Prior research has explored the impact of virtual reality (VR) on human time perception without definitive conclusions. To enhance understanding, we replicated a seminal study, refining it and introducing novel variables. Building upon the original study, we investigated the influence of virtual sun speed and cognitive workload on time perception in a VR environment. Our experiment involved 70 participants estimating time intervals under varying cognitive demands. In addition to assessing time perception during immersion, we examined post-VR time estimations. Contrary to the original study, virtual sun movements did not affect time judgments in VR. However, cognitive workload had a consistent effect, which is consistent with previous findings. Notably, VR immersion affected post-VR time perception of short intervals, a previously overlooked aspect. We contribute to the field by deepening the understanding of time perception dynamics during and after VR experiences and refining earlier findings through replication.
