Pain dilates time perception. | LitMetric

AI Article Synopsis

  • Time feels longer during unpleasant experiences, and this study investigates how pain specifically affects our perception of time.
  • Researchers used a temporal bisection task to show that stronger pain leads to a greater distortion in time estimation.
  • The findings suggest that the link between self-awareness and pain perception may play a key role in our subjective experience of time while in discomfort.

Article Abstract

We have all experienced that time seems stretched during unpleasant situations. While there is evidence of subjective time overestimation when perceiving external unpleasant stimuli, no study has measured the dilation of time when individuals experience an unpleasant situation in their own body. Here we measured the time dilation induced by a painful homeostatic deviance using temporal bisection task. We show that being in pain leads to an expansion of subjective time whereby a stronger increase in pain perception relative to non-painful stimulation leads to a stronger time-estimate distortion. Neurophysiological studies suggest that time estimation and the perception of self might share a common neural substrate. We propose that, along with bodily arousal and attentional capture, the enhancement of self-awareness may be critical to support dilated subjective time when experiencing pain. As other homeostatic deviances, pain may induce a focus on ourselves contributing to the impression that "time stands still".
