APPLICATION OF SIGNAL DETECTION THEORY TO ANALYZE GENDER CHARACTERISTICS AND TRAINING EFFECT IN SITUATION AWARENESS USING VISUAL INTERFACE

Abstract
Abstract - This study analyzed the gender characteristics and training effects in situation awareness through visual interface using signal detection theory. Situation awareness is an important factor in system safety in complex human-machine systems, such as nuclear power plants. For correct situation awareness, it is important to appropriately detect the information necessary for situation awareness. In this study, an emergency operation simulator for a nuclear power plant was created, and an experiment was conducted to detect the changes of indicatorsinsituation awareness. For the experiment, a simulator showing four representative accident situations of nuclear power plants–LOCA, SGTR, SLB, and LOV–was created. The subjects conducted an experiment to detect changes in six indicators that needed to be checked to determine each accident situation on the simulator screen. Twenty university students (10 males and 10 females) participated in the experiment. To determine the training effect, an experiment was conducted by dividing the subjects into the trained and the non-trained groups. The experimental results confirmed that the gender difference in the sensitivity of signal detection and response bias in situation awareness was not statistically significant. It was confirmed that the training effect was significant for both sensitivity and response bias. These results indicate that it is not necessary to distinguish gender in tasks that require situation awareness. Because the trainingsignificantly affects the signal detection ability for situation awareness, it can be seen that it must be performed indispensably.
