The association between personality and resting brain activity was investigated. Personality was assessed using the NEO-Five-factor Inventory (NEO-FFI) and resting brain activity was indexed by eyes closed EEG spectral magnitude from four frequency bands over the entire cortex. Results suggest that there are differences between males and females in the NEO-FFI personality traits. The NEO FFI traits were associated with lower frequency brain activity in both males and females. Mild significant and consistent associations were found between delta and theta activity across all cortical regions with Extraversion and Conscientiousness. There were few associations between personality traits and alpha and beta activity, this was shown in males only. Fewer associations between personality and faster frequency bands such as alpha may be due to the methodological problem of using fixed alpha bands. Multiple regression analyses showed that individual alpha frequencies had a greater contribution to personality traits than fixed band alpha waves.
研究了人格与静息脑活动之间的关联。使用NEO五因素问卷（NEO-FFI）评估人格，静息脑活动通过整个皮层四个频段闭眼脑电图频谱幅度来索引。结果表明，男性和女性在NEO-FFI人格特质上存在差异。NEO-FFI特质与男性和女性较低频率的脑活动相关。在所有皮层区域，外向性和尽责性与δ波和θ波活动之间存在轻度显著且一致的关联。人格特质与α波和β波活动之间的关联较少，仅在男性中显示。人格与更快频率波段（如α波）之间的关联较少可能是由于使用固定α波段的方法学问题。多元回归分析表明，个体α频率对人格特质的贡献大于固定波段α波。
