What is the relationship between extraversion and brain arousal
Our primary analysis suggests that, after multiple testing corrections, brain arousal is negatively associated with the degree of extraversion and openness to experience:People who are high in extroversion tend to seek out social stimulation and opportunities to engage.In general, the term refers to a state of being where someone recharges, or.The theory states that the brains of extroverts are naturally less stimulated, so these types have a predisposition to seek out situations and partake in behaviors that will stimulate arousal.The relationship between extraversion and physiological measures was tested on psychology undergraduate students at a university in the uk.The lower level of cortical arousal and the lower dopaminergic responsiveness found in extraverts is used to explain their greater need for activity, excitement, and general stimulation.
It is concluded that the relationships between personality, arousal and performance assumed by arousal theory are small in magnitude, which may explain inconsistencies between previous findings.And propose an inverse relationship between the degree of extraversion and cortical arousal, as sustained by a loop connecting the reticular formation with the cortex.Extraversion, neuroticism and brain function:
