Lumosity

Lumosity is a brain-training software program available as a web-based application and a mobile app. Launched in 2007, Lumosity offers a suite of games designed to challenge users' cognitive abilities such as memory, attention, speed, flexibility, and problem-solving. The company states that its games are based on scientific principles of neuroplasticity, the brain's ability to reorganize itself by forming new neural connections throughout life.

Users create accounts and can choose to play a selection of games daily. Lumosity tracks user performance and provides feedback on their progress. It also offers personalized training programs that adapt to the user's performance over time, aiming to improve specific cognitive skills. The program's effectiveness has been a subject of debate and research. While some studies suggest potential benefits in specific cognitive areas, broader claims about general cognitive enhancement and prevention of cognitive decline have faced scrutiny and criticism from the scientific community.

In 2016, Lumos Labs, the company behind Lumosity, settled with the U.S. Federal Trade Commission (FTC) over allegations of deceptive advertising. The FTC found that Lumos Labs made misleading claims about the extent to which Lumosity could prevent age-related cognitive decline, slow the onset of dementia, and help users perform better at work or school. Following the settlement, Lumosity updated its marketing and claims. The platform continues to offer its games, focusing on the concept of cognitive training rather than making explicit claims about medical benefits or preventing serious cognitive diseases.
