Readers structure narrative text into a series of events in order to understand and remember the text. In this study, subjects read brief narratives describing everyday activities while brain activity was recorded with functional magnetic resonance imaging. Subjects later read the stories again to divide them into large and small events. During the initial reading, points later identified as boundaries between events were associated with transient increases in activity in a number of brain regions whose activity was mediated by changes in the narrated situation, such as changes in characters' goals. These results indicate that the segmentation of narrated activities into events is a spontaneous part of reading, and that this process of segmentation is likely dependent on neural responses to changes in the narrated situation.
读者将叙事文本构建成一系列事件,以便理解和记住文本。在本研究中,受试者阅读描述日常活动的简短叙事,同时用功能磁共振成像记录大脑活动。受试者随后再次阅读这些故事,将其分为大事件和小事件。在初次阅读期间,后来被确定为事件边界的点与多个脑区活动的短暂增加相关,这些脑区的活动由叙述情境的变化介导,例如人物目标的变化。这些结果表明,将叙述的活动分割成事件是阅读的一个自发部分,并且这种分割过程可能依赖于对叙述情境变化的神经反应。
