Experiment 2 – Visuo-tactile stimulation followed by questionnaire. (A) Stroking conditions: Condition 1 – simultaneous stroking of the trigger points of the participant’s stump and the empty space below the mannequin’s stump; Condition 2 – simultaneous stroking of the trigger points of the participant’s stump the mannequin’s stump. (B) The questionnaire consisted of six statements: Experience of the full-body illusion (Illusion statements 1–2, Control statements 3–4); Perceived location of the phantom hand (Condition 1: Illusion statement 5, Control statement 6; Condition 2: Illusion statement 6, Control statement 5). 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 Non-telescoped and Telescoped conditions – for more details see the Section “Materials and Methods” and “Results”. *p < 0.05.
