Why?

DMDX is a script interpreting system for screen control, stimulus presentation, and timing for cognitive experiments programmed by Jonathan Forster at the University of Arizona, USA.

DMDX is reliable, flexible, millisecond accurate and can be downloaded for free, thus it has become very popular among experimental researchers. However, setting up a DMDX-based experiment is burdensome due to its command based interface.

Visual DMDX is a HTML5-based web interface to set up simple experiments and export them to DMDX item files format in RTF.

Free

The use of Visual DMDX is (and always will be) free of charge :)

Moreover, we decided to release it under a free software license (Affero General Publice License version 3) to foster collaboration in its continuous improvement. Fork Visual DMDX's public repositoryi at Github.

We are very much interested in receiving your comments, suggestions and questions concerning Visual DMDX.

Please download, read and cite our paper 'Garaizar, P., & Reips, U.-D. (in press). Visual DMDX: A web-based authoring tool for DMDX, a Windows display program with millisecond accuracy. Behavior Research Methods.', if you are using Visual DMDX in your work.

Visual DMDX has been designed by Pablo Garaizar and Ulf-Dietrich Reips, and coded by Pablo Garaizar and Julen Telleria at the University of Deusto, Bilbao, Spain.

This website is based on Bootstrap (developed by Mark Otto and Jacob Thornton at Twitter) with the Flatly theme (designed by Thomas Park), KnockoutJS (developed by Steve Sanderson), and some PHP magic using Symfony's routing system (developed by Sensio Labs).
