Within the discipline of communication, the concept of “cultural identities” has captivated, fascinated, and received sustained attention from scholars of communication and culture over time. Like the concept of “culture,” which is varied, complex, and at times contested, the study of cultural identity has been approached from diverse lenses, whether theoretically, methodologically, or ontologically. In one sense, cultural identity can be understood as the experience, enactment, and negotiation of dynamic social identifications by group members within particular settings. As an individual identifies with—or desires acceptance into—multiple groups, people tend to experience, enact, or negotiate not just one cultural identity at a time but often multiple cultural identities at once. Further, how one experiences her/his intersecting cultural identities with others can vary from context to context depending on the setting, the issue at hand, the people involved, etc. Not surprisingly, intercultural communication scholars have contributed quite a number of theories concerning cultural identities within communication interactions: co-cultural theory, cultural contract theory, and identity negotiation theory, to name a few. In addition, intercultural communication scholars have offered rich cases that examine dynamic enactments, negotiations, or contestations of cultural identities across important contexts such as race, media, and globalization. Ultimately, the study of cultural identities offers rich understandings for both oneself and others. As the world that we inhabit is becoming increasingly diverse, the study of cultural identities will continue to gain traction within the communication discipline and beyond.
