Human development is a multidisciplinary field of study that focuses on the processes and milestones of growth and change that individuals experience from birth through adulthood. This area of research includes exploring physical, cognitive, social, emotional, and psychological development, as well as the factors that influence and shape these areas of growth. Researchers in human development seek to better understand how individuals develop across the lifespan, and how genetics, environment, culture, and socioeconomic factors all play a role in shaping human development. It is a field that has broad implications for understanding human behavior, relationships, and overall well-being.
