Study shows: Some people perceive the world at a higher "frame rate"

Some people perceive their surroundings with more images per second. This can have an impact on performance in fast sports and on the perception of games.
A new study from Trinity College in Dublin shows that some people perceive their surroundings at higher frequencies than others. Or, to put it another way: Some people have a higher "temporal resolution" and can therefore retrieve and process more information per second.
The results of the study suggest that people with a higher temporal resolution have an innate advantage in situations where fast reaction times are crucial. For example, in fast-paced sports or competitive gaming.
The scientific background to the study
The results of the study were not comparable.
How it was tested
Eighty-eight students from Trinity College Dublin were invited to take part in the experiment. The test subjects were all healthy and of a similar age. Their temporal resolution was tested using the "Critical Flicker Fusion" threshold, or CFF for short. The CFF threshold is the point at which an individual no longer perceives a flickering light as flickering, but as a constant light source.
An apparatus reminiscent of VR devices was developed for the experiment. The test subjects looked through glasses with a darkened viewing tube at a white LED. The flickering frequency could be adjusted up or down in 1 hertz increments using a controller.
The experiment was conducted in two steps. Firstly, the test subjects were asked to turn a constantly lit light down with the Hertz control until they could perceive a flickering. In addition, the participants had to turn the control up on a flickering light until they recognised the LED as a constant light source.
To confirm the results, in a second step the participants were presented with a series of stimuli that were either above or below the previously measured individual CFF threshold. Both steps were repeated three times for 49 participants in order to account for intrapersonal variance in the test results.
Extremely large differences between the test subjects
In addition to competitive gaming advantages, the study results could also explain differences in the perception of frame rates in games. Some players can easily play games at 30 frames per second (FPS) and swear that they don't recognise any difference to 60 FPS. Many gamers also barely notice frame rate fluctuations and jerks. Others, on the other hand, are very sensitive to low frame rates and frame rate fluctuations. <p
