Globalization is making interethnic communication an increasingly widespread issue. The reduction of actual and psychological distances due to migratory flows and media communication increases contact opportunities between individuals from different ethnic groups. Communication between members belonging to different ethnic groups can also be considered a challenge as it brings in more general intergroup controversies. Ethnicity affects both verbal and nonverbal communication at different intensity levels. For example, using verbal communication, interethnic conflict may emerge through the use of hate speech, and—at a lower intensity level—may also emerge by the subtle use of pronouns (e.g., avoiding the use of “we” to exclude members of other groups). Similarly, in nonverbal communication, interethnic conflicts may strongly be evident in explicit exclusion behaviors, but also in subtler cues such as by enhancing spatial distance from persons belonging to other groups. Ethnic identities and their implications are also evident in and influenced by mass media narratives, which mirror, establish, and perpetuate inequalities and discrimination. Interethnic communication is therefore a challenge and an opportunity to understand and to improve relationships between ethnic groups.
