Dataset of public stereotypes on recycled water use through event-related potential(ERP)

This event-related potential experiment on public acceptance of recycled water use was conducted in the Laboratory of Neuromanagement in Engineering of Xi’an University of Architecture and Technology. 37 participants were recruited to participate in the EEG experiment, including 18 males and 19 females. A preprocess of the EEG data was conducted, and 5 invalid samples were eliminated due to the limited number of or invalid marks they presented. Finally, 32 valid samples were kept for analysis. Curry 8 was used to extract the analysis time windows in the EEG and to superimpose and average the N400 waveforms of different experimental participants induced by different stimuli, and to derive the average N400 brain potential waveform amplitude. In this dataset, the more negative the amplitude of N400, the stronger the negative stereotype on recycled water reuse is presented.

本项针对公众对再生水利用接受度的事件相关电位（event-related potential, ERP）实验，于西安建筑科技大学工程神经管理实验室完成。实验共招募37名被试参与脑电图（electroencephalogram, EEG）测试，其中男性18名、女性19名。研究团队首先对脑电图数据开展预处理，剔除5份因标记数量不足或标记无效的无效样本，最终保留32份有效样本用于后续分析。本研究采用Curry 8软件提取脑电图分析时窗，对不同刺激诱发的各实验被试的N400波形进行叠加平均，并计算得到平均N400脑电位波形幅值。在本数据集中，N400幅值越负，表明被试对再生水回用的负面刻板印象越强。
