Bronfenbrenner further developed the model by adding the chronosystem, which refers to how the person and environments change over time. He also placed a greater emphasis on processes and the role of the biological person. The Process–Person–Context–Time Model (PPCT) has since become the bedrock of the bioecological model.
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).

[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 ...
Renn used Urie Bronfenbrenner's Person, Process, Context, Time (PPCT) model to determine which ecological factors were most influential on biracial and multiracial identity development. [25] Three dominant ecological factors emerged from Renn's research: physical appearance, cultural knowledge, and peer culture.
Bronfenbrenner further developed the model by adding the chronosystem and placing a greater emphasis on processes and the role of the biological person. The Process-Person-Context-Time Model (PPCT) has since become the bedrock of the bioecological model, which examines human development across the lifespan. PPCT includes four concepts.
Urie Bronfenbrenner (April 29, 1917, Moscow [1] – September 25, 2005) was a Russian-born American psychologist best known for using a contextual framework to better understand human development. [2]
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. Bronfenbrenner's ecological theory is an environmental system theory and social ecological model which focuses on five environmental systems:
Past psychologists such as Urie Bronfenbrenner, popularized the belief that social factors play a role in developing illnesses and behaviors. Simply, Engel used Bronfenbrenner's research as a column of his biopsychosocial model and framed this model to display health at the center of social, psychological, and biological aspects.
