Fuzzy theory provides a computational framework for dealing with fuzziness of human cognition and behavior. Most of psychological researches have been focused on fuzzy set theory, and only a few researches have used fuzzy reasoning for psychological study. However, since fuzzy reasoning represents human decision making processes by fuzzy production rules, fuzzy reasoning must be very useful to model human decision making processes. The present paper exemplifies the applications of fuzzy reasoning to psychological study, and discusses the implication and the applicability of fuzzy reasoning for modeling human decision making processes and supporting human decision making.
