What is the formal definition of the quiet eye?
For a given motor task, the quiet eye is the final fixation or tracking gaze that is located on a specific location or object in the visuo-motor workspace within a minimum 3 of visual angle (or less) for a minimum of 100 ms. The onset of the quiet eye occurs prior to the final movement in the task. The offset of the quiet eye occurs when the gaze deviates off the object or location by more than 3 of visual angle (or less) for a minimum of 100 ms, therefore the quiet eye can carry through and beyond the final movement of the task. The quiet eye of elite performers is significantly longer than that of near-elite or lower skilled performers, meaning those who consistently achieve high levels have learned to fixate or track critical objects or locations for longer durations irrespective of the conditions encountered. The quiet eye onset of elite performers is invariably earlier; elite performers have found a way to see critical visual information earlier than near-elite and lower skilled p
