The facial feedback hypothesis, that skeletal muscle feedback from facial expressions plays a causal role in regulating emotional experience and behavior, is an important part of several contemporary theories of emotion. A review of relevant research indicates that studies reporting support for this hypothesis have, without exception, used within-subjects designs and that therefore only a restricted version of the hypothesis has been tested. Also, the results of some of these studies must be questioned due to demand characteristics and other problems. It is suggested that visceral feedback may make a more direct contribution to emotional processes than facial feedback does and that the "readout" functions of facial expressions are more important than any feedback functions.
面部反馈假说认为，面部表情产生的骨骼肌反馈在调节情绪体验和行为方面起着因果作用，它是当代几种情绪理论的重要组成部分。一项相关研究综述表明，所有报告支持这一假说的研究均采用了被试内设计，因此，该假说仅经过了有限的检验。此外，由于需求特征和其他问题，其中一些研究的结果也值得质疑。有人提出，内脏反馈可能比面部反馈对情绪过程的贡献更直接，而且面部表情的“读出”功能比任何反馈功能都更重要。
