The aim of this observational study is to investigate human time perception ability for different time intervals (540 ms, 1080 ms, 1620 ms, 2160 ms, 5 s, 10 s, 20 s, 50 s) under conditions of varying altitudes (500 m, 1000 m, 1500 m, 2000 m, 2500 m, 3000 m). Specifically, a hypobaric chamber will be used to simulate the aforementioned altitudes, and temporal reproduction tasks with different standard durations will be conducted at each altitude. The time difference between the actual perceived duration and the target duration will be calculated to assess the level of time perception ability-with a smaller difference indicating stronger time perception ability. At each altitude, participants' heart rate (HR) and oxygen saturation (SpO₂) will also be monitored to explore the correlation between physiological status and time perception ability under different altitude conditions.
