How your eyes can cast your fate in a gunfight
Part one of a two-part series
By Force Science Research Center
A major new study by the Force Science Research Center for the first time has identified exactly how the “gaze patterns” of officers who are likely to win gunfights differ from those who are likely to lose them.
Winners, it is revealed, tend to anticipate an emerging threat sooner, shoot to stop it faster and more accurately, and make fewer errors in judgment because of the unique way in which they watch a potential attacker’s body as a deadly confrontation unfolds.
A key finding: Those who win lethal assaults do so, in part, because they achieve target acquisition with their firearm in a way that is directly opposite of how most officers are trained.
“This unique study shows that winning a gunfight involves more than just issues of action and reaction times,” FSRC’s executive director Dr. Bill Lewinski told Force Science News. “Where an officer is looking during an encounter, what kind of information he is picking up, and how he is processing it are also vitally important. An effective gaze control strategy can help officers minimize or defeat the action/reaction advantage that the suspect might otherwise have.
“In short, an officer’s performance can be impaired or enhanced by where his eyes and attention are focused in the midst of a deadly encounter.”
What the new study discovered about that phenomenon, Lewinski says, could have significant repercussions on law enforcement firearms training.
The study was conducted by Lewinski and Dr. Joan Vickers of Canada’s University of Calgary, a renowned researcher of the relationship between eye movement and athletic performance. They recently presented the first detailed report of their findings at the prestigious International Conference on Spatial Cognition in Rome.
Their full paper, “Gaze Control and Shooting Performance of Elite and Rookie Police Officers During a Force-on-Force Encounter,” will be posted on the Force Science website once it has been published in an academic journal. Meanwhile, FSN’s two-part series is the first disclosure to the international law enforcement community about the study’s surprising practical discoveries.
Field work for the research was conducted a year ago in the United Kingdom with the help of 24 police volunteers. Eleven were highly experienced, male veterans of an Emergency Response Team (ERT), seasoned in fighting terrorists among other assignments, with a median age of nearly 39. The rest were younger rookies (median age just over 30), seven of them female, who had completed their pre-service firearms and simulation training and were considered “ready for the street.” Both groups predominately were right-eye shooters.
The research scenario, designed by Lewinski, was based on an actual incident. One at a time the volunteers were armed with a holstered Glock pistol fitted to fire a single Simunition cartridge and told they were on duty to “provide security” at an embassy office where intelligence had indicated an armed encounter would occur that day.
About 20 feet in front of the officer being tested was a receptionist at a desk. Presently an adult male, playing the role of a civilian tourist, entered the room and engaged the receptionist in conversation regarding a problem with his passport, keeping his back to the subject officer.
Initially the exchange was polite but as the receptionist proved not to be helpful the man became increasingly agitated. About three seconds before the end of the one-minute scenario, his voice started to rise and he began cursing and slapping the table. Suddenly, in an explosion of rage, he yanked an object from under his coat and pivoted quickly.
In most instances, the object was a handgun and he fired at the officer. But randomly he spun around only with a cell phone. The volunteers were not advised in advance of this “catch” switch. They were told only that they should “handle the threat” appropriately, using their handgun.
“The suspect’s dynamic turning and shooting unfolded very rapidly,” Lewinski says, “and presented quite a challenge for any officer. We wanted to detect the clearest demonstration of operational differences, and that’s why groups of the best and the least experienced officers were chosen.”
Each volunteer went through the scenario seven times. According to the researchers, no significant change was noticed in their reactions with repetition.
During the scenario, each officer wore a light-weight, head-mounted apparatus with two sophisticated and highly sensitive computer-interactive components: 1) a small video camera that filmed the scene being played out in front of the officer from the officer’s perspective, and 2) a mobile monocular “eye tracker” that used reflection off of the officer’s cornea to precisely document his line of sight.
Just where the officer’s gaze was directed at any given split-second was overlaid on the digital image the camera was recording, in the form of a small red circle. In other words, exactly where the officer was looking, when he was looking there, in what sequence, and for how long were all captured in a continuous, time-coded format that allowed every location of his gaze to be noted and analyzed later.
A separate video camera was placed in the room to photograph each officer frontally from head to toe as he experienced and reacted to the role-playing. These images were later synced with those from the headgear. (The data collection system, developed by Vickers, is called the vision-in-action method. Samples of the recordings will be posted on the Force Science website when the academic paper is posted. For more information, see Vickers’ book, Perception, Cognition and Decision Training: The Quiet Eye in Action.)
Keeping the scenario consistent across all officers, of course, was critical for comparison purposes. So the receptionist (played by FSRC executive Patricia Thiem) and the suspect (played by Lt. Lee Edwards of the Minneapolis PD) worked extensively with an acting coach, who trained them to maintain the same timing and mannerisms across repeated performances.
The field recordings took two full weeks to complete; the subsequent analysis took months. Here are the most significant findings:
The ERT officers — considered the elite shooters in the study — strongly out-performed the rookies.
• First of all, the ERT spent significantly less time assessing the situation before drawing their gun. On whole, they drew “well before the assailant began his pivot,” Vickers reports. Most drew early and “held [their gun] at chest level before aiming.” The rookies tended to delay drawing until about a second after his turn.
• The ERT shot before the assailant got his round off 92.5 percent of the time, beating him by an average of nearly 180 milliseconds (ms). The rookies shot first only about 42 percent of the time and on average lagged behind the attacker by more than 13 ms. Responding “very poorly,” the study says, the rookies essentially “reacted to his attack, rather than being ahead of him as were the ERT during every phase of the encounter.”
