Abstract

Openness to experience as a personality trait has been acknowledged as correlated with cognitive abilities and characteristics that motivate individuals for intellectual exploration and nourish creative behaviors. The verbal abilities of high Openness individuals, as more flexible and efficient semantic retrieval, seem to underlie their intellectual advantages and achievements. Yet no study so far has portrayed and correlated Openness with real-time semantic retrieval and processing. In this study, we examine how Openness affects categorical and featural semantic information processing in an Event-Related Potential experiment using a category membership verification task. Category typicality and featural semantic relatedness were manipulated for the true/false targets in the four conditions of category-target pairs: High-Typical (HT), Low-Typical (LT), Related-Violation (RV), Non- Related Violation (NRV). Participants of High-/Low- Openness exhibited different ERP patterns on frontal P2 and N400. Only in HO participants, HTs elicit significantly more positive P2, and NRVs were distinguished from the true exemplars at P2. On N400, condition main effect was significant for both groups, with HTs elicited the most positive N400 and the NRV the most negative; but LO participants showed no significant difference in the RV- NRV comparison. In addition, N400 effects on HT-NRV, LT-NRV, RV-NRV were positively correlated with Openness scores. These results may suggest finer and more proactive information processing in high-openness individuals. Moreover, Openness may reflect different cognitive styles in information processing shown even at the basic, categorical level. These findings extend the understanding of the cognitive factors modulating language processing from the perspective of endogenous factors such as personality traits.
