Although the “invisibility cloak” for now people exist only in fiction, in the real world can also come to feel invisible , concluded a study by researchers Karolinska- Stockholm Institute published today in the journal “Scientific Reports”.
To create the Illusion , the researchers knocked on more than one hundred people attending the esperimento with brush in various parts of the body and asked that the body looked With special glasses, whereas with other brush that held in the other hand mimic the same movements in the air in view of the participant.
In under a minute, most participants began transferring the feeling of brush that touched the empty space where saw moving brush and experienced the feeling of having an invisible body.
To demonstrate that the illusion really worked, neuroscientists conducted another test. They brandished a knife and plunged into the air in space representing the belly of the invisible body. “Seeing the knife, participants began to sweat,” says Arvid Guterstam, one of the authors of the experiment.
In another part of the study, the researchers showed that in situations social stressful people stay more relaxed if they are invisible .
Participants were asked in this case appear before strangers. According Guterstam, heart rate and consequent stress level it betrays was lower in those cases in which the participants had experienced shortly before the illusion of having an invisible body .
Other studies planned attempt to determine whether the sense of invisibility also influences the moral choices people make “to ensure that no future invisibility cloaks will not lead us to lose the ability to discern what is right and what is wrong, “says Henrik Ehrsson, co-author of the study
