Cognitive Process In High Neuroticism: Incompatible Flexibility In Frontal Brain Region

Objective: This study examines the difference of interference effect in high and low neuroticism.
Material and Methods: Low and high groups of neuroticism performed the congruent and
incongruent Stroop Colour Word task in the Event Related Potential session. The ERP P300
was extracted and analysed.
Results: High neuroticism exhibited larger P300 amplitude than low neuroticism in both
congruent and incongruent condition.
Conclusion: High neuroticism appraises conflict and non-conflict condition under
incompatibility manner driven by prefrontal cortical top–down control.
