Fig. 1

Box-plot with medians, quartiles and the min and max as whiskers shows value of SCRs_Amp with respect to the stimulus intensity. *p<0.05 and **p<0.005.

Fig. 2

Box-plot with medians, quartiles and the min and max as whiskers shows value of SPRs_Amp with respect to the stimulus intensity.

Fig. 3

Box-plot with medians, quartiles and the min and max as whiskers shows value of SSRs_Amp with respect to the stimulus intensity. *p<0.05.

Fig. 4

Shows relation between average values of amplitudes of SCRs, SPRs and SSRs on one side, and the stimulus intensity on other side.

Fig. 5

A typical EDA recording from a participant, demonstrating changes in EDA responses with respect to painful stimuli.

Fig. 6

Box-plot with medians, quartiles and the min and max as whiskers, showing the SPRET percentage for all participants with respect to the stimulus intensity.*p<0.05 and **p<0.005.

Fig. 7

SPRET percentage for each category.

Fig. 8

SCR_Trise to the different stimulus intensity presented as box-plots with medians, quartiles and the min and max as whiskers. **p<0.005.
