side (later al) bias in terms of hand, foot, eye, and ear. Preference and performa nce measures were taken. The findings indicated a rightward bias for b oth measures in controls and in participants with schizophrenia. Side pattern was congruent between those with and without schizophrenia, wi th limb lateralization (hand, foot) orthogonal to sense-organ laterali zation (eye, ear). Analysis of right-and left-side responses indicated a significant group difference for eye bias and ear bias as a functio n of response measures, preference, and performance.
