Psychophysical results. Probability of detecting the laser stimulus (A), and average rating of subjective pain intensity when the laser was detected (B), in the “Laser” (L) and “Laser + Touch” (L + T) conditions. Each thin line represents a single subject, whereas the thick line depicts the group average. (C) Average frequency of occurrence of the descriptors of the quality of the elicited sensation when the laser was detected, in the L and L + T conditions.
