Environmental psychology examines the interrelationship between environments and human behavior. It includes, but is much broader than, the study of coupled human-environment systems (i.e., coupled human and natural systems, CHANS). The term environment is broadly defined to include natural, built, social and informational settings. When solving problems involving human-environment interactions we believe that it is essential to have a model of human nature that understands the conditions under which humans behave in a decent and creative manner. The field develops such a model of human behavior while retaining its broad and inherently multidisciplinary focus. Using this model it explores such dissimilar issues as common property resource management, wayfinding in complex settings, the sources of well-being, the effect of environmental distraction on human performance, the characteristics of restorative environments, human information processing, and the promotion of environmental stewardship behavior. Environmental psychology recognizes the need to be problem-oriented, using, as needed, the theories and methods of related fields (e.g., psychology, sociology, anthropology, integrative medicine, economics, social work, planning, design, landscape architecture).
