Psychophysiological antecedents of personality

Personality development has been the focus of interest for many psychiatric researchers with divergent views. Recent years have brought a resurgence of interest in personality and its comorbidity with Axis I disorders. Biological approaches provide an important and effective tool in exploring this domain. Psychophysiologists have applied various paradigms to study individual differences, but results have been inconsistent. This paper reviews the relationship of measures such as electroencephalography, evoked potential, and autonomic function with personality, especially psychopathy. Further well-designed studies are needed to explain prior findings. The use of a dimensional approach to personality and learning is also described, with recommendations for future research.
