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.
