英文摘要	Generally, successful cooperation can only be established when the interacting persons believe that they would not be betrayed; this belief can be updated by observing the other persons' actual choices. Thus, the process of belief updating plays an important role in conditional cooperation. Using the Prisoner's Dilemma Game (PDG) with event-related potential (ERP) hyperscanning, this study investigated the dynamics of belief updating in a dyad. During the task, participants were asked if they believed that their opponent would cooperate in the next trial, and their answers functioned as a self-reported index of reciprocal belief. The results suggested that this index shows strong associations with participants' behavioral choices (cooperate/betray). At the individual level, the amplitudes of the ERP components frontal P3a and parietal P3b elicited by the decision outcome were sensitive to belief updating. At the interpersonal level, the between-subject synchronization in P3b was higher than those in the other conditions when the paired participants confirmed each other's reciprocal beliefs. Since previous studies have linked the P3b with memory updating, we suggest that a cooperative relationship is built up when the memory systems (which support belief updating) of two interacting persons reach a high level of coordination. These findings may help explain how conditional cooperation develops between strangers.
