Abstract Though debated, it has been argued that self-face recognition is an indicator of consciousness of self typically called self-awareness. Evidence from behavioral and neuronal studies suggests that self-recognition is associated with activation in the right prefrontal cortex (PFC). Although previous studies have examined neurological correlates of deficits in self-recognition (e.g., autism, schizophrenia), the current study attempted to examine neurological correlates of inflated self-focus. Thus, this study used transcranial magnetic stimulation to assess neurological correlates of self-recognition in different regions of the PFC and to assess whether narcissistic personality traits would be correlated with reaction time (RT) among 11 healthy participants. It was found that RT for self-face identification was positively correlated with narcissistic personality traits (p = .034). It was also found that the interaction between brain region and RT for self-faces was significant after narcissism was controlled for, demonstrating an association between narcissistic traits and self-recognition (p = .036). The results support previous research indicating the right PFC is necessary for self-face recognition. Furthermore, increases in narcissistic traits decreased self-recognition RT, and self-recognition appeared to be mediated via right PFC regions.

特殊大脑：右前额叶皮层的亚临床夸大自恋和自我面部识别

摘要 尽管存在争议，但有人认为，自我面部识别是自我意识的一个指标，通常称为自我意识。来自行为和神经元研究的证据表明，自我识别与右前额叶皮层 (PFC) 的激活有关。虽然以前的研究已经检查了自我识别缺陷（例如自闭症、精神分裂症）的神经学相关性，但目前的研究试图检查膨胀的自我关注的神经学相关性。因此，本研究使用经颅磁刺激来评估 PFC 不同区域自我识别的神经相关性，并评估 11 名健康参与者的自恋人格特征是否与反应时间 (RT) 相关。结果发现，用于自我面部识别的 RT 与自恋人格特质正相关（p = .034）。研究还发现，在自恋得到控制后，大脑区域和 RT 之间的相互作用是显着的，这表明自恋特征与自我识别之间存在关联 (p = .036)。该结果支持先前的研究，表明正确的 PFC 是自我面部识别所必需的。此外，自恋特征的增加降低了自我识别 RT，并且自我识别似乎是通过右侧 PFC 区域介导的。证明自恋特质与自我认知之间存在关联（p = .036）。该结果支持先前的研究，表明正确的 PFC 是自我面部识别所必需的。此外，自恋特征的增加降低了自我识别 RT，并且自我识别似乎是通过右侧 PFC 区域介导的。证明自恋特质与自我认知之间存在关联（p = .036）。该结果支持先前的研究，表明正确的 PFC 是自我面部识别所必需的。此外，自恋特征的增加降低了自我识别 RT，并且自我识别似乎是通过右侧 PFC 区域介导的。
