The association between the error-related negativity and self-control is moderated by impulsivity and compulsivity

Area of Science:

• Cognitive Neuroscience
• Behavioral Psychology

Background:

• Impaired self-control is linked to performance monitoring deficits.
• Altered error-related negativity (ERN) is seen in impulsive/compulsive disorders.
• The link between monitoring signals and behavior needs clarification.

Purpose of the Study:

• To investigate how impulsivity and compulsivity influence daily self-control.
• To examine the moderating role of these traits on the ERN-self-control relationship.
• To understand the translation of performance monitoring into adaptive behavior.

Main Methods:

• Combined electroencephalography (EEG) with ecological momentary assessment (EMA).
• Assessed 221 participants for trait impulsivity, compulsivity, and daily self-control.
• Analyzed the association between ERN amplitude and daily self-control, moderated by traits.

Main Results:

• High compulsivity correlated with increased desire enactment and self-control failures.
• ERN amplitude predicted better self-control only when impulsivity and compulsivity were low.
• The performance monitoring-self-control link is contingent on trait levels.

Conclusions:

• Trait impulsivity and compulsivity significantly moderate the relationship between performance monitoring and daily self-control.
• Cognitive and neural models of self-control should incorporate trait interactions.
• Findings suggest a nuanced understanding of how monitoring translates to adaptive behavior.
