Cortical brain activities related to neuroticism and extraversion in adolescence

摘要

The purpose of the study was to examine gender differences in brain activity related topersonality traits in adolescence. 50 adolescents (Mage=14.20, SD 1.97; 50% boys) wererecruited. To assess personality traits, the BFQ-C was used and for recording corticalbrain activity, EEG was applied. Stepwise regression showed that beta band in thefrontal region, theta band in the parietal region and beta band in the central region canpredict neuroticism. General Liner Model showed that gender is a factor that caninteract with parietal in theta band for predicting. Other results showed thatextraversion is predicted by theta frontal and theta temporal regions. Moreover, GLMshowed that gender is a factor that can interact to frontal in theta and temporal in betaactivities for predicting extraversion. To sum up, the outcomes of this present studyprovided a novel framework for identifying neurodevelopmental correlates of personalitytraits for further research.
