This review of the literature on cultural adjustment is divided into four sections: the nature of cultural adjustment; acculturation as a model of cultural adjustment; psychological responses to acculturation; and a model of cultural adjustment developed by the author as a result of his immigration from Puerto Rico to the United States mainland. Language, cognitive style, identity, attitudes, and acculturation stress as experienced by Puerto Ricans are discussed. Also considered are the processes of adaptation, assimilation, integration, rejection and deculturation. The report suggests the need for more research to explain the process of cultural adjustment from a modern society to a less modern one. (JCD)
