AB In everyday language, social actions are usually described that involve intentionalityeither of approach or avoidance to other people. In fact, human brain has beenspecialized in the processing of social relationship. One area involved in this processingis the right Superior Temporal Sulcus (rSTS), particularly encoding intentionality int eso-called mentalizing network. In this study we propose to examine the hypothesis thatthe stimulation of the temporal region of the right STS will affectmemorization/recognition of social relationship actions of approach and avoidance, witha cognitive improvement for the approach sentences, by means of the application directcurrent (tDCS). Likewise, we examine the hypothesis that fearness, a trait of behavioralavoidance, is associated with encoding approach/avoidance of relationship actions.Sixty-eight students from the University of La Laguna participated in the study.Participants were submitted to 20 minutes of stimulation (or sham), and weresubsequently given a list of 40 sentences (half approach and half avoidance) and told totry to memorize them. Subsequently, they were told to perform a recognition taskphrase by phrase. We introduce a control condition where the participants simplyperformed the task without instruction and tDCS procedure. We found that anodicstimulation significantly improved the average performance, compared to the otherconditions, particularly in the approach sentences. The participants in the controlcondition had a significantly lower performance than in the anodic and sham conditions.In addition, we found a modulation of the effect of anodal stimulation on performanceof the task of fearfulness trait (behavioral avoidance). These results support the role ofthe right temporal cerebral region, around the Superior Temporal Sulcus, onencoding/memorizing actions of social relationships, and its modulation by theemotional personality traits.
