Scientists refer to the elements of change and constancy over the life span as development. Development is defined as the orderly and sequential changes that occur with the passage of time as an organism moves from form conception to death. Human development over the life span is a process of becoming something different while remaining in some respects the same (Crandell, Crandell, & Vander Zanden, 2009, p. 4). According to the article, Toward an Experimental Ecology of Human Development, The ecology of human development is the scientific study of the progressive, mutual accommodation, throughout the life span, between a growing human organism and the changing immediate environments in which it lives, as this process is affected by relations obtaining within and between these immediate settings, as well as the larger social contexts, both formal and informal, in which the settings are embedded, p.514.
Urie Bronfenbrenner’s ecological theory is similar in some way to the elements of change in reference to the environment. Urie Bronfenbrenner proposes an ecological theory that centers on the relationship between the developing individual and the changing environmental systems (Crandell, Crandell, & Vander Zanden, 2009, p. 52). Bronfenbrenner developed five levels of influence, the microsystem, mesosystem, exosystem, macrosystem and the chronosystem.
