Many current and past theories of social categorization acknowledge and even underline the critical role that visual processing plays in intergroup misperceptions and biases, yet research that directly measures or manipulates these processes is limited. In the present paper, we reviewed the current literature on visual attention to own and other group faces. First, we explored the development of preferential attention in face processing. Next, we examined these processes in adults and show different patterns of attention for own and other group faces. Although we briefly consider cross-cultural variations, the focus of this review is on within-culture differences in visual attention. In particular, we explore preferential attention to specific features on own versus other group faces and to their overall faces. We also discuss potential determinants for differential attention such as experience, threat, individuation and a desire to know ingroups, and liking. Finally, we explore the implications of differential attention to own and other groups. These consequences range from reduced recognition of other group faces, to impaired identification of emotional expressions, to impeded interaction intentions, and to increased discrimination. Together our analyses provide strong evidence for differences in attention to the faces and eyes of own versus other group members and their role in intergroup biases.
