报告简介：

People hate being deceived, yet we are always lied to by strangers and even love ones. In our studies, we investigated the neural response to lies with beneficial/harmful outcomes and lies come from in-group/out-group members. In the fMRI study, we used a modified, cheap talk sender–receiver game in which participants were the direct recipients of lies and truthful statements resulting in either beneficial or harmful monetary outcomes. Both truth-telling (vs. lying) as well as beneficial (vs. harmful) outcomes elicited higher activity in the nucleus accumbens. Lying (vs. truth-telling) elicited higher activity in the supplementary motor area, right inferior frontal gyrus, superior temporal sulcus and left anterior insula. Moreover, the significant interaction effect was found in the left amygdala, which showed that the monetary outcomes modulated the neural activity in the left amygdala only when truth-telling rather than lying. In the EEG study, we recruited participants to play a modified estimator and advisor game to investigate the mental and neural processes to lies and truth conveyed by in-group and out-group members. No significant N1 and P3 amplitude differences between in-group lies and truth were found, while outgroup lies elicited larger P3 amplitude than outgroup truth and out-group truth elicited larger N1 amplitude than outgroup lies.
