The Effects of Film Music on Neural Activity in Higher-Order Brain Areas and Comprehension for the Film Narrative

音乐是一种强大的记忆线索，可以可靠地将我们带回过去--过去 加强我们现在和过去之间的联系纽带。现代 对情景记忆的神经科学研究可以从音乐的使用中受益，因为它 作为一种强有力的记忆线索。在这个提案中，我的目标是了解音乐是如何塑造记忆的 以及这些事件之间的联系在大脑中是如何表现的。 这项拟议的工作建立在最近的功能磁共振研究的基础上，这些研究使用了自然主义的实验 电影观看和回忆等范式对记忆理论的检验和提炼 这(之前)只在高度受控的条件下进行了测试。在这里，我们探索电影是如何 电影的形状记忆得分。在电影中，电影评分有时有反复出现的结构，其中 特定的主题曲将在整个过程中重复，可能会让人回想起信息 从之前播放过这首主题曲的活动中分离出来。基于之前的工作展示 记忆的提取会加强记忆，我们预测， 一部电影中反复出现的音乐结构会触发对之前事件的提取 看电影，这(反过来)将在以后的回忆测试中增强对这些事件的记忆。在我们的 研究中，招募了两组参与者：第一组观看电影的一个版本 它的原始形式(电影配乐完好无损)，控制组观看相同的电影 删除了整个电影配乐(同时保留了对话和环境声音)。来自两个国家的参与者 小组被要求在第二天返回，按照时间顺序回忆整部电影。通过 比较包含音乐的场景和包含音乐的先前场景之间的神经活动 (或类似的)音乐，我们希望找到神经恢复的证据。 过去在音乐组的场景；此外，我们预测更高水平的恢复在 看电影将与在音乐组中更好地回忆电影相关 与对照组比较。这项工作将提供对记忆如何工作的基础科学洞察力 在现实世界的背景下。它还将阐明音乐提示如何增强记忆力和 提高记忆力；如果观察到预测的提示效果，这些技术可以用于 未来的工作是提高记忆力受损的临床人群的表现。

Music is a powerful memory cue that can reliably transport us to our past -- in effect, strengthening the associative bond between our present and our past. Modern neuroscientific investigations of episodic memory could benefit from the use of music due to its role as a potent memory cue. In this proposal, my goal is to understand how music shapes memory for past events and how these associations between events are represented in the brain. The proposed work builds on recent functional MRI studies that have used naturalistic experimental paradigms such as movie watching and recall to test and refine theories of memory that (previously) had only been tested under highly-controlled conditions. Here we explore how film scores shape memory for movies. In movies, film scores sometimes have recurrent structure where a particular theme song will be repeated throughout, potentially bringing back to mind information from previous events in which that theme song had been played. Based on prior work showing that retrieval of a memory strengthens that memory, we predict that the presence of recurrent musical structure in a film will trigger retrieval of previous events during movie-watching, which (in turn) will boost memory for these events on a later recall test. In our study, two groups of participants are recruited: The first group watches a version of a movie in its original form (with the film score intact) and the control group watches the same film with the entire film score removed (while preserving dialogue and ambient sounds). Participants from both groups are asked to return the following day to recall the entire movie in chronological order. By comparing neural activity between scenes containing music and previous scenes containing the same (or similar) music between the two groups, we expect to find evidence of neural reinstatement of past scenes in the music group; furthermore, we predict that higher levels of reinstatement during movie-viewing will be associated with better subsequent recall of the movie in the music group relative to the control group. This work will provide basic-science insight into how memory works in real-world contexts. It will also shed light on how musical cues can strengthen memories and improve recall; if the predicted cueing effects are observed, these techniques could be used in future work to boost performance in memory-impaired clinical populations.
