Acculturation is the process of bidirectional change that occurs when two ethnolinguistic groups come in sustained contact with one another. Acculturation usually occurs between groups of unequal power, status, and demographic background. At stake for the unity of multilingual states are intergroup relations between language minorities and majorities that yield harmonious to conflictual outcomes. The Interactive Acculturation Model (IAM) is adapted to intergroup relations between language communities in four parts. The first part of the model provides an overview of the ethnolinguistic vitality framework accounting for the strength of minority/majority language communities as they struggle to gain the institutional support they need to develop as distinctive and thriving language communities. The second part of the IAM offers an analysis of the pluralist, civic, assimilationist, and exclusionist ideologies that underpin language policies regulating the co-existence of minority/majority language communities. The third part examines the acculturation orientations endorsed by majority and minority language group speakers. The fourth part of the IAM proposes that the interaction of majority and minority acculturation orientations yield intergroup communication outcomes that may range from harmonious, problematic, to conflictual. Taken together, the IAM model offers a conceptual tool for analyzing the fate of linguistic minorities as they seek to survive in the dominant majority group environments of post-modern globalizing states.
