Describes the growth of humans throughout the lifespan, from conception to death. The scientific study of human development seeks to understand and explain how and why people change throughout life. This includes all aspects of human growth, including physical, emotional, intellectual, social, perceptual, and personality development.
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.

Piaget was one of the influential early psychologists to study the development of cognitive
