In Experiment 1 (N = 108, aged 7-12), ethnic identity was primed using Tibetan and Han names. Then negative and neutral events were applied to measure the RBEs of Tibetan children. In Experiment 2 (N = 148, aged 7-12), negative events were replaced by pain events. In Experiment 3 (N = 60, aged 7-12), Tibetan children's ethnic identity and the awareness of the wrongfulness of ethnic intergroup bias were added to examine the underlying mechanism. Results found that RBEs increased among Tibetan children aged 7-10 and decreased among those aged 11-12, Moreover, we analyzed age as a continuous variable and found that 10 years old was the inflection point in the development of RBEs in Tibetan children. Importantly, children aged 11-12 years old realized more wrongfulness of ethnic intergroup bias than children aged 7-10. The ethnic identity of Tibetan children aged 7-10 mediated the relation between age group and RBEs. And the wrongfulness of ethnic intergroup bias mediated the link between age group and RBEs in Tibetan children aged 9-12. Our study sheds light on the development of RBEs in Tibetan school-aged children and highlights the importance of identifying the appropriate timing for intervening in prejudice.
