, people will initially have (1) a honeymoon period, followed by (2) a transition period, that is, cultural shock. Over time people will begin to (3) adapt (the dotted line depicted some people hated by new cultures instead), before in some cases (4) returning to their own places and re-adapting to the old culture.
Kalervo Oberg first proposed his model of cultural adjustment in a talk to the Women's Club of Rio de Janeiro in 1954.
Honeymoon During this period, the differences between the old and new culture are seen in a romantic light. For example, in moving to a new country, an individual might love the new food, the pace of life, and the locals' habits. During the first few weeks, most people are fascinated by the new culture. They associate with nationals who speak their language, and who are polite to the foreigners. Like most
honeymoon periods, this stage eventually ends.
Negotiation After some time (usually around three months, depending on the individual), differences between the old and new culture become apparent and may create
anxiety. Excitement may eventually give way to unpleasant feelings of frustration and anger as one continues to experience unfavorable events that may be perceived as strange and offensive to one's cultural attitude. Language barriers, stark differences in public hygiene, traffic safety, food accessibility and quality may heighten the sense of disconnection from the surroundings. While being transferred into a different environment puts special pressure on communication skills, there are practical difficulties to overcome, such as
circadian rhythm disruption that often leads to
insomnia and daylight drowsiness; adaptation of
gut flora to different
bacteria levels and concentrations in food and water; difficulty in seeking treatment for illness, as medicines may have different names from the native country's and the same
active ingredients might be hard to recognize. Still, the most important change in the period is communication: People adjusting to a new culture often feel
lonely and homesick because they are not yet used to the new environment and meet people with whom they are not familiar every day. The language barrier may become a major obstacle in creating new relationships: special attention must be paid to one's and others' culture-specific
body language signs, linguistic faux pas, conversation tone, linguistic nuances and customs, and
false friends. Such cultural adjustments may also cause a sense of identity confusion as individuals try to balance their original cultural identity with the pressures of assimilating into a new one. Having to preserve one's identity while adhering to new standards may be psychologically taxing, which can result in emotional tiredness or even despair. In the case of students studying abroad, some develop additional symptoms of loneliness that ultimately affect their lifestyles as a whole. Due to the strain of living in a different country without parental support, international students often feel anxious and feel more pressure while adjusting to new cultures—even more so when the cultural distances are wide, as patterns of
logic and
speech are different and a special emphasis is put on
rhetoric.
Adjustment Again, after some time (usually 6 to 12 months), one grows accustomed to the new culture and develops routines. One knows what to expect in most situations and the host country no longer feels all that new. One becomes concerned with basic living again, and things become more "normal". One starts to develop problem-solving skills for dealing with the culture and begins to accept the culture's ways with a
positive attitude. The culture begins to make sense, and negative reactions and responses to the culture are reduced.
Adaptation In the mastery stage individuals are able to participate fully and comfortably in the host culture. Mastery does not mean total conversion; people often keep many traits from their earlier culture, such as accents and languages. It is often referred to as the
bicultural stage. ==Development==
