Generous behaviour is known to increase happiness, which could thereby motivate
generosity. In this study, we use functional magnetic resonance imaging and a
public pledge for future generosity to investigate the brain mechanisms that link
generous behaviour with increases in happiness. Participants promised to spend
money over the next 4 weeks either on others (experimental group) or on
themselves (control group). Here, we report that, compared to controls,
participants in the experimental group make more generous choices in an
independent decision-making task and show stronger increases in self-reported
happiness. Generous decisions engage the temporo-parietal junction (TPJ) in the
experimental more than in the control group and differentially modulate the
connectivity between TPJ and ventral striatum. Importantly, striatal activity
during generous decisions is directly related to changes in happiness. These
results demonstrate that top-down control of striatal activity plays a
fundamental role in linking commitment-induced generosity with happiness.
