Study Arms:
- Transcranial magnetic stimulation (TMS), then Sham TMS. (Type: EXPERIMENTAL): Experimenters will employ a continuous theta-burst stimulation (cTBS) sequence using a figure-8 coil positioned tangentially to the scalp over the target coordinates. Experimenters have defined the target coordinates for stimulation (Montreal Neuroscience Institute coordinates -53, -53, 23) based on peak objective distancing activation in the left temporal parietal junction (TPJ) in previous fMRI studies using the same task. Thirty minutes after stimulation, experimenters will employ a sham version of the TMS intervention where subjects will receive a small electrical stimulation on the scalp via two small electrodes in conjunction with a TMS coil activation. The TMS coil will be reoriented to stimulate into the air away from the scalp, simulating traditional TMS, without inducing any current to the subject.
