Decision Making in Video Games

• Conditions: Cognitive Change
• Interventions: Device: Anodal left dorsolateral prefrontal cortex tDCS stimulation; Device: Anodal right dorsolateral prefrontal cortex tDCS stimulation; Device: Sham tDCS stimulation

• Registration Number: NCT03869489
• Lead Sponsor: Tufts University

Brief Summary

The purpose of this study is to determine whether anodal transcranial direct current stimulation (tDCS) applied to the left dorsolateral prefrontal cortex induces approach motivation, and whether anodal tDCS applied to the right dorsolateral prefrontal cortex induces avoidance motivation. This study consists of three experiments: one in which an approach/avoidance video game is validated, one in which the effect of anger and fear on approach/avoidance is studied, and one in which the effect of tDCS is studied. Only the experiment in which the effect of tDCS is studied involves tDCS.
