Belonging to multiple groups is an important feature of our social lives. However, it is largely unknown if it is related to individual differences in cognitive performance. Given that changing self-identities linked to each group requires cognitive operations on knowledge bases associated with each group, the extent to which people belong to multiple groups may be related to individual differences in cognitive performance. Therefore, the main objective of this study was to test if multiple group membership is related to executive function task performance. A socioeconomically diverse sample of 395 individuals in Indonesia participated in this study. Our results show that multiple group membership was positively related to the 3-back working memory performance. However, we also found that this relationship was significant only among participants with high (not median or low) SES. We also observed that Contact diversity was negatively related to working memory performance among participants with low SES. Our results show that the complexity of our social lives is related to individual differences in executive function performance, although this seems to be constrained by SES.
属于多个群体是我们社会生活的一个重要特征。然而，目前还不清楚它是否与认知表现的个体差异有关。鉴于与每个群体相关联的自我身份的变化需要对与每个群体相关联的知识库进行认知操作，人们属于多个群体的程度可能与认知表现的个体差异有关。因此，本研究的主要目的是检验多重群体归属是否与执行功能任务表现相关。本研究在印度尼西亚的一个具有社会经济多样性的 395 人样本中进行。我们的结果表明，多重群体归属与 3 回工作记忆表现呈正相关。然而，我们还发现，这种关系仅在 SES 较高（而不是中位数或较低）的参与者中显著。我们还观察到，在 SES 较低的参与者中，接触多样性与工作记忆表现呈负相关。我们的结果表明，我们的社会生活的复杂性与执行功能表现的个体差异有关，尽管这似乎受到 SES 的限制。
