背叛或不背叛：如何通过EEG测量“读取”合作博弈中的人类行为
Defecting or not defecting: how to "read" human behavior during cooperative games by EEG measurements
摘要：
理解负责人类社会互动的神经机制是困难的，因为必须同时检查两个或多个人的大脑活动，并与观察到的社会模式相关联。我们引入了超脑网络的概念，这是一种连接模式，它同时代表了单个大脑皮层区域之间的信息流以及两个不同大脑区域之间的关系。通过对26对玩迭代囚徒困境的个体进行EEG扫描，构建了超脑网络，并对其进行了图形分析，揭示了在决策阶段预测非合作互动的可能性。两个背叛者的超脑网络比合作或针锋相对的夫妇有更少的脑间联系和更高的整体模块性-即形成两个独立子图的趋势。通过评估超脑网络中连接模式的变化，可以提前“读取”背叛的决定。
英文摘要：
Understanding the neural mechanisms responsible for human social interactions is difficult, since the brain activities of two or more individuals have to be examined simultaneously and correlated with the observed social patterns. We introduce the concept of hyper-brain network, a connectivity pattern representing at once the information flow among the cortical regions of a single brain as well as the relations among the areas of two distinct brains. Graph analysis of hyper-brain networks constructed from the EEG scanning of 26 couples of individuals playing the Iterated Prisoner's Dilemma reveals the possibility to predict non-cooperative interactions during the decision-making phase. The hyper-brain networks of two-defector couples have significantly less inter-brain links and overall higher modularity - i.e. the tendency to form two separate subgraphs - than couples playing cooperative or tit-for-tat strategies. The decision to defect can be "read" in advance by evaluating the changes of connectivity pattern in the hyper-brain network.
