Foster (1962) defines acculturation as the process of bringing previously separated and disconnected cultures into contact with one another. This contact must be substantial enough such that “cultural transmission” takes place (Herskovits 1950). Cultural transmission is a key concept that distinguishes acculturation from other terms that are used interchangeably, including assimilation, enculturation, and diffusion. Both Foster and Herskovits highlight the theme of cultural borrowing. The process through which cultural borrowing occurs is of central concern to sociologists and involves between-group power differentials, cultural artifacts, and group norms and values.
