The process of learning a new set of attitudes, values, and behaviours different from those in one's previous background and experiences.

Resocialization is a sociological concept dealing with the process of mentally and emotionally "re-training" a person so that he or she can operate in an environment other than that which he or she is accustomed to. Key examples include the process of resocializing new recruits into the military so that they can operate as soldiers (or, in other words, as members of a cohesive unit) and the reverse process, in which those who have become accustomed to such roles return to society after military discharge.
