“…Neither embodiment nor presence was examined and only 15 subjects per condition were surveyed. Landau et al (2020) showed that young adults who were embodied in a virtual body of a child using 180°stereoscopic video significantly overestimated the duration of the VR experience compared with a control group embodied in a virtual body of their own age. Furthermore, after exposing participants to a VR experience, Bansal et al (2019) observed a novel relationship between action and event speed that resulted in a recalibration of time perception in a psychophysical task.…”

Psycho-pathological conditions, such as depression or schizophrenia, are often accompanied by a distorted perception of time. People suffering from this conditions often report that the passage of time slows down considerably and that they are “stuck in time.” Virtual Reality (VR) could potentially help to diagnose and maybe treat such mental conditions. However, the conditions in which a VR simulation could correctly diagnose a time perception deviation are still unknown. In this paper, we present an experiment investigating the difference in time experience with and without a virtual body in VR, also known as avatar. The process of substituting a person’s body with a virtual body is called avatar embodiment. Numerous studies demonstrated interesting perceptual, emotional, behavioral, and psychological effects caused by avatar embodiment. However, the relations between time perception and avatar embodiment are still unclear. Whether or not the presence or absence of an avatar is already influencing time perception is still open to question. Therefore, we conducted a between-subjects design with and without avatar embodiment as well as a real condition (avatar vs. no-avatar vs. real). A group of 105 healthy subjects had to wait for seven and a half minutes in a room without any distractors (e.g., no window, magazine, people, decoration) or time indicators (e.g., clocks, sunlight). The virtual environment replicates the real physical environment. Participants were unaware that they will be asked to estimate their waiting time duration as well as describing their experience of the passage of time at a later stage. Our main finding shows that the presence of an avatar is leading to a significantly faster perceived passage of time. It seems to be promising to integrate avatar embodiment in future VR time-based therapy applications as they potentially could modulate a user’s perception of the passage of time. We also found no significant difference in time perception between the real and the VR conditions (avatar, no-avatar), but further research is needed to better understand this outcome.

“…The choice of shooting the scene from an over-the-shoulder angle was to clearly emphasize the identity of each perspective. It is technically possible to create the illusion of first-person embodiment using 360° video techniques by placing the camera at an actor’s eye level (Aitamurto et al, 2018; Landau et al, 2020). If the scene was filmed from a first-person perspective, that is, “virtually embodying” participants in the actors’ body, they would not have known whom they represent.…”

We present an experimental study conducted in the context of the Israeli–Palestinian conflict that examined the effect of immersive 360° video on inducing a more critical perception of the ingroup’s actions in the conflict. An immersive experience of a simulated conflict scenario filmed from the outgroup’s point of view led to the judgment of the ingroup actors’ behavior as less moral and less justified compared to watching the same scenario as a two-dimensional video. This effect was not mediated through increased outgroup perspective-taking and empathy but through higher levels of hostile emotions toward the ingroup actors, which in turn were influenced by an increased sense of presence and engagement in the immersive experience. These findings provide initial evidence for the still widely unexplored potential of virtual reality as a new method for conflict resolution.

“…Communication with the world happens here, not at the meninges (as the boundaries of the brain) or an ephemeral "soul. " So close is the link to outer experience that virtual reality can, at least on the short term, trick us into illusionary body experiences (Landau et al, 2020).…”

Evidence-based recommendations for lifestyles to promote healthy cognitive aging (exercise, education, non-smoking, balanced diet, etc.) root in reductionistic studies of mostly physical measurable factors with large effect sizes. In contrast, most people consider factors like autonomy, purpose, social participation and engagement, etc. as central to a high quality of life in old age. Evidence for a direct causal impact of these factors on healthy cognitive aging is still limited, albeit not absent. Ultimately, however, individual lifestyle is a complex composite of variables relating to both body and mind as well as to receiving input and generating output. The physical interventions are tied to the more subjective and mind-related aspects of lifestyle and wellbeing in the idea of the “embodied mind,” which states that the mind is shaped by and requires the body. The causality is reciprocal and the process is dynamic, critically requiring movement: the “embodied mind” is a “embodied mind in motion.” Hiking, playing musical instruments, dancing and yoga are examples of body–mind activities that assign depth, purpose, meaning, social embedding, etc. to long-term beneficial physical “activities” and increase quality of life not only as delayed gratification. The present motivational power of embodied activities allows benefiting from the side-effects of late-life resilience. The concept offers an access point for unraveling the mechanistic complexity of lifestyle-based prevention, including their neurobiological foundations.
