Can an avatar that resembles you influence your behavior? There is growing evidence suggesting just that. Manipulating an avatar’s appearance to resemble an individual is now possible. Jeremy Bailenson at Stanford University found that college students reported increases in exercise 24 hours after viewing an avatar resembling them exercising. We investigated whether these findings translate into physical activity gains in sedentary, overweight veterans. We objectively assessed veterans’ levels of physical activity with accelerometers. We randomly assigned them into 1 of 3 groups: viewing an avatar that looked like them exercising, another viewing an avatar of another person exercising, and a third to watch a static figure exercising. Veterans who viewed an avatar resembling themselves exercising significantly improved their physical activity 1 week after the intervention. (http://www.ncbi.nlm.nih.gov/pubmed/22357026) [More]
