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.
本探索性研究旨在调查事件相关电位（ERP）成分与克隆宁格人格维度之间的关系。采用听觉Oddball范式测量ERP，并通过气质与性格量表（TCI）对25名健康受试者的人格进行评估。结果显示，Fz处的P300波幅与奖赏依赖显著相关，P300潜伏期与坚持性呈正相关，与寻求新奇呈负相关。未发现N100、P200与人格维度之间存在相关性。这些结果表明人格维度与大脑中的信息处理有关。研究考虑了可能与P300相关的人格的神经生物学和心理学方面。
