当我们理解故事时，我们的注意力投入会随着时间的推移而波动。尽管叙事参与作为充满情感的注意力的理论概念，很少有实证工作的特点，认知和神经过程，包括主观参与自然主义的背景下或其后果的记忆。在这里，我们将叙事参与的波动与大脑共激活模式联系起来，并测试参与的神经特征是否能预测随后的记忆。在行为研究中，参与者不断评估他们在观看电视节目或听故事时的参与程度。自我报告的参与度在个体之间是同步的，并由叙述的情感内容驱动。在不同个体观看相同节目或听相同故事时收集的功能性MRI数据集中，参与度驱动了神经同步，因此默认模式的网络活动在叙述的更吸引人的时刻在个体之间更加同步。此外，基于随时间变化的功能性大脑连接的模型预测了参与者和独立数据集的参与状态的演变。预测参与的功能连接与持续注意力的有效神经标记重叠，并预测叙事事件的回忆。总之，我们的研究结果表征了自然主义背景下注意参与的神经特征，并阐明了叙事参与，持续注意和事件记忆之间的关系。
As we comprehend narratives, our attentional engagement fluctuates over time. Despite theoretical conceptions of narrative engagement as emotion-laden attention, little empirical work has characterized the cognitive and neural processes that comprise subjective engagement in naturalistic contexts or its consequences for memory. Here, we relate fluctuations in narrative engagement to patterns of brain coactivation and test whether neural signatures of engagement predict subsequent memory. In behavioral studies, participants continuously rated how engaged they were as they watched a television episode or listened to a story. Self-reported engagement was synchronized across individuals and driven by the emotional content of the narratives. In functional MRI datasets collected as different individuals watched the same show or listened to the same story, engagement drove neural synchrony, such that default mode network activity was more synchronized across individuals during more engaging moments of the narratives. Furthermore, models based on time-varying functional brain connectivity predicted evolving states of engagement across participants and independent datasets. The functional connections that predicted engagement overlapped with a validated neuromarker of sustained attention and predicted recall of narrative events. Together, our findings characterize the neural signatures of attentional engagement in naturalistic contexts and elucidate relationships among narrative engagement, sustained attention, and event memory.
