The Experimental Reseach On The Impact Of Emotional Arousal Andvalence On Decision-making

In recent years, the researchers pay attention to the effect of the emotion on the human realization process. Many people give attention to the effect of the emotion on decision-making. At the same time more and more theory on emotion and decision-making was produced. Delay discounting task and probability discounting task are important tasks in decision-making research. This paper studied the effects of emotion on the two decision-making task from emotional arousal and valence by emotional pictures chosen from IAPS.The research consisted of two experiments. About 80 undergraduates come from An Hui normal university took part in the experiment. And both of the experiment procedures were displayed on the computer in a standardized form. Before the students made decision, we induce their emotion through emotional pictures, and then asked the students to complete the task of decision. In the first experiment the decision task is delay discounting task (DDT)and in the second experiment is probability discounting task(PDT).The results reveal that:(1)Emotional arousal can apparently influence decision-making. The delay discounting and probability discounting rates of students'who were induced high-arousal emotion are both significantly higher than students'who were induced low-arousal emotion. High-arousal emotion can influence decision-making because it employ more attentive capacity.(2)Emotional valence have no apparent influence on decision-making. The delay discounting and probability discounting rates of students'who were induced positive valence emotion have no significant differences with students'who were induced negative valence emotion. The influence of valence have been submerged by emotional arousal.(3) In delay discounting task, there is no significant interaction between emotional arousal and valence. In probability discounting task, there is significant interaction between emotional arousal and valence. The probability discounting rates of students'who induced high arousal and negative valence emotion are the highest. The research indicate that hign-arousal emotion employ more attentive capacity, thereby increasing impulsivity and decreasing risk-taking. So, Impulsivity and risk-taking are two different characteristics.
