| Abstract: | To investigate how individual differences in moral judgmentcompetence are reflected in the human brain, we used event-relatedfunctional magnetic resonance imaging, while 23 participantsmade either socio-normative or grammatical judgments. Participantswith lower moral judgment competence recruited the left ventromedialprefrontal cortex and the left posterior superior temporal sulcusmore than participants with greater competence in this domainwhen identifying social norm violations. Moreover, moral judgmentcompetence scores were inversely correlated with activity inthe right dorsolateral prefrontal cortex (DLPFC) during socio-normativerelative to grammatical judgments. Greater activity in rightDLPFC in participants with lower moral judgment competence indicatesincreased recruitment of rule-based knowledge and its controlledapplication during socio-normative judgments. These data supportcurrent models of the neurocognition of morality according towhich both emotional and cognitive components play an importantrole. |
