Which of the following systems is not part of Brofenbrenner's Ecological Model?

In Brofenbrenner's Ecological Model, the Chronosystem is indeed a key aspect that encompasses changes over time that can affect an individual's development. However, it is important to clarify its role in relation to the systems that directly influence human interaction and development.

The Ecological Model consists of several interconnected systems that illustrate how various environmental layers impact an individual. The Mesosystem refers to the interactions between different microsystems, such as the connections between family, school, and peer groups. The Exosystem includes the broader social systems that indirectly affect the individual, such as a parent's workplace or community services. The Macrosystem represents the cultural values, customs, and laws that shape the overarching environment.

While the Chronosystem captures the dimension of time and how historical events and transitions influence development, it is distinct from the core systems that define immediate social contexts. Understanding this distinction clarifies the structure of Brofenbrenner's model and emphasizes how ecological factors are interrelated to human development.
