Only healthy, competent, women (18-35 years) with normal or corrected-to-normal vision will be included.
• Serious head trauma or brain surgery
• Large or ferromagnetic metal parts in the head (except for a dental wire)
• Implanted cardiac pacemaker or neurostimulator
• Pregnancy
• Skin diseases at intended electrode sites (tCS)
• Disorders of vision (i.e., deviation from *normal or corrected-to-normal vision*)
• History or current presence of any neurologic or psychiatric disease
• Any prescribed medication that can alter cortical excitability (e.g. antiepileptics, tricyclic anti-depressives or benzodiazepines) or can have an influence on the participant*s vigilance or cognitive performance within two weeks prior to participation

- Primary Outcome Measures
Name Time Method <p>Reaction time and responses, made by the participant, will be used to test<br /><br>whether anodal tDCS of the vlPFC compared with the control tDCS conditions will<br /><br>decrease the instrumental biases evoked by the emotional faces. Furthermore,<br /><br>postural sway will be used to test whether anodal tDCS of the vlPFC compared<br /><br>with the other tDCS conditions will decrease reduction of postural sway evoked<br /><br>by negative emotional faces (as a measure of an automatic emotional response). </p><br>
- Secondary Outcome Measures
Name Time Method <p>Enhanced freeze has been shown to be associated with anxiety, whereas decreased<br /><br>emotional influences on instrumental approach-avoidance biases have been found<br /><br>to be associated with instrumental aggression. To account for the effects of<br /><br>individual differences, subjective questionnaires will be administered to<br /><br>assess the individual differences in anxiety, aggression, and attentional<br /><br>control. Data of a non-social version of the task, in terms of reation time and<br /><br>responses, made by the participant, will be used to test whether offline tDCS<br /><br>of the vlPFC will decrease the instrumental biases evoked by the non-social<br /><br>emotional stimuli. </p><br>
