许多作者提出，面部表情，通过传达我们正在与之互动的人的情绪状态，影响互动行为。我们的目的是验证个人情绪的面部表情的效果有多具体（它们的效价和动作目的的相关性/特异性），以及如何执行针对同一个人的动作。此外，我们还研究了情绪对行动执行的影响是否以及如何受到被试共情态度的调节。我们使用运动学的方法来分析喂别人的模拟，其中包括使用计算机鼠标记录“喂养意愿”。演员可以表达不同的高度唤起的情绪，即快乐，厌恶，愤怒，或中性的表情。反应时间对情绪的效价和相关性/特异性之间的相互作用敏感：厌恶引起更快的反应。此外，快乐会导致进食时间变慢，达到峰值速度的时间变长，但仅限于与厌恶表情交替出现的街区。运动学配置文件描述了如何影响的具体性的情绪背景下喂养，即调制的准确性要求，发生。早期加速运动相对于中性的喂养配置文件发生时，演员表达积极的情绪（幸福）块与具体喂养的负面情绪（厌恶）。另一方面，行动的最后一部分是缓慢的，当喂养快乐相对于中立的面孔，确认增加的准确性要求和电机控制。这些运动学效应受到参与者移情态度的调节。总之，情绪的社会维度，即它们调节他人行动计划/执行的能力，严格取决于它们与行动目的的相关性和特异性。这一发现反对严格区分社会性和非社会性情绪。
Many authors have proposed that facial expressions, by conveying emotional states of the person we are interacting with, influence the interaction behavior. We aimed at verifying how specific the effect is of the facial expressions of emotions of an individual (both their valence and relevance/specificity for the purpose of the action) with respect to how the action aimed at the same individual is executed. In addition, we investigated whether and how the effects of emotions on action execution are modulated by participants' empathic attitudes. We used a kinematic approach to analyze the simulation of feeding others, which consisted of recording the 'feeding trajectory'' by using a computer mouse. Actors could express different highly arousing emotions, namely happiness, disgust, anger, or a neutral expression. Response time was sensitive to the interaction between valence and relevance/specificity of emotion: disgust caused faster response. In addition, happiness induced slower feeding time and longer time to peak velocity, but only in blocks where it alternated with expressions of disgust. The kinematic profiles described how the effect of the specificity of the emotional context for feeding, namely a modulation of accuracy requirements, occurs. An early acceleration in kinematic relative-to-neutral feeding profiles occurred when actors expressed positive emotions (happiness) in blocks with specific-to-feeding negative emotions (disgust). On the other hand, the end-part of the action was slower when feeding happy with respect to neutral faces, confirming the increase of accuracy requirements and motor control. These kinematic effects were modulated by participants' empathic attitudes. In conclusion, the social dimension of emotions, that is, their ability to modulate others' action planning/execution, strictly depends on their relevance and specificity to the purpose of the action. This finding argues against a strict distinction between social and nonsocial emotions.
