We examined how the recognition of facial emotion was influenced by manipulation of both spatial and temporal properties of 3-D point-light displays of facial motion. We started with the measurement of 3-D position of multiple locations on the face during posed expressions of anger, happiness, sadness, and surprise, and then manipulated the spatial and temporal properties of the measurements to obtain new versions of the movements. In two experiments, we examined recognition of these original and modified facial expressions: in experiment 1, we manipulated the spatial properties of the facial movement, and in experiment 2 we manipulated the temporal properties. The results of experiment 1 showed that exaggeration of facial expressions relative to a fixed neutral expression resulted in enhanced ratings of the intensity of that emotion. The results of experiment 2 showed that changing the duration of an expression had a small effect on ratings of emotional intensity, with a trend for expressions with shorter durations to have lower ratings of intensity. The results are discussed within the context of theories of encoding as related to caricature and emotion.
我们研究了面部运动的三维点光显示的空间和时间属性的操纵如何影响面部情绪的识别。我们首先测量了在愤怒、快乐、悲伤和惊讶的表情中面部多个位置的三维位置，然后操纵这些测量的空间和时间属性以获得运动的新版本。在两个实验中，我们研究了对这些原始和修改后的面部表情的识别：在实验1中，我们操纵了面部运动的空间属性，在实验2中我们操纵了时间属性。实验1的结果表明，相对于固定的中性表情对面部表情进行夸张会导致该情绪强度评分的提高。实验2的结果表明，改变表情的持续时间对情绪强度评分有较小影响，持续时间较短的表情有强度评分较低的趋势。在与漫画和情绪相关的编码理论背景下对结果进行了讨论。
