Adolescence (Ages 12–20)
Adolescence begins with a well-defined, maturational event, puberty, and ends in a more nebulous manner. Chronologically the end of adolescence is usually defined by the attainment of age 20, but mastery of the psychological tasks of adolescence continues well into young adulthood. This phase of development is usually subdivided into four parts: preadolescence (ages 11–13), early adolescence (ages 13–15), middle adolescence (ages 15–17) and late adolescence (ages 17–19).
