Experimental study on the operators' cognitive activities had been performed using nuclear power plant simulator. The specific feature of the present study is that the state of the operator during the interaction through the man-machine interface is analyzed based on the diverse information; 1) Estimated cognitive state,2)Estimated mental work load,3) Operational sequence history, 4)Questionnaire and 5)Video record. These informations are integrated and graphically represented on the form of Chronological Diagram, by which the operators' dynamic cognitive behavior can be analyzed. Results of the simulator experiments, in which three expert operator participated, demonstrated that the present method can provide the valuable information concerning the operators' cognitive behavior during the task of anomaly diagnosis.
