The Influence Of Facial Emotion And Trust Behavior On Trust Decision-Making

In order to explore the effects of interactive facial emotions and trust behavior on trust decision making.In the present study,a total of 293 participants were selected.,using a repeated interactive version of the trust game paradigm to explore the impact of facial emotions of happiness,anger,sadness and disgust,as well as the arousal of facial emotions and the trustworthy/untrustworthy behavior of the others on individual trust decisions through three experiments.Experiment 1 verifies the impact of happy and angry facial emotions and trust behavior on individual trust decision making.Experiment 2,based on Experiment 1,adds the arousal variable,and explores the impact of high and low arousal happiness and anger facial emotions and trust behavior on individual trust decision-making.Experiment 3 selecting sad and disgust facial emotions,and considers the effect of arousal to explores the impact of high and low arousal sad and disgust facial emotions and trust behavior on individual trust decision-making.The results showed that:(1)When the behavior is consistent with the facial emotion(the first block of the two versions),the happy facial emotion will increase the investment amount of participants,and the facial emotions of anger,sadness and disgusting will reduce the participants ’s investment;(2)High arousal facial emotions will make the investment amount of the participant more extreme,that is,compared to low-arousal facial emotion,high-aroused happy facial emotion players will get more investment amount,while high arousal anger,sad and disgust facial emotion players will receive a smaller amount of investment;(4)In addition,when the player’s behaviors are inconsistent,the participants value the current behavior information more.Through the above three experiments,the following conclusions are drawn:(1)The individual can learn the player’s behavior pattern during the repeated interaction with the four players,and compared to the untrustworthy player,participants invest more to the trustworthy player;(2)Individuals invest more in trustworthy players with happy facial emotions than players with only trustworthy behavior,and invest less in untrustworthy players with angry,sad and disgust facial emotions than those who only have untrustworthy behavior;(3)When the player’s facial emotion and behavior are inconsistent,the individual will judge according to the player’s behavior information,rather than the facial emotion information;(4)When the player’s behavior changes,the amount of the investment of the participant will change as the player’s behavior changes,that is,the player’s current behavior will affect the judgment and decision-making behavior of the participant;(5)In addition to disgust facial emotions,happy,angry and sad facial emotions verify that high arousal facial emotions make the investment amount of participants more extreme.In addition,players with high arousal disgust facial emotion receive less than a low level of arousal,but not reaching a significant level.
