The 21st year: transcription, motif list, and relation score

This study examined how the brain dynamically updates event
representations by integrating new information over multiple minutes while
segregating irrelevant input. A professional writer custom-designed a
narrative with two independent storylines, interleaving across minute-long
segments (ABAB). In the last (C) part, characters from the two storylines
meet and their shared history is revealed. Part C is designed to induce
the spontaneous recall of past events, upon the recurrence of narrative
motifs from A/B, and to shed new light on them. Our fMRI results showed
storyline-specific neural patterns, which were reinstated (i.e. became
more active) during storyline transitions. This effect increased along the
processing timescale hierarchy, peaking in the default mode network.
Similarly, the neural reinstatement of motifs was found during part C.
Furthermore, participants showing stronger motif reinstatement performed
better in integrating A/B and C events, demonstrating the role of memory
reactivation in information integration over intervening irrelevant
events. This study collected fMRI data when 25 participants listened to a
story ("The 21st year"). We implanted 28 recurrent narrative
motifs in the story, which were expected to create connections between
separate events that shared the same motifs. The participants’
understanding of the relations created by these motifs was assessed by 5
independent raters based on post-scan questionnaires. This dataset
includes the transcription of the story, the list of motifs, the fMRI
participants' responses to the relation test, and the relation
scores. (averaged across raters). Download the README.txt file for a

auditory story used in this study are also publicly available on

本研究旨在探讨大脑如何在数分钟内整合新信息、同时分离无关输入，从而动态更新事件表征。本研究由专业创作者定制设计了一则包含两条独立叙事线的故事，该故事以分钟级片段按ABAB模式交替呈现两条叙事线。在最终的C段中，两条叙事线的角色相遇并揭晓二者的共同过往。C段的设计旨在：当出现来自A/B段的叙事母题（motif）时，诱导被试自发回忆过往事件，并为这些事件提供新的解读视角。功能磁共振成像（fMRI）结果显示，存在叙事线特异性的神经活动模式，该模式在叙事线转换阶段得以复现（即活动强度升高）。该效应随加工时间层级递增，默认模式网络（default mode network）的激活达到峰值。类似地，在C段中也观察到母题的神经复现现象。进一步分析发现，母题神经复现强度更高的被试，在整合A/B段与C段事件时表现更优异，这证明了记忆复现在介入无关事件后的信息整合过程中发挥关键作用。本研究招募25名被试聆听故事《二十一岁》（The 21st year），并采集其功能磁共振成像数据。研究共植入28个重复出现的叙事母题（motif），以期在共享相同母题的独立事件间建立关联。通过扫描后问卷，由5名独立评分者对被试理解这些母题所构建的事件关联的程度进行评估。本数据集包含故事转录文本、母题列表、被试在关联测试中的作答数据，以及经评分者平均后的关联得分。如需了解数据集内容的详细说明，请下载README.txt文件。本研究使用的功能磁共振成像数据与听觉故事素材，亦可在OpenNeuro平台公开获取：https://openneuro.org/datasets/ds002245。
