Negative Emotion Differentiation Promotes Cognitive Reappraisal: Evidence From Electroencephalogram Oscillations and...

Area of Science:

• Neuroscience
• Cognitive Psychology
• Emotion Regulation

Background:

• Cognitive reappraisal is a key emotion regulation strategy.
• Individual differences, like negative emotion differentiation (NED), influence cognitive reappraisal.
• Neural mechanisms linking NED and cognitive reappraisal are not well understood.

Purpose of the Study:

• To investigate the influence of NED on cognitive reappraisal.
• To explore the neural basis of NED in cognitive reappraisal using electroencephalography (EEG).
• To integrate event-related potentials (ERPs), neural oscillations, and cross-frequency coupling.

Main Methods:

• Utilized electroencephalography (EEG) to record brain activity during cognitive reappraisal.
• Analyzed event-related potentials (ERPs), specifically the parietal late positive potential (LPP).
• Examined neural oscillation rhythms (theta, alpha, gamma) and their cross-frequency coupling (e.g., theta-gamma, alpha-gamma).

Main Results:

• Individuals with high NED showed reduced parietal LPP amplitudes during reappraisal, indicating enhanced ability.
• High NED individuals exhibited increased gamma synchronization and parietal alpha-gamma coupling.
• Frontal theta-gamma coupling was also elevated in high NED individuals during reappraisal.
• Machine learning confirmed multimodal neural indicators offer superior prediction of NED compared to unimodal ones.

Conclusions:

• NED significantly influences cognitive reappraisal through distinct neurophysiological mechanisms.
• Multimodal EEG analysis provides a comprehensive understanding of NED's neural basis in emotion regulation.
• Findings support the development of personalized cognitive reappraisal interventions for emotional difficulties.
