Optical illusions have always attracted our attention. They are small challenges for our senses that disconcert and captivate us. Do the numbers move? Can we see faces or objects? Is there only one face or more?
All of these questions have given a lot of research to many scientists who have been interested in our mental processes and the way we process information.
The basis of this mystery focuses on how our brain works which is terribly logical. The latter wants to give meaning and balance to everything he sees and all the data that our senses send him, in this particular case, the view.
What is happening? Why this visual disorder? – wonders the brain. Unable to find an answer, the brain simply reinterprets the information.
The brain works like a statistician
The way we see our reality depends solely on our mental processes.In fact, scientists even think that if we use our brain differently, we would interpret the world differently.
Why are these images so disconcerting? Poorly defined lines, floating objects, strange perspectives … Our retina captures all these data and sends them immediately to our cerebral cortex to analyze and interpret them.
The problem is that our retina captures these images only in two dimensions. C'is limited information that focuses only on borders, colors and shapes.
How does our brain work? According to statisticians, what we see has a movement capacity. However it does not make sense. Obviously, no rational part tells us that it is impossible and that the paintings can not move, even if we have the impression.
Types of optical illusions
There are two main types of optical illusions:
1. Cognitive illusionsAs we explained earlier, our brain misinterprets the information it receives from the eyes and makes errors in the deduction from the dimension and perspective of the objects.
2. Physiological Illusion: they occur when we find ourselves in a second state. Our retina suffers from a slight disturbance in the sight of an object to which it can not adapt.
For example, we experience an "after image", when an image remains in our eyes when there is too much brightness, color, blinking.
Try to look at this picture. Gradually the rose becomes green, and if you spend a lot of time looking at the center point, the circles around it begin to disappear because the retina runs out.
All this allows us to conclude that our perception of things is not always as we think.
To perceive also means to interpret
Our world as we see it is not an exact reflection that projects through our senses to the brain. In the absolute, our brain analyzes, synthesizes, transforms and interprets.
Faced with the strange and the disorder, it brings us a balance and an answer as logically as possible. Thanks to our brains, we adapt to the world around us, and without a doubt in a more than exciting way!
