We infer the thoughts and feelings of other people by takingtheir perspectives, the accuracy of which depends on abilitiesto control egocentric bias. Similar processes could arguablybe used to understand how we would be affected by futureevents, such as delayed rewards in intertemporal decisions, byallowing us to accurately take the perspective of future selves.In this paper, we test this idea in two studies. In Study 1, weattempted to lower preferences for delayed rewards toexamine if this redced abilities to control egocentric bias in avisual perspective-taking task. In Study 2, we examined theneural overlap in intertemporal decision-making and thecontrol of egocentric bias in a false-belief theory-of-mindtask. In both studies, a positive relationship was identifiedbetween behavioural and neural markers of egocentric biascontrol and preferences for delayed rewards. The overallpattern of results suggest the overlap in processes ofegocentric bias control and those that determine preferencesin intertemporal choices, and demonstrate for the first timethe effect of sexual arousal on social cognition in reducingabilities to separate one’s own perspective from others’.
