Transcranial Direct Current Stimulation (tDCS) is a form of noninvasive neurostimulation which has been proposed as a therapeutic procedure in numerous psychiatric conditions. TDCS therefore may be a promising therapeutic technique for reducing symptoms of psychosis, and specifically paranoia. This study will compare experiences of paranoid ideation in individuals who are high in sub-clinical paranoia across two conditions: active anodal tDCS and sham tDCS.
