在这项研究中，我们向 43 名受试者展示了六种情绪的面部表情的计算机变形动画，并要求他们评估每种表情变化率的自然程度。结果表明，表情的自然程度取决于变化的速度，四种速度的模式随情绪的不同而不同。数据的主成分分析提取了动态面部表情评估的结构，这在某些方面与之前报道的静态表情的结构不同。这些结果表明，面部表情的表征不仅包括静态属性，还包括动态属性。
In this study, we presented computer‐morphing animations of the facial expressions of six emotions to 43 subjects and asked them to evaluate the naturalness of the rate of change of each expression. The results showed that the naturalness of the expressions depended on the velocity of change, and the patterns for the four velocities differed with the emotions. Principal component analysis of the data extracted the structures that underlie the evaluation of dynamic facial expressions, which differed from previously reported structures for static expressions in some aspects. These results suggest that the representations of facial expressions include not only static but also dynamic properties.
