Lumosity is an online brain training and neuroscience[citation needed] research company based in San Francisco, California. Lumosity offers a brain training program consisting of games in the areas of memory, attention, flexibility, speed of processing, and problem solving.[citation needed]

History[edit]

Lumos Labs was founded in 2005 by Kunal Sarkar, Michael Scanlon, and David Drescher.[1] Lumosity.com launched in 2007 and, as of January 2015, has 70 million members.[2][3]

Financials[edit]

The company raised $400,000 in capital from angel investors in 2007,[4] a Series A of $3 million from Harrison Metal Capital, FirstMark Capital and Norwest Venture Partners in 2008,[5] a Series C of $32.5 million led by Menlo Ventures,[6] and a Series D of $31.5 million led by Discovery Communications with participation from existing investors.[7]

Effectiveness[edit]

Studies of Lumosity's effectiveness have shown mixed results. Lumos Labs website lists five independent research studies supporting benefits of Lumosity brain games or Lumosity-like customized programs specially developed for researchers:

Researcher Julia Mayas from National University of Distance Education in Madrid, Spain found a significant reduction of distraction and an increase of alertness in 15 elderly healthy adults after 20 one-hour training sessions using Lumosity in comparison to a control group of 12. The authors conclude that these results suggest neurocognitive plasticity in the old human brain.[8]

Psychologists Maurice Finn and Skye McDonald from the University of New South Wales used Lumosity training with patients with mild cognitive impairment. Results indicated that participants were able to improve their performance across a range of tasks with training. There was some evidence of generalization of training to a measure of visual sustained attention. Yet, there were no significant effects of training on self-reported everyday memory functioning or mood.[9]

Stanford University researcher Shelli Kesler worked with Lumos Labs to create customized training programs for cancer and Turner syndrome patients:

  • Kesler et al. conducted study of 23 paediatric cancer survivors and found improved cognitive performance and corresponding increases in brain activity in the pre-frontal cortex following training with customized program by Lumos Labs. Participants showed significantly improved processing speed, cognitive flexibility, verbal and visual declarative memory scores.[10]
  • Kesler et al. also demonstrated enhanced math skills and cognitive performance with corresponding changes in brain activity in individuals with Turner syndrome following training with customized program by Lumos Labs.[11]
  • Kesler et al. found that women whose breast cancer had been treated with chemotherapy demonstrated improved executive function, such as cognitive flexibility, verbal fluency and processing speed after cognitive training. This work is published in Clinical Breast Cancer.[12]

However, other studies demonstrated no effects of training. In one study, a panel of experts, including eminent neuroscientists, examined Dr Kawashima's Brain Training, Mindfit and Lumosity. They found there was no scientific evidence to support claims that the gadgets or brain games can help improve memory or stave off the risk of illnesses such as dementia.[13] Follow-up studies attempting to replicate other studies with positive experimental results found no effect from the training.[14][15][16] Some have noted that the clinical trials cited on their website show that studies conducted used a very small sample size and that the methodology section fails to clearly explain how control groups were handled. Other studies have failed to demonstrate generalizable benefits of brain training.[17][18][19][20][21][22]

Meanwhile, no studies of Lumosity have shown significant changes to cognitive abilities. Yet, there is a number of ongoing large-scale studies that may prove otherwise.[citation needed]
