Two hundred schizophrenics were compared to 200 normal controls on a measure of laterality that included handedness, footedness, and eye dominance scales. Schizophrenics showed more left-sidedness on the laterality score. The established relationship between motoric and cognitive aspects of functional brain asymmetry, found in neurological and normal populations, suggests that the leftward tendency of schizophrenics may be manifested in cognitive and conative functions as well. These results seem to corroborate previous findings indicating that schizophrenia might be related to left hemisphere dysfunction. No relationship was found between handedness and eye dominance either in the schizophrenic or the normal groups. This finding questions the assumption that eyedness-handedness nonconcordance is a pathological sign.
对200名精神分裂症患者和200名正常对照者进行了一项关于偏侧性的测量比较，该测量包括利手、利足和眼优势量表。精神分裂症患者在偏侧性得分上表现出更多的左侧倾向。在神经学和正常人群中发现的功能性脑不对称的运动和认知方面之间已确立的关系表明，精神分裂症患者的向左倾向也可能在认知和意志功能中表现出来。这些结果似乎证实了先前的研究结果，即精神分裂症可能与左半球功能障碍有关。在精神分裂症患者组和正常组中，利手和眼优势之间均未发现相关性。这一发现对利眼-利手不一致是一种病理标志的假设提出了质疑。
