Active Memory (From ABC), was working really closely with a team of neuroscientists out of Australia. Lots of their data goes directly into research programs. Here's the blurb from their site:
"Active Memory has been developed in partnership with the University of Melbourne and the Florey Institute of Neuroscience and Mental Health. The program is built on a breakthrough statistical model that examines your game results and serves up a customised training schedule that challenges your brain at just the right level of difficulty. Most importantly, the program aims to measure the changes that are happening to your cognition, based on your training. Critically, your participation in Active Memory will contribute to one of the largest studies of its kind into brain training and its potential health benefits."
Was a really great team to work with. Had a very different angle from Luminosity and was held to very strict advertising controls through being a part of ABCs commercial arm.
