Around us, changes happen constantly. These changes are relevant, but we often ignore them, so people are said to suffer from blindness to change because we have too much confidence in our ability to detect visual changes.
To show this extreme optimism about our observation skills, we’ll see the video below. Could you identify the changes that occurred on the site?
- You found 21? Blindness to change is an issue that has begun to be investigated in recent years for its involvement in various fields and professional disciplines.
This lack of detection of changes in the visual field was first defined by Ronald Rensink in 1997, this psychologist has found differences in this phenomenon depending on whether these changes are introduced gradually or abruptly, in addition, considers this effect to be more important when changes are introduced during a cut or panoramic image , as in the case of this other video Were you able to identify the changes the first time?
Imagine we’re watching a movie. Specifically, a scene in which a salesman and a customer talk at a counter. If the seller leans over (allegedly to pick something up) and is replaced by someone else, in most cases the viewer would not notice this change. Why don’t we see such significant change?
Our brains are lazy? By nature. We are phylogenetically programmed to save as many cognitive and energy resources as possible. This is one of the explanations attributed to blindness to change.
This body is not a registrar that continuously records and processes all the details and data it presents, it tends to focus only on those most likely to be consciously modified, a selection that, in turn, is the result of experience and personal coherence. (Simons and Levin, 1998).
For example, in the above case, it is more possible that what changes in the scene is the object of the counter (placed by the seller), not one of the interlocutors, our brain assumes that it is the same person, because it saves energy.
The phenomenon is accentuated if people receive stimuli that catch their attention and keep it fixed, that would explain why, if we attend a heist and see the thief with a gun, we can barely look away from the gun. The image would drain all the attention resources we have and leave no room for more detail. We bring you another very curious video that measures this skill. You have to count how many times players in white jerseys pass the basketball.
What’s going on? Did you see the gorilla in the first place?
Illusionists or wizards often use this technique and?Enjoy? From blindness to change. They know exactly where to generate the right attention strain and how to perform the tricks at the right time Moving with this kind of invisibility layer is a real art!
As mentioned above, our daily lives are driven by change, however, instead of modestly believing that many go completely unnoticed, we are convinced that we are able to appreciate very small gradual changes, so it is often said that we are blind. Change.
Not recognizing your own limits is a limitation in itself
For example, there is an illustrative case as is common, people can follow the same path to work for years and not appreciate the small changes that occur overnight, if a wall of another color has been painted, if a traffic signal has been removed. , if an establishment has closed? Until the day when they come back, they think, how long has that happened to you?
Just as it happens in our environment, it happens in ourselves, we look in the mirror every day and we don’t appreciate the evolution and changes that occur in our face and body with age, but what if we stopped seeing each other for two likewise, when we meet a friend we don’t see in a long time , do we notice the small changes in their appearance: thinness, wrinkles, marks?However, if we saw him every day, these signs of the passage of time would not attract our attention.
Our brain is still a very little known universe, the perceptual phenomena studied in the field of neuroscience and cognitive psychology, such as blindness to change, show the complexity of this organ.
