Questionnaire results.

		Median ± IQR
Question	Label	Synchronous	Asynchronous	P
Q1 It seemed as if I were feeling the touch of the ball in the location where I saw the virtual body touched.	Referred touch	5 ± 1	2 ± 2	<0.00005
Q2 It seemed as though the touch I felt was caused by the ball touching the virtual body.	Caused by ball	4 ± 1	4 ± 2	0.030
Q3 It felt as if the virtual body was my body.	My body	3 ± 1	3 ± 0	0.422
Q4 It felt as if my (real) body was drifting toward the front (toward the virtual body).	Drifting forward	2 ± 2	2 ± 3	0.897
Q5 It seemed as if I might have had more than one body.	More than one body	2 ± 2	2 ± 2	0.880
Q6 It seemed as if the touch I was feeling came from somewhere between my own body and the virtual body.	Touch between	2 ± 2	3 ± 3	0.366
Q7 It appeared (visually) as if the virtual body was drifting backwards (toward the real body).	Avatar drifting backwards	2 ± 2	1 ± 1	0.180
Q8 During the experiment the body I saw was that of another person.	Another person	3 ± 3	3 ± 2	0.525
Q9 When the fan descended over the head of the virtual body in front, it felt as if it could chop my head.	Head chop	3 ± 3	3 ± 2	0.814

The question scores are on a 1–5 Likert scale with 1 indicating the most disagreement and 5 the most agreement with the statement. The median and interquartile range is given for each question by Synchronous and Asynchronous. The P-value is for test of equality of the two groups using two-sided Wilcoxon rank-sum test (n = 15 in each group).
