Previous research has demonstrated that the Action-Observation Network (AON) is involved in both emotional-embodiment (empathy) and action-embodiment mechanisms. In the current study, we hypothesized that interfering with the AON will impair action recognition and that this impairment will be modulated by empathy levels. Fifty-two participants conducted a semantic decision task of hand gesture recognition, while we interfered with the AON by applying active (n = 26) or sham (n = 26) transcranial Direct Current Stimulation (tDCS) to the hand area of the primary motor cortex. We found that interfering with the AON impaired the performance of participants with high empathy levels and enhanced the performance of participants with low empathy. This finding suggests that the embodiment module may be flexible, and that it can be enhanced in individuals with low empathy by simple manipulation of motor activation.

移情和运动皮层刺激对手势理解的交互作用。

先前的研究表明，行动观察网络（AON）参与了情感体现（同情）和行动体现机制。在当前的研究中，我们假设干扰AON会损害动作识别，并且这种损害将由同理心水平进行调节。52名参与者进行了手势识别的语义决策任务，而我们通过对主动电机的手部区域施加主动（n = 26）或假（n = 26）经颅直流电刺激（tDCS）来干扰AON。皮层。我们发现干扰AON会损害具有较高共情水平的参与者的表现，并会增强具有较低共情水平的参与者的表现。该发现表明实施例模块可以是灵活的，