• The ERT hit the assailant nearly 75 percent of the time, compared to about 54 percent — ”slightly more than chance” — for the recently trained rookies. ERT hits were in the upper torso (center mass) 62 percent of the time, versus about 48 percent for the rookies.
• In more than 60 percent of their trials, rookies fired when the assailant brandished a cell phone instead of a gun, compared to only about 18 percent for the ERT.
Anyone would expect highly experienced elites to shoot better than rank novices, but what’s impressive is the relationship that gaze and focus appeared to have to performance.
As part of their meticulous analysis of where the test subjects were looking during the last critical seven seconds of the scenario, the researchers tabulated two important factors: fixations (when an officer’s gaze was stable on an object or location within a three-degree visual angle for 100 ms or longer) and saccades (when the eyes moved rapidly from one fixed location to another for at least 66.66 ms).
Among their discoveries, these are considered most meaningful:
• The ERT officers tended to use fixations of only short duration early in the encounter, during their initial assessment and as the suspect began to pivot toward them. Then they used longer-duration fixations as they aimed and fired. “They needed less time to ‘read’ critical cues” and acquire external feedback information that “allowed them to prepare their shooting movements in advance and prevail over the assailant,” the researchers explain. Thus the ERT “were ahead of the assailant in terms of their motor phases and gaze control across all phases of the encounter.”
• “The rookies used an opposite strategy and had long-duration fixations at the outset and shorter durations as they aimed and fired.” In effect, “the rookies were behind” the suspect’s actions and were “caught by surprise.” They “used a reactive strategy where they acquired information at the last moment, which was inadequate both in terms of its content and timing for the extreme demands of the encounter.”
• “The ERT had a higher frequency of fixations than the rookies in all phases [of the scenario] except the aim/fire phase, when the ERT had fewer fixations to fewer locations than the rookies, indicative of greater focus and concentration as they aimed and fired.”
• The ERT increasingly directed their attention to the suspect’s gun hand/arm as the scenario evolved. “They increased the percent of fixations to this location from 21 percent in the assessment and early pivot phases to 71 percent during the final two seconds. On hits, the ERT directed 86 percent of their final fixations to this one location, revealing a remarkable degree of focus and concentration under fire.” And, the study explains, they had time for a final, undisturbed period of super-concentration that Vicker’s calls “the quiet eye,” which has been linked with high performance across many different genres of athletics. In this, their eye remained settled on a defined target location through trigger pull.
• “The rookies did not show the same funneling of their attention to the assailant’s gun hand/arm,” the study points out. Early on, similar to the ERT, they concentrated a minority of their fixations there. But at the time the suspect aimed and fired, only 33 percent of the rookies’ fixations were directed there, a modest and inadequate increase. And whatever quiet-eye time they exhibited was significantly lower.
Perhaps most startling, the officers’ last abrupt shift of gaze before firing was found to be radically different between the two groups.
The rookie’s final saccade, especially among those who missed when they fired, “occurred at the same time they tried to fixate the target and aim,” the study reveals. At that critical moment in the last 500 ms, the rookies in a staggering 82 percent of their tests took their eyes off the assailant and attempted to look at their own gun, trying to find or confirm sight alignment as they aimed. “This pulled them out of the gunfight for what turned out to be a significant period of time,” Lewinski says. Vickers adds: “On a high percentage of their shots, the rookies did not see the assailant as they fired,” contributing to inaccurate shooting and the misjudgment of the cell phone as a threat.
About 30 percent of the ERT also looked at their gun, but their timing was different. Most of those gaze-shifts occurred before the officers aimed, “followed by the onset of their aim and fixation on the target and firing.”
The researchers pose the possibility that the rookies’ training may have contributed to their poor performance. They were taught pistolcraft “similar to how most police officers first learn to shoot a handgun: to focus first on the rear sight, then on the front sight, and finally on the target, aligning all three before pulling the trigger.”
“This is a very time-consuming process and one that was not successful in this study,” Vickers says.
Somewhere across their training, practice, and experience, the successful ERT officers had learned what essentially is a reverse process: Their immediate and predominate focus is on the weapon carried by their attacker. With their gaze concentrated there, they bring their gun up to their line of sight and catch their sights only in their peripheral vision, a subtle “sight glimpse,” as Lewinski terms it. “They have an unconscious kinesthetic sense to know that their gun is up and positioned properly,” he says. “This is a focus strategy that Olympic shooters use,” says Vickers, “and it is simpler, faster, and more effective.”
As the assailant’s actual attack got underway, the elite officers were zeroed in on a “weapons focus.” That is, the ERT officers’ “fixations were not directed to the assailant’s centre of mass as he pivoted and fired, but to the weapon itself, which he held away from his body until the moment he fired. The ERT tracked the weapon as soon as it was visible, using a series of fixations. Because he was moving rapidly, it was only during the last few milliseconds that his centre mass presented a viable target.”
“This intense attentiveness to the weapon can have memory implications later on,” Lewinski explains. “Now we have an empirical study showing why an officer who survives a gunfight may be unable to identify a perpetrator’s face or recall other important details proximate to the shooting, such as the body position or turning action of the subject.”
Now that the study has documented important ways in which expert shooters behave, how can trainers best convey these elite skills to other officers? “FSRC plans to do more work with Dr. Vickers to identify answers to that question,” Lewinski says. “But already, these findings suggest some important changes that will point us in the right direction.”
NEXT: What will it take in terms of gaze and attention training to make police firearms skills much greater much faster?

