Impulsivity and risky decision making among taxi drivers in Hong Kong: An event-related potential study.

•We use an event-related potentials experiment to examine the neural processes involved in risky decision-making by taxi drivers.•Offenders were less sensitive to the consequences and more attuned to the magnitude of reward than nonoffenders.•Offenders were willing to make more risky decisions.•The offenders in this sample were more impulsive than their nonoffending counterparts.
