But the illusions are not only with the eyes, we could talk about the other senses.
Lately they have become fashionable the videos of ASMR, that live of a very interesting auditory illusion, they are encumbered with a program that creates a delay in the time that takes to arrive the sound waves to your ears, deceiving it and making hear in three dimensions; because if you are able to distinguish which direction the sound is from, it is because your brain can detect to which ear the sound wave arrives before; now remember that speed of sound is an incredible 343 meters per second, the difference in arrival time between ears is ridiculous and yet manages to differentiate, our brain is amazing, but this does not end here because we are also able to discern between a sound it comes from above or below.
Although they arrive at the same time to the ears, as our brain knows then? Well, with a kind of "algorithm"; over time, your brain learned the shape of your ear and this allows you depending on how the waves bounce and distort, know if they come from below or above and once again you can play with this if you put a blindfold and you put for example plasticine the ears, "modifying" its form, it will be impossible to tell you where the sounds come from.
The sound can also be used in other ways to play with the brain, causing the emotions that really is not happening, have you experienced it? Now we prove this, that it is he who plays with us, look at the pair of figures Above, today these are two things that have names, one is called boba and the other Kike, who is who? this will have to tell me in the comments, to see if the majority matches.
And is that despite being a question without logical answer, in several experiments that have been made it has been shown that 95% of the population always gives KiKe to the first and Boba to the second, I checked it myself on twitter, and even forced the answer (question where he said that the number one was called boba), the majority was still placed on the first Kike, 76%.
The explanation of the majority of the participants; He usually claims that they choose this first option because boba sounds more rounded, while Kike more pointed, but what is happening? We are giving physical properties, dimensions to something completely dimensional and abstract for us, the sound, your brain is playing with you in a very interesting phenomenon called synesthesia.
But we can delve more about it in another post, what will the Purple know?
