How does Eysenck use activity occurring in the cerebral cortex to explain the difference between introverts and extraverts?
What will be an ideal response?
When the cerebral cortex is highly activated, the person is alert. When it's only slightly activated, the person may feel sluggish or drowsy. Eysenck argued that introverts have higher base levels of cerebral cortex activity and that they may become overstimulated quite easily because of this. They may avoid social interaction to avoid such overstimulation. Extraverts (who have lower base levels of cerebral cortex activity), on the other hand, may seek out social contact to increase their level of arousal.
