In the past decade, there has been a growing amount of research on so-called self-transcendent emotions, mainly in the domain of positive emotions. However, most candidate self-transcendent emotions (e.g., Awe, Gratitude, Being Moved, Wonder) have been studied in isolation, leaving the commonalities and the differences of their phenomenology unknown. In the present paper, we sought to identify the phenomenological nature of main families of self-transcendent emotions. We drew on two large datasets ( N ₁  = 3,113; N ₂  = 1,443) in which participants had to recall an emotional episode or to watch emotional videos and had to report their emotions through a list of 40 emotion labels. Participants were also presented with a large list of items probing their cognitive appraisals, bodily feelings, and action tendencies. Using a principal component analysis, we identified three main dimensions of positive emotions: hedonic, social, and epistemic states. Candidate self-transcendent emotions were distributed across two dimensions, suggesting that at least two main different families of self-transcendent emotions should be distinguished. Our results also allowed us to identify self-reported cognitive appraisals, bodily feelings, and action tendencies characteristic of each family.
