The Effect of Exposure to VR vs. 2D Virtual Environments on Restorativeness: The Mediating Role of the Sense of Presence

Virtual reality (VR) finds many fields of application due to its capability to reproduce "in virtuo" real environments. Previous studies highlighted that exposure to virtual environments leads to restorativeness, which in turn is related to several positive psychological outcomes. However, the mechanisms that lead to restorativeness are still unclear. The main aim of this study was to investigate the mediating role of the sense of presence in the relationship between exposure to virtual environments and restorativeness. We conducted a study with a 2 x 2 between-subjects design. Two conditions (archaeological vs. natural sites) were presented on two levels (2D vs. VR), on a sample of 199 participants (Mage = 22.49, SD = 7.22, range = 18-69). Results show a significant indirect effect of the sense of presence generated by VR on restorativeness, regardless of the condition presented. Our findings shed light on the underlying mechanisms of restorativeness enhanced by virtual environments. Limitations of the study, research developments, and practical implications are discussed.
