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.

理论和证据的融合突显了拖延症是一种自我控制失败的形式。然而，如何将自我控制与拖延联系起来的潜在神经相关性仍不清楚。因此，我们使用基于体素的形态计量学（VBM）和静止状态功能连接（FC）方法研究了自我控制与拖延症相关的神经基础。VBM结果显示自我控制与左背外侧前额叶皮层（dlPFC）的灰质体积之间呈正相关。然后，左dlPFC到眶外侧额叶皮质（lOFC）和右背内侧额叶皮质（dMFC）的FC均与拖延呈负相关，并表现出中介作用。
