颞顶联合区（TPJ）是“社会脑”中的关键节点[1]。几项研究表明，TPJ控制着自我或另一个个体在各种低层次（代理歧视[2]，视觉观点采择[3]，模仿控制[4]）和高层次（心智化，共情[4-6]）社会认知过程中的表征。我们探讨了依赖于自我和其他表征的在线控制的社会认知能力是否可以通过TPJ的经颅直流电刺激（tDCS）进行调制。参与者在完成三项社会认知任务之前接受兴奋性（阳极）、抑制性（阴极）或假刺激。阳极刺激提高了在线控制的自我-他人的陈述引起的模仿和观点采择任务，而不影响归因的心理状态在一个自我参照的任务，没有这样的要求。我们的研究结果证明了tDCS在改善社会认知方面的功效，并强调了tDCS作为帮助临床人群进行自我-他人处理的工具的潜力。
The temporoparietal junction (TPJ) is a key node within the "social brain" [1]. Several studies suggest that the TPJ controls representations of the self or another individual across a variety of low-level (agency discrimination [2], visual perspective taking [3], control of imitation [4]) and high-level (mentalizing, empathy [4-6]) sociocognitive processes. We explored whether sociocognitive abilities relying on on-line control of self and other representations could be modulated with transcranial direct current stimulation (tDCS) of TPJ. Participants received excitatory (anodal), inhibitory (cathodal), or sham stimulation before completing three sociocognitive tasks. Anodal stimulation improved the on-line control of self-other representations elicited by the imitation and perspective-taking tasks while not affecting attribution of mental states during a self-referential task devoid of such a requirement. Our findings demonstrate the efficacy of tDCS to improve social cognition and highlight the potential for tDCS to be used as a tool to aid self-other processing in clinical populations.
