To navigate and accomplish changes within the environment, a sense of time is necessary. Studies show that our perception of time is affected by the movements we perform (De Kock, 2021). However, time perception, like most cognitive processes, is studied mostly under conditions where the movements of experimental participants are restricted. The increasing sophistication of technologies such as virtual reality or augmented reality (AR) allows for the investigation of cognitive processes under different behavioural states (Nilsson et al., 2018). The planned study aims to investigate differences in time perception while participants are standing or walking through space. The experiment involves participants estimating the duration of visual stimuli presented in different locations within the visual field of AR glasses. Participants are presented with a visual stimulus in one of five locations (middle, upper, lower, right, and left sides) of the screen. The visual stimulus appears on the screen for durations of 200, 400, 600, or 800ms. Participants then judge the duration of the visual stimulus appearance. The task will be completed while participants are standing still or while they are walking. We are interested in seeing if duration estimation will differ between locomotive states. Furthermore, given the link between space and time perception (Sima & Sanayei, 2024), we want to see if the location of stimulus appearance affects duration estimation, as the location of stimuli in the visual field tends to correspond to different spatial distances (e.g., objects in the lower hemifield tend to be closer).
