When the body knows: Interoceptive accuracy enhances physiological but not explicit differentiation between liars and truth-tellers

Recent research suggests that people experience distinct physiological reactions to lies versus truths. It is unclear, however, if this incorporated into greater truth-lie judgment accuracy. We hypothesized individuals with high interoceptive accuracy—those access bodily experiences and stronger responses emotional stimuli—might be particularly likely accurately discriminate high-stakes, Participants (n = 71) completed two study sessions: the first assessed their accuracy heartbeat detection measures, second deception ability while measuring reactivity. Interoceptive was associated a difference in vasoconstriction liars (vs. truth-tellers), suggesting interoception positively sensitivity deception. accuracy, unrelated While better may enhance signals could from truths, it does not improve explicit
