The present exploratory study was attempted to investigate the relationship between components of event-related potential (ERP) and Cloninger's personality dimensions. The ERP was measured using the auditory oddball paradigm, and personality was evaluated by Temperament and Character Inventory (TCI) in 25 healthy subjects. The results showed that P300 amplitude at Fz was significantly associated with reward dependence, and that P300 latency was positively correlated with persistence, and negatively correlated with novelty seeking. No correlations were found between N100, P200 and personality dimensions. These results indicate that personality dimension is related to information-processing in the brain. The neurobiological and psychological aspects of personality, which may relate to the P300 were considered.
