Abstract

Addressing the rising obesity prevalence, a Virtual Reality full-body illusion as a novel approach to obesity prevention is examined, allowing individuals to experience ownership of a virtual body (VBO). Although never tested, an immersive experience of a virtual self that suffers from the consequences of an unhealthy lifestyle, like an overweight body, may motivate health behaviors to avoid these consequences. Hence, the study aimed to investigate 1) whether experiencing the consequences of unhealthy snacking could increase healthy snacking intentions and -intake; 2) perceived threat as potential mechanisms of this effect; and 3) potential facilitators and inhibitors of VBO (i.e., avatar body size, visuotactile stimulation/VTS and facial similarity), and whether these factors could enhance effects on perceived threat, healthy snacking intentions and -intake.

Employing a 2 (Experiencing consequences: yes vs. no) ×2 (VTS: congruent vs. incongruent) ×2 (Facial similarity: similar vs. generic) between-subjects design (N = 229), findings revealed that experiencing consequences increased individuals’ healthy snacking intentions and healthy snack intake, but only through perceived severity. Furthermore, embodying an overweight avatar inhibited VBO, while congruent VTS facilitated VBO. The study provides valuable insights into the Virtual Reality experiences, paving the way for innovative research avenues in health communication and behavior change tools.

塑造超越现实的健康行为:体验不健康零食后果的全身幻觉
针对肥胖症发病率不断上升的问题,我们研究了虚拟现实全身幻觉作为预防肥胖症的一种新方法,让人们体验虚拟身体(VBO)的所有权。虽然从未进行过测试,但身临其境地体验一个遭受不健康生活方式后果(如身体超重)的虚拟自我,可能会促使人们采取健康行为来避免这些后果。因此,本研究旨在调查:1)体验不健康零食的后果是否会增加健康零食的意向和摄入量;2)感知到的威胁是产生这种效果的潜在机制;3)虚拟身体的潜在促进因素和抑制因素(即:虚拟人的体型、视觉图标、虚拟人的身体大小、虚拟人的体重、虚拟人的体重、虚拟人的体重、虚拟人的体重、虚拟人的体重、虚拟人的体重、虚拟人的体重、虚拟人的体重)、采用 2(体验后果:是 vs. 否)×2(视觉刺激:一致 vs. 不一致)×2(面部相似性:相似 vs. 一般)的受试间设计(N = 229),研究结果显示,体验后果会增加个体的健康零食意向和健康零食摄入量,但只是通过感知到的严重程度。此外,化身为超重的化身会抑制健康零食摄入,而一致的 VTS 则会促进健康零食摄入。这项研究为虚拟现实体验提供了宝贵的见解,为健康传播和行为改变工具的创新研究铺平了道路。
