Temporal correlates of intuition and cognitive control in moral decision, making in different social contexts

Abstract

In the stream of flurry of publications grappling different paradigms to tackle underlying mechanisms of moral decision-making, EVENT RELATED POTENtial (ERP) studies is beginning to explore psychophysiological components in the moral domain, focused on observing various moral behaviors in the experimental situations. This research was aimed at providing a new method of study investigating neural correlates of subjective moral decision-making in which we hypothesize that the social congruent or in-congruent context, could emerge a salience brain response in intuitive or cognitive control related responses toward moral dilemmas. Electrophysiological data were recorded from the scalp a 32-channel recording system complying with the international 10–20 system. The average N2 (175–300 ms) and LPP (300–600 ms) amplitude and latency were measured after the onset of putative counterpart response. Repeated measure ANOVA revealed that there was a difference between congruent versus in-congruent social response to high conflict scenarios in LPP amplitude in right lateral and frontal electrodes F_{(4, 174)} = 5.812, P < 0.001 (Fig. 1). The findings also, suggest that N2 latency in less conflict moral scenarios may appear earlier compared with high conflict moral scenarios during in congruent social response in frontal electrodes especially left area F_{(3, 174)} = 3.013, P < 0.05 (Fig. 2, figures are not available for this abstract). In conclusion, these results were either extend previous neurophysiological findings on classic moral scenarios and consistent with the notion that right hemisphere would be much more representative of cognitive control process during high conflict moral decision-making, while left frontal electrodes engaged in early intuitive process.
