Transcranial direct current stimulation (tDCS) has become an increasingly popular noninvasive neuromodulatory tool in the fields of cognitive enhancement. It is an inexpensive, painless, and safe brain stimulation technique that has already proven to be effective in promoting cognitive and sensory-perceptual functioning in healthy individuals. Importantly, recent findings have provided evidence showing that tDCS may be an effective and promising tool to enhance social cognition as well. In this chapter, we review the state of art of this growing field of research to gain a better understanding of the potential of tDCS to enhance social cognitive functioning and of the factors that may affect the likelihood of tDCS effects. Although more research is needed to fully understand the effects tDCS exert on social cognition at long term, we conclude that tDCS is a promising tool for enhancing the ability to handle self-other representations.
