Lewis 1 , Ruby Mendenhall 2 , Ashley Ojiemwen 3 , Merin Thomas 2 , Cameron Riopelle 4 , Stacy Anne Harwood 5 , and Margaret Browne Huntt 2 Abstract This study applied critical race theory to explore the racial microaggression experiences of students of color (i.e., African American, Asian American, Latinx, and Multiracial students) at a historically White university. Using quantitative and qualitative data from an online survey (N = 1,710), we explored the relationship between the frequency of racial microaggressions and sense of belonging using multiple regression analysis. In addition, we analyzed qualitative open-ended responses to better understand students’ perceptions about how the racial microaggressions they experienced affected their sense of belonging. The findings indicated that African American students reported experiencing a significantly greater frequency of racial microaggressions than Asian American, Latinx, and Multiracial students. In addition, students who reported a greater frequency of racial microaggressions also reported lower sense of belonging. We highlight implications for future research on students of color at historically White universities.
