Shaping children's racial bias through interpersonal movement

The early emergence of racial biases points to the urgent need to understand how interpersonal experiences might shape them. We examined whether interpersonal movement shapes racial biases among 4- to 6-year-old Chinese children who had no prior contact with Black people. In Experiment 1 (N = 134), children played a musical game, moving either in or out of synchrony with a Chinese or Black adult. In Experiment 2 (N = 30), children were merely exposed to a Black adult. Across the two experiments, we found that synchronous movement increased children's feeling of social closeness toward their movement partner to a greater extent than asynchronous movement regardless of the partner's race. After moving in or out of synchrony with the Chinese adult, synchrony selectively increased children's explicit positive pro-own-race bias. However, after moving in or out of synchrony with the Black adult, both movement styles reduced explicit anti-other-race bias. Experiment 2 ruled out mere exposure to an other-race person as a driving factor for these effects. Our results suggest that musical engagement may be a promising intervention for reducing negative intergroup biases.
