In this experiment, we used the adaptation paradigm to explore the facial ethnical and emotional processing bias of Han Chinese residents in the Xinjiang Uygur Autonomous Region. Results show that: (1) Although ethnicity was a task-independent variable, participants were able to distinguish different ethnicities, and the cross-race effects of faces were replicated on the ethnic dimension; (2) The Han subjects were more sensitive to the sad emotion of Han faces and the happy emotion of Uygur faces; (3) For Han subjects, Uyghur faces had more weight in face processing.
