Two experiments were run to examine the effects of dynamic displays of facial expressions of emotions on time judgments. The participants were given a temporal bisection task with emotional facial expressions presented in a dynamic or a static display. Two emotional facial expressions and a neutral expression were tested and compared. Each of the emotional expressions had the same affective valence (unpleasant), but one was high-arousing (expressing anger) and the other low-arousing (expressing sadness). Our results showed that time judgments are highly sensitive to movements in facial expressions and the emotions expressed. Indeed, longer perceived durations were found in response to the dynamic faces and the high-arousing emotional expressions compared to the static faces and low-arousing expressions. In addition, the facial movements amplified the effect of emotions on time perception. Dynamic facial expressions are thus interesting tools for examining variations in temporal judgments in different social contexts.
进行了两项实验来检验情绪面部表情的动态展示对时间判断的影响。参与者被给予一项时间二等分任务，其中情绪面部表情以动态或静态展示呈现。测试并比较了两种情绪面部表情和一种中性表情。每种情绪表情具有相同的情感效价（不愉快），但一种是高唤醒度的（表达愤怒），另一种是低唤醒度的（表达悲伤）。我们的结果表明，时间判断对面部表情的动作和所表达的情绪高度敏感。事实上，与静态面部和低唤醒度表情相比，对动态面部和高唤醒度情绪表情的反应中发现了更长的感知持续时间。此外，面部动作放大了情绪对时间感知的影响。因此，动态面部表情是用于检验不同社会背景下时间判断变化的有趣工具。
