人們在交互過程中會同時表征自我和他人相關的信息,形成社會性聯合表征。然而,自我和他人相關信息是以整合還是分離的形式存在,這一問題尚未厘清。本研究以工作記憶蓬佐錯覺為指標展開了探討。實驗中要求兩名被試分別記憶部分構成蓬佐錯覺的線段并回憶。結果發現,競爭和合作場景下的個體不僅表征了他人相關的信息,還將其和自身相關的信息進行了整合,形成工作記憶蓬佐錯覺效應,表明社會交互條件下會自動整合成社會性共同表征。

Previous studies found that people automatically represent others’ tasks just as representing their own.However,the mechanism of shared representations remains unknown,more precisely,we do not know whether the representations for oneself and others are shared or separated. In the present study,we developed a new paradigm by combining the working memory Ponzo illusion and the Social Simon task to investigate the mechanism of shared representations.Results showed that when four Ponzo figure lines were distributed into two parts for two participants to remember,the working memory Ponzo illusion effect occurred( the upper line is recalled longer than the lower one),which was consistent with the resultsobtained in the condition when one person was required to remember four Ponzo lines(Experiment 1).These results suggested that in social situation,people automatically represented others’ task information and integrated it with their own. Moreover,the integration is stable and not influenced by different social interaction types such as cooperation and competition(Experiment 2).
