为了调查联合任务执行过程中形成的共享任务表征（自己与其他）的优先级，事件相关电位被记录，而参与者单独（个人条件）和与另一名参与者（联合条件）进行听觉三刺激古怪任务。参与者被要求区分频繁的标准音调和罕见的目标音调，而忽略分配给合作伙伴的行动（即不去刺激自己的任务性能）的非目标。在这两种条件下，顶叶P3b的目标引起。相反，非靶P3b仅在联合条件下观察到，此外，它伴随着正面的不去P3。这意味着合作者共享彼此的任务表征。重要的是，出现P3b和不去P3的nontargets被延迟相比，P3b的目标，这表明，共享的任务表示串行应用于刺激处理，一个人自己的表示之前，其他个人的表示。
To investigate priority of shared task representations (own vs. other) formed during joint task performance, event-related potentials were recorded while participants performed an auditory three-stimulus oddball task alone (individual condition) and with another participant (joint condition). Participants were required to discriminate between frequent standard tones and rare target tones, while ignoring nontargets assigned to a partner’s action (ie no-go stimuli for one’s own task performance). The parietal P3b was elicited for targets under both conditions. In contrast, P3b for nontargets was observed only in the joint condition, and in addition, it accompanied the frontal no-go P3. This implies that coactors share one another’s task representations. Importantly, the emergence of P3b and no-go P3 for nontargets was delayed compared with P3b for targets, suggesting that shared task representations are serially applied to the stimulus processing and that one’s own representations precede the other individual’s representations.
