Deficits in inhibitory learning could negatively impact extinction learning. Previous research has shown optimizing inhibitory learning has potential to improve extinction. The current study aims to improve inhibitory learning capacity through training inhibitory control to improve extinction. Our results show that training inhibitory control through stop-signal task improves extinction learning as evidenced through better reduction in UCS-expectancy, further it also resulted in reduced subjective arousal ratings during extinction. This effect was persistent and observed 24 hours later during extinction recall. Our findings imply that training inhibitory control assists in forming inhibitory associations during extinction. Further, we also observed elevated physiological arousal in training group during extinction, this explains the better recall of extinction learning during extinction recall phase. Previous research has shown better consolidation of memory under high arousal state. Improving individual capacity to form inhibitory associations enhances extinction, this finding could aid developing interventions for individuals with anxiety disorders, who show deficits in inhibitory learning. Additionally, our results also provide support to retrieval stopping hypothesis of extinction, and highlighting the domain general nature of inhibitory control involved in motoric inhibition and inhibitory processes involved in extinction.
