Those who used Lumosity to supplement their regular curriculum, the advertisement said, “improved more than a control group on a battery of cognitive assessments.” Advertisements also noted a study of more than 1,200 students in 40 schools. Advertisements pointed to studies that suggested the training could improve students’ math skills, including for girls with Turner syndrome, a genetic disorder that can result in cognitive impairments, particularly in math.
In FTC documents, investigators noted Lumosity offers 40 different games that purported to target specific brain areas, using 10- to 15-minute sessions several days a week (at costs ranging from $14.95 a month to nearly $300 for a lifetime subscription). The company also built up a network of researchers, dubbed the Human Cognition Project, to dig through the data, and presented its research at conferences such as the Society for Neuroscience.

Lumos Labs declined to comment for this story, but its advertisements said outright: “Brain training has the potential to change lives.” Through the Lumosity Education Access Program, Lumos Labs provided free copies of the games to students in more than 500 schools, in part to help build a research base to prove the interventions’ effectiveness.
Worldwide, the market could top $700 million, it says. Since 2013, the business research firm MarketsandMarkets estimates the “brain training” market has grown from $48.5 million in annual revenues to more than $67 million in North America alone, and it is projected to grow to nearly $200 million by 2020. “I think these initial promising results were taken to mean there were very strong cognitive results and changing could change your life.” “The claims of scientists and the claims of companies-I don’t think they differ too much, unfortunately,” Dougherty said. In the early 2000s, neuroscientists and cognitive psychologists studying neuroplasticity found evidence to suggest working-memory capacity could be expanded in other ways, too. Working-memory capacity naturally expands as a child grows-12-year-olds can handle about twice as many individual pieces of information as 7-year-olds, for example. Lumosity is one of the best-known of a slew of new app- and computer-based programs intended to help students improve working memory, the system the brain uses to hold information during decisionmaking and analysis. “We may in the next year or two be bringing other cases for similar kinds of brain training for children.” Booming Industry

“We are hoping to crack down on overhyped claims in this area,” said Michelle Rusk, a lawyer in the FTC’s bureau of consumer protection. The Every Student Succeeds Act has created a tiered evidence structure to help states and districts evaluate programs’ effectiveness in nascent research areas like memory training, but actions against Lumosity and Jungle Rangers give warning to researchers and educators alike that the promise of some interventions can turn into hype. A judge found that the company’s in-house research did not prove its video games could “improve school, work, and athletic performance” or protect against cognitive impairments caused by attention deficit disorders, traumatic brain injury, pediatric chemotherapy, or adult dementia as its advertisements had claimed.Įarlier in the year, the FTC also settled with the Texas-based Focus Education, which inappropriately claimed its Jungle Rangers computer game had “scientifically proven memory- and attention-training exercises” that give students “the ability to focus, complete school work, homework, and to stay on task.” Last month, it announced a $2 million settlement and $50 million judgement for misleading advertising against Lumos Labs Inc., the creators of Lumosity, a suite of computer- and app-based brain-training programs. Last year, the FTC declared open season on brain-training programs, both those directed at classrooms and for general public use. So-called “brain training” programs designed to help boost students’ attention and working memory are coming under scrutiny from the Federal Trade Commission, as some claims have outpaced both the initial hopes and subsequent evidence.
