If you're talking about visual training and the quiet eye, that’s pretty straightforward. The quiet eye, for instance, is how long you look at the rim right before you shoot. The longer and more focused that final look is, the better your brain can lock in and help you make the shot. Great shooters don’t just glance at the rim — they hold their eyes on it for a moment before they start their motion. That’s the quiet eye. Some are trying to tie this into perception-action coupling, but thats a bit of a stretch. The quiet eye is about focus and intention. And what research is showing is that focusing is better than not focusing. Nothing revolutionary, but an interesting topic.
