Have you ever paid attention to the fact that you do not notice the obvious changes in your surrounding reality? Let's say you watch a movie in which the character wears a gray T-shirt. Here the frame changes and the character is no longer just in a gray T-shirt, but in a gray T-shirt with buttons at the neck. But you don't notice it right away, right?
Researchers at the University of California at Berkeley, along with scientists from the Massachusetts Institute of Technology, found that our brain has a section that “sticks together” our visible images of objects similar to each other, shown during the 15-second interval, in a single continuous frame, thereby creating a delay in the processing of information by our brain. Scientists from two institutes who study visual perception say that there is a so-called visual information continuity field in our brain that is responsible for this “blindness” and does not allow us to immediately see the changed objects.

A new study was conducted to determine the positive effects of such a temporary "blindness." The team of scientists says that the continuity of the visual frame helps to assimilate and fix the external image of the object, which we see constantly and in fact does not allow it to be overloaded with insignificant facts: the brain understands that objects in nature cannot change spontaneously, changing their shape and size. A cup of coffee remains a cup of coffee all the time and cannot turn, for example, into a spoon. In other words, by filtering unimportant details, our brain retains its energy and always knows what the same cup of coffee looks like.
Full details of this study were published in the latest issue of the scientific journal Nature Neuroscience. The head of the study is David Whitney, an assistant professor of psychology at the University of California at Berkeley, who was assisted by Dr. Jason Fisher from the Massachusetts Institute of Technology.
“This field of continuity allows us to smooth out our perception of objects that we see from time to time. In fact, it combines physical properties, without taking radical changes into account, in order to make objects appear similar to each other. This is truly an amazing property, because our visual system literally sacrifices the accuracy of the visible image so that this image seems continuous and complete and allows us to perceive the visible object as a whole, rather than its specific details, ”explains Whitney.
Scientists believe that this field of continuity protects our brain from "overheating". A negative factor in the absence of this field would be hypersensitivity to a variable visual scene. This means that every change in movement, lighting, shadows and other factors that we would see on the screen would begin to overload our gray matter. In this case, it would be very difficult for us to concentrate our attention on certain objects and actions.
As part of a series of experiments, researchers also found that those objects that are “glued together” by the continuity field should be located relatively close to each other. Otherwise, the effect will not work.
“Our brain remembers that objects in the real world usually do not change suddenly. And this knowledge allows us to make our visual perception more consistent and smooth, ”adds Fisher.
