ecological systems theory

an evolving body of theory and research concerned with the processes and conditions that govern the course of human development in the actual environments in which human beings live. Originally focused on the environment as a context for child development (in terms of nested systems ranging from micro- to macro-), the theory is now known as the bioecological model, denoting a broader conception of human development as a process that is affected, across the lifespan and across successive generations, by both environmental context and individual biopsychological characteristics. See also chronosystem; ecosystemic approach; exosystem; macrosystem; mesosystem. [originally conceptualized by Urie Bronfenbrenner]
