The effect of racial representation on rejection sensitivity

This study examined how racial representation within small group settings impacts experiences of social rejection among people of color. Grounded in Minority Stress Theory and Rejection Sensitivity Theory, this project explored whether the presence of racial diversity can reduce expectations of discrimination and buffer against the negative effects of social exclusion. Using an experimental paradigm (Cyberball), the study tested how individuals respond to rejection in racially homogeneous vs. racially diverse groups. Self-report results indicated People of Color have experienced higher rates of race-based discrimination in their lifetimes compared to their White peers. Similarly, the study showed higher levels of race-based rejection sensitivity for People of Color. Results of the experimental portion of the study revealed that racial representation for People of Color can lead to reduced expectations and perceptions of race-based discrimination but may not have an impact on stress or subsequent avoidance or aggravation.
