Most studies investigating the recognition of facial expressions have focused on static displays of intense expressions. Consequently, researchers may have underestimated the importance of motion in deciphering the subtle expressions that permeate real-life situations. In two experiments, we examined the effect of motion on perception of subtle facial expressions and tested the hypotheses that motion improves affect judgment by (a) providing denser sampling of expressions, (b) providing dynamic information, (c) facilitating configural processing, and (d) enhancing the perception of change. Participants viewed faces depicting subtle facial expressions in four modes (single-static, multi-static, dynamic, and first-last). Experiment 1 demonstrated a robust effect of motion and suggested that this effect was due to the dynamic property of the expression. Experiment 2 showed that the beneficial effect of motion may be due more specifically to its role in perception of change. Together, these experiments demonstrated the importance of motion in identifying subtle facial expressions.
大多数研究面部表情识别的实验都聚焦于强烈表情的静态展示。因此，研究人员可能低估了动态在解读现实生活中普遍存在的微妙表情方面的重要性。在两项实验中，我们研究了动态对微妙面部表情感知的影响，并检验了以下假设：动态通过（a）提供表情的更密集采样、（b）提供动态信息、（c）促进整体加工以及（d）增强变化感知来改善情感判断。参与者以四种模式观看描绘微妙面部表情的面孔（单静态、多静态、动态和首尾帧）。实验1证明了动态具有显著效果，并表明这种效果归因于表情的动态特性。实验2表明，动态的有益效果可能更具体地归因于其在变化感知中的作用。总之，这些实验证明了动态在识别微妙面部表情中的重要性。
