Results from Experiment 1.

<p>Left: Proprioceptive drift did not differ significantly between the synchronous and the asynchronous group, mean and s.e.m. N = 20. Right: The questionnaire results confirm that the procedure of interrupting stimulation every 10 s brings about the ownership illusion. Boldface questionnaire items indicate the occurrence of the ownership illusion. In the synchronous condition, questionnaire items Q1 and Q3 are rated significantly positive (p = 0.002; after Bonferroni correction for multiple measures: p = 0.018). Questionnaire item Q2 is nearly significantly positive (one negative reply, p = 0.022; after Bonferroni correction for multiple measures: p = 0.195). Error bars: 25 percentile−75 percentile; N = 20.
