Adolescence was not considered a separate period of development until the early 20th Century when G. Stanley Hall introduced the idea that adolescence is a unique developmental period between childhood and adulthood. Puberty typically marks the beginning of this period but society has different viewpoints regarding the time when adolescence ends and adulthood begins. Hall considered the period of adolescence to end at age 24. Do you agree? How will you justify your answer? Does adolescence end when young people leave school? When they get a job?
