Short-lasting post-effect of immersion in virtual tilted room on verticality perception

Résumé

Immersion in a virtual tilted room (VTR) strongly modulates the visual vertical (VV). In view of a possible clinical application in patients with a tilted verticality representation, the existence of a post-effect must be explored. We immerged 43 healthy individuals for 10-15 minutes in virtually tilted environments (18° leftward or rightward). VV was measured before, during, and after VTR (immediately or after 6 minutes). During VTR, VV was tilted congruently to the environment (mean 12 ± 3°). A light post-effect was observed after Left-VTR only (mean= -1.1 ± 1.2° ; difference from zero; p=.01), but no effect lasted at 6 min. VV adaptation to VTR is fast. The lack of remaining post-effect might compromises the clinical application of the VTR, if patients behave similarly. It may be not if their internal model of verticality is spontaneously altered. The next step will be to test patients.
