Overview: The amplitude of the auditory P3 event-related potential is reduced in patients with axes I and II disorders. Data regarding P3 amplitude and normal personality traits in healthy individuals have been inconsistent, however, although more extreme variants of dimensional traits such as neuroticism and extraversion are associated with psychiatric morbidity. Previous studies have shown that both reduced P3 amplitude and a high Neuroticism/low Extraversion-Openness-Agreeableness-Conscientiousness trait pattern are associated with the presence of, and risk for, substantial psychiatric morbidity. The results suggest that processes indexed by auditory P3 amplitude are related to these broad personality dimensions in healthy individuals.
