Physical environment constitutes everything surrounding man: the built environment and the natural environment. Human behavior is influenced by its physical environment, yet the relationship between the two has received little concern. Behavioral and other psychologists have talked about the role of the environment in shaping behavior. Architects and urban planners need to be conscientious of the built environment they are designing if they are to contribute to the well-being of residents in public housing or multi-family dwellings, the well-being of users and staff personnel in offices, patients in mental institutions, or inmates in penal institutions.
