Experimental setup. Subjects practiced a sequential finger‐tapping task (a) two sessions were administered 1 week apart in a counterbalanced manner. Both sessions began with a single baseline test. Next, one session included an offline inhibitory 1 Hz rTMS of right lPFC, while the other included a control stimulation (see main text). In each of the sessions, subjects then performed 12 trials of training, lasting 30 s each, separated by 30 s breaks. (b) The task required subjects to repeatedly tap a 5‐element sequence of finger movements with their left nondominant hand as quickly and accurately as possible. Monetary reward was stochastically administered, as a strategy to facilitate learning gains (see Section 2).
