That perceived time can influence consciously observable effects like tiredness after a several minutes jog or ability to hold one’s breath is unsurprising. Park et al. show it to influence a purely physiological process of which we’re unaware and for which we have no sensation. To me at least this comes as a surprise, even more so as the effect seems to be large and consistent.
Incidentally this is one case where the choice of standard error over standard deviation is the correct one.
