Cultural adaptation is a complex process of adjusting to new cultural environments while maintaining one's original identity. It involves concepts like acculturation, assimilation, and bicultural identity development. Understanding these processes helps explain how individuals and groups navigate cultural differences. Throughout history, cultural adaptation has shaped societies through migration, colonialism, and globalization. Theories like Berry's Acculturation Model and Oberg's Culture Shock Theory provide frameworks for understanding the stages and strategies individuals use when adapting to new cultures.
