Acculturation A term which is generally defined as the exchange of cultural features (traditions, values, or religious beliefs comprising the way of life) which results when groups of individuals from different cultures come into continuous direct contact, resulting in an alteration in the cultural patterns of one or both groups.
Within the context of acculturation, a person adapts to the degree of his effectiveness within the context of the new. He assumes he will leave again and return to the society of his birth. He is a fully accepted and respected member of the new yet in essence has a dual identity.