Thanks for posting very interesting and informative.
When you have to shoot, shoot. Don't talk.

very interesting. I am still attempting to wrap my head around this though...
This confirms what I learned a long time ago when taught by an old-timer. He told me to, "Watch the hands and don't let them eye fornicate you."
I'm going to print your post out and read it over at a later date when I'm not so tired. Take care, thank you for posting this and stay safe.
Interesting read. Makes a lot of sense to me.The basics.This confirms what I learned a long time ago when taught by an old-timer. He told me to, "Watch the hands and don't let them eye fornicate you."

Ayoob was ahead of his time. 25 years ago, StressFire (1984), Chapter 7 Point Index, Page 55At that critical moment in the last 500 ms, the rookies in a staggering 82 percent of their tests took their eyes off the assailant and attempted to look at their own gun, trying to find or confirm sight alignment as they aimed. ...
About 30 percent of the ERT also looked at their gun, but their timing was different. Most of those gaze-shifts occurred before the officers aimed, “followed by the onset of their aim and fixation on the target and firing.”The "over the top sight picture" ... will allow you to "point" the gun under stress and hit what you're aiming at while your eyes are focused down range on the life-threatening target due to Tunnel Vision.

Thank you Jang. Mas is a friend of Bill's and he presents this case very well in LFI I. I have just written Bill as I am very interested in this subject. (I just retired as a quite successful head wrestling coach at a large high school) and I have an MS in Physical Education with an emphasis in motor movement.
I want to express my thanks to you again for presenting this.
I too thought of point shooting as I read this. Looks like more training for me ;) But that's never a bad thing. I was surprised though, that even when the rookies KNEW it was coming they still were slow to react.
Better to die on your feet, than to live on your knees.
When an LEO, I always tried to concentrate on a persons hands. The person may be smiling, laughing, etc., but his hands will tell you what he's really thinking.

Good information. Thanks for posting.
This same advice should work well in close encounters with someone using a knife against you. Watch the hands!!!!!
