You seem beside yourself:  dissociation, sense of presence,  and interoceptive processes  reflected in HRV activity

Depersonalisation /Derealisation (DP/DR) has been an object of interest in clinical psychology for many years, with its exact causes still uncertain and debated. As part of a pilot study for a larger study, this paper attempts to integrate information from previous studies to link DP/DR to disrupted interoceptive processes, indicated through a disruption in the sense of presence in the real world and decreased heart rate variability (HRV). By using a virtual reality (VR) experience to induce an altered state of consciousness, data from questionnaires and electrocardiogram (ECG) measures were used to determine the relations between the sense of presence and HRV, depending on whether attention was directed, or the participant was allowed to fully immerse themselves in the experience. While no significant results were found, the limitation of a small sample size does not necessarily imply the rejection of the theoretical assumptions shaping the proposed hypothesis, and trends in the...Show moreDepersonalisation /Derealisation (DP/DR) has been an object of interest in clinical psychology for many years, with its exact causes still uncertain and debated.
