Outcome Measures
Primary Outcomes (2)
Percentage of correct outcome predictions
Percentage of correct outcome predictions in response to predictive cues during the reversal learning task.

Study Arms (2)
Sham stimulation first, then real stimulation
EXPERIMENTALParticipants will first be delivered sham TMS stimulation. Then on a separate day, participants will be delivered real TMS stimulation.
Real stimulation first, then sham stimulation
EXPERIMENTALParticipants will first be delivered real TMS stimulation. Then on a separate day, participants will be delivered sham TMS stimulation.
Interventions
Sham TMS will be applied using the MagVenture MagPro X100 stimulator with the placebo side of the Cool-B65 A/P coil.
Real TMS will be applied using the MagVenture MagPro X100 stimulator with the active side of the Cool-B65 A/P coil.
