Acculturation

Acculturation is a term used to describe how an individual or a group from one culture interacts directly with an individual or group from a different culture. Sometimes, these two cultures may be similar, or they may be very different. Unlike culture shock, acculturation includes the ways both cultures influence each other. Also, culture shock is only focused on the individual or group who is entering a new culture. With acculturation, both cultures are looked at. Many things can be exchanged between the two cultures like language, ways of living, or foods. Acculturation is focused on the process of two cultures interacting over a long period of time, not once or twice. Cultural diffusion is different from acculturation because diffusion may occur once or twice, and means that there is an equal balance between the two things involved; with acculturation, this equal balance is not guaranteed.
History.
The term acculturation was first used by people who study anthropology. They wanted to know more about how people from different cultures interact with each other and what happens when they interact. Psychologists have also been interested in studying acculturation but are interested in the effects of acculturation on individuals. Sociologists also study acculturation and how societies change from interacting with new cultures. 
Models of acculturation.
The process of acculturation can have four outcomes: assimilation, integration, separation, and marginalization. These four outcomes are shown in the picture to the right. 
Use of acculturation in social science.
Anthropologists, Psychologists, and Sociologists all use acculturation to help explain changes that happen when cultures interact. One way of measuring levels of acculturation is through acculturative stress. This measurement helps relate acculturation to other ideas or issues and helps researchers understand what happens to individuals and groups during acculturation. Many studies have looked at acculturative stress and health of individuals. Other acculturation research studies have focused on immigrantpopulations to the United States and other minority groups.
