Does facial redness really affect emotion perception? Evidence for limited generalisability of effects of facial redness on emotion perception in a large sample

We conducted a preregistered study (N = 609) to conceptually replicate and extend prior research regarding the effects of facial redness on emotion perception. In a within-subjects design, participants saw emotion faces (anger, happiness, fear, neutral) of a random female and a random male target with default facial colouration and increased facial redness and were asked to simultaneously rate the intensity of six emotions (happiness, surprise, sadness, fear, disgust, anger) for each emotion face. The emotion intensity was rated higher, when the emotion face and the rated emotion matched than when the emotion face and the rated emotion did not match. However, increased facial redness did not influence the intensity of the rated emotion. The results of this conceptual replication limit the generalisability of previous findings, challenge the assumption that facial redness is used as a cue to infer emotions, and point to the necessity to develop a more nuanced theoretical account of contextual boundaries.
