The study reported herein explored the comprehension of metaphor and irony in schizophrenia during remission, and examined the role of IQ and a theory of mind. Performance of 29 Schizophrenic patients in remission and 22 healthy controls was compared on metaphor and irony comprehension tasks and first- and second-order theory of mind tasks. Participants' IQs were measured using the Wechsler Adult Intelligence Scale-Revised, and the symptoms of individuals with schizophrenia were assessed using the Positive and Negative Syndrome Scale. The results showed that patients with schizophrenia were impaired in their comprehension of metaphor and irony as compared with healthy controls. A theory of mind deficit was found in patients with remitted schizophrenia. The comprehension of metaphor was significantly correlated with second-order false belief understanding and the comprehension of irony was not significantly related to theory of mind. IQ and verbal IQ did not explain the deficit of metaphor and irony comprehension. These findings were not explained by Happé's [Happé, F.G.E., 1993. Communication competence and theory of mind in autism: a test of relevance theory. Cognition 48, 101-119] theory and the shared semantic understanding requirement was discussed.
本文所报告的研究探讨了精神分裂症缓解期患者对隐喻和反讽的理解，并考察了智商和心理理论的作用。对29名处于缓解期的精神分裂症患者和22名健康对照者在隐喻和反讽理解任务以及一阶和二阶心理理论任务上的表现进行了比较。使用韦氏成人智力量表修订版测量参与者的智商，并使用阳性和阴性症状量表评估精神分裂症患者的症状。结果显示，与健康对照者相比，精神分裂症患者在隐喻和反讽理解方面存在缺陷。在缓解期精神分裂症患者中发现了心理理论缺陷。隐喻理解与二阶错误信念理解显著相关，而反讽理解与心理理论无显著关联。智商和言语智商无法解释隐喻和反讽理解方面的缺陷。这些发现无法用哈佩[哈佩，F.G.E.，1993年。自闭症中的沟通能力和心理理论：对关联理论的检验。认知48，101 - 119]的理论来解释，并对共享语义理解要求进行了讨论。
