The current experiment investigated whether attentional orienting would be influenced by the congruence between participants’ moral preferences and the moral associations of cues, and whether this relationship was modulated by cardiac vagal tone, measured by heart rate variability (HRV). Following HRV measurement, participants viewed neutral male faces who made either deontological or utilitarian moral judgments in sacrificial moral dilemmas. These faces served as cues in the subsequent spatial cueing task, during which participants had to detect targets following these face cues. The results showed that higher utilitarian moral judgment scores were associated with faster attentional disengagements from both deontological- and utilitarian-associated face cues, but only among participants with lower resting HRV. These findings offer initial evidence of morally modulated attentional orienting, which depends on individual differences in cardiac vagal tone.
