History of My Research Œ¤‹†‚ÌŒo—ð

I long have been interested in knowing how human beings integrate several pieces of information into one total impression. After I graduated from Waseda University (Doctor course of the Graduate School), I began to study the "impression formation problem" or "information integration theory". These are special research areas of social psychology. In these research areas, several special effects had been found by many investigators' efforts. Through 10 years of research activity, I have found that such effects can be only the illusions caused by some defects of the questionnaire forms employing the traditional rating scale methods. The Rating scale methods are very popular in our daily life. It is always employed in the questionnaire included with products that are purchased. The so-called "5-point scale" or "7-point scale" is a typical rating scale method.

In order to test the hypotheses, I tried applying a variety of models. In all of the models, it seemed to be clear that only the fuzzy-set theoretical models could be acceptable, so I searched and reviewed the psychological papers treating fuzzy-set theory in the experiment.

The review brought rich significant knowledge and the resources to think about the next problems focused after quitting to study the impression formation problems. Especially, I am very impressed that most of the new ideas, occasionally appear in my mind, can be the newest in the world. Usually, it is very annoying and time-wasting tasks for us investigators to check whether our findings are original one or not. But, in about the fuzzy-set theoretical research area, it is almost negligible. Since the Fuzzy-set theory is very young, the possibility of the variations to apply the theory is almost infinitive. After all, I changed the research theme from the traditional "Impression Formation" to the contemporary "Fuzzy-set Theory".

For the first experiment on the fuzzy-set theory, I investigated the correctness of the operation equations used in the fuzzy-set models. Though the equations were proposed in a priori, almost no experimental tests had been done. By conducting the experiments, I confirmed that the fuzzy-set theoretical operation equations could provide a good model of human linguistic behavior. Next, I proposed a new idea to measure the fuzzy membership functions identical to the subjects' linguistic concepts. As a variation of the method to measure the membership functions, I proposed a new idea that was to use the fuzzy-approximation procedure. The new idea was to use the fuzzy-approximate reasoning in predicting the shape of the membership functions.

After the presentation at the workshop of the Japan Society for Fuzzy Theory and Systems, according to the advice of the those who attended, it was reconstructed to a new psychological technique to reveal the subjects' attitudes or opinions more naturally. The new technique was named the "Fuzzy-set Concurrent Rating Method" or FCR-Method by the co-researchers.

The FCR-Method is, in short, a systematic measurement method by separating the traditional bipolar response scale into several (usually two) independent item scales.

For example, the traditional "Good-Bad" scale is, in case, separated into the two scales. One is the monopole "Good" scale, and the other one also the monopole "Bad" scale. The pair of the monopole scales is concurrently used to evaluate the same object. Subjects are instructed to check their responses on each scale independently. The set of responses is summarized to the integrated value and the contradiction-irrelevancy index value.

Recent efforts have been concentrated on developing the measure of the contradictoin or irrelevancy between or among the responses on the concurrently measured independent scales.

Fortunately, the FCR-Method became somewhat popular among researchers who have interests in measuring subjects' attitudes more naturally than using traditional rating scale methods.

Many researchers have helped to develop the FCR-Method. I thank them very much. Especially, Prof. Y. Tsukamoto (Meijo Univ.), Prof. F. Hayashi (Sugiyama Jogakuen Univ.), Prof. T. Kimura (Sugiyama Jogakuen Univ.) and Prof.J.Deng (South East Univ. China).
