For professionals in military and law enforcement domains, learning to regulate one's emotions under threatening circumstances is crucial. The STRESS project envisions a virtual reality-based system to enable such professionals to train their emotion regulation skills. To explore the possibilities for such a system, this article describes an experiment performed to investigate the impact of virtual training on participants' experienced emotional responses in threatening situations. A set of 15 participants were asked to rate the subjective emotional intensity of a set of affective pictures at two different time points, separated by 6 h. The participants were divided into three groups: the first group performed a session of virtual training in between, in which they received a choice-reaction task; the second group performed a session of virtual training, in which they had to apply reappraisal strategies; and a control group, that did not have any training session. The results indicate that the reappraisal-based training caused the participants in that group to give significantly lower ratings for the emotional intensity of the negative pictures, whereas the content-based training resulted in significantly higher ratings compared to the group without training. Moreover, a second experiment, performed with the same participants 6 months later, indicated that these effects are fairly persistent over time, and that they transfer to different pictures with similar characteristics.
对于军事和执法领域的专业人员来说，学会在威胁情境下调节自己的情绪至关重要。STRESS项目设想了一个基于虚拟现实的系统，以使这些专业人员能够训练他们的情绪调节技能。为了探索这种系统的可能性，本文描述了一项实验，该实验旨在研究虚拟训练对参与者在威胁情境中所体验到的情绪反应的影响。一组15名参与者被要求在两个不同时间点对一组情感图片的主观情绪强度进行评分，两个时间点间隔6小时。参与者被分为三组：第一组在两个时间点之间进行了一次虚拟训练，训练内容是一个选择反应任务；第二组进行了一次虚拟训练，训练中他们必须应用重新评估策略；还有一个对照组，没有进行任何训练。结果表明，基于重新评估的训练使得该组参与者对负面图片的情绪强度给出的评分显著更低，而基于内容的训练与未训练组相比，导致评分显著更高。此外，6个月后对相同参与者进行的第二个实验表明，这些效果随着时间推移相当持久，并且会转移到具有相似特征的不同图片上。
