Neural basis responsible for self-control association with procrastination: Right MFC and bilateral OFC functional connectivity with left dlPFC

Abstract

Converging theory and evidence highlights procrastination as a form of self-control failure. However, the underlying neural correlates of how self-control is associated with procrastination remains unclear. As such we investigated the neural basis for self-control association with procrastination using voxel-based morphometry (VBM) and resting-state functional connectivity (FC) approaches. The VBM results showed a positive correlation between self-control and the gray matter volume of left dorsolateral prefrontal cortex (dlPFC). Then the FC of left dlPFC to lateral orbital frontal cortex (lOFC) and right dorsal medial frontal cortex (dMFC) were all negatively correlated to procrastination and showed a mediating effect. This indicates that brain functional communication involves in emotion regulation and valuation processing may account for the association between self-control and procrastination.
