This article, authored by a group of scholars from various universities, provides an integrated conceptualization of ethnic and racial identity (ERI) in adolescents and young adults. It highlights the need for a metaconstruct that captures both individuals' ethnic background and their racialized experiences within a specific sociohistorical context. The authors propose a developmental timeline for ERI, emphasizing the importance of cognitive and socioemotional milestones during different stages of childhood, adolescence, and young adulthood. They discuss the role of social contexts, such as family, peers, and school, in shaping ERI and the impact of these contexts on adjustment. The article also explores the concept of nigrescence, which involves the internalization of positive and negative stereotypes, and the potential for identity self-denial in individuals who feel pressured to hide their ethnic-racial background. Finally, it suggests that ERI continues to evolve into adulthood, becoming integrated with other aspects of the self and influencing various life domains.This article, authored by a group of scholars from various universities, provides an integrated conceptualization of ethnic and racial identity (ERI) in adolescents and young adults.
