Developmental psychology is the scientific study of
how and why human beings change over the course of their life. Originally
concerned with infants and children, the field has expanded to include
adolescence, adult development, aging, and the entire lifespan. Developmental
psychologists aim to explain how thinking, feeling, and behaviors change
throughout life. This field examines change across three major dimensions:
physical development, cognitive development, and socioemotional development.
Within these three dimensions are a broad range of topics including motor
skills, executive functions, moral understanding, language acquisition, social
change, personality, emotional development, self-concept, and identity
formation. Developmental psychology examines the influences of nature and
nurture on the process of human development, and processes of change in context
across time. Many researchers are interested in the interactions among personal
characteristics, the individual’s behavior, and environmental factors,
including the social context and the built environment. Ongoing debates in
regards to developmental psychology include biological essentialism vs.
neuroplasticity and stages of development vs. dynamic systems of development.
Psychological development, the development of human beings’ cognitive,
emotional, intellectual, and social capabilities and functioning over the
course of the life span, from infancy through old age.
