We examined the electrophysiological correlates of the processing of social exclusion and inclusion by using a modified version of the Cyberball paradigm. Exclusion was found to be associated with a significant increase in the P3 complex. The frontal-central P3a was primarily related to the affective processing of rejection, whereas the late parietal P3b was associated with its perceived intensity. The expression of P3a and negative mood did also depend on the earlier experience; earlier inclusion affected the processing of exclusion, and vice versa. In conclusion, our data indicate that the complex process of social rejection can be tracked by using event-related brain potentials.
我们使用网络球范式的修改版本，研究了社会排斥和接纳过程中的电生理相关性。发现排斥与P3复合波的显著增加有关。额中央P3a主要与拒绝的情感处理有关，而后顶叶P3b与其感知强度有关。P3a的表达和负面情绪也确实取决于早期经历；早期的接纳会影响对排斥的处理，反之亦然。总之，我们的数据表明，社会排斥的复杂过程可以通过事件相关脑电位来追踪。
