EEG Data from the Ultimatum Game Paradigm

The data were gathered from participants who wore a 64-channel EEG cap based on the extended 10-10 international electrode system. The participants were seated individually in a testing room and engaged in the game with a proposer through a computer interface.The EEG signals were recorded using the NeuroScan system, with AFz as the ground electrode and the NeuroScan top reference as the reference electrode.

The data were sampled at a frequency of 1000 Hz, and the impedance of all electrodes was kept below 10 kΩ to ensure signal quality. The recording process followed standard EEG procedures to minimize noise and artifact interference.
