Lee and Aronson (1974) demonstrated that optic flow, which is the apparent motion of objects as an observer moves relative to them, could indeed affect balance and orientation. Their experiment showed that when the walls and ceiling of a room were moved, it could cause observers, including children, to lose their balance, stagger, and potentially fall, illustrating the importance of visual information in maintaining an upright position.
