Virtual Food Causes Stress in Patients Affected by Eating Disorders ScienceDaily (July 5, 2010) — Food presented in a virtual reality (VR) environment causes the same emotional responses as real food. Researchers writing in BioMed Central's open access journal Annals of General Psychiatry compared the responses of people with anorexia and bulimia, and a control group, to the virtual and real-life snacks, suggesting that virtual food can be used for the evaluation and treatment of eating disorders. 在虚拟实境中的食物也可以造成和真实食物一样的情绪反应。这篇发表在journal Annals of General Psychiatry的论文比较了厌食症、暴食症和控制组分别在虚拟以及真实环境中 享用下午茶，研究指出虚拟食物可以被用来评估与治疗饮食相关的疾病。 Alessandra Gorini from the Istituto Auxologico Italiano, Milan, Italy, worked with an international team of researchers to compare the effects of the exposure to real food, virtual food and photographs of food in a sample of patients affected by eating disorders. She said, "Though preliminary, our data show that virtual stimuli are as effective as real ones, and more effective than static pictures, in generating emotional responses in eating disorder patients." 研究刺激有真实食物、虚拟食物、照片。结果显示虚拟食物有着和真实食物相同的效果， 而且强度也比照片来的强。 The 10 anorexic, 10 bulimic and 10 control participants, all women, were initially shown a series of 6 real high-calorie foods placed on a table in front of them. Their heart rate and skin conductance, as well as their psychological stress were measured during the exposure. This process was then repeated with a slideshow of the same foods, and a VR trip into a computer-generated diner where they could interact with the virtual version of the same 6 items. The participants' level of stress was statistically identical whether in virtual reality or real exposure. 厌食症、暴食症以及控制组分别由10女性参与。会有六种高卡路里食物先摆在桌上并量测 心跳以及皮肤阻抗。接着会有图片的投影片播放以及可以互动的虚拟实境的食物，不论在 虚拟或者实境与食物接触，受试者都有相同的压力反应。 Speaking about the results, Gorini said, "Since real and virtual exposure elicit a comparable level of stress, higher than the one elicited by static pictures, we may eventually see VR being used to screen, evaluate, and treat the emotional reactions provoked by specific stimuli in patients affected by different psychological disorders." 虚拟食物也许可以帮助我们去监控、评估甚至治疗由食物引起的情绪反应的疾病。 -- 原始网址： http://www.sciencedaily.com/releases/2010/07/100705073924.htm 从实验法来看， 我比较好奇的是这研究似乎没有counter balance? 那这样可不可以说是先前的real food的exposure， 造成了後来VR food的效果。 --
