Overview of experiments.
Figure 1.
This figure displays the main experimental set-up (A), the four artificial bodies (B), and the image seen by participants during visuo-tactile stimulation (C), the Barbie doll experiment (D), object size estimation (E), and distance estimation (F).

Results of Experiments 1–4: Illusory ownership of tiny and huge artificial bodies.
Average scores on illusion statements and control statements (see Table S1) after synchronous and asynchronous touching of small body (A) and large body (B), and average threat-evoked SCR after a period of synchronous and asynchronous touching of the small body (C) and the large body (D). * p<0.05, *** p<0.001. Error bars indicate SEM.
Figure 3.
Results of Experiment 5: Illusory ownership of the body of a Barbie doll.
Average scores for illusion statements, control statements and statements regarding the size of seen objects (see Table S1). ** p<0.01, *** p<0.001. Error bars indicate SEM.
Figure 4.
Results of Experiments 6–8: Own body size effect on size perception.
The body size effect on verbal size estimation (A) and hand aperture (B) as a percentage deviation from the average estimation of all trials and the effect of the ownership illusion on hand aperture as a percentage deviation from corresponding asynchronous condition (C). * p<0.05, ** p<0.01, *** p<0.001. Error bars indicate SEM.

Results of Experiments 9 and 10: Own body size effect on distance perception.
The body-size effect on verbal distance estimation as a percentage deviation from average estimations (A) and as percentage deviation from the corresponding asynchronous condition (B). The body-size effect on walking distance as a percentage deviation from average estimations (C) and as a percentage deviation from the corresponding asynchronous condition (D). * p<0.05, ** p<0.01, *** p<0.001. Error bars indicate SEM.
