The literature suggests that schizophrenics exhibit reduced or reversed cerebral lateral dominance relative to normal control subjects. An hypothesis which predicted reduced or reversed cerebral laterality for schizophrenics was tested on 60 young, familially right-handed males, with 20 men in each of the following three groups: schizophrenic inpatients, nonschizophrenic psychiatric inpatient controls, and normal controls. The subjects were administered a battery of seven measures of cerebral laterality. The application of multivariate statistical techniques showed groups did not differ significantly in the degree or the direction of their cerebral lateral dominance. Also there were no significant correlations between the measures of laterality. The findings suggest that cerebral lateral dominance is not necessarily altered concomitantly with psychopathology but rather that it is a complex phenomenon which may not be reliably determined on the basis of simple behavioral characteristics.
文献表明，与正常对照受试者相比，精神分裂症患者表现出大脑半球优势减弱或反转。一项预测精神分裂症患者大脑半球偏侧性减弱或反转的假设，在60名年轻的、家族性右利手男性中进行了测试，以下三组每组各有20名男性：精神分裂症住院患者、非精神分裂症精神科住院对照患者和正常对照者。对受试者进行了一系列七种大脑半球偏侧性测量。多变量统计技术的应用表明，各组在大脑半球优势的程度或方向上没有显著差异。此外，偏侧性测量之间也没有显著相关性。研究结果表明，大脑半球优势不一定与精神病理学同时改变，而是它是一个复杂的现象，可能无法根据简单的行为特征可靠地确定。
