As with all scientific research, there is also a risk of publication bias. These results are promising, but more research is needed to determine the connection between improved assessment scores and everyday tasks in participants' lives.įuture research should address the risk of inadvertent experimenter bias and the risk of attrition bias in this study, as both the Lumosity and crossword groups had approximately 50% attrition rate.
The chill game features more than 6,000 puzzles set on lovely backgrounds, including fields of wildflowers and fall leaves. In it, half of the 4,715 participants who completed the study trained five days per week, for fifteen minutes each day on Lumosity while the other half did online crossword puzzles as an active control.Īfter 10 weeks, Lumosity users improved more than the control group on our assessments of working memory, short term memory, processing speed, problem solving, fluid reasoning, and overall cognitive function. See how many words you can form with a set group of four to seven letters to fill up a crossword grid, earning extra points for bonus words you might find. Lumos Labs conducted a randomized study of Lumosity brain training and published the results in a peer-reviewed research journal.
