& #39;Demand characteristics confound the rubber hand illusion& #39; is now out in @CollabraOA! I argue that, because illusion control methods are invalid, there is currently no evidence that experience of the RHI is not attributable to suggestion effects. https://bit.ly/2UPqBn0 ">https://bit.ly/2UPqBn0&q... /1
Participants given information about the RHI induction procedure expect experience in illusion and not control conditions. Therefore, the control methods in use for 2 decades are confounded by demand characteristics and not fit for purpose.
Because RHI response is predicted by trait phenomenological control (response to direct imaginative suggestion), the illusion may be entirely a suggestion effect.
