Why do some introverts need low arousal according to the material?

• A. Because they respond best to fatigue
• B. Because arousal does not affect them
• C. Because their RAS is already stimulated
• D. Because they require high arousal to focus

Answer: (C)

The main idea is how arousal levels influence performance in introverts. Introverts tend to have a more active arousal system, so the reticular activating system (RAS) is already stimulated. Because the RAS is already heightened, adding more arousal can push them into overload and hinder concentration. Therefore, they benefit from low-arousal environments to stay at an optimal level of arousal for focus. This is why the statement that their RAS is already stimulated is the best fit. Fatigue isn’t the driver of arousal here, arousal does affect them, and they don’t need high arousal to focus.
