Virtual reality has been used to measure abnormal social characteristics, particularly in one-to-one situations. In real life, however, conversations with multiple companions are common and more complicated than two-party conversations. In this study, we explored the features of social behaviors in patients with schizophrenia during virtual multiparty conversations. Twenty-three patients with schizophrenia and 22 healthy controls performed the virtual three-party conversation task, which included leading and aiding avatars, positive- and negative-emotion-laden situations, and listening and speaking phases. Patients showed a significant negative correlation in the listening phase between the amount of gaze on the between-avatar space and reasoning ability, and demonstrated increased gaze on the between-avatar space in the speaking phase that was uncorrelated with attentional ability. These results suggest that patients with schizophrenia have active avoidance of eye contact during three-party conversations. Virtual reality may provide a useful way to measure abnormal social characteristics during multiparty conversations in schizophrenia.
虚拟现实已被用于测量异常的社交特征，尤其是在一对一的情境中。然而，在现实生活中，与多个同伴的对话是常见且比两人对话更为复杂的。在这项研究中，我们探索了精神分裂症患者在虚拟多方对话中的社交行为特征。23 名精神分裂症患者和 22 名健康对照者进行了虚拟三方对话任务，其中包括主导和辅助虚拟形象、带有积极和消极情绪的情境以及倾听和说话阶段。患者在倾听阶段表现出注视虚拟形象之间空间的数量与推理能力之间的显著负相关，并且在说话阶段表现出与注意力能力无关的增加的对虚拟形象之间空间的注视。这些结果表明，精神分裂症患者在三方对话中积极避免眼神接触。虚拟现实可能为测量精神分裂症中多方对话中的异常社交特征提供了一种有用的方法。
