* When and under what influences did scientific psychology originate in different parts of the world?
* What are the intra- and international/regional sources of influence that have affected its development into the present form?
These questions were applied to three regions and three countries, which were as follows (the names of the authors in charge are in parentheses):
Latin American countries (Juan Jose Sanchez-Soza, Mexico), Scandinavian countries (Ingvar Lundberg, Sweden), German-speaking countries (Lothar Sprung, Germany), Spain (Helio Carpintero, Spain), China (Qicheng Jing and Fu Xiaolan, China), and Japan (Tadasu Oyama, Japan).
Visual presentations, including maps of these regions/countries, tables showing the pedigrees of scientific psychology, and chronological tables with names of psychologists and affiliations, illustrate the stream of influences both temporally and spatially. These figures and tables are also used to look forward to the psychology of the 21st century.
This special issue is based on the symposium held at XXVII International Congress of Psychology in Stockholm in 2000.
