Identifying the differences of neural correlate on N200 and P300 event related potential (ERP) components from visual stilmuli between extraversion and ambiversion type of personality

Studies that explore neurophysiological correlates with personality traits have commonly used event-related potential (ERP) during a visual oddball task with results being the main changes in the N200 and P300 components. Besides that, the science of the brain of each personality suggested the...

Mann Whitney test revealed that there is no significant difference for amplitude and latency between ambivert and extravert because less electrodes demonstrated the differences between those personalities.
