What is the general term for the false perception of position or motion due to discordant orientation information?

• A. Coriolis Illusion
• B. Orientation Illusion
• C. Induced Motion
• D. Structural Illusion

Answer: (B)

Discordant orientation cues from what you see and what your vestibular system and body sensors feel can make the brain misjudge where you are or whether you’re moving. This broad misperception is called Orientation Illusion. It captures the idea that conflicting information about orientation leads to false perceptions of position or motion. The other terms describe more specific situations: Coriolis illusion is a particular vestibular spinning sensation caused by rapid head movements; Induced motion refers to perceiving motion in one object because of the movement of another; Structural illusion isn’t the standard term used for this phenomenon.
