Data from the research of Internal cost of spontaneous deception revealed by ERPs and EEG spectral perturbations

Abundant literature has studied the behavioral and neural correlates of deception, but little research has focused on the internal cost of spontaneous deception. In the present study, the event-related potential and event-related spectral perturbations techniques were used to measure the internal cost of spontaneous deception by having participants perform a sender–receiver task in which they decided whether to send deceptive messages to increase their payoff from the task. EEG data were recorded continuously with a 40-channel NuAmps DC amplifier (Compumedics Neuroscan, Inc., Charlotte, NC, USA). This dataset contains the data of deception rate, reaction time, socially appropriate rating, amplitude of RewP, grand amplitude of PCA-RewP, average power of delta, theta and beta bands.
