Study: Not Everyone Can See the Difference Between 30 and 60 FPS
Scientists from Trinity College Dublin conducted a study focusing on the peculiarities of human vision. It was discovered that some individuals are capable of perceiving more «frames per second,» enabling them to better track fast-moving objects, whether they be tennis balls or opponents in Fortnite.
The results of the study were published in the scientific journal Plos One. The essence of the study was as follows: the scientists selected 88 people aged between 18 and 35 years and constructed a measuring device resembling VR goggles. Inside was an LED with an adjustable flicker rate. Participants were required to look into the device and indicate when the light was flickering and when it was not.
During the study, it was found that some people did not notice the flickering when the light flashed at a frequency of about 35 hertz, while others could distinguish flashes at a speed of more than 60 times per second.
According to the scientists, the «speed of perception» can vary quite significantly — the difference could be about 20 hertz. The researchers also noted that men and women perceive frequency differently, but the differences are minor.
Because we only have access to our own subjective experience, we might naively expect that everyone else perceives the world in the same way we do. This study characterises one such difference. Some people really do seem to see the world faster than others.
