In this article we review the emerging literature on the self-transcendent emotions. We discuss how the self-transcendent emotions differ from other positive emotions and outline the defining features of this category. We then provide an analysis of three specific self-transcendent emotions—compassion, gratitude, and awe—detailing what has been learned about their expressive behavior, physiology, and likely evolutionary origins. We propose that these emotions emerged to help humans solve unique problems related to caretaking, cooperation, and group coordination in social interactions. In our final section we offer predictions about the self-transcendent emotions that can guide future research.
