Virtual reality could help people lose weight, fight prejudice
Date:11/6/2012

Internet-based interactive games and social media outlets have become intertwined with the physical realities of millions of people around the world. When an individual strongly identifies with the cyber representation of themselves, known as an avatar, the electronic doppelganger can influence that person's health and appearance, according to a University of Missouri researcher's study. Harnessing the power of the virtual world could lead to new forms of obesity treatment and help break down racial and sexual prejudices.

"That alter-ego can then have a positive influence on a person's life. For example, people seeking to lose weight could create fitter avatars to help visualize themselves as slimmer and healthier."

In Behm-Morawitz's study, 279 users of a virtual reality community, Second Life, answered a questionnaire about their engagement with their avatar and relationships they developed online, as well as their offline health, appearance and emotional well-being. Self-presence, or the degree to which users experienced their avatars as an extension of themselves, was found to predict the influence of the avatar on people's physical reality. A strong sense of self-presence in the social virtual world positively promoted health and well-being of study participants. People with high degrees of self-presence in the cyber world reported that their experience with their avatar improved how they felt about themselves offline. Self-presence also correlated to greater satisfaction with online relationships.

"This study found no evidence of negative effects of a high degree of self-presence in the virtual world on study participants; however, that doesn't rule out the possibility," said Behm-Morowitz. "Users should practic
