| Outline of Final Research Achievements |
In order to reveal the neural basis of motivational modulation, we measured the brain activity of participants who were performing modified versions of stopwatch task using functional magnetic resonance imaging. The participants preferred the condition where they could choose the stopwatch to play by themselves. In the self-determined choice condition, success rate increased and the drop in the ventromedial prefrontal activity disappeared. These findings suggest that a mechanism that regards a failure as a step for future success exists in the ventromedial prefrontal cortex and this mechanism is recruited in the self-determined choice condition for increase in motivation as well as performance. The striatum was more activated by the success for point increments than by the success for avoiding point decrements. These findings suggest that the reward system in the brain is activated for motivational increase more efficiently in the approaching frame than in the avoidance frame.
