Thanks for the file. Based on what you have there, it appears that for your trials with a key press you also want to control the amount of time that the stimulus is on the screen but still allow for these key presses to happen. If that is correct, take a look at the section named "Fixed Response Window/Stimulus Duration with an RT" here in the DirectRT manual: http://www.empirisoft.com/directrt/h..._rt_limits.htm. You will put the amount of time you want the stimulus to stay on the screen as the maximum value for the MinMax cell with the same number in the styles.drt file as the one in your trial.csv file.

To control the amount of time that the feedback in the last two rows of your trial.csv file stays on screen, simply put the number of milliseconds in the time cell of those rows. Right now, you have it programmed to keep the feedback onscreen for 2000 milliseconds.
