Hand Temperature Is Not Consistent With Illusory Strength During the Rubber Hand Illusion

Contrary to previous claims, skin temperature is not a biomarker for ownership. We induced the Rubber Hand Illusion (RHI), the gold standard experiment to study the sense of ownership, while monitoring the participants skin temperature with a precise thermal camera. We found that temperature change does not correlate with the ownership score in the RHI paradigm and thus suggest caution in drawing strong inferences of ownership based on the skin temperature.
