Answer:
Her brain adjusts perceived movement for actual head movement.
Step-by-step explanation:
This is the answer that best explains why the ballerina does not perceive the room as moving. When we move our heads, the environmental images that are received by the eyes change. However, we are still able to perceive the world as stable. This is because the brain is able to correct the changes in visual information by adjusting perceived movement for actual head movement. This process can best be observed in the brain through the use of functional magnetic resonance imaging (fMRI).
