I actually teach a German course to a group of recognized refugees, including Syrians and Eritreans.<p>From what I&#x27;ve seen, the ability to handle the culture shock varies wildly from person to person and is strongly correlated with age.<p>The younger a person is, the better they adapt to the new situation. IMO the two main reasons for this are that younger people are more flexible intellectually, and that a significant number of them (but not all!) have had more exposure to other cultures due to the Internet.<p>I also get the impression that frustration and language skill are correlated. The ability to learn a new language is obviously also correlated with age and educational history.<p>Note that there are outliers in all directions, but these are the trends that I observed.
