We welcome anyone to help develop the Psychtoolbox. At present, Mario Kleiner is doing almost all of the development. David Brainard and Denis Pelli participated in design. Tobias Wolf designed this website, and the online function reference and wrote the automatic documentation generator. Mario was a PhD student of computational vision at the Max Planck Institute in Tübingen and is currently employed as developer and maintainer of Psychtoolbox. David is a professor of psychology at University of Pennsylvania. Denis is a professor of psychology and neural science at New York University.
