This helped the aides understand, for instance, why her mother ate only the food on the right side of her plate. Later, earning a master's degree in biomedical visualization, Shaw used virtual reality to help health care providers feel what their patients felt. She founded Embodied Labs in And if they take 30 minutes and put on the goggles and run through it and have even just a little sense of an understanding, just think of the change we might be able to make.
As part of a geriatrics class, students can shadow hospice nurses for 48 hours. Nguyen said "Clay" made her think more about what dying patients might comprehend as they're slipping away. I think this lab really does that. Not everyone believes that virtual reality is beneficial.
The initial experience might cause viewers to believe blind people are less capable than they are. Empathy, he argues , can be manipulated: A simulation could create empathy for a Syrian refugee — or for a man, "standing hungry in a food line," because a Syrian refugee took his job. As the Russian news agency TASS reports, a year old man from Moscow was found dead in his apartment this week from what is believed to be the first VR-related death.
As promising new advancements in augmented and virtual reality are made, stories like this one underline the need for a greater emphasis on safety and security while using these devices.

Community Activity Refresh. Trending Stories. See Table 1. Body ownership was high throughout the exposures, in line with previous findings that first person perspective over the virtual body and visuo-motor synchrony provides powerful cues for this illusion. Fig 10 shows the responses, and that even in the first periods when the participants were with a child-like form and the last period when they appeared old and frail the body ownership scores were high.
Fig 10D shows that participants experienced the movements of the virtual body as their own, so that the setup was successful in this regard. A For mirror. B For down. C For mybody. D For mymovements. Overall participants experienced the illusions of being in the Island environment, with their virtual body as their own. They liked and collaborated well with the other participants, with very few incidents of discomfort. Table 2 shows summaries obtained from the posterior distributions of the parameters of the model Eq 1. However, the posterior probability that the Experimental group had greater lifechanges exceeds 0.
The goodness of fit plots are shown in S3 Text. The first six columns show the means and standard deviations, 2. The seventh column shows the posterior probability of the parameter being positive. In the parameters the 0 entry e. The subscales meaning , selfacceptance , and others show the clearest differences, with those in the Experimental group having greater scores than those in the Control group.
One premise of this research is that a high level of body ownership over the several sessions can enhance the effectiveness of the scenario as it relates to personal death. Therefore it is interesting to consider the impact of body ownership on the four response variables. In order to create one overall score we averaged all the scores over the three variables mirror , down , mybody over the last 3 sessions the result is almost identical to extracting the first component from a factor analysis.
We refer to this as meanownership. In addition according to TMT the critical variable should be death anxiety fod. Therefore, we examine a new model, restricted to the experimental group only, where we consider the influence of both meanownership and fod. In the model shown in Eq 2 , O refers to meanownership and F to fod. We use the same prior distributions as for Eq 1. From the FOD block we can see the fod is not related to meanownership. The iat is negatively associated with meanownership the posterior probability that the coefficient is negative is 0.
The tmt is positively associated with fod , but there is not very strong evidence that it is related to meanownership. Finally there is strong evidence that lifechanges is positively related both to meanownership and fod. Goodness of fit results are shown in S3 Text. Overall these goodness of fit tests show that the models above do not explain at all the variation in fod , being unrelated to Condition and selfesteem Eq 1 and unrelated to body ownership Eq 2. Although the Island experience was designed to be a positive one, involving participants carrying out tasks with compatriots in a beautiful island setting, it may be thought that the portrayal of the deaths of their compatriots, and finally their own personal death, would lead to unpleasant feelings.
Fifteen days after their final exposure participants were sent an email that had three questions with the results shown in S1 Table , based on the 17 responses received, almost all positive. These reports suggest that participants on the whole did not have unpleasant or distressful experiences. Unlike almost all other research in the area of presence Place Illusion and Plausibility and body ownership in VR, participants were exposed multiple times, and the results showed that these illusions were strongly experienced throughout. Place Illusion has been argued to rest on the foundation of natural sensorimotor contingencies for perception [ 17 ].
