The purpose of this study was to investigate the relationships between personality dimensions, such as extraversion/introversion dimension, neuroticism dimension, psychoticism dimension and lie dimension and EEG responses 29 extroverted subjects and 31 introverted subjects were selected by the Eysenck Personality Questionnaire. EEG activities were measured by a ‘10/20’ system. Among 4 personality dimensions, extraversion/introversion dimension had significant correlation with EEG activities. Two regions which had significant correlation with the extraversion/ introversion dimension were anterior temporal and occipital regions. In both regions, the arousal levels were significantly lower in extroverted subjects than introverted subjects. In conclusion, there significant partial relationship between extraversion/introversion personality dimension and the cortical arousal level.
