Virtual empowerment: manipulating height in virtual reality affects self-related cognitions and personal speech performance evaluation

Abstract

Social performance situations, often crucial and expected in today's work contexts, can be perceived as highly challenging and stressful. Therefore, experiencing anxiety in public speaking situations can have a negative impact on individuals' working lives and career prospects. Virtual reality environments offer novel means to practise public speaking anywhere, safely and privately, and to replace simulations with more dynamic and innovative training environments unavailable in real-life scenarios. Additionally, these innovative tools and methods could also be used during virtually implemented real-life interactions as working conditions are increasingly shifting towards more technology-mediated forms. This research investigates the potential for a virtual reality height manipulation (i.e. raised or lowered point-of-view) to influence individuals' self-statements during a stressful speech task and, subsequently, their personal performance evaluation. Results of a strictly controlled, between-subject experiment indicate that participants perceiving themselves taller evaluated their speech performance more positively and experienced fewer negative self-statements during the speech task. Furthermore, perceived tallness was associated with lower levels of public speaking anxiety. These results suggest that even a simple, visual first-person perspective manipulation of virtual reality environment influences individuals' personal evaluation of their own performance and potentially helps them improve their task-related cognitive processes.
