The Ecological System Theory

The Ecological System Theory states that human development is influenced by the different types of environmental systems. The Ecological System Theory states that we encounter five different environments throughout our lifespan that may influence our behavior. This system includes The Micro System, The Mesosystem, The Exosystem, The Macro System, and The Chronosystem.

The Micro System

Refers to groups that most immediately and directly impact the child's development including family, school, religious institutions, neighborhood, and peers.

The Mesosystem

Interactions between the family and teachers. Also, relationship between the child’s peers and the family

The Exosystem

Involves links between a social setting in which the individual does not have an active role and the individual's immediate context

The Macrosystem

Describes the culture in which individuals live. Cultural contexts include developing and industrialized countries, socioeconomic status, poverty, and ethnicity. A child, his or her parent, his or her school, and his or her parent's workplace are all part of a large cultural context

The Chronosystem

Made up of the environmental events and transitions that occur throughout a child's life, including any sociohistorical events
