The present project was planned to describe the perceptual phenomena in various modalities and to examine experimentally the underlying principles from view point of the experimental phenomenology and Gestalt psychology, and then to propose a general and exclusive theory of perceptual organization. And also the modern theoretical and methodological significance of descriptive and phenomenological approaches in study of perception was examined. Our argument derived from various experimental results was presented and discussed actively in international symposium and round table conferences in scientific societies. These two problems, theoretical or methodological examination and experimental evidence, have been treated equally in our project.
Through the results of experiments in different phenomena such as visual motion, phenomenal transparency, visual stratification, perceptual contrast, auditory stream segregation, and event perceptions including perception of "wind", the traditional theories, especially the validity and the limits of application of Gestalt principles in perceptual organization, were examined minutely and then partially revised along new findings in several phenomena including some auditory experiences. These studies have been published in the technical journals and presented in scientific societies.
Even through the phenomena taken up in the present project are not necessary new ones, further reexamination is required as shown by G. Kanizsa's demonstrations (1980). Nowadays, while the importance of descriptive analysis is generally recognized, most of researchers seem to be interested in physiological models or computational models. Therefore, it should be taken heed that these approaches to perceptual research run a risk getting into the classical scientism or the reductionism. In conclusion we stressed that the study of perception in psychology must be more descriptive and experiential but not physiological or physical.
