Juvenile development is the study of how children and adolescents grow and change physically, cognitively, emotionally, and socially. It explores the various factors that influence development during these formative years, including genetics, environment, and experiences. Researchers in this area may investigate topics such as cognitive development, emotional regulation, identity formation, relationships with peers and adults, and the impact of social and cultural influences on development. Understanding juvenile development is important for identifying risk factors for challenges such as mental health disorders, substance abuse, and delinquency, as well as for promoting positive outcomes and well-being in young people.
