    Restricted time for word retrieval (case 21249)

    Hi all,

    I am struggling with setting up a restricted timed response for my Media Lab file. I have read a number of threads concerning timed responses using Min-Max, but it seems like restricting free-response answer is not possible with Direct RT. So I'm trying to use Media Lab file to implement my study paradigm but it is still not working very well and I would really appreciate it if anyone could please shout out any ideas you might have!

    What I am trying to do is to set the stimulus exposure time to 8 seconds for all the trials. I have some words that are partially shown, and others fully written. For the partial words, I want participants to write out the complete word, but I don't want them to be able to progress to the next trial before 8 seconds have ended so that each trial last for 8 seconds. I am able to set the response window to 8 seconds in which case the trials progress to the next trial after 8 seconds have passed, but the experiment is still allowing the participants to move on to the next trial BEFORE 8 seconds have passed when they press enter. Since I don't want participants to mindlessly race through the trials with responses, I want them to be unable to move on before 8 seconds have passed, but can't really find a way to do so at this point. I thought about disabling the enter key on the computer but then it would affect other experiments that needs the enter key...

    I have attached the Media Lab file below. Please let me know if you have any ideas-- it would be much appreciated
