向参与者展示 P. Ekman 和 W.V. 作品中符合 FACS 标准的静态或动画头像。 Friesen (1978)，并要求识别面部所表现出的情绪。在第一个版本的面部中，无论刺激类型如何，幸福、悲伤和惊讶的识别率都很高（80% 或更高），而愤怒和厌恶的识别率较低。当观看静态图像时，中性面孔无法被很好地识别，但当观看动画时，中性面孔的识别率明显更高。在第二个实验中，为了“调整”中性和愤怒的面孔而做出的小改变只取得了部分成功。大约一半的人认出了这张静态的愤怒面孔；认识动画版的人要少得多；大多数人错误地识别了中性面孔，无论是静态的还是动画的。更令人惊讶的是，在第二次实验中，静态和动画面孔的幸福、悲伤和惊讶的识别率显着下降。这可能是由于第一次和第二次实验之间刺激的呈现方式发生了变化。这些结果表明，人们对头像面部呈现中看似无害的微小变化很敏感
Participants were shown static or animated versions of a FACS-compliant avatar face in the work of P. Ekman and W.V. Friesen (1978), and asked to identify the emotion that the face was displaying. In the first version of the face, happiness, sadness, and surprise were all recognized at high rates (80% or more) whatever the stimulus type, while anger and disgust had low recognition rates. The neutral face was not well recognized when viewed as a static image, but was recognized significantly more often when animated. In a second experiment, small changes made to "tweak" the neutral and angry faces were only partially successful. About half the people recognized the static angry face; far fewer recognized the animated version; and most people wrongly identified the neutral face, both in its static and its animated version. More surprisingly, the recognition rates for happiness, sadness and surprise dropped significantly during the second experiment, for both the static and the animated faces. This may be due to changes in the way the stimuli were presented between the first and the second experiment. These results suggest that people are sensitive to small, seemingly innocuous changes in the presentation of avatar faces
