As virtual environments (VEs) become increasingly central to people's lives (Terry, 2002 Terry, F. 2002. New Media: An introduction, South Melbourne, , Australia: Oxford University Press. Google Scholar), understanding reactions to VEs may be as important as understanding behavior in the real world (Yee, Bailenson, Urbanek, Chang, & Merget, 2007 Yee, N., Bailenson, J. N., Urbanek, M., Chang, F. and Merget, D. 2007. The unbearable likeness of being digital: The persistence of nonverbal social norms in online virtual environments. The Journal of CyberPsychology and Behavior, 10: 115–121. Crossref, PubMed , Google Scholar). Immersive Virtual Environment Technology (IVET), which is now being used in psychological research (Blascovich et al., 2002 Blascovich, J., Loomis, J., Beall, A., Swinth, K., Hoyt, C. and Bailenson, J. 2002. Immersive virtual environment technology as a research tool for social psychology. Psychological Inquiry, 13: 103–125. Taylor & Francis Online, Web of Science ® , Google Scholar), can provide greater experimental control, more precise measurement, ease of replication across participants, and high ecological validity, making it attractive for researchers. It also can create links between researchers who study basic social psychological processes and those who study new media. In two studies we examined people's reactions as they navigated through a virtual world and interacted with virtual people, some of whom needed help. Participants' compassion and tendency to experience personal distress predicted emotional reactions (concern) and proxemic behavior (gaze orientation and degree of interpersonal distance) to a virtual person in need but not to a control person. The results support the use of IVET and proxemic variables to measure compassion unobtrusively and they encourage the use of IVET to advance our understanding of people's behavior in and reactions to virtual worlds and new media.
