The Psycholinguistics Lab in the Linguistics and TESOL Department at UT Arlington has been experimenting with a version of DMDX (created by Kenneth Forster and Jonathan Forster) that allows for remote testing. This web-deployable version of DMDX provides a convenient way for language researchers to gather experimental data on languages whose speakers are hard to come by.
This git respository contains the executables for the project at UTA. For additional information, please see Dr. Jeffrey Witzel's website at https://blog.uta.edu/jeffreyw/remote-dmdx/ or the Psycholinguistics Lab website at https://psycholinguisticslab.uta.edu.
