Zap Your Brain Into the Zone: Fast Track to Pure Focus

Whether you want to smash a forehand like Federer, or just be an Xbox hero, there is a shocking short cut to getting the brain of an expert

I’m close to tears behind my thin cover of sandbags as 20 screaming, masked men run towards me at full speed, strapped into suicide bomb vests and clutching rifles. For every one I manage to shoot dead, three new assailants pop up from nowhere. I’m clearly not shooting fast enough, and panic and incompetence are making me continually jam my rifle.

My salvation lies in the fact that my attackers are only a video, projected on screens to the front and sides. It’s the very simulation that trains US troops to take their first steps with a rifle, and everything about it has been engineered to feel like an overpowering assault. But I am failing miserably. In fact, I’m so demoralised that I’m tempted to put down the rifle and leave.

Then they put the electrodes on me.

I am in a lab in Carlsbad, California, in pursuit of an elusive mental state known as “flow” – that feeling of effortless concentration that characterises outstanding performance in all kinds of skills.

Flow has been maddeningly difficult to pin down, let alone harness, but a wealth of new technologies could soon allow us all to conjure up this state. The plan is to provide a short cut to virtuosity, slashing the amount of time it takes to master a new skill – be it tennis, playing the piano or marksmanship.

That will be welcome news to anyone embarking on the tortuous road to expertise. According to pioneering research by Anders Ericsson at Florida State University in Tallahassee, it normally takes 10,000 hours of practice to become expert in any discipline. Over that time, your brain knits together a wealth of new circuits that eventually allow you to execute the skill automatically, without consciously considering each action. Think of the way tennis champion Roger Federer, after years of training, can gracefully combine a complicated series of actions – keeping one eye on the ball and the other on his opponent, while he lines up his shot and then despatches a crippling backhand – all in one stunningly choreographed second.


Flow typically accompanies these actions. It involves a Zen-like feeling of intense concentration, with time seeming to stop as you focus completely on the activity in hand. The experience crops up repeatedly when experts describe what it feels like to be at the top of their game, and with years of practice it becomes second nature to enter that state. Yet you don’t have to be a pro to experience it – some people report the same ability to focus at a far earlier stage in their training, suggesting they are more naturally predisposed to the flow state than others. This effortless concentration should speed up progress, while the joyful feelings that come with the flow state should help take the sting out of further practice, setting such people up for future success, says Mihaly Csikszentmihalyi at Claremont Graduate University in California. Conversely, his research into the flow state in children showed that, as he puts it, “young people who didn’t enjoy the pursuit of the subject they were gifted in, whether it was mathematics or music, stopped developing their skills and reverted to mediocrity.”

Despite its potentially crucial role in the development of talent, many researchers had deemed the flow state too slippery a concept to tackle – tainted as it was with mystical, meditative connotations. In the late 1970s, Csikszentmihalyi, then a psychologist at the University of Chicago, helped change that view by showing that the state could be defined and studied empirically. In one groundbreaking study, he interviewed a few hundred talented people, including athletes, artists, chess players, rock climbers and surgeons, enabling him to pin down four key features that characterise flow.

The first is an intense and focused absorption that makes you lose all sense of time. The second is what is known as autotelicity, the sense that the activity you are engaged in is rewarding for its own sake. The third is finding the “sweet spot”, a feeling that your skills are perfectly matched to the task at hand, leaving you neither frustrated nor bored. And finally, flow is characterised by automaticity, the sense that “the piano is playing itself”, for example.

Exactly what happens in the brain during flow has been of particular interest, but it has been tricky to measure. Csikszentmihalyi took an early stab at it, using electroencephalography (EEG) to measure the brain waves of expert chess players during a game. He found that the most skilled players showed less activity in the prefrontal cortex, which is typically associated with higher cognitive processes such as working memory and verbalisation. That may seem counter-intuitive, but silencing self-critical thoughts might allow more automatic processes to take hold, which would in turn produce that effortless feeling of flow.

Later studies have confirmed these findings and revealed other neural signatures of flow. Chris Berka and her colleagues at Advanced Brain Monitoring in Carlsbad, California, for example, looked at the brain waves of Olympic archers and professional golfers. A few seconds before the archers fired off an arrow or the golfers hit the ball, the team spotted a small increase in what’s known as the alpha band, one of the frequencies that arises from the electrical noise of all the brain’s neurons (The International Journal of Sport and Society, vol 1, p 87). This surge in alpha waves, Berka says, is associated with reduced activation of the cortex, and is always more obvious in experts than in novices. “We think this represents focused attention on the target, while other sensory inputs are suppressed,” says Berka. She found that these mental changes are accompanied by slower breathing and a lower pulse rate – as you might expect from relaxed concentration.

Defining and characterising the flow state is all very well, but could a novice learn to turn off their critical faculties and focus their attention in this way, at will? If so, would it boost performance? Gabriele Wulf, a kinesiologist at the University of Nevada at Las Vegas, helped to answer this question in 1998, when she and her colleagues examined the way certain athletes move (Journal of Motor Behavior, vol 30, p 169).

At the time, she had no particular interest in the flow state. But Wulf and her colleagues found that they could quickly improve a person’s abilities by asking them to focus their attention on an external point away from their body. Aspiring skiers who were asked to do slalom-type movements on a simulator, for example, learned faster if they focused on a marked spot ahead of them. Golfers who focused on the swing of the club were about 20 per cent more accurate than those who focused on their own arms.

Wulf and her colleagues later found that an expert’s physical actions require fewer muscle movements than those of a beginner – as seen in the tight, spare motions of top-flight athletes. They also experience less mental strain, a lower heart rate and shallower breathing – all characteristics of the flow state (Human Movement Science, vol 29, p 440).

These findings were borne out in later studies of expert and novice swimmers. Novices who concentrated on an external focus – the water’s movement around their limbs – showed the same effortless grace as those with more experience, swimming faster and with a more efficient technique. Conversely, when the expert swimmers focused on their limbs, their performance declined (International Journal of Sport Science & Coaching, vol 6, p 99).

Wulf’s findings fit well with the idea that flow – and better learning – comes when you turn off conscious thought. “When you have an external focus, you achieve a more automatic type of control,” she says. “You don’t think about what you are doing, you just focus on the outcome.”

Berka has been taking a different approach to evoke the flow state – her group is training novice marksmen to use neurofeedback. Each person is hooked up to electrodes that tease out and display specific brain waves, along with a monitor that measures their heartbeat. By controlling their breathing and learning to deliberately manipulate the waveforms on the screen in front of them, the novices managed to produce the alpha waves characteristic of the flow state. This, in turn, helped them improve their accuracy at hitting the targets. In fact, the time it took to shoot like a pro fell by more than half (The International Journal of Sport and Society, vol 1, p 87).

But as I found when I tried the method, even neurofeedback has a catch. It takes time and effort to produce really thrumming alpha waves. Just when I thought I had achieved them, they evaporated and I lost my concentration. Might there be a faster way to force my brain into flow? The good news is that there, too, the answer appears to be yes.
