Inhibitory learning forms an essential component of extinction. Deficits in inhibitory learning could negatively impact extinction learning (Craske et al., 2008). The current study aims to improve inhibitory learning capacity through training inhibitory control to improve extinction. Fifty-one participants completed a 3-day fear conditioning paradigm (Day1: Acquisition; Day2: Extinction; Day 3: Extinction recall). Participants were divided in two groups inhibitory control training and extinction (IC-SE) and standard extinction group (SE), participants performed stop-signal task before extinction in IC-SE group. An independent sample t-test on CS+ expectancy rating during extinction t(49) = -2.211, p = .032, d = -.620, and re-extinction t(49) = -2.567, p = .011, d= -.746 revealed a significant group difference between IC-SE and SE group, with lower CS+ expectancy ratings in IC-SE than SE group. Further, we also found a significant group difference in subjective arousal of CS+ during extinction t(49) = -2.760, p = .008, d = -.774 and re-extinction t(49) = -2.548, p = .014, d= -.715, with lower CS+ arousal ratings in IC-SE than SE group. Our findings imply training inhibitory control assists in forming inhibitory associations during extinction, resulting in reduced UCS-expectancy in IC-SE group. Further, we observed elevated physiological arousal in IC-SE group during extinction. Previous research has shown better consolidation of memory under high arousal state, this explains the better recall of extinction learning during extinction recall phase. Improving inhibitory control enhances extinction, this finding can aid development of interventions for individuals with anxiety disorders, who show deficits in inhibitory learning.
