Historically, Environmental Psychology and the related studies of the interplay between people and their physical surroundings has had its origins in the developed countries of the North Atlantic basin. Other developments in Australia and South-East Asia have also focussed on problems that clearly have their roots in the problems associated with affluent societies. Concerns such as effective office building design, the maintenance of wilderness and associated resource planning concerns, together with problems of forming internal representation of well-established urban environments, are all issues that assume a well-founded industrial base and a firmly established democratic political system. It is therefore not surprising that the methodologies that are characteristic of much research on people and their relationships with their physical surroundings are appropriate to developed countries. Theoretical frameworks will be formed such as those, for example, that derive from the relationships between established nuclear families in a developed country. The study of privacy is a very good case in point. The purpose of this symposium is to explore what methodology and theories can be transported to developing countries and what topics of study have a special relevance to the problems that the third world is facing.
