In the other 1800s , a scientist called Charles Wheatstone knew that the slim difference of opinion in the image check by the unexpended eye and the good oculus was what give people deepness sensing . He wondered , though , what exactly would pass off if he point each centre radically different things ?
He suppose that the mind would intermingle those thing together , and so he set up a kind of cuneus that would show one oculus a face , and the other a house . The people should see a house with a human face , he imagine . ( And if they did , would n’t it be awesome ? Oh well . ) rather , when he put the machine up to their center , they saw a aspect , then a sign of the zodiac , then a face , and then a house . Instead of shading , the images alternated , and the brain paid aid first to one heart ’s input and then the other . He call this phenomenon “ binocular rivalry . ”
This canonic binocular contention set - up has been the base for a lot of experiment in sensing since then . One of those experiment discovered a phenomenon call “ continuous flash suppression , ” possibly because “ functionally dim someone in one heart ” did n’t have a nice mob to it . The brain does n’t pay tending to everything at once . You , right now , are focusing on this page , and have not noticed the rest of your desk . If your computed axial tomography were to jump up into your sight , you ’d see it , because it move and caught your attention . If a person were to show one centre a uninterrupted flow of brightly shoot rectangles , or other apace changing images , while the other heart is shown a static , or nearly - motionless ikon , the static image is suppressed . It ’s not just a matter of focal point — one optic is essentially blinded for a while . And this method has been register to subdue the static range of a function for longer period of time than nearly any other technique . Just like the dinosaur in Jurassic Park , we can sometimes only see what movement .
So if you need to freak someone out , or just have a little fun determination out what it ’s like to be a water flea for a while , try suppressing an eye .
