When you look at an angry or happy face, does it matter whose face you are looking at? In particular, does it matter what that person's race is? The experiments in the current study examined how we perceive emotional faces from different races. Eye-tracking experiments demonstrated that the race of a face profoundly affects how the face is scanned for clues about the person's emotional state. For White and Asian observers, (1) the eyes of White faces are scanned more than the eyes of Black and Asian faces, (2) the right hemi-face of White faces are scanned less than the right hemi-faces of Black and Asian faces, and (3) fixations to White faces are more random than fixations to Black or Asian faces. There were also differences in fixations to male and female faces; for example, more fixations were made to the eyes of female faces. These differences may be due to differences in structure and informativeness of the faces, and may affect the attribution of emotions. A chimeric face study (in which the right and left hemi-faces expressed different emotions) tested whether or not the race of an emotional face can moderate the strength of the left visual field bias. It was harder for observers to determine the relative emotional intensity of chimeric angry Black faces than angry White faces (i.e. response times were longer); there was no difference for happy faces. Response times for relative intensity judgments were also longer for male than female faces. Eye-tracking data were also recorded and indicated that there was also a stronger leftward fixation asymmetry for angry Black faces and happy White faces. In a visual search task, the response times to displays of angry faces increased as the number of Black faces increased, indicating a greater delay in disengagement from angry Black faces relative to angry White faces. On the other hand, response times to displays of happy faces decreased as the number of black face increased. The results are discussed in terms of perceived threat, racial stereotypes, and positive and negative evaluations of members of different races.
