当36名参与者做出愤怒、厌恶、恐惧、快乐和悲伤的面部表情时，他们的大脑活动被监控。分析每个面部姿势的脑电图α功率，并根据情绪的接近/退缩动机模型对面部状态进行分组。该模型表明，“接近”情绪与相对较大的左额叶脑活动有关，而“退缩”情绪与相对较大的右额叶脑活动有关。在双侧激活减少的情况下，戒断条件下情绪的面部姿势导致左额叶侧额叶、额叶中额叶和额叶颞中央区域的激活相对较少，但顶叶区域的激活相对较少，正如预测的那样。接近条件下的研究结果不太一致地支持接近/退出模型的预测。本文还讨论了接近/退缩模型和自主面部运动的情感诱发潜能的意义。
Brain activity was monitored while 36 participants produced facial configurations denoting anger, disgust, fear, joy, and sadness. EEG alpha power was analyzed during each facial pose, with facial conditions grouped according to the approach/withdrawal motivational model of emotion. This model suggests that "approach" emotions Lire associated with relatively greater left frontal brain activity whereas "withdrawal" emotions are associated with relatively greater right frontal brain activity. In the context of a bilateral decrease in activation, facial poses of emotions in the withdrawal condition resulted in relatively less left frontal activation in the lateral-frontal, midfrontal and frontal-temporal-central region, but not in the parietal region, as predicted. Findings in the approach condition were less consistently supportive of predictions of the approach/withdrawal model. Implications for the approach/withdrawal model and for the emotion eliciting potential of voluntary facial movement are discussed.
