The standard RHI questionnaire adapted to fit an experiment with tapping stimulation on a rubber hand.
| During the experiment … | |
|---|---|
| Q1 | … I felt as if the prosthetic hand was my hand |
| Q2 | … it seemed as if the sensation I felt was caused by the tapper tapping the prosthetic hand |
| Q3 | … it seemed like I was looking directly at my own hand, rather than at a prosthetic hand |
| Q4 | … it seemed like the prosthetic hand was part of my body |
| Q5 | … it felt as if my right hand was drifting towards the prosthetic hand |
| Q6 | … it seemed as if the sensation I felt came from somewhere between my residual limb and the prosthetic hand |
| Q7 | … it appeared as if the prosthetic hand was drifting towards my right hand |
| Q8 | … the prosthetic hand started to change shape, color, and appearance so that it (visually) started to resemble my right hand |
The first four questions are adapted from Longo et al.64 and are used to establish if the ownership illusion was successful. The other four questions are control statements.
