The roles of reward-processing and cognitive-control in different domains of decision-making

Dr Narun Pornpattananangkul, National University of Singapore

Should one invest in high-risk, high-return stocks or safer bonds? Should one withhold the truth to avoid punishment? Should one forgo a smaller but more immediate reward and wait for a larger one instead? Should one sacrifice his/her money for another stranger? These are some of the common, yet sometimes difficult, decisions we need to make in our everyday life. I will present a series of studies examining the roles of reward-processing and cognitive-control in making these difficult decisions using fMRI, EEG and computational modeling. My talk will focus on four different domains of decisions: risk and uncertainty, moral, temporal and social. I will also discuss implications and future directions of my research, especially on aging and decision-making.
