nfb No FeedBack. Don’t provide feedback on subjects response times and errors.
Without this option, DMDX will display messages like:
Correct 550 for a correct response with an RT of 550ms
Wrong for an incorrect response
This is too distracting for most of the tasks we use, but may be useful in some circumstances.
