The Relationship Between Behavior Decision Information And Emotion

Individuals always have to make decisions under uncertain conditions, however, the profit and loss information in decision--making is able to activate the corresponding emotional experience. Exploring the role of emotion in decision--making has always been a hot research topic. Therefore, this research, based on the paradigm of implicit association test, conducted a research on the profit and loss information in decision--making and the internal neural system that activates emotional compatibility.This research includes two ERPs experiments and the results are listed below:(1) In the experiment of ERPs based on the I AT paradigm of profit information processing, the behavior statistics shows, the reaction time of profit stimulate differs notably under the compatibility task and incompatibility task, compared with the compatibility task condition, the reaction time of profit stimulate is longer under the incompatibility task than that in the compatibility task condition; the incorrectness of profit stimulate has great differences under the incompatibility task condition and compatibility task condition, compared with the compatibility task condition, the incorrectness of profit stimulate is comparatively higher under the incompatibility task condition. The statistics of ERPs shows that there is no notable difference of the frontal lobe N2 latency and amplitude under the incompatibility task condition and compatibility task condition. The frontal lobe of P3 amplitude of profit stimulate has a notable major effect under the incompatibility task and compatibility task, under the compatibility task condition, the profit stimulate induces a higher P3; the P3 latency of profit stimulate has a notable major effect under the incompatibility task and compatibility task, the frontal lobe P3 latency of profit stimulate is longer under the incompatibility task condition.(2) In the experiment of ERPs based on the I AT paradigm of loss information processing, the behavior statistics shows, that he loss stimulate has no significant differences in reaction time and incorrectness in different experiments; The statistics of ERPs shows that the frontal lobe of N2 and P3 latency and amplitude that are activated by loss stimulate have no notable significance.Based on above results, conclusions are drawn as follows:First, in decision--making of profit information processing, the amplitude and latency are reflection of an biological index concerning the individual evaluation profit and its activated emotional compatibility. Under the incompatibility task condition, the frontal and central areas that are activated by profit stimulate has a longer P3 latency and a decreasing amplitude.Second, in decision--making of loss information, the loss information and its activated emotions have not induced ERPs elements in frontal and central characteristic areas.Third, the experiment of ERPs based on paradigm of implicit association test can provide object evidence in neurosciences with evaluation profit information and its activated emotional compatibility. However, there will be improvement for evaluation loss information and its activated emotional compatibility.
