The lessons I learned trying to teach my child generosity

Such self-chosen prosocial acts can even be seen in brain scans, according to a study at the University of Oregon; the reward centers of the brain were activated during the act of giving money, but turned out to be considerably greater when the person giving viewed the act as a choice rather than a mandatory charitable action.
