Abstract

This study assessed whether frontal brain asymmetry(FBA) could predict affective style and personality trait. Electroencephalographic(EEG) activity was recorded from 23 right-handed female adults participants during eight 1-min baseline resting periods. Four baselines were conducted with eyes open, and four were administered with eyes closed. Counterbalanced orders were used for the eyes-open and eyes-dosed conditions of the resting baselines. Mean alpha power asymmetry was extracted in midfrontal(F3, F4), lateral frontal(F7, F8), and anterior temporal(T3, T4) regions. For lateral frontal region, but not the midfrontal and anterior regions, there was a significant relationship between relative left hemispheric activation and extraversion. For midfrontal and lateral frontal regions, there was a significant relationship between relative right hemispheric activation and depression. Theoretical and methodological implications of these findings are discussed.
