Abstract
The perception of time is a fundamental aspect of human cognition, influenced by various physiological and psychological factors. One potential modulator of subjective time perception is heart activity, yet its precise role remains insufficiently explored. This study investigated the relationship between cardiac activity and the perception of time duration, particularly in isolated and high-stress environments. The idea for this research originated from observations that autonomic nervous system activity, including heart rate variability, could influence time estimation and temporal processing. The study was conducted during an analog space mission, where participants (analog astronauts) were subjected to controlled experimental conditions in an environment designed to mimic the isolation and psychological demands of space. Additional research was conducted during an expedition to the Himalayas to further investigate the effects of changing conditions and time of day on time perception. Each day of the mission, heart activity was recorded using advanced devices to monitor heart rate and variability. Concurrently, participants performed specific time estimation tasks, including assessing the duration of auditory and visual stimuli. The auditory task required participants to estimate the length of a presented sound, while the visual task involved judging the duration of a displayed visual stimulus. These tasks were designed to analyse potential variations in subjective time perception in relation to cardiac dynamics. The results indicated a correlation between heart rate fluctuations and deviations in time perception. Variations in heart rate variability modulated these effects, suggesting an interaction between autonomic regulation and cognitive time processing. These findings contributed to a better understanding of the physiological basis of time perception and may have implications for future space missions and extreme environment training. A deeper comprehension of how cardiac activity influences temporal perception could aid in developing countermeasures for cognitive distortions in astronauts, ultimately enhancing their decision-making and psychological well-being during long-duration missions.
