Design Emotion Dataset

## Dataset Overview | 数据集概览This dataset supports the research on "Multimodal Neurophysiological Analysis of Art-based Anxiety Intervention in University Students". It contains synchronized 64-channel EEG recordings and psychological assessments from 25 participants during a structured art healing session.本数据集支持 《多模态生理信号疗法对大学生焦虑影响的研究》。它包含了 25 名受试者在结构化艺术疗愈过程中的同步 64 通道脑电记录及心理评估数据。## Data Structure | 数据组织The data follows the BIDS (v1.8.0) international standard. Subjects are anonymized and sorted alphabetically by their name initials (e.g., sub-BJH).数据集遵循 BIDS (v1.8.0) 国际标准。受试者经匿名化处理，并按姓名缩写字母序排列（如 sub-BJH）。EEG Data: Preprocessed 64-channel signals in .edf format (Sampling rate: 200Hz, Filter: 1-40 Hz).Audio/Video Sync: Each _events.tsv file includes a video_timestamp column, ensuring synchronization error≤10 ms.Phenotype: Raw questionnaire scores (Anxiety scales) are located in the /phenotype/ folder.## Experimental Design | 实验设计The study consists of two core phases:研究包含两个核心阶段：1.Mindfulness (正念疗愈): 5-minute psychological guidance.2.Painting (手绘创作): 10-15 minutes of immersive artistic creation.## Key Validation Results | 核心验证结果The dataset's quality and predictive power have been verified using an XGBoost classifier:数据集的质量与预测效力已通过 XGBoost 分类器验证：Predictive Performance: AUC = 0.877.Core Indicators: Occipital Alpha Power (O1, O2) and Parietal Theta Power (Pz) were identified as the most significant features for predicting anxiety relief.Statistical Significance: Paired t-tests showed a significant reduction in anxiety scores (p ## Usage Instructions | 使用说明1.Refer to participants.tsv for mapping between subject IDs and psychological relief labels (1: High relief, 0: Low relief).2.Pre-processed EEG data can be loaded directly using MNE-Python or EEGLAB.3.The synchronization between EEG and behavioral video can be verified using the video_timestamp in the event files.4.请参考 participants.tsv 获取受试者 ID 与焦虑缓解标签（1: 高缓解，0: 低缓解）的对应关系。5.预处理后的脑电数据可直接使用 MNE-Python 或 EEGLAB 加载。6.脑电与行为视频的同步性可通过事件文件中的 video_timestamp 进行核验。
