The Hypervigilance Rollercoaster is described as a pattern involving changes in what states?

• A. Sleep patterns
• B. Mood and arousal
• C. Alertness and fatigue
• D. Cognition

Answer: (C)

This item tests how arousal fluctuates. The “Hypervigilance Rollercoaster” describes shifts between being highly alert and being fatigued, reflecting changes in how awake and responsive a person is. That focus on alertness and fatigue makes the best answer clear: it’s about fluctuations in arousal levels, not just sleep timing, mood, or cognitive processing. Sleep patterns are about when you sleep, not the ebbs and flows of wakeful alertness. Mood and arousal mix emotional state with arousal, but the phrase emphasizes vigilance and wakefulness rather than emotion. Cognition concerns thinking processes, which can be influenced by arousal, but the core idea here is the state of being alert or fatigued.
