Why do extroverts need high arousal according to the material?

• A. Low arousal is sufficient
• B. They perform best with no stimulation
• C. Arousal has no effect
• D. Optimal midpoint

Answer: (D)

Arousal and performance follow an inverted-U pattern: as arousal rises, performance improves up to a peak, then declines if arousal becomes too high. Extroverts tend to seek more stimulation, so their peak occurs at a higher arousal level than introverts. But this peak is still in a middle range—neither too low nor too extreme. So the material describes extroverts as performing best at an optimal midpoint of arousal, where there is enough stimulation to activate them without overwhelming them. Low arousal or no stimulation would not maximize their performance, and arousal at extremes would hinder it.
