Quizplus · Accepted Answer

Hans Eysenck's theory proposes that extraverts have a lower level of cortical arousal than introverts, leading them to seek out more stimulation to increase their arousal levels. This theory has been supported by studies that have measured differences in electroencephalography (EEG) readings between extraverts and introverts, which have shown that extraverts have lower levels of cortical arousal.
