This study examined whether the time perception can be manipulated by presenting periodic tactile vibration. Previous research suggested that the vibration frequency (at around 1 Hz) applied while people are sitting passively distorts the perceived speed of time; higher frequencies make us perceive the passage of time faster than lower frequencies. (Iizuka & Yotsumoto, 2019). In this study, we presented vibration while participants were actively engaged in a task. After engaging in a task for 7.5 min, participants reported the subjective speed of the time passed, the amount of boredom during the task, and the estimated length of the time using a visual-analogue scale. In Experiment 1, participants solved arithmetic problems. Subjects were randomly assigned to one of three vibration conditions: none (control), 54 beats per minute (BPM), or 66 BPM. In Experiment 2, to investigate whether the effect of vibration stimuli is influenced by attention, participants counted the number of vibrations, with 54 BPM and 66 BPM assigned between subjects. In both experiments, significant negative correlation was found between perceived duration of time and the amount of boredom, replicating Witowska et al. (2020). However, neither perceived duration nor the subjective speed of time differed across vibration conditions, indicating no detectable effect of the tactile stimulation. These findings suggest that vibration-based modulation of time perception operates only under restricted circumstances. Future work should vary cognitive load and stimulus characteristics to clarify the detailed conditions under which external periodic stimulation influences human time perception.
