本研究的目的是测试在虚拟现实（VR-MIP）环境中情绪诱导程序的效果，以诱导放松和产生存在感，并测试触觉和嗅觉的刺激是否能提高VR-MIP的效果。采用四种实验条件进行对照研究。所有的实验都包括VR-MIP来诱导放松，但刺激的感官不同。样本由136名参与者组成，他们被随机分配到四种实验条件中的一种。对情绪和存在感进行评估。结果显示，情绪诱导前后存在统计学差异，各组均有较高的存在感。然而，在情绪和存在感方面，四组之间没有统计学差异。结果表明，VR-MIP是有效的；然而，刺激触觉和嗅觉对情绪诱导和存在感没有明显的改善。研究发现，触觉受到刺激的人群更有优势，他们看起来更放松，存在感也更高。我们假设在使用VR-MIP时，刺激触觉可以提高效果，因为它提供了更多的感觉信息。(C) 2015 Elsevier Ltd.版权所有。
The aim of this study was to test the efficacy of a mood-induction procedure in a Virtual Reality (VR-MIP) environment for inducing relaxation and generating sense of presence, and to test whether the stimulation of the senses of touch and smell improves the efficacy of this VR-MIP. A controlled study was carried out with four experimental conditions. All of them included the VR-MIP to induce relaxation, but varying the senses stimulated. The sample consisted of 136 participants randomly assigned to one of the four experimental conditions. Emotions and sense of presence were evaluated. The results showed statistical differences before and after mood-induction and a high sense of presence in all groups. However, no statistical differences were found among the four groups on emotions and sense of presence. The results showed that the VR-MIP was effective; however, the stimulation of the senses of touch and smell did not show significate improve of the mood-induction or the sense of presence. It was identified a trend in favor of the groups where the sense of touch was stimulated, they seemed more relaxed and the sense of presence was higher. We hypothesized that the stimulation of sense of touch, could improve the efficacy when using VR-MIP because it provides more sensory information. (C) 2015 Elsevier Ltd. All rights reserved.
