Abstract: Three-word pairs were used to construct two structures of social situations: circular transitive structure and linear transitive structure, and the processing mechanism of social structure was investigated by the Plausible Scenario Judgment Task and ERP technology. The results show that compared with the linear structure, the circular structure induces a significant priming effect, induces a smaller P200, a larger N400, and a smaller P600. This indicates that the subjects have the cognitive characteristics of circular structural balance. Possible exclamation points to the circular transitive structure schema preference of Chinese culture and supports the cultural constructivist view of social structure cognition.

Key words: Circular transitive structure, Linear transitive structure, Priming advantage effect, ERP technology

摘要： 采用三词对材料构成两种结构的社会情境：环性传递结构和线性传递结构，通过合理情境判断任务和脑电技术，探讨社会结构的加工机制。结果发现，与线性结构相比，环性结构引发显著的启动优势效应，诱发额区和中央区更小P200波幅、更大N400波幅和更小P600波幅。这表明，被试对环性社会结构具有自动化的整体加工优势。可能的解释指向中华文化的环性结构图式偏好，支持社会结构认知的文化建构性观点。
