Extraversion has been recognized as a major personality variable in contemporary psychological writings. It may be viewed as a personality dimension that describes a number of more specific personality traits, ranging from sociability and liveliness to dominance and adventure seeking. Extraversion is thought to have a biological basis associated with both cortical arousal and the dopaminergic system. 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. Extraversion has been linked with a wide range of human behaviors, from academic achievement and occupational performance to antisocial behaviors and risk taking.
