Understanding the relation betweenmotivation and pilot impulsive decision-making is extremely important in the context of aviation human factors.One way to operationalize motivation is by presentingparticipantswith different reinforces, either primary (e.g. food rewards) or secondary (e.g. financial incentives,arguably playinga crucial role in in-flight decision-making).To establish the role that different reward systems play in decision-making, we tested the extent to which distinct brain regions aresensitive to the reinforcement content. Combininganeuro-economics approach with a voxel-based lesion method, we foundthat distinct regions within orbito-frontal cortex (OFC) are differentially involved in impulsivitydecisionsbased on the reinforcement type. In contrast, lesions in dorsolateral prefrontalcortex (DLPFC) were not associated with such decisions. Theseresults suggest a distinction between reward typesatthe neural level,andthus emphasize the importance of investigating how different reinforces can affectflight activityespecially in pilot impulsive, risk-taking behavior.
