Can Empathy Restrain Deception? Evidence Of ERPs

Deceptive behavior refers to the behavior intended to cultivate the false belief of others in order to make them wrong or wrong.Compared with honest behavior,deceptive behavior involves several psychological processes: concealing information stored in the brain,constructing relevant information about cheating response,and carrying out deceptive behavior.It is found that some personality traits are related to deceptive behavior.In this paper,combining the kindness personality traits in Chinese cultural background and using event-related potential technology,the deceptive behavior of high-kindness and high-weight feelings and low-kindness and low-weight feelings people in different situations is examined.Understand whether personality traits affect individual behavior and development.In experiment 1,we used double selection Oddball paradigm and event-related potential technology to investigate whether the subjects in the high group had more emotion.In experiment 2,the characteristics of deceptive response and the influence of different types of emotional feedback on deception behavior were investigated by using the cut-target-feedback paradigm and event-related potential technique.In experiment 3,the characteristics of deceptive response of two groups of subjects under real money stimulation were studied by using double selection Oddball paradigm and event-related potential technique.The results show that:In experiment 1,there was no significant difference in the judgment reaction time and the number of keys between the two groups.The images of strong emotional intensity induced more obvious P2 ? P 3 component in the high group,and the average amplitude was larger and the incubation period was longer,while in the low group,the N1 component was more obvious,and the average amplitude was larger and the latency was longer.In experiment 2,the response time of deceptive reaction was longer than that of honest reaction,whether in high or low groups.The response time of fear and happy faces was shorter than that of neutral faces.Deceptive preparation induced greater average amplitude and shorter latency of N2 component in low group,and P300 effect was induced by feedback in feedback stage.In experiment 3,when the value orientation of income was self-20,the reactiontime of the two groups was longer.When income distribution type is 20%,target stimulus and non-target stimulus can induce more obvious P2?N2 component,and when income distribution type is 80% self,it induces more obvious P3 component in low group.The conclusion of this study is as follows:(1)The emotional information of pictures is preferentially processed.In the judgment of emotional picture,the subjects of high group tend to invest more emotion,and the high group are more rich in emotion.(2)The deceptive preparation activities of the low group were more obvious,the response time of the low group was shorter,and the low group paid more attention to the feedback information of the results.(3)In the context of money stimulation,the low group participants had more deceptive behaviors.
