Co-founded by Michael Scanlon after he abandoned his neuroscience PhD at Stanford University, California , the business also has an extensive research programme that studies the effects of computerised cognitive training as well as conducting experiments over the web. Some ambitious parents on this side of the Atlantic have started using the games in place of hiring a private tutor to improve their children's academic scores. And there is anecdotal evidence that keeping a brain lively is helpful in staving off early-onset dementia.
But do such initiatives have any kind of scientific basis? The evidence appears to be contradictory. A study by the psychologist Susanne Jaeggi found that memory training increased intelligence and implied that a person could boost their IQ by a full point per hour of training. However, when a group of psychologists working at Georgia Tech set out to replicate her findings with tougher controls, there was no evidence for a rise in intelligence.
Meanwhile, a study by the neuroscientist Dr Adrian Owen , which tracked 11, adults over a six-week computer-based training regime designed to improve reasoning, memory, planning, visuospatial skills and attention, reported benefits in executing the tasks themselves but little general advantage in other areas.
Owen concluded that regular players of brain games got better at the games themselves through familiarity rather than showing any marked improvement in fluid intelligence the ability to solve novel problems and adapt to new situations as opposed to accumulating knowledge. In an attempt to sort out the hype from the reality, I embarked on my own experiment — albeit an experiment with an unimpressive cohort of one and without the controls that would be necessary to get the results peer-reviewed in any respectable scientific publication.
The idea was that I'd measure my intelligence at the start of the month using a variety of tests developed by the Medical Research Council at Cambridge University , designed to give a more sophisticated take on the brain's bn neurons than a single IQ test. I would then embark on a rigorous routine of brain training with Lumosity, doing regular exercises designed to make me journalism's answer to Professor Stephen Hawking.
At the end of the month, I'd take the intelligence tests again and see if there was any improvement. This is because such improvements may be specific to the exact tasks that are trained and consequently should not be classified as learning unless a generalised effect is shown. Sitting down to take the initial intelligence test, I am fairly confident.
I have a degree and good A-levels. Occasionally, I even get a few questions right on University Challenge. But it turns out to be much harder than expected: a battery of complex, time-pressure tests involving flashing shapes trying to work out which overlapping triangles are exactly the same size and long number sequences. One of them, called "Double Trouble" requires me to identify the colour a particular word is written in. Which sounds easy, until you realise that the words in question are "red", written in blue, or "blue", written in red.
Even trying to explain the games to someone else taxes my intelligence. The process isn't helped by the fact that I'm at work and keep getting interrupted by colleagues who, not unreasonably, assume that I'm simply time-wasting. The excuse "Actually, I'm training my brain" doesn't cut much ice in a busy newsroom. My scores, when they are calculated, are pretty pathetic. I'm in the top half of the population for planning. I take a couple of days to recover and then I sign up to Lumosity.
The Lumosity games are far less intimidating. An effort has been made to make them entertaining rather than hardcore versions of the plus.
They are short and sweet and include plenty of encouragement — gold stars leap across the screen when I do something right. Having said that, it's difficult to fit a minute session into my daily life. I don't find the games sufficiently interesting to get out of bed and do them each morning, so my training is rather sporadic — more like once a week than once every 24 hours.
But regular monitoring of my performance by Lumosity shows that I gradually improve in all the games the more I play them. In an interview last year, Hambrick said brain-training games are "designed to tap into this ability to control attention. Their idea is that if we can improve the ability to control attention then we can, by extension, improve people's intelligence Most research that suggests brain-training works is fraught with difficulties: little has been peer-reviewed or conducted alongside control groups.
Several companies use scans of brains "lighting up" to support claims that their programmes are effective, but these simply show a measure of the energy that the brain is using rather than providing any evidence that the brain is being altered in any long-term way. Moreover, it is unclear whether training benefits are only evident for certain sectors of the population — for example children, patients or older people.
A moment later a large, disheveled man in a stained three-piece suit, carrying a copy of Soldier of Fortune magazine under his arm, burst through my door.
