Childhood development is a field of study that focuses on the physical, cognitive, social, emotional, and behavioral development of children from infancy through adolescence. Researchers in this area investigate the factors that impact a child's development, including genetics, environment, parenting styles, early childhood education, and cultural influences. The goal of childhood development research is to better understand how children grow and change over time, as well as to identify ways to support and promote healthy development in children. Studies in this area often involve longitudinal research, observation, and experimentation to track developmental milestones and identify potential risk factors for developmental delays or disorders.
