Abstract
Background : Individuals make first impressions of others based on how they look. Facial cues trigger gender social categorisation and elicit gender stereotyping. However, it remains unclear to what extent such impressions are influenced by the perceivers’ gender identity and gender beliefs. Methods : We recruited cisgender and transgender and nonbinary (TGNB) participants (N = 195). Participants were shown three morphed faces (prototypical male versus. prototypical female versus. androgynous) and, for each target, were asked to create a sentence describing their first impression. (within-participants design). To do so, they had to choose from a list of pronouns, professions, and personality traits. Participants also reported how confident they were in their first impression and rated the gender of the targets. Results : Results showed that overall participants perceived the prototypical male target as masculine while both the prototypical female and androgynous targets were seen as feminine. Participants also felt more confident when forming an impression about the prototypical male target. Further, impressions were influenced by perceivers’ gender identity. Cisgender participants formed stronger stereotypical impressions of the prototypical male and female target than TGNB participants. In particular, cisgender participants were more likely to use masculine pronouns for the prototypical male target and more feminine pronouns for the prototypical female target, but less neutral pronouns for the androgynous target, than TGNB participants. The difference is pronoun use was mediated by cisgender participants stronger endorsement of gender binary beliefs. Conclusions : These findings provide new insights into face-based stereotyping and show the importance of considering different stereotype components and individual differences such as gender identity and beliefs.
