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到过去-- 它的作用是加强我们现在和过去之间的联系。现代 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 作为一个强有力的记忆线索。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关联在大脑中是如何表现的。 这项工作建立在最近的功能性磁共振成像研究的基础上，这些研究使用了自然的实验方法， 范例，如电影观看和回忆，以测试和完善理论的记忆 （以前）只在高度控制的条件下进行过测试。在这里，我们探讨如何电影 为电影的形状记忆打分在电影中，电影配乐有时具有循环结构， 特定的主题曲将在整个过程中重复，可能会带回到脑海中的信息 之前播放过这首主题曲的活动根据先前的工作， 记忆的恢复会加强记忆，我们预测， 电影中反复出现的音乐结构将触发对先前事件的检索， 看电影，这（反过来）会在以后的回忆测试中增强对这些事件的记忆。在我们 在一项研究中，招募了两组参与者：第一组观看一部电影的版本， 它的原始形式（与电影分数完好无损）和控制组观看相同的电影与 删除整个电影配乐（同时保留对话和环境声音）。的与会者 小组被要求在第二天返回以按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 (or相似）音乐之间的两组，我们希望找到证据的神经恢复， 过去的场景中的音乐组;此外，我们预测，更高水平的恢复期间 观看电影将与音乐组中的电影的更好的随后回忆相关联 相对于对照组。这项工作将提供基本的科学见解如何记忆工程 in real真实world世界context上下文.它还将揭示音乐线索如何加强记忆， 提高回忆;如果观察到预测的线索效应，这些技术可以用于 未来的工作，以提高记忆受损的临床人群的性能。

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.
