Adolescent psychology is the study of the mental, emotional, and social development of individuals aged approximately 10 to 19 years. This field examines how adolescents navigate the challenges of growing up, including identity formation, peer relationships, and the transition to adulthood. It also explores the impact of biological changes, such as puberty, on behavior and mental health. Researchers in adolescent psychology focus on various factors that influence development, including family dynamics, cultural background, and societal expectations. Understanding these elements helps in addressing issues like depression, anxiety, and risk-taking behaviors that are common during this stage of life.
