Acculturation is a process in which members of one cultural group adopt the beliefs and behaviors of another group. Although acculturation is usually in the direction of a minority group adopting habits and language patterns of the dominant group, accult uration can be reciprocal--that is, the dominant group also adopts patterns typical of the minority group. Assimilation of one cultural group into another may be evidenced by changes in language preference, adoption of common attitudes and values, members hip in common social groups and institutions, and loss of separate political or ethnic identification.
