This lecture explains culture shock as a normal process of adapting to a new cultural environment, which may involve anxiety, confusion, homesickness, frustration, and uncertainty about personal identity. Culture shock can be triggered by external factors, such as language barriers, food, climate, clothing, social expectations, and daily logistics, as well as internal factors, including separation from familiar support networks and uncertainty about personal roles and identity. Based on Oberg’s model (1960), cultural adjustment consists of four stages: honeymoon, characterized by excitement and curiosity; frustration, marked by homesickness and irritation; adjustment, when individuals gradually understand local customs and establish routines; and acceptance or adaptation, when they become comfortable functioning in the new culture. The lecture also introduces the W-curve model, which illustrates changes in satisfaction during cultural adjustment abroad and the possibility of reverse culture shock when returning to one’s home country, alongside examples of cultural differences in food, religion, education, communication, and daily social norms. To cope with culture shock, individuals are encouraged to connect with others, maintain familiar routines, learn the local language, practice patience, and set small achievable goals.
