Competing Interests

I have read the journal’s policy and the authors of this manuscript have the following competing interests: The present study examined effects of cognitive training with Lumosity on the NeuroCognitive Performance Test, both of which are produced by Lumos Labs, Inc. At the time of the study, all authors were paid employees of the company, and all hold stock in the company. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
