New bodily illusion: Would you believe your hand could turn into marble?

New bodily illusion: Would you believe your hand could turn into marble? | The brain and illusions | Scoop.it
Our bodies are made of flesh and bones. We all know this, and throughout our daily lives, all our senses constantly provide converging information about this simple, factual truth. But is this always the case? A new study reports a surprising bodily illusion demonstrating how we can rapidly update our assumptions about the material qualities of our bodies based on recent multisensory perceptual experience.
Gerald Carey's insight:

Just have to include this part of the text:

"To induce an illusory perception of the material properties of the hand, a group of neuroscientists from Bielefeld University, the Max-Planck Institute for Biological Cybernetics (Germany), and the University of Milano-Bicocca (Italy) asked volunteers to sit with their hands lying on a table in front of them. They repeatedly hit the participants' right hands gently with a small hammer while replacing the natural sound of the hammer against the skin with the sound of a hammer hitting a piece of marble. Within minutes, hands started feeling stiffer, heavier, harder, less sensitive, and unnatural. Moreover, when approached by a threatening stimulus (a needle that the experimenter moved near their hands), participants showed an enhanced Galvanic skin response, thus demonstrating increased physiological arousal."


A hand that feels like granite! Unbelievable.