He was so agitated and so clearly hungover that I wondered how I could possibly help this hulking man. I asked him to take a seat, and tell me what I could do for him. His name was Tom.
Ten years earlier he had been in the Marines, doing his service in Vietnam. He had spent the holiday weekend holed up in his downtown-Boston law office, drinking and looking at old photographs, rather than with his family. When he got upset he was afraid to be around his family because he behaved like a monster with his wife and two young boys.
The noise of his kids made him so agitated that he would storm out of the house to keep himself from hurting them. Only drinking himself into oblivion or riding his Harley-Davidson at dangerously high speeds helped him to calm down. He also had terrifying flashbacks in which he saw dead Vietnamese children. The nightmares were so horrible that he dreaded falling asleep and he often stayed up for most of the night, drinking. In the morning his wife would find him passed out on the living room couch, and she and the boys had to tiptoe around him while she made them breakfast before taking them to school.
Filling me in on his background, Tom said that he had graduated from high school in , the valedictorian of his class. In line with his family tradition of military service he enlisted in the Marine Corps immediately after graduation. Athletic, intelligent, and an obvious leader, Tom felt powerful and effective after finishing basic training, a member of a team that was prepared for just about anything.
In Vietnam he quickly became a platoon leader, in charge of eight other Marines.
Surviving slogging through the mud while being strafed by machine-gun fire can leave people feeling pretty good about themselves—and their comrades. At the end of his tour of duty Tom was honorably discharged, and all he wanted was to put Vietnam behind him. He attended college on the GI Bill, graduated from law school, married his high school sweetheart, and had two sons.
Tom was upset by how difficult it was to feel any real affection for his wife, even though her letters had kept him alive in the madness of the jungle.

Tom went through the motions of living a normal life, hoping that by faking it he would learn to become his old self again. Although Tom was the first veteran I had ever encountered on a professional basis, many aspects of his story were familiar to me. I grew up in postwar Holland, playing in bombed-out buildings, the son of a man who had been such an outspoken opponent of the Nazis that he had been sent to an internment camp.
My father never talked about his war experiences, but he was given to outbursts of explosive rage that stunned me as a little boy. How could the man I heard quietly going down the stairs every morning to pray and read the Bible while the rest of the family slept have such a terrifying temper? How could someone whose life was devoted to the pursuit of social justice be so filled with anger? I witnessed the same puzzling behavior in my uncle, who had been captured by the Japanese in the Dutch East Indies now Indonesia and sent as a slave laborer to Burma, where he worked on the famous bridge over the river Kwai.
He also rarely mentioned the war, and he, too, often erupted into uncontrollable rages. As I listened to Tom, I wondered if my uncle and my father had had nightmares and flashbacks—if they, too, had felt disconnected from their loved ones and unable to find any real pleasure in their lives. Somewhere in the back of my mind there must also have been my memories of my frightened—and often frightening—mother, whose own childhood trauma was sometimes alluded to and, I now believe, was frequently reenacted.
She had the unnerving habit of fainting when I asked her what her life was like as a little girl and then blaming me for making her so upset. Reassured by my obvious interest, Tom settled down to tell me just how scared and confused he was. He was afraid that he was becoming just like his father, who was always angry and rarely talked with his children—except to compare them unfavorably with his comrades who had lost their lives around Christmas , during the Battle of the Bulge. I had also participated in some early research on the beneficial effects of the psychoactive drugs that were just coming into use in the s.
I scheduled Tom for a follow-up visit two weeks later. When he returned for his appointment, I eagerly asked Tom how the medicines had worked. Trying to conceal my irritation, I asked him why.
I need to be a living memorial to my friends who died in Vietnam. How had that happened, and what could we do about it? That morning I realized I would probably spend the rest of my professional life trying to unravel the mysteries of trauma. How do horrific experiences cause people to become hopelessly stuck in the past? Before the ambush in the rice paddy, Tom had been a devoted and loyal friend, someone who enjoyed life, with many interests and pleasures. In one terrifying moment, trauma had transformed everything.
