It became known why people see the world with a delay of 15 seconds Researchers from the University of California at Berkeley found that the human brain processes visual information with a certain delay.

The discrepancy between his reaction and real time is about 15 seconds, according to The Conversation..

We can say that everyone lives in the past. This property helps the brain to adequately process the huge amount of visual information that comes every second..

The visible world is constantly changing due to changes in lighting, point of view and other factors.. In addition, the person himself constantly blinks and changes the position of the eyes, head and body..

The brain receives scattered and chaotic visual data, however, despite this, we see the world in the form of a stable picture.. Scientists for a long time could not understand the reason for this phenomenon..

The authors of a new study uncovered the natural mechanism associated with visual perception. So, instead of analyzing each individual visual snapshot, the brain transmits the average value of everything that we saw in the last 15 seconds..

“By combining objects to make them appear more similar to each other, our brain tricks us into perceiving a stable environment,” the scientists noted..

If the brain were updated in real time, the world would seem to people a chaotic place with constant fluctuations in light, shadow and movement.. There would be a feeling of constant hallucinations.

Living " To test their theory, the scientists recruited a team of several hundred volunteers and asked them to watch specially prepared videos..

The commercials featured close-ups of gradually aging faces.. When the participants were asked to name the age of the model at the very end of the video, almost all indicated the age of the face presented 15 seconds before the finale..

Scientists have concluded that the brain constantly sends us back in time, because " On the one hand, it helps to stabilize the picture of the world.

But on the other hand, this feature can create inconvenience when it is required to evaluate the incoming information as accurately as possible..
