If you enjoy the games, by all means continue. Or those suffering from brain trauma and individuals with learning disabilities. In this age of tablets and mobile devices, it's unfortunate that something so readily available cannot help us exercise our minds in ways that may benefit us beyond the screen.Īnd these revelations may be especially bad news for many who rely on apps like Lumosity everyday-the elderly attempting to ward off dementia, for example. And it certainly won't raise your IQ by any significant amount. In other words, according to these studies, it seems that remembering which shape came before the circle in the sequence will not help you remember that one last item on your grocery list as you're out shopping. Monica Melby-Lervåg and Charles Hulme of University of Oslo concluded that brain-training programs did indeed produce short-term, highly specific improvements in the task at hand, but with no generalized improvements to overall intelligence, memory, attention, or other cognitive ability. When Adrian Owen and colleagues of Cambridge University reported similar results after a six-week online cognitive training regime using 11,400 participants, he attributed these task improvements to familiarity-not a true change in cognitive ability.Īnd a recent meta-analysis of 23 studies confirmed these and others' findings. Again, though, the researchers did note that performance on the specific tasks improved. Focusing on working memory and abstract problem-solving, they found that even training for up to 20 days resulted in no significant improvement in mental capacity. Their study was published last May.Īnother investigation, published in December by a group at Case Western Reserve University, employed a similar placebo-controlled design. They also had two control groups: one that underwent placebo training, and one that did no testing whatsoever.Īfter 20 sessions, Redick found that while participants improved performance on the tasks at hand, their newfound abilities never actually transferred to any global measure of intelligence or cognition. This time, unlike Jaeggi's study, they tested 17 different cognitive tasks, including tasks for fluid intelligence, multitasking, working memory, and perceptual speed. With a skeptical eye, they attempted to replicate Jaeggi's findings. Wow!īut Thomas Redick and colleagues at Georgia Tech thought it sounded too good to be true. Lumosity has even put out a fancy PDF describing the science behind their games and changes in individuals' BPT (brain performance test) scores before and after training.Ī year after Lumosity's official launch in 2007, Susanne Jaeggi and colleagues at Columbia University published a study suggesting that memory training not only enhanced short-term memory ability, but actually boosted one's IQ an entire point per hour of training. "Lumosity is based on the science of neuroplasticity," the commercials tout, and Lumosity's website advertises its ability to "train memory and attention" through a "personalized training program." This plan includes more than 40 games designed to boost memory, flexibility, attention, processing speed, and general problem-solving ability. Since then, the company has reached more than 35 million people and this time last year the company's mobile app was being downloaded nearly 50,000 times a day. He started up the company in 2005 with Kunal Sarkar and David Drescher, after dropping out of his neuroscience Ph.D. Lumosity co-founder Michael Scanlon means well, though. Unfortunately, despite the growing popularity of brain-training apps and programs like Lumosity, CogniFit, CogMed, and Jungle Memory, I'm not going to find any help here. And I didn't remember my friend's birthday until logging into Facebook-and I'm always the one people rely on to remember birthdays. I nearly forgot about the paper I had to review this week until I saw the deadline looming on my desk calendar. This morning I poured myself a thermos of coffee and left for lab, abandoning it on the kitchen counter. I'm not old by any means, but I've become a little more forgetful lately.