In this case participants perceived through a stereo wide field-of-view head-mounted display albeit with relatively low resolution with 6 degrees of freedom head-tracking. The events on the Island and the narrative were sufficient to maintain a high degree of Plausibility questionnaire variables real and happening —in particular Plausibility has been argued to rest on the environment responding to the actions of the participant, events that directly and personally relate to the participant—both of which were strongly represented in the Island scenario.
The third requirement of Plausibility is that when the environment depicts something that occurs in reality then it should conform to expectations. Nevertheless all the elements of the scenario were internally consistent and coherent, which has been shown to be another requirement for Plausibility [ 59 ]. Body ownership was high throughout, in spite of the virtual body being humanoid but not human, and at various different ages.
This supports other findings that adults can have a strong illusion over a virtual child body [ 39 ] or even a Barbie doll [ 60 ], a different raced body [ 25 , 61 ] including a purple coloured body [ 23 ]. The first person perspective [ 62 ] and multisensory integration [ 58 ], and especially visuomotor synchrony between body movements and movements of the virtual body [ 63 ] all contribute to the illusion of body ownership. What is especially new here is that we showed that the illusion was sustained over multiple exposures.
The level of co-presence, the illusion of being with others, was high throughout, and the others were experienced as being likeable, and doing enjoyable tasks together. All of the above elements were essential to our main goal of creating a fantastic strange alternate reality that people would come to take as an alternative life, that they would then experience leaving once and for all, after having the simulated death experience.
The results show that these elements were realised successfully. The measure of death anxiety fod was not influenced by Condition Control, Experiment , selfesteem Table 2 nor the level of body ownership Table 4. In [ 27 ] we found that a type of virtual out-of-body experience did result in a reduction of fear of death. That was a single issue study where there was just one factor manipulated—the precise method by which the out-of-body experience was generated. The present study has multiple elements—seeing the death of others, the out-of-body experience, the simulated NDE and all the social interactions and events that had happened beforehand.
Also in [ 27 ] the fear of death was assessed straight after the VR experience whereas in this case one day later. Therefore it is not too surprising that the same result was not obtained. The first six columns show the means and standard deviations, 5 th , 50 th , and 95 th percentiles of the posterior distributions of the parameters of the model.
The iat , however, was negatively associated with body ownership Table 4. Peck, Seinfeld, et al. Moreover, there was positive contact throughout with the other characters who were also of the same species, though different colours. The relationship between TMT and self-esteem is a complex one. When self-esteem is manipulated within an experiment, i. Similarly if implicit measures of self-esteem are used e.
The argument is that such self-esteem acts as an anxiety buffer thereby modulating the effects of mortality salience. However, as noted in [ 9 ] those studies that used the self-report Rosenberg scale to measure self-esteem find the opposite effect, that higher self-esteem is associated with an enhancement of the mortality salience effect. Moreover, high self-reported esteem may not really measure just self-esteem but rather express other factors including narcissism and insecurity, for which Burke, Martens, et al.
Also supporting the idea of Terror Management Theory is the positive association between tmt and fod Table 4 : in other words the more people were inclined to support their nation the greater their fear of death subsequent to the experiment. The life changes inventory lifechanges tended to be higher for those in the Experimental compared to the Control group Table 2.
Moreover, Table 4 shows that the lifechanges score was positively associated with both body ownership and fear of death. It was highly interesting to note that participants were never explicitly trained to carry out the tasks or the ceremony at the death of one of the partners. This knowledge was introduced by the first confederates acting as participants in the early phases of the experiment, and then handed down the generations, so that by the time there were no confederates remaining the participants were managing themselves with the older ones guiding the younger ones.
Anecdotally, when the participants finally met together days after the experiment in an overall debriefing meeting S8 , this was a quite emotional reunion. Recall that they had never met physically, and knew nothing about one another, not even that they were all women. Participants exchanged stories of their time in the Island and shared their experiences and feelings with one another and the experimental facilitator. This, together with the results of their post experimental interviews, and reports from the daily diary kept by participants, will be the subject of a further report.
