The present research comprises six experiments that investigated racial biases in the perception of positive emotional expressions. In an initial study, we demonstrated that White participants distinguished more in their happiness ratings of Duchenne ("true") and non-Duchenne ("false") smiles on White compared with Black faces (Experiment 1). In a subsequent study we replicated this effect using a different set of stimuli and non-Black participants (Experiment 2). As predicted, this bias was not demonstrated by Black participants, who did not significantly differ in happiness ratings between smile types on White and Black faces (Experiment 3). Furthermore, in addition to happiness ratings, we demonstrated that non-Black participants were also more accurate when categorizing true versus false expressions on White compared with Black faces (Experiment 4). The final two studies provided evidence for the mediating role of attention to the eyes in intergroup emotion identification. In particular, eye tracking data indicated that White participants spent more time attending to the eyes of White than Black faces and that attention to the eyes predicted biases in happiness ratings between true and false smiles on White and Black faces (Experiment 5). Furthermore, an experimental manipulation focusing participants on the eyes of targets eliminated the effects of target race or perceptions of happiness (Experiment 6). Together, the findings provide novel evidence for racial biases in the identification of positive emotions and highlight the critical role of visual attention in this process.
A large literature has provided evidence that intergroup biases are common in facial recognition. In investigations of faces of different races, research has repeatedly demonstrated an Own Race Bias in which people are more accurate in recognizing racial ingroup compared to outgroup members. The primary goal of this research was to investigate whether participants from typically underrepresented populations in social psychological research (i.e., Blacks, South Asians, and East Asians) show biases in recognition accuracy when presented with ingroup faces and minority and majority outgroup faces. Not surprisingly, across three experiments, participants demonstrated superior recognition for faces of members of their own compared to other races. Although minority participants also demonstrated greater recognition accuracy for majority compared to minority outgroup faces, these effects were much smaller and typically nonsignificant. The implications of these findings for our understanding of basic processes in face perception, and intergroup relations, are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
