Lumosity is a brain fitness program from Lumos Labs which is designed to improve cognitive function through a series of web-based games and exercises.
In developing Lumosity, Lumos Labs worked closely with leading neuroscientists from Stanford and UCSF to design and experimentally test the program. In a randomized, controlled study, the exercises were shown to have statistically significant effects in improving memory and attention.
Brain games are wildly popular in Japan and Europe, the Ninentendo DS Brain Age has sold millions of copies. The delivery of similar functionality online is the logical next step and although they might not be the most engaging games, that’s not the goal here.
