This Element offers a new theoretical model of acculturation within the general framework of cultural psychology. It is divided into four sections. First, cross-cultural and cultural orientations are contrasted. The psychology of economic migration (EARN), separate from the psychology of acculturation (LEARN), is the theme of the next section. Berry's model of acculturation preferences is discussed in section three. It serves as a contrasting reference point for the tripartite model of bicultural competencies, developed in the final section. The three interconnected components are symbols, language, and values/practices characterize both enculturation and acculturation. As a second culture learning process, acculturation is not restricted to immigration. It may take a vicarious (remote) shape in the home country. Reaching bicultural competencies and identities, in the long run, is the proposed outcome of acculturation.
