As of November 2014, there is not enough scientific research to conclude that "Lumosity" improves a user's cognitive abilities. An analysis of 23 brain-training studies found that while players got better at the specific games they were playing, the skills did not transfer to other tasks.
A 2010 study that tracked 11,000 adults over a six-week period concluded that its participants only improved at the games themselves because of familiarity. The improvements in reasoning, memory, planning and visuospatial skills did not carry over to other areas or tasks. This does not mean that claims made by "Lumosity" and other brain-training programs are false. More thorough and conclusive research is needed, however, to substantiate the claims. Brain-training games are based on the science of neuroplasticity.
