This document discusses the concept of culture shock, describing the 5 stages of culture shock as identified by anthropologist Kalervo Oberg. The stages are: 1) Honeymoon Phase, where newcomers are excited about everything; 2) Emptiness/Rejection Phase, where problems arise and people start to miss home; 3) Conformist Phase, where people start to accept and engage with their new culture; 4) Assimilation/Complete Phase after about a year, where people feel comfortable and confident in their new environment; and 5) Reverse Culture Shock upon returning home after time abroad as they adjust to changes back home.
