Review: The Quiet Eye in Sports Performance—Is the Quiet Eye the Ultimate Explanation or Only the Beginning?

SIGNIFICANCE: The quiet eye is a gaze behavior that seems to differentiate both expert-novice performance and successful and unsuccessful performance in experts; however, the quiet eye may only represent one aspect of the perceptual-cognitive expertise differences that exist between athletes and nonathletes.Research suggests that expert-novice differences in vision and visual-motor coordination skills exist between athletes and nonathletes, although the underlying mechanisms driving these differences are not well understood. The quiet eye is the final fixation or tracking gaze made before the initiation of the action of importance in a motor coordination task and is quite possibly the most well-studied vision strategy variable in sport. The quiet eye has been shown to be a key component of both expert ability and successful performance. However, the quiet eye is not without its criticisms, and the perceptual mechanisms underlying this unique gaze behavior are not yet well understood. The question that remains to be answered is whether the differences in vision and visual-motor coordination skills that exist between athletes and nonathletes can be explained by the quiet eye alone or if the explanation is more complicated.
