“…Anecdotal participant reports pointed towards a third potential mechanism besides VR serving as a realistic dream environment and VR elements being incorporated into dreams: several participants within the VR group described mild to moderate feelings of dissociation following VR game exposure, which typically persisted for 1-2 h, and gradually diminished thereafter. Such dissociation symptoms are well known in the VR literature [15][16][17]: initially taken to be 'vertigo' or 'sea sickness' type effects, this phenomenon-referred to in the literature as 'VRISE'-is quite distinct from motion sickness [18] and remains poorly understood. Descriptions of VRISE overlap with and quite accurately describe the dissociative symptoms exhibited by participants-a conclusion supported by the psychological literature, which independently describes VR technology as a potent tool for inducing dissociated states for clinical applications [19,20].…”

Metacognitive reflections on one's current state of mind are largely absent during dreaming. Lucid dreaming as the exception to this rule is a rare phenomenon; however, its occurrence can be facilitated through cognitive training. A central idea of respective training strategies is to regularly question one's phenomenal experience: is the currently experienced world real , or just a dream? Here, we tested if such lucid dreaming training can be enhanced with dream-like virtual reality (VR): over the course of four weeks, volunteers underwent lucid dreaming training in VR scenarios comprising dream-like elements, classical lucid dreaming training or no training. We found that VR-assisted training led to significantly stronger increases in lucid dreaming compared to the no-training condition. Eye signal-verified lucid dreams during polysomnography supported behavioural results. We discuss the potential mechanisms underlying these findings, in particular the role of synthetic dream-like experiences, incorporation of VR content in dream imagery serving as memory cues, and extended dissociative effects of VR session on subsequent experiences that might amplify lucid dreaming training during wakefulness. This article is part of the theme issue ‘Offline perception: voluntary and spontaneous perceptual experiences without matching external stimulation'.

“…This is unexpected, because immersion and subsequent feelings of presence are considered to be key mechanisms for inducing real-life physiological, emotional, cognitive, and behavioral responses in virtual environments (Slater, 2018). Although there is consistent evidence that technological manipulations of immersion enhance feelings of presence (Wu et al, 2018), there is much less consistent evidence that enhanced presence initiates changes in performance (Lackey et al, 2016) and exposure therapy effects (Ling et al, 2014). Although tentative, when situations that are less complex, easier to understand, and relatively frequently encountered in real-life are modelled in VE, low immersive VE oftentimes perform as good as high immersive VE (Bowman & McMahan, 2007).…”

“…Spatial awareness acquired in a virtual environment has been shown to influence navigation and memory as participants who exhibit better viewing tend to have a higher sense of immersion (Wu et al 2019). VR fully immerses the user in the virtual environment by blocking other visual inputs that might disturb the experience; however, this level of presence can lead to the undesirable simulator sickness (Tyrrell et al 2018).…”

On the Use of Virtual Reality in Mitigating Hypothetical Bias in Choice Experiments

Choice experiments have been extensively used in many stated preference studies and disciplines. In order to give external validity to stated preferences, participants must behave the same in an experiment setting as they do in reality. The difference between a decision made in a real experiment and a hypothetical experiment is commonly attributed to "hypothetical bias." In this paper, we investigate whether virtual reality can reduce hypothetical bias in choice experiments. We conducted a set of experiments using the Food and Drug Administration's new Nutrition Facts Label for yogurts. Participants were randomly assigned to non-hypothetical and hypothetical experiments, which differed in terms of visual presentations of the product in question: text, picture, and a virtual grocery store. Given the absence of real markets for the new label at the time of the research, we approximate the real market with a binding choice in our non-hypothetical experiments. Our results suggest that although the hypothetical bias with virtual reality is not statistically significantly different from those using text or picture, it is the smallest. Among participants who did not exhibit high simulator discomfort, results suggest that virtual reality can significantly reduce hypothetical bias in choice experiments.
