Outline of Final Research Achievements

We clarified various aspects of many-layered logical judgement-decision making processes, by introducing new methodologies combinig theoretical methods and experimental methods. Our findings include; (1) effects of different ways of graphic-diagrammatic information-representation on judger's logical inferences and multi-attribute decision making; (2) influences of genetic factors on individual's decision making, logical inference and cognitive abilities; (3) influences and potential influences of the logical-philosophicalnt works of the early 20th century (Husserl, Hilbert, Wittgenstein)on our contemporary logical theories.(4) We developed linear logical vews and possible　world-semantical views of classical-logical judgments and gave their applications to computer scientific judgments (e.g., on logical judgment for communication network security). (5) We also gave a new relationship between game theory and epistemic logic, and between philosophy of action and dynamic logic.
