Past experience of everyday life activities, which forms the basis of our knowledge about the world, greatly affects how we understand stories. Yet, little is known about how this influence is instantiated in the human brain. Here, we used functional magnetic resonance imaging to investigate how past experience facilitates functional connectivity during the comprehension of stories rich in perceptual and motor details. We found that comprehenders' past experience with the scenes and actions described in the narratives selectively modulated functional connectivity between lower- and higher-level areas within the neural systems for visual and motor processing, respectively. These intramodal interactions may play an important role in integrating personal knowledge about a narrated situation with an evolving discourse representation. This study provides empirical evidence consistent with the idea that regions related to visual and motor processing are involved in the reenactment of experience as proposed by theories of embodied cognition.
构成我们关于世界知识基础的日常生活活动的过往经历,极大地影响着我们理解故事的方式。然而,对于这种影响在人类大脑中是如何体现的,我们却知之甚少。在此,我们使用功能磁共振成像来研究过往经历如何在理解富含感知和运动细节的故事过程中促进功能连接。我们发现,理解者对叙事中所描述场景和动作的过往经历,分别选择性地调节了视觉和运动处理神经系统中低级和高级区域之间的功能连接。这些模态内的相互作用可能在将关于叙事情境的个人知识与不断发展的话语表征整合起来方面发挥重要作用。这项研究提供了与如下观点一致的实证证据:即如具身认知理论所提出的,与视觉和运动处理相关的区域参与了经历的重演。
