What phenomenon can induce a sense of spinning when there is no actual rotation occurring?

• A. Oculogravic illusion
• B. The leans
• C. Coriolis illusion
• D. Somatogravic illusion

Answer: (C)

The phenomenon that induces a sense of spinning when there is no actual rotation occurring is best described by the Coriolis illusion. This occurs when an individual experiences conflicting sensory inputs, typically when a change in head position takes place while in motion, such as during flight maneuvers. The inner ear’s semicircular canals, which are responsible for detecting rotational movement, may misinterpret the signals from the vestibular system, leading to the perception of spinning even when the body is not in fact rotating. The Coriolis illusion specifically arises during abrupt maneuvers or changes in direction and can create disorientation. This is particularly relevant to pilots or individuals in high-motion environments, where their physiological responses can misinterpret the actual movement of the aircraft relative to their head movements. Understanding this phenomenon is crucial for recognizing and mitigating disorientation in aerospace environments.
