Experiment 1 – Visuo-tactile stimulation followed by questionnaire. (A) Stroking of the trigger points of the participant’s stump and the corresponding parts of the mannequin’s hand – strokes were applied either in temporal synchrony or asynchrony. (B) The questionnaire consisted of 10 statements: Ownership of the mannequin’s body as a whole (Illusion statements 1–2, Control statements 7–8); Ownership of the mannequin’s hand corresponding to the participants’ intact hand (Illusion statements 3–4, Control statement 9); Ownership of the mannequin’s hand corresponding to the participants’ amputated hand (Illusion statements 5–6, Control statement 10). Participants were asked to affirm or deny each statement on a seven-point Likert scale (+3 = Strongly agree; −3 = Strongly disagree). The graph shows the mean group values with SD bars. Wilcoxon Signed Rank Tests were performed between illusion statements and control statements, as well as between the Synchronous and Asynchronous conditions – for more details see the Sections “Materials and Methods” and “Results.” *p < 0.05.
