In this study, we examined retrospective judgments of the passage of time (PoT) in 56 patients with Parkinson’s disease, compared to 53 age-matched healthy participants, to evaluate whether interoceptive perceptions or psychological representations of the self were responsible for these judgments. Participants rated their perception of the passage of time using 7-point Likert scales for distant life periods (5–10 years ago). They also compared their current feeling about the passage of time with how they remembered feeling during those past periods, and they evaluated their recent experience of time passing (over the past week, days, and months). Then, they completed short scales assessing their emotional states, perceived health, well-being, and feelings of happiness. Finally, they completed the Dambrun & Ricard (2001) scale assessing the psychological dimension of self-transcendence. Our results confirmed that the passage of time related to long past periods and the current feelings of PoT are two distinct dimensions of retrospective feelings about time. The former is related to the dimension of self-consciousness linked to self-projection across the lifespan. The latter depends on representations of bodily states and emerges from perceived health, present well-being, and emotional state. Finally, Parkinson’s disease itself did not alter the judgment of PoT related to either the present self or the projected self. Self-transcendence strongly modulated the perception of both the present and future self, and significantly influenced PoT judgments in both patients and healthy participants.
