Numerous environmental factors have distinct and definitive and effects on childhood development. These factors vary widely, and encompass social, economic and ecological areas, as well as the physical environment in which a child is raised, influenced by neighborhood location, home life and educational facilities. Lorraine Maxwell, associate professor of design and environmental analysis at Cornell University defines these environments as "settings where a person spends a great deal of time and establishes important relationships." (Ulrich 12) When combined, these factors directly and indirectly influence the physical and emotional development of children. Negative impacts of environment on early upbringing have been shown to affect many areas, including behavior and academic performance, social and emotional issues, as well as actual physical development of the brain. Urie Brofenbrenner defined this relationship between development and the environment in his "Proposition 1" which went on to say, "especially in its early phases, and to a great extent throughout the life course, human development takes place through processes of progressively more complex reciprocal interaction between an active, evolving biopsychological human organism and persons, objects, and symbols in its immediate environment." (Brofenbrenner 38). In this early work Brofenbrenner explains the ecological model of human development, and his Proposition 1 explains the importance of the environment in the process of early human development. The Urban Child Institute states “A child’s early home environment has a profound effect on his well-being.” and goes on to demonstrate the link between “negative home environments” (Urban Child Institute 44) during early upbringing with deficiencies in language and behavior, as well as issues with school readiness and cognitive development in a child’s
