The Rubber Hand Illusion – Horizon: Is Seeing Believing? – BBC Two

Hi, I’m larry. Hi [very] nice to meet you [ad] we’re gonna do a little demonstration here called the rubber hand illusion It’s gonna be a little disillusioned. You’re gonna [figure] out [fun], but it reveals The most important you. I don’t your other hand out [inside]. Thank you [alright] Good and can you put this hand down right over here and just curl it up like the rubber hands curled up a little bit All right now what I’m going to do is try to position the rubber hand, so it looks like it’s your own Okay, could you imagine that being your own hand kinda what we’re going to do is we’re going to stroke your fingers simultaneously the rubber finger and your real finger and Hopefully this will convince you that the rubber hand is your own that your brain will actually adopt this hand In the illusion simply watching the rubber hand being stroked at the same time as the is Enough to trick the brain into adopting it as it’s in on it. We like weird and [slowly], but surely you should feel at the hand you’re looking at is actually part of your body feels like you’re touching My hand with that one right so it feels like this is your hand that I’m touching right Okay, yeah, I try that at home with your kids Yeah, the rubber hand illusion is a wonderful example of how multi sensory perception can influence How we perceive our own body? I mean that’s how deep multi sensory perception runs when you hold your hand out It’s generally [thought] that you know it’s there because of the information you’re getting from your muscles and your tendons and that sort of thing But what the the rubber hand illusion does is show how that can be overwritten by visual information? Okay, remember comes your fun surprise. She’s the powerful connection between what we see and what we feel But it reveals even more than [the] way our senses are connected It hints that a fundamental change in the brain is taking place. Oh That’s strange. Yeah, that’s creepy. So what might be going on in the rubber hand illusion Is that the brain is actually changing to accommodate the new Rubber hand? Going through some sort of you know structural change that we call neuroplasticity Neuroplasticity is an exciting new idea that suggests the brain can change in response to experience And this is what’s taking place in the rubber hand? The Brain may be temporarily rewiring itself to adopt a plastic head very as its own Really feeling like it’s your hand now, huh? That a little weird yeah, we like weird in Perceptual psychology Yeah With that scary [guy] [we] like that
