This study investigates the relationship between cognitive inhibition and the use of emotion regulation strategies in individuals with depression. The researchers used a negative affective priming task to assess the association between inhibition and the habitual use of rumination, reappraisal, and expressive suppression in clinically depressed, formerly depressed, and never-depressed participants. Key findings include: 1. **Cognitive Inhibition and Emotion Regulation**: Participants with depression exhibited reduced inhibition when processing negative material, which was associated with greater rumination. 2. **Strategy Use**: Across all participants, reduced inhibition of negative material was linked to less use of reappraisal and more use of expressive suppression. 3. **Formerly Depressed Participants**: In this group, less use of reappraisal, more use of rumination, and greater expressive suppression were associated with higher levels of depressive symptoms. 4. **Control Group**: The control group showed no significant correlations among the emotion regulation strategies, except for a positive correlation between suppression and rumination. The study suggests that individual differences in the use of emotion regulation strategies play a significant role in depression, with deficits in cognitive control leading to maladaptive strategies. These findings highlight the importance of understanding the cognitive processes underlying emotion regulation in the development and maintenance of depression.This study investigates the relationship between cognitive inhibition and the use of emotion regulation strategies in individuals with depression.
