Resting brain qEEG has been used for the diagnosis of a variety of clinical disorders ranging from epilepsy to ADHD. While the technology has proven promising, research suggests that brainwave measurements are influenced by personality factors (e.g. higher levels of extraversion and neuroticism are linked with quantity and location of alpha wave activity). The present study sought to examine the relation of personality as represented by the Five Factor Model and resting brain states in a sample of 20 undergraduate students. It was expected that neuroticism would be associated with higher frontal and posterior right brain activity and extraversion with higher left frontal and right posterior activity. Findings were generally supportive of hypotheses and suggest that personality factors should be considered when interpreting qEEG data for clinical purposes.
