AVID: Audio-Visual Individual Differences dataset

Paper: https://doi.org/10.1093/cercor/bhad106 Four stimuli were used: (Note that the versions presented to subjects were edited to remove credits and title pages; these edited versions are available upon request out of courtesy to the filmmakers, which is why they are not in the stimuli folder). <b> Stimuli Description </b> - Iteration (https://youtu.be/c53fGdK84rc; 12:27 min:s) is a sci-fi movie that follows a female character as she goes through multiple iterations of waking up and trying to escape a facility. A male character appears toward the end to help her. - Defeat (https://youtu.be/6yN9VH_4GSQ; 7:57 min:s) follows a family of three (mother, two children) as the brother bullies his sister and she builds a time machine to go back and get revenge. - Growth (https://youtu.be/JyvFXBA3O8o; 8:27 min:s) follows a family of four (mother, father, two brothers) as the children grow up and eventually move out amid some family conflict. - Lemonade (https://youtu.be/Av07QiqmsoA; 7:27 min:s) is a Rube-Goldberg machine consisting of a series of objects that move throughout a house and ends in the pouring of a cup of lemonade. This movie was lightly edited to remove fleeting shots of human characters. <b> Additional information </b> Iteration and Defeat both contained screen cuts (continuity editing), whereas Growth and Lemonade were shot in a continuous fashion with the camera panning smoothly from one scene to the next. Runs are a bit longer than the movie stimuli themselves. We recommend dropping the first 2 TRs and the last 11 TRs for each functional run of Growth, Lemonade and Iteration and 12 TRs for Defeat (start and stop padding). Please reach out if you have any questions. <i>Growth:</i> - Total TRs: 517 - Dropped: First 2 TRs and last 11 TRs - Remaining TRs: 504 <i>Lemonade</i> - Total TRs: 461 - Dropped: First 2 TRs and last 11 TRs - Remaining TRs: 448 <i>Defeat</i> - Total TRs: 492 - Dropped: First 2 TRs and last 12 TRs - Remaining TRs: 478 <i> Iteration</i> - Total TRs: 760 - Dropped: First 2 TRs and last 11 TRs - Remaining TRs: 747 Derivatives This folder has preprocessed data - one with a shared response model applied ('nocensor_srm-recon') and one without ('_nocensor')论文：https://doi.org/10.1093/cercor/bhad106 本数据集共使用四种刺激材料： 请注意，呈现给被试的版本已被编辑以移除片尾字幕与标题页；出于对制片方的敬意，这些编辑后的版本需通过申请获取，因此未收录于刺激材料文件夹中。 **刺激材料描述** - 《迭代》（Iteration，时长12分27秒）：视频链接为https://youtu.be/c53fGdK84rc，是一部科幻短片，讲述一名女性角色多次经历苏醒并尝试逃离某设施的过程，片尾将有一名男性角色出现协助她。 - 《反击》（Defeat，时长7分57秒）：视频链接为https://youtu.be/6yN9VH_4GSQ，讲述三口之家（母亲与两名子女）的故事：兄长欺凌妹妹，妹妹随后制造一台时光机回到过去展开报复。 - 《成长》（Growth，时长8分27秒）：视频链接为https://youtu.be/JyvFXBA3O8o，讲述四口之家（母亲、父亲与两名儿子）的故事：孩子们逐渐长大，最终在伴随家庭矛盾的情况下离家独立。 - 《柠檬水》（Lemonade，时长7分27秒）：视频链接为https://youtu.be/Av07QiqmsoA，是一套鲁布·戈德堡机械（Rube-Goldberg machine）装置，由一系列在家中依次触发运动的物件组成，最终将一杯柠檬水倾倒而出。该短片经轻度编辑，移除了短暂出现的人类角色镜头。 **补充信息** 《迭代》与《反击》均采用了镜头切换（连续性剪辑，continuity editing）手法，而《成长》与《柠檬水》则采用连续拍摄方式，镜头可平滑地从一个场景过渡至下一场景。 单次功能扫描的时长略长于刺激短片本身。我们建议针对《成长》《柠檬水》与《迭代》的每一次功能扫描段，移除前2个时间重复单元（Time Repetition, TR）与后11个时间重复单元；针对《反击》则需移除前2个与后12个时间重复单元（即起止端的填充冗余）。如有任何疑问，请随时联系我们。 *《成长》*： - 总TR数：517 - 需移除：前2个TR与后11个TR - 剩余有效TR数：504 *《柠檬水》*： - 总TR数：461 - 需移除：前2个TR与后11个TR - 剩余有效TR数：448 *《反击》*： - 总TR数：492 - 需移除：前2个TR与后12个TR - 剩余有效TR数：478 *《迭代》*： - 总TR数：760 - 需移除：前2个TR与后11个TR - 剩余有效TR数：747 衍生数据 该文件夹包含预处理后的神经影像数据：一类应用了共享响应模型（shared response model），命名格式为`nocensor_srm-recon`；另一类未应用该模型，命名格式为`_nocensor`。

背景与挑战

背景概述

AVID数据集是一个专注于视听个体差异的多模态神经科学数据集，包含四个短片刺激（科幻、家庭冲突、成长故事和机械演示），用于收集功能磁共振成像（fMRI）数据。数据集提供了详细的TR（重复时间）处理信息，包括丢弃和剩余TR数，并包含预处理衍生数据，如应用共享响应模型和不应用的版本，以支持神经影像分析。
