Study Arms:
- Real - sham anodal tDCS (Type: EXPERIMENTAL): Session 1: 20 min of 1 mA anodal tDCS applied via 5x7 cm rubber electrodes over the DLPFC (current density: 0.028 mA/cm2). Additional ramp-up and ramp-down phase at beginning and end of stimulation lasting for 15 s. Electrodes remain attached to the participant's head for the duration of the encoding phase.~Session 2: 30 s of 1 mA anodal tDCS applied via 5x7 cm rubber electrodes over the DLPFC (current density: 0.028 mA/cm2). Additional ramp-up and ramp-down phase at beginning and end of stimulation lasting for 15 s. Electrodes remain attached to the participant's head for the duration of the encoding phase.
