In his book on basketball great Bill Bradley, writer John McPhee proposed that Bradley's greatest asset had little to do with speed, strength or agility. It had to do, McPhee proposed, with his eyes.
"His most remarkable natural gift ... is his vision," McPhee observed. "During a game, Bradley's eyes are always a glaze of panoptic attention."
The work of University of Notre Dame researcher Matthew Robison suggests that McPhee may have been on to something. In a recent study, Robison documented a phenomenon in eye movement—or "oculomotor dynamics"—that links a steady, focused gaze with superior levels of performance. The study is published as a pre-print on PsyArXiv.
Robison, an assistant professor in the Department of Psychology, made the discovery thanks to the unique capabilities of his lab, which includes more than a dozen precision instruments for tracking eye movement and pupil dilation. These devices capture images of the eyes every four milliseconds, providing 250 frames per second.
This ultra-detailed look at the eyes allows Robison to "read" the complex language of minute eye movement. A slight wiggle in the eye, for example, can reveal that a study participant was distracted by a stimulus entering their field of vision—even though their facial expression never altered. Or a dilation of the pupil might indicate a participant is struggling to solve a complex math problem.
Recently, though, Robison has been most interested not in why our eyes move, but in why we might—or might want to—keep them still. He was inspired to investigate the meaning of a steady gaze by the work of applied sports psychologists helping athletes achieve high levels of performance.
"Sports psychologists regularly advise that if you're about to putt, pick a spot on the back of the golf ball and keep your eyes still there for a second or two. Then hit the ball," Robison said.
"Or, if you're shooting a free throw in basketball, pick a spot on the rim and focus on it for a few seconds. Then shoot the free throw. The advice seems sound in many cases. But the causal pathway behind this phenomenon has not been thoroughly demonstrated or explained."
Robison hypothesized that a steady gaze had to do with attention control and thus would lead to better performance not only in sports but also in almost any mentally demanding activity, whether it was comprehending a difficult passage of text, solving a complex problem, remembering new information or multitasking.
To test his hypothesis, he recruited nearly 400 participants to perform a series of tasks in his lab over a two-hour period while their gaze was being recorded by eye trackers and pupilometers.
Robison found that, across the board, those participants who kept their gaze steady in the moments just before being called upon to complete a task performed with greater speed and with greater accuracy. Borrowing a term from sports psychologist Joan Vickers, Robison called this specific quality of gaze "quiet eye." He said it is more than a lack of motion.
Like Bradley's gaze that so impressed McPhee, "quiet" eyes are not just still. They are focused—able to resist distractions and remain vigilant, ready and "awake."
His work documenting quiet eye suggested another question for Robison to explore: Would it be possible to train individuals to perform better by training them not in the task itself but in developing a steadier gaze?
Robison has launched a new three-year project focused on answering that question. "Our aim is to make the benefits of 'quiet eye' available to anyone who wants to learn them," he said.
And while it will not immediately lead to Bill Bradley levels of basketball virtuosity, the benefits could be widespread. Robison hopes that "those who learn this skill are able, in turn, to sustain and control their attention, which will yield benefits for their performance in almost any complex or demanding task."
Natalie Steinhauser, a program officer at the Office of Naval Research, said she looks forward to starting this new research that bridges two aspects of her Prepared Warfighter Portfolio. Her portfolio focuses on "understanding attention control and how it impacts warfighter performance" and "accelerating and innovating training approaches to maximize warfighter readiness."
This research, she said, "brings those worlds together in hopes of training our naval warfighters to optimize their attention and, thus, performance."
