[Lumosity](http://lumosity.com) is a popular website that claims to help you become a more intellectually capable individual. 

> Harness your brain's neuroplasticity and train your way to a brighter life"

- Is it truly possible to improve your IQ?

- Is IQ a good measure of Intelligence?

- Are they actually onto something, like PositScience? 

Here are some studies I have found that Lumosity use to support their claims:

* [New Approaches to Learning Using Neuroscience and Gaming:
A large scale, multi-site implementation of a web-based cognitive training program in academic settings](http://cdn.beacon.lumosity.com/assets/hcp/Ng-2012-L&B_poster_revised-ab5be2fb53ea918f0a1fa6e413be884d.pdf)

* [Enhancing visual attention and working memory with a Web-based cognitive training program](http://static.sl.lumosity.com/pdf/hardy_drescher_sarkar_kellet_scanlon_2011.pdf)

* [Changes in frontal-parietal activation and math skills performance following adaptive number sense training: preliminary results from a pilot study.](http://www.ncbi.nlm.nih.gov/pubmed/21714745?dopt=Abstract)

Lumosity has a user-community of over 35 million. There are likely to be duplicates and bots though but that is quite surprising. They seem to be amassing great profits and there are testimonies but those are only anecdotal evidence and not part of a well researched statistical study, and may even be fabricated.
