Bayesian surfing.
There is a growing body of work demonstrating that humans are close to statistically optimal in both their perception of the world and their actions on it. In this work, the authors introduce a full-body, goal-directed task similar to surfing where subjects steer an on-screen cursor with their center of pressure. They find that subjects respond to sensory uncertainty near-optimally in this task, but their behavior is highly non-linear (see Stevenson et al., doi:10.1371/journal.pcbi.1000629).
