Use your brain if you have to

In the sports literature there is disagreement: is visual information primarily used for planning goal-directed movements or for their moment-to-moment guidance during execution? There are three main arguments for the former. First, visuomotor delays may render sensorymotor updates untimely for some movements. Second, longer target fixations are associated with expertise and accuracy. Third, with practice performers become less dependent on concurrent information. I will argue that these findings are critically dependent on the participant and task under study, and that critical variables are visual timing and the ability to use information. Expert sportspeople and people with coordination difficulties are at the extremes of a normal distribution curve for visuomotor performance. I will present behavioural results to illustrate their efficient use of concurrent visual information. I will also show that more visual information is not always an advantage (even when the information is relevant to the task) with consequences for the understanding of brain function.
