Emotional processing deficits (EPDs) are commonly observed among individuals diagnosed with (1) psychotic disorders (2) and depression. Given that EPDs can impact overall functioning and quality of life, the need to identify effective interventions is critical. To date, our current understanding of treatments for these impairments is limited. However, there is increasing interest in investigating the efficacy of transcranial direct current stimulation (tDCS). This neuromodulation technique releases a weak electrical current through the brain. Given research suggesting promise for using tDCS to improve symptoms and cognition across psychopathology, this approach may be useful for improving EPDs and related symptoms in psychosis and depression. In the current review, we provide an overview of the literature determining the effects of tDCS for EPDs and related symptoms in these groups. Furthermore, we highlight methodological advances and pinpoint potential future directions.
