The self integrates information across time, but how this psychological temporal integration relates to neuronal temporal integration is unclear. In a modified self-matching task with temporal delays, participants showed a self-prioritization effect—greater accuracy for self-related stimuli—across all delay conditions, indicating stronger temporal integration of self-related information. Resting-state EEG measures of scale-free dynamics (power law exponent and autocorrelation window) indexed neuronal temporal integration. Higher neuronal integration was associated with a stronger increase in the self-prioritization effect over longer delays. Temporal integration on the neuronal level appears to serve as a template for psychological-level self-integration, suggesting it acts as a common currency linking neuronal and psychological aspects of self.
