Abstract
This study utilizes an innovative experimental paradigm to investigate the effects
of virtual reality (VR) on dissociative experience and the sense of presence. A nonclinical
sample of 30 people were administered measures of dissociation, sense of presence,
and immersion before and after an immersion in a virtual environment. Results indicate
an increase in dissociative experience (depersonalization and derealization), including
a lessened sense of presence in objective reality as the result of exposure to VR.
Higher preexisting levels of dissociation and a tendency to become more easily absorbed
or immersed were associated with higher increases in dissociative symptoms resulting
from VR immersion. Results are discussed in terms of imaginative processes underlying
the dissociative experience and potential implications to the treatment of anxiety
disorders with VR.
