Social performance situations often constitute one of the most challenging communication tasks across different cultures. In today's work environments, giving presentations and performing in front of others are often essential and expected. Therefore, public speaking anxiety can have a serious impact on an individual's job performance, career choice, and prospects. Contemporary consumer virtual reality hardware has made it possible to practice public speaking anywhere in a safe and private virtual reality environment (VRE). As VREs offer the means to practice real-life scenarios, they also make it possible to go beyond what is "real"; to replace simulations with more dynamic and innovative training environments. Furthermore, with occupational life undergoing a significant shift toward technology-mediated working conditions, innovative tools and methods could also be used during virtually implemented real-time social interactions. This research aimed to study the ways in which an illusion of height, that is, perceived tallness versus perceived shortness, without any visible virtual body or representation, influences state speech anxiety and emotional responses of participants during simulation of a stressful speech task. The experiment followed a strictly controlled between-subject procedure, and both self-reported and psychophysiological data were collected. Results indicate that participants perceiving the illusion of tallness felt less anxious and had lower self-reported arousal compared with participants with the illusion of shortness. This implies that even simple, visual, first-person perspective manipulation of the VRE could help individuals to reduce their stress responses during a task-oriented situation.

感觉小还是站高？高度操纵影响虚拟现实中的言语焦虑和唤醒。

社交表演情境通常构成跨不同文化的最具挑战性的沟通任务之一。在当今的工作环境中，在他人面前进行演示和表演通常是必不可少的和期望的。因此，公开演讲焦虑会对个人的工作表现、职业选择和前景产生严重影响。现代消费者虚拟现实硬件使得在安全私密的虚拟现实环境 (VRE) 中随时随地练习公开演讲成为可能。由于 VRE 提供了实践真实场景的方法，它们也使超越“真实”成为可能；用更具活力和创新的培训环境代替模拟。此外，随着职业生活向以技术为媒介的工作条件发生重大转变，创新的工具和方法也可以在虚拟实施的实时社交互动中使用。这项研究旨在研究在没有任何可见的虚拟身体或表示的情况下，身高错觉（即感知的高与感知的矮）如何影响参与者在模拟压力性演讲任务期间的状态演讲焦虑和情绪反应。实验遵循严格控制的受试者间程序，并收集了自我报告和心理生理学数据。结果表明，与有矮小错觉的参与者相比，感知到高大错觉的参与者感觉不那么焦虑，自我报告的觉醒程度也较低。这意味着即使简单、直观、
