spatial disorientationInability to determine one's true body position, motion, and altitude (or, in water, depth) relative to the Earth or one's surroundings.

The senses may not perceive gradual changes in motion and may overestimate the degree of abrupt changes and overcompensate when motion stops. Airplane pilots and divers also contend with apparent changes in gravitational pull, which can lead to dangerous situations and must be overcome by training. See also inner ear; proprioception. |
