The scientific study of development is important not only to psychology, but also to sociology, education, and health care. Development does not just involve the biological and physical aspects of growth, but also the cognitive and social aspects associated with development throughout life.
The study of human development is important in a number of subjects, including biology, anthropology, sociology, education, history, and psychology.
