Abstract: Aversive emotions are likely to be a key source of irrational human decision-making but still little is known about the neural circuitry underlying emotion-cognition interactions during social behavior. Here, we show that incidental aversive emotions distort trust decisions and cause significant changes in the associated neural circuitry. Experimentally-induced negative affect reduced trust, suppressed trust-specific activity in left temporoparietal junction (TPJ), and reduced functional connectivity between TPJ and emotion-related regions such as the amygdala. The posterior superior temporal sulcus (pSTS) seems to play a key role in mediating the impact of emotion on behavior: Functional connectivity of this brain area with left TPJ was associated with trust in the absence of negative emotions, but aversive emotions disrupted this association between TPJ-pSTS connectivity and behavioral trust. Our findings may be useful for a better understanding of the neural circuitry of affective distortions and may help identify the neural bases of psychiatric diseases that are associated with emotion-related psychological and behavioral dysfunctions.
