Psychophysiological correlates of the NEO PI-R openness, Agreeableness andConscientiousness: preliminary results

Eysenck (1983) has previously proposed biological mechanisms for his three personality dimensions. From a psychometric perspective there has been a gr owing acceptance of a five-factor model of personality incorporating two of Eysenck's dimensions Extraversion (E) and Neuroticism (N) together with Op enness to Experience (O), Agreeableness (A) and Conscientiousness (C). Desp ite the growing acceptance of the 'Big 5' model of personality there has be en very few studies that have examined the biological basis of O, A and C. In an exploratory study we report the correlations between photic driving a t alpha, beta-1, beta-5 delta and theta bands and O, A and C from the NEO P I-R in 16 participants. Significant correlations between the EEG at frontal , occipital-parietal and central-temporal areas at different driving freque ncies with O, A and C are discussed. (C) 2001 Elsevier Science B.V.
