The Impact Of Interpersonal Emotions On Risk Decision-making And The Time Course

Identifying and processing emotional information successfully are the important skills of social communication.We face many kinds of emotions in interpersonal interactions.the extant researches have systematically investigated how the emotion of the decision maker influence his own decision making,living the influence of others’emotional expression upon one’s decision making not fully studied..In this case,the paper adapted the Gehring decision-making tasks into interactive games.The game requires the subject and lab assistant to go through gambling games.It presents each opponent’s expressions as emotion feedback in terms of supralimindal and subliminal methods,and collects tested behaviors and EEG data as dependent variables to investigate how interpersonal emotional expression affect individual decision making as well as its time process.Experiment One:adopt the suprathreshold to present the opponent’s emotion,and the subject design goes as 2(emotion:anger,happiness)times 2(results valence:losing money,winning money).The experiment situation is an interactive Gehring decision-making task,which requires the subject to choose from two different stakes-10 and 50.Before the experiment,the subject is told that he will complete the game together with the assistant,and they are in a competing relation in which one wins money while the other loses.In each round,computer programs determine who is the gamer and who is the beholder.The gamers should complete the game,and the beholder should observe the emotions of gamers and how they react to winning or losing money.Both the emotion and reaction shall be presented together.The behavioral results shows that the subject tends to take a risk seeking next time when he loses money;the subject takes longer time to react when he loses money and the opponent is in a good mood.Neurophysiological results show that if the opponent is happy,the subject’s losing money induces bigger FRN than his winning money,and the subject’s winning money induces bigger P300;if the opponent is in anger,the subject’s losing money induces smaller FRN,and there’s little difference about P300.Experiment Two:adopt the subliminal to present the opponent’s emotion,and the subject design goes as 2(emotion:anger,happiness)times 2(results valence:losing money,winning money).The situation is similar as Experiment One,but the subject is not informed that there’s the emotion feedback.After completing the game,the subject shows opponent’s expression 16ms.The behavioral results shows that the subject takes longer time to react when he wins money and the opponent is in happiness.Neurophysiological results show that the angry emotion of the opponent induces bigger FRN than his happiness emotion;The subject’s wining money induces bigger P300 than his losing money.This paper suggests that:interpersonal emotions affect individual decision-making,and the influence model of the suprathreshold and subliminal varies;the different phrases of reviewing interpersonal emotions include rough processing of FRN and deep processing of P300;all results support EASI,which means that the happy emotion leads an individual to adopt more reasoning which is based upon emotion information,and the angry emotion leads an individual to adopt more Affective processing...
