Cognitive reappraisal, an emotion regulation strategy, is linked to brain structure. Lower reappraisal ability correlates with greater gray matter volume in frontal, temporal, and parietal regions and increased negative affect.
Area of Science:
- Neuroscience
- Psychology
- Brain Imaging
Background:
- Emotion regulation is vital for psychological well-being.
- Deficits in emotion regulation are linked to psychiatric disorders.
- Cognitive reappraisal is an effective emotion regulation strategy, but its neural and psychological impacts are not fully understood.
Purpose of the Study:
- To investigate the impact of cognitive reappraisal on brain structure and psychological profiles.
- To explore individual differences in emotion regulation abilities.
Main Methods:
- Source-based morphometry (SBM) applied to MRI scans of 37 participants.
- Participants assessed for affectivity (PANAS) and empathy (IRI).
- Participants categorized into low and high reappraisers based on the Emotion Regulation Questionnaire (ERQ).
Main Results:
- Low reappraisers exhibited greater gray matter volume in a network including frontal, temporal, and parietal regions compared to high reappraisers.
- Low reappraisers reported higher levels of negative affect.
- No significant differences in empathic abilities were found between the groups.
Conclusions:
- Individual differences in cognitive reappraisal ability are associated with distinct gray matter volumes in specific brain networks.
- Cognitive reappraisal impacts brain structure and may influence experienced negative affect.
- This study provides novel insights into the neural underpinnings of emotion regulation.
