Yes, “critical flicker fusion frequency” or CFF for

Yes, I believe I understand your point.  The emotions tied up in every second can sometimesmake it feel like one has aged a million years in the time span of a few hours.  However, with boredom, it is the anticipationwhich causes the seconds to drag on.

  Also,your comment about how we would “have to wait for the rest of the world tocatch up” reminded me of pigeons.  If youwere to show a Disney cartoon to a pigeon, instead of seeing a finely drawndance sequence between Snow White and the Seven Dwarfs, the pigeon would see a seriesof images.  This is due to the wayanimated movies are produced: as a series of drawn images that are flashed ataround 24 frames per second.  This ratecan easily convince us that we are seeing a moving picture, but pigeons have a bettervisual temporal resolution.  The pigeon seeseverything slowed down.  As a small,helpless (adorable) bird, this is a good thing, as it allows them to avoidpredation.  Recently, a group of researchersconducted a study to determine if small organisms with fast metabolisms,processed and integrated visual information faster (Healy et al., 2013).

  To do this, the researchers flashed a light anddetermined at what frequency the organism perceived the light as not flashing,but as a constant stream of light (the authors refer to this as the “criticalflicker fusion frequency” or CFF for short). The researchers observed that body mass was inversely correlated to theCFF while the metabolic rate was positively correlated.  That is, small organisms with high metabolicrates had the larger CFFs.  According toTable 1 of the journal article, humans can reach a max frequency of 60 flashesper second before they just see a constant stream of light while the rockpigeon (Columba livia, a.k.a yourcommon street pigeon) maxes out at a frequency around 100 flashes per second.
