Reality monitoring (RM) is the process of making attributional judgments about the source of a memory, in particular, to determine whether a memory is derived from internally generated or externally perceived information. This study examined the relation between self-reported RM in everyday life and temporal fluctuation of the resting-state EEG. A total of 169 undergraduates and graduates took part in the experiment, of whom data of 135 participants were analyzed. First, resting-state spontaneous EEG was recorded for five minutes in the eye-closed resting condition, and then the participants were asked to answer the 32-item Reality-Monitoring Error Experience Questionnaire (RMEEQ) in order to assess the degree to which they experience RM errors in everyday life. The results showed that the coefficient of variation of the beta peak frequency of the spontaneous oscillation at frontal area was larger for those who were more likely to report that they experience RM errors in daily life. On the other hand, the long-range temporal correlation (LRTC) of spontaneous EEG was not correlated with the RMEEQ score. Therefore, it is suggested that the unstable temporal variability of frontal beta oscillation in the resting-state EEG relates to RM measured by RMEEQ.
