The American Multiracial Face Database contains 110 faces (smiling and neutral expression poses) with mixed-race heritage and accompanying ratings of those faces by naive observers that are freely available to academic researchers. Download the face stimuli [here][1].
The faces were rated on *attractiveness*, *emotional expression*, *racial ambiguity*, *masculinity*, *racial group membership(s)*, *gender group membership(s)*, *warmth*, *competence*, *dominance*, and *trustworthiness*. The data and codebook for face ratings are available on this page.
