With widespread adoption of mask wearing, the 2020 Covid-19 pandemic highlighted a need for a deeper understanding of how facial feature obstruction affects emotion recognition. Here we asked participants (n=120) to identify disgusted, angry, sad, neutral, surprised, happy, and fearful emotions from faces with and without masks, and examined if recognition performance was related to their level of social competence and personality traits. Performance was reduced for all masked relative to unmasked emotions. Masks impacted recognition of expressions with diagnostic lower face features the most (disgust, anger) and those with diagnostic upper face features the least (fear, surprise). Recognition performance also varied at the individual level. Persons with higher overall social competence were better at identifying unmasked expressions, while persons with lower trait extraversion and higher trait agreeableness were better at recognizing masked expressions. These results reveal novel insights about the role of face features in emotion recognition and show that obscuring facial features affects social communication differently as a function of individual social competence and personality traits.
