Acculturation is the process of change in behaviour, values, and other psychological functions that occurs as a result of cultural contact. As one instance of such cultural crossing, immigrants and their offspring often face the challenges of adjusting to the mainstream Canadian culture while maintaining their heritage culture. Some immigrants experience mental switching between the two cultural identities, which may be adaptive to their unique challenges. In addition, we will discuss how acculturation may influence the basic cognitive processes, such as visual attention and perception, which influence how we see the world. Understanding this may help make the cultural transition easier. We will mainly focus on the immigrants from Asian cultures.
