London, September 28 (ANI): Scottish scientists have thrown light on what helps some magicians perform disappearing acts, revealing that illusions occur when blind spots prevent the eyes from seeing changes before them.
Experts at Edinburgh University say that spectators lose their sight for just a few milliseconds when their eyes make tiny shifts in focus, which is too short for them to notice but long enough to miss changes in visual scenes.
They carried out some experiments in which people looking at pictures often failed to detect deliberate alterations, such as objects becoming bigger or disappearing.
"We think our eyes show us the world in sharp detail all the time, but in fact this is not the case. Our studies show that our eyes do, in fact, miss a great deal. Our research gives us insight into how people see the world and ultimately how the brain processes information," the Scotsman quoted Professor John Henderson, of the School of Philosophy, Psychology and Language Sciences, as saying.
The research features in the television show Bang Goes the Theory on BBC1 at 7.30pm today. (ANI)
