The Ecological Systems Theory, also known as Human Ecology Theory, posits that human development is influenced by various environmental systems. Developed by psychologist Urie Bronfenbrenner, this theory helps explain why individuals behave differently in different settings, such as at home, school, or work. The theory outlines five environmental systems: the microsystem, mesosystem, exosystem, macrosystem, and chronosystem. 1. **The Microsystem**: This is the direct environment where individuals have immediate social interactions with family, friends, classmates, teachers, and neighbors. 2. **The Mesosystem**: It involves the relationships between different microsystems, such as how a child's family experience can influence their school experience. 3. **The Exosystem**: This system links contexts where an individual is not actively involved but has a significant impact, such as a parent's absence due to work affecting the child's relationship with the other parent. 4. **The Macrosystem**: This refers to the cultural and socioeconomic context, including factors like ethnicity, race, and socioeconomic status. 5. **The Chronosystem**: This system includes transitions and shifts in one's lifespan, such as major life events like divorce, which can affect both the couple's relationship and the children's behavior. The Ecological Systems Theory, published in 1979, has significantly influenced psychological research and has become a foundational concept in understanding the complex interplay of environmental factors in human development.The Ecological Systems Theory, also known as Human Ecology Theory, posits that human development is influenced by various environmental systems.
