Yes, in fact, there is a now a GNAT sample included with DirectRT v2006 that you can use right out of the box or modify according to your needs. The use of "no response" as a valid response option is now documented in the v2006.2 user's guide, as well as in the online documentation here: www.empirisoft.com/directrt/help/directrt_samples_v2006_no_response_as_valid.htm)We are scrapping an antique reaction time program we had written for us in the DOS age. Our main need is for a program that will do Go-NoGo reaction time measurements. Can Direct RT be configured to record responses to NoGo signals?
It is essentially the first stab at the DirectRT version of the Go/No-go Association Task (GNAT) posted at Project Implicit (see http://projectimplicit.net/nosek/gnat/). Let us know if you have any luck with it or make changes to it that other users might find useful.
