Adolescent development is a field of study that focuses on the physical, cognitive, emotional, and social changes that occur during the period of adolescence, typically defined as the teenage years between puberty and adulthood. Researchers in this area study various aspects of adolescent development, including identity formation, peer relationships, risk-taking behavior, and moral reasoning. They seek to understand how these changes impact adolescents' relationships with their families, peers, and communities, as well as their overall well-being and future outcomes. Adolescence is a critical period of growth and change, and understanding these processes can help inform interventions and policies aimed at supporting young people during this transition.
