The explosive growth of individuals identifying as multiracial in the U.S. population has motivated significant interest in multiracial face perception. Interestingly, the literature reveals stunningly low rates of classifications of multiracial faces as multiracial. Five studies examined the possibility that this lack of correspondence is rooted in perceptual confusion. To test this, we utilized multidimensional scaling and discriminant function analysis to determine how participants mentally represent multiracial faces relative to Latinx and monoracial faces. Studies 1-3 establish that multiracial faces are perceptually discriminable from non-multiracial faces using three different sets of facial stimuli: Asian-White female (Study 1), Black-White female (Study 2), and Asian-White male faces (Study 3). Study 4 examined whether mental representation was further moderated by sample demographics by comparing U.S. participants sampled from Hawaii and California. Finally, Study 5 tests the consistency of mental representations across individuals and rules out potential statistical artifacts associated with group multidimensional scaling. These studies provide consistent evidence that multiracial faces are perceptually distinct from Latinx and monoracial faces, suggesting that the categorization patterns of multiracial faces observed in past research likely stem from downstream processes rather than perceptual confusability of multiracial faces.
