Posit Science Corporation is an American company providing brain training software and services.
[5] The field of brain training has been driven by advertising making strong claims.
Starting in January 2015, the United States Federal Trade Commission (FTC) sued companies selling "brain training" programs or other products marketed as improving cognitive function, including WordSmart Corporation, the company that makes Lumosity, for deceptive advertising[6] and later that year the FTC also sued LearningRx; Posit was not sued by the FTC.
[7] A 2016 review of studies in the field found that there was some evidence that some of brain training programs improved performance on tasks in which users were trained, less evidence that improvements in performance generalize to related tasks, and almost no evidence that brain training generalizes to everyday cognitive performance; in addition most clinical studies were flawed.
[8] In 2017, a group of Australian scientists undertook a systematic review of what studies have been published of commercially available brain training programs in an attempt to give consumers and doctors credible information on which brain training programs are actually scientifically proved to work.
