Abstract
Depersonalization and derealization are characterised by feelings of detachment from one’s bodily self / surroundings and a general emotional numbness. We explored predisposition to trait-based experiences of depersonalization / derealization-type experiences and autonomic arousal toward simulated body-threats, which were delivered to the participant’s own body (i.e. Self) and when observed being delivered to another individual (i.e. Other). Ninety participants took part in an “Implied Body-Threat Illusion” task (Dewe, Watson, & Braithwaite, 2016) and autonomic arousal was recorded via standardised skin conductance responses and finger temperature. Autonomic suppression in response to threats delivered to the Self correlated with increases in trait-based depersonalization-type experiences. In contrast, autonomic suppression for threats delivered to Others correlated with trait-based derealization-like experiences. Body-temperature and anticipatory arousal did not correlate reliably with predisposition to depersonalization- or derealization-type experiences. The theoretical implications of these findings are discussed in terms of a fronto-limbic autonomic suppression mechanism.
