Which statement best differentiates simulator sickness from motion sickness?

• A. It involves only nausea
• B. It occurs only during actual flights
• C. It has no cognitive symptoms
• D. Cognitive symptoms are typically more severe and can last for several hours

Answer: (D)

The main idea is that simulator sickness arises from a visual-vestibular mismatch in a static body inside a motion-simulating environment, which strains higher-level processing and often produces prominent cognitive effects. Because your senses aren’t aligned—the eyes see motion or simulated motion while the body doesn’t move—the brain works harder to resolve the conflict. This tends to bring on cognitive symptoms such as disorientation, difficulty concentrating, mental fog, memory issues, and fatigue, and these effects can persist for hours after you’ve left the simulator. In contrast, motion sickness typically centers on autonomic and sensory symptoms like nausea, sweating, dizziness, and pallor from real motion, and these usually subside relatively quickly once the motion stops. So the distinguishing feature here is that simulator sickness often involves more severe cognitive disruption and longer-lasting symptoms, whereas motion sickness is more about autonomic symptoms with shorter duration. So the statement about cognitive symptoms being typically more severe and able to last for several hours best captures the difference.
