Research On Individual Emergency Decision Preferences Under Unconventional Emergencies Based On ERP Technology

With the rapid development of society,human footsteps throughout every corner of the world,which caused the destruction of the ecological environment becoming increasingly serious,and national and ethnic conflicts continuing to occur.As a result,the frequency of occurrence of a variety of unconventional emergencies increased gradually.Most of the unconventional emergencies come out after a long period of time,so it will bring serious harm to society and economy and cause widespread influence.Therefore,it is urgent to set up a perfect emergency management system.This paper focuses on the individual decision-making preference under negative emotional state and emergency emotional state aroused by unconventional emergencies,and based on ERP experiment studies on the difference of the brain's automatic processing ability under two different emotion inducing conditions,and gives the explanation from the perspective of cognitive neuroscience.We hope to contribute to the construction of the theory system of unconventional emergency management,and give some scientific suggestions on how to deal with unconventional emergencies.First of all,this paper put forward the research questions on the basis of a large number of previous studies,and expounded the research background and significance,and summarized the research status of related issues.Then,the paper briefly introduced the related theories of unconventional emergencies,emotional impacts on decision-making,and event-related potentials to provide theoretical support for the following research questions.Secondly,based on the relevant theories and research status,this paper designed a behavior experiment to study the problem of individual decision-making preference under the state of negative emotion and emergency emotion,and used SPSS17.0 software to analyze the data.The study found that,under the background of unconventional emergencies,decision maker's preference was influenced by the cross effect of the current mood and decision-making background frame,which arose the phenomenon of preference reversal.The result provided a way for the following study on ERP.Again,designed the ERP experiment by introducing event-related potentials and selected the auditory MMN as the represent waveform of brain information automatic processing ability to study the brain information automatic processing ability under negative emotional state and emotional state of unconventional emergency.Finally,the experimental results of this study were discussed,and based on the experimental results,some scientific suggestions were given to deal with unconventional emergencies.
