The association between implicit and explicit affective inhibitory control, rumination and depressive symptoms

Area of Science:

• Cognitive psychology
• Clinical psychology
• Neuroscience

Background:

• Inhibitory control is crucial for goal-directed behavior.
• Impaired inhibition of negative information and rumination are linked to depressive symptoms.
• The precise nature of this association in non-clinical populations requires further investigation.

Purpose of the Study:

• To examine the relationship between inhibitory control over emotional and non-emotional information, rumination, and depressive symptoms.
• To investigate how depressive symptoms affect inhibitory control in different emotional contexts.
• To explore the mediating role of rumination in the association between inhibitory control and depressive symptoms.

Main Methods:

• A non-clinical sample of 119 participants with varying depressive symptom levels completed three online Go/No-Go tasks.
• Tasks involved explicit or implicit processing of emotional expressions (sad, happy, neutral) or neutral stimuli.
• Inhibitory control, rumination, and depressive symptoms were assessed.

Main Results:

• Participants with elevated depressive symptoms showed reduced inhibitory control across all task variations.
• Depressive symptoms were specifically associated with inhibitory deficits for sad and neutral expressions during implicit emotion processing.
• Trait rumination partially mediated the relationship between inhibitory control and depressive symptoms across all tasks.

Conclusions:

• Elevated depressive symptoms are associated with a general deficit in inhibitory control.
• Negative emotions, particularly during implicit processing, can interfere with inhibitory control in depression.
• Findings suggest implications for assessing and treating mood disorders by considering inhibitory control and rumination.
