Answer:
entry into a total institution
Step-by-step explanation:
Resocialization is the process when former beliefs, attitudes of an individual are destroyed to reshape him.
Resocialization occurs mainly in total institutions, like prisons or military camps where people's personalities are manipulated in artificial settings so they can produce "new individuals".
The key of total institutions is that they will separate the subjects from the rest of society, and new values will be learned as part of norms of that institution and the person will change to function to the demands of that norms with attitudes and skills that were unknown to them.
The changing of personality will often employ rewards and punishments.
In the end, individuals will often turn unable to take decisions by themselves, and will most likely never be fit again fot the life outside the total institution with the rest of society.
