The Effect Of Emotion Factors On Subjective Probability Judgment

Subjective probability judgment is a cognitive processing contacted with decision-making. Some research had investigated how emotion impacted the decision-making, but few people researched about the effect of emotion on subjective probability judgment.In the present study, there are two experiments for it. Experiment 1 studied the value of subjective probability judgment with the different event-valence, object-reference, description of event and different time-pressure. The results showed people gave more the value of subjective probability judgment to positive events than negative events. The different reference and the event-valence affect on it. And the description of event and the feeling of tension impacted together. In experiment 2, event-related brain potentials were recorded when people made subjective probability judgment for the different valence events and reference in different mood states. The data suggested there was a significant interact effect between emotion and reference during 40-100ms and other-reference elicited more negative deflections than self-reference. When it was 200-250ms, positive mood elicited more positive deflections than negative mood, but negative events elicited more positive deflections than positive events.This suggested that emotion certainly would affect subjective probability judgment from early processing stage and through the processing.
