Introduction. Depersonalization (DP) is a common condition characterized by distressing feelings of estrangement from the self and the external world. Unlike schizophrenia, peripersonal space is preserved in DP, yet altered time perception are also observed. This asymmetry needed to be further investigated by considering DP facets in spatiotemporal experiences.
Methods. An online study was conducted (N = 1034) investigating the association of HIGH DP traits measured by the Cambridge Depersonalization Scale (CDS score > 50) with altered subjective experiences of body, time, and space.
Results. The results demonstrated associations between DP scores and distorted experiences of time, body and space. When shared variance between CDS facets is considered, the facet “Anomalous Body Experience”, appears as main predictor of spatiotemporal alterations, associated with subjective experience of time slowing down.
Conclusion. These results echo phenomenological experiences of spatiotemporal disruption in DP and suggest that these experiences may mainly come from estrangement experiences from the bodily self. Our work calls for further investigations linking DP to disruption of internal/external clock, in relation to active movements in the world.
