- Abstract
The present study combined a novel hypothetical investment game with functional magnetic resonance imaging to examine how moral conflict biases our real decision preference when it is not obvious or explicitly presented. Investment projects were chosen based on their prior subjective morality ratings to fit into 2 categories: a high level of moral conflict (HMC) or a low level of moral conflict (LMC). Participants were instructed to invest high or low amounts of capital into different projects. Behavioral and neural responses during decision making were recorded and compared. Behaviorally, we observed a significant decision bias such that investments were lower for HMC projects than for LMC projects. At the neural level, we found that moral conflict-related activity in the anterior cingulate cortex (ACC) was higher in the HMC condition than in the LMC condition and that reward-related activity in bilateral striatum was lower. Dynamic causal modeling further suggested that the moral conflict detected in the ACC influenced final decisions by modulating the representation of subjective value through the ACC's connection to the reward system.
