Conditions
Interventions
Online transcranial direct current stimulation (tDCS) will be delivered by a
battery-driven electric current stimulator (Eldith DC Stimulator (CE 0118),
Ilmenau) using a pair of electrodes: (1) acti
(2) reference electrode over the central part of the
head (100 cm^2). Stimulation will be delivered during a social conformity task
(~10 min). Stimulation comprises either: (1) active tDCS (1 mA)
or (2) placebo
(sham) tDCS (0 mA).
