I have been using DirectRT to create a task where one of the trials consists of a green button being shown on the screen and asking the the subject not to press any key [no-go trial] during 1000 milliseconds. After this time the next trial should be presented.

However, if the subject presses any key during 1000 milliseconds, I want the program to record the response as incorrect and move on to the next trial immediately. If the program do not press any key during those 1000 milliseconds as instructed, I want the program to record the response as correct. I was not able to find an example like this when reading your manual. I am sure there must be a specific command to set this trial up the way I want it, but I have not found it yet. I would highly appreciate your help.
