Urie Bronfenbrenner was a Russian-American developmental psychologist who developed the Ecological Systems Theory, which examines a child's development within the context of the different environmental systems they interact with. These systems include the microsystem of immediate relationships, the mesosystem of interactions between microsystems, the exosystem of external social settings, the macrosystem of cultural values, and the chronosystem of environmental events over a person's lifetime. Bronfenbrenner's theory focused on how these nested environmental systems influence a child's development.
