Bronfenbrenner has different approach towards environment. He has explained the environment in terms of five systems organized in a hierarchical form which is structured like a bird's nest which can be seen as below.
Bronfenbrenner's explanation about the five systems of environment is as under : Micro System : It is composed of the system in which the individual lives. This structure includes units like the person's family,peers,school and neighbourhood. In this system majority of the interactions are with parents, peers and friends.
Meso System : It is such a system in which various Microsystems are related. e.g., family experiences of the child have effect on his interactions with friends and teachers. The children from broken families experience difficulty in their adjustment with friends.
Exo System : This system indicates the effects of the experiences of situations that are not in close contacts of a person on the people who are in close contact with that person e.g., person's experiences in work place influences his interaction with his wife and children. The conflict with the boss in the office finds expression in the form of anger on the wife and children at home.
Macro System : This system is associated with the culture in which we live. Culture includes beliefs, values, customs etc. which are followed and practiced by majority of the people.
(e) Chrono System : It refers to patterns of behaviour which are related responses to the change which have occurred in life course in socio historical context. e.g., in a person who is very much optimistic and industrious in young age, with the growing age there is a decline in his activities and ambition.
