The concept of quiet eye originates with the personal experiences of a kinesiologist called Joan Vickers. As a student in sports science – and a keen athlete herself – Vickers always had been interested in how our athletic talents vary so much from day to day.
While playing on the university basketball team, for instance, she once scored an extraordinary 27 points within the first half of a match. Another time, she had a stunning winning streak while serving for the university volleyball team. But both miraculous performances were one-offs – each time, her magic touch disappeared the next day.
“It kept on running around my head – how could I have done that? Physically I didn’t change,” she says. On the other hand, why were the elite athletes she envied not only so good, but also so consistent?
Embarking on a PhD at the University of British Columbia, Vickers began to suspect the secret lay in the way that elite athletes see the world. She hooked a group of professional golfers up to a device that precisely monitored their eye movements as they putted their balls. She found an intriguing correlation: the better the player (as measured by their golfing handicap) the longer and steadier their gaze on the ball just before, and then during, their strike. Novices, by contrast, tended to shift their focus between different areas of the scene, with each fixation lasting for shorter periods of time.
