Michael McCullough


Michael McCullough is an experimental psychologist who is concerned primarily with the cognitive foundations of human sociality. In addition to his pioneering work on forgiveness, gratitude, prosocial behavior, and morality, for twenty years he has studied the effects of empathy on how we treat others. Additionally, McCullough has also worked in recent years to shed light on scientific puzzles about self-control and about the social effects of a mammalian hormone known as oxytocin.
