Information-based regulation of high-velocity foot-targeting tasks

Judging time-to-contact with a target is an important criterion for avoiding harm in everyday walking and running tasks, and maximising performance in high-velocity sporting tasks. Visual regulation of step length decreases at higher approach speeds in everyday gait tasks, whereas expert performers of sporting tasks are capable of increasing visual regulation at higher approach speeds. The performance of very difficult vaults in gymnastics, for example, requires increased visual regulation of the fast running approach.
