Experiencing Organ Failure in Virtual Reality: Effects of Self- Versus Other-Embodied Perspective Taking on Empathy and Prosocial Outcomes

This study capitalizes on the unique capability of virtual reality (VR) to examine the efficacy of self- versus other-embodied perspective taking in promoting kidney donation in Singapore. The study used a 2 (self- vs other-embodied) × 2 (mirror vs photo presentation) between-subjects VR experiment ( N = 128), wherein participants played the role of a patient needing a kidney donation, either as themselves or as a typical organ-failure patient. Our findings showed that self-embodied perspective taking triggered self-oriented emotions (i.e. personal distress) and subsequently egoistic motivations that resulted in alternative prosocial behaviors (e.g. monetary donation, volunteering) than kidney donation. We found that embodying the other, rather than the self, had the practical benefit of inducing other-oriented emotions (i.e. empathy) and hence altruistic motivations that promoted kidney donation. This study clarified the conditions under which embodied perspective taking promoted different prosocial outcomes, and the specific mechanisms through which it achieved those outcomes.
