본 연구는 특성(trait) 이론에 기반한 Eysenck의 EPQ-R 설문지와 EEG 변수들간의 상관 관계에 대한 실험적 연구로서, 피험자들은 한국판 EPQ-R 설문지를 작성하였고, 2회에 걸쳐 눈을 감은 조건, 눈을 뜬 조건, 암산과제 수행조건에서 EEG를 측정하였다. Neuroticism 은 눈을 뜬 조건에서 theta 파와 부적 상관을 보였으며, Psychoticism 은 눈을 감은 조건에서 alpha파와 정적상관, delta파와 부적 상관을 보였는데, 이것은 Robinson(2001)의 이론과 일치하는 결과이다.

This study is an experimental study about the relationship between EEG and personality dimensions. Subjects were 70 healthy undergraduate students (32 males, 38 females) The Korean version of Eysencks Personality Questionnaire-Revised (EPQ-R) were used. EEGs were recorded in two different conditions (eyes open and eyes closed). To obtain more tellable data, EEG recordings of subjects were replicated 6 weeks later. The analytical methods used in the present study rendered two coincident tendencies: Theta with neuroticism relationship in eyes closed condition, and alpha-delta with psychoticism relationship in eyes closed condition. These results generally support the theory of Robinson (2001) that delta, theta, and alpha waves are associated with activity of brainstem, limbic system, and thalamo-cortical arousal system, and that thalamo-cortical alpha system has inhibitory effects on brainstem delta system.
