Lumosity Brain Training: Challenge & Improve Your Mind

Researching the efficacy of Lumosity

What we did

Lumos Labs conducted a randomized study of Lumosity brain training and published the results in a peer-reviewed research journal.

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.

What we found

After 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.

These results are promising, but more research is needed to determine the connection between improved assessment scores and everyday tasks in participants’ lives.

Next questions

Future 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. As with all scientific research, there is also a risk of publication bias.
