Eye Tracking and the Quiet Eye
The Canadian Sport Centre explains how eye tracker captures the visual behavior of elite athletes. According to the "Quiet Eye" theory, developed by Dr. Joan Vickers of the University of Calgary, the ability to hold one's focus on a specific location can separate the elite from the near-elite athletic performer.
Research by the University of Exeter shows anxiety impairs goal-directed attentional control ("Quiet Eye" gaze-focusing period) at the expense of stimulus-driven control (more fixations of shorter duration to various targets).
