Bronfenbrenner (Urie Bronfenbrenner)

Urie Bronfenbrenner was a psychologist known for his ecological systems theory, which explains how a person's development is shaped by different environmental layers. He described five systems: the microsystem (immediate environment like family and school), the mesosystem (interactions between these settings), the exosystem (indirect influences like parents’ workplaces), the macrosystem (cultural and societal norms), and the chronosystem (changes over time). These interconnected layers influence a person’s growth, behaviors, and experiences, emphasizing that development is affected by multiple levels of environment working together over time.
