In this study, the investigators aim to understand the role of transcranial direct current stimulation (tDCS) in modulating aberrant neurocognitive processes implicated in pediatric patients with obsessive compulsive disorder (OCD). The investigators propose two arms of the study that will investigate fear extinction learning and inhibitory control in one arm (A), and goal orientated versus habit-based behavior and inhibitory control in the other (B). All subjects will undergo three study conditions: two with active tDCS to each of two different brain targets and one under sham tDCS. The order of stimulation (sham or active tDCS) will be randomized.
