Schematic timeline of experimental trials for experiment 1 (A) and experiment 2 (B). In all trials, an auditory warning signal (WS) was presented, followed by a 1.5- to 2.5-s foreperiod and the auditory go signal (82 dB). On a subset of trials, a 120-dB startling acoustic stimulus (SAS) was presented 200 ms before the go signal. A: in experiment 1, transcranial magnetic stimulation (TMS) was applied on a subset of trials 80 ms following the go signal in TMS trials and 170 ms before the go signal in SAS+TMS trials. B: in experiment 2, TMS was applied 70 ms before participants’ baseline RT values for both the TMS and SAS+TMS trials. RT, reaction time.
