ABSTRACT
When categorising a face based on race, people respond faster to other-race faces than own-race faces [Other-Race Categorisation Advantage (ORCA)]. Five experiments were conducted to examine the ORCA in Chinese participants in race categorisation tasks. Participants classified a face either as Chinese vs. non-Chinese (binary response) or as Caucasian, Indian, or Chinese (ternary response). Experiments 1A and 1B replicated the ORCA with Chinese vs. Caucasian and Chinese vs. Indian faces, respectively, in a binary-response task. Experiments 2A/2B and 3 presented faces of all three races in the ternary- and binary-response tasks. Task type was manipulated between and within participants in Experiments 2A/2B and 3, respectively. The typical ORCA occurred in the binary-response task, but did not consistently so in the ternary-response task. These results indicate that neither the race-feature hypothesis [Levin, D. T. 1996. Classifying faces by race: The structure of face categories. Journal of Experimental Psychology: Learning, Memory, and Cognition, 22(6), 1364–1382] nor the differential processing hypothesis [Zhao, L., & Bentin, S. 2011. The role of features and configural processing in face-race classification. Vision Research, 51(23-24), 2462–2470] could fully account for the ORCA observed in the ternary-response task.

1 We first conducted a 2 (Face Gender: male vs. female) × 2 (Face Race: Chinese vs. Caucasian) × 2 (Participant Gender) repeated-measures ANOVA for mean RTs of Experiment 1A. The main effects of face gender was significant, F(1,18) = 14.02, MSE = 167.82, p = .001, = .42. The main effects of face race was also significant, F(1,18) = 13.68, MSE = 305.94, p = .002, = .43. However, there was a significant interaction of face gender and face race, F(1,18) = 5.56, MSE = 107.57, p = .03, = .23. The main effect of participant gender was not significant, F(1,18) = .75, MSE = 14431.43, p = .398, = .04. The interactions of participant gender and other factors failed to reach the significance level: the interaction of face gender and participant gender, F(1,18) = .46, MSE = 167.82, p = .50, = .02; the interaction of face race and participant gender, F(1,18) = .33, MSE = 305.94, p = .56, = .01; the interaction of face gender, face race, and participant gender, F(1,18) = .02, MSE = 107.57, p = .89, = .001.
