Answer:
psychological moratorium.
Explanation:
A big part of identity crisis is the psychological moratorium.
During that time, a society ( parents, peers, teachers, etc ) forbid a certain individual to work on the problem and the resolution. While a young adult is put in the middle of this period, they have an opportunity to look better into society, rules, values, etc. Some people stay in the moratorium, while others find the way to break the shell and then, they find their position, place and role in the society they belong in.
