Tien Ung, Susan Harris O'Connor and Raymond Pillidge introduce a model that aims to explain the development of racial identity in transracially adopted people. The nature and process of racial identity development is examined through a transactional lens, using ecology theory as a conceptual framework. The authors propose that racial identity is a multi-dimensional construct that evolves as a result of an interactive and reciprocal relationship between a person and his or her social, cultural and political environment. In this model, racial identity is comprised of five dimensions: genetic racial identity, imposed racial identity, cognitive racial identity, visual racial identity and feeling racial identity (Harris O'Connor, 1999). The authors draw on selected content from the published personal narratives of adults who were transracially adopted as children to clarify the meaning of each construct, and to illustrate how the constructs may manifest in the experiences and lives of transracially adopted people.
