人脸感知受情绪效价和社会关联的调节，但它们之间的相互作用很少被研究。记录不同社会关联程度的快乐、中性和愤怒面部表情的事件相关脑电位（ERP）。为了完成社会预期任务，通过呈现两个特定参与者的面孔作为未来的互动伙伴（社会相关）来操纵相关性，而另外两个面孔参与者保持不相关。在进一步的控制任务中，所有的刺激都没有具体的相关说明（被动观看）。四名演员（2名女性，来自KDEF）的面部刺激随机呈现给15至26名参与者（16名女性）。结果显示，与中性面部表情相比，情绪性面部表情的N170、早期后极性（EPN）和晚期正电位（LPP）增强。特别有趣的是，人脸处理随着实验任务的变化而变化。尽管P1和EPN的任务效应与指示相关性无关，但LPP的振幅受到情绪面部表情和相关性操作的调节。LPP对于预期未来互动伙伴的快乐面部表情特别增强。这强调了社会关联可以在视觉处理的早期阶段就影响面部处理。这些发现在动机注意和面孔加工理论的框架内进行了讨论。
Human face perception is modulated by both emotional valence and social relevance, but their interaction has rarely been examined. Event-related brain potentials (ERP) to happy, neutral, and angry facial expressions with different degrees of social relevance were recorded. To implement a social anticipation task, relevance was manipulated by presenting faces of two specific actors as future interaction partners (socially relevant), whereas two other face actors remained non-relevant. In a further control task all stimuli were presented without specific relevance instructions (passive viewing). Face stimuli of four actors (2 women, from the KDEF) were randomly presented for 1s to 26 participants (16 female). Results showed an augmented N170, early posterior negativity (EPN), and late positive potential (LPP) for emotional in contrast to neutral facial expressions. Of particular interest, face processing varied as a function of experimental tasks. Whereas task effects were observed for P1 and EPN regardless of instructed relevance, LPP amplitudes were modulated by emotional facial expression and relevance manipulation. The LPP was specifically enhanced for happy facial expressions of the anticipated future interaction partners. This underscores that social relevance can impact face processing already at an early stage of visual processing. These findings are discussed within the framework of motivated attention and face processing theories.
