Facial and Bodily Expressions of Emotion Shape Our Willingness to Engage in an Object Handover Task Differently

Abstract

One’s emotional expressions can influence another’s cognition, attitude, and behaviour during social interactions. Yet, how one’s emotional expressions affect social interactions in a motor context has not been explored. Experiments 1 and 2 examined how facial and bodily emotions, respectively, shape one’s willingness to engage in an object handover task. Each trial started with a prompt indicating the action (give, take) and the object (knife, spoon). This was followed by a brief clip of a point-light display expressing either a facial or a bodily emotion (angry, sad, happy, neutral). Given the prompt, participants rated their willingness to engage with that person on a 7-point Likert scale. Repeated-measures ANOVA revealed a significant three-way interaction of Emotion x Action x Object on willingness ratings for facial emotions only [F(2.521, 83.179)=4.359, p<.001]. Simple main effects revealed that willingness ratings were significantly lower when giving than taking a knife when the facial emotions were angry (M=2.412, 4.103) and sad (M=2.691, 4.206). In contrast, willingness ratings were significantly lower when taking than giving a spoon for happy (M=4.397, 6.147) and neutral (M=4.191, 5.412) facial emotions. These results suggest that negative emotions (angry, sad) adversely impact one’s willingness to give someone a dangerous object, unlike positive (happy) and neutral emotions, which are perceived as less threatening. The absence of a three-way interaction for bodily emotions (p=.077) may be attributed to the task's lack of whole-body movements. Our findings show how emotional expressions shape one’s willingness to engage in a motor task.
