摘　　要：目的探讨精神分裂症一级亲属在错误信念任务加工中理解他人错误信念和应用他人错误信念的特点。方法采用基于计算机的指令交流实验范式分别探查30名未患病的精神分裂症一级亲属和44名正常对照理解他人错误信念和应用他人错误信念的能力。结果理解任务中,亲属组与对照组错误信念探测问题得分和事实探测问题得分差异均无统计学意义(均P>0.05)。应用任务中,亲属组错误信念指令问题得分差于对照组(P<0.01),事实指令问题得分差异无统计学意义(P=0.83)。结论精神分裂症一级亲属仅表现为错误信念应用的损害,对他人错误信念的理解加工则相对完好,在心理理论认知加工中存在知行分离的现象。Objective To investigate the ability of understanding others’false beliefs and the ability of applying others’false beliefs in first-degree relatives of schizophrenia, respectively. Methods Thirty first-degree relatives of schizophrenia and forty-four normal controls were involved in the present study. The ability of understanding others’ false beliefs and the ability of applying others’false beliefs was assessed with understanding task and applying task with a computerized referential communication paradigm, respectively. Results In understanding task, there was no significant difference between first-degree relatives and normal controls on False Belief Probe（Z=-0.26, P=0.80）and Reality Probe （Z=-0.41, P=0.68）. In applying task, first-degree relatives performed worse than normal controls on tasks of False Belief Command（Z=-4.09, P〈0.01）, but not Reality Command（Z=-0.21, P=0.83）. Conclusions The findings suggest a dissociation of understanding others’false beliefs from applying others’false beliefs in first-degree relatives of schizophrenia.
