Ecological systems theory is a broad term used to capture the theoretical contributions of developmental psychologist Urie Bronfenbrenner. [1] Bronfenbrenner developed the foundations of the theory throughout his career, [2] published a major statement of the theory in American Psychologist, [3] articulated it in a series of propositions and hypotheses in his most cited book, The Ecology of ...
Bronfenbrenner was born in Moscow on April 29, 1917, [8] to Russian Jewish parents, the pathologist Alexander Bronfenbrenner and Eugenie Kamenetski. [9] When he was six, his family moved to the United States, first to Pittsburgh, Pennsylvania, and then a year later to rural New York State. [10]
Processes, per Bronfenbrenner, explain the connection between some aspect of the context or some aspect of the individual and an outcome of interest. The full, revised theory deals with the interaction among processes, person, context and time, and is labeled the Process–Person–Context–Time model (PPCT).
Ecological systems theory, originally formulated by Urie Bronfenbrenner, specifies four types of nested environmental systems, with bi-directional influences within and between the systems. The four systems are microsystem, mesosystem, exosystem, and macrosystem. Each system contains roles, norms and rules that can powerfully shape development.
The history of bioecological systems theory is divided into two periods. The first period resulted in the publication of Bronfenbrenner's theory of ecological systems theory, titled The Ecology of Human Development, in 1979. [16] Bronfenbrenner described the second period as a time of criticism and evaluation of his original work. [17]
According to this theory, life span development has multiple trajectories (positive, negative, stable) and causes (biological, psychological, social, and cultural). Individual variation is a hallmark of this theory – not all individuals develop and age at the same rate and in the same manner. [15] Bronfenbrenner's ecological theory
