Races (continent of ancestry) and within-race ethnicities of face stimuli and observers. (a) Average face for three variants of the Cambridge Face Memory Test that display: Asian faces (CFMT-Chinese24); Caucasian faces of largely Northern-European appearance (CFMT-Australian25); and Caucasian faces of more Southern-European appearance (CFMT-original20). Note the multiple physical differences in both local features and aspects of global face structure; to facilitate comparison, white boxes are identical and images matched for distance between eyes. (b) Difference-score formulae used to calculate each participant’s other-race effect (ORE) or other-ethnicity effect (OEE) score.
