Impaired social functioning has been reported in patients with schizophrenia. This study aimed to examine characteristics of interpersonal behaviors in patients with schizophrenia during various social interactions using the virtual reality system. Twenty-six patients and 26 controls engaged in the virtual conversation tasks, including 3 positive and 3 negative emotion-laden conversations. Eye gaze and other behavioral parameters were recorded during the listening and answering phases. The amount of eye gaze was assessed as smaller in the patients than in the controls. A significant interaction effect of group status and emotional type was found for the listening phase. The amount of eye gaze in the patients inversely correlated with self-rated scores of assertiveness for the listening phase. These results suggest that the patients displayed inadequate levels of augmentations in eye gaze during negative emotional situations. These deficits should be considered in the treatment and social skills training for patients with schizophrenia.
已有报道称精神分裂症患者存在社交功能受损的情况。本研究旨在使用虚拟现实系统，考察精神分裂症患者在各种社交互动过程中的人际行为特征。26名患者和26名对照参与了虚拟对话任务，包括3次带有积极情绪和3次带有消极情绪的对话。在倾听和回答阶段记录了目光注视及其他行为参数。结果显示，患者的目光注视量低于对照组。在倾听阶段，发现了组别状态和情绪类型的显著交互作用。患者在倾听阶段的目光注视量与自我评定的 assertiveness 得分呈负相关。这些结果表明，患者在消极情绪情境下目光注视的增强水平不足。在对精神分裂症患者的治疗和社交技能训练中应考虑这些缺陷。
