Experiment 1 – Questionnaire. The questionnaire consisted of 12 statements referring to differential aspects of the perceptual experience induced by the stroking sessions: Experience of the full-body illusion (Statements 1–4); Perceived location of the left hand (Statements 5–8); Perceived length of the left arm (Statements 9–10); Sensations of pain, numbness, burning or pins and needles, which could potentially be experienced by participants during the illusion (Statements 11-12). 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 standard error bars. Wilcoxon signed rank tests were performed between illusion statements and control statements, as well as between Condition 1 and Condition 2 – for more details see section “Methods and Results.” *p < 0.05.
