Substantial verbal IQ (VIQ)-performance IQ (PIQ) discrepancies may reflect brain dysfunction. The authors examined 159 patients with schizophrenia (115 men and 44 women) or schizoaffective disorder (25 men and 19 women) and 79 normal participants (33 men and 46 women), calculated mean VIQ-PIQ discrepancy scores by sex and diagnosis, and identified persons with large VIQ-PIQ discrepancies (15-point difference in either direction). Schizophrenic/schizoaffective men had a larger mean VIQ-PIQ discrepancy than did other groups. The proportion of all patients with either VIQ > PIQ or PIQ > VIQ (17.8%) was not significantly different from that of normal participants (22.8%). However, significantly more men than women with schizophrenia exhibited a VIQ > PIQ pattern (20% vs. 3.2%). No unusual discrepancy patterns were noted among normal participants. Results were interpreted in light of theories of hemisphere dysfunction in schizophrenia.
显著的言语智商（VIQ）与操作智商（PIQ）差异可能反映脑功能障碍。作者研究了159例精神分裂症患者（115名男性和44名女性）或分裂情感性障碍患者（25名男性和19名女性）以及79名正常参与者（33名男性和46名女性），按性别和诊断计算了平均VIQ - PIQ差异分数，并确定了VIQ - PIQ差异较大的人（任一方向相差15分）。患有精神分裂症/分裂情感性障碍的男性比其他组有更大的平均VIQ - PIQ差异。所有VIQ＞PIQ或PIQ＞VIQ的患者比例（17.8%）与正常参与者的比例（22.8%）无显著差异。然而，患有精神分裂症的男性中表现出VIQ＞PIQ模式的显著多于女性（20%对3.2%）。在正常参与者中未发现异常的差异模式。根据精神分裂症半球功能障碍理论对结果进行了解释。
