Here's a blurb from his site:
"RPG (Role-Playing Game) Research is an ongoing long-term series of projects that include studies on the therapeutic and educational aspects of role-playing games, with additional emphasis on determining any causality related to participation in role-playing gaming. This research includes tracking any other projects around the world that use role-playing games as educational or therapeutic intervention modalities...Dang. I'm impressed.
Utilizing a multidisciplinary approach, including disciplines from recreation therapy, psychology, cognitive neuroscience, education, and many other perspectives. RPG Research is a project of RPG Therapeutics LLC founded, and is the umbrella name under which the projects, website, communities, and other resources are identified. To date, this is a non-profit project founded (and funded) by William Hawkes-Robinson, with the helpful support of many others. This website is dedicated to supporting role-playing game research in general, and any other individuals or organizations interested in sharing research information about the therapeutic or educational aspects of role playing gaming."
