This project seeks to disentangle whether entrepreneurs perceive or cognitively process risk and uncertainty differently than comparable others. We use behavioural experiments tapping into decision making under risk and ambiguity as well as reward processing while tracking changes in neural activation in sections of the brain which have been shown to be associated with this type of decision making. Uncovering these differences in the neural processing of risk, ambiguity and reward between entrepreneurs and non-entrepreneurs, could explain the behavioural differences that has been observed in entrepreneurs with regard to decision making in risky and ambiguous settings. We plan to include 70 participants consisting of 3 groups of equal sizes: serial entrepreneurs, one-time entrepreneurs and a control group.
