内隐情绪调节的认知神经机制OA

Implicit emotion regulation refers to the process of modifying emotional responses without conscious monitoring or deliberate intention.Compared to explicit emotion regulation,implicit emotion regulation shows less dependence on the prefrontal executive control system.Building on existing dual-classification frameworks,this paper proposes a novel tripartite classification of implicit emotion regulation:automatic,task-incidental,and implicit goal-driven regulation.Automatic implicit regulation,exemplified by fear extinction,relies on the ventromedial prefrontal cortex(VMPFC)directly modulating the amygdala.Task-incidental regulation occurs during tasks such as affect labeling and emotional Stroop,where lateral prefrontal regions incidentally regulate emotions through cognitive control systems during task execution.Implicit goal-driven regulation activates automatic emotion regulation goals through priming or implicit training,which can either utilize VMPFC for automatic regulation or recruit lateral prefrontal cognitive control under certain conditions.Neuromodulation studies confirm that VMPFC is a crucial causal region for implicit emotion regulation,and enhancing its function shows promise for improving implicit emotion regulation capacity in depression and anxiety patients.The proposed tripartite framework highlights the diverse mechanisms of implicit emotion regulation,extends the dynamic understanding of emotion regulation theory,and provides promising new avenues for clinical interventions in mood disorders.
