The subfield of communication and intergroup relations attempts to disentangle the ways in which human message exchange is influenced by, and itself affects, relations between social groups. Typically, the social groups considered are large scale groups (e.g., national, religious, ethnic groups), but similar processes can also be applied to smaller groups such as families or work groups. Specifically, the field of communication and intergroup relations considers how social interaction is changed when the interlocutors belong to (or perceive themselves as belonging to) specific social groups, and how everyday talk about groups changes perceptions and attitudes concerning those groups. The subfield also considers how broader societal messages relate to group memberships. For instance, how do media messages reflect the macrosocial position of particular groups, and do media messages influence how consumers think about group memberships and intergroup relations? Underpinning all study of intergroup communication is the belief that intergroup relations are forged, perpetuated, and modified in real-life everyday social communication.
