This is the first in a series of volumes concerned with research encompassed by the rather broad term "environment and behavior. " The goal of the series is to begin the process of integration of knowledge on environmental and behavioral topics so that researchers and professionals can have material from diverse sources accessible in a single publication. The field of environment and behavior is broad and interdiscipli­ nary, with researchers drawn from a variety of traditional disciplines such as psychology, sociology, anthropology, geography, and other social and behavioral sciences, and from the biological and life sciences of medicine, psychiatry, biology, and ethology. The interdis­ ciplinary quality of the field is also reflected in the extensive involve­ ment of environmental professionals from architecture, urban plan­ ning, landscape architecture, interior design, and other fields such as recreation and natural resources, to name just a few. At present, the field has a somewhat chaotic flavor, with research being carried out by a variety of scholars who publish in a multitude of outlets. Many researchers and practitioners are unaware of the state of knowledge regarding a specific topic because of the unavailability of integrated reference materials. There are only a handful of books dealing with environment and behavior, most of them unintegrated collections of readings, with only an occasional systematic analysis of some facet of the field.
