Bronfenbrenner's Ecological System Theory

Introduction

  • Uri Bronfenbrenner, a psychologist, presented his ideas to the US Congress in 1964.
  • Challenged the belief that poverty was purely biological, advocating for environmental change to aid the less fortunate.

Ecological System Theory

Bronfenbrenner's theory consists of five ecological forces affecting a child's development:

1. Microsystem

  • Direct influences: family, friends.
  • Children from unfavorable backgrounds face more challenges (e.g., problematic family structures).

2. Mesosystem

  • Interconnections between the elements surrounding the child (e.g., parent-teacher relationships).
  • Conflicts in these relationships can negatively affect the child.

3. Exosystem

  • Links between social settings not directly involving the child (e.g., parent's workplace experiences).
  • Events like a parent's job loss can impact family dynamics and child development.

4. Macrosystem

  • Overarching cultural and social norms.
  • Geographic and ethnic influences affect opportunities and challenges.

5. Chronosystem

  • Evolution of the child and their environment over time.
  • Life events (e.g., parental divorce, new family members) have varied impacts depending on the child's age.

Influence and Impact

  • Bronfenbrenner's work, influenced by Lev Vygotsky and Kurt Lewin, highlighted the role of environment over genetics.
  • Contributed to the formation of the Head Start program in 1965, aiding over 35 million poor children.

Extension: Bioecological Model

  • Co-developed with Stephen Ceci.
  • Recognizes gene-environment interactions and environmental influences on genetic potential.

Key Contributions

  • Emphasized the importance of community, society, and culture in parent-child relationships.
  • Advocated for the necessity of supportive relationships for healthy child development.
  • Famous quote: "Every child needs at least one adult who is irrationally crazy about him or her."

Activity

  • Engage with the theory by mapping personal ecological influences:
    • Draw a diagram with five circles and a timeline.
    • Place yourself in the center and identify people, institutions, and forces affecting your life.
    • Reflect on how the five forces shape your experiences.
