Abstract

Our perception and cognition are susceptible to We are subject to the environment of the outside world. The virtual reality (VR) environment, which has been widely used in recent psychological studies, allows us to create the atypical environment that cannot be realized in the real world, and hence it is effective for examining cognitive performances under the atypical environment. In the present study, we focused on the speed of time passage which is invariable in the real world and investigated psychological and cognitive effects of temporal modulation of immersive VR environment. In the experiment, VR videos of sightseeing guidance were presented for approximately 3 minutes using immersive head mount display (HMD) VR device. The playback speed was manipulated to 1.5 times (fast) or 0.6 (slow) speed; thus the participant adapted to the atypical environment wherein the time passage was slow or fast. After viewing the video, the participants engaged in the response time task, the tapping task to press the button at 1 second interval, the time perception task that asked the participants to estimate the elapsed time for watching the video, and some questionnaires that asked the fatigue, feelings, thoughts on the past and future. The results showed that change of the speed of time passage did not have a great influences on the psychological and cognitive task, while, the manipulation may affect the subjective evaluation on future.
