The facial feedback hypothesis suggests that facial expressions are either necessary or sufficient to produce emotional experience. Researchers have noted that the ideal test of the necessity aspect of this hypothesis would be an evaluation of emotional experience in a patient suffering from a bilateral facial paralysis; however, this condition is rare and no such report has been documented. We examined the role of facial expressions in the determination of emotion by studying a patient (F.P.) suffering from a bilateral facial paralysis. Despite her inability to convey emotions through facial expressions, F.P. reported normal emotional experience. When F.P. viewed emotionally evocative slides her reactions were not dampened relative to the normative sample. F.P. retained her ability to detect, discriminate, and image emotional expressions. These findings are not consistent with theories stating that feedback from an active face is necessary to experience emotion, or to process emotional facial expressions.
面部反馈假说认为，面部表情对于产生情感体验要么是必要的，要么是充分的。研究人员指出，对这一假说必要性方面的理想测试将是评估一位双侧面部瘫痪患者的情感体验；然而，这种情况很罕见，尚无此类报告被记录。我们通过研究一位双侧面部瘫痪患者（F.P.）来检验面部表情在情感判定中的作用。尽管F.P.无法通过面部表情传达情感，但她报告称情感体验正常。当F.P.观看能唤起情感的幻灯片时，她的反应与正常样本相比并未减弱。F.P.保留了检测、辨别和想象情感表情的能力。这些发现与那些认为主动面部的反馈对于体验情感或处理情感面部表情是必要的理论不一致。
