Study On The Influence Of Accidental Negative Emotion On Ambiguous Decision-making

In the study of early decision making,researchers often assume that decision-makers are "rational people",the decision is pure cognitive processing,and ignore the influence of emotion on decision making,and the emotion is brought into the study of decision with disappointment theory and regret theory.loomes,& Sugden,1986).In addition to the expected mood(anticipated emotions),which is represented by regrets and disappointments,current research studies the emotions that policymakers experience in decision-making,which is called immediate emotion.Instant emotions include advances in mood(anticipatory emotions)and occasional emotions(accidental emotions).There have been many studies on the expected mood,among which Damasio's research on the expected mood has been widely concerned.On the basis of predecessors ' research,this paper introduces the study of accidental emotion into the anticipation emotion,compares it with Damasio's theory,and explores the influence of accidental emotion and expected emotion on ambiguity decision.Research purposes: In the previous study,this study attempts to explore whether in the negative accidental emotional conditions,the subjects in the ambiguity decision-making will be more cautious,so as to improve the performance of ambiguity decision-making.Research methods: The study included a total of two experiments: The experiment was designed using a single factor(negative emotional stimulation vs.neutral emotional stimulation)to perform a ambiguity version of the Ballon Analogue Risk Task(BART)in the context of negative occasional emotional stimulation and neutral occasional emotional stimulation.Experiment two is to use single factor(negative emotion stimulation vs neutral emotion stimulation)experimental design,with the improvement of experiment one,the subjects were asked to carry out the Iowa Game Task(IGT)under the action of continuous negative accidental emotion stimulation and continuous neutral accidental emotion stimulation.Combining the results of two experiments,we found that although the influence of accidental negative emotion may impair the performance score of an adapted version of BART in the same ambiguity decision making,the effect of an occasional negative emotion on the subjects in IGT increases the scores of the subjects in the task.In other words,although it is the influence of accidental negative emotion on fuzzy decision,the subjects have different responses under different ambiguity decision conditions.Conclusion: Although in the same vague state,but in the occasional negative emotional impact,the test in IGT will improve the results,BART's results will be reduced.
