ABSTRACT
Environmental psychology is interdisciplinary in nature, therefore perhaps even more than some other fields of applied psychology it relies on a diverse range of theory. In any area of applied psychology there is no single or unified theory. Rather, applied psychologists have access to the total range of theoretical perspectives in psychology. Indeed this is as it should be because it allows greater scope and flexibility in application and there is little reason to expect that the complex subject matter of psychology, human experience and behaviour, should lend itself to a simple or single theoretical explanation.
