Standard deviation of individual-trial RTs in the population of 10 subjects. SDs of RTs are shown during trials without TMS (left), during TMS (middle), and across all trials (right). The variance of RT performance was relatively homogeneous across subjects, apart from two subjects (7 and 10) that demonstrated a higher level of variance than the other subjects. This potential bias was taken into account in the linear mixed model by using least-squares weighting of the regression coefficients by the inverse variance of each subjects’ behavioral performance.
