Psychophysiological correlates of the NEO PI-R openness, agreeableness and conscientiousness: preliminary results.

Eysenck (1983) has previously proposed biological mechanisms for his three personality dimensions. From a psychometric perspective there has been a growing acceptance of a five-factor model of personality incorporating two of Eysenck's dimensions Extraversion (E) and Neuroticism (N) together with Openness to Experience (O), Agreeableness (A) and Conscientiousness (C). Despite the growing acceptance of the 'Big 5' model of personality there has been 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 at alpha, beta-1, beta-2, delta and theta bands and O, A and C from the NEO PI-R in 16 participants. Significant correlations between the EEG at frontal, occipital-parietal and central-temporal areas at different driving frequencies with O, A and C are discussed.
