EEG data of 239 participants during passive viewing of IAPS images in clearly distinct valence categories (positive, neutral, negative) with MatLab scripts

The dataset contains EEG data (raw and preprocessed) of 239 participants that passively viewed 150 IAPS images in three clearly distinct valence categories (positive, neutral, and negative) based on normative valence ratings. Participants provided subjective ratings for each image. MatLab analysis scripts are included.

本数据集包含239名被试的脑电（EEG，Electroencephalogram）数据，涵盖原始数据与预处理后数据。全体被试被动观看了150张国际情感图片系统（IAPS，International Affective Picture System）图片，上述图片依据标准化效价评分被划分为三类界限分明的效价类别：正性、中性与负性。所有被试均为每张观看图片提供了主观评分。本数据集附带MATLAB分析脚本。
