 This study investigates the effect of upregulating prefrontal cortex activity on antisocial and aggressive behavior and risk factors for such behavior. In the double-blind, randomized controlled trial, participants will undergo anodal transcranial direct current stimulation bilaterally to the dorsolateral prefrontal cortex or a sham stimulation. During and after stimulation, they will complete survey and laboratory measures assessing antisocial and aggressive behavior and risk factors for antisocial and aggressive behavior. Heart rate and skin conductance will also be measured.
