Reward and self-consistency: Dissecting the role of social brain and cognitive control in moral decisions

---

Highlights

• The behavioral results can be best fitted by a multi-attribute time-dependent drift diffusion model (tDDM), in which self-interest and self-consistency had different onset timings and drift rates.
• Univariate analysis on the fMRI data showed significant activations in regions related to cognitive control and reward in the dishonesty condition.
• The drift rates of reward and the related brain regions were correlated to the respective ROIs, which was further confirmed through fMRI functional connectivity analysis.
