Addressing racial bias in early childhood is crucial for fostering inclusivity and reducing social inequalities. This study examined the effectiveness of individuation training in reducing racial bias among Canadian preschool-aged children and explored how interracial contact might influence changes in children's implicit anti-Black bias. A total of 113 preschool-age children (60 females, Mage = 5.31 years) were trained to individuate Black or White faces. Results showed a significant reduction in implicit anti-Black bias following Black individuation training, whereas no significant change was observed in the White individuation training group. Additionally, factors such as interracial friendships were found to influence the reduction of bias. These findings contribute to the understanding of developmental interventions for diverse cultural contexts, with implications for early childhood education and efforts to promote social inclusivity.
