本研究采用功能磁共振成像技术评估自我解释启动是否能改变成人在面部知觉过程中诱导的自我意识。在阅读了包含独立或相互依赖代词（例如，我或我们）的文章后，参与者在判断显示自己和熟悉面孔的图像的头部方向时进行扫描。当参与者看到自己的面孔而不是熟悉的面孔时，右侧额叶中部皮层的神经活动更活跃，这种差异在独立的自我解释启动后比在相互依赖的自我解释启动后更大。相对于熟悉的面孔，参与者对自己面孔的右侧额叶活动增加与更快的反应有关。我们的研究结果表明，自我意识与识别自己的脸相关的神经相关可以通过成人的自我解释启动来调节。
We used functional magnetic resonance imaging to assess whether self-construal priming can change adults' self-awareness induced during face perception. After reading essays containing independent or interdependent pronouns (e.g., I or we), participants were scanned while judging the head orientation of images showing their own and familiar faces. Neural activity in the right middle frontal cortex was greater when participants viewed their own rather than familiar faces, and this difference was larger after independent than after interdependent self-construal priming. The increased right frontal activity for participants' own faces relative to familiar faces was associated with faster responses. Our findings suggest that the neural correlates of self-awareness associated with recognition of one's own face can be modulated by self-construal priming in human adults.
