Area of Science:

• Neuroscience
• Cognitive Psychology

Background:

• Need for Cognitive Closure (NCC) describes the desire for certainty and clear answers.
• Previous research on NCC primarily examined task-related brain activity.

Purpose of the Study:

• Investigate resting-state (RS) electroencephalographic (EEG) intra-network dynamics linked to NCC.
• Apply the Triple Network (TN) model to understand resting-state NCC processes.

Main Methods:

• Recruited 52 young adults for resting-state EEG recordings.
• Utilized exact Low-Resolution Electromagnetic Tomography (eLORETA) for functional connectivity analysis.

Main Results:

• Higher NCC correlated with decreased alpha EEG connectivity in the Central Executive Network (CEN).
• Higher NCC correlated with increased delta EEG connectivity in the Default Mode Network (DMN).
• No significant NCC correlation found with Salience Network (SN) connectivity.

Conclusions:

• Resting-state brain communication patterns in CEN and DMN are associated with NCC levels.
• These neurophysiological patterns may reflect cognitive traits like reduced flexibility and preference for rigid responses.
