Guest post by science writer Kayt Sukel
A few years ago, I was asked to write an article about the science behind “brain games,” or computer games designed to help improve cognitive function, for a popular magazine. I spoke with a variety of scientists—including those involved with companies that were marketing these games—and also examined the (quite small number) of studies that had been published on brain game efficacy. Taken together, my piece concluded that was that there was no hard and fast evidence, to date, that brain games worked as advertised. Citing the lack of a magic bullet for aging-related cognitive decline, the editor of the magazine killed my story, saying that it felt “too negative.” The magazine’s readership, she told me, wanted to be able to “do something” about keeping age-related memory and attention problems at bay.
Who wouldn’t? Many brain training companies make bold claims about the games’ effects–suggesting that just a few minutes on the computer each day could slow cognitive decline and keep neurodegeneration at bay. With that kind of messaging, it’s easy to see why the programs have become so popular. Yet, while these supposedly “scientific” claims lack evidentiary basis, few scientists have come out publicly against them.
