The rubber hand paradigm is used to create the illusion of self-touch, by having the participant administer stimulation to a prosthetic hand while the Examiner, with an identical stimulus (index finger, paintbrush or stick), administers stimulation to the participant's hand. With synchronous stimulation, participants experience the compelling illusion that they are touching their own hand. In the current study, the robustness of this illusion was assessed using incongruent stimuli. The participant used the index finger of the right hand to administer stimulation to a prosthetic hand while the Examiner used a paintbrush to administer stimulation to the participant's left hand. The results indicate that this violation of tactile expectations does not diminish the illusion of self-touch. Participants experienced the illusion despite the use of incongruent stimuli, both when vision was precluded and when visual feedback provided clear evidence of the tactile mismatch.
橡胶手范式用于通过让参与者用假肢手施加刺激，同时检查者用相同的刺激（食指、画笔或棍棒）施加刺激来产生自我触摸的错觉。在同步刺激下，参与者强烈地体验到触摸自己手的错觉。在当前的研究中，使用不一致的刺激来评估这种错觉的稳健性。参与者使用右手的食指施加刺激到假肢手上，同时检查者使用画笔施加刺激到参与者的左手。结果表明，这种违反触觉预期的行为并不会减少自我触摸的错觉。尽管使用了不一致的刺激，当视觉受到限制或视觉反馈提供了触觉不匹配的明确证据时，参与者仍然体验到了错觉。
