We use a Brunswikian lens model approach to address the kinds of emotions powerful people feel and express and how emotional expressions influence power perception. For instance, when a target expresses anger, happiness, or pride, the target is perceived as more powerful. Conversely, when a target expresses shame or sadness, the target is perceived as less powerful. Yet, one might wonder whether these inferences are correct and lead to accurate assessments of people’s power. In other words, can emotional expressions be used to infer how powerful people are? Powerful people tend to feel and show different emotions than powerless people. High-power individuals tend to feel more positive emotions and they are also less inhibited when it comes to expressing anger. Therefore, certain emotional expressions can be used as cues to make inferences about how powerful people are. The aim of this chapter is to understand how emotional expressions impact power perceptions and to investigate which emotional expressions can be used as valid cues to assess how much power a person has.
