The purpose of this study was to investigate the personality traits in constitutional types. The Questionnaire for the Sasang Constitution Classification Ⅱ and Eysenck Personality Questionnaire were completed by 155 university students. Statistical analyses of the Questionnaire for the Sasang Constitution Classification Ⅱ and Eysenck Personality Questionnaire scale scores and results are as follows : First, Personality differences in constitutional types are revealed significantly with respect to Eysenck Personality Questionnaire scales such as neuroticism, addiction, and criminality. Second, there is a significant difference between Eum(음) type and Yang(양) type along psychoticism and neuroticism. Third, sex difference is significant along the dimension of extraverion-intraversion.

Objectives : The objective of this study was to examine the biopsychological traits of each Sasang type from a personality theory perspective. Methods : A review of different theories of personality is provided, in addition to review of ten previous studies on the psychological characteristics of the Sasang types. Results : 1. Similarities and differences were found between Sasang typology and Western theories of personality. 2. The prevalence of Sasang type was 28:36:36 (So-Yang:Tae-Eum:So-Eum), and the majority of the study sample were males in their twenties. 3. The Yin-Yang and Large-Small axes of Sasang typology were comparable to Eysenck's Extraversion and Neuroticism dimension. So-Yang type showed high extraversion and low neuroticism, and So-Eum type exhibited low extraversion and high neuroticism. Tae-Eum type was extravert and neurotic, and highly distinctive in such physical traits as Body Mass Index and blood triglyceride concentration. 4. We make recommendations for future studies on Sasang typology within a biopsychosocial and cognitive framework. Conclusions : This study demonstrates the possibility of Sasang typology being explicable from a cross-cultural biopsychosocial theory.

This study was proposed as an exploratory study for understanding the biological bases and structures of three personality models: Eysenck's PEN model, Gray's BIS/BAS model, and Costa & McCrae's Five Factor Model, which was chosen as the major descriptive model regardless of its biological bases. Besides, Eysenck's impulsivity scale, IVE, was added to demonstrate the relationship of P and impulsivity. Concerning personality, most previous reports have explored the relationships between P300 and the introversion-extraversion of Eysenck's theory because of its putative biological bases. In the present study, forty-eight undergraduate took four personality batteries (ERQ-R, NEO-Pl-R, BIS/BAS, and IVE). Two types of oddball tasks including different stimulus duration were used to induce ERPs (50ms for task 1, 300ms for task 2). Distributional topographies of correlation coefficients with personality traits and ERP components were drawn, and considered for the consistent interpretation of the personality model structures. Even though all equivalences for extraversion of personality batteries showed similarities for their intra-correlation, their correlations with P3 amplitudes were dissociate. Eysenck's E might not be the proper psychometric measure for elucidating its biological bases. The present study supported the negative relationship of P3 amplitude and extraversion, which is the consensus of previous studies. Neuroticism and Psychoticism showed correlations with the earlier sensory processing components such as N1 and P2. This result might explain the reason why most of studies have failed to find biological connections relating them. Interaction between gender and personality traits should be considered for the interpretation of correlations. Two types of auditory stimulus duration had different sensitivity to personality traits.

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.
