| Outline of Final Research Achievements |
Humans can imagine possible future events. They can also recognize that their life is not endless. In this project, I examined how thinking about own death affects future-oriented monetary decisions by using functional magnetic resonance imaging (fMRI). During intertemporal choice, participants devalued a future reward to account for its delayed arrival when they engaged in thinking about death. This tendency was stronger in participants who tended to associate a death-related event with monetary decisions. These participants also exhibited enhanced activities in the amygdala and dorsal anterior cingulate cortex during the choice of larger delayed rewards when they imagined death. These results suggest that thinking about death makes people less willing to wait for future reward, possibly due to the emotional conflict that arises between the selecting the future reward and the awareness of the inevitability of death.
