优化团队绩效是人类协作的主要目标之一，并促使人们彼此共享资源。个体之间的连通性决定了群体成员如何获取和共享资源，然而，关于互连网络的拓扑结构与群体绩效之间关系的经验知识却很少。为了加深我们对这种关系的理解，我们在虚拟现实中创建了一个游戏，在这个游戏中，小团队为了一个共同的目标而合作。我们对30组玩家进行了一系列的实验，每组三名玩家，他们玩了三轮游戏，每轮都有不同的网络拓扑结构。我们假设，由于两个主要因素，更高的网络连接将提高群体绩效：个人共享资源的能力和他们的觉醒。我们发现，组的性能与整体网络的连通性是正相关的，虽然注册高原效应，可能与拓扑特征在节点一级。更深入的分析组动力学表明，组的性能调制的高性能和低性能的组中的连接。我们的研究结果提供了深入了解复杂的群体结构，对有效的人类团队的设计。
Optimizing group performance is one of the principal objectives that underlie human collaboration and prompts humans to share resources with each other. Connectivity between individuals determines how resources can be accessed and shared by the group members, yet, empirical knowledge on the relationship between the topology of the interconnecting network and group performance is scarce. To improve our understanding of this relationship, we created a game in virtual reality where small teams collaborated toward a shared goal. We conducted a series of experiments on 30 groups of three players, who played three rounds of the game, with different network topologies in each round. We hypothesized that higher network connectivity would enhance group performance due to two main factors: individuals’ ability to share resources and their arousal. We found that group performance was positively associated with the overall network connectivity, although registering a plateau effect that might be associated with topological features at the node level. Deeper analysis of the group dynamics revealed that group performance was modulated by the connectivity of high and low performers in the group. Our findings provide insight into the intricacies of group structures, toward the design of effective human teams.
