Abstract

The purpose of this study is to find out the relationships of brain laterality, active EEG over all brain regions and personality traits by measuring EEG signals on the basis of the counseling psychology personality theories. For this study, the EEG of ninety-six college students as measured by an eight channel EEG device and analyzed through the computer and the data of their Big Five Personality Test were analyzed by statistical analysis. The result was that when theta's laterality at the prefrontal lobe is bigger, neuroticism is higher in the personality factors. On each of the brain regions, theta's activity on the left of the prefrontal lobe makes higher neuroticism but lower conscientiousness, and beta's activity on the left of the frontal lobe makes lower extroversion and openness to experience. These results showed that there are statistically meaningful relationships between the brain region activated specific EEG and individual personality or psychological traits. This study branched out into theta band while most previous studies measured in alpha and beta band. Also from these results it suggested the counseling strategy with the brain and follow-up studies.

본 연구는 상담심리학의 성격특성이론에 근거하여 좌 우뇌의 신경학적 비대칭성 및 두뇌 각 영역에서의 활성뇌파와 성격의 요인별 특성과의 관련성을 EEG측정을 통해 알아보고자 하였다. 이에 96명의 대학생들을 대상으로 8채널 EEG 장비를 이용하여 뇌파를 측정한 후 컴퓨터로 분석한 자료와 성격 5요인 질문지를 사용하여 조사한 자료를 통계 분석하였다. 그 결과 전전두엽의 쎄타파 좌 우뇌비대칭이 클수록 성격요인 중 신경증이 높은 것으로 나타났고, 각 두뇌영역별로는 전전두엽좌측의 쎄타파 활성이 클수록 신경증은 높고, 성실성은 낮아지는 것으로 나타났으며, 전두엽좌측의 베타파 활성이 클수록 외향성과 개방성이 낮아지는 것으로 나타났다. 이러한 연구결과는 두뇌영역별 특정뇌파리듬의 활성이 개인의 성격 및 심리적 특성에 유의미한 관련이 있음을 알 수 있게 한다. 기존의 연구들 대부분이 주로 알파파, 베타파 영역에서 성격과의 관련성에 대해 언급했던 것과 달리, 본 연구결과는 세타파가 성격특성과 관련이 있을 수 있음을 시사한다. 이러한 연구 결과를 토대로 두뇌관련 상담전략과 후속연구에 대해 제언하였다.
