People hoping to get smarter by playing brain games might be wasting their money, a study published online in the journal Nature shows. The study, conducted jointly by British researchers and the BBC, recruited viewers of a BBC science program to either play commercial brain-training programs or spend time on other computer-based problem-solving tasks. They found no improvement in either group’s general cognitive abilities. From a related article in Nature:
There were absolutely no transfer effects” from the training tasks to more general tests of cognition, says Adrian Owen, a neuroscientist at the Medical Research Council (MRC) Cognition and Brian Sciences Unit in Cambridge, UK, who led the study. “I think the expectation that practising a broad range of cognitive tasks to get yourself smarter is completely unsupported.”
Commercial brain games have multiplied in recent years, targeting aging Baby Boomers who seek to keep their brains sharp and stave off dementia. Many firms boast vast benefits from playing their games, even though research is still ambivalent on whether or not they help.
