Research On Emergency Decision - Making Preference And Brain Automatic Information Processing Induced By Emergency Situation

The role of the emotions to the emergency decision-making start attracting the attention of scholars in recent years. Compared with the ordinary decision-making, emergency decision-making is often in all kinds of disaster emergency situations, due to the high risk inherent in emergency situations, sudden, the fuzzy characteristics of information, these characteristics can cause negative emotional state. Whether emergency emotional state is the same as the positive and negative emotional state can influence people’s decision preference? How emotions affect the brain mechanism of emergency decision? The research has not been effective.Based on this research this thesis designed two experiments. Experiment 1 based on the paradigm of past emotions affect emergency decision-making, using true case to study the neutral, positive, negative and crisis situation induced by the emotional affect emergency decision-making preferences. Research results show that, first of all, emergency situations can effectively induce the negative emotional experience of subjects, the score, the subjects under crisis PANAS scale of NA (negative emotions scale) is significantly induce high before, and compared with negative emotions evoked subjects under emergency decision-making preferences become more risky, and positive emotions induced with neutral emotions evoked the subjects under the conservative decision, the results support the "emotion maintain" theory. Experiment 2 use ERP technology research different titer of emotions as well as emergency situations of information processing affect automatic brain information processing. The research results show that, compared with the other different emotional stimuli, in emergency situations, emotional information processing and induced by stimulation of different color visual MMN.According to the results in this paper, the following conclusions:1, different titer of emotional experience has different influence on emergency decision-making, under neutral emotion and positive emotional states of emergency decision-making partial conservative, and the participants in the event of negative emotional state emergency decision-making. Results show the theory of "emotion maintain".2, emergency situation can effectively induce the negative emotional experience of participants, and try to make more risky decisions than negative emotional state.3, with different titer of emotional information processing and automatic brain information processing ability was not significantly change.4, in emergency situations, and by the border of emotional information processing induced by stimulation of different color visual MMN average area significantly decreases, and the midbrain automatic information processing in the emergency situation has been damaged.5, the complexity of the emergency situation affects brain ability of automatic information processing, thus induce the mood of the emergency situation may indirectly affect people’s emergency decision-making process; And ordinary mood does not damage induced brain automatic processing ability, emotional impact on decision-making mechanism may not be due to the affected brain automatic processing of information.
