Scientists discover speed of visual perception ranges widely in humans
https://medicalxpress.com/news/2024-04-scientists-visual-perception-ranges-widely.html

Using a blink-and-you’ll-miss-it experiment, researchers from Trinity College Dublin have discovered that individuals differ widely in the rate at which they perceive visual signals. Some people perceive a rapidly changing visual cue at frequencies that others cannot, which means some access more visual information per timeframe than others.

“This study characterizes one such difference—in the ‘frame rate’ of our visual systems. Some people really do seem to see the world faster than others.”

…

I’ve always wondered if this perception would be analogous to time being slowed down for some people compared to others.

To quantify this, the scientists used the “critical flicker fusion threshold,” a measure for the maximum frequency at which an individual can perceive a flickering light source.

If the light source flickers above a person’s threshold, they will not be able to see that it is flickering, and instead see the light as steady. Some participants in the experiment indicated they saw the light as completely still when it was in fact flashing about 35 times per second, while others were still able to perceive the flashing at rates of over 60 times per second.

So temporal resolution is different so some people do see more of the world while others see slightly less of the world, over ones lifetime that figure could be significant.

So “scientists have found” what sports coaches and selectors have already found.

Used to be called “hand eye coordination”

Well it’s been validated by science.

It has implications for on line gamers.

Certainly it has implications for sport.

Defence too. Fighter jet pilots.

I’m terrible at it.

All you could want to know about Critical Fusion Frequency. I learnt about it at a lecture during my optometry training in 1980. The link below is to a recent overview.

probably a modern thing, to generalize latency as all or always bad, could even be an indication of a thought disorder in another world

i’m going to go back to experimenting with the long blink shortly, return to my sleep
