从家庭到国家,在很大程度上,社会群体中的个体之间的联系是他们共同的信仰、规范和记忆。人们认为,这些紧急结果的发生是因为个体之间的交流导致了整个社区的同步。在这里,我们在实验室创建的网络中使用实验操作来研究对话的时间动态如何塑造集体记忆的形成。我们表明,当个体在集群之间架起桥梁时(即,桥接纽带)在一系列联网交互中的早期进行通信,与个体首次在集群内交互时相比,网络达到更高的记忆收敛(即,集群关系)。这种效果,我们发现,是由于初始信息多样性和累积重叠随着时间的推移之间的权衡。我们的方法提供了一个框架来分析和设计干预社交网络,优化信息共享,减少信息泡沫和两极分化的可能性。
From families to nations, what binds individuals in social groups is, to a large degree, their shared beliefs, norms, and memories. These emergent outcomes are thought to occur because communication among individuals results in community-wide synchronization. Here, we use experimental manipulations in lab-created networks to investigate how the temporal dynamics of conversations shape the formation of collective memories. We show that when individuals that bridge between clusters (i.e., bridge ties) communicate early on in a series of networked interactions, the network reaches higher mnemonic convergence compared to when individuals first interact within clusters (i.e., cluster ties). This effect, we show, is due to the tradeoffs between initial information diversity and accumulated overlap over time. Our approach provides a framework to analyze and design interventions in social networks that optimize information sharing and diminish the likelihood of information bubbles and polarization.
