Hi Shimrit.
Like you saw, using the clear command in the stim column of a trial only clears the screen of stimuli while still waiting for a response. To make the trial continue even if participants did not make a response, let me quote from the Style Editor > MinMax-Setting RT Limits section of the DirectRT manual:
"By default, DirectRT will continue to the next event when an RT occurs. You can optionally have DirectRT wait until a fixed amount of time has passed instead. E.g., Let's say you want to present a stimulus and take and RT, but you want that stimulus on screen for 2000ms?no matter how fast the RT. To do this specify a max value of 2000ms (In your case, Shimrit, you would type 0-4000 in the MinMax field of the appropriate row in your Styles file). Then, when you request the RT in your input file, simply add the keyword "full" at the end like this:
rt:53,44,full
This method can be combined with the automatic continuation method above. If you want a fixed response window but you want the stimulus to disappear after the response, then add the term "clear-1" as in the following:
rt:53,44,full,clear-1"
Please let me know if you have any further questions.
