Fig. 3: The effect of TMS on accuracy and reaction time data.

Box plot summary of accuracy (a) and reaction time (b) data depicting the minimum and maximum values, the lower and upper quartiles and the median scores. Individual data points are indicated by open circles. Lighter-coloured bars depict congruent trials, and darker-coloured bars depict incongruent trials. Accuracy data (a) showed a main effect of congruency (no interaction). RT data (b, correct trials only) revealed that participants were faster in congruent trials than incongruent trials under the Control TMS condition but showed no evidence of a congruency effect under Active TMS (significant interaction). **P < 0.01. N = 20 participants.
