"We live surrounded by illusions," said Professor Peter Tse, one of the world's greatest experts in this field. In his view, these visual illusions are failure to show that everything we see is a construct of the brain. Determined to prove it, Tse projects an image that exposes to the audience for long seconds. "Has anyone noticed any change?" He asks. No one has appreciated at all, despite that it is a public "trained." A minute later, when I explained, we see that a window of the drawing has vanished from our sight, but at a slower speed so that our brain has not been able to register the change at the conscious level.
The brain fills gaps, you lose the details because all that remains on the periphery is blurred and distracted with a song, a sound or an emotion. When the magician makes us laugh, for example, low attention momentarily and leaves us more vulnerable to deception for a few seconds. It also builds a false continuity between them and other events, although the changes readily apparent.
Among other things, Luis Martínez Otero studies in his laboratory at the Institute of Neurosciences of Alicante the continuity of our perception when we perform certain tasks. "The short-term visual memory is very important to maintain the illusion of visual continuity," he said. "We are constantly moving eyes, we perceive the world in a discontinuous way, but instead seems ongoing." There are many good examples in the movies, like the famous battle scene from "Braveheart" in which Mel Gibson has a different weapon in each plane and nobody sees it, or the Chaplin film in which four or change room five times and reappear in a hat and no hat.
A related phenomenon that is the inattention blindness and is often explained by the famous video of the gorilla and passing the basketball and pollster who is swapped with another without the victim noticed a poke. When we focus our attention on a particular focus, the rest of the world disappears for our brain. Magicians use this strategy and many others for their actions, they try to look where they want and even erased from our memory of what just happened with questions that cloud our thinking and then change what we remember.
"The collaboration between magic and neuroscience works both ways," says Martinez-Conde. "Mages are also very interested in how perception works and how to improve their tricks." Scientists are not just using the tricks to understand how the perception, but to test cognitive skills. Peter Johansson, Lars Hall, for example, used a little sleight of hand to change their choice of subjects between two options. Participants chose between two photographs and explained why they had chosen one of them without realizing that the researcher had given them the option discarded. His work has served to deepen a phenomenon known as blind to the election and demonstrate that our opinions are much more malleable than we think.
Anthony Barnhart is the only speaker who has his feet on both sides of the field. "I started as a magician", he explains, "before being psychologist." "As you develop your interest in magic and learn how to fool people," he confesses, "I fail to realize how our perceptions." Their findings are quite disturbing because they indicate that our brains see over and over again the same enthusiasm or be fixed in the same foci of very smart that we create. "In fact," reveals someone off-camera, "some believe that the best age to deceive is believed to be most ready."
For four nights, magicians and neuroscientists have traded secrets to improve our knowledge of both disciplines. On one side of the table, the great James Randi takes a flower from the hair of some guests. In the other, Eric Mead remembers the night that a tiger escaped from a cage in Las Vegas and left claw marks on the hood of a car and Max Maven talks about the guy who did believe it had dice in the fist sounding fractured bones of his knuckles.
"What did I just see, what happened?" This perfectly sums up the feeling with which we were after a magic trick. Something that is seemingly impossible has become possible for a moment, the child within us wants to believe is true, play to slide down the slope of astonishment. The answer is a few inches away in these neural pathways evolved to perceive shapes, colors and movements in a certain way. Scientists are beginning to understand how to create illusions and put your head between these mysterious scenes that place where our perceptions become a bunch of pigeons and rabbit popped out of a hat.