As mentioned in Section 4. Nevertheless, there are important ethical issues in using VR for experimental studies, as discussed by Madary and Metzinger [ 66 ]. In the current study the environment and most experiences were designed to be pleasant, participants were able to leave at any time without giving reasons, they gave informed consent, and vulnerable people were excluded. In our experiment participants were actually shown how to construct a monument to remember their partners who had died, so that they were indeed respected.
We have seen in this and other studies that VR may lead to changes in implicit attitudes and behaviours in participants. Up to now, to our knowledge, this has only been for what most would consider as positive reasons—e. In this experiment such changes were concerned with attitudes towards self-acceptance or caring for others, again positive changes. Unfortunately, the same methodology could be used for malfeasance and this applies to any technology. Researchers have the duty to be aware of and to guard against such a possibility. Although our research is based on the premise that NDEs are generally associated with positive life changes, it should be noted that this is not always the case.
For example, OBEs may involve seeing a double of oneself he-autoscopy which can be particularly disorienting and terrifying—see the case report in [ 69 ]. A small number of distressing experiences were reported by burns survivors who experienced NDEs, but most do report positive NDEs [ 37 ].
Given the complexity of this experiment, both with respect to producing the software involved, the logistics of the study, the resources available, and that this was the first time that anything like this has ever been done, the sample size was inevitably small. In the Bayesian analysis we have used high variance prior distributions in fact the Cauchy distribution used for the parameters has infinite variance and yet we nevertheless found posterior probabilities indicating possible relationships.
It is important, nevertheless, to be aware of the limitations of this study. The experiment needs to be repeated with a greater sample size, and also should include men as well as women, and various ages. The experiment was particularly complex, and our goal was to demonstrate the fundamental idea and methodology and to show that this was feasible. Hence, we only included women since this removed one element of possible variation that might have been introduced were both sexes to have been included.
The important point of this paper is that we have shown that it is possible to utilise virtual reality for studies involving death, even personal death, and we hope that this has opened up an exciting new field in which others can follow. The approach that we have adopted has wider implications. For example, when making a critical life decision, such as whether or not to have a child, we cannot know how that would be without actually having the experience.
We typically imaginatively project ourselves forward into possible futures, and try to evaluate the possible outcomes of different decisions. However, this is especially complex since the experience itself may fundamentally change us, so that the way we evaluate the results of that decision while living its consequences may be quite different from any prior evaluation based on imaginal future projections. Our experiment points to the possibility for people to gain insight into such transformative experiences through simulation of alternate futures. The technology is not available yet to offer personalised experiences constructing such environments today remains significant team work over extended periods of time , but a system for personalised VR experiences useful for decision making is a capability worth pursuing.
Some individual defining characteristics such as age and religion have been removed for data protection reasons.

Abstract Mortality is an obvious if uncomfortable part of the human condition, yet it is impossible to study its impact on anyone who experiences it. Introduction Understanding the experience and impact of death from a scientific point of view is problematic since the people who experience it are, of course, no longer around to report about what happened.

Fig 5. The shared virtual environment. The collaborative tasks To keep the participants occupied and entertained, and to reinforce the social bond between them, we designed several collaborative tasks that were available in every session.
There were three main types of tasks, with two variations each, which formed six different tasks: Classification task : In this task, there were two baskets and some objects nearby.

Fig 7. The ceremony. Data collection Daily, after their VR session, each Experimental participant completed a post-trial questionnaire on presence, evaluation, body ownership and agency see next section and was interviewed. Response variables There were several categories of response variable: those providing background information, presence and body ownership, death anxiety, Terror Management Theory and a life changes inventory. Table 1 The post-trial questionnaire on presence, evaluation, body ownership and agency. Variable name Question Presence there I had the sensation of being in the virtual world.
Evaluation friendly I felt that the other beings were friendly towards me. Body ownership and agency mirror Although the body that I saw in the mirror did not look like me I had the sensation that it was my body. Statistical methods The goal was to examine whether there are differences between the Control and Experimental groups on the four response variables: fear of death fod , the Terror Management Theory measure tmt , the Implicit Association Test for racial bias iat , and most important, the life-changes inventory lifechanges.
