Supplementary Fig. 1. Behavioral measures for ‘self’, ‘other’, and ‘computer’. (a) Mean trial-by-trial subjective intensity of pain rated on a Numerical Rating Scale (NRS) ranging from 0 (= not painful at all) to 100 (= strongest imaginable pain). (b) Mean level of anxiety rated on a NRS ranging from 0 (= not anxious at all) to 10 (= extremely anxious). * p< 0.05, ** p<0.01. ‘Self’: noxious stimulation could b stopped by the participant, ‘other’: noxious stimulation was thought to be controlled by another person, ‘computer’: noxious stimulation was thought to be controlled by a computer.

Supplementary Fig. 2. Correlation between general belief to have control and activation of right alPFC for both external conditions. In both externally controlled conditions (‘other’ and ‘computer’) the activation of the right alPFC (x,y,z: 36,48,15) was negatively correlated with the general belief to have control over one’s own life. Note, that the correlation coefficient for both conditions was almost identical.
