Over the past years several studies emerged in the literature showing that after inducing the Rubber Hand Illusion, the illusion-limb shows a drop in temperature. At the Dijkermanlab we have attempted to replicate this effect several times of the past years, but had difficulty identifying it. With Alyanne de Haan taking the lead, our (null) findings are now bundled in a paper (No consistent cooling of the real hand in the rubber hand illusion) which is published in Acta Psychologica.
