Adolescence is a turbulent period to live through. Marking the transition from the world of childhood to adult life, the adolescent faces many challenges and opportunities, including puberty, cognitive changes, forming their own identity, relating to often conflicting demands from parents and peers, and negotiating first romantic relationships. Adolescence: A Very Short Introduction provides a guide to the classical research that has informed our knowledge on adolescence, as well as the results of modern research into the contemporary adolescent experience. It also examines a number of aspects of adolescence, including the cultural and historical context, the biological changes to the adolescent brain, and the controversies that adolescence brings.
