Planned paired t-test comparison between sham and tDCS session for each condition indicated that the tDCS on SI significantly improved the relationship between intensity and rating for the Hand condition (Hand Sham: M = 1, DS = 0.2; Hand tDCS: M = 1.1, DS = 0.2, t (24) = –2, p=0.04), while it showed a trend for reduction in the Face condition (Face Sham: M = 1.3, DS = 0.2; Face tDCS: M = 1.2, DS = 0.2; t (24) = 1.8 p=0.07), and no appreciable change in the Color condition (Color Sham: M = 1.3, DS = 0.2; Color tDCS: M = 1.2, DS = 0.3; t (24) = 1, p=0.3).
