Maturity in psychology has little to do with age, but with the ability to react, cope and reason in an appropriate way for the situation. Maturity is learned through experiences and comes from healthy growth, just like a strong body. A parent gives a child food, rest and exercise for the growth of a strong body. Guidance in coping with emotional situations is what is needed to grow in maturity. The way a person deals with a crisis or makes decisions are good clues about their level of maturity.
