Study Links Childhood Trauma to Procrastination in 1,189 Students via Brain Network Changes

Summary
Brain scans and surveys from 1,189 Chinese undergraduates tied higher childhood trauma scores to more procrastination, with the strongest new evidence coming from resting-state neural connectivity patterns.
Trait anxiety and self-control explained much of that link: trauma was associated with higher baseline anxiety and weaker self-control, which in turn predicted chronic delay.
A model trained on 760 students and tested on 429 others predicted trauma scores from brain activity alone, highlighting weaker prefrontal control-network connectivity and stronger emotion-related visual-cerebellar links.
Those patterns fit the triple-network model of procrastination, in which imbalances across self-control, salience and future-planning systems make stressful tasks feel more threatening and easier to avoid.
The NeuroImage study was cross-sectional and relied on self-reported trauma histories, so it cannot prove causation and may not generalize beyond healthy college students.
