Document Summary
Information that remains constant even when the observer is moving. Describe its role in somersaulting and why there is a difference between novices and experts when they close their eyes: when a person makes a movement, that movement creates information, and is used. In somersaulting, if a gymnast has their eyes open and started off too slow, they know to finish the rest of the move more quickly using in-the-air corrections to their trajectory. Having their eyes closed only effects the performance experts, not novices, as only experts have learned to coordinate their movements with their perceptions: describe the swinging room experiments. What principles do they illustrate: our ability to stand still and keep our balance is affected by information provided by our vision, in both keeping balance, and losing it. Vision is a powerful determinant of balance, that it can override inner ear information and receptors in the muscles and joints.
