Humans flexibly adapt expressions of emotional messages when interacting with others. However, detailed information on how specific parts of the face and hands move in socio-emotional contexts is missing. We identified individual gesture and facial movements (through automated face tracking) of = 80 participants in the UK, produced while watching amusing, fearful, or neutral movie scenes either alone or with a social partner. Amusing and fearful scenes, more so than neutral scenes, led to an overall increase in facial and gesture movements, confirming emotional responding. Furthermore, social context facilitated movements in the lower instead of upper facial areas, as well as gesture use. These findings highlight emotional signaling components that likely underwent selection for communication, a result we discuss in comparison with the nonhuman primate literature. To facilitate ecologically valid and cross-cultural comparisons on human emotion communication, we additionally offer a new stimuli database of the recorded naturalistic facial expressions.
人类在与他人互动时会灵活地调整情感信息的表达。然而，关于面部和手部的特定部位在社会情感情境中如何运动的详细信息却尚付阙如。我们通过自动面部追踪识别了英国80名参与者在独自观看或与社交伙伴一起观看有趣、恐怖或中性电影场景时的个体手势和面部动作。与中性场景相比，有趣和恐怖场景更能导致面部和手势动作的总体增加，证实了情感反应。此外，社会情境促进了面部下部而非上部区域的动作以及手势的使用。这些发现凸显了可能经过交流选择的情感信号成分，我们将这一结果与非人类灵长类动物文献进行了比较讨论。为便于对人类情感交流进行生态有效且跨文化的比较，我们还提供了一个记录自然主义面部表情的新刺激数据库。
