Maturation: Maturation is the process of learning to cope and react in an emotionally appropriate way. It does not necessarily happen along with aging or physical growth, but is a part of growth and development. A situation a person must deal with at a young age prepares them for the next and so on into adulthood. Maturation does not stop when physical growth ends - it continues through adulthood. An adult who loses a parent, for instance, learns to cope with a new emotional situation that will affect the way he or she deals with situations that follow.
